Art, sound, AI, & the Metacreation Lab’s Spring 2021 newsletter

The Metacreation Lab’s Spring 2021 newsletter (received via email) features a number of events either currently taking place or about to take place.

2021 AI Song Contest

2021 marks the 2nd year for this international event, an artificial intelligence/AI Song Contest 2021. The folks at Simon Fraser University’s (SFU) Metacreation Lab have an entry for the 2021 event, A song about the weekend (and you can do whatever you want). Should you click on the song entry, you will find an audio file, a survey/vote consisting of four questions and, if you keep scrolling down, more information about the creative, team, the song and more,

Driven by collaborations involving scientists, experts in artificial intelligence, cognitive sciences, designers, and artists, the Metacreation Lab for Creative AI is at the forefront of the development of generative systems, whether these are embedded in interactive experiences or automating workflows integrated into cutting-edge creative software.

Team:

Cale Plut (Composer and musician) is a PhD Student in the Metacreation lab, researching AI music applications in video games.

Philippe Pasquier (Producer and supervisor) is an Associate Professor, and leads the Metacreation Lab. 

Jeff Ens (AI programmer) is a PhD Candidate in the Metacreation lab, researching AI models for music generation.

Renaud Tchemeube (Producer and interaction designer) is a PhD Student in the Metacreation Lab, researching interaction software design for creativity.

Tara Jadidi (Research Assistant) is an undergraduate student at FUM, Iran, working with the Metacreation lab.

Dimiter Zlatkov (Research Assistant) is an undergraduate student at UBC, working with the Metacreation lab.

ABOUT THE SONG

A song about the weekend (and you can do whatever you want) explores the relationships between AI, humans, labour, and creation in a lighthearted and fun song. It is co-created with the Multi-track Music Machine (MMM)

Through the history of automation and industrialization, the relationship between the labour magnification power of automation and the recipients of the benefits of that magnification have been in contention. While increasing levels of automation are often accompanied by promises of future leisure increases, this rarely materializes for the workers whose labour is multiplied. By primarily using automated methods to create a “fun” song about leisure, we highlight both the promise of AI-human cooperation as well as the disparities in its real-world deployment. 

As for the competition itself, here’s more from the FAQs (frequently asked questions),

What is the AI Song Contest?

AI Song Contest is an international creative AI contest. Teams from all over the world try to create a 4-minute pop song with the help of artificial intelligence.

When and where does it take place?

Between June 1, 2021 and July 1, 2021 voting is open for the international public. On July 6 there will be multiple online panel sessions, and the winner of the AI Song Contest 2021 will be announced in an online award ceremony. All sessions on July 6 are organised in collaboration with Wallifornia MusicTech.

How is the winner determined?

Each participating team will be awarded two sets of points: one a public vote by the contest’s international audience, the other the determination of an expert jury.

Anyone can evaluate as many songs as they like: from one, up to all thirty-eight. Every song can be evaluated only once. Even though it won’t count in the grand total, lyrics can be evaluated too; we do like to determine which team wrote the best accoring to the audience.

Can I vote multiple times for the same team?

No, votes are controlled by IP address. So only one of your votes will count.

Is this the first time the contest is organised?

This is the second time the AI Song Contest is organised. The contest was first initiated in 2020 by Dutch public broadcaster VPRO together with NPO Innovation and NPO 3FM. Teams from Europe and Australia tried to create a Eurovision kind of song with the help of AI. Team Uncanny Valley from Australia won the first edition with their song Beautiful the World. The 2021 edition is organised independently.

What is the definition of artificial intelligence in this contest?

Artificial intelligence is a very broad concept. For this contest it will mean that teams can use techniques such as -but not limited to- machine learning, such as deep learning, natural language processing, algorithmic composition or combining rule-based approaches with neural networks for the creation of their songs. Teams can create their own AI tools, or use existing models and algorithms.  

What are possible challenges?

Read here about the challenges teams from last year’s contest faced.

As an AI researcher, can I collaborate with musicians?

Yes – this is strongly encouraged!

For the 2020 edition, all songs had to be Eurovision-style. Is that also the intention for 2021 entries?

Last year, the first year the contest was organized, it was indeed all about Eurovision. For this year’s competition, we are trying to expand geographically, culturally, and musically. Teams from all over the world can compete, and songs in all genres can be submitted.

If you’re not familiar with Eurovision-style, you can find a compilation video with brief excerpts from the 26 finalists for Eurovision 2021 here (Bill Young’s May 23, 2021 posting on tellyspotting.kera.org; the video runs under 10 mins.). There’s also the “Eurovision Song Contest: The Story of Fire Saga” 2020 movie starring Rachel McAdams, Will Ferrell, and Dan Stevens. It’s intended as a gentle parody but the style is all there.

ART MACHINES 2: International Symposium on Machine Learning and Art 2021

The symposium, Art Machines 2, started yesterday (June 10, 2021 and runs to June 14, 2021) in Hong Kong and SFU’s Metacreation Lab will be represented (from the Spring 2021 newsletter received via email),

On Sunday, June 13 [2021] at 21:45 Hong Kong Standard Time (UTC +8) as part of the Sound Art Paper Session chaired by Ryo Ikeshiro, the Metacreation Lab’s Mahsoo Salimi and Philippe Pasquier will present their paper, Exploiting Swarm Aesthetics in Sound Art. We’ve included a more detailed preview of the paper in this newsletter below.

Concurrent with ART MACHINES 2 is the launch of two exhibitions – Constructing Contexts and System Dreams. Constructing Contexts, curated by Tobias Klein and Rodrigo Guzman-Serrano, will bring together 27 works with unique approaches to the question of contexts as applied by generative adversarial networks. System Dreams highlights work from the latest MFA talent from the School of Creative Media. While the exhibitions take place in Hong Kong, the participating artists and artwork are well documented online.

Liminal Tones: Swarm Aesthetics in Sound Art

Applications of swarm aesthetics in music composition are not new and have already resulted in volumes of complex soundscapes and musical compositions. Using an experimental approach, Mahsoo Salimi and Philippe Pasquier create a series of sound textures know as Liminal Tones (B/ Rain Dream) based on swarming behaviours

Findings of the Liminal Tones project will be presented in papers for the Art Machines 2: International Symposium on Machine Learning (June 10-14 [2021]) and the International Conference on Swarm Intelligence (July 17-21 [2021]).

