Researchers at the University of Ottawa have debunked the decade-old myth of metals being useless in photonics—the science and technology of light—with their findings, recently published in Nature Communications, expected to lead to many applications in the field of nanophotonics.
“We broke the record for the resonance quality factor (Q-factor) of a periodic array of metal nanoparticles by one order of magnitude compared to previous reports,” said senior author Dr. Ksenia Dolgaleva, Canada Research Chair in Integrated Photonics (Tier 2) and Associate Professor in the School of Electrical Engineering and Computer Science (EECS) at the University of Ottawa.
“It is a well-known fact that metals are very lossy when they interact with light, which means they cause the dissipation of electrical energy. The high losses compromise their use in optics and photonics. We demonstrated ultra-high-Q resonances in a metasurface (an artificially structured surface) comprised of an array of metal nanoparticles embedded inside a flat glass substrate. These resonances can be used for efficient light manipulating and enhanced light-matter interaction, showing metals are useful in photonics.”
“In previous works, researchers attempted to mitigate the adverse effect of losses to access favorable properties of metal nanoparticle arrays,” observed the co-lead author of the study Md Saad Bin-Alam, a uOttawa doctoral student in EECS.
“However, their attempts did not provide a significant improvement in the quality factors of the resonances of the arrays. We implemented a combination of techniques rather than a single approach and obtained an order-of-magnitude improvement demonstrating a metal nanoparticle array (metasurface) with a record-high quality factor.”
According to the researchers, structured surfaces – also called metasurfaces – have very promising prospects in a variety of nanophotonic applications that can never be explored using traditional natural bulk materials. Sensors, nanolasers, light beam shaping and steering are just a few examples of the many applications.
“Metasurfaces made of noble metal nanoparticles – gold or silver for instance – possess some unique benefits over non-metallic nanoparticles. They can confine and control light in a nanoscale volume that is less than one quarter of the wavelength of light (less than 100 nm, while the width of a hair is over 10 000 nm),” explained Md Saad Bin-Alam.
“Interestingly, unlike in non-metallic nanoparticles, the light is not confined or trapped inside the metal nanoparticles but is concentrated close to their surface. This phenomenon is scientifically called ‘localized surface plasmon resonances (LSPRs)’. This feature gives a great superiority to metal nanoparticles compared to their dielectric counterparts, because one could exploit such surface resonances to detect bio-organisms or molecules in medicine or chemistry. Also, such surface resonances could be used as the feedback mechanism necessary for laser gain. In such a way, one can realize a nanoscale tiny laser that can be adopted in many future nanophotonic applications, like light detection and ranging (LiDAR) for the far-field object detection.”
According to the researchers, the efficiency of these applications depends on the resonant Q-factors.
“Unfortunately, due to the high ‘absorptive’ and ‘radiative’ loss in metal nanoparticles, the LSPRs Q-factors are very low,” said co-lead author Dr. Orad Reshef, a postdoctoral fellow in the Department of Physics at the University of Ottawa.
“More than a decade ago, researchers found a way to mitigate the dissipative loss by carefully arranging the nanoparticles in a lattice. From such ‘surface lattice’ manipulation, a new ‘surface lattice resonance (SLR)’ emerges with suppressed losses. Until our work, the maximum Q-factors reported in SLRs was around a few hundred. Although such early reported SLRs were better than the low-Q LSPRs, they were still not very impressive for efficient applications. It led to the myth that metals are not useful for practical applications.”
A myth that the group was able to deconstruct during its work at the University of Ottawa’s Advanced Research Complex between 2017 and 2020.
“At first, we performed numerical modelling of a gold nanoparticle metasurface and were surprised to obtain quality factors of several thousand,” said Md Saad Bin-Alam, who primarily designed the metasurface structure.
“This value has never been reported experimentally, and we decided to analyze why and to attempt an experimental demonstration of such a high Q. We observed a very high-Q SLR of value nearly 2400, that is at least 10 times larger than the largest SLRs Q reported earlier.”
A discovery that made them realize that there’s still a lot to learn about metals.
“Our research proved that we are still far from knowing all the hidden mysteries of metal (plasmonic) nanostructures,” concluded Dr. Orad Reshef, who fabricated the metasurface sample. “Our work has debunked a decade-long myth that such structures are not suitable for real-life optical applications due to the high losses. We demonstrated that, by properly engineering the nanostructure and carefully conducting an experiment, one can improve the result significantly.”

There seems to be an explosion (metaphorically and only by Canadian standards) of interest in public perceptions/engagement/awareness of artificial intelligence (see my March 29, 2021 posting “Canada launches its AI dialogues” and these dialogues run until April 30, 2021 plus there’s this April 6, 2021 posting “UNESCO’s Call for Proposals to highlight blind spots in AI Development open ’til May 2, 2021” which was launched in cooperation with Mila-Québec Artificial Intelligence Institute).
Information and communications technologies have profoundly changed almost every aspect of life and business in the last two decades. While the digital revolution has brought about many positive changes, it has also created opportunities for criminal organizations and malicious actors to target individuals, businesses, and systems.
This assessment will examine promising practices that could help to address threats to public safety related to the use of digital technologies while respecting human rights and privacy.
The use of artificial intelligence (AI) and machine learning in science and engineering has the potential to radically transform the nature of scientific inquiry and discovery and produce a wide range of social and economic benefits for Canadians. But, the adoption of these technologies also presents a number of potential challenges and risks.
This assessment will examine the legal/regulatory, ethical, policy and social challenges related to the use of AI technologies in scientific research and discovery.

The Council of Canadian Academies (CCA) has formed an Expert Panel to examine a broad range of factors related to the use of artificial intelligence (AI) technologies in scientific research and discovery in Canada. Teresa Scassa, SJD, Canada Research Chair in Information Law and Policy at the University of Ottawa, will serve as Chair of the Panel.
“AI and machine learning may drastically change the fields of science and engineering by accelerating research and discovery,” said Dr. Scassa. “But these technologies also present challenges and risks. A better understanding of the implications of the use of AI in scientific research will help to inform decision-making in this area and I look forward to undertaking this assessment with my colleagues.”
As Chair, Dr. Scassa will lead a multidisciplinary group with extensive expertise in law, policy, ethics, philosophy, sociology, and AI technology. The Panel will answer the following question:
What are the legal/regulatory, ethical, policy and social challenges associated with deploying AI technologies to enable scientific/engineering research design and discovery in Canada?
“We’re delighted that Dr. Scassa, with her extensive experience in AI, the law and data governance, has taken on the role of Chair,” said Eric M. Meslin, PhD, FRSC, FCAHS, President and CEO of the CCA. “I anticipate the work of this outstanding panel will inform policy decisions about the development, regulation and adoption of AI technologies in scientific research, to the benefit of Canada.”
The CCA was asked by the National Research Council of Canada (NRC), along with co-sponsors CIFAR, CIHR, NSERC, and SSHRC, to address the question. More information can be found here.

Who is the expert panel?
Putting together a Canadian panel is an interesting problem especially so when you’re trying to find people of expertise who can also represent various viewpoints both professionally and regionally. Then, there are gender, racial, linguistic, urban/rural, and ethnic considerations.
Eight of the panelists could be said to be representing various regions of Canada. Five of those eight panelists are based in central Canada, specifically, Ontario (Ottawa) or Québec (Montréal). The sixth panelist is based in Atlantic Canada (Nova Scotia), the seventh panelist is based in the Prairies (Saskatchewan), and the eighth panelist is based in western Canada, (Vancouver, British Columbia).
The two panelists bringing an international perspective to this project are both based in Europe, specifically, Sweden and the UK.
(sigh) It would be good to have representation from another part of the world. Asia springs to mind as researchers in that region are very advanced in their AI research and applications meaning that their experts and ethicists are likely to have valuable insights.
Four of the ten panelists are women, which is closer to equal representation than some of the other CCA panels I’ve looked at.
As for Indigenous and BIPOC representation, unless one or more of the panelists chooses to self-identify in that fashion, I cannot make any comments. It should be noted that more than one expert panelist focuses on social justice and/or bias in algorithms.
Network of relationships
As you can see, the CCA descriptions for the individual members of the expert panel are a little brief. So, I did a little digging and In my searches, I noticed what seems to be a pattern of relationships among some of these experts. In particular, take note of the Canadian Institute for Advanced Research (CIFAR) and the AI Advisory Council of the Government of Canada.
Mr. Billot is a member of the faculty at HEC Montréal [graduate business school of the Université de Montréal] as an adjunct professor of management and the lead for the CreativeDestructionLab (CDL) and NextAi program in Montreal.
Julien Billot has been President and Chief Executive Officer of Yellow Pages Group Corporation (Y.TO) in Montreal, Quebec. Previously, he was Executive Vice President, Head of Media and Member of the Executive Committee of Solocal Group (formerly PagesJaunes Groupe), the publicly traded and incumbent local search business in France. Earlier experience includes serving as CEO of the digital and new business group of Lagardère Active, a multimedia branch of Lagardère Group and 13 years in senior management positions at France Telecom, notably as Chief Marketing Officer for Orange, the company’s mobile subsidiary.
Mr. Billot is a graduate of École Polytechnique (Paris) and from Telecom Paris Tech. He holds a postgraduate diploma (DEA) in Industrial Economics from the University of Paris-Dauphine.
Wendy Hui Kyong Chun (British Columbia) has a profile on the Simon Fraser University (SFU) website, which provided one of the more interesting (to me personally) biographies,
Wendy Hui Kyong Chun is the Canada 150 Research Chair in New Media at Simon Fraser University, and leads the Digital Democracies Institute which was launched in 2019. The Institute aims to integrate research in the humanities and data sciences to address questions of equality and social justice in order to combat the proliferation of online “echo chambers,” abusive language, discriminatory algorithms and mis/disinformation by fostering critical and creative user practices and alternative paradigms for connection. It has four distinct research streams all led by Dr. Chun: Beyond Verification which looks at authenticity and the spread of disinformation; From Hate to Agonism, focusing on fostering democratic exchange online; Desegregating Network Neighbourhoods, combatting homophily across platforms; and Discriminating Data: Neighbourhoods, Individuals and Proxies, investigating the centrality of race, gender, class and sexuality [emphasis mine] to big data and network analytics.
I’m glad to see someone who has focused on ” … the centrality of race, gender, class and sexuality to big data and network analytics.” Even more interesting to me was this from her CV (curriculum vitae),
Professor, Department of Modern Culture and Media, Brown University, July 2010-June 2018
.•Affiliated Faculty, Multimedia & Electronic Music Experiments (MEME), Department of Music,2017.
•Affiliated Faculty, History of Art and Architecture, March 2012-
.•Graduate Field Faculty, Theatre Arts and Performance Studies, Sept 2008-.[sic]
[all emphases mine]
And these are some of her credentials,
Ph.D., English, Princeton University, 1999. •Certificate, School of Criticism and Theory, Dartmouth College, Summer 1995.
M.A., English, Princeton University, 1994.
B.A.Sc., Systems Design Engineering and English, University of Waterloo, Canada, 1992. •first class honours and a Senate Commendation for Excellence for being the first student to graduate from the School of Engineering with a double major
It’s about time the CCA started integrating some of kind of arts perspective into their projects. (Although, I can’t help wondering if this was by accident rather than by design.)
Marc Antoine Dilhac, an associate professor at l’Université de Montréal, he, like Billot, graduated from a French university, in his case, the Sorbonne. Here’s more from Dilhac’s profile on the Mila website,
Marc-Antoine Dilhac (Ph.D., Paris 1 Panthéon-Sorbonne) is a professor of ethics and political philosophy at the Université de Montréal and an associate member of Mila – Quebec Artificial Intelligence Institute. He currently holds a CIFAR [Canadian Institute for Advanced Research] Chair in AI ethics (2019-2024), and was previously Canada Research Chair in Public Ethics and Political Theory 2014-2019. He specialized in theories of democracy and social justice, as well as in questions of applied ethics. He published two books on the politics of toleration and inclusion (2013, 2014). His current research focuses on the ethical and social impacts of AI and issues of governance and institutional design, with a particular emphasis on how new technologies are changing public relations and political structures.
In 2017, he instigated the project of the Montreal Declaration for a Responsible Development of AI and chaired its scientific committee. In 2020, as director of Algora Lab, he led an international deliberation process as part of UNESCO’s consultation on its recommendation on the ethics of AI.
In 2019, he founded Algora Lab, an interdisciplinary laboratory advancing research on the ethics of AI and developing a deliberative approach to the governance of AI and digital technologies. He is co-director of Deliberation at the Observatory on the social impacts of AI and digital technologies (OBVIA), and contributes to the OECD Policy Observatory (OECD.AI) as a member of its expert network ONE.AI.
He sits on the AI Advisory Council of the Government of Canada and co-chair its Working Group on Public Awareness.
Formerly known as Mila only, Mila – Quebec Artificial Intelligence Institute is a beneficiary of the 2017 Canadian federal budget’s inception of the Pan-Canadian Artificial Intelligence Strategy, which named CIFAR as an agency that would benefit as the hub and would also distribute funds for artificial intelligence research to (mainly) three agencies: Mila in Montréal, the Vector Institute in Toronto, and the Alberta Machine Intelligence Institute (AMII; Edmonton).
Consequently, Dilhac’s involvement with CIFAR is not unexpected but when added to his presence on the AI Advisory Council of the Government of Canada and his role as co-chair of its Working Group on Public Awareness, one of the co-sponsors for this future CCA report, you get a sense of just how small the Canadian AI ethics and public awareness community is.
Add in CIFAR’s Open Dialogue: AI in Canada series (ongoing until April 30, 2021) which is being held in partnership with the AI Advisory Council of the Government of Canada (see my March 29, 2021 posting for more details about the dialogues) amongst other familiar parties and you see a web of relations so tightly interwoven that if you could produce masks from it you’d have superior COVID-19 protection to N95 masks.
These kinds of connections are understandable and I have more to say about them in my final comments.
B. Courtney Doagoo has a profile page at the University of Ottawa, which fills in a few information gaps,
As a Fellow, Dr. Doagoo develops her research on the social, economic and cultural implications of AI with a particular focus on the role of laws, norms and policies [emphasis mine]. She also notably advises Dr. Florian Martin-Bariteau, CLTS Director, in the development of a new research initiative on those topical issues, and Dr. Jason Millar in the development of the Canadian Robotics and Artificial Intelligence Ethical Design Lab (CRAiEDL).
Dr. Doagoo completed her Ph.D. in Law at the University of Ottawa in 2017. In her interdisciplinary research, she used empirical methods to learn about and describe the use of intellectual property law and norms in creative communities. Following her doctoral research, she joined the World Intellectual Property Organization’s Coordination Office in New York as a legal intern and contributed to developing the joint initiative on gender and innovation in collaboration with UNESCO and UN Women. She later joined the International Law Research Program at the Centre for International Governance Innovation as a Post-Doctoral Fellow, where she conducted research in technology and law focusing on intellectual property law, artificial intelligence and data governance.
Dr. Doagoo completed her LL.L. at the University of Ottawa, and LL.M. in Intellectual Property Law at the Benjamin N. Cardozo School of Law [a law school at Yeshiva University in New York City]. In between her academic pursuits, Dr. Doagoo has been involved with different technology start-ups, including the one she is currently leading aimed at facilitating access to legal services. She’s also an avid lover of the arts and designed a course on Arts and Cultural Heritage Law taught during her doctoral studies at the University of Ottawa, Faculty of Law.
It’s probably because I don’t know enough but this “the role of laws, norms and policies” seems bland to the point of meaningless. The rest is more informative and brings it back to the arts with Wendy Hui Kyong Chun at SFU.
Doagoo’s LinkedIn profile offers an unexpected link to this expert panel’s chairperson, Teresa Scassa (in addition to both being lawyers whose specialties are in related fields and on faculty or fellow at the University of Ottawa),
Soft-funded Research Bursary
Dr. Teresa Scassa
I’m not suggesting any conspiracies; it’s simply that this is a very small community with much of it located in central and eastern Canada and possible links into the US. For example, Wendy Hui Kyong Chun, prior to her SFU appointment in December 2018, worked and studied in the eastern US for over 25 years after starting her academic career at the University of Waterloo (Ontario).
Abhishek Gupta provided me with a challenging search. His LinkedIn profile yielded some details (I’m not convinced the man sleeps), Note: I have made some formatting changes and removed the location, ‘Montréal area’ from some descriptions

