Not a pretty picture: Canada and a patent rights waiver for COVID-19 vaccines

At about 7:15 am PT this morning , May 13, 2021, I saw Dr. Mona Nemer’s (Canada’s Chief Science Advisor) tweet (Note: I’m sorry the formatting isn’t better,

Maryse de la Giroday@frogheart Does this mean Canada will support a waiver on patent rights for COVID-19 vaccines?

No reply. No surprise

Brief summary of Canada’s COVID-19 patent rights nonwaiver

You’ll find more about the UNESCO meeting on open science in last week’s May 7, 2021 posting (Listen in on a UNESCO (United Nations Educational, Scientific and Cultural Organization) meeting [about Open Science]).

At the time, I noted a disparity in Canada’s policies centering on open science and patents; scroll down to the “Comments on open science and intellectual property in Canada” subsection for a more nuanced analysis. For those who don’t have the patience and/or the time, it boils down to this:

  1. Canada is happily participating in a UNESCO meeting on open science,
  2. the 2021 Canadian federal budget just dedicated a big chunk of money to augmenting Canada’s national patent strategy, and
  3. Canada is “willing to discuss” a waiver at the World Trade Organization (WTO) meetings.

I predicted UNESCO would see our representative’s enthusiastic participation while our representative at the WTO meeting would dance around the topic without committing. to anything. Sadly, it’s starting to look like I was right.

Leigh Beadon in a May 12, 2021 posting on Techdirt reveals the situation is worse than I thought (Note: Links have been removed),

Few things illustrate the broken state of our global intellectual property system better than the fact that, well over a year into this devastating pandemic and in the face of a strong IP waiver push by some of the hardest hit countries, patents are still holding back the production of life-saving vaccines. And of all the countries opposing a waiver at the WTO (or withholding support for it, which is functionally the same thing), Canada might be the most frustrating [emphasis mine].

Canada is the biggest hoarder [emphasis mine] of vaccine pre-orders, having secured enough to vaccinate the population five times over. Despite this, it has constantly run into supply problems and lagged behind comparable countries when it comes to administering the vaccines on a per capita basis. In response to criticism of its hoarding, the government continues to focus on its plans to donate all surplus doses to the COVAX vaccine sharing program — but these promises were somewhat more convincing before Canada became the only G7 country to withdraw doses from COVAX. Despite all this, and despite pressure from experts who explain how vaccine hoarding will prolong the pandemic for everyone, the country has continually refused to voice its support for a TRIPS patent waiver at the WTO.

Momentum for changing Canada’s position on a COVID-19 vaccine patent right waivers?

Maclean’s magazine has a May 10, 2021 open letter to Prime Minister Justin Trudeau,

Dear Prime Minister Trudeau,

The only way to combat this pandemic successfully is through a massive global vaccination campaign on a scale and timeline never before undertaken. This requires the production of effective tools and technologies to fight COVID-19 at scale and coordinated global distribution efforts.

The Trade-Related Aspect of Intellectual Property Rights (TRIPS) agreement at the World Trade Organization (WTO) is leading to the opposite outcome. Vaccine production is hindered by granting pharmaceutical companies monopoly power through protection of intellectual property rights, industrial designs and trade secrets. Pharmaceutical companies’ refusal to engage in health technology knowledge transfer makes large-scale, global vaccine production in (and for) low- and middle-income countries all but impossible. The current distribution of vaccines globally speaks to these obstacles.

Hundreds of civil society groups, the World Health Organization (WHO), and the elected governments of over 100 countries, including India, Afghanistan, Bangladesh, Nepal, Pakistan and Sri Lanka have come together and stated that current intellectual property protections reduce the availability of vaccines for protecting their people. On May 5, 2021 the United States also announced its intention to support a temporary waiver for vaccines at the WTO.

We are writing to ask our Canadian government to demonstrate its commitment to an equitable global pandemic response by supporting a temporary waiver of the TRIPS agreement. But clearly that is a necessary but not a sufficient first step. We recognize that scaling up vaccine production requires more than just a waiver of intellectual property rights, so we further request that our government support the WHO’s COVID-19 Technology Access Pool (C-TAP) to facilitate knowledge sharing and work with the WTO to address the supply chain and export constraints currently impeding vaccine production. Finally, because vaccines must be rolled out as part of an integrated strategy to end the acute phase of the epidemic, we request that Canada support the full scope of the TRIPS waiver, which extends to all essential COVID-19 products and technologies, including vaccines, diagnostics and therapeutics.

The status quo is clearly not working fast enough to end the acute phase of the pandemic globally. This waiver respects global intellectual property frameworks and takes advantage of existing provisions for exceptions during emergencies, as enshrined in the TRIPS agreement. Empowering countries to take measures to protect their own people is fundamental to bringing this pandemic to an end.

