Guinea pigging and a walk down memory lane for Remembrance Day 2024

While this isn’t one of my usual areas of interest, there is a personal element for me (more about that at the end). Some people earn their living as subjects for drug tests; it’s called guinea pigging. (There’s more here in a July 1, 2015 posting; see the first three paragraphs after the information about cross-posting and the circumstances under which I wrote the article.)

Earlier this fall (2024), the Canadian Broadcasting Corporation (CBC) released a documentary, Bodies for Rent, focusing on two guinea piggers. Here’s more from a September 25, 2024 CBC online article about their documentary,

Before a drug becomes available on the market, it must undergo rigorous testing and multiple levels of clinical trials to ensure its functionality and safety. Every year, thousands of people in Canada and the U.S. take part in these trials, and may receive financial compensation for doing so. 

A new documentary highlights how some volunteers are attempting to earn a living by putting their bodies on the line. Bodies for Rent follows two men who spend their days searching for eligible clinical studies, and shows the lengths they’ll go to in order to complete a trial and get paid.  

A way to make a ‘living’

Participating in a trial for a medical drug still under development involves reporting any side effects. It’s a potentially dangerous “job,” but for many volunteers, the rewards outweigh the risks. 

“I think I’ve done more than 40 studies,” says 55-year-old “Franco,” who conceals his real identity with makeup in the documentary. “I was struggling to pay my rent. And I saw an ad at the subway in Toronto, and they said, ‘Would you like to make up to $1,200 over a weekend?'”

“I usually make [$30,000] to 40,000 a year. Before, I was making, like, $18,000 working at a factory.”

Raighne, an artist living in Minneapolis, was raised by a single mother and grew up on welfare. “I’ve done about 20 or 30 drug trials,” he says in the film. “And nothing makes money like clinical studies.”

Trying to get out of debt and manage an unstable business, Raighne sometimes spends days or weeks away from home while participating in a study. “I had a friend describe it as, like, ‘drug jail,'” he says. “Because you’re trapped for a set amount of time. You’re under observation.”

From testing on prisoners to testing on the poor

Before the 1970s, most Phase I clinical trials — which look at a drug’s safety, determine the safe dosage range and see if there are any side effects — were conducted on prisoners. This allowed researchers to control and monitor every aspect of participants’ lives. 

“These studies did the most unimaginably horrible things you can think of to prisoners there,” says Carl Elliott, a University of Minnesota bioethicist featured in Bodies for Rent and the author of The Occasional Human Sacrifice: Medical Experimentation and the Price of Saying No [emphasis mine]. 

“For example, they injected inmates with herpes. They injected them with asbestos. They even tested chemical warfare agents on them.”

Public outcry and new reforms eventually made research in prisons much more difficult. “The question was, ‘Well, who do we do Phase I trials on now?’ We can’t do them on prisoners anymore,” says Elliott. 

“The answer is poor people.”

‘A financial incentive to lie’

When testing in prisons stopped and financial incentives were introduced, students and people impacted by poverty became more common test subjects. However, the promise of money at the completion of a trial has added complications. 

“When I started doing studies, I used to be very honest,” says Franco. “I [would] tell all the side effects that I was going through.” 

But after reporting severe migraines during one study, Franco says he was forced to leave — with less than 20 per cent of the promised payout. He says he was also blocked from doing further studies with that company. 

“I [was] being penalized for being honest. So, after that, I kind of learned my lesson and I decided to tone down the side effects,” he says. 

Once in a study, the risks persist. Franco says that after participating for nearly two months in a study worth around $20,000 to him, he received a call from the clinic saying he had inflammation in his pancreas. The study manager told him he was being removed from the study, and later, the clinic advised him to go to an emergency room immediately. 

“I hope it’s not permanent. If it’s permanent, then I’m gonna be upset,” Franco says to the camera in the documentary. “I was supposed to get around $20,000. If I don’t get the full amount because I am getting side effects, I think that it’s unfair.”

In the end, Franco was paid $9,000. 

The September 25, 2024 CBC online article also includes an embedded video about testing on prisoners. “Bodies for Rent” can be viewed on CBC Gem. (You do have to create an account in order to view the documentary or anything else on CBC Gem.)

A walk down memory lane for Remembrance Day 2024

When my father was in basic training for the Canadian army and preparing to fight in World War II, he participated in some kind of experiment. The details are fuzzy as he didn’t talk about it much but he did insist that some of his medical problems (specifically, the problems he had with his skin) were directly due to his experience as a guinea pig and that he should be compensated by the Canadian government. If memory serves, he felt the army had misled him into participating in the experiment. .

Papa was 15 1/2 when he lied his way into the army. Not too long after, the army realizing its mistake kept him back from the front (in some training camp in the Prairies), which is when he became a medical experiment for a time. On reaching the age of 18 the Canadian army shipped him overseas.

When he finally did try to speak up about his experience as a guinea pig it was the late 1960s and he didn’t pursue the matter for long being of the opinion that no one would pay much attention. He wasn’t wrong.

It wasn’t until details about the infamous Tuskegee Syphilis Study were revealed that there was serious discussion about informed consent (about 1972) in the United States. I don’t know when it became a serious discussion in Canada. Even then, some of the research from the 1970s is stomach churning as I found on stumbling across a study from that period. The researchers were conducting an experiment with a drug they knew was not going to work and that had bad side effects as was noted in the abstract. The testing took place on patients in a hospital ward.

There is still a long ways to go as evidenced by the “Bodies for Rent” documentary and Elliott’s 2024 book “The Occasional Human Sacrifice: Medical Experimentation and the Price of Saying No”. I hope there are changes to how drug testing is done as a consequence of added awareness but it’s a long hard road to change.

For my father on Remembrance Day 2024: you were right; what they did to you was wrong. And still, you went and fought. Thank you.

Better (safer, cheaper) battery invented for wearable tech

A June 5, 2024 news item on phys.org announces new research into ‘aqueous’ wearable batteries,

Researchers have developed a safer, cheaper, better performing and more flexible battery option for wearable devices. A paper describing the “recipe” for their new battery type was published in the journal Nano Research Energy on June 3 [2024].

Fitness trackers. Smart watches. Virtual-reality headsets. Even smart clothing and implants. Wearable smart devices are everywhere these days. But for greater comfort, reliability and longevity, these devices will require greater levels of flexibility and miniaturization of their energy storage mechanisms, which are often frustratingly bulky, heavy and fragile. On top of this, any improvements cannot come at the expense of safety.

As a result, in recent years, a great deal of battery research has focused on the development of “micro” flexible energy storage devices, or MFESDs. A range of different structures and electrochemical foundations have been explored, and among them, aqueous micro batteries offer many distinct advantages.

A June 5, 2024 Tsinghua University press release on EurekAlert, which originated the news item, provides more detail,

Aqueous batteries—those that use a water-based solution as an electrolyte (the medium that allows transport of ions in the battery and thus creating an electric circuit) are nothing new. They have been around since the late 19th century. However, their energy density—or the amount of energy contained in the battery per unit of volume—is too low for use in things like electric vehicles as they would take up too much space. Lithium-ion batteries are far more appropriate for such uses.

At the same time, aqueous batteries are much less flammable, and thus safer, than lithium-ion batteries. They are also much cheaper. As a result of this more robust safety and low cost, aqueous options have increasingly been explored as one of the better options for MFESDs. These are termed aqueous micro batteries, or just AMBs.

“Up till now, sadly, AMBs have not lived up to their potential,” said Ke Niu, a materials scientist with the Guangxi Key Laboratory of Optical and Electronic Materials and Devices at the Guilin University of Technology—one of the lead researchers on the team. “To be able to be used in a wearable device, they need to withstand a certain degree of real-world bending and twisting. But most of those explored so far fail in the face of such stress.”

To overcome this, any fractures or failure points in an AMB would need to be self-healing following such stress. Unfortunately, the self-healing AMBs that have been developed so far have tended to depend on metallic compounds as the carriers of charge in the battery’s electric circuit. This has the undesirable side-effect of strong reaction between the metal’s ions and the materials that the electrodes (the battery’s positive and negative electrical conductors) are made out of. This in turn reduces the battery’s reaction rate (the speed at which the electrochemical reactions at the heart of any battery take place), drastically limiting performance.

“So we started investigating the possibility of non-metallic charge carriers, as these would not suffer from the same difficulties from interaction with the electrodes,” added Junjie Shi, another leading member of the team and a researcher with the School of Physics and Center zfor Nanoscale Characterization & Devices (CNCD) at the Huazhong University of Science and Technology in Wuhan.

The research team alighted upon ammonium ions, derived from abundantly available ammonium salts, as the optimal charge carriers. They are far less corrosive than other options and have a wide electrochemical stability window.

“But ammonium ions are not the only ingredient in the recipe needed to make our batteries self-healing,” said Long Zhang, the third leading member of the research team, also at CNCD.

For that, the team incorporated the ammonium salts into a hydrogel—a polymer material that can absorb and retain a large amount of water without disturbing its structure. This gives hydrogels impressive flexibility—delivering precisely the sort of self-healing character needed. Gelatin is probably the most well-known hydrogel, although the researchers in this case opted for a polyvinyl alcohol hydrogel (PVA) for its great strength and low cost.

