An August 9, 2023 news item on phys.org highlights how superhero anatomy is being employed in human anatomy courses, Note: A link has been removed,

What do superheroes Deadpool and Elastigirl have in common? Each was used in a college anatomy class to add relevance to course discussions—Deadpool to illustrate tissue repair, and Elastigirl, aka Mrs. Incredible, as an example of hyperflexibility.

Instructors at The Ohio State University College of Medicine created a “SuperAnatomy” course in an attempt to improve the experience of undergraduate students learning the notoriously difficult—and for some, scary or gross—subject matter of human anatomy.

An August 9, 2023 Ohio State University news release (also on EurekAlert), which originated the news item, delves further into the topic, Note: Links have been removed,

Surveys showed that most students who took the class found the use of superheroes increased their motivation to learn, fostered deeper understanding of the material, and made the content more approachable and enjoyable.

A few of the many content examples also included considering how Wolverine’s claws would affect his musculoskeletal system and citing Groot in a discussion of skin disorders.The effort was aimed at bringing creativity to the classroom – in the form of outside-the-box instruction and as a way to inspire students’ imagination and keep them engaged, said Melissa Quinn, associate professor of anatomy at Ohio State and senior author of a study on the course’s effectiveness.

“In these introductory courses, it’s a little tougher to talk about clinical relevance because students don’t fully understand a lot of the mechanics,” Quinn said. “But if you bring in pop culture, which everybody is inundated with in some way, shape or form, and tie it to the foundational sciences, then that becomes a way to apply it a little bit more.”

The study was published recently in the journal Anatomical Sciences Education.

First author Jeremy Grachan, the mastermind behind the course’s creation, led design of the curriculum as an Ohio State PhD student and is now an assistant professor of anatomy at Rutgers New Jersey Medical School.

SuperAnatomy was created as a 1000-level three-credit-hour undergraduate course open to students of all majors. The class consisted of three 55-minute lectures each week and lab sessions offered twice in the semester. The course’s curriculum borrowed heavily from Human Anatomy 2300, a four-credit-hour course taken primarily by pre-health profession majors, consisting of live and recorded lectures, review sessions and one lab per week.

Students from both classes were invited to join the study over three semesters in 2021 and 2022; 36 students in SuperAnatomy and 442 students in Human Anatomy participated. Researchers collected data from 50-question quizzes given during the first week of classes and at the end of the semester intended to gauge how well students learned and applied course content. The students also completed pre- and post-course surveys.

The quiz results showed that student learning and application of material in the two courses was essentially the same. And to be clear, the SuperAnatomy content was not all cartoons and comic books.

“We looked at courses already running in our anatomy curriculum and took the relevant parts of those courses and added in the superheroes,” Quinn said. “So we actually elevated the curriculum.”

The follow-up survey of SuperAnatomy participants suggested the inclusion of superheroes strengthened their class experience, with nearly all students reporting that pop culture and superhero references expanded their understanding of course material and boosted their motivation to do well in the class.

“Collectively, if the students are enjoying the course and motivated to learn the material it could be better not only for their academic success, but their mental health and social wellbeing too,” the authors wrote.

Human anatomy is tough stuff – on top of the high volume of unfamiliar medical terms rooted in Latin, it can be unsettling to learn about the body in such a scientific, yet intimate, way.

“If you don’t have a good tour guide to help you, you might be inclined to give up pretty quickly,” Quinn said. “And none of us wants to be stale in our teaching.

“Here, we’ve seen that you can take a course like anatomy, which has been around forever, and bring it very much to whatever generation that we’re going to be teaching. And it’s not just about having fun – but a way to really make anatomy very interesting.”

Mason Marek and James Cray Jr. of Ohio State also co-authored the study.

2023 Nobel prizes (medicine, physics, and chemistry)

For the first time in the 15 years this blog has been around, the Nobel prizes awarded in medicine, physics, and chemistry all are in areas discussed here at one or another. As usual where people are concerned, some of these scientists had a tortuous journey to this prestigious outcome.

Medicine

Two people (Katalin Karikó and Drew Weissman) were awarded the prize in medicine according to the October 2, 2023 Nobel Prize press release, Note: Links have been removed,

The Nobel Assembly at Karolinska Institutet [Sweden]

has today decided to award

the 2023 Nobel Prize in Physiology or Medicine

jointly to

Katalin Karikó and Drew Weissman

for their discoveries concerning nucleoside base modifications that enabled the development of effective mRNA vaccines against COVID-19

The discoveries by the two Nobel Laureates were critical for developing effective mRNA vaccines against COVID-19 during the pandemic that began in early 2020. Through their groundbreaking findings, which have fundamentally changed our understanding of how mRNA interacts with our immune system, the laureates contributed to the unprecedented rate of vaccine development during one of the greatest threats to human health in modern times.

Vaccines before the pandemic

Vaccination stimulates the formation of an immune response to a particular pathogen. This gives the body a head start in the fight against disease in the event of a later exposure. Vaccines based on killed or weakened viruses have long been available, exemplified by the vaccines against polio, measles, and yellow fever. In 1951, Max Theiler was awarded the Nobel Prize in Physiology or Medicine for developing the yellow fever vaccine.

Thanks to the progress in molecular biology in recent decades, vaccines based on individual viral components, rather than whole viruses, have been developed. Parts of the viral genetic code, usually encoding proteins found on the virus surface, are used to make proteins that stimulate the formation of virus-blocking antibodies. Examples are the vaccines against the hepatitis B virus and human papillomavirus. Alternatively, parts of the viral genetic code can be moved to a harmless carrier virus, a “vector.” This method is used in vaccines against the Ebola virus. When vector vaccines are injected, the selected viral protein is produced in our cells, stimulating an immune response against the targeted virus.