Exhausting, eh? He also has an eponymous website and the Montreal AI Ethics Institute can found here where Gupta and his colleagues are “Democratizing AI ethics literacy.” My hat’s off to Gupta getting on an expert panel for CCA is quite an achievement for someone without the usual academic and/or industry trappings.
Richard Isnor, based in Nova Scotia and associate vice president of research & graduate studies at St. Francis Xavier University (StFX), seems to have some connection to northern Canada (see the reference to Nunavut Research Institute below); he’s certainly well connected to various federal government agencies according to his profile page,
Prior to joining StFX, he was Manager of the Atlantic Regional Office for the Natural Sciences and Engineering Research Council of Canada (NSERC), based in Moncton, NB. Previously, he was Director of Innovation Policy and Science at the International Development Research Centre in Ottawa and also worked for three years with the National Research Council of Canada [NRC] managing Biotechnology Research Initiatives and the NRC Genomics and Health Initiative.
Richard holds a D. Phil. in Science and Technology Policy Studies from the University of Sussex, UK; a Master’s in Environmental Studies from Dalhousie University [Nova Scotia]; and a B. Sc. (Hons) in Biochemistry from Mount Allison University [New Burnswick]. His primary interest is in science policy and the public administration of research; he has worked in science and technology policy or research administrative positions for Environment Canada, Natural Resources Canada, the Privy Council Office, as well as the Nunavut Research Institute. [emphasis mine]
I don’t know what Dr. Isnor’s work is like but I’m hopeful he (along with Spiteri) will be able to provide a less ‘big city’ perspective to the proceedings.
(For those unfamiliar with Canadian cities, Montreal [three expert panelists] is the second largest city in the country, Ottawa [two expert panelists] as the capital has an outsize view of itself, Vancouver [one expert panelist] is the third or fourth largest city in the country for a total of six big city representatives out of eight Canadian expert panelists.)
Ross D. King, professor of machine intelligence at Sweden’s Chalmers University of Technology, might be best known for Adam, also known as, Robot Scientist. Here’s more about King, from his Wikipedia entry (Note: Links have been removed),
King completed a Bachelor of Science degree in Microbiology at the University of Aberdeen in 1983 and went on to study for a Master of Science degree in Computer Science at the University of Newcastle in 1985. Following this, he completed a PhD at The Turing Institute [emphasis mine] at the University of Strathclyde in 1989 for work on developing machine learning methods for protein structure prediction.
King’s research interests are in the automation of science, drug design, AI, machine learning and synthetic biology. He is probably best known for the Robot Scientist project which has created a robot that can:
hypothesize to explain observations
devise experiments to test these hypotheses
physically run the experiments using laboratory robotics
… a laboratory robot created and developed by a group of scientists including Ross King, Kenneth Whelan, Ffion Jones, Philip Reiser, Christopher Bryant, Stephen Muggleton, Douglas Kell and Steve Oliver.
… Adam became the first machine in history to have discovered new scientific knowledge independently of its human creators.
Sabina Leonelli, professor of philosophy and history of science at the University of Exeter, is the only person for whom I found a Twitter feed (@SabinaLeonelli). Here’s a bit more from her Wikipedia entry Note: Links have been removed),
Originally from Italy, Leonelli moved to the UK for a BSc degree in History, Philosophy and Social Studies of Science at University College London and a MSc degree in History and Philosophy of Science at the London School of Economics. Her doctoral research was carried out in the Netherlands at the Vrije Universiteit Amsterdam with Henk W. de Regt and Hans Radder. Before joining the Exeter faculty, she was a research officer under Mary S. Morgan at the Department of Economic History of the London School of Economics.
Leonelli is the Co-Director of the Exeter Centre for the Study of the Life Sciences (Egenis) and a Turing Fellow at the Alan Turing Institute [emphases mine] in London. She is also Editor-in-Chief of the international journal History and Philosophy of the Life Sciences and Associate Editor for the Harvard Data Science Review. She serves as External Faculty for the Konrad Lorenz Institute for Evolution and Cognition Research.
Raymond J. Spiteri, professor and director of the Centre for High Performance Computing, Department of Computer Science at the University of Saskatchewan, has a profile page at the university the likes of which I haven’t seen in several years perhaps due to its 2013 origins. His other university profile page can best be described as minimalist.
Raymond Spiteri is a Professor in the Department of Computer Science at the University of Saskatchewan. He performed his graduate work as a member of the Institute for Applied Mathematics at the University of British Columbia. He was a post-doctoral fellow at McGill University and held faculty positions at Acadia University and Dalhousie University before joining USask in 2004. He serves on the Executive Committee of the WestGrid High-Performance Computing Consortium with Compute/Calcul Canada. He was a MITACS Project Leader from 2004-2012 and served in the role of Mitacs Regional Scientific Director for the Prairie Provinces between 2008 and 2011.
Spiteri’s areas of research are numerical analysis, scientific computing, and high-performance computing. His area of specialization is the analysis and implementation of efficient time-stepping methods for differential equations. He actively collaborates with scientists, engineers, and medical experts of all flavours. He also has a long record of industry collaboration with companies such as IBM and Boeing.
Spiteri has been lifetime member of CAIMS/SCMAI since 2000. He helped co-organize the 2004 Annual Meeting at Dalhousie and served on the Cecil Graham Doctoral Dissertation Award Committee from 2005 to 2009, acting as chair from 2007. He has been an active participant in CAIMS, serving several times on the Scientific Committee for the Annual Meeting, as well as frequently attending and organizing mini-symposia. Spiteri believes it is important for applied mathematics to play a major role in the efforts to meet Canada’s most pressing societal challenges, including the sustainability of our healthcare system, our natural resources, and the environment.
Another biographical note: I obtained my B.Sc. degree in Applied Mathematics from the University of Western Ontario [also known as, Western University] in 1990. My advisor was Dr. M.A.H. (Paddy) Nerenberg, after whom the Nerenberg Lecture Series is named. Here is an excerpt from the description, put here is his honour, as a model for the rest of us:
The Nerenberg Lecture Series is first and foremost about people and ideas. Knowledge is the true treasure of humanity, accrued and passed down through the generations. Some of it, particularly science and its language, mathematics, is closed in practice to many because of technical barriers that can only be overcome at a high price. These technical barriers form part of the remarkable fractures that have formed in our legacy of knowledge. We are so used to those fractures that they have become almost invisible to us, but they are a source of profound confusion about what is known.
The Nerenberg Lecture is named after the late Morton (Paddy) Nerenberg, a much-loved professor and researcher born on 17 March– hence his nickname. He was a Professor at Western for more than a quarter century, and a founding member of the Department of Applied Mathematics there. A successful researcher and accomplished teacher, he believed in the unity of knowledge, that scientific and mathematical ideas belong to everyone, and that they are of human importance. He regretted that they had become inaccessible to so many, and anticipated serious consequences from it. [emphases mine] The series honors his appreciation for the democracy of ideas. He died in 1993 at the age of 57.
So, we have the expert panel.
Thoughts about the panel and the report
As I’ve noted previously here and elsewhere, assembling any panels whether they’re for a single event or for a longer term project such as producing a report is no easy task. Looking at the panel, there’s some arts representation, smaller urban centres are also represented, and some of the members have experience in more than one region in Canada. I was also much encouraged by Spiteri’s acknowledgement of his advisor’s, Morton (Paddy) Nerenberg, passionate commitment to the idea that “scientific and mathematical ideas belong to everyone.”
Kudos to the Council of Canadian Academies (CCA) organizers.
That said, this looks like an exceptionally Eurocentric panel. Unusually, there’s no representation from the US unless you count Chun who has spent the majority of her career in the US with only a little over two years at Simon Fraser University on Canada’s West Coast.
There’s weakness to a strategy (none of the ten or so CCA reports I’ve reviewed here deviates from this pattern) that seems to favour international participants from Europe and/or the US (also, sometimes, Australia/New Zealand). This leaves out giant chunks of the international community and brings us dangerously close to an echo chamber.
The same problem exists regionally and with various Canadian communities, which are acknowledged more in spirit than in actuality, e.g., the North, rural, indigenous, arts, etc.
Getting back to the ‘big city’ emphsais noted earlier, two people from Ottawa and three from Montreal; half of the expert panel lives within a two hour train ride of each other. (For those who don’t know, that’s close by Canadian standards. For comparison, a train ride from Vancouver to Seattle [US] is about four hours, a short trip when compared to a 24 hour train trip to the closest large Canadian cities.)
I appreciate that it’s not a simple problem but my concern is that it’s never acknowledged by the CCA. Perhaps they could include a section in the report acknowledging the issues and how the expert panel attempted to address them , in other words, transparency. Coincidentally, transparency, which has been related to trust, have both been identified as big issues with artificial intelligence.
As for solutions, these reports get sent to external reviewers and, prior to the report, outside experts are sometimes brought in as the panel readies itself. That would be two opportunities afforded by their current processes.
Anyway, good luck with the report and I look forward to seeing it.
The night sky has inspired speculation, discovery, and stories throughout time and from all the peoples of this planet. The information derived from observing the stars and moon has led to voyages on land, on sea, through space, and into the recesses of minds and hearts.
Currently, an ancient celestial practice, celebration of solstices and equinoxes seems to be gaining popularity and acceptance.
Indigenous Star Knowledge Symposia: A series of local and international gatherings, on the land and online
Organised by Ingenium in collaboration with the Institute of Indigenous Research and Studies at the University of Ottawa, and hosted on traditional Algonquin Anishnaabeg territory, this series of symposia (chosen on the dates of the Fall equinox, Winter solstice, Spring equinoxes and Summer solstice) will combine spiritual ceremony, presentations, activities and dialogue, both online and on the land. The symposia will feature gatherings of Indigenous Knowledge Keepers, Elders, educators and scholars to share and exchange towards reclaiming, preserving, and revitalizing Star Knowledge with Indigenous communities worldwide.
Our original plan was to have a symposium in September 2020, but due to Covid-19 we have reshaped the entire program to spread out the timeline while combining physical and digitally-inclusive experiences. This blended format greatly expands our original intent to offer a space for teaching and learning, while bringing hope and healing through the Indigenous Star Knowledge and our work.
Fall Equinox: Protocols before Knowledge, Seasonal and regional themes
September 21, 2020 (7 p.m. Est Ottawa, Canada); September 22, 2020 (9:00 a.m. Lismore, Australia)
For Indigenous people astronomy and cosmology are intricately intertwined. Star Knowledge, like everything else, is all about relationships and teaches us our place in the universe.
Shawn Wilson is Opaskwayak Cree from Manitoba. He works at Gnibi College of Indigenous Australian Peoples and is also an Adjunct Professor at Østfold University College in Norway. Shawn will discuss how understanding Indigenous Star Knowledge develops a deeper understanding of the very nature of reality. To gain this understanding requires us to develop deeper relationships with Sky Country.
Stuart Barlo is a Yuin man from the south coast of New South Wales, and is Dean of Gnibi College of Indigenous Australian Peoples. Stuart will talk about the journey of being able to speak about Sky Country. The journey requires learning how to prepare yourself and create a safe space to develop relationship with Sky Country.

