A selection of science songs for summer

Canada’s Perimeter Institute for Theoretical Physics (PI) has compiled a list of science songs and it includes a few Canadian surprises. Here’s more from the July 21, 2016 PI notice received via email.

Ah, summer.

School’s out, the outdoors beckon, and with every passing second a 4.5-billion-year-old nuclear fireball fuses 620 million tons of hydrogen so brightly you’ve gotta wear shades.

Who says you have to stop learning science over the summer?

All you need is the right soundtrack to your next road trip, backyard barbeque, or day at the beach.

Did we miss your favourite science song? Tweet us @Perimeter with the hashtag #SciencePlaylist.

You can find the list and accompanying videos on The Ultimate Science Playlist webpage on the PI website. Here are a few samples,

“History of Everything” – Barenaked Ladies (The Big Bang Theory theme)

You probably know this one as the theme song of The Big Bang Theory. But here’s something you might not know. The tune began as an improvised ditty Barenaked Ladies’ singer Ed Robertson performed one night in Los Angeles after reading Simon Singh’s book Big Bang: The Most Important Scientific Discovery of All Time and Why You Need to Know About It. Lo and behold, in the audience that night were Chuck Lorre and Bill Prady, creators of The Big Bang Theory. The rest is history (of everything).

“Bohemian Gravity” – A Capella Science (Tim Blais)

Tim Blais, the one-man choir behind A Capella Science, is a master at conveying complex science in fun musical parodies. “Bohemian Gravity” is his most famous, but be sure to also check out our collaboration with him about gravitational waves, “LIGO: Feel That Space.”

“NaCl” – Kate and Anna McGarrigle

“NaCl” is a romantic tale of the courtship of a chlorine atom and a sodium atom, who marry and become sodium chloride. “Think of the love you eat,” sings Kate McGarrigle, “when you salt your meat.”

This is just a sampling. At this point, there are 15 science songs on the webpage. Surprisingly, rap is not represented. One other note, you’ll notice all of my samples are Canadian. (Sadly, I had other videos as well but every time I saved a draft I lost at least half or more. It seems the maximum allowed to me is three.).

Here are the others I wanted to include:

“Mandelbrot Set” – Jonathan Coulton

Singer-songwriter Jonathan Coulton (JoCo, to fans) is arguably the patron saint of geek-pop, having penned the uber-catchy credits songs of the Portal games, as well as this loving tribute to a particular set of complex numbers that has a highly convoluted fractal boundary when plotted.

“Higgs Boson Sonification” – Traq 

CERN physicist Piotr Traczyk (a.k.a. Traq) “sonified” data from the experiment that uncovered the Higgs boson, turning the discovery into a high-energy metal riff.

“Why Does the Sun Shine?” – They Might Be Giants

Choosing just one song for this playlist by They Might Be Giants is a tricky task, since They Definitely Are Nerdy. But this one celebrates physics, chemistry, and astronomy while also being absurdly catchy, so it made the list. Honourable mention goes to their entire album for kids, Here Comes Science.

In any event, the PI list is a great introduction to science songs and The Ultimate Science Playlist includes embedded videos for all 15 of the songs selected so far. Happy Summer!

DNA as a sensor

McMaster University (Ontario, Canada) researchers have developed a technique for using DNA (deoxyribonucleic acid) as a sensor according to a July 7, 2016 news item on ScienceDaily,

Researchers at McMaster University have established a way to harness DNA as the engine of a microscopic “machine” they can turn on to detect trace amounts of substances that range from viruses and bacteria to cocaine and metals.

“It’s a completely new platform that can be adapted to many kinds of uses,” says John Brennan, director of McMaster’s Biointerfaces Insitute and co-author of a paper in the journal Nature Communications that describes the technology. “These DNA nano-architectures are adaptable, so that any target should be detectable.”

A July 7, 2016 McMaster University news release (also on EurekAlert), which originated the news item, expands on the theme,

DNA is best known as a genetic material, but is also a very programmable molecule that lends itself to engineering for synthetic applications.

The new method shapes separately programmed pieces of DNA material into pairs of interlocking circles.

The first remains inactive until it is released by the second, like a bicycle wheel in a lock. When the second circle, acting as the lock, is exposed to even a trace of the target substance, it opens, freeing the first circle of DNA, which replicates quickly and creates a signal, such as a colour change.

“The key is that it’s selectively triggered by whatever we want to detect,” says Brennan, who holds the Canada Research Chair in Bioanalytical Chemistry and Biointerfaces. “We have essentially taken a piece of DNA and forced it to do something it was never designed to do. We can design the lock to be specific to a certain key. All the parts are made of DNA, and ultimately that key is defined by how we build it.”

The idea for the “DNA nanomachine” comes from nature itself, explains co-author Yingfu Li, who holds the Canada Research Chair in Nucleic Acids Research.

“Biology uses all kinds of nanoscale molecular machines to achieve important functions in cells,” Li says. “For the first time, we have designed a DNA-based nano-machine that is capable of achieving ultra-sensitive detection of a bacterial pathogen.”

The DNA-based nanomachine is being further developed into a user-friendly detection kit that will enable rapid testing of a variety of substances, and could move to clinical testing within a year.

D-PLACE: an open access database of places, language, culture, and enviroment

In an attempt to be a bit more broad in my interpretation of the ‘society’ part of my commentary I’m including this July 8, 2016 news item on ScienceDaily (Note: A link has been removed),

An international team of researchers has developed a website at d-place.org to help answer long-standing questions about the forces that shaped human cultural diversity.

D-PLACE — the Database of Places, Language, Culture and Environment — is an expandable, open access database that brings together a dispersed body of information on the language, geography, culture and environment of more than 1,400 human societies. It comprises information mainly on pre-industrial societies that were described by ethnographers in the 19th and early 20th centuries.

A July 8, 2016 University of Toronto news release (also on EurekAlert), which originated the news item, expands on the theme,

“Human cultural diversity is expressed in numerous ways: from the foods we eat and the houses we build, to our religious practices and political organisation, to who we marry and the types of games we teach our children,” said Kathryn Kirby, a postdoctoral fellow in the Departments of Ecology & Evolutionary Biology and Geography at the University of Toronto and lead author of the study. “Cultural practices vary across space and time, but the factors and processes that drive cultural change and shape patterns of diversity remain largely unknown.