Talk about Creative AI at the University of British Columbia

This is the last item I’m excerpting from the newsletter. (Should you be curious about what else is listed, you can go to the Metacreation Lab’s contact page and sign up for the newsletter there.) On June 22, 2021 at 2:00 PM PDT, there will be this event,

Creative AI: on the partial or complete automation of creative tasks @ CAIDA

Philippe Pasquier will be giving a talk on creative applications of AI at CAIDA: UBC ICICS Centre for Artificial Intelligence Decision-making and Action. Overviewing the state of the art of computer-assisted creativity and embedded systems and their various applications, the talk will survey the design, deployment, and evaluation of generative systems.

Free registration for the talk is available at the link below.

TRIUMF (Canada’s national particle accelerator centre) welcomes Nigel Smith as its new Chief Executive Officer (CEO) on May 17, 2021and some Hollywood news

I have two bits of news as noted in the headline. There’s news about TRIUMF located on the University of British Columbia (UBC) endowment lands and news about Dr. Suzanne Simard (UBC Forestry) and her memoir, Finding the Mother Tree: Discovering the Wisdom of the Fores.

Nigel Smith and TRIUMF (Canada’s national particle accelerator centre)

As soon as I saw his first name, Nigel, I bet myself he’d be from the UK (more about that later in this posting). This is TRIUMF’s third CEO since I started science blogging in May 2008. When I first started it was called TRIUMF (Canada’s National Laboratory for Particle and Nuclear Physics) but these days it’s TRIUMF (Canada’s national particle accelerator centre).

As for the organization’s latest CEO, here’s more from a TRIUMF February 12, 2021 announcement page ( the text is identical to TRIUMF’s February 12, 2021 press release),

Dr. Nigel Smith, Executive Director of SNOLAB, has been selected to serve as the next Director of TRIUMF.  

Succeeding Dr. Jonathan Bagger, who departed TRIUMF in January 2021 to become CEO of the American Physical Society, Dr. Smith’s appointment comes as the result of a highly competitive, six-month international search. Dr. Smith will begin his 5-year term as TRIUMF Director on May 17, 2021. 

“I am truly honoured to have been selected as the next Director of TRIUMF”, said Dr. Smith. “I have long been engaged with TRIUMF’s vibrant community and have been really impressed with the excellence of its science, capabilities and people. TRIUMF plays a unique and vital role in Canada’s research ecosystem and I look forward to help continue the legacy of excellence upheld by Dr. Jonathan Bagger and the previous TRIUMF Directors”.  

Describing what interested him in the position, Smith spoke to the breadth and impact of TRIUMF’s diverse science programs, stating “TRIUMF has an amazing portfolio of research covering fundamental and applied science that also delivers tangible societal impact through its range of medical and commercialisation initiatives. I am extremely excited to have the opportunity to lead a laboratory with such a broad and world-leading science program.” 

“Nigel brings all the necessary skills and background to the role of Director,” said Dr. Digvir Jayas, Interim Director of TRIUMF, Chair of the TRIUMF Board of Management, and Vice-President, Research and International at the University of Manitoba. “As Executive Director of SNOLAB, Dr. Smith is both a renowned researcher and experienced laboratory leader who offers a tremendous track record of success spanning the local, national, and international spheres. The Board of Management is thrilled to bring Nigel’s expertise to TRIUMF so he may help guide the laboratory through many of the exciting developments on the horizon.  

Dr. Smith joins TRIUMF at an important period in the laboratory’s history, moving into the second year of our current Five-Year Plan (2020-2025) and preparing to usher in a new era of science and innovation that will include the completion of the Advance Rare Isotope Laboratory (ARIEL) and the Institute for Advanced Medical Isotopes (IAMI) [not to be confused with Amii {Alberta Machine Intelligence Institute}]. This new infrastructure, alongside TRIUMF’s existing facilities and world-class research programs, will solidify Canada’s position as a global leader in both fundamental and applied research. 

Dr. Smith expressed his optimism for TRIUMF, saying “I am delighted to have this opportunity, and it will be a pleasure to lead the laboratory through this next exciting phase of our growth and evolution.” 

Smith is leaving what is probably one of the more unusual laboratories, at a depth of 2km, SNOLAB is the deepest, cleanest laboratory in the world. (more information either at SNOLAB or its Wikipedia entry.)

Is Smith from the UK? Some clues

I found my subsequent clues on SNOLAB’s ‘bio’ page for Dr. Nigel Smith,

Nigel Smith joined SNOLAB as Director during July 2009. He currently holds a full Professorship at Laurentian University, adjunct Professor status at Queen’s University, and a visiting Professorial chair at Imperial College, London. He received his Bachelor of Science in physics from Leeds University in the U.K. in 1985 and his Ph. D. in astrophysics from Leeds in 1991. He has served as a lecturer at Leeds University, a research associate at Imperial College London, group leader (dark matter) and deputy division head at the STFC Rutherford Appleton Laboratory, before relocating to Canada to oversee the SNOLAB deep underground facility.

The answer would seem to be yes, Nigel James Telfer Smith is originally from the UK.

I don’t know if this is going to be a trend but this is the second ‘Nigel” to lead TRIUMF. (The Nigels are now tied with the Johns and the Alans. Of course, the letter ‘j’ seems the most popular with four names, John, John, Jack, and Jonathan.) Here’s a list of TRIUMF’s previous CEOs (from the TRIUMF Wikipedia entry),

Since its inception, TRIUMF has had eight directors [now nine] overseeing its operations.

The first Nigel (Lockyer) is described as an American in his Wikipedia entry. He was born in Scotland and raised in Canada. However, he has spent the majority of his adult life in the US, other than the five or six years at TRIUMF. So, previous Nigel also started life in the UK.

Good luck to the new Nigel.

UBC forestry professor, Suzanne Simard’s memoir going to the movies?

Given that Simard’s memoir, Finding the Mother Tree: Discovering the Wisdom of the Forest, was published last week on May 4, 2021, this is very heady news,. From a May 12, 2021 article by Cassandra Gill for the Daily Hive (Note: Links have been removed),

Jake Gyllenhaal is bringing the story of a UBC professor to the big screen.