Producing whole virus-, protein- and vector-based vaccines requires large-scale cell culture. This resource-intensive process limits the possibilities for rapid vaccine production in response to outbreaks and pandemics. Therefore, researchers have long attempted to develop vaccine technologies independent of cell culture, but this proved challenging.

mRNA vaccines: A promising idea

In our cells, genetic information encoded in DNA is transferred to messenger RNA (mRNA), which is used as a template for protein production. During the 1980s, efficient methods for producing mRNA without cell culture were introduced, called in vitro transcription. This decisive step accelerated the development of molecular biology applications in several fields. Ideas of using mRNA technologies for vaccine and therapeutic purposes also took off, but roadblocks lay ahead. In vitro transcribed mRNA was considered unstable and challenging to deliver, requiring the development of sophisticated carrier lipid systems to encapsulate the mRNA. Moreover, in vitro-produced mRNA gave rise to inflammatory reactions. Enthusiasm for developing the mRNA technology for clinical purposes was, therefore, initially limited.

These obstacles did not discourage the Hungarian biochemist Katalin Karikó, who was devoted to developing methods to use mRNA for therapy. During the early 1990s, when she was an assistant professor at the University of Pennsylvania, she remained true to her vision of realizing mRNA as a therapeutic despite encountering difficulties in convincing research funders of the significance of her project. A new colleague of Karikó at her university was the immunologist Drew Weissman. He was interested in dendritic cells, which have important functions in immune surveillance and the activation of vaccine-induced immune responses. Spurred by new ideas, a fruitful collaboration between the two soon began, focusing on how different RNA types interact with the immune system.

The breakthrough

Karikó and Weissman noticed that dendritic cells recognize in vitro transcribed mRNA as a foreign substance, which leads to their activation and the release of inflammatory signaling molecules. They wondered why the in vitro transcribed mRNA was recognized as foreign while mRNA from mammalian cells did not give rise to the same reaction. Karikó and Weissman realized that some critical properties must distinguish the different types of mRNA.

RNA contains four bases, abbreviated A, U, G, and C, corresponding to A, T, G, and C in DNA, the letters of the genetic code. Karikó and Weissman knew that bases in RNA from mammalian cells are frequently chemically modified, while in vitro transcribed mRNA is not. They wondered if the absence of altered bases in the in vitro transcribed RNA could explain the unwanted inflammatory reaction. To investigate this, they produced different variants of mRNA, each with unique chemical alterations in their bases, which they delivered to dendritic cells. The results were striking: The inflammatory response was almost abolished when base modifications were included in the mRNA. This was a paradigm change in our understanding of how cells recognize and respond to different forms of mRNA. Karikó and Weissman immediately understood that their discovery had profound significance for using mRNA as therapy. These seminal results were published in 2005, fifteen years before the COVID-19 pandemic.

Ill. Mattias Karlén

In further studies published in 2008 and 2010, Karikó and Weissman showed that the delivery of mRNA generated with base modifications markedly increased protein production compared to unmodified mRNA. The effect was due to the reduced activation of an enzyme that regulates protein production. Through their discoveries that base modifications both reduced inflammatory responses and increased protein production, Karikó and Weissman had eliminated critical obstacles on the way to clinical applications of mRNA.

mRNA vaccines realized their potential

Interest in mRNA technology began to pick up, and in 2010, several companies were working on developing the method. Vaccines against Zika virus and MERS-CoV were pursued; the latter is closely related to SARS-CoV-2. After the outbreak of the COVID-19 pandemic, two base-modified mRNA vaccines encoding the SARS-CoV-2 surface protein were developed at record speed. Protective effects of around 95% were reported, and both vaccines were approved as early as December 2020.

The impressive flexibility and speed with which mRNA vaccines can be developed pave the way for using the new platform also for vaccines against other infectious diseases. In the future, the technology may also be used to deliver therapeutic proteins and treat some cancer types.

Several other vaccines against SARS-CoV-2, based on different methodologies, were also rapidly introduced, and together, more than 13 billion COVID-19 vaccine doses have been given globally. The vaccines have saved millions of lives and prevented severe disease in many more, allowing societies to open and return to normal conditions. Through their fundamental discoveries of the importance of base modifications in mRNA, this year’s Nobel laureates critically contributed to this transformative development during one of the biggest health crises of our time.

Scientific background: Discoveries concerning nucleoside base modifications that enabled the development of effective mRNA vaccines against COVID-19

Katalin Karikó was born in 1955 in Szolnok, Hungary. She received her PhD from Szeged’s University in 1982 and performed postdoctoral research at the Hungarian Academy of Sciences in Szeged until 1985. She then conducted postdoctoral research at Temple University, Philadelphia, and the University of Health Science, Bethesda. In 1989, she was appointed Assistant Professor at the University of Pennsylvania, where she remained until 2013. After that, she became vice president and later senior vice president at BioNTech RNA Pharmaceuticals. Since 2021, she has been a Professor at Szeged University and an Adjunct Professor at Perelman School of Medicine at the University of Pennsylvania.

Drew Weissman was born in 1959 in Lexington, Massachusetts, USA. He received his MD, PhD degrees from Boston University in 1987. He did his clinical training at Beth Israel Deaconess Medical Center at Harvard Medical School and postdoctoral research at the National Institutes of Health. In 1997, Weissman established his research group at the Perelman School of Medicine at the University of Pennsylvania. He is the Roberts Family Professor in Vaccine Research and Director of the Penn Institute for RNA Innovations.