It gets a little confusing but I gather that the symposia are linked to a larger initiative, which has its roots in a 2017 exhibition (co-curated by Wilfred Buck and Annette S. Lee) at Canada’s Science and Technology Museum. ***Video link removed Dec. 8, 2020***
One Sky, Many Worlds; Indigenous Voices in Astronomy
I gather various parties have been working together to produce not only the symposia but a new traveling exhibition “One Sky, Many Worlds; Indigenous Voices in Astronomy.”
I was going to call this item a brochure but its URL includes the words “exhibition book.” Regardless, it’s where you can get more details about “One Sky, Many Worlds” and how it was developed. Do take a look at it, there are many beautiful images, including Margaret Nazon’s beadworks of art, one of which I featured at the beginning of this posting. There are many works of Indigenous astronomy-based art featured in the ‘brochure’. For some reason, the text is white against a dark background. Perhaps they were trying to evoke the stars against the night sky? Unfortunately, it makes the text less readable, which would seem to defeat the purpose of bothering with text in the first place. Also, it can lead to having to deal with cranky writers who worry their work won’t be read. (Just a thought)
New Partnership with Ingenium: Canada’s Museums of Science and Innovation
Nomad are proud to be selected as Ingenium’s partner to develop and tour an exciting new international travelling exhibition ‘One Sky, Many Worlds: Indigenous Voices in Astronomy’. This ground-breaking new exhibition will illustrate in a spectacular immersive display environment how for tens of thousands of years Indigenous people have been building a relationship with the night sky.
The exhibition will showcase artifacts representing global collections, whilst numerous mechanical and digital interactive elements will enhance visitors’ learning and understanding in an engaging, active way that reminds every human being that we come from the stars.
Led by Indigenous knowledge keepers, One Sky, Many Worlds: Indigenous Voices in Astronomy, is an 8,000 sq ft traveling exhibition that explores Indigenous Star Knowledge from locations around the globe. Featuring content from North America, South Africa, Australia, Mexico, South America, Asia, Hawaii, and New Zealand, One Sky asks questions, and shares experiences that will resonate with all people who look up and wonder about the night sky. The exhibition is available for tour internationally from summer 2021. [emphasis mine]
Nomad Exhibitions are innovative creators of international museum quality touring exhibitions.
Nomad offers a unique portfolio of high quality touring exhibitions combining curatorial excellence, state of the art design and seamless turnkey production. Our exhibitions are designed to facilitate exceptional international collaborations between cultural institutions on major exhibition projects, providing museum professionals with a tailored exhibition hosting experience.
Nomad Exhibitions is located in Edinburgh, Scotland, UK.
One Sky, Many Worlds is a collaborative exhibition led by Indigenous Knowledge Keepers, both young and old, from around the world. The exhibition explores the enduring relationship and connection that Indigenous people have with the night sky and how it has provided –and continues to provide – a practical, cultural, and spiritual guidebook for life.
One Sky, Many Worlds is, at its core, experiential. A strong emphasis on exceptional objects and intriguing ideas will be carefully complemented by a variety of interactive elements and spaces designed to engage visitors in active participation.
Each exhibition section will feature an immersive experience, audio visual content, and a selection of digital interactives, many of which will be touch free. For example, visitors will be transported from the Mississippi through the Milky Way on to the Pacific Ocean via a beautiful, [emphasis mine] immersive projection experience; visitors will be engaged in stories as told by Indigenous Elders in their own language; and visitors will also have the opportunity to participate in dynamic activities that show the links between earth and sky and allow them to see the constellations in a whole new way.
The example is a bit puzzling since ‘the Mississippi’ could mean either the ‘state of Mississippi’ or the ‘Mississippi River’ neither of which have any connection to the Pacific Ocean. But, perhaps astronomy buffs would understand this better than I do.
As to why either the state or the river would be the starting point for transportation via the Milky Way, that is a mystery. Especially after taking a look at Sharmila Kuthunu’s July 1, 2019 article, “How to See the Milky Way in 5 Easy Steps” for Space Tourism Guide,
Home to 400 billion stars, our galaxy is a barred spiral that spans 100,000 light years in diameter. While that might seem huge, the Milky Way is only clearly visible from April through October in the northern hemisphere and is hidden below the horizon for half the year.
It rises in the southeast, crosses over the horizon and sets in the southwest. Since it rises and sets in the southern hemisphere, those living in the south can see it directly overhead. The largest view of the galaxy can be seen from southern hemisphere destinations like South Africa, Chile, and Australia [emphasis mine].
Given that there was a global collaboration and the Milky Way is visible from any number of starting points, the choice of whichever Mississippi the writer intended to highlight seems odd. (See geography of Mississippi River; geography of Mississippi state [be sure to follow the red arrow to the green rectangle bordering the Gulf of Mexico])
Most likely, it’s my ignorance showing.
Plus, when I saw Nomad was offering an example, I was hoping there’d be a description or a story representing Indigenous astronomy. If you look at the brochure/exhibition book you’ll see they had a broad range of Indigenous societies represented on the team. The nomad description seems like a lost opportunity.
Regardless of my nitpicking, both the symposia and the travelling exhibition are exciting and I hope they get the attention they deserve.
If you’re as ignorant about astronomy as I am, you might find this piece about the Milky Way on the US National Aeronautics and Space Administration (NASA) website helpful.
Part 1 covered some of the more formal aspects science culture in Canada, such as science communication education programmes, mainstream media, children’s science magazines, music, etc. Part 2 covered science festivals, art/sci or sciart (depending on who’s talking, informal science get togethers such ‘Cafe Sccientifque’, etc.
This became a much bigger enterprise than I anticipated and so part 3 is stuffed with the do-it-yourself (DIY) biology movement in Canada, individual art/sci or lit/sci projects, a look at what the mathematicians have done and are doing, etc. But first there’s the comedy.
Comedy, humour, and science
Weirdly, Canadians like to mix their science fiction (scifi) movies with humour. (I will touch on more scifi later in this post but it’s too big a topic to cover inadequately, let alone adequately, in this review.) I post as my evidence of the popularity of comedy science fiction films, this from the Category: Canadian science fiction films Wikipedia webpage,
As you see, comedy science fiction is the second most populated category. Also, the Wikipedia time frame is much broader than mine but I did check one Canadian science fiction comedy film, Bang Bang Baby, a 2014 film, which, as it turns out, is also a musical.
Daniel Chai is a Vancouver-based writer, comedian, actor and podcaster. He is co-host of The Fear of Science podcast, which combines his love of learning with his love of being on a microphone. Daniel is also co-founder of The Fictionals Comedy Co and the creator of Improv Against Humanity, and teaches improv at Kwantlen Polytechnic University. He is very excited to be part of Vancouver Podcast Festival, and thanks everyone for listening!
Jeff is the producer and co-host of The Fear of Science. By day, he is a graphic designer/digital developer [according to his LinkedIn profile, he works at Science World], and by night he is a cosplayer, board gamer and full-time geek. Jeff is passionate about all things science, and has been working in science communication for over 4 years. He brings a general science knowledge point of view to The Fear of Science.
Here’s more about The Fear of Science from its homepage (where you will also find links to their podcasts),
A podcast that brings together experts and comedians for an unfiltered discussion about complicated and sometimes controversial science fears in a fun and respectful way.
This podcast seems to have taken life in August 2018.(Well, that’s as far back as the Archived episodes stretch on the website.)
This is Vancolour is a podcast hosted by Mo Amir and you will find this description on the website,