To optimize compatibility with the ammonium electrolyte, titanium carbide—a ‘2D’ nanomaterial with only a single layer of atoms—was chosen for the anode (the negative electrode) material for its excellent conductivity. Meanwhile manganese dioxide, already commonly used in dry cell batteries, was woven into a carbon nanotube matrix (again to improve conductivity) for the cathode (the positive electrode).

Testing of the prototype self-healing battery showed it exhibited excellent energy density, power density, cycle life, flexibility, and self-healing even after ten self-healing cycles.

The team now aims to further develop and optimise their prototype in preparation for commercial production.

Dealing with mosquitos: a robot story and an engineered human tissue story

I have two ‘mosquito and disease’ stories, the first concerning dengue fever and the second, malaria.

Dengue fever in Taiwan

A June 8, 2023 news item on phys.org features robotic vehicles, dengue fever, and mosquitoes,

Unmanned ground vehicles can be used to identify and eliminate the breeding sources of mosquitos that carry dengue fever in urban areas, according to a new study published in PLOS Neglected Tropical Diseases by Wei-Liang Liu of the Taiwan National Mosquito-Borne Diseases Control Research Center, and colleagues.

It turns out sewers are a problem according to this June 8, 2023 PLOS (Public Library of Science) news release on EurekAlert, provides more context and detail,

Dengue fever is an infectious disease caused by the dengue virus and spread by several mosquito species in the genus Aedes, which also spread chikungunya, yellow fever and zika. Through the process of urbanization, sewers have become easy breeding grounds for Aedes mosquitos and most current mosquito monitoring programs struggle to monitor and analyze the density of mosquitos in these hidden areas.

In the new control effort, researchers combined a crawling robot, wire-controlled cable car and real-time monitoring system into an unmanned ground vehicle system (UGV) that can take high-resolution, real-time images of areas within sewers. From May to August 2018, the system was deployed in five administrative districts in Kaohsiung city, Taiwan, with covered roadside sewer ditches suspected to be hotspots for mosquitos. Mosquito gravitraps were places above the sewers to monitor effects of the UGV intervention on adult mosquitos in the area.

In 20.7% of inspected sewers, the system found traces of Aedes mosquitos in stages from larvae to adult. In positive sewers, additional prevention control measures were carried out, using either insecticides or high-temperature water jets.  Immediately after these interventions, the gravitrap index (GI)—  a measure of the adult mosquito density nearby— dropped significantly from 0.62 to 0.19.

“The widespread use of UGVs can potentially eliminate some of the breeding sources of vector mosquitoes, thereby reducing the annual prevalence of dengue fever in Kaohsiung city,” the authors say.

Dengue on the rise

Like many diseases, dengue is one where you may not have symptoms (asymptomatic), or they’re relatively mild and can be handled at home, or you may need care in a hospital and, in some cases, it can be fatal.

The World Health Organization (WHO) notes that dengue fever cases have increased exponentially since 2000 (from the March 17, 2023 version of the WHO’s “Dengue and severe dengue” fact sheet),

Global burden

The incidence of dengue has grown dramatically around the world in recent decades, with cases reported to WHO increased from 505 430 cases in 2000 to 5.2 million in 2019. A vast majority of cases are asymptomatic or mild and self-managed, and hence the actual numbers of dengue cases are under-reported. Many cases are also misdiagnosed as other febrile illnesses (1).

One modelling estimate indicates 390 million dengue virus infections per year of which 96 million manifest clinically (2). Another study on the prevalence of dengue estimates that 3.9 billion people are at risk of infection with dengue viruses.

The disease is now endemic in more than 100 countries in the WHO Regions of Africa, the Americas, the Eastern Mediterranean, South-East Asia and the Western Pacific. The Americas, South-East Asia and Western Pacific regions are the most seriously affected, with Asia representing around 70% of the global disease burden.

Dengue is spreading to new areas including Europe, [emphasis mine] and explosive outbreaks are occurring. Local transmission was reported for the first time in France and Croatia in 2010 [emphasis mine] and imported cases were detected in 3 other European countries.

The largest number of dengue cases ever reported globally was in 2019. All regions were affected, and dengue transmission was recorded in Afghanistan for the first time. The American Region reported 3.1 million cases, with more than 25 000 classified as severe. A high number of cases were reported in Bangladesh (101 000), Malaysia (131 000) Philippines (420 000), Vietnam (320 000) in Asia.

Dengue continues to affect Brazil, Colombia, the Cook Islands, Fiji, India, Kenya, Paraguay, Peru, the Philippines, the Reunion Islands and Vietnam as of 2021. 

There’s information from an earlier version of the fact sheet, in my July 2, 2013 posting, highlighting different aspects of the disease, e.g., “About 2.5% of those affected die.”

A July 21, 2023 United Nations press release warns that the danger from mosquitoes spreading dengue fever could increase along with the temperature,

Global warming marked by higher average temperatures, precipitation and longer periods of drought, could prompt a record number of dengue infections worldwide, the World Health Organization (WHO) warned on Friday [July 21, 2023].

Despite the absence of mosquitoes infected with the dengue virus in Canada, the government has a Dengue fever information page. At this point, the concern is likely focused on travelers who’ve contracted the disease from elsewhere. However, I am guessing that researchers are keeping a close eye on Canadian mosquitoes as these situations can change.

Malaria in Florida (US)

The researchers from the University of Central Florida (UCF) couldn’t have known when they began their project to study mosquito bites and disease that Florida would register its first malaria cases in 20 years this summer, from a July 26, 2023 article by Stephanie Colombini for NPR ([US] National Public Radio), Note: Links have been removed,

First local transmission in U.S. in 20 years

Heath [Hannah Heath] is one of eight known people in recent months who have contracted malaria in the U.S., after being bitten by a local mosquito, rather than while traveling abroad. The cases comprise the nation’s first locally transmitted outbreak in 20 years. The last time this occurred was in 2003, when eight people tested positive for malaria in Palm Beach, Fla.

One of the eight cases is in Texas; the rest occurred in the northern part of Sarasota County.

The Florida Department of Health recorded the most recent case in its weekly arbovirus report for July 9-15 [2023].

For the past month, health officials have issued a mosquito-borne illness alert for residents in Sarasota and neighboring Manatee County. Mosquito management teams are working to suppress the population of the type of mosquito that carries malaria, Anopheles.

Sarasota Memorial Hospital has treated five of the county’s seven malaria patients, according to Dr. Manuel Gordillo, director of infection control.

“The cases that are coming in are classic malaria, you know they come in with fever, body aches, headaches, nausea, vomiting, diarrhea,” Gordillo said, explaining that his hospital usually treats just one or two patients a year who acquire malaria while traveling abroad in Central or South America, or Africa.

All the locally acquired cases were of Plasmodium vivax malaria, a strain that typically produces milder symptoms or can even be asymptomatic, according to the Centers for Disease Control and Prevention. But the strain can still cause death, and pregnant people and children are particularly vulnerable.

Malaria does not spread from human-to-human contact; a mosquito carrying the disease has to bite someone to transmit the parasites.

Workers with Sarasota County Mosquito Management Services have been especially busy since May 26 [2023], when the first local case was confirmed.

Like similar departments across Florida, the team is experienced in responding to small outbreaks of mosquito-borne illnesses such as West Nile virus or dengue. They have protocols for addressing travel-related cases of malaria as well, but have ramped up their efforts now that they have confirmation that transmission is occurring locally between mosquitoes and humans.

While organizations like the World Health Organization have cautioned climate change could lead to more global cases and deaths from malaria and other mosquito-borne diseases, experts say it’s too soon to tell if the local transmission seen these past two months has any connection to extreme heat or flooding.

“We don’t have any reason to think that climate change has contributed to these particular cases,” said Ben Beard, deputy director of the CDC’s US Centers for Disease Control and Prevention] division of vector-borne diseases and deputy incident manager for this year’s local malaria response.

“In a more general sense though, milder winters, earlier springs, warmer, longer summers – all of those things sort of translate into mosquitoes coming out earlier, getting their replication cycles sooner, going through those cycles faster and being out longer,” he said. And so we are concerned about the impact of climate change and environmental change in general on what we call vector-borne diseases.”.

Beard co-authored a 2019 report that highlights a significant increase in diseases spread by ticks and mosquitoes in recent decades. Lyme disease and West Nile virus were among the top five most prevalent.

“In the big picture it’s a very significant concern that we have,” he said.

Engineered tissue and bloodthirsty mosquitoes

A June 8, 2023 University of Central Florida (UCF) news release (also on EurekAlert) by Eric Eraso describes the research into engineered human tissue and features a ‘bloodthirsty’ video. First, the video,

Note: A link has been removed,

A UCF research team has engineered tissue with human cells that mosquitoes love to bite and feed upon — with the goal of helping fight deadly diseases transmitted by the biting insects.