“D-PLACE will enable a whole new generation of scholars to answer these long-standing questions about the forces that have shaped human cultural diversity.”

Co-author Fiona Jordan, senior lecturer in anthropology at the University of Bristol and one of the project leads said, “Comparative research is critical for understanding the processes behind cultural diversity. Over a century of anthropological research around the globe has given us a rich resource for understanding the diversity of humanity – but bringing different resources and datasets together has been a huge challenge in the past.

“We’ve drawn on the emerging big data sets from ecology, and combined these with cultural and linguistic data so researchers can visualise diversity at a glance, and download data to analyse in their own projects.”

D-PLACE allows users to search by cultural practice (e.g., monogamy vs. polygamy), environmental variable (e.g. elevation, mean annual temperature), language family (e.g. Indo-European, Austronesian), or region (e.g. Siberia). The search results can be displayed on a map, a language tree or in a table, and can also be downloaded for further analysis.

It aims to enable researchers to investigate the extent to which patterns in cultural diversity are shaped by different forces, including shared history, demographics, migration/diffusion, cultural innovations, and environmental and ecological conditions.

D-PLACE was developed by an international team of scientists interested in cross-cultural research. It includes researchers from Max Planck Institute for the Science of Human history in Jena Germany, University of Auckland, Colorado State University, University of Toronto, University of Bristol, Yale, Human Relations Area Files, Washington University in Saint Louis, University of Michigan, American Museum of Natural History, and City University of New York.

The diverse team included: linguists; anthropologists; biogeographers; data scientists; ethnobiologists; and evolutionary ecologists, who employ a variety of research methods including field-based primary data collection; compilation of cross-cultural data sources; and analyses of existing cross-cultural datasets.

“The team’s diversity is reflected in D-PLACE, which is designed to appeal to a broad user base,” said Kirby. “Envisioned users range from members of the public world-wide interested in comparing their cultural practices with those of other groups, to cross-cultural researchers interested in pushing the boundaries of existing research into the drivers of cultural change.”

While it might not seem like that there would be a close link between anthropology and physics in the 19th and early 20th centuries, that information can be mined for more contemporary applications. For example, someone who wants to make a case for a more diverse scientific community may want to develop a social science approach to the discussion. The situation in my June 16, 2016 post titled: Science literacy, science advice, the US Supreme Court, and Britain’s House of Commons, could  be extended into a discussion and educational process using data from D-Place and other sources to make the point,

Science literacy may not be just for the public, it would seem that US Supreme Court judges may not have a basic understanding of how science works. David Bruggeman’s March 24, 2016 posting (on his Pasco Phronesis blog) describes a then current case before the Supreme Court (Justice Antonin Scalia has since died), Note: Links have been removed,

It’s a case concerning aspects of the University of Texas admissions process for undergraduates and the case is seen as a possible means of restricting race-based considerations for admission.  While I think the arguments in the case will likely revolve around factors far removed from science and or technology, there were comments raised by two Justices that struck a nerve with many scientists and engineers.

Both Justice Antonin Scalia and Chief Justice John Roberts raised questions about the validity of having diversity where science and scientists are concerned [emphasis mine].  Justice Scalia seemed to imply that diversity wasn’t esential for the University of Texas as most African-American scientists didn’t come from schools at the level of the University of Texas (considered the best university in Texas).  Chief Justice Roberts was a bit more plain about not understanding the benefits of diversity.  He stated, “What unique perspective does a black student bring to a class in physics?”

To that end, Dr. S. James Gates, theoretical physicist at the University of Maryland, and member of the President’s Council of Advisers on Science and Technology (and commercial actor) has an editorial in the March 25 [2016] issue of Science explaining that the value of having diversity in science does not accrue *just* to those who are underrepresented.

Dr. Gates relates his personal experience as a researcher and teacher of how people’s background inform their practice of science, and that two different people may use the same scientific method, but think about the problem differently.

I’m guessing that both Scalia and Roberts and possibly others believe that science is the discovery and accumulation of facts. In this worldview science facts such as gravity are waiting for discovery and formulation into a ‘law’. They do not recognize that most science is a collection of beliefs and may be influenced by personal beliefs. For example, we believe we’ve proved the existence of the Higgs boson but no one associated with the research has ever stated unequivocally that it exists.

More generally, with D-PLACE and the recently announced Trans-Atlantic Platform (see my July 15, 2016 post about it), it seems Canada’s humanities and social sciences communities are taking strides toward greater international collaboration and a more profound investment in digital scholarship.

Trans-Atlantic Platform (T-AP) is a unique collaboration of humanities and social science researchers from Europe and the Americas

Launched in 2013, the Trans-Atlantic Platform is co-chaired by Dr.Ted Hewitt, president of the Social Sciences and Humanities Research Council of Canada (SSHRC) , and Dr. Renée van Kessel-Hagesteijn, Netherlands Organisation for Scientific Research—Social Sciences (NWO—Social Sciences).

An EU (European Union) publication, International Innovation features an interview about T-AP with Ted Hewitt in a June 30, 2016 posting,

The Trans-Atlantic Platform is a unique collaboration of humanities and social science funders from Europe and the Americas. International Innovation’s Rebecca Torr speaks with Ted Hewitt, President of the Social Sciences and Humanities Research Council and Co-Chair of T-AP to understand more about the Platform and its pilot funding programme, Digging into Data.

Many commentators have called for better integration between natural and social scientists, to ensure that the societal benefits of STEM research are fully realised. Does the integration of diverse scientific disciplines form part of T-AP’s remit, and if so, how are you working to achieve this?

T-AP was designed primarily to promote and facilitate research across SSH. However, given the Platform’s thematic priorities and the funding opportunities being contemplated, we anticipate that a good number of non-SSH [emphasis mine] researchers will be involved.