Anand Giridharadas (author of the 2018 book, Winners Take All: The Elite Charade of Changing the World) also makes the case for a patent rights waiver in his May 11, 2021 posting on The Ink, Note: A link has been removed,

Patents are temporary monopolies granted to inventors, to reward invention and thus encourage more of it. But what happens when you invent a drug that people around the world require to stay alive? What happens when, furthermore, that drug was built in part on technology the public paid for? Are there limits to intellectual property?

For years, activists have pressured the United States government to break or suspend patents in particular cases, as with HIV/Aids. They have had little luck. Indeed, the United States has often fought developing countries when they try to break patents to do right by their citizens, choosing American drug companies over dying people.

So it was a dramatic swerve when, last week, the Biden administration announced that it supported a waiver of the patents for Covid vaccines.

Not long afterward, I reached out to several leading activists for vaccine access to understand the significance of the announcement and where we go from here.

in all this talk about patents and social justice and, whether it’s directly referenced or not, money, the only numbers of I’ve seen,until recently, have been numbers of doses and aggregate costs.

How much does a single vaccine dose cost?

A Sunday, April 11, 2021 article by Krassen Nikolov for EURACTIV provides an answer about the cost in one region, the European Union,

“Pfizer cost €12, then €15.50. The Commission now signs contracts for €19,50”, Bulgarian Prime Minister Boyko Borissov revealed on Sunday [April 11, 2021].

The European Commission is in talks with Pfizer for the supply of COVID-19 vaccines in 2022 and 2023. Borissov said the contracts provide for €19.50 per dose.

Under an agreement with the vaccine producing companies, the European Commission has so far refused to reveal the price of vaccines. However, last December Belgian Secretary of State Eva De Bleeker shared on Twitter the vaccine prices negotiated by the Commission, as well as the number of doses purchased by her government. Then, it became known that the AstraZeneca jab costs €1.78 compared to €12 for Pfizer-BioNTech.

€12 to €19,50, that’s an increase of over 50%. I wonder how Pfizer is justifying such a hefty increase?

According to a March 16, 2021 article by Swikar Oli for the National Post (a Canadian newspaper), these prices are a cheap pandemic special prices,

A top Pfizer executive told shareholders the company is looking at a “significant opportunity” to raise the price of its Pfizer-BioNTech COVID-19 vaccine.

While addressing investors at the virtual Barclays Global Healthcare Conference last week, Pfizer CFO Frank D’Amelio noted they could raise prices when the virus becomes endemic, meaning it’s regularly found in clusters around the globe, according to a transcript of the conference posted on Pfizer’s website.

Current vaccine pricing models are pandemic-related, D’Amelio explained. After the pandemic is defeated and “normal market conditions” arrive, he noted the window would open for a “significant opportunity…from a pricing perspective.”

“So the one price that we published is the price with the U.S. of $19.50 per dose. Obviously, that’s not a normal price like we typically get for a vaccine, $150, $175 [emphasis mine] per dose,” he said, “So pandemic pricing.”

If I remember it rightly, as you increase production, you lower costs per unit. In other words, it’s cheaper to produce one dozen than one, which is why your bakery charges you less money per bun or cake if you purchase by the dozen.

During this pandemic, Pfizer has been producing huge amounts of vaccine, which they would not expect to do should the disease become endemic. As Pfizer has increased production, I would think the price should be dropping but according to the Bulgarian prime minister, it’s not.

They don’t seem to be changing the vaccine as new variants arrive. So, raising the prices doesn’t seem to be linked to research issues and as for the new production facilities, surely those didn’t cost billions.

Canada and COVID-19 money

Talking about money, Canada has a COVDI-19 billionaire according to a December 23, 2020 article (Meet The 50 Doctors, Scientists And Healthcare Entrepreneurs Who Became Pandemic Billionaires In 2020) by Giacomo Tognini for Forbes.

I have a bit more about Carl Hansen (COVID-19 billionaire) and his company, AbCellera, in my December 30, 2020 posting.

I wonder how much the Canadian life sciences community has to do with Canada’s hesitancy over a COVID-19 vaccine patent rights waiver.

‘Greener’ lithium mining in Canada

A February 19, 2021 article by Pamela Fieber for CBC (Canadian Broadcasting Corporation) news online features news of a Calgary (Alberta) company, Summit Nanotech, and a greener way to mine lithium (Note: A link has been removed),

Amanda Hall was on top of a mountain in Tibet when inspiration struck. 

“I saw a Tibetan monk reach into his robe and pull out an iPhone,” Hall told the Calgary Eyeopener [CBC radio programme].

“If there’s an iPhone at the top of a mountain in Tibet, where isn’t there an iPhone on this planet? And then it just got me thinking about batteries and battery technology and energy and how we store that energy.”

On her return to Calgary, the accomplished geophysicist began looking into a better, greener way to mine lithium — the essential ingredient in lithium-ion batteries, which power electric cars and smartphones.

This led to her founding the company, Summit Nanotech in 2018 and developing nanotechnology, which works with materials at the molecular or atomic level to selectively filter lithium out of the wasted saltwater brine used in oil wells.

It’s completely different from the way lithium is traditionally mined.