Cartoonist, writer, and educator, Raymond Nakamura produces work for Telus Science World and the Science Borealis science aggregator. His website is known as Raymond’s Brain features this image,
Much has been happening on this front. First for anyone unfamiliar with do-it-yourself biology, here’s more from its Wikipedia entry,
Do-it-yourself biology (DIY biology, DIY bio) is a growing biotechnological social movement in which individuals, communities, and small organizations study biology and life science using the same methods as traditional research institutions. DIY biology is primarily undertaken by individuals with extensive research training from academia or corporations, who then mentor and oversee other DIY biologists with little or no formal training. This may be done as a hobby, as a not-for-profit endeavour for community learning and open-science innovation, or for profit, to start a business.
A January 21, 2020 posting here listed the second Canadian DIY Biology Summit organized by the Public Health Agency of Canada (PHAC). It was possible to attend virtually from any part of Canada. The first meeting was in 2016 (you can see the agenda here). You’ll see in the agenda for the 2nd meeting in 2020 that there have been a few changes as groups rise into and fall out of existence.
From the 2020 agenda, here’s a list representing the players in Canada’s DIYbio scene,
Most of these organizations (e.g., Victoria Makerspace, Synbiota, Bricobio, etc.) seem to be relatively new (founded in 2009 or later) which is quite exciting to think about. This March 13, 2016 article in the Vancouver Observer gives you a pretty good overview of the DIY biology scene in Canada at the time while providing a preview of the then upcoming first DIY Biology summit.
*The Open Science Network in Vancouver was formerly known as DIYbio YVR. I’m not sure when the name change occurred but this July 17, 2018 article by Emily Ng for The Ubyssey (a University of British Columbia student newspaper) gives a little history,
In 2009, a group of UBC students and staff recognized these barriers and teamed up to democratize science, increase its accessibility and create an interdisciplinary platform for idea exchange. They created the Open Science Network (OSN).
The Open Science Network is a non-profit society that serves the science and maker community through education, outreach and the provision of space. Currently, they run an open community lab out of the MakerLabs space on East Cordova and Main street, which is a compact space housing microscopes, a freezer, basic lab equipment and an impressive amount of activity.
The lab is home to a community of citizen scientists, professional scientists, artists, designers and makers of all ages who are pursuing their own science projects.
Members who are interested in lab work can receive some training in “basic microbiology techniques like pipetting, growing bacteria, using the Polymerase Chain Reaction machine (PCR) [to amplify DNA] and running gels [through a gel ectrophoresis machine to separate DNA fragments by size] from Scott Pownall, a PhD graduate from UBC and the resident microbiologist,” said Wong [ Wes Wong, a staff member of UBC Botany and a founding member of OSN].
The group has also made further efforts to serve their members by offering more advanced synthetic biology classes and workshops at their lab.
There is another organization called ‘Open Science Network’ (an ethnobiology group and not part of the Vancouver organization). Here is a link to the Vancouver-based Open Science Network (a community science lab) where they provide further links to all their activities including a regular ‘meetup’.
I have poetry, a book, a television adaptation, three plays with mathematics and/or physics themes and more.
In 2012 there was a night of poetry readings in Vancouver. What made it special was that five poets had collaborated with five scientists (later amended to four scientists and a landscape architect) according to my December 4, 2012 posting. The whole thing was conceptualized and organized by Aileen Penner who went on to produce a chapbook of the poetry. She doesn’t have any copies available currently but you can contact her on her website’s art/science page if you are interested in obtaining a copy. She doesn’t seem to have organized any art/science projects since. For more about Aileen Penner who is a writer and poet, go to her website here.
The Banff International Research Station (BIRS) it’s all about the mathematics) hosted a workshop for poets and mathematicians way back in 2011. I featured it (Mathematics: Muse, Maker, and Measure of the Arts) after the fact in my January 9, 2012 posting (scroll down about 30% of the way). If you have the time, do click on my link to Nassif Ghoussoub’s post on his blog (Piece of Mind) about mathematicians, poetry, and the arts. It’s especially interesting in retrospect as he is now the executive director for BIRS, which no longer seems to have workshops that meld any of the arts with mathematics, and science.
That sadly seems to be it for poetry and the sciences, including mathematics. If you know of any other poetry/science projects or readings, etc. in Canada during the 2010-9 decade, please let me know in the comments.
Karl Schroeder, a Canadian science fiction author, has written many books but of particular interest here are two futuristic novels for the Canadian military.The 2005 novel, Crisis in Zefra, doesn’t fit the time frame I’ve established for this review but the the 2014 novel, Crisis in Urla (scroll down) fits in nicely. His writing is considered ‘realistic’ science fiction in that it’s based on science research and his work is also associated with speculative realism (from his Wikipedia entry; Note: Links have been removed),
Karl Schroeder (born September 4, 1962) is a Canadianscience fiction author. His novels present far-future speculations on topics such as nanotechnology, terraforming, augmented reality, and interstellar travel, and are deeply philosophical.
The other author I’m mentioning here is Margaret Atwood. The television adaptation of her book, ‘The Handmaid’s Tale’ has turned a Canadian literary superstar into a supernova (an exploding star whose luminosity can be the equivalent of an entire galaxy). In 2019, she won the Booker Prize, for the second time for ‘The Testaments’ (a followup to ‘The Handmaid’s Tale’), sharing it with Bernardine Evaristo and her book ‘Girl, Woman, Other’. Atwood has described her work (The Handmaid’s Tale, and others) as speculative fiction rather than science fiction. For me, she bases her speculation on the social sciences and humanities, specifically history (read her Wikipedia entry for more).
In 2017 with the television adaptation of ‘The Handmaid’s Tale’, Atwood’s speculative fiction novel became a pop culture phenomenon. Originally published in 1985, the novel was also adapted for a film in 1990 and for an opera in 2000 before it came to television, according to its Wikipedia entry.
There’s a lot more out there, Schroeder and Atwood are just two I’ve stumbled across.
I have drama, musical comedy and acting items.
Pi Theatre’s (Vancouver) mathematically-inclined show, ‘Long Division‘, ran in April 2017 and was mentioned in my April 20, 2017 posting (scroll down about 50% of the way).
This theatrical performance of concepts in mathematics runs from April 26 – 30, 2017 (check here for the times as they vary) at the Annex at 823 Seymour St. From the Georgia Straight’s April 12, 2017 Arts notice,
“Mathematics is an art form in itself, as proven by Pi Theatre’s number-charged Long Division. This is a “refreshed remount” of Peter Dickinson’s ambitious work, one that circles around seven seemingly unrelated characters (including a high-school math teacher, a soccer-loving imam, and a lesbian bar owner) bound together by a single traumatic incident. Directed by Richard Wolfe, with choreography by Lesley Telford and musical score by Owen Belton, it’s a multimedia, movement-driven piece that has a strong cast. … “
You can read more about the production here. As far as I’m aware, there are no upcoming show dates.
There seems to be some sort of affinity between theatre and mathematics, I recently featured (January 3, 2020 posting) a theatrical piece by Hannah Moscovitch titled, ‘Infinity‘, about time, physics, math and more. It had its first production in Toronto in 2015.
John Mighton, a playwright and mathematician, wrote ‘The Little Years’ which has been produced in both Vancouver and Toronto. From a May 9, 2005 article by Kathleen Oliver for the Georgia Straight,
The Little Years is a little jewel of a play: small but multifaceted, and beautifully crafted.
John Mighton’s script gives us glimpses into different stages in the life of Kate, a woman whose early promise as a mathematician is cut short. At age 13, she’s a gifted student whose natural abilities are overlooked by 1950s society, which has difficulty conceiving of women as scientists. Instead, she’s sent to vocational school while her older brother, William, grows up to become one of the most widely praised poets of his generation.
John Mighton is a successful playwright and mathematician, yet at times in his life, he’s struggled with doubt. However, he also learned there was hope, and that’s the genesis of The Little Years, which opens at the Tarragon Theatre on Nov. 16 and runs to Dec. 16 .
In keeping (more or less) with this subsection’s theme ‘The Word’, Mighton has recently had a new book published, ‘All Things Being Equal: Why Math is the Key to a Better World’, according to a January 24, 2020 article (online version) by Jamie Portman for Postmedia,
It’s more than two decades since Canadian mathematician and playwright John Mighton found himself playing a small role in the film, Good Will Hunting. What he didn’t expect when he took on the job was that he would end up making a vital contribution to a screenplay that would go on to win an Oscar for its writers, Ben Affleck and Matt Damon.
What happened on that occasion tells you a great deal about Mighton’s commitment to the belief that society grossly underestimates the intellectual capacity of human beings — a belief reiterated with quiet eloquence in his latest book, All Things Being Equal.
Mighton loved the experience but as shooting continued he became troubled over his involvement in a movie that played “heavily on the idea that geniuses like Will are born and not made.” This was anathema to his own beliefs as a mathematician and he finally summoned up the courage to ask Affleck and Damon if he could write a few extra lines for his character. This speech was the result: “Most people never get the chance to see how brilliant they can be. They don’t find teachers who believe in them. They get convinced they’re stupid.”
At a time of growing controversy across Canada over the teaching of mathematics in school and continuing evidence of diminishing student results, Mighton continues to feel gratitude to the makers of Good Will Hunting for heeding his concerns. [I will be writing a post about the latest PISA scores where Canadian students have again slipped in their mathematics scores.]
Mighton is on the phone from from Toronto, his voice soft-spoken but still edged with fervour. He pursues two successful careers — as an award-winning Canadian playwright and as a renowned mathematician and philosopher who has devoted a lifetime to developing strategies that foster the intellectual potential of all children through learning math. But even as he talks about his 2001 founding of JUMP Math, a respected charity that offers a radical alternative to conventional teaching of the subject, he’s anxious to remind you that he’s a guy who almost failed calculus at university and who once struggled to overcome his “own massive math anxiety.”
You can find out more about John Mighton in his Wikipedia entry (mostly about his academic accomplishments) and on the JUMP Math website (better overall biography).
It’s called ‘Math Out Loud’ and was first mentioned here in a January 9, 2012 posting (the same post also featured the BIRS poetry workshop),
“When Mackenzie Gray talks about the way Paul McCartney used a recursive sequence to make the song “I Want You (She’s So Heavy)” seem to last forever, you realize that part of the Beatles’ phenomenal success might have sprung from McCartney’s genius as a mathematician.
When Roger Kemp draws on a napkin to illustrate that you just have to change the way you think about numbers to come up with a binary code for pi (as in 3.14 ad infinitum), you get a sense that math can actually be a lot of fun.”
Produced by MITACS which in 2012 was known as ‘Mathematics of Information Technology and Complex Systems’, a not-for-profit research organization, the musical went on tour in the Fall of 2012 (according to my September 7, 2012 posting). Unusually, I did not embed the promotional trailer for this 2012 musical so, here it is now,
Since 2012, Mitacs has gone through some sort of rebranding process and it’s now described as a nonprofit national research organization. For more you can read its Wikipedia entry or go to its website.
Acting and storytelling
It turns out there was an acting class (five sessions) for scientists at the University of Calgary in 2017. Here’s more from the course’s information sheet,
Act Your Science: Improve Your Communication Skills with Training in Improvisation 2 hours a session, 5 sessions, every Wednesday starting November 14  …
Dr. Jeff Dunn, Faculty of Graduate Studies, Graduate Students Association, the Canadian Science Writers Association [also known as Science Writers and Communicators of Canada] and the Loose Moose Theatre have teamed together to provide training in a skill which will be useful where ever your career takes you.
The goal of this project is to improve the science communication skills of graduate students in science fields. We will improve your communication through the art of training in improvisation. Training will help with speech and body awareness. Improvisation will provide life‐long skills in communication, in a fun interactive environment.
For many years, Alan Alda, a well-known actor (originally of the “MASH” television series fame), has applied his acting skills and improvisation training to help scientists improve their communication. He developed the Alan Alda Centre for Communicating Science at Stony Brook University.
The training will involve five 2hr improvisation workshop sessions led by one of Canada’s top professional improvisation trainers, Dennis Cahill, the Artistic Director from Loose Moose Theatre. Dennis has an international reputation for developing the theatrical style of improvisation. Training involves a lot of moving around (and possibly rolling on the floor!) so dress casually. Be prepared to release your inhibitions!
The information sheet includes a link to this University of Chicago video (posted on Youtube February 24, 2014) of actor Alan Alda discussing science communication,
Victoria Bouvier, a Michif-Metis woman, is of the Red River Settlement and Boggy Creek, Manitoba, and born and raised in Calgary. She is an Assistant professor in Indigenous Studies at Mount Royal University and a doctoral candidate in Educational Research [emphasis mine] at the University of Calgary. Her research is exploring how Michif/Métis people, born and raised in urban environments, practice and express their self-understandings, both individually and collectively through using an Indigenous oral system and visual media as methodology.
In a technology-laden society, people are capturing millions of photographs and videos that document their lived experiences, followed by uploading them to social media sites. As mass amounts of media is being shared each day, the question becomes: are we utilizing photos and videos to derive meaning from our everyday lived experiences, while settling in to a deeper sense of our self-in-relation?
This session will explore how photos and videos, positioned within an Indigenous oral system, are viewed and interacted with as a third perspective in the role of storytelling.
Finally, h/t to Jennifer Bon Bernard’s April 19, 2017 article (reposted Dec. 11, 2019) about Act Your Science for the Science Writers and Communicators blog. The original date doesn’t look right to me but perhaps she participated in a pilot project.
Neuroscience, science policy, and science advice
The end of this part is almost in sight
Knitting in Toronto and drawings in Vancouver (neuroscience)
In 2017, Toronto hosted a neuroscience event which combined storytelling and knitting (from my October 12, 2017 posting (Note: the portion below is an excerpt from an ArtSci Salon announcement),
With NARRATING NEUROSCIENCE we plan to initiate a discussion on the role and the use of storytelling and art (both in verbal and visual forms) to communicate abstract and complex concepts in neuroscience to very different audiences, ranging from fellow scientists, clinicians and patients, to social scientists and the general public. We invited four guests to share their research through case studies and experiences stemming directly from their research or from other practices they have adopted and incorporated into their research, where storytelling and the arts have played a crucial role not only in communicating cutting edge research in neuroscience, but also in developing and advancing it.
The ArtSci Salon folks also announced this (from the Sept. 25, 2017 ArtSci Salon announcement; received via email),
ATTENTION ARTSCI SALONISTAS AND FANS OF ART AND SCIENCE!! CALL FOR KNITTING AND CROCHET LOVERS!
In addition to being a PhD student at the University of Toronto, Tahani Baakdhah is a prolific knitter and crocheter and has been the motor behind two successful Knit-a-Neuron Toronto initiatives. We invite all Knitters and Crocheters among our ArtSci Salonistas to pick a pattern (link below) and knit a neuron (or 2! Or as many as you want!!)
BRING THEM TO OUR OCTOBER 20 ARTSCI SALON! Come to the ArtSci Salon and knit there!
That link to the patterns is still working.
Called “The Beautiful Brain” and held in the same time frame as Toronto’s neuro event, Vancouver hosted an exhibition of Santiago Ramon y Cajal’s drawings from September 5 to December 3, 2017. In concert with the exhibition, the local ‘neuro’ community held a number of outreach events. Here’s what I had in my September 11, 2017 posting where I quoted from the promotional material for the exhibition,
The Beautiful Brain is the first North American museum exhibition to present the extraordinary drawings of Santiago Ramón y Cajal (1852–1934), a Spanish pathologist, histologist and neuroscientist renowned for his discovery of neuron cells and their structure, for which he was awarded the Nobel Prize in Physiology and Medicine in 1906. Known as the father of modern neuroscience, Cajal was also an exceptional artist. He combined scientific and artistic skills to produce arresting drawings with extraordinary scientific and aesthetic qualities.
A century after their completion, Cajal’s drawings are still used in contemporary medical publications to illustrate important neuroscience principles, and continue to fascinate artists and visual art audiences. …