As an example, on March 1, T-AP launched its first pilot funding opportunity: the T-AP Digging into Data Challenge. One of the sponsors is the Natural Sciences and Engineering Research Council of Canada (NSERC), Canada’s federal funding agency for research in the natural sciences and engineering. Their involvement ensures that the perspective of the natural sciences is included in the challenge. The Digging into Data Challenge is open to any project that addresses research questions in the SSH by using large-scale digital data analysis techniques, and is then able to show how these techniques can lead to new insights. And the challenge specifically aims to advance multidisciplinary collaborative projects.

When you tackle a research question or undertake research to address a social challenge, you need collaboration between various SSH disciplines or between SSH and STEM disciplines. So, while proposals must address SSH research questions, the individual teams often involve STEM researchers, such as computer scientists.

In previous rounds of the Digging into Data Challenge, this has led to invaluable research. One project looked at how the media shaped public opinion around the 1918 Spanish flu pandemic. Another used CT scans to examine hundreds of mummies, ultimately discovering that atherosclerosis, a form of heart disease, was prevalent 4,000 years ago. In both cases, these multidisciplinary historical research projects have helped inform our thinking of the present.

Of course, Digging into Data isn’t the only research area in which T-AP will be involved. Since its inception, T-AP partners have identified three priority areas beyond digital scholarship: diversity, inequality and difference; resilient and innovative societies; and transformative research on the environment. Each of these areas touches on a variety of SSH fields, while the transformative research on the environment area has strong connections with STEM fields. In September 2015, T-AP organised a workshop around this third priority area; environmental science researchers were among the workshop participants.

I wish Hewitt hadn’t described researchers from disciplines other than the humanities and social sciences as “non-SSH.” The designation divides the world in two: us and non-take your pick: non-Catholic/Muslim/American/STEM/SSH/etc.

Getting back to the interview, it is surprisingly Canuck-centric in places,

How does T-AP fit in with Social Sciences and Humanities Research Council of Canada (SSHRC)’s priorities?

One of the objectives in SSHRC’s new strategic plan is to develop partnerships that enable us to expand the reach of our funding. As T-AP provides SSHRC with links to 16 agencies across Europe and the Americas, it is an efficient mechanism for us to broaden the scope of our support and promotion of post-secondary-based research and training in SSH.

It also provides an opportunity to explore cutting edge areas of research, such as big data (as we did with the first call we put out, Digging into Data). The research enterprise is becoming increasingly international, by which I mean that researchers are working on issues with international dimensions or collaborating in international teams. In this globalised environment, SSHRC must partner with international funders to support research excellence. By developing international funding opportunities, T-AP helps researchers create teams better positioned to tackle the most exciting and promising research topics.

Finally, it is a highly effective way of broadly promoting the value of SSH research throughout Canada and around the globe. There are significant costs and complexities involved in international research, and uncoordinated funding from multiple national funders can actually create barriers to collaboration. A platform like T-AP helps funders coordinate and streamline processes.

The interview gets a little more international scope when it turns to the data project,

What is the significance of your pilot funding programme in digital scholarship and what types of projects will it support?

The T-AP Digging into Data Challenge is significant for several reasons. First, the geographic reach of Digging is truly significant. With 16 participants from 11 countries, this round of Digging has significantly broader participation from previous rounds. This is also the first time Digging into Data includes funders from South America.

The T-AP Digging into Data Challenge is open to any research project that addresses questions in SSH. In terms of what those projects will end up being is anybody’s guess – projects from past competitions have involved fields ranging from musicology to anthropology to political science.

The Challenge’s main focus is, of course, the use of big data in research.

You may want to read the interview in its entirety here.

I have checked out the Trans-Atlantic Platform website but cannot determine how someone or some institution might consult that site for information on how to get involved in their projects or get funding. However, there is a T-AP Digging into Data website where there is evidence of the first international call for funding submissions. Sadly, the deadline for the 2016 call has passed if the website is to be believed (sometimes people are late when changing deadline dates).

Deep learning and some history from the Swiss National Science Foundation (SNSF)

A June 27, 2016 news item on phys.org provides a measured analysis of deep learning and its current state of development (from a Swiss perspective),

In March 2016, the world Go champion Lee Sedol lost 1-4 against the artificial intelligence AlphaGo. For many, this was yet another defeat for humanity at the hands of the machines. Indeed, the success of the AlphaGo software was forged in an area of artificial intelligence that has seen huge progress over the last decade. Deep learning, as it’s called, uses artificial neural networks to process algorithmic calculations. This software architecture therefore mimics biological neural networks.

Much of the progress in deep learning is thanks to the work of Jürgen Schmidhuber, director of the IDSIA (Istituto Dalle Molle di Studi sull’Intelligenza Artificiale) which is located in the suburbs of Lugano. The IDSIA doctoral student Shane Legg and a group of former colleagues went on to found DeepMind, the startup acquired by Google in early 2014 for USD 500 million. The DeepMind algorithms eventually wound up in AlphaGo.

“Schmidhuber is one of the best at deep learning,” says Boi Faltings of the EPFL Artificial Intelligence Lab. “He never let go of the need to keep working at it.” According to Stéphane Marchand-Maillet of the University of Geneva computing department, “he’s been in the race since the very beginning.”

A June 27, 2016 SNSF news release (first published as a story in Horizons no. 109 June 2016) by Fabien Goubet, which originated the news item, goes on to provide a brief history,

The real strength of deep learning is structural recognition, and winning at Go is just an illustration of this, albeit a rather resounding one. Elsewhere, and for some years now, we have seen it applied to an entire spectrum of areas, such as visual and vocal recognition, online translation tools and smartphone personal assistants. One underlying principle of machine learning is that algorithms must first be trained using copious examples. Naturally, this has been helped by the deluge of user-generated content spawned by smartphones and web 2.0, stretching from Facebook photo comments to official translations published on the Internet. By feeding a machine thousands of accurately tagged images of cats, for example, it learns first to recognise those cats and later any image of a cat, including those it hasn’t been fed.

Deep learning isn’t new; it just needed modern computers to come of age. As far back as the early 1950s, biologists tried to lay out formal principles to explain the working of the brain’s cells. In 1956, the psychologist Frank Rosenblatt of the New York State Aeronautical Laboratory published a numerical model based on these concepts, thereby creating the very first artificial neural network. Once integrated into a calculator, it learned to recognise rudimentary images.