Sarah Offin’s November 12, 2020 article for Global TV News offers insight into the technology developed by Hall’s company (Note: Links have been removed),

Since the downturn in the oil and gas industry, there have been repeated calls for Alberta to diversify its economy. The province invests hundreds of millions of dollars every year to help grow both the tech and green energy sectors, industries that could have a bright future in a province rich with talent.

Amanda Hall is a prime example of that. She was able to draw on her experience in resource extraction with Alberta’s oil and gas industry, developing green technology to be used in energy storage.

Hall developed the only female-led mining technology company in the world: Summit Nanotech Corp. Using nanotechnology, Hall and her team say they have created an improved method of lithium-ion resource extraction from produced brine water.

“We’ve come up with a much more elegant approach — I say, feminine, approach — at bringing a resource out of the ground, and then giving it to the electric vehicle sector,” Hall said.

Using sponges developed through nanoscience, Hall and her team have created technology that will allow producers to extract lithium directly from the wellhead without the need for expansive ponds and toxic chemicals. The process is expected to reduce costs and decrease chemical waste by 90 per cent.

The firm’s website touts that its process is the most “green lithium extraction in the world.”

“The sponge has lithium selective cavities in it, just the exact size of a lithium-ion. And so, as if you put a fluid in against this sponge, it will only suck up lithium, nothing else, and it holds on to it. And then when you wash it, you wash the lithium off the sponge just by changing the environment it’s in. So we don’t have to use any acids,” Hall said.

Hall and her team have spent the last two-and-a-half years in the lab perfecting their design and are now building the company’s first full-scale 12-metre tall unit. “It’s our baby, but it’s huge,” Hall said. “It’s a mini-refinery, essentially.”

That “mini-refinery” will then be sent via shipping container to the first of the company’s three pilot partners: Lithium Chile.

The other two partners are Saskatchewan-based Prairie Lithium and 3 Proton Lithium (3PL) Operating Inc. in Nevada.

For anyone interested in the business and investment aspects (there’s mention of Elon Musk in both stories) check out Fieber’s February 19, 2021 article and Offin’s November 12, 2020 article.

You can find Summit Nanotech here. I found a little more information about the company’s technology on the Lithium webpage,

denaLi 1.0
Direct Lithium Extraction
(DLE) Process

Summit Nanotech has designed an innovative new method to generate battery grade lithium compounds from brine fluids, named denaLi. This process is the most green lithium extraction technology in the world. Lithium carbonate and lithium hydroxide can be sold at market value to supply the growing demand from electric vehicle battery manufacturers. 

Interconnected modules using nanoporous membranes in a unique arrangement are synthesized with specific filtration functions. Carbon dioxide is used to initiate end product precipitation. Discrete power generation modules are selected to work together to harvest and store available geothermal, solar, wind, and hydroelectric power from the system’s environment.

Prairie Lithium, the Saskatchewan-based company mentioned in Offin’s article, co-founded a joint venture specifically dedicated to lithium extraction from brine (to begin with) in 2020 according to Jonathan Guignard in a June 3, 2020 article for Global TV news (Note: Links have been removed),

Saskatchewan will soon be home to a new lithium production project.

The Prairie-LiEP Critical Mineral (PLCM) joint venture is being undertaken by Prairie Lithium Corp. and LiEP Energy Ltd [headquarted in Calgary, Alberta].

Their two-stage pilot project will produce lithium hydroxide from some of the province’s oilfield brines.

The first stage of the project is based in Regina and is set to being in July. The second stage is set for the second half of 2021, with field operations in southern parts of the province.

“PLCM Joint Venture is excited to begin Stage 1 of the pilot operation in Saskatchewan this summer,” said Prairie president and CEO Zach Maurer and LiEP president and CEO Haafiz Hasham.

I can’t find any mention of the PLCM joint venture on the Prairie Lithium website but there is what appears to be a June 3, 2020 news release announcing the venture on the LiEP Energy website but there is no further information on that website.

On another front, Lithium Chile, which seems to be headquartered in Calgary with extensive lithium mining projects in Chile, has a brief mention of their partnership with Summit Nanotech in a December 24, 2020 posting (on the News webpage) by Steve (Cochrane; president and chief executive officer),

Lastly our partnership with Summit continues to move forward and we are very happy to be working with them. I have attached our recently negotiated LOI [letter of intent] for our JV [joint venture] pilot project in Chile. We should have the definitive agreement signed early in the new year. They plan to have their pilot unit completed and shipped by July of 2021 so a planned test is scheduled for late summer next year. This gives us the time to get back on one or more of our lithium prospects to prepare for our pilot project. They continue to see great results in the lab and hope this is the breakthrough we all want to see for an efficient cost and environmentally effective method of producing lithium from brines.

I cannot find any further mention on the Lithium Chile website about their joint venture with Summit Nanotech.

The big question is whether or not this technology can be scaled for industrial use. I wish them good luck with the effort.