The University of Pennsylvania October 2, 2023 news release is a very interesting announcement (more about why it’s interesting afterwards), Note: Links have been removed,

The University of Pennsylvania messenger RNA pioneers whose years of scientific partnership unlocked understanding of how to modify mRNA to make it an effective therapeutic—enabling a platform used to rapidly develop lifesaving vaccines amid the global COVID-19 pandemic—have been named winners of the 2023 Nobel Prize in Physiology or Medicine. They become the 28th and 29th Nobel laureates affiliated with Penn, and join nine previous Nobel laureates with ties to the University of Pennsylvania who have won the Nobel Prize in Medicine.

Nearly three years after the rollout of mRNA vaccines across the world, Katalin Karikó, PhD, an adjunct professor of Neurosurgery in Penn’s Perelman School of Medicine, and Drew Weissman, MD, PhD, the Roberts Family Professor of Vaccine Research in the Perelman School of Medicine, are recipients of the prize announced this morning by the Nobel Assembly in Solna, Sweden.

After a chance meeting in the late 1990s while photocopying research papers, Karikó and Weissman began investigating mRNA as a potential therapeutic. In 2005, they published a key discovery: mRNA could be altered and delivered effectively into the body to activate the body’s protective immune system. The mRNA-based vaccines elicited a robust immune response, including high levels of antibodies that attack a specific infectious disease that has not previously been encountered. Unlike other vaccines, a live or attenuated virus is not injected or required at any point.

When the COVID-19 pandemic struck, the true value of the pair’s lab work was revealed in the most timely of ways, as companies worked to quickly develop and deploy vaccines to protect people from the virus. Both Pfizer/BioNTech and Moderna utilized Karikó and Weissman’s technology to build their highly effective vaccines to protect against severe illness and death from the virus. In the United States alone, mRNA vaccines make up more than 655 million total doses of SARS-CoV-2 vaccines that have been administered since they became available in December 2020.

Editor’s Note: The Pfizer/BioNTech and Moderna COVID-19 mRNA vaccines both use licensed University of Pennsylvania technology. As a result of these licensing relationships, Penn, Karikó and Weissman have received and may continue to receive significant financial benefits in the future based on the sale of these products. BioNTech provides funding for Weissman’s research into the development of additional infectious disease vaccines.

Science can be brutal

Now for the interesting bit: it’s in my March 5, 2021 posting (mRNA, COVID-19 vaccines, treating genetic diseases before birth, and the scientist who started it all),

Before messenger RNA was a multibillion-dollar idea, it was a scientific backwater. And for the Hungarian-born scientist behind a key mRNA discovery, it was a career dead-end.

Katalin Karikó spent the 1990s collecting rejections. Her work, attempting to harness the power of mRNA to fight disease, was too far-fetched for government grants, corporate funding, and even support from her own colleagues.

“Every night I was working: grant, grant, grant,” Karikó remembered, referring to her efforts to obtain funding. “And it came back always no, no, no.”

By 1995, after six years on the faculty at the University of Pennsylvania, Karikó got demoted. [emphasis mine] She had been on the path to full professorship, but with no money coming in to support her work on mRNA, her bosses saw no point in pressing on.

She was back to the lower rungs of the scientific academy.

“Usually, at that point, people just say goodbye and leave because it’s so horrible,” Karikó said.

There’s no opportune time for demotion, but 1995 had already been uncommonly difficult. Karikó had recently endured a cancer scare, and her husband was stuck in Hungary sorting out a visa issue. Now the work to which she’d devoted countless hours was slipping through her fingers.

In time, those better experiments came together. After a decade of trial and error, Karikó and her longtime collaborator at Penn — Drew Weissman [emphasis mine], an immunologist with a medical degree and Ph.D. from Boston University — discovered a remedy for mRNA’s Achilles’ heel.

You can get the whole story from my March 5, 2021 posting, scroll down to the “mRNA—it’s in the details, plus, the loneliness of pioneer researchers, a demotion, and squabbles” subhead. If you are very curious about mRNA and the rough and tumble of the world of science, there’s my August 20, 2021 posting “Getting erased from the mRNA/COVID-19 story” where Ian MacLachlan is featured as a researcher who got erased and where Karikó credits his work.

‘Rowing Mom Wins Nobel’ (credit: rowing website Row 2K)

Karikó’s daughter is a two-time gold medal Olympic athlete as the Canadian Broadcasting Corporation’s (CBC) radio programme, As It Happens, notes in an interview with the daughter (Susan Francia). From an October 4, 2023 As It Happens article (with embedded audio programme excerpt) by Sheena Goodyear,

Olympic gold medallist Susan Francia is coming to terms with the fact that she’s no longer the most famous person in her family.

That’s because the retired U.S. rower’s mother, Katalin Karikó, just won a Nobel Prize in Medicine. The biochemist was awarded alongside her colleague, vaccine researcher Drew Weissman, for their groundbreaking work that led to the development of COVID-19 vaccines. 

“Now I’m like, ‘Shoot! All right, I’ve got to work harder,'” Francia said with a laugh during an interview with As It Happens host Nil Köksal. 

But in all seriousness, Francia says she’s immensely proud of her mother’s accomplishments. In fact, it was Karikó’s fierce dedication to science that inspired Francia to win Olympic gold medals in 2008 and 2012.

“Sport is a lot like science in that, you know, you have a passion for something and you just go and you train, attain your goal, whether it be making this discovery that you truly believe in, or for me, it was trying to be the best in the world,” Francia said.