“This network only contained eight neurones organised in a single layer. It could only recognise simple characters”, says Claude Touzet of the Adaptive and Integrative Neuroscience Laboratory of Aix-Marseille University. “It wasn’t until 1985 that we saw the second generation of artificial neural networks featuring multiple layers and much greater performance”. This breakthrough was made simultaneously by three researchers: Yann LeCun in Paris, Geoffrey Hinton in Toronto and Terrence Sejnowski in Baltimore.

Byte-size learning

In multilayer networks, each layer learns to recognise the precise visual characteristics of a shape. The deeper the layer, the more abstract the characteristics. With cat photos, the first layer analyses pixel colour, and the following layer recognises the general form of the cat. This structural design can support calculations being made upon thousands of layers, and it was this aspect of the architecture that gave rise to the name ‘deep learning’.

Marchand-Maillet explains: “Each artificial neurone is assigned an input value, which it computes using a mathematical function, only firing if the output exceeds a pre-defined threshold”. In this way, it reproduces the behaviour of real neurones, which only fire and transmit information when the input signal (the potential difference across the entire neural circuit) reaches a certain level. In the artificial model, the results of a single layer are weighted, added up and then sent as the input signal to the following layer, which processes that input using different functions, and so on and so forth.

For example, if a system is trained with great quantities of photos of apples and watermelons, it will progressively learn to distinguish them on the basis of diameter, says Marchand-Maillet. If it cannot decide (e.g., when processing a picture of a tiny watermelon), the subsequent layers take over by analysing the colours or textures of the fruit in the photo, and so on. In this way, every step in the process further refines the assessment.

Video games to the rescue

For decades, the frontier of computing held back more complex applications, even at the cutting edge. Industry walked away, and deep learning only survived thanks to the video games sector, which eventually began producing graphics chips, or GPUs, with an unprecedented power at accessible prices: up to 6 teraflops (i.e., 6 trillion calculations per second) for a few hundred dollars. “There’s no doubt that it was this calculating power that laid the ground for the quantum leap in deep learning”, says Touzet. GPUs are also very good at parallel calculations, a useful function for executing the innumerable simultaneous operations required by neural networks.
Although image analysis is getting great results, things are more complicated for sequential data objects such as natural spoken language and video footage. This has formed part of Schmidhuber’s work since 1989, and his response has been to develop recurrent neural networks in which neurones communicate with each other in loops, feeding processed data back into the initial layers.

Such sequential data analysis is highly dependent on context and precursory data. In Lugano, networks have been instructed to memorise the order of a chain of events. Long Short Term Memory (LSTM) networks can distinguish ‘boat’ from ‘float’ by recalling the sound that preceded ‘oat’ (i.e., either ‘b’ or ‘fl’). “Recurrent neural networks are more powerful than other approaches such as the Hidden Markov models”, says Schmidhuber, who also notes that Google Voice integrated LSTMs in 2015. “With looped networks, the number of layers is potentially infinite”, says Faltings [?].

For Schmidhuber, deep learning is just one aspect of artificial intelligence; the real thing will lead to “the most important change in the history of our civilisation”. But Marchand-Maillet sees deep learning as “a bit of hype, leading us to believe that artificial intelligence can learn anything provided there’s data. But it’s still an open question as to whether deep learning can really be applied to every last domain”.

It’s nice to get an historical perspective and eye-opening to realize that scientists have been working on these concepts since the 1950s.

Dear Science Minister Kirsty Duncan and Science, Innovation and Economic Development Minister Navdeep Bains: a Happy Canada Day! open letter

Dear Minister of Science Kirsty Duncan and Minister of Science, Innovation and Economic Development Navdeep Bains,

Thank you both. It’s been heartening to note some of the moves you’ve made since entering office. Taking the muzzles off Environment Canada and Natural Resources Canada scientists was a big relief and it was wonderful to hear that the mandatory longform census was reinstated along with the Experimental Lakes Area programme. (Btw, I can’t be the only one who’s looking forward to hearing the news once Canada’s Chief Science Officer is appointed. In the fall, eh?)

Changing the National Science and Technology week by giving it a news name “Science Odyssey” and rescheduling it from the fall to the spring seems to have revitalized the effort. Then, there was the news about a review focused on fundamental science (see my June 16, 2016 post). It seems as if the floodgates have opened or at least communication about what’s going on has become much freer. Brava and Bravo!

The recently announced (June 29, 2016) third assessment on the State of S&T (Science and Technology) and IR&D (Industrial Research and Development; my July 1, 2016 post features the announcement) by the Council of Canadian Academies adds to the impression that you both have adopted a dizzying pace for science of all kinds in Canada.

With the initiatives I’ve just mentioned in mind, it would seem that encouraging a more vital science culture and and re-establishing science as a fundamental part of Canadian society is your aim.

Science education and outreach as a whole population effort

It’s facey to ask for more but that’s what I’m going to do.

In general, the science education and outreach efforts in Canada have focused on children. This is wonderful but not likely to be as successful as we would hope when a significant and influential chunk of the population is largely ignored: adults. (There is a specific situation where outreach to adults is undertaken but more about that later.)

There is research suggesting that children’s attitudes to science and future careers is strongly influenced by their family. From my Oct. 9, 2013 posting,

One of the research efforts in the UK is the ASPIRES research project at King’s College London (KCL), which is examining children’s attitudes to science and future careers. Their latest report, Ten Science Facts and Fictions: the case for early education about STEM careers (PDF), is profiled in a Jan. 11, 2012 news item on physorg.com (from the news item),

Professor Archer [Louise Archer, Professor of Sociology of Education at King’s] said: “Children and their parents hold quite complex views of science and scientists and at age 10 or 11 these views are largely positive. The vast majority of children at this age enjoy science at school, have parents who are supportive of them studying science and even undertake science-related activities in their spare time. They associate scientists with important work, such as finding medical cures, and with work that is well paid.