From Vancouver, the exhibition traveled to a gallery in New York City and then onto the Massachusetts Institute of Technology (MIT).
Mehrdad Hariri has done a an extraordinary job as its founder and chief executive officer. The CSPC has developed from a single annual conference to an organization that hosts different events throughout the year and publishes articles and opinion pieces on Canadian science policy and has been instrumental in the development of a Canadian science policy community.
The magnitude of Hariri’s accomplishment becomes clear when reading J.w. Grove’s [sic] article, Science Policy, in The Canadian Encyclopedia and seeing that the most recent reports on a national science policy seem to be the Science Council’s (now defunct) 4th report in 1968, Towards a National Science Policy in Canada, the OECD’s (Organization for Economic Cooperation and Development) 1969 Review of [Canada’s] Science Policy, and 3 reports from the Senate’s Lamontagne Committee (Special Committee on Science Policy). Grove’s article takes us only to 1988 but I have been unable to find any more recent reports focused on a national science policy for Canada. (If you have any information about a more recent report, please do let me know in the comments.)
A November 5, 2019 piece (#VoteScience: lessons learned and building science advocacy beyond the election cycle) on the CSPC website further illustrates how the Canadian science policy community has gained ground (Note: Links have been removed),
… on August 8, 2019, a coalition of Canadian science organizations and student groups came together to launch the #VoteScience campaign: a national, non-partisan effort to advocate for science in the federal elections, and make science an election issue.
Specifically, we — aka Evidence for Democracy, Science & Policy Exchange (SPE), and the Toronto Science Policy Network (TSPN) [emphases mine] — built a collection of tools and resources to empower Canadian scientists and science supporters to engage with their local candidates on science issues and the importance of evidence-informed decision-making. Our goal was to make it easy for as many Canadians as possible to engage with their candidates — and they did.
Over the past three months, our #VoteScience portal received over 3,600 visitors, including 600 visitors who used our email form to reach out directly to their local candidates. Collectively, we took #VoteScience selfies, distributed postcards to supporters across Canada, and even wrote postcards to every sitting Member of Parliament (in addition to candidates from all parties in each of our own ridings). Also of note, we distributed a science policy questionnaire to the federal parties, to help better inform Canadians about where the federal parties stand on relevant science issues, and received responses from all but one party. We’ve also advocated for science through various media outlets, including commenting for articles appearing in The Narwhal and Nature News, and penning op-eds for outlets such as the National Observer, University Affairs, Le Devoir, and Découvrir.
Prior to SPIN, the Council of Canadian Academies (CCA; more about them in part 4), issued a 2017 report titled, Science Policy: Considerations for Subnational Governments. The report was the outcome of a 2016 CCA workshop originally titled, Towards a Science Policy in Alberta. I gather the scope broadened.
Interesting trajectory, yes?
Chief Science advisors/scientists
In September 2017, the Canadian federal government announced that a Chief Science Advisor, Dr. Mona Nemer, had been appointed. I have more about the position and Dr. Nemer in my September 26, 2017 posting. (Prior to Dr. Nemer’s appointment a previous government had discontinued a National Science Advisor position that existed from 2004 to 2008.)
The Office of the Chief Science Advisor released it first annual report in 2019 and was covered here in a March 19, 2019 posting.
Québec is the only province (as far as I know) to have a Chief Scientist, Rémi Quirion who was appointed in 2011.
Onto Part 4 where you’ll find we’ve gone to the birds and more.
*The Canadian Science Policy Centre (CSPC) section was written sometime in February 2020. I believe they are planning to publish an editorial piece I submitted to them on April 20, 202 (in other words, before this post was published) in response to their call for submissions (see my April 1, 2020 post for details about the call). In short, I did not praise the organization with any intention of having my work published by them. (sigh) Awkward timing.
I have two stories about lungs and they are entirely different with the older one being a bioengineering story from the US and the more recent one being an artificial tissue story from the University of Toronto and the University of Ottawa (both in Canada).
Lab grown lungs
The Canadian Broadcasting Corporation’s Quirks and Quarks radio programme posted a December 29, 2018 news item (with embedded radio files) about bioengineered lunjgs,
There are two major components to building an organ: the structure and the right cells on that structure. A team led by Dr. Joan Nichols, a Professor of Internal Medicine, Microbiology and Immunology at the University of Texas Medical Branch in Galveston, were able to tackle both parts of the problem
In their experiment they used a donor organ for the structure. They took a lung from an unrelated pig, and stripped it of its cells, leaving a scaffold of collagen, a tough, flexible protein. This provided a pre-made appropriate structure, though in future they think it may be possible to use 3-D printing technology to get the same result.
They then added cultured cells from the animal who would be receiving the transplant – so the lung was made of the animal’s own cells. Cultured lung and blood vessel cells were placed on the scaffold and it was placed in a tank for 30 days with a cocktail of nutrients to help the cells stick to the scaffold and proliferate. The result was a kind of baby lung.
They then transplanted the bio-engineered, though immature, lung into the recipient animal where they hoped it would continue to develop and mature – growing to become a healthy, functioning organ.
The recipients of the bio-engineered lungs were four pigs adult pigs, which appeared to tolerate the transplants well. In order to study the development of the bio-engineered lungs, they euthanized the animals at different times: 10 hours, two weeks, one month and two months after transplantation.
They found that as early as two weeks, the bio-engineered lung had integrated into the recipient animals’ body, building a strong network of blood vessels essential for the lung to survive. There was no evidence of pulmonary edema, the build of fluid in the lungs, which is usually a sign of the blood vessels not working efficiently. There was no sign of rejection of the transplanted organs, and the pigs were healthy up to the point where they were euthanized.
One lingering concern is how well the bio-engineered lungs delivered oxygen. The four pigs who received the trasplant [sic] had one original functioning lung, so they didn’t depend on their new bio-engineered lung for breathing. The scientists were not sure that the bio-engineered lung was mature enough to handle the full load of oxygen on its own.
You can hear Bob McDonald’s (host of Quirks & Quarks, a Canadian Broadcasting Corporation science radio programme) interview lead scientist, Dr. Joan Nichols if you go to here. (Note: I find he overmodulates his voice but some may find he has a ‘friendly’ voice.)
This is an image of the lung scaffold produced by the team,
In 2014, Joan Nichols and Joaquin Cortiella from The University of Texas Medical Branch at Galveston were the first research team to successfully bioengineer human lungs in a lab. In a paper now available in Science Translational Medicine, they provide details of how their work has progressed from 2014 to the point no complications have occurred in the pigs as part of standard preclinical testing.
“The number of people who have developed severe lung injuries has increased worldwide, while the number of available transplantable organs have decreased,” said Cortiella, professor of pediatric anesthesia. “Our ultimate goal is to eventually provide new options for the many people awaiting a transplant,” said Nichols, professor of internal medicine and associate director of the Galveston National Laboratory at UTMB.
To produce a bioengineered lung, a support scaffold is needed that meets the structural needs of a lung. A support scaffold was created using a lung from an unrelated animal that was treated using a special mixture of sugar and detergent to eliminate all cells and blood in the lung, leaving only the scaffolding proteins or skeleton of the lung behind. This is a lung-shaped scaffold made totally from lung proteins.
The cells used to produce each bioengineered lung came from a single lung removed from each of the study animals. This was the source of the cells used to produce a tissue-matched bioengineered lung for each animal in the study. The lung scaffold was placed into a tank filled with a carefully blended cocktail of nutrients and the animals’ own cells were added to the scaffold following a carefully designed protocol or recipe. The bioengineered lungs were grown in a bioreactor for 30 days prior to transplantation. Animal recipients were survived for 10 hours, two weeks, one month and two months after transplantation, allowing the research team to examine development of the lung tissue following transplantation and how the bioengineered lung would integrate with the body.
All of the pigs that received a bioengineered lung stayed healthy. As early as two weeks post-transplant, the bioengineered lung had established the strong network of blood vessels needed for the lung to survive.
“We saw no signs of pulmonary edema, which is usually a sign of the vasculature not being mature enough,” said Nichols and Cortiella. “The bioengineered lungs continued to develop post-transplant without any infusions of growth factors, the body provided all of the building blocks that the new lungs needed.”
Nichols said that the focus of the study was to learn how well the bioengineered lung adapted and continued to mature within a large, living body. They didn’t evaluate how much the bioengineered lung provided oxygenation to the animal.
“We do know that the animals had 100 percent oxygen saturation, as they had one normal functioning lung,” said Cortiella. “Even after two months, the bioengineered lung was not yet mature enough for us to stop the animal from breathing on the normal lung and switch to just the bioengineered lung.”
For this reason, future studies will look at long-term survival and maturation of the tissues as well as gas exchange capability.
The researchers said that with enough funding, they could grow lungs to transplant into people in compassionate use circumstances within five to 10 years.
“It has taken a lot of heart and 15 years of research to get us this far, our team has done something incredible with a ridiculously small budget and an amazingly dedicated group of people,” Nichols and Cortiella said.