All this talk about lithium extraction and other natural resource extraction brought to mind Harold Innis and his staples theory of Canadian history, culture, and economy. From the Harold Innis Wikipedia entry (Note: Links have been removed),

Harold Adams Innis FRSC (1894 – 1952) was a Canadian professor of political economy at the University of Toronto and the author of seminal works on media, communication theory, and Canadian economic history. He helped develop the staples thesis, [emphasis mine] which holds that Canada’s culture, political history, and economy have been decisively influenced by the exploitation and export of a series of “staples” such as fur, fishing, lumber, wheat, mined metals [emphasis mine], and coal. The staple thesis dominated economic history in Canada from the 1930s to 1960s, and continues to be a fundamental part of the Canadian political economic tradition.[8]

There you have it.

Mite silk as the basis for a new nanobiomaterial

For the record, this is spider mite silk (I have many posts about spider silk and its possible applications on this blog; just search ‘spider silk’)..

The international collaborative team includes a Canadian university in combination with a Spanish university and a Serbian university. The composition of the team is one I haven’t seen here before. From a December 17, 2020 news item on phys.org (Note: A link has been removed),

An international team of researchers has developed a new nanomaterial from the silk produced by the Tetranychus lintearius mite. This nanomaterial has the ability to penetrate human cells without damaging them and, therefore, has “promising biomedical properties”.

The Nature Scientific Reports journal has published an article by an international scientific team led by Miodrag Grbiç, a researcher from the universities of La Rioja (Spain), Western Ontario (Canada) and Belgrade (Serbia), in its latest issue entitled “The silk of gorse spider mite Tetranychus lintearius represents a novel natural source of nanoparticles and biomaterials.”

In it, researchers from the Murcian Institute for Agricultural and Food Research and Development (IMIDA), the Barcelona Institute of Photonic Sciences, the University of Western Ontario (Canada), the University of Belgrade (Serbia) and the University of La Rioja describe the discovery and characterisation of this mite silk. They also demonstrate its great potential as a source of nanoparticles and biomaterials for medical and technological uses.

A December 17, 2020 Universidad de La Rioja press release (also on EurekAlert), which originated the news item, further explains the research,

The interest of this new material, which is more resistant than steel, ultra flexible, nano-sized, biodegradable, biocompatible and has an excellent ability to penetrate human cells without damaging them, lies in its natural character and its size (a thousand times smaller than human hair), which facilitates cell penetration.

These characteristics are ideal for use in pharmacology and biomedicine since it is biocompatible with organic tissues (stimulates cell proliferation without producing toxicity) and, in principle, biodegradable due to its protein structure (it does not produce residues).

Researcher Miodrag Grbi?, who heads the international group that has researched this mite silk, highlights “its enormous potential for biomedical applications, as thanks to its size it is able to easily penetrate both healthy and cancerous human cells”, which makes it ideal for transporting drugs in cancer therapies, as well as for the development of biosensors to detect pathogens and viruses.

THE ‘RIOJANO BUG’

Tetranychus lintearius is an endemic mite from the European Atlantic coast that feeds exclusively on gorse (Ulex europaeus). It is around 0.3 mm in size, making it smaller than the comma on a keyboard, while the strength of its silk is twice as high as standard spider silk.

It is a very rare species that has only been found so far in the municipality of Valgañón (La Rioja, Spain), in Sierra de la Demanda. It was located thanks to the collaboration of Rosario García, a botanist and former dean of the Faculty of Science and Technology at the University of La Rioja, which is why researchers call it “the Rioja bug” (“El Bicho Riojano”).

The resistance of the silk produced by Tetranychus lintearius is twice that of spider silk, a standard material used for this type of research, and stronger than steel. It also has advantages over the fibres secreted by the silkworm due to its higher Young’s modulus, its electrical charge and its smaller size. These characteristics, along with its lightness, make it a promising natural nanomaterial for technological uses.

This finding is the result of work carried out by the international group of researchers led by Miodrag Grbi?, who sequenced the genome of the red spider Tetranychus urticae in 2011, publishing the results in Nature: https://www.nature.com/articles/nature10640.

Unlike the red spider (Tetranychus urticae), the gorse mite (Tetranychus lintearius) produces a large amount of silk. It has been reared in the laboratories of the Department of Agriculture and Food of the University of La Rioja, under the care of Professor Ignacio Pérez Moreno, allowing research to continue. Red spider silk is difficult to handle and has a lower production rate.

How do viruses and physics go together? Find out at a Nov. 4, 2020 Perimeter Institute (PI) virtual lecture

I got this announcement from an Oct. 29, 2020 Perimeter Institute (PI) Emmy Noether newsletter (received via email),

Catherne Beauchemin

A Physicist’s Adventures in Virology WEDNESDAY, NOVEMBER 4 at 7 pm ET [4 pm PT]

In recent years, there has been a rise in cynicism about many traditionally well-respected institutions – science, academia, news reporting, and even the concepts of experts and expertise more generally. Many people’s primary – or only – exposure to science is through biological or health science, especially during the COVID-19 pandemic.