“It’s a grind and, honestly, I love that grind. And my mother did too.”

… one of her [Karikó] favourite headlines so far comes from a little blurb on the rowing website Row 2K: “Rowing Mom Wins Nobel.”

Nowadays, scientists are trying to harness the power of mRNA to fight cancer, malaria, influenza and rabies. But when Karikó first began her work, it was a fringe concept. For decades, she toiled in relative obscurity, struggling to secure funding for her research.

“That’s also that same passion that I took into my rowing,” Francia said.

But even as Karikó struggled to make a name for herself, she says her own mother, Zsuzsanna, always believed she would earn a Nobel Prize one day.

Every year, as the Nobel Prize announcement approached, she would tell Karikó she’d be watching for her name. 

“I was laughing [and saying] that, ‘Mom, I am not getting anything,'” she said. 

But her mother, who died a few years ago, ultimately proved correct. 

Congratulations to both Katalin Karikó and Drew Weissman and thank you both for persisting!

Physics

This prize is for physics at the attoscale.

Aaron W. Harrison (Assistant Professor of Chemistry, Austin College, Texas, US) attempts an explanation of an attosecond in his October 3, 2023 essay (in English “What is an attosecond? A physical chemist explains the tiny time scale behind Nobel Prize-winning research” and in French “Nobel de physique : qu’est-ce qu’une attoseconde?”) for The Conversation, Note: Links have been removed,

“Atto” is the scientific notation prefix that represents 10-18, which is a decimal point followed by 17 zeroes and a 1. So a flash of light lasting an attosecond, or 0.000000000000000001 of a second, is an extremely short pulse of light.

In fact, there are approximately as many attoseconds in one second as there are seconds in the age of the universe.

Previously, scientists could study the motion of heavier and slower-moving atomic nuclei with femtosecond (10-15) light pulses. One thousand attoseconds are in 1 femtosecond. But researchers couldn’t see movement on the electron scale until they could generate attosecond light pulses – electrons move too fast for scientists to parse exactly what they are up to at the femtosecond level.

Harrison does a very good job of explaining something that requires a leap of imagination. He also explains why scientists engage in attosecond research. h/t October 4, 2023 news item on phys.org

Main event

Here’s the October 3, 2023 Nobel Prize press release, Note: A link has been removed,

The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Physics 2023 to

Pierre Agostini
The Ohio State University, Columbus, USA

Ferenc Krausz
Max Planck Institute of Quantum Optics, Garching and Ludwig-Maximilians-Universität München, Germany

Anne L’Huillier
Lund University, Sweden

“for experimental methods that generate attosecond pulses of light for the study of electron dynamics in matter”

Experiments with light capture the shortest of moments

The three Nobel Laureates in Physics 2023 are being recognised for their experiments, which have given humanity new tools for exploring the world of electrons inside atoms and molecules. Pierre Agostini, Ferenc Krausz and Anne L’Huillier have demonstrated a way to create extremely short pulses of light that can be used to measure the rapid processes in which electrons move or change energy.

Fast-moving events flow into each other when perceived by humans, just like a film that consists of still images is perceived as continual movement. If we want to investigate really brief events, we need special technology. In the world of electrons, changes occur in a few tenths of an attosecond – an attosecond is so short that there are as many in one second as there have been seconds since the birth of the universe.

The laureates’ experiments have produced pulses of light so short that they are measured in attoseconds, thus demonstrating that these pulses can be used to provide images of processes inside atoms and molecules.

In 1987, Anne L’Huillier discovered that many different overtones of light arose when she transmitted infrared laser light through a noble gas. Each overtone is a light wave with a given number of cycles for each cycle in the laser light. They are caused by the laser light interacting with atoms in the gas; it gives some electrons extra energy that is then emitted as light. Anne L’Huillier has continued to explore this phenomenon, laying the ground for subsequent breakthroughs.

In 2001, Pierre Agostini succeeded in producing and investigating a series of consecutive light pulses, in which each pulse lasted just 250 attoseconds. At the same time, Ferenc Krausz was working with another type of experiment, one that made it possible to isolate a single light pulse that lasted 650 attoseconds.

The laureates’ contributions have enabled the investigation of processes that are so rapid they were previously impossible to follow.

“We can now open the door to the world of electrons. Attosecond physics gives us the opportunity to understand mechanisms that are governed by electrons. The next step will be utilising them,” says Eva Olsson, Chair of the Nobel Committee for Physics.

There are potential applications in many different areas. In electronics, for example, it is important to understand and control how electrons behave in a material. Attosecond pulses can also be used to identify different molecules, such as in medical diagnostics.

A Canadian connection?

An October 3, 2023 CBC online news item from the Associated Press reveals a Canadian connection of sorts ,

Three scientists have won the Nobel Prize in physics Tuesday for giving us the first split-second glimpse into the superfast world of spinning electrons, a field that could one day lead to better electronics or disease diagnoses.

The award went to French-Swedish physicist Anne L’Huillier, French scientist Pierre Agostini and Hungarian-born Ferenc Krausz for their work with the tiny part of each atom that races around the centre, and that is fundamental to virtually everything: chemistry, physics, our bodies and our gadgets.

Electrons move around so fast that they have been out of reach of human efforts to isolate them. But by looking at the tiniest fraction of a second possible, scientists now have a “blurry” glimpse of them, and that opens up whole new sciences, experts said.

“The electrons are very fast, and the electrons are really the workforce in everywhere,” Nobel Committee member Mats Larsson said. “Once you can control and understand electrons, you have taken a very big step forward.”