“Nevertheless, less than 17 per cent aspire to a career in science. These positive impressions seem to lead to the perception that science offers only a very limited range of careers, for example doctor, scientist or science teacher. It appears that this positive stereotype is also problematic in that it can lead people to view science as out of reach for many, only for exceptional or clever people, and ‘not for me’. [emphases mine]

Family as a bigger concept

I suggest that ‘family’ be expanded to include the social environment in which children operate. When I was a kid no one in our family or extended group of friends had been to university let alone become a scientist. My parents had aspirations for me but when it came down to brass tacks, even though I was encouraged to go to university, they were much happier when I dropped out and got a job.

It’s very hard to break out of the mold. The odd thing about it all? I had two uncles who were electricians which when you think about it means they were working in STEM (science, technology,engineering, mathematics) jobs. Electricians, then and now. despite their technical skills, are considered tradespeople.

It seems to me that if more people saw themselves as having STEM or STEM-influenced occupations: hairdressers, artists, automechanics, plumbers, electricians, musicians, etc., we might find more children willing to engage directly in STEM opportunities. We might also find there’s more public support for science in all its guises.

That situation where adults are targeted for science outreach? It’s when the science is considered controversial or problematic and, suddenly, public (actually they mean voter) engagement or outreach is considered vital.

Suggestion

Given the initiatives you both have undertaken and Prime Minister Trudeau’s recent public outbreak of enthusiasm for and interest in quantum computing (my April 18, 2016 posting), I’m hopeful that you will consider the notion and encourage (fund?) science promotion programmes aimed at adults. Preferably attention-grabbing and imaginative programmes.

Should you want to discuss the matter further (I have some suggestions), please feel free to contact me.

Regardless, I’m very happy to see the initiatives that have been undertaken and, just as importantly, the communication about science.

Yours sincerely,

Maryse de la Giroday
(FrogHeart blog)

P.S. I very much enjoyed the June 22, 2016 interview with Léo Charbonneau for University Affairs,

UA: Looking ahead, where would you like Canada to be in terms of research in five to 10 years?

Dr. Duncan: Well, I’ll tell you, it breaks my heart that in a 10-year period we fell from third to eighth place among OECD countries in terms of HERD [government expenditures on higher education research and development as a percentage of gross domestic product]. That should never have happened. That’s why it was so important for me to get that big investment in the granting councils.

Do we have a strong vision for science? Do we have the support of the research community? Do we have the funding systems that allow our world-class researchers to do the work they want do to? And, with the chief science officer, are we building a system where we have the evidence to inform decision-making? My job is to support research and to make sure evidence makes its way to the cabinet table.

As stated earlier, I’m hoping you will expand your vision to include Canadian society, not forgetting seniors (being retired or older doesn’t mean that you’re senile and/or incapable of public participation), and supporting Canada’s emerging science media environment.

P.P.S. As a longstanding observer of the interplay between pop culture, science, and society I was much amused and inspired by news of Justin Trudeau’s emergence as a character in a Marvel comic book (from a June 28, 2016 CBC [Canadian Broadcasting Corporation] news online item),

Make way, Liberal cabinet: Prime Minister Justin Trudeau will have another all-Canadian crew in his corner as he suits up for his latest feature role — comic book character.

Trudeau will grace the variant cover of issue No. 5 of Marvel’s “Civil War II: Choosing Sides,” due out Aug. 31 [2016].

Trudeau is depicted smiling, sitting relaxed in the boxing ring sporting a Maple Leaf-emblazoned tank, black shorts and red boxing gloves. Standing behind him are Puck, Sasquatch and Aurora, who are members of Canadian superhero squad Alpha Flight. In the left corner, Iron Man is seen with his arms crossed.

“I didn’t want to do a stuffy cover — just like a suit and tie — put his likeness on the cover and call it a day,” said award-winning Toronto-based cartoonist Ramon Perez.

“I wanted to kind of evoke a little bit of what’s different about him than other people in power right now. You don’t see (U.S. President Barack) Obama strutting around in boxing gear, doing push-ups in commercials or whatnot. Just throwing him in his gear and making him almost like an everyday person was kind of fun.”

The variant cover featuring Trudeau will be an alternative to the main cover in circulation showcasing Aurora, Puck, Sasquatch and Nick Fury.

It’s not the first time a Canadian Prime Minister has been featured in a Marvel comic book (from the CBC news item),

Third assessment of The State of Science and Technology and Industrial Research and Development in Canada announced

The last State of Science and Technology and Industrial Research and Development in Canada assessments were delivered in 2012 and 2013 respectively, which seems a shortish gap between assessments, as these things go. Having On a positive note, this may mean that the government has seen the importance of a more agile approach as the pace of new discoveries is ever quickening. Here’s more from a June 29, 2016 announcement from the Canadian Council of Academies (CCA; received via email),

CCA to undertake third assessment on the State of S&T and IR&D

June 29, 2016 (Ottawa, ON) – The Council of Canadian Academies (CCA) is pleased to announce the launch of a new assessment on the state of science and technology (S&T) and industrial research and development (IR&D) in Canada. This assessment, referred by Innovation, Science and Economic Development Canada (ISED), will be the third installment in the state of S&T and IR&D series by the CCA.

“I’m delighted the government continues to recognize the value of the CCA’s state of S&T and IR&D reports,” said Eric M. Meslin, President and CEO of the Council of Canadian Academies. “An updated assessment will enable policy makers, and others, such as industry leaders, universities, and the private sector, to draw on current Canadian S&T and IR&D data to make evidence-informed decisions.”

The CCA’s reports on the state of S&T and state of IR&D provide valuable data and analysis documenting Canada’s S&T and IR&D strengths and weaknesses. New data will help identify trends that have emerged in the Canadian S&T and IR&D environment in the past four to five years.

Under the guidance of the CCA’s Scientific Advisory Committee, a multidisciplinary, multi-sectoral expert panel is being assembled. It is anticipated that the final report will be released in a two-part sequence, with an interim report released in late 2016 and a final report released in 2017.

To learn more about this and the CCA’s other active assessments, visit Assessments in Progress.

The announcement offers information about the series of assessments,

About the State of S&T and IR&D Assessment Series

Current charge: What is the current state of science and technology and industrial research and development in Canada?

Sponsor: Innovation, Science and Economic Development Canada (ISED)

This assessment will be the third edition in the State of S&T and Industrial R&D assessment series.