In health research, rising cynicism has spawned the anti-vaccine movement, and a growing reliance on advice from peer networks rather than experts. In part, such movements are fuelled by several examples of provably false, so-called “scientific results,” coming about either through fraud or incompetence. While skepticism is crucial to science, cynicism rooted in a lack of trust can devalue scientific contributions.

In her lecture webcast, physicist Catherine Beauchemin will explore the erosion of trust in health research, presenting examples from influenza and COVID-19. …

I went to the A Physicist’s Adventures in Virology event and livestrream page to find this,

Two essential ingredients of the scientific method are skepticism and independent confirmation – the ability to glean for oneself whether an established theory or a new hypothesis is true or false. But not everyone has the capacity to perform the experiments to obtain such a confirmation.

Consider, for example, the costs of constructing your own Large Hadron Collider, or your ability as a non-expert to critically read and understand a scientific publication. In practice, acceptance of scientific theories is more often based on trust than on independent confirmation. When that trust is eroded, issues emerge.

Catherine Beauchemin is a Professor of Physics at Ryerson University and a Deputy Program Director in the RIKEN Interdisciplinary Theoretical and Mathematical Sciences Program in Japan. For the last 18 years, she has been developing mathematical and computational descriptions of how viruses spread from cell to cell, a field she calls “virophysics.”

In her November 4 [2020] Perimeter Public Lecture webcast, Beauchemin will highlight some of the issues that have eroded trust in health research, presenting examples from influenza and COVID-19. She will show why she believes many of these issues have their root in the fact that hypotheses in health research are formulated as words rather than mathematical expressions – and why a dose of physics may be just the prescription we need.

Enjoy!

The Quantum Physicist as Causal Detective: an Oct. 7, 2020 event

I love mysteries and am quite interested in the nature of reality (you, too?) and that gives us something in common with a couple of Perimeter Institute for Theoretical Physics (PI; Canada) researchers. From The Quantum Physicist as Causal Detective event page on the insidetheperimeter.ca website (notice received via email),

In their live webcast from Perimeter on October 7 [2020], Robert Spekkens and Elie Wolfe will shed light on the exciting possibilities brought about by applying quantum thinking to the science of cause and effect.

Watch the live webcast on this page on Wednesday, October 7 [2020] at 7 pm ET.

What do data science and the foundations of quantum theory have to do with one another?

A great deal, it turns out. The particular branch of data science known as causal inference focuses on a problem which is central to disciplines ranging from epidemiology to economics: that of disentangling correlation and causation in statistical data.

Meanwhile, in a slightly different guise, this same problem has been pondered by quantum physicists as part of a continuing effort to make sense of various puzzling quantum phenomena. On top of that, the most celebrated result concerning quantum theory’s meaning for the nature of reality – Bell’s theorem – can be seen in retrospect to be built on the solution to a particularly challenging problem in causal inference.

Recent efforts to elaborate upon these connections have led to an exciting flow of techniques and insights across the disciplinary divide.

Perimeter researchers Robert Spekkens and Elie Wolfe have done pioneering work studying relations of cause and effect through a quantum foundational lens, and can be counted among a small number of physicists worldwide with expertise in this field.

In their joint webcast from Perimeter [at 7 pm ET] on October 7 [2020], Spekkens and Wolfe will explore what is happening at the intersection of these two fields and how thinking like a quantum physicist leads to new ways of sussing out cause and effect from correlation patterns in statistical data.

For those of us on the West Coast, that webcast will be at 4 p.m. on Wednesday, Oct. 7, 2020 and I believe you can watch it here.

News from the Canadian Light Source (CLS), Canadian Science Policy Conference (CSPC) 2020, the International Symposium on Electronic Arts (ISEA) 2020, and HotPopRobot

I have some news about conserving art; early bird registration deadlines for two events, and, finally, an announcement about contest winners.

Canadian Light Source (CLS) and modern art

Rita Letendre. Victoire [Victory], 1961. Oil on canvas, Overall: 202.6 × 268 cm. Art Gallery of Ontario. Gift of Jessie and Percy Waxer, 1974, donated by the Ontario Heritage Foundation, 1988. © Rita Letendre L74.8. Photography by Ian Lefebvre

This is one of three pieces by Rita Letendre that underwent chemical mapping according to an August 5, 2020 CLS news release by Victoria Martinez (also received via email),

Research undertaken at the Canadian Light Source (CLS) at the University of Saskatchewan was key to understanding how to conserve experimental oil paintings by Rita Letendre, one of Canada’s most respected living abstract artists.

The work done at the CLS was part of a collaborative research project between the Art Gallery of Ontario (AGO) and the Canadian Conservation Institute (CCI) that came out of a recent retrospective Rita Letendre: Fire & Light at the AGO. During close examination, Meaghan Monaghan, paintings conservator from the Michael and Sonja Koerner Centre for Conservation, observed that several of Letendre’s oil paintings from the fifties and sixties had suffered significant degradation, most prominently, uneven gloss and patchiness, snowy crystalline structures coating the surface known as efflorescence, and cracking and lifting of the paint in several areas.