L’Huillier is the fifth woman to receive a Nobel in Physics.

L’Huillier was teaching basic engineering physics to about 100 undergraduates at Lund when she got the call that she had won, but her phone was on silent and she didn’t pick up. She checked it during a break and called the Nobel Committee.

Then she went back to teaching.

Agostini, an emeritus professor at Ohio State University, was in Paris and could not be reached by the Nobel Committee before it announced his win to the world

Here’s the Canadian connection (from the October 3, 2023 CBC online news item),

Krausz, of the Max Planck Institute of Quantum Optics and Ludwig Maximilian University of Munich, told reporters that he was bewildered.

“I have been trying to figure out since 11 a.m. whether I’m in reality or it’s just a long dream,” the 61-year-old said.

Last year, Krausz and L’Huillier won the prestigious Wolf prize in physics for their work, sharing it with University of Ottawa scientist Paul Corkum [emphasis mine]. Nobel prizes are limited to only three winners and Krausz said it was a shame that it could not include Corkum.

Corkum was key to how the split-second laser flashes could be measured [emphasis mine], which was crucial, Krausz said.

Congratulations to Pierre Agostini, Ferenc Krausz and Anne L’Huillier and a bow to Paul Corkum!

For those who are curious. a ‘Paul Corkum’ search should bring up a few postings on this blog but I missed this piece of news, a May 4, 2023 University of Ottawa news release about Corkum and the 2022 Wolf Prize, which he shared with Krausz and L’Huillier,

Chemistry

There was a little drama where this prize was concerned, It was announced too early according to an October 4, 2023 news item on phys.org and, again, in another October 4, 2023 news item on phys.org (from the Oct. 4, 2023 news item by Karl Ritter for the Associated Press),

Oops! Nobel chemistry winners are announced early in a rare slip-up

The most prestigious and secretive prize in science ran headfirst into the digital era Wednesday when Swedish media got an emailed press release revealing the winners of the Nobel Prize in chemistry and the news prematurely went public.

Here’s the fully sanctioned October 4, 2023 Nobel Prize press release, Note: A link has been removed,

The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Chemistry 2023 to

Moungi G. Bawendi

“for the discovery and synthesis of quantum dots”

They planted an important seed for nanotechnology

The Nobel Prize in Chemistry 2023 rewards the discovery and development of quantum dots, nanoparticles so tiny that their size determines their properties. These smallest components of nanotechnology now spread their light from televisions and LED lamps, and can also guide surgeons when they remove tumour tissue, among many other things.

Everyone who studies chemistry learns that an element’s properties are governed by how many electrons it has. However, when matter shrinks to nano-dimensions quantum phenomena arise; these are governed by the size of the matter. The Nobel Laureates in Chemistry 2023 have succeeded in producing particles so small that their properties are determined by quantum phenomena. The particles, which are called quantum dots, are now of great importance in nanotechnology.

“Quantum dots have many fascinating and unusual properties. Importantly, they have different colours depending on their size,” says Johan Åqvist, Chair of the Nobel Committee for Chemistry.

Physicists had long known that in theory size-dependent quantum effects could arise in nanoparticles, but at that time it was almost impossible to sculpt in nanodimensions. Therefore, few people believed that this knowledge would be put to practical use.

However, in the early 1980s, Alexei Ekimov succeeded in creating size-dependent quantum effects in coloured glass. The colour came from nanoparticles of copper chloride and Ekimov demonstrated that the particle size affected the colour of the glass via quantum effects.

A few years later, Louis Brus was the first scientist in the world to prove size-dependent quantum effects in particles floating freely in a fluid.

In 1993, Moungi Bawendi revolutionised the chemical production of quantum dots, resulting in almost perfect particles. This high quality was necessary for them to be utilised in applications.

Quantum dots now illuminate computer monitors and television screens based on QLED technology. They also add nuance to the light of some LED lamps, and biochemists and doctors use them to map biological tissue.

Quantum dots are thus bringing the greatest benefit to humankind. Researchers believe that in the future they could contribute to flexible electronics, tiny sensors, thinner solar cells and encrypted quantum communication – so we have just started exploring the potential of these tiny particles.

Proving yet again that scientists can have a bumpy trip to a Nobel prize, an October 4, 2023 news item on phys.org describes how one of the winners flunked his first undergraduate chemistry test, Note: Links have been removed,

Talk about bouncing back. MIT professor Moungi Bawendi is a co-winner of this year’s Nobel chemistry prize for helping develop “quantum dots”—nanoparticles that are now found in next generation TV screens and help illuminate tumors within the body.

But as an undergraduate, he flunked his very first chemistry exam, recalling that the experience nearly “destroyed” him.

The 62-year-old of Tunisian and French heritage excelled at science throughout high school, without ever having to break a sweat.

But when he arrived at Harvard University as an undergraduate in the late 1970s, he was in for a rude awakening.

You can find more about the winners and quantum dots in an October 4, 2023 news item on Nanowerk and in Dr. Andrew Maynard’s (Professor of Advanced Technology Transitions, Arizona State University) October 4, 2023 essay for The Conversation (h/t October 4, 2023 news item on phys.org), Note: Links have been removed,

This year’s prize recognizes Moungi Bawendi, Louis Brus and Alexei Ekimov for the discovery and development of quantum dots. For many years, these precisely constructed nanometer-sized particles – just a few hundred thousandths the width of a human hair in diameter – were the darlings of nanotechnology pitches and presentations. As a researcher and adviser on nanotechnology [emphasis mine], I’ve [Dr. Andrew Maynard] even used them myself when talking with developers, policymakers, advocacy groups and others about the promise and perils of the technology.