The Oscar nominee’s production company, Nine Stories, is producing a film based on Suzanne Simard’s memoir, Finding the Mother Tree.

Amy Adams is set to play Simard, who is a forest ecology expert renowned for her research on plants and fungi.

Adams is also co-producing the film with Gyllenhaal through her own company, Bond Group Entertainment.

The BC native [Simard] developed an interest in trees and the outdoors through her close relationship with her grandfather, who was a horse logger.

Her 30 year career and early life is documented in the memoir, which was released last week on May 4 [2021]. Simard explores how trees have evolved, have memories, and are the foundation of our planet’s ecosystem — along with her own personal experiences with grief.

The scientists’ [sic] influence has had influence in popular culture, notably in James Cameron’s 2009 film Avatar. The giant willow-like “Tree of Souls” was specifically inspired by Simard’s work.

No mention of a script and no mention of financing, so, it could be a while before we see the movie on Netflix, Apple+, HBO, or maybe a movie house (if they’re open by then).

I think the script may prove to the more challenging aspect of this project. Here’s the description of Simard’s memoir (from the Finding the Mother Tree webpage on suzannesimard.com)

From the world’s leading forest ecologist who forever changed how people view trees and their connections to one another and to other living things in the forest–a moving, deeply personal journey of discovery.

About the Book

In her first book, Simard brings us into her world, the intimate world of the trees, in which she brilliantly illuminates the fascinating and vital truths – that trees are not simply the source of timber or pulp, but are a complex, interdependent circle of life; that forests are social, cooperative creatures connected through underground networks by which trees communicate their vitality and vulnerabilities with communal lives not that different from our own.

Simard writes – in inspiring, illuminating, and accessible ways – how trees, living side by side for hundreds of years, have evolved, how they perceive one another, learn and adapt their behaviors, recognize neighbors, and remember the past; how they have agency about the future; elicit warnings and mount defenses, compete and cooperate with one another with sophistication, characteristics ascribed to human intelligence, traits that are the essence of civil societies – and at the center of it all, the Mother Trees: the mysterious, powerful forces that connect and sustain the others that surround them.

How does Simard’s process of understanding trees and conceptualizing a ‘mother tree’ get put into a script for a movie that’s not a documentary or an animation?

Movies are moving pictures, yes? How do you introduce movement and action in a script heavily focused on trees, which operate on a timescale that’s vastly different.

It’s an interesting problem and I look forward to seeing how it’s resolved. I wish them good luck.

Why is Precision Nanosystems Inc. in the local (Vancouver, Canada) newspaper?

Usually when a company is featured in a news item, there’s some reason why it’s considered newsworthy. Even after reading the article twice, I still don’t see what makes the Precision Nanosystems Inc. (PNI) newsworthy.

Kevin Griffin’s Jan. 17, 2021 article about Vancouver area Precision Nanosystems Inc. (PNI) for The Province is interesting for anyone who’s looking for information about members of the local biotechnology and/or nanomedicine community (Note: Links have been removed),

A Vancouver nanomedicine company is part of a team using new genetic technology to develop a COVID-19 vaccine.

Precision NanoSystems Incorporated is working on a vaccine in the same class the ones made by Pfizer-BioNTech and Moderna, the only two COVID-19 vaccines approved by Health Canada.

PNI’s vaccine is based on a new kind of technology called mRNA which stands for messenger ribonucleic acid. The mRNA class of vaccines carry genetic instructions to make proteins that trigger the body’s immune system. Once a body has antibodies, it can fight off a real infection when it comes in contact with SARS-CoV-2, the name of the virus that causes COVID-19.

James Taylor, CEO of Precision NanoSystems, said the “revolutionary technology is having an impact not only on COVID-19 pandemic but also the treatment of other diseases.

The federal government has invested $18.2 million in PNI to carry its vaccine candidate through pre-clinical studies and clinical trails.

Ottawa has also invested another $173 million in Medicago, a Quebec-city based company which is developing a virus-like particle vaccine on a plant-based platform and building a large-scale vaccine and antibody production facility. The federal government has an agreement with Medicago to buy up to 76 million doses (enough for 38 million people) of its COVID-19 vaccine.

PNI’s vaccine, which the company is developing with other collaborators, is still at an early, pre-clinical stage.

Taylor is one of the co-founders of PNI along with Euan Ramsay, the company’s chief commercial officer.

The scientific co-founders of PNI are physicist Carl Hansen [emphasis mine] and Pieter Cullis. Cullis is also board chairman and scientific adviser at Acuitas Therapeutics [emphasis mine], the UBC biotechnology company that developed the delivery system for the Pfizer-BioNTech COVID-19 vaccine.

PNI, founded in 2010 as a spin-off from UBC [University of British Columbia], focuses on developing technology and expertise in genetic medicine to treat a wide range of infectious and rare diseases and cancers.

What has been described as PNI’s flagship product is a NanoAssemblr Benchtop Instrument, which allows scientists to develop nanomedicines for testing.

It’s informational but none of this is new, if you’ve been following developments in the COVID-19 vaccine story or local biotechnology scene. The $18.2 million federal government investment was announced in the company’s latest press release dated October 23, 2020. Not exactly fresh news.

One possibility is that the company is trying to generate publicity prior to a big announcement. As to why a reporter would produce this profile, perhaps he was promised an exclusive?

Acuitas Therapeutics, which I highlighted in the excerpt from Griffin’s story, has been featured here before in a November 12, 2020 posting about lipid nanoparticles and their role in the development of the Pfizer-BioNTech COVID-19 vaccine.

Curiously (or not), Griffin didn’t mention Vancouver’s biggest ‘COVID-19 star’, AbCellera. You can find out more about that company in my December 30, 2020 posting titled, Avo Media, Science Telephone, and a Canadian COVID-19 billionaire scientist, which features a link to a video about AbCellera’s work (scroll down about 60% of the way to the subsection titled: Avo Media, The Tyee, and Science Telephone, second paragraph).