Kate Helwig, Senior Conservation Scientist at the Canadian Conservation Institute, says these problems are typical of mid-20th century oil paintings. “We focused on three of Rita Letendre’s paintings in the AGO collection, which made for a really nice case study of her work and also fits into the larger question of why oil paintings from that period tend to have degradation issues.”

Growing evidence indicates that paintings from this period have experienced these problems due to the combination of the experimental techniques many artists employed and the additives paint manufacturers had begun to use.

In order to determine more precisely how these factors affected Letendre’s paintings, the research team members applied a variety of analytical techniques, using microscopic samples taken from key points in the works.

“The work done at the CLS was particularly important because it allowed us to map the distribution of materials throughout a paint layer such as an impasto stroke,” Helwig said. The team used Mid-IR chemical mapping at the facility, which provides a map of different molecules in a small sample.

For example, chemical mapping at the CLS allowed the team to understand the distribution of the paint additive aluminum stearate throughout the paint layers of the painting Méduse. This painting showed areas of soft, incompletely dried paint, likely due to the high concentration and incomplete mixing of this additive. 

The painting Victoire had a crumbling base paint layer in some areas and cracking and efflorescence at the surface in others.  Infrared mapping at the CLS allowed the team to determine that excess free fatty acids in the paint were linked to both problems; where the fatty acids were found at the base they formed zing “soaps” which led to crumbling and cracking, and where they had moved to the surface they had crystallized, causing the snowflake-like efflorescence.

AGO curators and conservators interviewed Letendre to determine what was important to her in preserving and conserving her works, and she highlighted how important an even gloss across the surface was to her artworks, and the philosophical importance of the colour black in her paintings. These priorities guided conservation efforts, while the insights gained through scientific research will help maintain the works in the long term.

In order to restore the black paint to its intended even finish for display, conservator Meaghan Monaghan removed the white crystallization from the surface of Victoire, but it is possible that it could begin to recur. Understanding the processes that lead to this degradation will be an important tool to keep Letendre’s works in good condition.

“The world of modern paint research is complicated; each painting is unique, which is why it’s important to combine theoretical work on model paint systems with this kind of case study on actual works of art” said Helwig. The team hopes to collaborate on studying a larger cross section of Letendre’s paintings in oil and acrylic in the future to add to the body of knowledge.

The preliminary programme can be found here. This year there will be some discussion of a Canadian synthetic biology roadmap, presentations on various Indigenous concerns (mostly health), a climate challenge presentation focusing on Mexico and social vulnerability and another on parallels between climate challenges and COVID-19. There are many presentations focused on COVID-19 and.or health.

There doesn’t seem to be much focus on cyber security and, given that we just lost two ice caps (see Brandon Spektor’s August 1, 2020 article [Two Canadian ice caps have completely vanished from the Arctic, NASA imagery shows] on the Live Science website), it’s surprising that there are no presentations concerning the Arctic.

International Symposium on Electronic Arts (ISEA) 2020

According to my latest information, the early bird rate for ISEA 2020 (Oct. 13 -18) ends on August 13, 2020. (My June 22, 2020 posting describes their plans for the online event.)

You can find registration information here.

Margaux Davoine has written up a teaser for the 2020 edition of ISEA in the form of an August 6, 2020 interview with Yan Breuleux. I’ve excerpted one bit,

Finally, thinking about this year’s theme [Why Sentience?], there might be something a bit ironic about exploring the notion of sentience (historically reserved for biological life, and quite a small subsection of it) through digital media and electronic arts. There’s been much work done in the past 25 years to loosen the boundaries between such distinctions: how do you imagine ISEA2020 helping in that?

The similarities shared between humans, animals, and machines are fundamental in cybernetic sciences. According to the founder of cybernetics Norbert Wiener, the main tenets of the information paradigm – the notion of feedback – can be applied to humans, animals as well as the material world. Famously, the AA predictor (as analysed by Peter Galison in 1994) can be read as a first attempt at human-machine fusion (otherwise known as a cyborg).

The infamous Turing test also tends to blur the lines between humans and machines, between language and informational systems. Second-order cybernetics are often associated with biologists Francisco Varela and Humberto Maturana. The very notion of autopoiesis (a system capable of maintaining a certain level of stability in an unstable environment) relates back to the concept of homeostasis formulated by Willam Ross [William Ross Ashby] in 1952. Moreover, the concept of “ecosystems” emanates directly from the field of second-order cybernetics, providing researchers with a clearer picture of the interdependencies between living and non-living organisms. In light of these theories, the absence of boundaries between animals, humans, and machines constitutes the foundation of the technosciences paradigm. New media, technological arts, virtual arts, etc., partake in the dialogue between humans and machines, and thus contribute to the prolongation of this paradigm. Frank Popper nearly called his book “Techno Art” instead of “Virtual Art”, in reference to technosciences (his editor suggested the name change). For artists in the technological arts community, Jakob von Uexkull’s notion of “human-animal milieu” is an essential reference. Also present in Simondon’s reflections on human environments (both natural and artificial), the notion of “milieu” is quite important in the discourses about art and the environment. Concordia University’s artistic community chose the concept of “milieu” as the rallying point of its research laboratories.