The origins of nanotechnology predate Bawendi, Brus and Ekimov’s work on quantum dots – the physicist Richard Feynman speculated on what could be possible through nanoscale engineering as early as 1959, and engineers like Erik Drexler were speculating about the possibilities of atomically precise manufacturing in the the 1980s. However, this year’s trio of Nobel laureates were part of the earliest wave of modern nanotechnology where researchers began putting breakthroughs in material science to practical use.

Quantum dots brilliantly fluoresce: They absorb one color of light and reemit it nearly instantaneously as another color. A vial of quantum dots, when illuminated with broad spectrum light, shines with a single vivid color. What makes them special, though, is that their color is determined by how large or small they are. Make them small and you get an intense blue. Make them larger, though still nanoscale, and the color shifts to red.

The wavelength of light a quantum dot emits depends on its size. Maysinger, Ji, Hutter, Cooper, CC BY

There’s also an October 4, 2023 overview article by Tekla S. Perry and Margo Anderson for the IEEE Spectrum about the magazine’s almost twenty-five years of reporting on quantum dots

Comments on today’s (September 20, 2023) media briefing for the US National Science Foundation’s (NSF) inaugural Global Centers Competition awards

I almost missed the briefing but the folks at the US National Science Foundation (NSF) kindly allowed me to join the meeting despite being 10 minutes late. Before launching into my comments, here’s what we were discussing,

From a September 20, 2023 NSF media briefing (received via email),

U. S. National Science Foundation Media Briefing on the Inaugural Global Centers Awards  

Please join the U.S. National Science Foundation this Wednesday September 20th from 12:30 – 1:30 p.m. EST for a discussion and Q&A on the inaugural Global Centers Competition awards. Earlier this week, NSF along with partner funding agencies from Australia, Canada, and the United Kingdom — announced awards totaling $76.4 million for the inaugural Global Centers Competition. These international, interdisciplinary collaborative research centers will apply best practices of broadening participation and community engagement to develop use-inspired research on climate change and clean energy. The centers will also create and promote opportunities for students and early-career researchers to gain education and training in world-class research while enhancing diversity, equity, inclusion, and accessibility.

NSF will have a panel of experts on hand to discuss and answer questions about these new Global Centers and how they will sync talent across the globe to generate the discoveries and solutions needed to empower resilient communities everywhere.

What: Panel discussion and Q&A on NSF’s Global Centers

When: 12:30 – 1:30 p.m. EST, Wednesday, September 20th, 2023

Where: This briefing [is over.]

Note: This briefing is only open to members of the media

I’m glad to have learned about this effort and applaud the NSF for its outreach efforts. By comparison, Canadian agencies (I’m looking at you, Natural Sciences and Engineering Council of Canada [NSERC] and Social Science and Humanities Research Council of Canada [SSHRC]) have a lot to learn.

There’s a little more about the Global Centers Competition awards in a September 18, 2023 NSF news release,

Today [September 18, 2023], the U.S. National Science Foundation — along with partner funding agencies from Australia, Canada, and the United Kingdom — announced awards totaling $76.4 million for the inaugural Global Centers Competition. These international, interdisciplinary collaborative research centers will apply best practices of broadening participation and community engagement to develop use-inspired research on climate change and clean energy. The centers will also create and promote opportunities for students and early-career researchers to gain education and training in world-class research while enhancing diversity, equity, inclusion, and accessibility.

“NSF builds capacity and advances its priorities through these centers of research excellence by uniting diverse teams from around the world,” said NSF Director Sethuraman Panchanathan. “Global Centers will sync talent across the globe to generate the discoveries and solutions needed to empower resilient communities everywhere.”

Global Centers are sponsored in part by a multilateral funding activity led by NSF and four partner funding organizations: Australia’s Commonwealth Scientific and Industrial Research Organization (CSIRO), Canada’s Natural Sciences and Engineering Research Council (NSERC) and Social Science and Humanities Research Council (SSHRC), and the United Kingdom’s UK Research and Innovation (UKRI).

Both collectively and independently, the centers will support convergent interdisciplinary research collaborations focused on assessing and mitigating the impacts of climate change on society, people, and communities. Outcomes from Global Centers’ activities will inform and catalyze the development of innovative solutions and technologies to address climate change. Examples include: enhancing awareness of critical information; advancing and advocating for decarbonization efforts; creating climate change adaptation plans tailored to specific localities and groups; using artificial intelligence to study responses of nature to climate change; transboundary water issues; and scaling the production of next-generation technologies aimed at achieving net zero. Several projects include partnerships with tribal groups or historically Black colleges and universities that will broaden participation.

“The National Science Foundation Global Centres initiative provides students and researchers a platform to advance innovative and interdisciplinary research and gain education and training opportunities in world-class research while also enhancing diversity, equity, inclusion and accessibility,” said NSERC President Alejandro Adem. “We at NSERC look forward to seeing the outcomes of the work being done by some of Canada and the world’s best and brightest minds to tackle one of the biggest issues of our time.”

The awards are divided into two tracks. Track 1 are Implementation grants with co-funding from international partners. Track 2 are Design grants meant to provide seed funding to develop the teams and the science for future competitions. Many additional countries are involved in Track 2 and will increase global engagement.