The Canadian COVID-19 billionaire scientist? That would be Carl Hansen, Chief Executive Officer and co-founder of AbCellera and co-founder of PNI. it’s such a small world sometimes.

Avo Media, Science Telephone, and a Canadian COVID-19 billionaire scientist

I’ll start off with the COVID-19 billionaire since I imagine that excites the most interest.

AbCellera billionaire

No less an authority than the business magazine Forbes has produced a list of COVID-19 billionaires in its December 23, 2020 article (Meet The 50 Doctors, Scientists And Healthcare Entrepreneurs Who Became Pandemic Billionaires In 2020) by Giacomo Tognini (Note: Links have been removed),

Nearly a year after the first case of Covid-19 was reported in the Chinese city of Wuhan in December 2019, the world could be nearing the beginning of the end of a pandemic that has killed more than 1.7 million people. Vaccination for Covid-19 is underway in the United States and the United Kingdom, and promising antibody treatments could help doctors fight back against the disease more effectively. Tied to those breakthroughs: a host of new billionaires who have emerged in 2020, their fortunes propelled by a stock market surge as investors flocked to companies involved in the development of vaccines, treatments, medical devices and everything in between.

Altogether, Forbes found 50 new billionaires in the healthcare sector in 2020. …

Carl Hansen

Net worth: $2.9 billion

Citizenship: Canada

Source of wealth: AbCellera

Hansen is the CEO and cofounder of Vancouver-based AbCellera, a biotech firm that uses artificial intelligence and machine learning to identify the most promising antibody treatments for diseases. He founded the company in 2012. Until 2019 he also worked as a professor at the University of British Columbia, but shifted to focus full-time on AbCellera. That decision seems to have paid off, and Hansen’s 23% stake earned him a spot in the billionaire club after AbCellera’s successful listing on the Nasdaq on December 11. The U.S. government has ordered 300,000 doses of bamlanivimab, an antibody AbCellera discovered in partnership with Eli Lilly that received FDA approval as a Covid-19 treatment in November [2020].

Hansen was a professor at the University of British Columbia (UBC) where he founded AbCellera. From https://innovation.ubc.ca/about/news/spin-company-abcelleras-antibody-discovery-leads-covid-19-treatment (Note: A link has been removed),

AbCellera, a local biotechnology company founded at UBC, has developed a method that can search immune responses more deeply than any other technology. Using a microfluidic technology developed at the Michael Smith Laboratories, advanced immunology, protein chemistry, performance computing, and machine learning, AbCellera is changing the game for antibody therapeutics.

I believe a great deal of research that is commercialized was initially funded by taxpayers and I cannot recall any entrepreneurs here in Canada or elsewhere acknowledging that help in a big way. Should you be able to remember any comments of that type, please do let me know in the Comments.

Just prior to this financial bonanza, AbCellera was touting two new board members, John Montalbano on Nov. 18, 2020 and Peter Thiel on Nov. 19, 2020.

Here’s a bit about Mr. Montalbano from a Nov. 18, 2020 AbCellera news release (Note: A link has been removed),

November 18, 2020 – AbCellera, a technology company that searches, decodes, and analyzes natural immune systems to find antibodies that can be developed to prevent and treat disease, today announced the appointment of John Montalbano to its Board of Directors. Mr. Montalbano will serve as the Chair of the Audit Committee of the Board of Directors.

Mr. Montalbano is Principal of Tower Beach Capital Ltd. and serves on the boards of the Canada Pension Plan Investment Board, Aritzia Inc., and the Asia Pacific Foundation of Canada. His previous appointments include the former Vice Chair of RBC Wealth Management and CEO of RBC Global Asset Management (RBC GAM). When Mr. Montalbano retired as CEO of RBC GAM in 2015, it was among the largest 50 asset managers worldwide with $370 billion under management and offices in Canada, the United States, the United Kingdom, and Hong Kong.

Montalbano has been on this blog before in a Nov. 4, 2015 posting. If you scroll down to the subsection “Justin Trudeau and his British Columbia connection,” you’ll see mention of Montalbano’s unexpected exit as member and chair of UBC’s board of governors.

The next board member to hop on the proverbial path to riches was announced in a Nov. 19, 2020 AbCellera news release,

AbCellera, a technology company that searches, decodes, and analyzes natural immune systems to find antibodies that can be developed to prevent and treat disease, today announced the appointment of Peter Thiel to its Board of Directors.

“Peter has been a valued AbCellera investor and brings deep experience in scaling global technology companies,” said Carl Hansen, Ph.D., CEO of AbCellera. “We share his optimistic vision for the future, faith in technological progress, and long-term view on company building. We’re excited to have him join our board and look forward to working with him over the coming years.”

Mr. Thiel is a technology entrepreneur, investor, and author. He was a co-founder and CEO of PayPal, a company that he took public before it was acquired by eBay for $1.5 billion in 2002. Mr. Thiel subsequently co-founded Palantir Technologies in 2004, where he continues to serve as Chairman. As a technology investor, Mr. Thiel made the first outside investment in Facebook, where he has served as a director since 2005, and provided early funding for LinkedIn, Yelp, and dozens of technology companies. He is a partner at Founders Fund, a Silicon Valley venture capital firm that has funded companies including SpaceX and Airbnb.

“AbCellera is executing a long-term plan to make biotech move faster. I am proud to help them as they raise our expectations of what’s possible,” said Mr. Thiel.

Some Canadian business journalists got very excited over Thiel’s involvement in particular. Perhaps they were anticipating this December 10, 2020 AbCellera news release announcing an initial public offering. Much money seems to have been made not least for Mr. Montalbano, Mr. Thiel, and Mr. Hansen.

As for Mr. Thiel and taxes, I don’t know for certain but can infer that he’s not a big fan from this portion of his Wikipedia entry,

Thiel is an ideological libertarian,[108] though more recently he has espoused support for national conservatism[109] and criticized libertarian attitudes towards free trade[110] and big tech.[109]

My understanding is that libertarians object to taxes and prefer as little government structure as possible.

In any event, it seems that COVID-19 has been quite the bonanza for some people. If you’re curious you can find out more about AbCellera here.

Onto Avo Media and how it has contributed to the AbCellera story.