A multidisciplinary team led by College of Medicine biomedical researcher Bradley Jay Willenberg with Mollie Jewett (UCF Burnett School of Biomedical Sciences) and Andrew Dickerson (University of Tennessee) lined 3D capillary gel biomaterials with human cells to create engineered tissue and then infused it with blood. Testing showed mosquitoes readily bite and blood feed on the constructs. Scientists hope to use this new platform to study how pathogens that mosquitoes carry impact and infect human cells and tissues. Presently, researchers rely largely upon animal models and cells cultured on flat dishes for such investigations.

Further, the new system holds great promise for blood feeding mosquito species that have proven difficult to rear and maintain as colonies in the laboratory, an important practical application. The Willenberg team’s work was published Friday in the journal Insects.

Mosquitos have often been called the world’s deadliest animal, as vector-borne illnesses, including those from mosquitos cause more than 700,000 deaths worldwide each year. Malaria, dengue, Zika virus and West Nile virus are all transmitted by mosquitos. Even for those who survive these illnesses, many are left suffering from organ failure, seizures and serious neurological impacts.

“Many people get sick with mosquito-borne illnesses every year, including in the United States. The toll of such diseases can be especially devastating for many countries around the world,” Willenberg says.

This worldwide impact of mosquito-borne disease is what drives Willenberg, whose lab employs a unique blend of biomedical engineering, biomaterials, tissue engineering, nanotechnology and vector biology to develop innovative mosquito surveillance, control and research tools. He said he hopes to adapt his new platform for application to other vectors such as ticks, which spread Lyme disease.

“We have demonstrated the initial proof-of-concept with this prototype” he says. “I think there are many potential ways to use this technology.”

Captured on video, Willenberg observed mosquitoes enthusiastically blood feeding from the engineered tissue, much as they would from a human host. This demonstration represents the achievement of a critical milestone for the technology: ensuring the tissue constructs were appetizing to the mosquitoes.

“As one of my mentors shared with me long ago, the goal of physicians and biomedical researchers is to help reduce human suffering,” he says. “So, if we can provide something that helps us learn about mosquitoes, intervene with diseases and, in some way, keep mosquitoes away from people, I think that is a positive.”

Willenberg came up with the engineered tissue idea when he learned the National Institutes of Health (NIH) was looking for new in vitro 3D models that could help study pathogens that mosquitoes and other biting arthropods carry.

“When I read about the NIH seeking these models, it got me thinking that maybe there is a way to get the mosquitoes to bite and blood feed [on the 3D models] directly,” he says. “Then I can bring in the mosquito to do the natural delivery and create a complete vector-host-pathogen interface model to study it all together.”

As this platform is still in its early stages, Willenberg wants to incorporate addition types of cells to move the system closer to human skin. He is also developing collaborations with experts that study pathogens and work with infected vectors, and is working with mosquito control organizations to see how they can use the technology.

“I have a particular vision for this platform, and am going after it. My experience too is that other good ideas and research directions will flourish when it gets into the hands of others,” he says. “At the end of the day, the collective ideas and efforts of the various research communities propel a system like ours to its full potential. So, if we can provide them tools to enable their work, while also moving ours forward at the same time, that is really exciting.”

Willenberg received his Ph.D. in biomedical engineering from the University of Florida and continued there for his postdoctoral training and then in scientist, adjunct scientist and lecturer positions.

That final paragraph in the news release is new to me. I’ve seen them list companies where the researchers have financial interests but this is the first time I’ve seen a news release that offers a statement attempting to cover all the bases including some future possibilities such as: “Team members may also be listed as inventors on patent/patent applications that could result in royalty payments.

It seems pretty clear that there’s increasing concern about mosquito-borne diseases no matter where you live.

Virtual panel discussion: Canadian Strategies for Responsible Neurotechnology Innovation on May 16, 2023

The Canadian Science Policy Centre (CSPC) sent a May 11, 2023 notice (via email) about an upcoming event but first, congratulations (Bravo!) are in order,

The Science Meets Parliament [SMP] Program 2023 is now complete and was a huge success. 43 Delegates from across Canada met with 62 Parliamentarians from across the political spectrum on the Hill on May 1-2, 2023.

The SMP Program is championed by CSPC and Canada’s Chief Science Advisor, Dr. Mona Nemer [through the Office of the Chief Science Advisor {OCSA}].

This Program would not have been possible without the generous support of our sponsors: The Royal Military College of Canada, The Stem Cell Network, and the University of British Columbia.

There are 443 seats in Canada’s Parliament with 338 in the House of Commons and 105 in the Senate and 2023 is the third time the SMP programme has been offered. (It was previously held in 2018 and 2022 according to the SMP program page.)

The Canadian programme is relatively new compared to Australia where they’ve had a Science Meets Parliament programme since 1999 (according to a March 20, 2017 essay by Ken Baldwin, Director of Energy Change Institute at Australian National University for The Conversation). The Scottish have had a Science and the Parliament programme since 2000 (according to this 2022 event notice on the Royal Society of Chemistry’s website).

By comparison to the other two, the Canadian programme is a toddler. (We tend not to recognize walking for the major achievement it is.) So, bravo to the CSPC and OCSA on getting 62 Parliamentarians to make time in their schedules to meet a scientist.

Responsible neurotechnology innovation?

From the Canadian Strategies for Responsible Neurotechnology Innovation event page on the CSPC website,

Advances in neurotechnology are redefining the possibilities of improving neurologic health and mental wellbeing, but related ethical, legal, and societal concerns such as privacy of brain data, manipulation of personal autonomy and agency, and non-medical and dual uses are increasingly pressing concerns [emphasis mine]. In this regard, neurotechnology presents challenges not only to Canada’s federal and provincial health care systems, but to existing laws and regulations that govern responsible innovation. In December 2019, just before the pandemic, the OECD [Organisation for Economic Cooperation and Development] Council adopted a Recommendation on Responsible Innovation in Neurotechnology. It is now urging that member states develop right-fit implementation strategies.

What should these strategies look like for Canada? We will propose and discuss opportunities that balance and leverage different professional and governance approaches towards the goal of achieving responsible innovation for the current state of the art, science, engineering, and policy, and in anticipation of the rapid and vast capabilities expected for neurotechnology in the future by and for this country.

One concern I don’t see mentioned is bankruptcy (in other words, what happens if the company that made your neural implant goes bankrupt?) either in the panel description or in the OECD recommendation. My April 5, 2022 posting “Going blind when your neural implant company flirts with bankruptcy (long read)” explored that topic and while many of the excerpted materials present a US perspective, it’s easy to see how it could also apply in Canada and elsewhere.

For those of us on the West Coast, this session starts at 9 am. Enjoy!

The 2023 Canadian federal budget: science & technology of health, the clean economy, reconciliation, and more (1 of 2)

The Canadian federal government released its 2023 budget on Tuesday, March 28, 2023. There were no flashy science research announcements in the budget. Trudeau and his team like to trumpet science initiatives and grand plans (even if they’re reannouncing something from a previous budget) but like last year—this year—not so much.

Consequently, this posting about the annual federal budget should have been shorter than usual. What happened?

Partly, it’s the military spending (chapter 5 of the budget in part 2 of this 2023 budget post). For those who are unfamiliar with the link between military scientific research and their impact on the general population, there are a number of inventions and innovations directly due to military research, e.g., plastic surgery, television, and the internet. (You can check a November 6, 2018 essay for The Conversation by Robert Kirby, Professor of Clinical Education and Surgery at Keele University, for more about the impact of World War 1 and medical research, “World War I: the birth of plastic surgery and modern anaesthesia.”)

So, there’s a lot to be found by inference. Consequently, I found Chapter 3 to also be unexpectedly rich in science and technology efforts.

Throughout both parts of this 2023 Canadian federal budget post, you will find excerpts from individual chapters of the federal budget followed my commentary directly after. My general commentary is reserved for the end.

Sometimes, I have included an item because it piqued my interest. E.g., Canadian agriculture is dependent on Russian fertilizer!!! News to me and I imagine many others. BTW, this budget aims to wean us from this dependency.

Chapter 2: Investing in Public Health Care and Affordable Dental Care

Here goes: from https://www.budget.canada.ca/2023/report-rapport/toc-tdm-en.html,

2.1 Investing in Public Health Care

Improving Canada’s Readiness for Health Emergencies

Vaccines and other cutting-edge life-science innovations have helped us to take control of the COVID-19 pandemic. To support these efforts, the federal government has committed significant funding towards the revitalization of Canada’s biomanufacturing sector through a Biomanufacturing and Life Sciences Strategy [emphasis mine]. To date, the government has invested more than $1.8 billion in 32 vaccine, therapeutic, and biomanufacturing projects across Canada, alongside $127 million for upgrades to specialized labs at universities across the country. Canada is building a life sciences ecosystem that is attracting major investments from leading global companies, including Moderna, AstraZeneca, and Sanofi.