Background on the Series

  • In 2006, the CCA completed its first report on The State of Science and Technology in Canada. The findings were integral to the identification of S&T priority areas in the federal government’s 2007 S&T strategy,  Mobilizing Science and Technology to Canada’s Advantage [the original link was not functional; I found the report on an archived page].
  • In 2010 the CCA was again asked to assess the state of S&T in Canada.  The State of Science and Technology in Canada, 2012 updated the 2006 report and provided a thorough analysis of the scientific disciplines and technological applications where Canada excelled in a global context. It also identified Canada’s S&T strengths, regional specializations, and emerging research areas.
  • In 2013, the CCA published The State of Industrial R&D in Canada. This report provided an in-depth analysis of research and development activities in Canadian industries and is one of the most detailed and systematic studies of the state of IR&D ever undertaken in Canada.

I wrote three posts after the second assessment was delivered in 2012. My Sept. 27, 2012 posting was an announcement of its launch and then I offered a two-part critique: part 1 was in a Dec. 28, 2012 posting and part 2 was in a second Dec. 28, 2012 posting. I did not write about the 2013 report on Canada’s industrial research and development efforts.

Given the size of the 2012 assessment of science and technology at 232 pp. (PDF) and the 2013 assessment of industrial research and development at 220 pp. (PDF) with two expert panels, the imagination boggles at the potential size of the 2016 expert panel and of the 2016 assessment combining the two areas.

Given the timing for the interim report (late 2016), I wonder if they are planning to release at the 2016 Canadian Science Policy Conference, which is being held in Ottawa from Nov. 8 – 10, 2016 (for the second year in a row and, I believe, the third time in eight conferences).

Combat cells (Robot Wars for cells) and a plea from Concordia University

Students at Concordia University (located in Montréal, Québec, Canada) are requesting help (financial or laboratory supplies) for their submission to  the 2016 iGEM (International Genetically Engineered Machine) competition.

Here’s a little about their entry (from a June 16, 2016 request received via email),

For this year’s project, we plan to design a biological system that mimics the concept of the popular TV series Robot Wars. We will be engineering cellular species to wear nanoparticles as battle shields and then use microfluidics to guide them through an obstacle course leading to a battledome, where both cells will engage into a duel. Essentially, we want to test the interactions between nanoparticles and cell membranes, as well as their protective abilities against varying environmental conditions and other equipped cells. The method in which we will adapt Robot Wars for synthetic biology is by creating a web series that will visualize the cell battle and communicate the research behind it. This web series will serve as an entertaining  medium to educate and inspire the audience to develop an interest in science. We are incorporating the emerging fields of  synthetic biology, nanotechnology and microfluidics to make this process possible.  Furthermore, this study will contribute to the advancement of nanotechnology, an interdisciplinary field aiming to make applicable improvements in other fields such as medicine, optics and cosmetics.

Here’s a little more about iGEM (from the organization’s homepage),

The iGEM Foundation is dedicated to education and competition, advancement of synthetic biology, and the development of open community and collaboration.

The main program at the iGEM Foundation is the International Genetically Engineered Machine (iGEM) Competition. The iGEM Competition is the premiere student competition in Synthetic Biology. Since 2004, participants of the competition have experienced education, teamwork, sharing, and more in a unique competition setting.

The deadline for donations/sponsorships is the end of September 2016 and sponsors/donors will be acknowledged on “our website, all of our social media accounts (Facebook, Instagram, Twitter), at our community outreach events and at the competition [from the June 16, 2016 email].”

Finally, there’s this:

We are excited to make this year’s project a reality and we are determined to win gold. Any help, either financially or by the donation of laboratory supplies, would contribute to the development of our project and would be greatly appreciated.

Good luck to the students! Hopefully one or more of my readers will be able to help. In which case, thank you!

A treasure trove of molecule and battery data released to the public

Scientists working on The Materials Project have taken the notion of open science to their hearts and opened up access to their data according to a June 9, 2016 news item on Nanowerk,

The Materials Project, a Google-like database of material properties aimed at accelerating innovation, has released an enormous trove of data to the public, giving scientists working on fuel cells, photovoltaics, thermoelectrics, and a host of other advanced materials a powerful tool to explore new research avenues. But it has become a particularly important resource for researchers working on batteries. Co-founded and directed by Lawrence Berkeley National Laboratory (Berkeley Lab) scientist Kristin Persson, the Materials Project uses supercomputers to calculate the properties of materials based on first-principles quantum-mechanical frameworks. It was launched in 2011 by the U.S. Department of Energy’s (DOE) Office of Science.

A June 8, 2016 Berkeley Lab news release, which originated the news item, provides more explanation about The Materials Project,

The idea behind the Materials Project is that it can save researchers time by predicting material properties without needing to synthesize the materials first in the lab. It can also suggest new candidate materials that experimentalists had not previously dreamed up. With a user-friendly web interface, users can look up the calculated properties, such as voltage, capacity, band gap, and density, for tens of thousands of materials.

Two sets of data were released last month: nearly 1,500 compounds investigated for multivalent intercalation electrodes and more than 21,000 organic molecules relevant for liquid electrolytes as well as a host of other research applications. Batteries with multivalent cathodes (which have multiple electrons per mobile ion available for charge transfer) are promising candidates for reducing cost and achieving higher energy density than that available with current lithium-ion technology.

The sheer volume and scope of the data is unprecedented, said Persson, who is also a professor in UC Berkeley’s Department of Materials Science and Engineering. “As far as the multivalent cathodes, there’s nothing similar in the world that exists,” she said. “To give you an idea, experimentalists are usually able to focus on one of these materials at a time. Using calculations, we’ve added data on 1,500 different compositions.”

While other research groups have made their data publicly available, what makes the Materials Project so useful are the online tools to search all that data. The recent release includes two new web apps—the Molecules Explorer and the Redox Flow Battery Dashboard—plus an add-on to the Battery Explorer web app enabling researchers to work with other ions in addition to lithium.

“Not only do we give the data freely, we also give algorithms and software to interpret or search over the data,” Persson said.

The Redox Flow Battery app gives scientific parameters as well as techno-economic ones, so battery designers can quickly rule out a molecule that might work well but be prohibitively expensive. The Molecules Explorer app will be useful to researchers far beyond the battery community.