Avo Media, The Tyee, and Science Telephone

Vancouver (Canada)-based Avo Media describes itself this way on its homepage,

We make documentary, educational, and branded content.

We specialize in communicating science and other complex concepts in a clear, engaging way.

I think that description boils down to videos and podcasts. There’s no mention of AbCellera as one of their clients but they do list The Tyee, which in a July 1, 2020 posting (The Vancouver Company Turning Blood into a COVID Treatment: A Tyee Video) by Mashal Butt hosts a video about AbCellera,

The world anxiously awaits a vaccine to end the pandemic. But having a treatment could save countless lives in the meantime.

This Tyee video explains how Vancouver biotech company AbCellera, with funding from the federal government, is racing to develop an antibody-based therapy treatment as quickly as possible.

Experts — immunologist Ralph Pantophlet at Simon Fraser University, and co-founder and COO of AbCellera Véronique Lecault — explain what an antibody treatment is and how it can protect us from COVID-19.

It is not a cure, but it can help save lives as we wait for the cure.

This video was made in partnership with Vancouver’s Avo Media team of Jesse Lupini, Koby Michaels and Lucas Kavanagh.

It’s a video with a good explanation of AbCellera’s research. Interestingly, the script notes that the Canadian federal government gave the company over $175M for its COVID-19 work.

Why The Tyee?

While Avo Media is a local company, I notice that Jessica Yingling is listed in the final credits for the video. Yingling founded Little Dog Communications, which is based in both California and Utah. If you read the AbCellera news releases, you’ll see that she’s the media contact.

Is there a more unlikely media outlet to feature a stock market star, which probably will be making billions of dollars from this pandemic, than The Tyee? Politically, its ideology could be described as the polar opposite to libertarian ideology.

I wonder what the thought process was for the media placement and how someone based in San Diego (check out her self description on this Twitter feed @jyingling) came up with the idea?

Science Telephone

Avo Media’s latest project seems to be a podcast series, Science Telephone (this link is to the Spotify platform). Here’s more about the series and the various platforms where episodes can be found (from the Avo Media, Our Work, Science Telephone webpage) ,

Science Telephone is a new podcast that tests how well the science holds up when comedians get their hands onto it

Laugh while you learn, as the classic game of telephone is repurposed for scientific research. Each episode, one scientist explains their research to a comedian, who then has to explain it to the next comedian, and so on until it’s almost unrecognizable. See what sticks and what changes, with a rotating cast of brilliant scientists and hysterical comedians.

See a preview of the show below, or visit www.sciencetelephone.com to subscribe or listen to past episodes.

Science telephone is available on all the usual podcast platforms, including Apple Podcasts and Google Podcasts

I have included the Science Telephone preview here,

As we move towards the end of this year and this pandemic, it’s time to enjoy a little science comedy.

Arc’teryx performance apparel and University of British Columbia (Canada) scientists stay green and dry

As rainy season approaches in the Pacific Northwest of Canada and the US, there’s some good news about a sustainable water- and oil-repellent fabric. Sadly, it won’t be available this year but it’s something to look forward to.

An August 10, 2020 news item on phys.org announces the news from the University of British Columbia (UBC) about a greener, water-repellent fabric,

A sustainable, non-toxic and high-performance water-repellent fabric has long been the holy grail of outdoor enthusiasts and clothing companies alike. New research from UBC Okanagan and outdoor apparel giant Arc’teryx is making that goal one step closer to reality with one of the world’s first non-toxic oil and water-repellent performance textile finishes.

An August 10, 2020 UBC Okanagan news release (also on EurekAlert), which originated the news item, provides more detail,

Outdoor fabrics are typically treated with perfluorinated compounds (PFCs) to repel oil and water. But according to Sadaf Shabanian, doctoral student at UBC Okanagan’s School of Engineering and study lead author, PFCs come with a number of problems.

“PFCs have long been the standard for stain repellents, from clothing to non-stick frying pans, but we know these chemicals have a detrimental impact on human health and the environment,” explains Shabanian. “They pose a persistent, long-term risk to health and the environment because they take hundreds of years to breakdown and linger both in the environment and our bodies.”

According to Mary Glasper, materials developer at Arc’teryx and collaborator on the project, these lasting impacts are one of the major motivations for clothing companies to seek out new methods to achieve the same or better repellent properties in their products.

To solve the problem, Shabanian and the research team added a nanoscopic layer of silicone to each fibre in a woven fabric, creating an oil-repellent jacket fabric that repels water, sweat and oils.

By understanding how the textile weave and fibre roughness affect the liquid interactions, Shabanian says she was able to design a fabric finish that did not use any PFCs.

“The best part of the new design is that the fabric finish can be made from biodegradable materials and can be recyclable,” she says. “It addresses many of the issues related to PFC-based repellent products and remains highly suitable for the kind of technical apparel consumers and manufacturers are looking for.”

Arc’teryx is excited about the potential of this solution.

“An oil- and water-repellent finish that doesn’t rely on PFCs is enormously important in the world of textiles and is something the whole outdoor apparel industry has been working on for years,” says Glasper. “Now that we have a proof-of-concept, we’ll look to expand its application to other DWR-treated textiles used in our products and to improve the durability of the treatment.”

“Working to lessen material impacts on the environment is crucial for Arc’teryx to meet our goal of reducing our greenhouse gas emissions by 65 per cent in intensity by 2030,” she adds.

Kevin Golovin, principal investigator of the Okanagan Polymer Engineering Research & Applications Lab where the research was done, says the new research is important because it opens up a new area of green textile manufacturing.

He explains that while the new technology has immense potential, there are still several more years of development and testing needed before people will see fabrics with this treatment in stores.

“Demonstrating oil repellency without the use of PFCs is a critical first step towards a truly sustainable fabric finish,” says Golovin. “And it’s something previously thought impossible.”

The research is funded through a grant from the Natural Sciences and Engineering Research Council of Canada (NSERC), with support from Arc’teryx Equipment Inc.

Arc’teryx is based in North Vancouver (Canada).