To build upon the progress of the past three years, the government will explore new ways to be more efficient and effective in the development and production of the vaccines, therapies, and diagnostic tools that would be required for future health emergencies. As a first step, the government will further consult Canadian and international experts on how to best organize our readiness efforts for years to come. …

Gold rush in them thar life sciences

I have covered the rush to capitalize on Canadian life sciences research (with a special emphasis on British Columbia) in various posts including (amongst others): my December 30, 2020 posting “Avo Media, Science Telephone, and a Canadian COVID-19 billionaire scientist,” and my August 23, 2021 posting “Who’s running the life science companies’ public relations campaign in British Columbia (Vancouver, Canada)?” There’s also my August 20, 2021 posting “Getting erased from the mRNA/COVID-19 story,” highlighting how brutal the competition amongst these Canadian researchers can be.

Getting back to the 2023 budget, ‘The Biomanufacturing and Life Sciences Strategy’ mentioned in this latest budget was announced in a July 28, 2021 Innovation, Science and Economic Development Canada news release. You can find the strategy here and an overview of the strategy here. You may want to check out the overview as it features links to,

What We Heard Report: Results of the consultation on biomanufacturing and life sciences capacity in Canada

Ontario’s Strategy: Taking life sciences to the next level

Quebec’s Strategy: 2022–2025 Québec Life Sciences Strategy

Nova Scotia’s Strategy: BioFuture2030 Prince Edward Island’s Strategy:

The Prince Edward Island Bioscience Cluster [emphases mine]

2022 saw one government announcement concerning the strategy, from a March 3, 2022 Innovation, Science and Economic Development Canada news release, Note: Links have been removed,

Protecting the health and safety of Canadians and making sure we have the domestic capacity to respond to future health crises are top priorities of the Government of Canada. With the guidance of Canada’s Biomanufacturing and Life Sciences Strategy, the government is actively supporting the growth of a strong, competitive domestic life sciences sector, with cutting-edge biomanufacturing capabilities.

Today [March 3, 2022], the Honourable François-Philippe Champagne, Minister of Innovation, Science and Industry, announced a $92 million investment in adMare BioInnovations to drive company innovation, scale-up and training activities in Canada’s life sciences sector. This investment will help translate commercially promising health research into innovative new therapies and will see Canadian anchor companies provide the training required and drive the growth of Canada’s life science companies.

The real action took place earlier this month (March 2023) just prior to the budget. Oddly, I can’t find any mention of these initiatives in the budget document. (Confession: I have not given the 2023 budget a close reading although I have been through the whole budget once and viewed individual chapters more closely a few times.)

This March 2, 2023 (?) Tri-agency Institutional Programs Secretariat news release kicked things off, Note 1: I found the date at the bottom of their webpage; Note 2: Links have been removed,

The Government of Canada’s main priority continues to be protecting the health and safety of Canadians. Throughout the pandemic, the quick and decisive actions taken by the government meant that Canada was able to scale up domestic biomanufacturing capacity, which had been in decline for over 40 years. Since then, the government is rebuilding a strong and competitive biomanufacturing and life sciences sector brick by brick. This includes strengthening the foundations of the life sciences ecosystem through the research and talent of Canada’s world-class postsecondary institutions and research hospitals, as well as fostering increased collaboration with innovative companies.

Today [March 2, 2023?], the Honourable François-Philippe Champagne, Minister of Innovation, Science and Industry, and the Honourable Jean-Yves Duclos, Minister of Health, announced an investment of $10 million in support of the creation of five research hubs [emphasis mine]:

  • CBRF PRAIRIE Hub, led by the University of Alberta
  • Canada’s Immuno-Engineering and Biomanufacturing Hub, led by The University of British Columbia
  • Eastern Canada Pandemic Preparedness Hub, led by the Université de Montréal
  • Canadian Pandemic Preparedness Hub, led by the University of Ottawa and McMaster University
  • Canadian Hub for Health Intelligence & Innovation in Infectious Diseases, led by the University of Toronto

This investment, made through Stage 1 of the integrated Canada Biomedical Research Fund (CBRF) and Biosciences Research Infrastructure Fund (BRIF) competition, will bolster research and talent development efforts led by the institutions, working in collaboration with their partners. The hubs combine the strengths of academia, industry and the public and not-for-profit sectors to jointly improve pandemic readiness and the overall health and well-being of Canadians.

The multidisciplinary research hubs will accelerate the research and development of next-generation vaccines and therapeutics and diagnostics, while supporting training and development to expand the pipeline of skilled talent. The hubs will also accelerate the translation of promising research into commercially viable products and processes. This investment helps to strengthen the resilience of Canada’s life sciences sector by supporting leading Canadian research in innovative technologies that keep us safe and boost our economy.

Today’s [March 2, 2023?] announcement also launched Stage 2 of the CBRF-BRIF competition. This is a national competition that includes $570 million in available funding for proposals, aimed at cutting-edge research, talent development and research infrastructure projects associated with the selected research hubs. By strengthening research and talent capacity and leveraging collaborations across the entire biomanufacturing ecosystem, Canada will be better prepared to face future pandemics, in order to protect Canadian’s health and safety. 

Then, the Innovation, Science and Economic Development Canada’s March 9, 2023 news release made this announcement, Note: Links have been removed,

Since March 2020, major achievements have been made to rebuild a vibrant domestic life sciences ecosystem to protect Canadians against future health threats. The growth of the sector is a top priority for the Government of Canada, and with over $1.8 billion committed to 33 projects to boost our domestic biomanufacturing, vaccine and therapeutics capacity, we are strengthening our resiliency for current health emergencies and our readiness for future ones.

The COVID-19 Vaccine Task Force played a critical role in guiding and supporting the Government of Canada’s COVID-19 vaccine response. Today [March 9, 2023], recognizing the importance of science-based decisions, the Honourable François-Philippe Champagne, Minister of Innovation, Science and Industry, and the Honourable Jean-Yves Duclos, Minister of Health, are pleased to announce the creation of the Council of Expert Advisors (CEA). The 14 members of the CEA, who held their first official meeting earlier this week, will advise the Government of Canada on the long-term, sustainable growth of Canada’s biomanufacturing and life sciences sector, and on how to enhance our preparedness and capacity to protect the health and safety of Canadians.

The membership of the CEA comprises leaders with in-depth scientific, industrial, academic and public health expertise. The CEA co-chairs are Joanne Langley, Professor of Pediatrics and of Community Health and Epidemiology at the Dalhousie University Faculty of Medicine, and Division Head of Infectious Diseases at the IWK Health Centre; and Marco Marra, Professor in Medical Genetics at the University of British Columbia (UBC), UBC Canada Research Chair in Genome Science and distinguished scientist at the BC Cancer Foundation.

The CEA’s first meeting focused on the previous steps taken under Canada’s Biomanufacturing and Life Sciences Strategy and on its path forward. The creation of the CEA is an important milestone in the strategy, as it continues to evolve and adapt to new technologies and changing conditions in the marketplace and life sciences ecosystem. The CEA will also inform on investments that enhance capacity across Canada to support end-to-end production of critical vaccines, therapeutics and essential medical countermeasures, and to ensure that Canadians can reap the full economic benefits of the innovations developed, including well-paying jobs.

As I’m from British Columbia, I’m highlighting this University of British Columbia (UBC) March 17, 2023 news release about their involvement, Note: Links have been removed,

Canada’s biotech ecosystem is poised for a major boost with the federal government announcement today that B.C. will be home to Canada’s Immuno-Engineering and Biomanufacturing Hub (CIEBH).

The B.C.-based research and innovation hub, led by UBC, brings together a coalition of provincial, national and international partners to position Canada as a global epicentre for the development and manufacturing of next-generation immune-based therapeutics.

A primary goal of CIEBH is to establish a seamless drug development pipeline that will enable Canada to respond to future pandemics and other health challenges in fewer than 100 days.

This hub will build on the strengths of B.C.’s biotech and life sciences industry, and those of our national and global partners, to make Canada a world leader in the development of lifesaving medicines,” said Dr. Deborah Buszard, interim president and vice-chancellor of UBC. “It’s about creating a healthier future for all Canadians. Together with our outstanding alliance of partners, we will ensure Canada is prepared to respond rapidly to future health challenges with homegrown solutions.”

CIEBH is one of five new research hubs announced by the federal government that will work together to improve pandemic readiness and the overall health and well-being of Canadians. Federal funding of $570 million is available over the next four years to support project proposals associated with these hubs in order to advance Canada’s Biomanufacturing and Life Sciences Strategy.

More than 50 organizations representing the private, public, not-for-profit and academic sectors have come together to form the hub, creating a rich environment that will bolster biomedical innovation in Canada. Among these partners are leading B.C. biotech companies that played a key role in Canada’s COVID-19 pandemic response and are developing cutting-edge treatments for a range of human diseases.

CIEBH, led by UBC, will further align the critical mass of biomedical research strengths concentrated at B.C. academic institutions, including the B.C. Institute of Technology, Simon Fraser University and the University of Victoria, as well as the clinical expertise of B.C. research hospitals and health authorities. With linkages to key partners across Canada, including Dalhousie University, the University of Waterloo, and the Vaccine and Infectious Disease Organization, the hub will create a national network to address gaps in Canada’s drug development pipeline.