There are seven Track 1 Global Centers that involve research partnerships with Australia, Canada, and the U.K. Each Track 1 Global Center will be implemented by internationally dispersed teams consisting of U.S. and foreign researchers. U.S. researchers will be supported by NSF up to $5 million over four to five years, while foreign researchers will be supported by their respective country’s funding agency (CSIRO, NSERC, SSHRC and UKRI) with a comparable amount of funds.

There are 14 Track 2 Global Centers that are at the community-driven design stage. These centers’ teams involve U.S. researchers in partnerships with foreign researchers from any country. NSF will provide the U.S. researchers up to $250,000 of seed funding over a two-year period. These multidisciplinary, international teams will coordinate the research and education efforts needed to become competitive for Track-1 funding in the future.

“Our combined investment in Global Centers enables exciting researcher and innovation-led international and interdisciplinary collaboration to drive the energy transition,” said UKRI CEO, Dame Ottoline Leyser. “I look forward to seeing the creative solutions developed through these global collaborations.”

Kirsten Rose, Acting Chief Executive of CSIRO, said as Australia’s national science agency, CSIRO is proud to be part of a strong national contribution to solving this critical global challenge. “Partnering with the NSF’s Global Centers means Australia remains at the global forefront of work to build a clean hydrogen industry, build integrated and equitable energy systems, and partnering with regions and industries for a low emissions future.”

For Canadian researchers who are interested, there’s a National Science Foundation Global Centres webpage on the NSERC website, which answers a lot of questions about the programme from a Canadian perspective. The application deadline for both tracks was May 10, 2023 and there’s no information (as of September 20, 2023) about future competitions. Nice to see the social science and humanities included in the form of a funding agency. (I think this might be the one compliment I deliver to a Canadian funding initiative this year. 🙂

For American researchers, there’s the NSF’s Global Centers webpage; for UK researchers, there’s the United Kingdom’s Research and Innovation’s Global Centres in clean energy and climate change webpage; and for Australian researchers, there’s the CSIRO’s National Science Foundation Global Centers webpage. Application deadlines have passed for all of these competitions and there’s no information (as of September 20, 2023) about future competitions.

A few comments

News about local and international affairs (see Seth Borenstein’s September 20, 2023 Associated Press article “UN chief warns of ‘gates of hell’ in climate summit, but carbon polluting nations stay silent”) and one’s own personal experience with climate issues can be discouraging at times so it’s heartening to see these efforts. Kudos to the organizers of the Global Centers programme and I wish all the researchers success.

Given how new these centers are, it’s understandable that the panelists would be a little fuzzy about specific although they’ve clearly considered and are attempting to address issues such as sharing data, trust, and outreach to various stakeholders and communities.

I wish I’d asked about cybersecurity when they were talking about data. Ah well, there was my question about outreach to people over the age of 50 or 55 as so much of their planning was focused on youth. The panelists who responded (Dr. Tanya Berger-Wolf, Dr. Meng Tao, and Dr. Ashish Sharma) did not seem to have done much thinking about seniors/elders/older people.

I believe bird watching (as mentioned by one of the panelists) does tend to attract older people but citizen science or other hobbies/programmes mentioned may or may not be a good source for seniors outreach. Almost all science outreach tilts to youth including citizen science.

With the planet is not doing so well and with the aging populations in Canada, the US, many European countries, China, Japan, and I’m sure many others perhaps some new thinking about ‘inclusivity’ might be in order. One suggestion, start thinking about age groups. In the same way that 20 is not 30, is not 40, so 55 is not 65, is not 75. One more thing, perhaps take into account life experience. Something that gets forgotten is that a lot of the programmes that people take for granted and a lot of the technology people use today was developed in the 1960s (e.g. Internet). That old person? Maybe it’s someone who founded the UN’s Environment Program (I was teaching a nanotechnology course in a seniors programme and asked students about themselves; I was intimidated by her credentials).

In the end, this Global Center initiative is heartening news.

Combat yellow fever mosquito with carbon black nanoparticles?

This April 19, 2022 news item on Nanowerk announces mosquito research from Ohio State University (OSU), Note: A link has been removed,

Before being accidentally introduced to the New World by the 16th century slave trade, the yellow fever mosquito was a species native only to Africa. Highly adaptable, it has since become an invasive species in North America, but researchers at The Ohio State University may have found a way to squash the pesky population in its juvenile stages.

Recently published in the journal Insects (“Larvicidal Activity of Carbon Black against the Yellow Fever Mosquito Aedes aegypti”), a new paper describes how mosquitoes have evolved a natural resistance to some chemical insecticides, and offers an alternative called carbon black, a type of carbon-based nanoparticles, or CNPs [when it’s specifically carbon black nanoparticles, it may sometimes be abbreviated to CBNPs; more about that at the end of this post].

An April 18, 2022 OSU news release (also on EurekAlert), which originated the news item, describes the work in more detail,

Study co-author and an associate professor of entomology at Ohio State, Peter Piermarini described CNPs as “microscopic” materials made out of organic elements. The study used a modified version of carbon black called Emperor 1800, which is often used to coat automobiles black. While CNPs are a relatively new scientific development, they have been considered as new tools to control various insect and pest infestations, he said.

“If we can learn more about how carbon black works and how to use it safely, we could design a commercially available nanoparticle that is highly effective against insecticide-resistant mosquitoes,” Piermarini said.

The yellow fever mosquito, or Aedes aegypti, is a species of mosquito known for spreading not just yellow fever, but also diseases like the Zika virus, dengue fever and chikungunya fever. Adults rarely fly more than a few hundred meters from where they emerge, but their abundance leads to steady transmission of diseases – enough to claim tens of thousands of lives every year and hospitalize hundreds of thousands more people.