Glass sponge reefs: ‘living dinosaurs’ of the Pacific Northwest waters

One of them looks to be screaming (Edvard Munch, anyone?) and none of it looks how I imagined an oceanic ‘living dinosaur’ might. While the news is not in my main area of interest (emerging technology), it is close to home. A June 1, 2020 University of British Columbia news release (also on EurekAlert) describes the glass sponge reefs (living dinosaurs) in the Pacific Northwest and current concerns about their welfare,

Warming ocean temperatures and acidification drastically reduce the skeletal strength and filter-feeding capacity of glass sponges, according to new UBC research.

The findings, published in Scientific Reports, indicate that ongoing climate change could have serious, irreversible impacts on the sprawling glass sponge reefs of the Pacific Northwest and their associated marine life – the only known reefs of their kind in the world.

Ranging from the Alaska-Canada border and down through the Strait of Georgia, the reefs play an essential role in water quality by filtering microbes and cycling nutrients through food chains. They also provide critical habitat for many fish and invertebrates, including rockfish, spot prawns, herring, halibut and sharks.

“Glass sponge reefs are ‘living dinosaurs’ thought to have been extinct for 40 million years before they were re-discovered in B.C. in 1986,” said Angela Stevenson, who led the study as a postdoctoral fellow at UBC Zoology. “Their sheer size and tremendous filtration capacity put them at the heart of a lush and productive underwater system, so we wanted to examine how climate change might impact their survival.”

Although the reefs are subject to strong, ongoing conservation efforts focused on limiting damage to their delicate glass structures, scientists know little about how these sponges respond to environmental changes.

For the study, Stevenson harvested Aphrocallistes vastus, one of three types of reef-building glass sponges, from Howe Sound and brought them to UBC where she ran the first successful long-term lab experiment involving live sponges by simulating their natural environment as closely as possible.

She then tested their resilience by placing them in warmer and more acidic waters that mimicked future projected ocean conditions.

Over a period of four months, Stevenson measured changes to their pumping capacity, body condition and skeletal strength, which are critical indicators of their ability to feed and build reefs.

Within one month, ocean acidification and warming, alone and in combination, reduced the sponges’ pumping capacity by more than 50 per cent and caused tissue losses of 10 to 25 per cent, which could starve the sponges.

“Most worryingly, pumping began to slow within two weeks of exposure to elevated temperatures,” said Stevenson.

The combination of acidification and warming also made their bodies weaker and more elastic by half. That could curtail reef formation and cause brittle reefs to collapse under the weight of growing sponges or animals walking and swimming among them.

Year-long temperature data collected from Howe Sound reefs in 2016 suggest it’s only a matter of time before sponges are exposed to conditions which exceed these thresholds.

“In Howe Sound, we want to figure out a way to track changes in sponge growth, size and area and area in the field so we can better understand potential climate implications at a larger scale,” said co-author Jeff Marliave, senior research scientist at the Ocean Wise Research Institute. “We also want to understand the microbial food webs that support sponges and how they might be influenced by climate cycles.”

Stevenson credits bottom-up community-led efforts and strong collaborations with government for the healthy, viable state of the B.C. reefs today. Added support for such community efforts and educational programs will be key to relieving future pressures.

“When most people think about reefs, they think of tropical shallow-water reefs like the beautiful Great Barrier Reef in Australia,” added Stevenson. “But we have these incredible deep-water reefs in our own backyard in Canada. If we don’t do our best to stand up for them, it will be like discovering a herd of dinosaurs and then immediately dropping dynamite on them.”

Background:

The colossal reefs can grow to 19 metres in height and are built by larval sponges settling atop the fused dead skeletons of previous generations. In northern B.C. the reefs are found at depths of 90 to 300 metres, while in southern B.C., they can be found as shallow as 22 metres.

The sponges feed by pumping sea water through their delicate bodies, filtering almost 80 per cent of microbes and particles and expelling clean water.

It’s estimated that the 19 known reefs in the Salish Sea can filter 100 billion litres of water every day, equivalent to one per cent of the total water volume in the Strait of Georgia and Howe Sound combined.

Here’s more about the painting, from The Scream webpage on edvardmunch.org,

Munch’s The Scream is an icon of modern art, the Mona Lisa for our time. As Leonardo da Vinci evoked a Renaissance ideal of serenity and self-control, Munch defined how we see our own age – wracked with anxiety and uncertainty.

Essentially The Scream is autobiographical, an expressionistic construction based on Munch’s actual experience of a scream piercing through nature while on a walk, after his two companions, seen in the background, had left him. …

For all the times I’ve seen the image, I had no idea the inspiration was acoustic.

In any event, the image seems sadly à propos both for the glass sponge reefs (and nature generally) and with regard to Black Lives Matter (BLM). A worldwide conflagration was ignited by George Floyd’s death in Minneapolis on May 25, 2020. This African-American man died while saying, “I can’t breathe,” as a police officer held Floyd down with a knee on his neck. RIP (rest in peace) George Floyd while the rest of us make the changes necessary, no matter how difficult to create a just and respectful world for all. Black Lives Matter.

Some amusements in the time of COVID-19

Gold stars for everyone who recognized the loose paraphrasing of the title, Love in the Time of Cholera, for Gabrial Garcia Marquez’s 1985 novel.

I wrote my headline and first paragraph yesterday and found this in my email box this morning, from a March 25, 2020 University of British Columbia news release, which compares times, diseases, and scares of the past with today’s COVID-19 (Perhaps politicians and others could read this piece and stop using the word ‘unprecedented’ when discussing COVID-19?),

How globalization stoked fear of disease during the Romantic era

In the late 18th and early 19th centuries, the word “communication” had several meanings. People used it to talk about both media and the spread of disease, as we do today, but also to describe transport—via carriages, canals and shipping.

Miranda Burgess, an associate professor in UBC’s English department, is working on a book called Romantic Transport that covers these forms of communication in the Romantic era and invites some interesting comparisons to what the world is going through today.

We spoke with her about the project.

What is your book about?

It’s about global infrastructure at the dawn of globalization—in particular the extension of ocean navigation through man-made inland waterways like canals and ship’s canals. These canals of the late 18th and early 19th century were like today’s airline routes, in that they brought together places that were formerly understood as far apart, and shrunk time because they made it faster to get from one place to another.

This book is about that history, about the fears that ordinary people felt in response to these modernizations, and about the way early 19th-century poets and novelists expressed and responded to those fears.