In recent decades, B.C. has emerged as a global leader in immuno-engineering, a field that is transforming how society treats disease by harnessing and modulating the immune system.

B.C. academic institutions and prominent Canadian companies like Precision NanoSystems, Acuitas Therapeutics and AbCellera have developed significant expertise in advanced immune-based therapeutics such as lipid nanoparticle- and mRNA-based vaccines, engineered antibodies, cell therapies and treatments for antimicrobial resistant infections. UBC professor Dr. Pieter Cullis, a member of CIEBH’s core scientific team, has been widely recognized for his pioneering work developing the lipid nanoparticle delivery technology that enables mRNA therapeutics such as the highly effective COVID-19 mRNA vaccines.

As noted previously, I’m a little puzzled that the federal government didn’t mention the investment in these hubs in their budget. They usually trumpet these kinds of initiatives.

On a related track, I’m even more puzzled that the province of British Columbia does not have its own life sciences research strategy in light of that sector’s success. Certainly it seems that Ontario, Quebec, Nova Scotia, and Prince Edward are all eager to get a piece of the action. Still, there is a Life Sciences in British Columbia: Sector Profile dated June 2020 and an undated (likely from some time between July 2017 to January 2020 when Bruce Ralston whose name is on the document was the relevant cabinet minister) British Columbia Technology and Innovation Policy Framework.

In case you missed the link earlier, see my August 23, 2021 posting “Who’s running the life science companies’ public relations campaign in British Columbia (Vancouver, Canada)?” which includes additional information about the BC life sciences sector, federal and provincial funding, the City of Vancouver’s involvement, and other related matters.

Chapter 3: A Made-In-Canada Plan: Affordable Energy, Good Jobs, and a Growing Clean Economy

The most science-focused information is in Chapter 3, from https://www.budget.canada.ca/2023/report-rapport/toc-tdm-en.html,

3.2 A Growing, Clean Economy

More than US$100 trillion in private capital is projected to be spent between now and 2050 to build the global clean economy.

Canada is currently competing with the United States, the European Union, and countries around the world for our share of this investment. To secure our share of this global investment, we must capitalize on Canada’s competitive advantages, including our skilled and diverse workforce, and our abundance of critical resources that the world needs.

The federal government has taken significant action over the past seven years to support Canada’s net-zero economic future. To build on this progress and support the growth of Canada’s clean economy, Budget 2023 proposes a range of measures that will encourage businesses to invest in Canada and create good-paying jobs for Canadian workers.

This made-in-Canada plan follows the federal tiered structure to incent the development of Canada’s clean economy and provide additional support for projects that need it. This plan includes:

  • Clear and predictable investment tax credits to provide foundational support for clean technology manufacturing, clean hydrogen, zero-emission technologies, and carbon capture and storage;
  • The deployment of financial instruments through the Canada Growth Fund, such as contracts for difference, to absorb certain risks and encourage private sector investment in low-carbon projects, technologies, businesses, and supply chains; and,
  • Targeted clean technology and sector supports delivered by Innovation, Science and Economic Development Canada to support battery manufacturing and further advance the development, application, and manufacturing of clean technologies.

Canada’s Potential in Critical Minerals

As a global leader in mining, Canada is in a prime position to provide a stable resource base for critical minerals [emphasis mine] that are central to major global industries such as clean technology, auto manufacturing, health care, aerospace, and the digital economy. For nickel and copper alone, the known reserves in Canada are more than 10 million tonnes, with many other potential sources at the exploration stage.

The Buy North American provisions for critical minerals and electric vehicles in the U.S. Inflation Reduction Act will create opportunities for Canada. In particular, U.S. acceleration of clean technology manufacturing will require robust supply chains of critical minerals that Canada has in abundance. However, to fully unleash Canada’s potential in critical minerals, we need to ensure a framework is in place to accelerate private investment.

Budget 2022 committed $3.8 billion for Canada’s Critical Minerals Strategy to provide foundational support to Canada’s mining sector to take advantage of these new opportunities. The Strategy was published in December 2022.

On March 24, 2023, the government launched the Critical Minerals Infrastructure Fund [emphasis mine; I cannot find a government announcement/news release for this fund]—a new fund announced in Budget 2022 that will allocate $1.5 billion towards energy and transportation projects needed to unlock priority mineral deposits. The new fund will complement other clean energy and transportation supports, such as the Canada Infrastructure Bank and the National Trade Corridors Fund, as well as other federal programs that invest in critical minerals projects, such as the Strategic Innovation Fund.

The new Investment Tax Credit for Clean Technology Manufacturing proposed in Budget 2023 will also provide a significant incentive to boost private investment in Canadian critical minerals projects and create new opportunities and middle class jobs in communities across the country.

An Investment Tax Credit for Clean Technology Manufacturing

Supporting Canadian companies in the manufacturing and processing of clean technologies, and in the extraction and processing of critical minerals, will create good middle class jobs for Canadians, ensure our businesses remain competitive in major global industries, and support the supply chains of our allies around the world.

While the Clean Technology Investment Tax Credit, first announced in Budget 2022, will provide support to Canadian companies adopting clean technologies, the Clean Technology Manufacturing Investment Tax Credit will provide support to Canadian companies that are manufacturing or processing clean technologies and their precursors.

  • Budget 2023 proposes a refundable tax credit equal to 30 per cent of the cost of investments in new machinery and equipment used to manufacture or process key clean technologies, and extract, process, or recycle key critical minerals, including:
    • Extraction, processing, or recycling of critical minerals essential for clean technology supply chains, specifically: lithium, cobalt, nickel, graphite, copper, and rare earth elements;
    • Manufacturing of renewable or nuclear energy equipment;
    • Processing or recycling of nuclear fuels and heavy water; [emphases mine]
    • Manufacturing of grid-scale electrical energy storage equipment;
    • Manufacturing of zero-emission vehicles; and,
    • Manufacturing or processing of certain upstream components and materials for the above activities, such as cathode materials and batteries used in electric vehicles.

The investment tax credit is expected to cost $4.5 billion over five years, starting in 2023-24, and an additional $6.6 billion from 2028-29 to 2034-35. The credit would apply to property that is acquired and becomes available for use on or after January 1, 2024, and would no longer be in effect after 2034, subject to a phase-out starting in 2032.

3.4 Reliable Transportation and Resilient Infrastructure

Supporting Resilient Infrastructure Through Innovation

The Smart Cities Challenge [emphasis mine] was launched in 2017 to encourage cities to adopt new and innovative approaches to improve the quality of life for their residents. The first round of the Challenge resulted in $75 million in prizes across four winning applicants: Montreal, Quebec; Guelph, Ontario; communities of Nunavut; and Bridgewater, Nova Scotia.

New and innovative solutions are required to help communities reduce the risks and impacts posed by weather-related events and disasters triggered by climate change. To help address this issue, the government will be launching a new round of the Smart Cities Challenge later this year, which will focus on using connected technologies, data, and innovative approaches to improve climate resiliency.

3.5 Investing in Tomorrow’s Technology

With the best-educated workforce on earth, world-class academic and research institutions, and robust start-up ecosystems across the country, Canada’s economy is fast becoming a global technology leader – building on its strengths in areas like artificial intelligence. Canada is already home to some of the top markets for high-tech careers in North America, including the three fastest growing markets between 2016 and 2021: Vancouver, Toronto, and Quebec City.

However, more can be done to help the Canadian economy reach its full potential. Reversing a longstanding trend of underinvestment in research and development by Canadian business [emphasis mine] is essential our long-term economic growth.

Budget 2023 proposes new measures to encourage business innovation in Canada, as well as new investments in college research and the forestry industry that will help to build a stronger and more innovative Canadian economy.

Attracting High-Tech Investment to Canada

In recent months, Canada has attracted several new digital and high-tech projects that will support our innovative economy, including:

  • Nokia: a $340 million project that will strengthen Canada’s position as a leader in 5G and digital innovation;
  • Xanadu Quantum Technologies: a $178 million project that will support Canada’s leadership in quantum computing;
  • Sanctuary Cognitive Systems Corporation: a $121 million project that will boost Canada’s leadership in the global Artificial Intelligence market; and,
  • EXFO: a $77 million project to create a 5G Centre of Excellence that aims to develop one of the world’s first Artificial Intelligence-based automated network solutions.

Review of the Scientific Research and Experimental Development Tax Incentive Program

The Scientific Research and Experimental Development (SR&ED) tax incentive program continues to be a cornerstone of Canada’s innovation strategy by supporting research and development with the goal of encouraging Canadian businesses of all sizes to invest in innovation that drives economic growth.

In Budget 2022, the federal government announced its intention to review the SR&ED program to ensure it is providing adequate support and improving the development, retention, and commercialization of intellectual property, including the consideration of adopting a patent box regime. [emphasis mine] The Department of Finance will continue to engage with stakeholders on the next steps in the coming months.

Modernizing Canada’s Research Ecosystem

Canada’s research community and world-class researchers solve some of the world’s toughest problems, and Canada’s spending on higher education research and development, as a share of GDP, has exceeded all other G7 countries. 