Artificial lung cancer tissue
The research teams at the University of Toronto and the University of Ottawa worked on creating artificial lung tissue but other applications are possible too. First, there’s the announcement in a February 25, 2019 news item on phys.org,
A 3-D hydrogel created by researchers in U of T Engineering Professor Molly Shoichet’s lab is helping University of Ottawa researchers to quickly screen hundreds of potential drugs for their ability to fight highly invasive cancers.
Cell invasion is a critical hallmark of metastatic cancers, such as certain types of lung and brain cancer. Fighting these cancers requires therapies that can both kill cancer cells as well as prevent cell invasion of healthy tissue. Today, most cancer drugs are only screened for their ability to kill cancer cells.
“In highly invasive diseases, there is a crucial need to screen for both of these functions,” says Shoichet. “We now have a way to do this.”
In their latest research, the team used hydrogels to mimic the environment of lung cancer, selectively allowing cancer cells, and not healthy cells, to invade. In their latest research, the team used hydrogels to mimic the environment of lung cancer, selectively allowing cancer cells, and not healthy cells, to invade. This emulated environment enabled their collaborators in Professor Bill Stanford’s lab at University of Ottawa to screen for both cancer-cell growth and invasion. The study, led by Roger Y. Tam, a research associate in Shochet’s lab, was recently published in Advanced Materials.
“We can conduct this in a 384-well plate, which is no bigger than your hand. And with image-analysis software, we can automate this method to enable quick, targeted screenings for hundreds of potential cancer treatments,” says Shoichet.
One example is the researchers’ drug screening for lymphangioleiomyomatosis (LAM), a rare lung disease affecting women. Shoichet and her team were inspired by the work of Green Eggs and LAM, a Toronto-based organization raising awareness of the disease.
Using their hydrogels, they were able to automate and screen more than 800 drugs, thereby uncovering treatments that could target disease growth and invasion.
In the ongoing collaboration, the researchers plan to next screen multiple drugs at different doses to gain greater insight into new treatment methods for LAM. The strategies and insights they gain could also help identify new drugs for other invasive cancers.
Shoichet, who was recently named a Distinguished Woman in Chemistry or Chemical Engineering, also plans to patent the hydrogel technology.
“This has, and continues to be, a great collaboration that is advancing knowledge at the intersection of engineering and biology,” says Shoichet.
I note that Shoichet (pronounced ShoyKet) is getting ready to patent this work. I do have a question about this and it’s not up to Shoichet to answer as she didn’t create the system. Will the taxpayers who funded her work receive any financial benefits should the hydrogel prove to be successful or will we be paying double, both supporting her research and paying for the hydrogel through our healthcare costs?
Getting back to the research, here’s a link to and a citation for the paper,
It seems May 2019 is destined to be a big month where science events in Canada are concerned. I have three national science science promotion programmes, Science Odyssey, Science Rendezvous, and Pint of Science Festival Canada (part of an international effort); two local (Vancouver, Canada) events, an art/sci café from Curiosity Collider and a SciCats science communication workshop; a national/local event at Ingenium’s Canada Science and Technology Museum in Ottawa, and an international social media (Twitter) event called #Museum Week.
Science Odyssey 2019 (formerly Science and Technology Week)
In 2016 the federal Liberal government rebranded a longstanding science promotion/education programme known as Science and Technology Week to Science Odyseey and moved it from the autumn to the spring. (Should you be curious about this change, there’s a video on YouTube with Minister of Science Kirsty Duncan and Parliamentary Secretary for Science Terry Beech launching “Science Odyssey, 10 days of innovation and science discovery.” My May 10, 2016 posting provides more details about the change.)
Moving forward to the present day, the 2019 edition of Science Odyseey will run from May 4 – May 19, 2019 for a whopping16 days. The Science Odyssey website can be found here.
Once you get to the website and choose your language, on the page where you land, you’ll find if you scroll down, there’s an option to choose a location (ignore the map until after you’ve successfully chosen a location and clicked on the filter button (it took me at least twice before achieving success; this seems to be a hit and miss affair).
Once you have applied the filter, the map will change and make more sense but I liked using the text list which appears after the filter has been applied better. Should you click on the map, you will lose the filtered text list and have to start over.
Science Rendezvous 2019
I’m not sure I’d call Science Rendezvous the largest science festival in Canada (it seems to me Beakerhead might have a chance at that title) but it did start in 2008 as its Wikipedia entry mentions (Note: Links have been removed),
Science Rendezvous is the largest [emphasis mine] science festival in Canada; its inaugural event happened across the Greater Toronto Area (GTA) on Saturday, May 10, 2008. By 2011 the event had gone national, with participation from research institutes, universities, science groups and the public from all across Canada – from Vancouver to St. John’s to Inuvik. Science Rendezvous is a registered not-for-profit organization dedicated to making great science accessible to the public. The 2017 event took place on Saturday May 13 at more than 40 simultaneous venues.
This free all-day event aims to highlight and promote great science in Canada. The target audience is the general public, parents, children and youth, with an ultimate aim of improving enrollment and investment in sciences and technology in the future.
Science Rendezvous is being held on May 11, 2019 and its website can be found here.You can find events listed by province here. There are no entries for Alberta, Nunavut, or Prince Edward Island this year.
Science Rendezvous seems to have a relationship to Science Odyssey, my guess is that they are receiving funds. In any case , you may find that an event on the Science Rendezvous site is also on the Science Odyssey site or vice versa, depending on where you start.
Pint of Science Festival (Canada)
The 2019 Pint of Science Festival will be in 25 cities across Canada from May 20 – 22, 2019. Reminiscent of the Café Scientifique events (Vancouver, Canada) where science and beer are closely interlinked, so it is with the Pint of Science Festival, which has its roots in the UK. (Later, I have something about Guelph, Ontario and its ‘beery’ 2019 Pint event.)
Here’s some history about the Canadian inception and its UK progenitor. From he Pint of Science of Festival Canada website, the About Us page,
About Us Pint of Science is a non-profit organisation that brings some of the most brilliant scientists to your local pub to discuss their latest research and findings with you. You don’t need any prior knowledge, and this is your chance to meet the people responsible for the future of science (and have a pint with them). Our festival runs over a few days in May every year,but we occasionally run events during other months.
A propos de nous Pinte de Science est une organisation à but non lucratif qui amène quelques brillants scientifiques dans un bar près de chez vous pour discuter de leurs dernières recherches et découvertes avec le public. Vous n’avez besoin d’aucune connaissance préalable, et c’est l’occasion de rencontrer les responsables de l’avenir de la science (et de prendre une pinte avec eux). Notre festival se déroule sur quelques jours au mois de mai chaque année, mais nous organisons parfois quelques événements exceptionnels en dehors des dates officielles du festival.
History In 2012 Dr Michael Motskin and Dr Praveen Paul were two research scientists at Imperial College London in the UK. They started and organised an event called ‘Meet the Researchers’. It brought people affected by Parkinson’s, Alzheimer’s, motor neurone disease and multiple sclerosis into their labs to show them the kind of research they do. It was inspirational for both visitors and researchers. They thought if people want to come into labs to meet scientists, why not bring the scientists out to the people? And so Pint of Science was born. In May 2013 they held the first Pint of Science festival in just three UK cities. It quickly took off around the world and is now in nearly 300 cities. Read more here. Pint of Science Canada held its first events in 2016, a full list of locations can be found here.
L’Histoire En 2012, Dr Michael Motskin et Dr Praveen Paul étaient deux chercheurs à l’Imperial College London, au Royaume-Uni. Ils ont organisé un événement intitulé «Rencontrez les chercheurs» et ont amené les personnes atteintes de la maladie de Parkinson, d’Alzheimer, de neuropathie motrice et de sclérose en plaques dans leurs laboratoires pour leur montrer le type de recherche qu’ils menaient. C’était une source d’inspiration pour les visiteurs et les chercheurs. Ils ont pensé que si les gens voulaient se rendre dans les laboratoires pour rencontrer des scientifiques, pourquoi ne pas les faire venir dans des bars? Et ainsi est née une Pinte de Science. En mai 2013, ils ont organisé le premier festival Pinte de Science dans trois villes britanniques. Le festival a rapidement décollé dans le monde entier et se trouve maintenant dans près de 300 villes. Lire la suite ici . Pinte de Science Canada a organisé ses premiers événements en 2016. Vous trouverez une liste complète des lieux ici.
I clicked on ‘Vancouver’ and found a range of bars, dates, and topics. It’s worth checking out every topic because the title doesn’t necessarily get the whole story across. Kudos to the team putting this together. Where these things are concderned, I don’t get surprised often. Here’s how it happened, I was expecting another space travel story when I saw this title: ‘Above and beyond: planetary science’. After clicking on the arrow,
Geology isn’t just about the Earth beneath our feet. Join us for an evening out of this world to discover what we know about the lumps of rock above our heads too!
Thank you for the geology surprise. As for the international part of this festival, you can find at least one bar in Europe, Asia and Australasia, the Americas, and Africa.
Beer and Guelph (Ontario)
I also have to tip my hat to Science Borealis (Canada’s science blog aggregator) for the tweet which led me to Pint of Science Guelph and a very special beer/science ffestival announcement,
Pint of Science Guelph will be held over three nights (May 20, 21, and 22) at six different venues, and will feature twelve different speakers. Each venue will host two speakers with talks ranging from bridging the digital divide to food fraud to the science of bubbles and beer. There will also be trivia and lots of opportunity to chat with the various researchers to learn more about what they do, and why they do it.
But wait! There’s more! Pint of Science Guelph is (as far as I’m aware) the first Pint of Science (2019) in Canada to have its own beer. Thanks to the awesome folks at Wellington Brewery, a small team of Pint of Science Guelph volunteers and speakers spent last Friday at the brewery learning about the brewing process by making a Brut IPA. This tasty beverage will be available as part of the Pint of Science celebration. Just order it by name – Brain Storm IPA.
The event starts promptly at 8pm (doors open at 7:30pm). $5.00-10.00 (sliding scale) cover at the door. Proceeds will be used to cover the cost of running this event, and to fund future Curiosity Collider events. Curiosity Collider is a registered BC non-profit organization.
SciCATs (Science Communication Action Team, uh, something) is a collective of science communicators (and cat fans) providing free, open source, online, skills-based science communication training, resources, and in-person workshops.
We believe that anyone, anywhere should be able to learn the why and the how of science communication!
For the past two years, SciCATs has been developing online resources and delivering science communication workshops to diverse groups of those interested in science communication. We are now hosting an open, public event to help a broader audience of those passionate about science to mix, mingle, and build their science communication skills – all while having fun.
SciCATs’ Fundamentals of Science Communication is a three-hour interactive workshop [emphasis mine] followed by one hour of networking.
For this event, our experienced SciCATs facilitators will lead the audience through our most-requested science communication modules: Why communicate science Finding your message Telling your science as a story Understanding your audience [emphasis mine]
This workshop is ideal for people who are new to science communication [empahsis mine] or those who are more experienced. You might be an undergraduate or graduate student, researcher, technician, or other roles that have an interest in talking to the public about what you do. Perhaps you just want to hang out and meet some local science communicators. This is a great place to do it!
After the workshop we have a reservation at Chaqui Grill (1955 Cornwall), it will be a great opportunity to continue to network with all of the Sci-Cats and science communicators that attend over a beverage! They do have a full dinner menu as well.
Date and Time Sun, May 5, 2019 2:00 PM – 5:00 PM PDT
Location H.R. MacMillan Space Centre 1100 Chestnut Street Vancouver, BC V6J 3J9
Refund Policy Refunds up to 1 day before event