“For multivalent batteries it’s so hard to get good experimental data,” Persson said. “The calculations provide rich and robust benchmarks to assess whether the experiments are actually measuring a valid intercalation process or a side reaction, which is particularly difficult for multivalent energy technology because there are so many problems with testing these batteries.”

Here’s a screen capture from the Battery Explorer app,

The news release goes on to describe a new discovery made possible by The Materials Project (Note: A link has been removed),

Together with Persson, Berkeley Lab scientist Gerbrand Ceder, postdoctoral associate Miao Liu, and MIT graduate student Ziqin Rong, the Materials Project team investigated some of the more promising materials in detail for high multivalent ion mobility, which is the most difficult property to achieve in these cathodes. This led the team to materials known as thiospinels. One of these thiospinels has double the capacity of the currently known multivalent cathodes and was recently synthesized and tested in the lab by JCESR researcher Linda Nazar of the University of Waterloo, Canada.

“These materials may not work well the first time you make them,” Persson said. “You have to be persistent; for example you may have to make the material very phase pure or smaller than a particular particle size and you have to test them under very controlled conditions. There are people who have actually tried this material before and discarded it because they thought it didn’t work particularly well. The power of the computations and the design metrics we have uncovered with their help is that it gives us the confidence to keep trying.”

The researchers were able to double the energy capacity of what had previously been achieved for this kind of multivalent battery. The study has been published in the journal Energy & Environmental Science in an article titled, “A High Capacity Thiospinel Cathode for Mg Batteries.”

“The new multivalent battery works really well,” Persson said. “It’s a significant advance and an excellent proof-of-concept for computational predictions as a valuable new tool for battery research.”

Here’s a link to and a citation for the paper,

A high capacity thiospinel cathode for Mg batteries by Xiaoqi Sun, Patrick Bonnick, Victor Duffort, Miao Liu, Ziqin Rong, Kristin A. Persson, Gerbrand Ceder and  Linda F. Nazar. Energy Environ. Sci., 2016, Advance Article DOI: 10.1039/C6EE00724D First published online 24 May 2016

This paper seems to be behind a paywall.

Getting back to the news release, there’s more about The Materials Project in relationship to its membership,

The Materials Project has attracted more than 20,000 users since launching five years ago. Every day about 20 new users register and 300 to 400 people log in to do research.

One of those users is Dane Morgan, a professor of engineering at the University of Wisconsin-Madison who develops new materials for a wide range of applications, including highly active catalysts for fuel cells, stable low-work function electron emitter cathodes for high-powered microwave devices, and efficient, inexpensive, and environmentally safe solar materials.

“The Materials Project has enabled some of the most exciting research in my group,” said Morgan, who also serves on the Materials Project’s advisory board. “By providing easy access to a huge database, as well as tools to process that data for thermodynamic predictions, the Materials Project has enabled my group to rapidly take on materials design projects that would have been prohibitive just a few years ago.”

More materials are being calculated and added to the database every day. In two years, Persson expects another trove of data to be released to the public.

“This is the way to reach a significant part of the research community, to reach students while they’re still learning material science,” she said. “It’s a teaching tool. It’s a science tool. It’s unprecedented.”

Supercomputing clusters at the National Energy Research Scientific Computing Center (NERSC), a DOE Office of Science User Facility hosted at Berkeley Lab, provide the infrastructure for the Materials Project.

Funding for the Materials Project is provided by the Office of Science (US Department of Energy], including support through JCESR [Joint Center for Energy Storage Research].

Happy researching!

Canadian science petition and a science diplomacy event in Ottawa on June 21, 2016*

The Canadian science policy and science funding scene is hopping these days. Canada’s Minister of Science, Kirsty Duncan, announced a new review of federal funding for fundamental science on Monday, June 13, 2016 (see my June 15, 2016 post for more details and a brief critique of the panel) and now, there’s a new Parliamentary campaign for a science advisor and a Canadian Science Policy Centre event on science diplomacy.

Petition for a science advisor

Kennedy Stewart, Canadian Member of Parliament (Burnaby South) and NDP (New Democratic Party) Science Critic, has launched a campaign for independent science advice for the government. Here’s more from a June 15, 2016 announcement (received via email),

After years of muzzling and misuse of science by the Conservatives, our scientists need lasting protections in order to finally turn the page on the lost Harper decade.

I am writing to ask your support for a new campaign calling for an independent science advisor.

While I applaud the new Liberal government for their recent promises to support science, we have a long way to go to rebuild Canada’s reputation as a global knowledge leader. As NDP Science Critic, I continue to push for renewed research funding and measures to restore scientific integrity.

Canada badly needs a new science advisor to act as a public champion for research and evidence in Ottawa. Although the Trudeau government has committed to creating a Chief Science Officer, the Minister of Science – Dr. Kirsty Duncan – has yet to state whether or not the new officer will be given real independence and a mandate protected by law.

Today, we’re launching a new parliamentary petition calling for just that: https://petitions.parl.gc.ca/en/Petition/Sign/e-415

Can you add your name right now?

Canada’s last national science advisor lacked independence from the government and was easily eliminated in 2008 after the anti-science Harper Conservatives took power.

That’s why the Minister needs to build the new CSO to last and entrench the position in legislation. Rhetoric and half-measures aren’t good enough.

Please add your voice for public science by signing our petition to the Minister of Science.

Thank you for your support,

Breakfast session on science diplomacy

One June 21, 2016 the Canadian Science Policy Centre is presenting a breakfast session on Parliament Hill in Ottawa, (from an announcement received via email),

“Science Diplomacy in the 21st Century: The Potential for Tomorrow”
Remarks by Dr. Vaughan Turekian,
Science and Technology Adviser to Secretary of State John Kerry

Event Information
Tuesday, June 21, 2016, Room 238-S, Parliament Hill
7:30am – 8:00am – Continental Breakfast
8:00am – 8:10am – Opening Remarks, MP Terry Beech
8:10am – 8:45am – Dr. Vaughan Turekian Remarks and Q&A

Dr. Turekian’s visit comes during a pivotal time as Canada is undergoing fundamental changes in numerous policy directions surrounding international affairs. With Canada’s comeback on the world stage, there is great potential for science to play an integral role in the conduct of our foreign affairs.  The United States is currently one of the leaders in science diplomacy, and as such, listening to Dr.Turekian will provide a unique perspective from the best practices of science diplomacy in the US.