Since 2016, the federal government has committed more than $16 billion of additional funding to support research and science across Canada. This includes:

  • Nearly $4 billion in Budget 2018 for Canada’s research system, including $2.4 billion for the Canada Foundation for Innovation and the granting councils—the Natural Sciences and Engineering Research Council of Canada, the Social Sciences and Humanities Research Council of Canada and the Canadian Institutes of Health Research; [emphases mine]
  • More than $500 million in Budget 2019 in total additional support to third-party research and science organizations, in addition to the creation of the Strategic Science Fund, which will announce successful recipients later this year;
  • $1.2 billion in Budget 2021 for Pan-Canadian Genomics and Artificial Intelligence Strategies, and a National Quantum Strategy;
  • $1 billion in Budget 2021 to the granting councils and the Canada Foundation for Innovation for life sciences researchers and infrastructure; and,
  • The January 2023 announcement of Canada’s intention to become a full member in the Square Kilometre Array Observatory, which will provide Canadian astronomers with access to its ground-breaking data. The government is providing up to $269.3 million to support this collaboration.

In order to maintain Canada’s research strength—and the knowledge, innovations, and talent it fosters—our systems to support science and research must evolve. The government has been consulting with stakeholders, including through the independent Advisory Panel on the Federal Research Support System, to seek advice from research leaders on how to further strengthen Canada’s research support system.

The government is carefully considering the Advisory Panel’s advice, with more detail to follow in the coming months on further efforts to modernize the system.

Using College Research to Help Businesses Grow

Canada’s colleges, CEGEPs, and polytechnic institutes use their facilities, equipment, and expertise to solve applied research problems every day. Students at these institutions are developing the skills they need to start good careers when they leave school, and by partnering with these institutions, businesses can access the talent and the tools they need to innovate and grow.

  • To help more Canadian businesses access the expertise and research and development facilities they need, Budget 2023 proposes to provide $108.6 million over three years, starting in 2023-24, to expand the College and Community Innovation Program, administered by the Natural Sciences and Engineering Research Council.

Supporting Canadian Leadership in Space

For decades, Canada’s participation in the International Space Station has helped to fuel important scientific advances, and showcased Canada’s ability to create leading-edge space technologies, such as Canadarm2. Canadian space technologies have inspired advances in other fields, such as the NeuroArm, the world’s first robot capable of operating inside an MRI, making previously impossible surgeries possible.

  • Budget 2023 proposes to provide $1.1 billion [emphasis mine] over 14 years, starting in 2023-24, on a cash basis, to the Canadian Space Agency [emphasis mine] to continue Canada’s participation in the International Space Station until 2030.

Looking forward, humanity is returning to the moon [emphasis mine]. Canada intends to join these efforts by contributing a robotic lunar utility vehicle to perform key activities in support of human lunar exploration. Canadian participation in the NASA-led Lunar Gateway station—a space station that will orbit the moon—also presents new opportunities for innovative advances in science and technology. Canada is providing Canadarm3 to the Lunar Gateway, and a Canadian astronaut will join Artemis II, the first crewed mission to the moon since 1972. In Budget 2023, the government is providing further support to assist these missions.

  • Budget 2023 proposes to provide $1.2 billion [emphasis mine] over 13 years, starting in 2024-25, to the Canadian Space Agency to develop and contribute a lunar utility vehicle to assist astronauts on the moon.
  • Budget 2023 proposes to provide $150 million [emphasis mine[ over five years, starting in 2023-24, to the Canadian Space Agency for the next phase of the Lunar Exploration Accelerator Program to support the Canada’s world-class space industry and help accelerate the development of new technologies.
  • Budget 2023 also proposes to provide $76.5 million [emphasis mine] over eight years, starting in 2023-24, on a cash basis, to the Canadian Space Agency in support of Canadian science on the Lunar Gateway station.

Investing in Canada’s Forest Economy

The forestry sector plays an important role in Canada’s natural resource economy [emphasis mine], and is a source of good careers in many rural communities across Canada, including Indigenous communities. As global demand for sustainable forest products grows, continued support for Canada’s forestry sector will help it innovate, grow, and support good middle class jobs for Canadians.

  • Budget 2023 proposes to provide $368.4 million over three years, starting in 2023-24, with $3.1 million in remaining amortization, to Natural Resources Canada to renew and update forest sector support, including for research and development, Indigenous and international leadership, and data. Of this amount, $30.1 million would be sourced from existing departmental resources.

Establishing the Dairy Innovation and Investment Fund

The dairy sector is facing a growing surplus of solids non-fat (SNF) [emphasis mine], a by-product of dairy processing. Limited processing capacity for SNF results in lost opportunities for dairy processors and farmers.

  • Budget 2023 proposes to provide $333 million over ten years, starting in 2023-24, for Agriculture and Agri-Food Canada to support investments in research and development of new products based on SNF, market development for these products, and processing capacity for SNF-based products more broadly.

Supporting Farmers for Diversifying Away from Russian Fertilizers

Russia’s illegal invasion of Ukraine has resulted in higher prices for nitrogen fertilizers, which has had a notable impact on Eastern Canadian farmers who rely heavily on imported fertilizer.

  • Budget 2023 proposes to provide $34.1 million over three years, starting in 2023-24, to Agriculture and Agri-Food Canada’s On-Farm Climate Action Fund to support adoption of nitrogen management practices by Eastern Canadian farmers, that will help optimize the use and reduce the need for fertilizer.

Providing Interest Relief for Agricultural Producers

Farm production costs have increased in Canada and around the world, including as a result Russia’s illegal invasion of Ukraine and global supply chain disruptions. It is important that Canada’s agricultural producers have access to the cash flow they need to cover these costs until they sell their products.

  • Budget 2023 proposes to provide $13 million in 2023-24 to Agriculture and Agri-Food Canada to increase the interest-free limit for loans under the Advance Payments Program from $250,000 to $350,000 for the 2023 program year.

Additionally, the government will consult with provincial and territorial counterparts to explore ways to extend help to small agricultural producers who demonstrate urgent financial need.

Maintaining Livestock Sector Exports with a Foot-and-Mouth Disease Vaccine Bank

Foot-and-Mouth Disease (FMD) is a highly transmissible illness that can affect cattle, pigs, and other cloven-hoofed animals. Recent outbreaks in Asia and Africa have increased the risk of global spread, and a FMD outbreak in Canada would cut off exports for all livestock sectors, with major economic implications. However, the impact of a potential outbreak would be significantly reduced with the early vaccination of livestock. 

  • Budget 2023 proposes to provide $57.5 million over five years, starting in 2023-24, with $5.6 million ongoing, to the Canadian Food Inspection Agency to establish a FMD vaccine bank for Canada, and to develop FMD response plans. The government will seek a cost-sharing arrangement with provinces and territories.

Canadian economic theory (the staples theory), mining, nuclear energy, quantum science, and more

Critical minerals are getting a lot of attention these days. (They were featured in the 2022 budget, see my April 19, 2022 posting, scroll down to the Mining subhead.) This year, US President Joe Biden, in his first visit to Canada as President, singled out critical minerals at the end of his 28 hour state visit (from a March 24, 2023 CBC news online article by Alexander Panetta; Note: Links have been removed),

There was a pot of gold at the end of President Joe Biden’s jaunt to Canada. It’s going to Canada’s mining sector.

The U.S. military will deliver funds this spring to critical minerals projects in both the U.S. and Canada. The goal is to accelerate the development of a critical minerals industry on this continent.

The context is the United States’ intensifying rivalry with China.

The U.S. is desperate to reduce its reliance on its adversary for materials needed to power electric vehicles, electronics and many other products, and has set aside hundreds of millions of dollars under a program called the Defence Production Act.

The Pentagon already has told Canadian companies they would be eligible to apply. It has said the cash would arrive as grants, not loans.

On Friday [March 24, 2023], before Biden left Ottawa, he promised they’ll get some.

The White House and the Prime Minister’s Office announced that companies from both countries will be eligible this spring for money from a $250 million US fund.

Which Canadian companies? The leaders didn’t say. Canadian officials have provided the U.S. with a list of at least 70 projects that could warrant U.S. funding.

“Our nations are blessed with incredible natural resources,” Biden told Canadian parliamentarians during his speech in the House of Commons.

Canada in particular has large quantities of critical minerals [emphasis mine] that are essential for our clean energy future, for the world’s clean energy future.

I don’t believe that Joe Biden has ever heard of the Canadian academic Harold Innis (neither have most Canadians) but Biden is echoing a rather well known theory, in some circles, about Canada’s economy (from the Harold Innis Wikipedia entry),

Harold Adams Innis FRSC (November 5, 1894 – November 9, 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, 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, fish, lumber, wheat, mined metals, 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] [all emphases mine]

The staples theory is referred to informally as “hewers of wood and drawers of water.”