#Museum Week 2019
#Museum Week (website) is being billed as “The first worldwide cultural event on social networks. The latest edition is being held from May 13 – 19, 2019. As far as I’m aware, it’s held on Twitter exclusively. You can check out the hash tag feed (#Museum Week) as it’s getting quite active even now.
They don’t have a list of participants for this year which leaves me feeling a little sad. It’s kind of fun to check out how many and which institutions in your country are planning to participate. I would have liked to have seen whether or not the Canada Science and Technology Museum and Science World Vancouver will be there. (I think both participated last year.) Given how busy the hash tag feed becomes during the event, I’m not likely to see them on it even if they’re tweeting madly.
May 2019 looks to be a very busy month for Canadian science enthusiasts! No matter where you are there is something for you.
In a recent (Tuesday, March 6, 2018) live stream ‘conversation’ (‘Science in Canada; Investing in Canadian Innovation’ now published on YouTube) between Canadian Prime Minister, Justin Trudeau, and US science communicator, Bill Nye, at the University of Ottawa, they discussed, amongst many other topics, what AI (artificial intelligence) can and can’t do. They seemed to agree that AI can’t be creative, i.e., write poetry, create works of art, make jokes, etc. A conclusion which is both (in my opinion) true and not true.
There are times when I think the joke may be on us (humans). Take for example this March 6, 2018 story by Alexis Madrigal for The Atlantic magazine (Note: Links have been removed),
SkyKnit: How an AI Took Over an Adult Knitting Community
Ribald knitters teamed up with a neural-network creator to generate new types of tentacled, cozy shapes.
Janelle Shane is a humorist [Note: She describes herself as a “Research Scientist in optics. Plays with neural networks. …” in her Twitter bio.] who creates and mines her material from neural networks, the form of machine learning that has come to dominate the field of artificial intelligence over the last half-decade.
Perhaps you’ve seen the candy-heart slogans she generated for Valentine’s Day: DEAR ME, MY MY, LOVE BOT, CUTE KISS, MY BEAR, and LOVE BUN.
Or her new paint-color names: Parp Green, Shy Bather, Farty Red, and Bull Cream.
Or her neural-net-generated Halloween costumes: Punk Tree, Disco Monster, Spartan Gandalf, Starfleet Shark, and A Masked Box.
Her latest project, still ongoing, pushes the joke into a new, physical realm. Prodded by a knitter on the knitting forum Ravelry, Shane trained a type of neural network on a series of over 500 sets of knitting instructions. Then, she generated new instructions, which members of the Ravelry community have actually attempted to knit.
“The knitting project has been a particularly fun one so far just because it ended up being a dialogue between this computer program and these knitters that went over my head in a lot of ways,” Shane told me. “The computer would spit out a whole bunch of instructions that I couldn’t read and the knitters would say, this is the funniest thing I’ve ever read.”
It appears that the project evolved,
The human-machine collaboration created configurations of yarn that you probably wouldn’t give to your in-laws for Christmas, but they were interesting. The user citikas was the first to post a try at one of the earliest patterns, “reverss shawl.” It was strange, but it did have some charisma.
Shane nicknamed the whole effort “Project Hilarious Disaster.” The community called it SkyKnit.
I’m not sure what’s meant by “community” as mentioned in the previous excerpt. Are we talking about humans only, AI only, or both humans and AI?
Here’s some of what underlies Skyknit (Note: Links have been removed),
The different networks all attempt to model the data they’ve been fed by tuning a vast, funky flowchart. After you’ve created a statistical model that describes your real data, you can also roll the dice and generate new, never-before-seen data of the same kind.
How this works—like, the math behind it—is very hard to visualize because values inside the model can have hundreds of dimensions and we are humble three-dimensional creatures moving through time. But as the neural-network enthusiast Robin Sloan puts it, “So what? It turns out imaginary spaces are useful even if you can’t, in fact, imagine them.”
Out of that ferment, a new kind of art has emerged. Its practitioners use neural networks not to attain practical results, but to see what’s lurking in the these vast, opaque systems. What did the machines learn about the world as they attempted to understand the data they’d been fed? Famously, Google released DeepDream, which produced trippy visualizations that also demonstrated how that type of neural network processed the textures and objects in its source imagery.
Madrigal’s article is well worth reading if you have the time. You can also supplement Madrigal’s piece with an August 9, 2017 article about Janelle Shane’s algorithmic experiments by Jacob Brogan for slate.com.

SkyKnit is a type of machine learning algorithm called an artificial neural network. Its creator, Janelle Shane of AIweirdness.com, gave it 88,000 lines of knitting instructions from Stitch-Maps.com and Ravelry, and it taught itself how to make new patterns. Join the discussion!
SkyKnit seems to have created something that has paralell columns, and is reversible. Perhaps a scarf?

If you’ve been on the internet today, you’ve probably interacted with a neural network. They’re a type of machine learning algorithm that’s used for everything from language translation to finance modeling. One of their specialties is image recognition. Several companies – including Google, Microsoft, IBM, and Facebook – have their own algorithms for labeling photos. But image recognition algorithms can make really bizarre mistakes.
Microsoft Azure’s computer vision API [application programming interface] added the above caption and tags. But there are no sheep in the image of above. None. I zoomed all the way in and inspected every speck.
I have become quite interested in Shane’s self descriptions such as this one from the aiweirdness.com website,
I train neural networks, a type of machine learning algorithm, to write unintentional humor as they struggle to imitate human datasets. Well, I intend the humor. The neural networks are just doing their best to understand what’s going on. Currently located on the occupied land of the Arapahoe Nation.
As for the joke being on us, I can’t help remembering the Facebook bots that developed their own language (Facebotlish), and were featured in my June 30, 2017 posting, There’s a certain eerieness to it all, which seems an appropriate response in a year celebrating the 200th anniversary of Mary Shelley’s 1818 book, Frankenstein; or, the Modern Prometheus. I’m closing with a video clip from the 1931 movie,

Takeaways and recommendations:
The opportunity for Canada
The potential impact of artificial intelligence (AI) could be as significant as the industrial revolution of the 19th century.
Canada’s global advantage in deep learning (a subset of machine learning) stems from the pioneering work of Geoffrey Hinton and early support from CIFAR and NSERC.
AI could mark a turning point in Canada’s innovation performance, fueled by the highest levels of venture capital financing in nearly a decade, and underpinned by publicly funded research at the federal, provincial and institutional levels.
The Canadian AI advantage can only be fully realized by developing and importing skilled talent, accessible markets, capital and companies willing to adopt new technologies into existing industries.
Canada leads in the combination of functional genomics and machine learning which is proving effective for predicting the functional variation in genomes.
AI promises advances in biomedical engineering by connecting chronic diseases – the largest health burden in Canada – to gene regulatory networks by understanding how stem cells make decisions.
AI can be effectively deployed to evaluate health and health systems in the general population.
AI brings potential ethical and economic perils and requires a watchdog to oversee standards, engage in fact-based debate and prepare for the potential backlash over job losses to robots.
The ethical, environmental, economic, legal and social (GEL3S) aspects of genomics have been largely marginalized and it’s important not to make the same mistake with AI.
AI’s rapid scientific development makes it difficult to keep pace with safeguards and standards.
The fields of AI’s and pattern recognition are strongly connected but here is room for improvement.
Self-learning algorithms such as Alphaville could lead to the invention of new things that humans currently don’t know how to do. The field is developing rapidly, leading to some concern over the deployment of such systems.
Training future AI professionals
Young researchers must be given the oxygen to excel at AI if its potential is to be realized.
Students appreciate the breadth of training and additional resources they receive from researchers with ties to both academia and industry.
The importance of continuing fundamental research in AI is being challenged by companies such as Facebook, Google and Amazon which are hiring away key talent.
The explosion of AI is a powerful illustration of how the importance of fundamental research may only be recognized and exploited after 20 or 30 years. As a result, support for fundamental research, and the students working in areas related to AI, must continue.