Actually, Dr. Turekian’s visit comes before a North American Summit being held in Ottawa on June 29, 2016 and which has already taken a scientific turn. From a June 16, 2016 news item on phys.org,

Some 200 intellectuals, scientists and artists from around the world urged the leaders of Mexico, the United States and Canada on Wednesday to save North America’s endangered migratory Monarch butterfly.

US novelist Paul Auster, environmental activist Robert F. Kennedy Jr., Canadian poet [Canadian media usually describe her as a writer] Margaret Atwood, British writer Ali Smith and India’s women’s and children’s minister Maneka Sanjay Gandhi were among the signatories of an open letter to the three leaders.

US President Barack Obama, Canadian Prime Minister Justin Trudeau and Mexican President Enrique Pena Nieto will hold a North American summit in Ottawa on June 29 [2016].

The letter by the so-called Group of 100 calls on the three leaders to “take swift and energetic actions to preserve the Monarch’s migratory phenomenon” when they meet this month.

In 1996-1997, the butterflies covered 18.2 hectares (45 acres) of land in Mexico’s central mountains.

It fell to 0.67 hectares in 2013-2014 but rose to 4 hectares this year. Their population is measured by the territory they cover.

They usually arrive in Mexico between late October and early November and head back north in March.

Given this turn of events, I wonder how Turekian, given that he’s held his current position for less than a year, might (or might not) approach the question of Monarch butterflies and diplomacy.

I did a little research about Turekian and found this Sept. 10, 2016 news release announcing his appointment as the Science and Technology Adviser to the US Secretary of State,

On September 8, Dr. Vaughan Turekian, formerly the Chief International Officer at The American Association for the Advancement of Science (AAAS), was named the 5th Science and Technology Adviser to the Secretary of State. In this capacity, Dr. Turekian will advise the Secretary of State and the Under Secretary for Economic Growth, Energy, and the Environment on international environment, science, technology, and health matters affecting the foreign policy of the United States. Dr. Turekian will draw upon his background in atmospheric chemistry and extensive policy experience to promote science, technology, and engineering as integral components of U.S. diplomacy.

Dr. Turekian brings both technical expertise and 14 years of policy experience to the position. As former Chief International Officer for The American Association for the Advancement of Science (AAAS) and Director of AAAS’s Center for Science Diplomacy, Dr. Turekian worked to build bridges between nations based on shared scientific goals, placing special emphasis on regions where traditional political relationships are strained or do not exist. As Editor-in-Chief of Science & Diplomacy, an online quarterly publication, Dr. Turekian published original policy pieces that have served to inform international science policy recommendations. Prior to his work at AAAS, Turekian worked at the State Department as Special Assistant and Adviser to the Under Secretary for Global Affairs on issues related to sustainable development, climate change, environment, energy, science, technology, and health and as a Program Director for the Committee on Global Change Research at the National Academy of Sciences where he was study director for a White House report on climate change science.

Turekian’s last editorial for Science & Diplomacy dated June 30, 2015 features a title (Evolving Institutions for Twenty-First Century [Science] Diplomacy) bearing a resemblance to the title for his talk in Ottawa and perhaps it provides a preview (spoilers),

Over the recent decade, its treatment of science and technology issues has increased substantially, with a number of cover stories focused on topics that bridge science, technology, and foreign affairs. This thought leadership reflects a broader shift in thinking within institutions throughout the world about the importance of better integrating the communities of science and diplomacy in novel ways.

In May, a high-level committee convened by Japan’s minister of foreign affairs released fifteen recommendations for how Japan could better incorporate its scientific and technological expertise into its foreign policy. While many of the recommendations were to be predicted, including the establishment of the position of science adviser to the foreign minister, the breadth of the recommendations highlighted numerous new ways Japan could leverage science to meet its foreign policy objectives. The report itself marks a turning point for an institution looking to upgrade its ability to meet and shape the challenges of this still young century.

On the other side of the Pacific, the U.S. National Academy of Sciences released its own assessment of science in the U.S. Department of State. Their report, “Diplomacy for the 21st Century: Embedding a Culture of Science and Technology Throughout the Department of State,” builds on its landmark 1999 report, which, among other things, established the position of science and technology adviser to the secretary of state. The twenty-seven recommendations in the new report are wide ranging, but as a whole speak to the fact that while one of the oldest U.S. institutions of government has made much progress toward becoming more scientifically and technologically literate, there are many more steps that could be taken to leverage science and technology as a key element of U.S. foreign policy.

These two recent reports highlight the importance of foreign ministries as vital instruments of science diplomacy. These agencies of foreign affairs, like their counterparts around the world, are often viewed as conservative and somewhat inflexible institutions focused on stability rather than transformation. However, they are adjusting to a world in which developments in science and technology move rapidly and affect relationships and interactions at bilateral, regional, and global scales.

At the same time that some traditional national instruments of diplomacy are evolving to better incorporate science, international science institutions are also evolving to meet the diplomatic and foreign policy drivers of this more technical century. …

It’s an interesting read and I’m glad to see the mention of Japan in his article. I’d like to see Canadian science advice and policy initiatives take more notice of the rest of the world rather than focusing almost solely on what’s happening in the US and Great Britain (see my June 15, 2016 post for an example of what I mean). On another note, it was disconcerting to find out that Turekian believes that we are only now moving past the Cold War politics of the past.

Unfortunately for anyone wanting to attend the talk, ticket sales have ended even though they were supposed to be open until June 17, 2016. And, there doesn’t seem to be a wait list.

You may want to try arriving at the door and hoping that people have cancelled or fail to arrive therefore acquiring a ticket. Should you be an MP (Member of Parliament), Senator, or guest of the Canadian Science Policy Conference, you get a free ticket. Should you be anyone else, expect to pay $15, assuming no one is attempting to scalp (sell one for more than it cost) these tickets.