What connections did those writers make between transportation and disease?

In the 1810s, they don’t have germ theory yet, so there’s all kinds of speculation about how disease happens. Works of tropical medicine, which is rising as a discipline, liken the human body to the surface of the earth. They talk about nerves as canals that convey information from the surface to the depths, and the idea that somehow disease spreads along those pathways.

When the canals were being built, some writers opposed them on the grounds that they could bring “strangers” through the heart of the city, and that standing water would become a breeding ground for disease. Now we worry about people bringing disease on airplanes. It’s very similar to that.

What was the COVID-19 of that time?

Probably epidemic cholera [emphasis mine], from about the 1820s onward. The Quarterly Review, a journal that novelist Walter Scott was involved in editing, ran long articles that sought to trace the map of cholera along rivers from South Asia, to Southeast Asia, across Europe and finally to Britain. And in the way that its spread is described, many of the same fears that people are evincing now about COVID-19 were visible then, like the fear of clothes. Is it in your clothes? Do we have to burn our clothes? People were concerned.

What other comparisons can be drawn between those times and what is going on now?

Now we worry about the internet and “fake news.” In the 19th century, they worried about what William Wordsworth called “the rapid communication of intelligence,” which was the daily newspaper. Not everybody had access to newspapers, but each newspaper was read by multiple families and newspapers were available in taverns and coffee shops. So if you were male and literate, you had access to a newspaper, and quite a lot of women did, too.

Paper was made out of rags—discarded underwear. Because of the French Revolution and Napoleonic Wars that followed, France blockaded Britain’s coast and there was a desperate shortage of rags to make paper, which had formerly come from Europe. And so Britain started to import rags from the Caribbean that had been worn by enslaved people.

Papers of the time are full of descriptions of the high cost of rags, how they’re getting their rags from prisons, from prisoners’ underwear, and fear about the kinds of sweat and germs that would have been harboured in those rags—and also discussions of scarcity, as people stole and hoarded those rags. It rings very well with what the internet is telling us now about a bunch of things around COVID-19.

Plus ça change, n’est-ce pas?

And now for something completely different

Kudos to all who recognized the Monty Python reference. Now, onto the frogfish,

Thank you to the Monterey Bay Aquarium (in California, US).

A March 22, 2020 University of Washington (state) news release features an interview with the author of a new book on frogfishes,

Any old fish can swim. But what fish can walk, scoot, clamber over rocks, change color or pattern and even fight? That would be the frogfish.

The latest book by Ted Pietsch, UW professor emeritus of aquatic and fishery sciences, explores the lives and habits of these unusual marine shorefishes. “Frogfishes: Biodiversity, Zoogeography, and Behavioral Ecology” was published in March [2020] by Johns Hopkins University Press.

Pietsch, who is also curator emeritus of fishes at the Burke Museum of Natural History and Culture, has published over 200 articles and a dozen books on the biology and behavior of marine fishes. He wrote this book with Rachel J. Arnold, a faculty member at Northwest Indian College in Bellingham and its Salish Sea Research Center.

These walking fishes have stepped into the spotlight lately, with interest growing in recent decades. And though these predatory fishes “will almost certainly devour anything else that moves in a home aquarium,” Pietsch writes, “a cadre of frogfish aficionados around the world has grown within the dive community and among aquarists.” In fact, Pietsch said, there are three frogfish public groups on Facebook, with more than 6,000 members.

First, what is a frogfish?

Ted Pietsch: A member of a family of bony fishes, containing 52 species, all of which are highly camouflaged and whose feeding strategy consists of mimicking the immobile, inert, and benign appearance of a sponge or an algae-encrusted rock, while wiggling a highly conspicuous lure to attract prey.

This is a fish that “walks” and “hops” across the sea bottom, and clambers about over rocks and coral like a four-legged terrestrial animal but, at the same time, can jet-propel itself through open water. Some lay their eggs encapsulated in a complex, floating, mucus mass, called an “egg raft,” while some employ elaborate forms of parental care, carrying their eggs around until they hatch.

They are among the most colorful of nature’s productions, existing in nearly every imaginable color and color pattern, with an ability to completely alter their color and pattern in a matter of days or seconds. All these attributes combined make them one of the most intriguing groups of aquatic vertebrates for the aquarist, diver, and underwater photographer as well as the professional zoologist.

I couldn’t resist the ‘frog’ reference and I’m glad since this is a good read with a number of fascinating photographs and illustrations.,

Building with bacteria

A March 24, 2020 news item on phys.org features the future of building construction as perceived by synthetic biologists,

Buildings are not unlike a human body. They have bones and skin; they breathe. Electrified, they consume energy, regulate temperature and generate waste. Buildings are organisms—albeit inanimate ones.

But what if buildings—walls, roofs, floors, windows—were actually alive—grown, maintained and healed by living materials? Imagine architects using genetic tools that encode the architecture of a building right into the DNA of organisms, which then grow buildings that self-repair, interact with their inhabitants and adapt to the environment.

A March 23, 2020 essay by Wil Srubar (Professor of Architectural Engineering and Materials Science, University of Colorado Boulder), which originated the news item, provides more insight,

Living architecture is moving from the realm of science fiction into the laboratory as interdisciplinary teams of researchers turn living cells into microscopic factories. At the University of Colorado Boulder, I lead the Living Materials Laboratory. Together with collaborators in biochemistry, microbiology, materials science and structural engineering, we use synthetic biology toolkits to engineer bacteria to create useful minerals and polymers and form them into living building blocks that could, one day, bring buildings to life.

In one study published in Scientific Reports, my colleagues and I genetically programmed E. coli to create limestone particles with different shapes, sizes, stiffnesses and toughness. In another study, we showed that E. coli can be genetically programmed to produce styrene – the chemical used to make polystyrene foam, commonly known as Styrofoam.

Green cells for green building

In our most recent work, published in Matter, we used photosynthetic cyanobacteria to help us grow a structural building material – and we kept it alive. Similar to algae, cyanobacteria are green microorganisms found throughout the environment but best known for growing on the walls in your fish tank. Instead of emitting CO2, cyanobacteria use CO2 and sunlight to grow and, in the right conditions, create a biocement, which we used to help us bind sand particles together to make a living brick.