ISEA2020’s theme resonates particularly well with the recent eruption of processing and artificial intelligence technologies. For me, Sentience is a purely human and animal idea: machines can only simulate our ways of thinking and feeling. Partly in an effort to explore the illusion of sentience in computers, Louis-Philippe Rondeau, Benoît Melançon and I have established the Mimesis laboratory at NAD University. Processing and AI technologies are especially useful in the creation of “digital doubles”, “Vactors”, real-time avatar generation, Deep Fakes and new forms of personalised interactions.

I adhere to the epistemological position that the living world is immeasurable. Through their ability to simulate, machines can merely reduce complex logics to a point of understandability. The utopian notion of empathetic computers is an idea mostly explored by popular science-fiction movies. Nonetheless, research into computer sentience allows us to devise possible applications, explore notions of embodiment and agency, and thereby develop new forms of interaction. Beyond my own point of view, the idea that machines can somehow feel emotions gives artists and researchers the opportunity to experiment with certain findings from the fields of the cognitive sciences, computer sciences and interactive design. For example, in 2002 I was particularly marked by an immersive installation at Universal Exhibition in Neuchatel, Switzerland titled Ada: Intelligence Space. The installation comprised an artificial environment controlled by a computer, which interacted with the audience on the basis of artificial emotion. The system encouraged visitors to participate by intelligently analysing their movements and sounds. Another example, Louis-Philippe Demers’ Blind Robot (2012),  demonstrates how artists can be both critical of, and amazed by, these new forms of knowledge. Additionally, the 2016 BIAN (Biennale internationale d’art numérique), organized by ELEKTRA (Alain Thibault) explored the various ways these concepts were appropriated in installation and interactive art. The way I see it, current works of digital art operate as boundary objects. The varied usages and interpretations of a particular work of art allow it to be analyzed from nearly every angle or field of study. Thus, philosophers can ask themselves: how does a computer come to understand what being human really is?

I have yet to attend conferences or exchange with researchers on that subject. Although the sheer number of presentation propositions sent to ISEA2020, I have no doubt that the symposium will be the ideal context to reflect on the concept of Sentience and many issues raised therein.

For the last bit of news.

HotPopRobot, one of six global winners of 2020 NASA SpaceApps COVID-19 challenge

I last wrote about HotPopRobot’s (Artash and Arushi with a little support from their parents) response to the 2020 NASA (US National Aeronautics and Space Administration) SpaceApps challenge in my July 1, 2020 post, Toronto COVID-19 Lockdown Musical: a data sonification project from HotPopRobot. (You’ll find a video of the project embedded in the post.)

Here’s more news from HotPopRobot’s August 4, 2020 posting (Note: Links have been removed),

Artash (14 years) and Arushi (10 years). Toronto.

We are excited to become the global winners of the 2020 NASA SpaceApps COVID-19 Challenge from among 2,000 teams from 150 countries. The six Global Winners will be invited to visit a NASA Rocket Launch site to view a spacecraft launch along with the SpaceApps Organizing team once travel is deemed safe. They will also receive an invitation to present their projects to NASA, ESA [European Space Agency], JAXA [Japan Aerospace Exploration Agency], CNES [Centre National D’Etudes Spatiales; France], and CSA [Canadian Space Agency] personnel. https://covid19.spaceappschallenge.org/awards

15,000 participants joined together to submit over 1400 projects for the COVID-19 Global Challenge that was held on 30-31 May 2020. 40 teams made to the Global Finalists. Amongst them, 6 teams became the global winners!

The 2020 SpaceApps was an international collaboration between NASA, Canadian Space Agency, ESA, JAXA, CSA,[sic] and CNES focused on solving global challenges. During a period of 48 hours, participants from around the world were required to create virtual teams and solve any of the 12 challenges related to the COVID-19 pandemic posted on the SpaceApps website. More details about the 2020 SpaceApps COVID-19 Challenge:  https://sa-2019.s3.amazonaws.com/media/documents/Space_Apps_FAQ_COVID_.pdf

We have been participating in NASA Space Challenge for the last seven years since 2014. We were only 8 years and 5 years respectively when we participated in our very first SpaceApps 2014.

We have grown up learning more about space, tacking global challenges, making hardware and software projects, participating in meetings, networking with mentors and teams across the globe, and giving presentations through the annual NASA Space Apps Challenges. This is one challenge we look forward to every year.

It has been a fun and exciting journey meeting so many people and astronauts and visiting several fascinating places on the way! We hope more kids, youths, and families are inspired by our space journey. Space is for all and is yours to discover!

If you have the time, I recommend reading HotPopRobot’s August 4, 2020 posting in its entirety.