In fact, all of the institutions are in southern Ontario, even, the oddly named Science North.
I know from bitter experience it’s hard to put together panels but couldn’t someone from another province have participated?
Ah well, here’s hoping for 2018 and for a new location. After Ottawa as the CSPC site for three years in a row, please don’t make it a fourth year in a row.
Thanks to the Canadian Science Policy Centre’s September 26, 2017 announcement (received via email) a burning question has been answered,
After great anticipation, Prime Minister Trudeau along with Minister Duncan have announced Canada’s Chief Science Advisor, Dr. Mona Nemer, [emphasis mine] at a ceremony at the House of Commons. The Canadian Science Policy Centre welcomes this exciting news and congratulates Dr. Nemer on her appointment in this role and we wish her the best in carrying out her duties in this esteemed position. CSPC is looking forward to working closely with Dr. Nemer for the Canadian science policy community. Mehrdad Hariri, CEO & President of the CSPC, stated, “Today’s historic announcement is excellent news for science in Canada, for informed policy-making and for all Canadians. We look forward to working closely with the new Chief Science Advisor.”
In fulfilling our commitment to keep the community up to date and informed regarding science, technology, and innovation policy issues, CSPC has been compiling all news, publications, and editorials in recognition of the importance of the Federal Chief Science Officer as it has been developing, as you may see by clicking here.
The Government of Canada is committed to strengthen science in government decision-making and to support scientists’ vital work.
In keeping with these commitments, the Prime Minister, Justin Trudeau, today announced Dr. Mona Nemer as Canada’s new Chief Science Advisor, following an open, transparent, and merit-based selection process.
We know Canadians value science. As the new Chief Science Advisor, Dr. Nemer will help promote science and its real benefits for Canadians—new knowledge, novel technologies, and advanced skills for future jobs. These breakthroughs and new opportunities form an essential part of the Government’s strategy to secure a better future for Canadian families and to grow Canada’s middle class.
Dr. Nemer is a distinguished medical researcher whose focus has been on the heart, particularly on the mechanisms of heart failure and congenital heart diseases. In addition to publishing over 200 scholarly articles, her research has led to new diagnostic tests for heart failure and the genetics of cardiac birth defects. Dr. Nemer has spent more than ten years as the Vice-President, Research at the University of Ottawa, has served on many national and international scientific advisory boards, and is a Fellow of the Royal Society of Canada, a Member of the Order of Canada, and a Chevalier de l’Ordre du Québec.
As Canada’s new top scientist, Dr. Nemer will provide impartial scientific advice to the Prime Minister and the Minister of Science. She will also make recommendations to help ensure that government science is fully available and accessible to the public, and that federal scientists remain free to speak about their work. Once a year, she will submit a report about the state of federal government science in Canada to the Prime Minister and the Minister of Science, which will also be made public.
“We have taken great strides to fulfill our promise to restore science as a pillar of government decision-making. Today, we took another big step forward by announcing Dr. Mona Nemer as our Chief Science Advisor. Dr. Nemer brings a wealth of expertise to the role. Her advice will be invaluable and inform decisions made at the highest levels. I look forward to working with her to promote a culture of scientific excellence in Canada.” — The Rt. Hon. Justin Trudeau, Prime Minister of Canada
“A respect for science and for Canada’s remarkable scientists is a core value for our government. I look forward to working with Dr. Nemer, Canada’s new Chief Science Advisor, who will provide us with the evidence we need to make decisions about what matters most to Canadians: their health and safety, their families and communities, their jobs, environment and future prosperity.”
— The Honourable Kirsty Duncan, Minister of Science
“I am honoured and excited to be Canada’s Chief Science Advisor. I am very pleased to be representing Canadian science and research – work that plays a crucial role in protecting and improving the lives of people everywhere. I look forward to advising the Prime Minister and the Minister of Science and working with the science community, policy makers, and the public to make science part of government policy making.”
— Dr. Mona Nemer, Chief Science Advisor, Canada
Dr. Nemer is also a Knight of the Order of Merit of the French Republic, and has been awarded honorary doctorates from universities in France and Finland.
The Office of the Chief Science Advisor will be housed at Innovation, Science and Economic Development and supported by a secretariat.
Nemers’ Wikipedia entry does not provide much additional information although you can find out a bit more on her University of Ottawa page. Brian Owens in a Sept. 26, 2017 article for the American Association for the Advancement of Science’s (AAAS) Science Magazine provides a bit more detail, about this newly created office and its budget
Nemer’s office will have a $2 million budget, and she will report to both Trudeau and science minister Kirsty Duncan. Her mandate includes providing scientific advice to government ministers, helping keep government-funded science accessible to the public, and protecting government scientists from being muzzled.
Ivan Semeniuk’s Sept. 26, 2017 article for the Globe and Mail newspaper about Nemer’s appointment is the most informative (that I’ve been able to find),
Mona Nemer, a specialist in the genetics of heart disease and a long time vice-president of research at the University of Ottawa, has been named Canada’s new chief science advisor.
The appointment, announced Tuesday [Sept. 26, 2017] by Prime Minister Justin Trudeau, comes two years after the federal Liberals pledged to reinstate the position during the last election campaign and nearly a decade after the previous version of the role was cut by then prime minister Stephen Harper.
Dr. Nemer steps into the job of advising the federal government on science-related policy at a crucial time. Following a landmark review of Canada’s research landscape [Naylor report] released last spring, university-based scientists are lobbying hard for Ottawa to significantly boost science funding, one of the report’s key recommendations. At the same time, scientists and science-advocacy groups are increasingly scrutinizing federal actions on a range of sensitive environment and health-related issues to ensure the Trudeau government is making good on promises to embrace evidence-based decision making.
A key test of the position’s relevance for many observers will be the extent to which Dr. Nemer is able to speak her mind on matters where science may run afoul of political expediency.
Born in 1957, Dr. Nemer grew up in Lebanon and pursued an early passion for chemistry at a time and place where women were typically discouraged from entering scientific fields. With Lebanon’s civil war making it increasingly difficult for her to pursue her studies, her family was able to arrange for her to move to the United States, where she completed an undergraduate degree at Wichita State University in Kansas.
A key turning point came in the summer of 1977 when Dr. Nemer took a trip with friends to Montreal. She quickly fell for the city and, in short order, managed to secure acceptance to McGill University, where she received a PhD in 1982. …
It took a lot of searching to find out that Nemer was born in Lebanon and went to the United States first. A lot of immigrants and their families view Canada as a second choice and Nemer and her family would appear to have followed that pattern. It’s widely believed (amongst Canadians too) that the US is where you go for social mobility. I’m not sure if this is still the case but at one point in the 1980s Israel ranked as having the greatest social mobility in the world. Canada came in second while the US wasn’t even third or fourth ranked.
It’s the second major appointment by Justin Trudeau in the last few months to feature a woman who speaks French. The first was Julie Payette, former astronaut and Québecker, as the upcoming Governor General (there’s more detail and a whiff of sad scandal in this Aug. 21, 2017 Canadian Broadcasting Corporation online news item). Now there’s Dr. Mona Nemer who’s lived both in Québec and Ontario. Trudeau and his feminism, eh? Also, his desire to keep Québeckers happy (more or less).
I’m not surprised by the fact that Nemer has been based in Ottawa for several years. I guess they want someone who’s comfortable with the government apparatus although I for one think a little fresh air might be welcome. After all, the Minister of Science, Kirsty Duncan, is from Toronto which between Nemer and Duncan gives us the age-old Canadian government trifecta (geographically speaking), Ottawa-Montréal-Toronto.
Two final comments, I am surprised that Duncan did not make the announcement. After all, it was in her 2015 mandate letter.But perhaps Paul Wells in his acerbic June 29, 2017 article for Macleans hints at the reason as he discusses the Naylor report (review of fundamental science mentioned in Semeniuk’s article and for which Nemer is expected to provide advice),
The Naylor report represents Canadian research scientists’ side of a power struggle. The struggle has been continuing since Jean Chrétien left office. After early cuts, he presided for years over very large increases to the budgets of the main science granting councils. But since 2003, governments have preferred to put new funding dollars to targeted projects in applied sciences. …
Naylor wants that trend reversed, quickly. He is supported in that call by a frankly astonishingly broad coalition of university administrators and working researchers, who until his report were more often at odds. So you have the group representing Canada’s 15 largest research universities and the group representing all universities and a new group representing early-career researchers and, as far as I can tell, every Canadian scientist on Twitter. All backing Naylor. All fundamentally concerned that new money for research is of no particular interest if it does not back the best science as chosen by scientists, through peer review.
The competing model, the one preferred by governments of all stripes, might best be called superclusters. Very large investments into very large projects with loosely defined scientific objectives, whose real goal is to retain decorated veteran scientists and to improve the Canadian high-tech industry. Vast and sprawling labs and tech incubators, cabinet ministers nodding gravely as world leaders in sexy trendy fields sketch the golden path to Jobs of Tomorrow.
You see the imbalance. On one side, ribbons to cut. On the other, nerds experimenting on tapeworms. Kirsty Duncan, a shaky political performer, transparently a junior minister to the supercluster guy, with no deputy minister or department reporting to her, is in a structurally weak position: her title suggests she’s science’s emissary to the government, but she is not equipped to be anything more than government’s emissary to science.
Second, our other science minister, Navdeep Bains, Minister of Innovation, Science and Economic Development does not appear to have been present at the announcement. Quite surprising given where her office will located (from the government’s Sept. 26, 2017 press release in Quick Facts section ) “The Office of the Chief Science Advisor will be housed at Innovation, Science and Economic Development and supported by a secretariat.”
Finally, Wells’ article is well worth reading in its entirety and for those who are information gluttons, I have a three part series on the Naylor report, published June 8, 2017,
For the first time, researchers have sent a quantum-secured message containing more than one bit of information per photon through the air above a city. The demonstration showed that it could one day be practical to use high-capacity, free-space quantum communication to create a highly secure link between ground-based networks and satellites, a requirement for creating a global quantum encryption network.
Quantum encryption uses photons to encode information in the form of quantum bits. In its simplest form, known as 2D encryption, each photon encodes one bit: either a one or a zero. Scientists have shown that a single photon can encode even more information—a concept known as high-dimensional quantum encryption—but until now this has never been demonstrated with free-space optical communication in real-world conditions. With eight bits necessary to encode just one letter, for example, packing more information into each photon would significantly speed up data transmission.
This looks like donuts on a stick to me,

An Aug. 24, 2017 Optical Society news release (also on EurekAlert), which originated the news item, describes the work done by a team in Ottawa, Canada, (Note: The ‘Congratulate China’ piece (August 22, 2017 posting) includes excerpts from an article that gave a brief survey of various national teams [including Canada] working on quantum communication networks; Links have been removed),
“Our work is the first to send messages in a secure manner using high-dimensional quantum encryption in realistic city conditions, including turbulence,” said research team lead, Ebrahim Karimi, University of Ottawa, Canada. “The secure, free-space communication scheme we demonstrated could potentially link Earth with satellites, securely connect places where it is too expensive to install fiber, or be used for encrypted communication with a moving object, such as an airplane.”

As detailed in Optica, The Optical Society’s journal for high impact research, the researchers demonstrated 4D quantum encryption over a free-space optical network spanning two buildings 0.3 kilometers apart at the University of Ottawa. This high-dimensional encryption scheme is referred to as 4D because each photon encodes two bits of information, which provides the four possibilities of 01, 10, 00 or 11.
In addition to sending more information per photon, high-dimensional quantum encryption can also tolerate more signal-obscuring noise before the transmission becomes unsecure. Noise can arise from turbulent air, failed electronics, detectors that don’t work properly and from attempts to intercept the data. “This higher noise threshold means that when 2D quantum encryption fails, you can try to implement 4D because it, in principle, is more secure and more noise resistant,” said Karimi.
Using light for encryption
Today, mathematical algorithms are used to encrypt text messages, banking transactions and health information. Intercepting these encrypted messages requires figuring out the exact algorithm used to encrypt a given piece of data, a feat that is difficult now but that is expected to become easier in the next decade or so as computers become more powerful.
Given the expectation that current algorithms may not work as well in the future, more attention is being given to stronger encryption techniques such as quantum key distribution, which uses properties of light particles known as quantum states to encode and send the key needed to decrypt encoded data.
Although wired and free-space quantum encryption has been deployed on some small, local networks, implementing it globally will require sending encrypted messages between ground-based stations and the satellite-based quantum communication networks that would link cities and countries. Horizontal tests through the air can be used to simulate sending signals to satellites, with about three horizontal kilometers being roughly equal to sending the signal through the Earth’s atmosphere to a satellite.
Before trying a three-kilometer test, the researchers wanted to see if it was even possible to perform 4D quantum encryption outside. This was thought to be so challenging that some other scientists in the field said that the experiment would not work. One of the primary problems faced during any free-space experiment is dealing with air turbulence, which distorts the optical signal.
For the tests, the researchers brought their laboratory optical setups to two different rooftops and covered them with wooden boxes to provide some protection from the elements. After much trial and error, they successfully sent messages secured with 4D quantum encryption over their intracity link. The messages exhibited an error rate of 11 percent, below the 19 percent threshold needed to maintain a secure connection. They also compared 4D encryption with 2D, finding that, after error correction, they could transmit 1.6 times more information per photon with 4D quantum encryption, even with turbulence.
“After bringing equipment that would normally be used in a clean, isolated lab environment to a rooftop that is exposed to the elements and has no vibration isolation, it was very rewarding to see results showing that we could transmit secure data,” said Alicia Sit, an undergraduate student in Karimi’s lab.
As a next step, the researchers are planning to implement their scheme into a network that includes three links that are about 5.6 kilometers apart and that uses a technology known as adaptive optics to compensate for the turbulence. Eventually, they want to link this network to one that exists now in the city. “Our long-term goal is to implement a quantum communication network with multiple links but using more than four dimensions while trying to get around the turbulence,” said Sit.