Critical Minerals Infrastructure Fund

I cannot find an announcement for this fund (perhaps it’s a US government fund?) but there is a March 7, 2023 Natural Resources Canada news release, Note: A link has been removed,

Simply put, our future depends on critical minerals. The Government of Canada is committed to investing in this future, which is why the Canadian Critical Minerals Strategy — launched by the Honourable Jonathan Wilkinson, Minister of Natural Resources, in December 2022 — is backed by up to $3.8 billion in federal funding. [emphases mine] Today [March 7, 2023], Minister Wilkinson announced more details on the implementation of this Strategy. Over $344 million in funding is supporting the following five new programs and initiatives:

  • Critical Minerals Technology and Innovation Program – $144.4 million for the research, development, demonstration, commercialization and adoption of new technologies and processes that support sustainable growth in Canadian critical minerals value chains and associated innovation ecosystems. 
  • Critical Minerals Geoscience and Data Initiative – $79.2 million to enhance the quality and availability of data and digital technologies to support geoscience and mapping that will accelerate the efficient and effective development of Canadian critical minerals value chains, including by identifying critical minerals reserves and developing pathways for sustainable mineral development. 
  • Global Partnerships Program – $70 million to strengthen Canada’s global leadership role in enhancing critical minerals supply chain resiliency through international collaborations related to critical minerals. 
  • Northern Regulatory Initiative – $40 million to advance Canada’s northern and territorial critical minerals agenda by supporting regulatory dialogue, regional studies, land-use planning, impact assessments and Indigenous consultation.
  • Renewal of the Critical Minerals Centre of Excellence (CMCE) – $10.6 million so the CMCE can continue the ongoing development and implementation of the Canadian Critical Minerals Strategy.

Commentary from the mining community

Mariaan Webb wrote a March 29,2023 article about the budget and the response from the mining community for miningweekly.com, Note: Links have been removed,

The 2023 Budget, delivered by Finance Minister Chrystia Freeland on Tuesday, bolsters the ability of the Canadian mining sector to deliver for the country, recognising the industry’s central role in enabling the transition to a net-zero economy, says Mining Association of Canada (MAC) president and CEO Pierre Gratton.

“Without mining, there are no electric vehicles, no clean power from wind farms, solar panels or nuclear energy, [emphasis mine] and no transmission lines,” said Gratton.

What kind of nuclear energy?

There are two kinds of nuclear energy: fission and fusion. (Fission is the one where the atom is split and requires minerals. Fusion energy is how stars are formed. Much less polluting than fission energy, at this time it is not a commercially viable option nor is it close to being so.)

As far as I’m aware, fusion energy does not require any mined materials. So, Gratton appears to be referring to fission nuclear energy when he’s talking about the mining sector and critical minerals.

I have an October 28, 2022 posting, which provides an overview of fusion energy and the various projects designed to capitalize on it.

Smart Cities in Canada

I was happy to be updated on the Smart Cities Challenge. When I last wrote about it (a March 20, 2018 posting; scroll down to the “Smart Cities, the rest of the country, and Vancouver” subhead). I notice that the successful applicants are from Montreal, Quebec; Guelph, Ontario; communities of Nunavut; and Bridgewater, Nova Scotia. It’s about time northern communities got some attention. It’s hard not to notice that central Canada (i.e., Ontario and Quebec) again dominates.

I look forward to hearing more about the new, upcoming challenge.

The quantum crew

I first made note of what appears to be a fracture in the Canadian quantum community in a May 4, 2021 posting (scroll down to the National Quantum Strategy subhead) about the 2021 budget. I made note of it again in a July 26, 2022 posting (scroll down to the Canadian quantum scene subhead).

In my excerpts from the 3.5 Investing in Tomorrow’s Technology section of the 2023 budget, Xanadu Quantum Technologies, headquartered in Toronto, Ontario is singled out with three other companies (none of which are in the quantum computing field). Oddly, D-Wave Systems (located in British Columbia), which as far as I’m aware is the star of Canada’s quantum computing sector, has yet to be singled out in any budget I’ve seen yet. (I’m estimating I’ve reviewed about 10 budgets.)

Canadians in space

Shortly after the 2023 budget was presented, Canadian astronaut Jeremy Hansen was revealed as one of four astronauts to go on a mission to orbit the moon. From a Canadian Broadcasting (CBC) April 3, 2023 news online article by Nicole Mortillaro (Note: A link has been removed),

Jeremy Hansen is heading to the moon.

The 47-year old Canadian astronaut was announced today as one of four astronauts — along with Christina Koch, Victor Glover and Reid Wiseman — who will be part of NASA’s [US National Aeronautics and Space Administration] Artemis II mission.

Hansen was one of four active Canadian astronauts that included Jennifer Sidey-Gibbons, Joshua Kutryk and David Saint-Jacques vying for a seat on the Orion spacecraft set to orbit the moon.

Artemis II is the second step in NASA’s mission to return astronauts to the surface of the moon. 

The astronauts won’t be landing, but rather they will orbit for 10 days in the Orion spacecraft, testing key components to prepare for Artemis III that will place humans back on the moon some time in 2025 for the first time since 1972.

Canada gets a seat on Artemis II due to its contributions to Lunar Gateway, a space station that will orbit the moon. But Canada is also building a lunar rover provided by Canadensys Aerospace.

On Monday [April 3, 2023], Hansen noted there are two reasons a Canadian is going to the moon, adding that it “makes me smile when I say that.”

The first, he said, is American leadership, and the decision to curate an international team.

“The second reason is Canada’s can-do attitude,” he said proudly.

In addition to our ‘can-do attitude,” we’re also spending some big money, i.e., the Canadian government has proposed in its 2023 budget some $2.5B to various space and lunar efforts over the next several years.

Chapter 3 odds and sods

First seen in the 2022 budget, the patent box regime makes a second appearance in the 2023 budget where apparently ‘stakeholders will be engaged’ later this year. At least, they’re not rushing into this. (For the original announcement and an explanation of a patent box regime, see my April 19, 2022 budget review; scroll down to the Review of Tax Support to R&D and Intellectual Property subhead.)

I’m happy to see the Dairy Innovation and Investment Fund. I’m particularly happy to see a focus on finding uses for solids non-fat (SNF) by providing “$333 million over ten years, starting in 2023-24, … research and development of new products based on SNF [emphasis mine], market development for these products, and processing capacity for SNF-based products more broadly.”

This investment contrasts with the approach to cellulose nanocrystals (CNC) derived from wood (i.e., the forest economy), where the Canadian government invested heavily in research and even opened a production facility under the auspices of a company, CelluForce. It was a little problematic.

By 2013, the facility had a stockpile of CNC and nowhere to sell it. That’s right, no market for CNC as there had been no product development. (See my May 8, 2012 posting where that lack is mentioned, specifically there’s a quote from Tim Harper in an excerpted Globe and Mail article. My August 17, 2016 posting notes that the stockpile was diminishing. The CelluForce website makes no mention of it now in 2023.)

It’s good to see the government emphasis on research into developing products for SNFs especially after the CelluForce stockpile and in light of US President Joe Biden’s recent enthusiasm over our critical minerals.

Chapter 4: Advancing Reconciliation and Building a Canada That Works for Everyone

Chapter 4: Advancing Reconciliation and Building a Canada That Works for Everyone offers this, from https://www.budget.canada.ca/2023/report-rapport/toc-tdm-en.html,

4.3 Clean Air and Clean Water

Progress on Biodiversity

Montreal recently hosted the Fifteenth Conference of the Parties (COP15) to the United Nations Convention on Biological Diversity, which led to a new Post-2020 Global Biodiversity Framework. During COP15, Canada announced new funding for biodiversity and conservation measures at home and abroad that will support the implementation of the Global Biodiversity Framework, including $800 million to support Indigenous-led conservation within Canada through the innovative Project Finance for Permanence model.

Protecting Our Freshwater

Canada is home to 20 per cent of the world’s freshwater supply. Healthy lakes and rivers are essential to Canadians, communities, and businesses across the country. Recognizing the threat to freshwater caused by climate change and pollution, the federal government is moving forward to establish a new Canada Water Agency and make major investments in a strengthened Freshwater Action Plan.

  • Budget 2023 proposes to provide $650 million over ten years, starting in 2023-24, to support monitoring, assessment, and restoration work in the Great Lakes, Lake Winnipeg, Lake of the Woods, St. Lawrence River, Fraser River, Saint John River, Mackenzie River, and Lake Simcoe. Budget 2023 also proposes to provide $22.6 million over three years, starting in 2023-24, to support better coordination of efforts to protect freshwater across Canada.
  • Budget 2023 also proposes to provide $85.1 million over five years, starting in 2023-24, with $0.4 million in remaining amortization and $21 million ongoing thereafter to support the creation of the Canada Water Agency [emphasis mine], which will be headquartered in Winnipeg. By the end of 2023, the government will introduce legislation that will fully establish the Canada Water Agency as a standalone entity.

Cleaner and Healthier Ports

Canada’s ports are at the heart of our supply chains, delivering goods to Canadians and allowing our businesses to reach global markets. As rising shipping levels enable and create economic growth and good jobs, the federal government is taking action to protect Canada’s coastal ecosystems and communities.

  • Budget 2023 proposes to provide $165.4 million over seven years, starting in 2023-24, to Transport Canada to establish a Green Shipping Corridor Program to reduce the impact of marine shipping on surrounding communities and ecosystems. The program will help spur the launch of the next generation of clean ships, invest in shore power technology, and prioritize low-emission and low-noise vessels at ports.