By keeping the cyanobacteria alive, we were able to manufacture building materials exponentially. We took one living brick, split it in half and grew two full bricks from the halves. The two full bricks grew into four, and four grew into eight. Instead of creating one brick at a time, we harnessed the exponential growth of bacteria to grow many bricks at once – demonstrating a brand new method of manufacturing materials.

Researchers have only scratched the surface of the potential of engineered living materials. Other organisms could impart other living functions to material building blocks. For example, different bacteria could produce materials that heal themselves, sense and respond to external stimuli like pressure and temperature, or even light up. If nature can do it, living materials can be engineered to do it, too.

It also take less energy to produce living buildings than standard ones. Making and transporting today’s building materials uses a lot of energy and emits a lot of CO2. For example, limestone is burned to make cement for concrete. Metals and sand are mined and melted to make steel and glass. The manufacture, transport and assembly of building materials account for 11% of global CO2 emissions. Cement production alone accounts for 8%. In contrast, some living materials, like our cyanobacteria bricks, could actually sequester CO2.

The field of engineered living materials is in its infancy, and further research and development is needed to bridge the gap between laboratory research and commercial availability. Challenges include cost, testing, certification and scaling up production. Consumer acceptance is another issue. For example, the construction industry has a negative perception of living organisms. Think mold, mildew, spiders, ants and termites. We’re hoping to shift that perception. Researchers working on living materials also need to address concerns about safety and biocontamination.

The [US] National Science Foundation recently named engineered living materials one of the country’s key research priorities. Synthetic biology and engineered living materials will play a critical role in tackling the challenges humans will face in the 2020s and beyond: climate change, disaster resilience, aging and overburdened infrastructure, and space exploration.

If you have time and interest, this is fascinating. Strubar is a little exuberant and, at this point, I welcome it.

Fitness

The Lithuanians are here for us. Scientists from the Kaunas University of Technology have just published a paper on better exercises for lower back pain in our increasingly sedentary times, from a March 23, 2020 Kaunas University of Technology press release (also on EurekAlert) Note: There are a few minor grammatical issues,

With the significant part of the global population forced to work from home, the occurrence of lower back pain may increase. Lithuanian scientists have devised a spinal stabilisation exercise programme for managing lower back pain for people who perform a sedentary job. After testing the programme with 70 volunteers, the researchers have found that the exercises are not only efficient in diminishing the non-specific lower back pain, but their effect lasts 3 times longer than that of a usual muscle strengthening exercise programme.

According to the World Health Organisation, lower back pain is among the top 10 diseases and injuries that are decreasing the quality of life across the global population. It is estimated that non-specific low back pain is experienced by 60% to 70% of people in industrialised societies. Moreover, it is the leading cause of activity limitation and work absence throughout much of the world. For example, in the United Kingdom, low back pain causes more than 100 million workdays lost per year, in the United States – an estimated 149 million.

Chronic lower back pain, which starts from long-term irritation or nerve injury affects the emotions of the afflicted. Anxiety, bad mood and even depression, also the malfunctioning of the other bodily systems – nausea, tachycardia, elevated arterial blood pressure – are among the conditions, which may be caused by lower back pain.

During the coronavirus disease (COVID-19) outbreak, with a significant part of the global population working from home and not always having a properly designed office space, the occurrence of lower back pain may increase.

“Lower back pain is reaching epidemic proportions. Although it is usually clear what is causing the pain and its chronic nature, people tend to ignore these circumstances and are not willing to change their lifestyle. Lower back pain usually comes away itself, however, the chances of the recurring pain are very high”, says Dr Irina Klizienė, a researcher at Kaunas University of Technology (KTU) Faculty of Social Sciences, Humanities and Arts.

Dr Klizienė, together with colleagues from KTU and from Lithuanian Sports University has designed a set of stabilisation exercises aimed at strengthening the muscles which support the spine at the lower back, i.e. lumbar area. The exercise programme is based on Pilates methodology.

According to Dr Klizienė, the stability of lumbar segments is an essential element of body biomechanics. Previous research evidence shows that in order to avoid the lower back pain it is crucial to strengthen the deep muscles, which are stabilising the lumbar area of the spine. One of these muscles is multifidus muscle.

“Human central nervous system is using several strategies, such as preparing for keeping the posture, preliminary adjustment to the posture, correcting the mistakes of the posture, which need to be rectified by specific stabilising exercises. Our aim was to design a set of exercises for this purpose”, explains Dr Klizienė.

The programme, designed by Dr Klizienė and her colleagues is comprised of static and dynamic exercises, which train the muscle strength and endurance. The static positions are to be held from 6 to 20 seconds; each exercise to be repeated 8 to 16 times.

The previous set is a little puzzling but perhaps you’ll find these ones below easier to follow,

I think more pictures of intervening moves would have been useful. Now. getting back to the press release,

In order to check the efficiency of the programme, 70 female volunteers were randomly enrolled either to the lumbar stabilisation exercise programme or to a usual muscle strengthening exercise programme. Both groups were exercising twice a week for 45 minutes for 20 weeks. During the experiment, ultrasound scanning of the muscles was carried out.

As soon as 4 weeks in lumbar stabilisation programme, it was observed that the cross-section area of the multifidus muscle of the subjects of the stabilisation group has increased; after completing the programme, this increase was statistically significant (p < 0,05). This change was not observed in the strengthening group.

Moreover, although both sets of exercises were efficient in eliminating lower back pain and strengthening the muscles of the lower back area, the effect of stabilisation exercises lasted 3 times longer – 12 weeks after the completion of the stabilisation programme against 4 weeks after the completion of the muscle strengthening programme.

“There are only a handful of studies, which have directly compared the efficiency of stabilisation exercises against other exercises in eliminating lower back pain”, says Dr Klizienė, “however, there are studies proving that after a year, lower back pain returned only to 30% of people who have completed a stabilisation exercise programme, and to 84% of people who haven’t taken these exercises. After three years these proportions are 35% and 75%.”

According to her, research shows that the spine stabilisation exercises are more efficient than medical intervention or usual physical activities in curing the lower back pain and avoiding the recurrence of the symptoms in the future.