Canadian and Italian researchers go beyond graphene with 2D polymers

According to a May 20,2020 McGill University news release (also on EurkekAltert), a team of Canadian and Italian researchers has broken new ground in materials science (Note: There’s a press release I found a bit more accessible and therefore informative coming up after this one),

A study by a team of researchers from Canada and Italy recently published in Nature Materials could usher in a revolutionary development in materials science, leading to big changes in the way companies create modern electronics.

The goal was to develop two-dimensional materials, which are a single atomic layer thick, with added functionality to extend the revolutionary developments in materials science that started with the discovery of graphene in 2004.

In total, 19 authors worked on this paper from INRS [Institut National de la Recherche Scientifique], McGill {University], Lakehead [University], and Consiglio Nazionale delle Ricerche, the national research council in Italy.

This work opens exciting new directions, both theoretical and experimental. The integration of this system into a device (e.g. transistors) may lead to outstanding performances. In addition, these results will foster more studies on a wide range of two-dimensional conjugated polymers with different lattice symmetries, thereby gaining further insights into the structure vs. properties of these systems.

The Italian/Canadian team demonstrated the synthesis of large-scale two-dimensional conjugated polymers, also thoroughly characterizing their electronic properties. They achieved success by combining the complementary expertise of organic chemists and surface scientists.

“This work represents an exciting development in the realization of functional two-dimensional materials beyond graphene,” said Mark Gallagher, a Physics professor at Lakehead University.

“I found it particularly rewarding to participate in this collaboration, which allowed us to combine our expertise in organic chemistry, condensed matter physics, and materials science to achieve our goals.”

Dmytro Perepichka, a professor and chair of Chemistry at McGill University, said they have been working on this research for a long time.

“Structurally reconfigurable two-dimensional conjugated polymers can give a new breadth to applications of two-dimensional materials in electronics,” Perepichka said.

“We started dreaming of them more than 15 years ago. It’s only through this four-way collaboration, across the country and between the continents, that this dream has become the reality.”

Federico Rosei, a professor at the Énergie Matériaux Télécommunications Research Centre of the Institut National de la Recherche Scientifique (INRS) in Varennes who holds the Canada Research Chair in Nanostructured Materials since 2016, said they are excited about the results of this collaboration.

“These results provide new insights into mechanisms of surface reactions at a fundamental level and simultaneously yield a novel material with outstanding properties, whose existence had only been predicted theoretically until now,” he said.

I’m a little surprised there wasn’t a quote from one of the Italian researchers in the McGill news release but then there isn’t a quote in this slightly more accessible May 18, 2020 Consiglio Nazionale delle Ricerche press release either,

Graphene’s isolation took the world by surprise and was meant to revolutionize modern electronics. However, it was soon realized that its intrinsic properties limit the utilization in our daily electronic devices. When a concept of Mathematics, namely Topology, met the field of on-surface chemistry, new materials with exotic features were theoretically discovered. Topological materials exhibit technological relevant properties such as quantum hall conductivity that are protected by a concept similar to the comparison of a coffee mug and a donut.  These structures can be synthesized by the versatile molecular engineering toolbox that surface reactions provide. Nevertheless, the realization of such a material yields access to properties that suit the figure of merits for modern electronic application and could eventually for example lead to solve the ever-increasing heat conflict in chip design. However, problems such as low crystallinity and defect rich structures prevented the experimental observation and kept it for more than a decade a playground only investigated theoretically.

An international team of scientists from Institut National de la Recherche Scientifique (Centre Energie, Matériaux et Télécommunications), McGill University and Lakehead University, both located in Canada, and the SAMOS laboratory of the Istituto di Struttura della Materia (Cnr), led by Giorgio Contini, demonstrates, in a recent publication on Nature Materials, that the synthesis of two-dimensional π-conjugated polymers with topological Dirac cone and flats bands became a reality allowing a sneak peek into the world of organic topological materials.

Complementary work of organic chemists and surface scientists lead to two-dimensional polymers on a mesoscopic scale and granted access to their electronic properties. The band structure of the topological polymer reveals both flat bands and a Dirac cone confirming the prediction of theory. The observed coexistence of both structures is of particular interest, since whereas Dirac cones yield massless charge carriers (a band velocity of the same order of magnitude of graphene has been obtained), necessary for technological applications, flat bands quench the kinetic energy of charge carriers and could give rise to intriguing phenomena such as the anomalous Hall effect, surface superconductivity or superfluid transport.

This work paths multiple new roads – both theoretical and experimental nature. The integration of this topological polymer into a device such as transistors possibly reveals immense performance. On the other hand, it will foster many researchers to explore a wide range of two-dimensional polymers with different lattice symmetries, obtaining insight into the relationship between geometrical and electrical topology, which would in return be beneficial to fine tune a-priori theoretical studies. These materials – beyond graphene – could be then used for both their intrinsic properties as well as their interplay in new heterostructure designs.

The authors are currently exploring the practical use of the realized material trying to integrate it into transistors, pushing toward a complete designing of artificial topological lattices.