Water, water everywhere

I wasn’t expecting to find mention of establishing a Canada Water Agency and details are sketchy other than, It will be in Winnipeg, Manitoba and there will be government funding. Fingers crossed that this agency will do some good work (whatever that might be). Personally, I’d like to see some action with regard to droughts.

In British Columbia (BC) where I live and which most of us think of as ‘water rich’, is suffering under conditions such that our rivers and lakes are at very low levels according to an April 6, 2023 article by Glenda Luymes for the Vancouver Sun (print version, p. A4),

On the North American WaterWatch map, which codes river flows using a series of coloured dots, high flows are represented in various shades of blue while low flows are represented in red hues. On Wednesday [April 5, 2023], most of BC was speckled red, brown and orange, with the majority of the province’s rivers flowing “much below normal.”

“It does not bode well for the fish populations,” said Marvin Rosenau, a fisheries and ecosystems instructor at BCIT [British Columbia Institute of Technology]. …

Rosenau said low water last fall [2022], when much of BC was in the grip of drought, decreased salmon habitat during spawning season. …

BC has already seen small early season wildfires, including one near Merritt last weekend [April 1/2, 2023]. …

Getting back to the Canada Water Agency, there’s this March 29, 2023 CBC news online article by Bartley Kives,

The 2023 federal budget calls for a new national water agency to be based in Winnipeg, provided Justin Trudeau’s Liberal government remains in power long enough to see it established [emphasis mine] in the Manitoba capital.

The budget announced on Tuesday [March 28, 2023] calls for the creation of the Canada Water Agency, a new federal entity with a headquarters in Winnipeg.

While the federal government is still determining precisely what the new agency will do, one Winnipeg-based environmental organization expects it to become a one-stop shop for water science, water quality assessment and water management [emphasis mine].

“This is something that we don’t actually have in this country at the moment,” said Matt McCandless, a vice-president for the non-profit International Institute for Sustainable Development.

Right now, municipalities, provinces and Indigenous authorities take different approaches to managing water quality, water science, flooding and droughts, said McCandless, adding a national water agency could provide more co-ordination.

For now, it’s unknown how many employees will be based at the Canada Water Agency’s Winnipeg headquarters. According to the budget, legislation to create the agency won’t be introduced until later this year [emphasis mine].

That means the Winnipeg headquarters likely won’t materialize before 2024, one year before the Trudeau minority government faces re-election, assuming it doesn’t lose the confidence of the House of Commons beforehand [emphasis mine].

Nonetheless, several Canadian cities and provinces were vying for the Canada Water Agency’s headquarters, including Manitoba.

The budget also calls for $65 million worth of annual spending on lake science and restoration, with an unstated fraction of that cash devoted to Lake Winnipeg.

McCandless calls the spending on water science an improvement over previous budgets.

Kives seems a tad jaundiced but you get that way (confession: I have too) when covering government spending promises.

Part 2 (military spending and general comments) will be posted sometime during the week of April 24-28, 2023.

Skin-like computing device analyzes health data with brain-mimicking artificial intelligence (a neuromorphic chip)

The wearable neuromorphic chip, made of stretchy semiconductors, can implement artificial intelligence (AI) to process massive amounts of health information in real time. Above, Asst. Prof. Sihong Wang shows a single neuromorphic device with three electrodes. (Photo by John Zich)

Does everything have to be ‘brainy’? Read on for the latest on ‘brainy’ devices.

An August 4, 2022 University of Chicago news release (also on EurekAlert) describes work on a stretchable neuromorphic chip, Note: Links have been removed,

It’s a brainy Band-Aid, a smart watch without the watch, and a leap forward for wearable health technologies. Researchers at the University of Chicago’s Pritzker School of Molecular Engineering (PME) have developed a flexible, stretchable computing chip that processes information by mimicking the human brain. The device, described in the journal Matter, aims to change the way health data is processed.

“With this work we’ve bridged wearable technology with artificial intelligence and machine learning to create a powerful device which can analyze health data right on our own bodies,” said Sihong Wang, a materials scientist and Assistant Professor of Molecular Engineering.

Today, getting an in-depth profile about your health requires a visit to a hospital or clinic. In the future, Wang said, people’s health could be tracked continuously by wearable electronics that can detect disease even before symptoms appear. Unobtrusive, wearable computing devices are one step toward making this vision a reality. 

A Data Deluge
The future of healthcare that Wang—and many others—envision includes wearable biosensors to track complex indicators of health including levels of oxygen, sugar, metabolites and immune molecules in people’s blood. One of the keys to making these sensors feasible is their ability to conform to the skin. As such skin-like wearable biosensors emerge and begin collecting more and more information in real-time, the analysis becomes exponentially more complex. A single piece of data must be put into the broader perspective of a patient’s history and other health parameters.

Today’s smart phones are not capable of the kind of complex analysis required to learn a patient’s baseline health measurements and pick out important signals of disease. However, cutting-edge artificial intelligence platforms that integrate machine learning to identify patterns in extremely complex datasets can do a better job. But sending information from a device to a centralized AI location is not ideal.

“Sending health data wirelessly is slow and presents a number of privacy concerns,” he said. “It is also incredibly energy inefficient; the more data we start collecting, the more energy these transmissions will start using.”

Skin and Brains
Wang’s team set out to design a chip that could collect data from multiple biosensors and draw conclusions about a person’s health using cutting-edge machine learning approaches. Importantly, they wanted it to be wearable on the body and integrate seamlessly with skin.

“With a smart watch, there’s always a gap,” said Wang. “We wanted something that can achieve very intimate contact and accommodate the movement of skin.”

Wang and his colleagues turned to polymers, which can be used to build semiconductors and electrochemical transistors but also have the ability to stretch and bend. They assembled polymers into a device that allowed the artificial-intelligence-based analysis of health data. Rather than work like a typical computer, the chip— called a neuromorphic computing chip—functions more like a human brain, able to both store and analyze data in an integrated way.

Testing the Technology
To test the utility of their new device, Wang’s group used it to analyze electrocardiogram (ECG) data representing the electrical activity of the human heart. They trained the device to classify ECGs into five categories—healthy or four types of abnormal signals. Then, they tested it on new ECGs. Whether or not the chip was stretched or bent, they showed, it could accurately classify the heartbeats.

More work is needed to test the power of the device in deducing patterns of health and disease. But eventually, it could be used either to send patients or clinicians alerts, or to automatically tweak medications.

“If you can get real-time information on blood pressure, for instance, this device could very intelligently make decisions about when to adjust the patient’s blood pressure medication levels,” said Wang. That kind of automatic feedback loop is already used by some implantable insulin pumps, he added.

He already is planning new iterations of the device to both expand the type of devices with which it can integrate and the types of machine learning algorithms it uses.

“Integration of artificial intelligence with wearable electronics is becoming a very active landscape,” said Wang. “This is not finished research, it’s just a starting point.”

Extending a wig’s life with a nanocomposite

A June 13, 2022 American Chemical Society (ACS) news release (also on EurekAlert) announces a nanocomposite that could make wigs last longer,

For some people, wigs are a fun and colorful fashion accessory, but for those with hair loss from alopecia or other conditions, they can provide a real sense of normalcy and boost self-confidence. Whether made from human or synthetic strands, however, most hairpieces lose their luster after being worn day after day. Now, researchers in ACS Applied Materials & Interfaces report a new way to make wigs more durable and long lasting.

Wigs come in all colors of the rainbow and in every style imaginable. Some cover the whole head, while others are “extensions,” sections of hair that clip onto existing locks to make them look fuller or longer. Hairpieces can be made of real human strands or synthetic materials, but either way, washing, UV exposure from the sun and repeated styling can cause these products to become dry and brittle. To extend the wearable life of wigs, some researchers have spray-coated a layer of graphene oxide on them, whereas other teams have immersed wig hairs in a keratin/halloysite nanocomposite. Because it’s difficult to cover an entire hairpiece with these methods, Guang Yang, Huali Nie and colleagues wanted to see if a nanocomposite applied with a tried-and-true approach for coating surfaces with ultrathin films — known as the Langmuir-Blodgett (LB) technique — could improve coverage and increase durability.

The researchers first developed a keratin and graphene oxide nanocomposite as the coating material. To coat hairs with the LB method, they dipped a few human or synthetic hairs into water in a special apparatus with moveable side barriers. After the nanocomposite was spread on the water’s surface with an atomizer, the barriers were moved inward to compress the film— like the trash compactor that almost crushed the heroes in the movie Star Wars. After 30 minutes, the researchers lifted the hairs out of the water, and as they did so, the film coated the locks.

Compared to the immersion technique, the LB method provided more coverage. In addition, hairs treated with the LB approach sustained less UV damage, were less prone to breakage and could hold more moisture than those that were simply immersed in the nanocomposite. They also dissipated heat better and generated less static electricity when rubbed with a rubber sheet. The researchers say that the method can be scaled up for use by companies that manufacture wigs.