Because of this, the mosquito is considered to be one of the deadliest animals on the planet. For this study, the researchers’ goal was to figure out how toxic these nanomaterials could be to mosquito larvae, or the immature form of the insect.

Contrary to popular belief, not all mosquitoes set their sights on turning our blood into their latest meal. Male mosquitoes subsist only on flower nectar; it’s the females that will consume both flower nectar and blood in a bid to provide their eggs with enough protein to grow.

When female mosquitoes are ready to lay their eggs, they return to standing pools of water, like lakes or birdbaths, to release them. After they hatch, these larvae will stay in the water for about a week until they reach adulthood, and take wing.

To test whether Emperor 1800 would be effective in stopping that process, researchers worked with two different strains of the yellow fever mosquito inside the lab, one extremely susceptible to typical chemical insecticides, and the other, extremely resistant to them.

By applying the carbon black nanomaterials to the water during the earliest stages of the mosquito’s life cycle and checking in 48 hours later, they were able to determine that CNPs kill mosquito larvae both quickly and efficiently.

“Given the properties of carbon black, it has the most potential for killing larvae because it can be suspended in water,” Piermarini said. Their findings showed that the material seemed to accumulate on the mosquito larvae’s head, abdomen, and even in its gut, meaning that at some point, the larvae were ingesting smaller particles of carbon black.

“Our hypothesis is that these materials may be physically obstructing their ability to perform basic biological functions. It could be blocking their digestion, or might be interfering with their ability to breathe,” said Piermarini.

However, there was one thing that Piermarini found particularly surprising.

When first suspended in water, carbon black appeared equally toxic to larvae of insecticide-resistant and insecticide-susceptible mosquitoes, but the longer the carbon black was suspended in water before treating them. it became more toxic to the insecticide-resistant larvae.

“When you first apply the CNP solution it has similar toxicity against both strains,” Piermarini said. “But when you let the suspension age for a few weeks, it tends to become more potent against the resistant strain of mosquitoes.”

Although they couldn’t determine the reason behind the time-lapsed deaths, the study concluded that these new nanomaterials could be extremely beneficial to controlling the species when applied as a preventive treatment to mosquito breeding grounds.

But before it can be utilized by the public, Piermarini said, carbon black needs to undergo rigorous testing to ensure it won’t harm humans and the environment as a whole.

Co-authors were Erick Martinez Rodriguez, a visiting scholar currently in the Ohio State Entomology Graduate program, Parker Evans, a previous PhD student in the Ohio State Translational Plant Sciences Graduate program, and Megha Kalsi, a previous postdoctoral researcher in entomology. This research was supported by Ohio State’s College of Food, Agricultural, and Environmental Sciences and Vaylenx LLC.

The paper appears to be open access.

The naming of things

The nomenclature for carbon at the nanoscale is a little confusing to me. As best as I can determine all of the elements have multiple names at the nanoscale but it’s only with carbon that subcategories function as categories themselves. For example, fullerenes (C60s), single-walled carbon nanotubes (SWCNTs), double-walled carbon nanotubes (DWCNTs), and mulit-walled carbon nanotubes (MWCNTs) are subcategories that stand on their own but, sometimes, are referred to as carbon nanoparticles, which is the main category. I checked carbon black nanoparticles online and found a number of instances where it was abbreviated to CBNP and it can also be a CNP since it is found under the carbon nanoparticle category as per this Wikipedia entry.

Council of Canadian Academies (CCA) Appoints Expert Panel on International Science and Technology Partnerships

Now the Council of Canadian Academies (CCA) has announced its expert panel for the “International Science and Technology Partnership Opportunities” project, I offer my usual guess analysis of the connections between the members of the panle.

This project first was mentioned in my March 2, 2022 posting, scroll down to the “Council of Canadian Academies launches four projects” subhead. One comment before launching into the expert panel, the word innovation, which you’ll see in the announcement, is almost always code for commercialization, business and/or entrepreneurship.

A May 9, 2022 CCA news release (received via email) announced the members of expert panel,

CCA Appoints Expert Panel on International Science and Technology Partnerships

May 9, 2022 – Ottawa, ON

Canada has numerous opportunities to pursue beneficial international partnerships focused on science, technology, and innovation (STI), but finite resources to support them. At the request of Global Affairs Canada, the Council of Canadian Academies (CCA) has formed an Expert Panel to examine best practices and identify key elements of a rigorous, data-enabled approach to selecting international STI partnership opportunities. Monica Gattinger, Director of the Institute for Science, Society and Policy at the University of Ottawa, will serve as Chair of the Expert Panel.

“International STI partnerships can be crucial to advancing Canada’s interests, from economic growth to public health, sustainability, and security,” said Dr. Gattinger. “I look forward to leading this important assessment and working with panel members to develop clear, comprehensive and coherent approaches for evaluating partnership opportunities.”

As Chair, Dr. Gattinger will lead a multidisciplinary group with expertise in science diplomacy, global security, economics and trade, international research collaboration, and program evaluation. The Panel will answer the following question:

In a post-COVID world, how can Canadian public, private and academic organizations evaluate and prioritize STI partnership opportunities with foreign countries to achieve key national objectives, using indicators supported by objective data where possible?

“I’m delighted that an expert of Dr. Gattinger’s experience and knowledge has agreed to chair this panel,” said Eric M. Meslin, PhD, FRSC, FCAHS, President and CEO of the CCA. “I look forward to the report’s findings for informing the use of international partnerships in science, technology, and innovation.”

More information can be found here.

Given the discussion of pronouns and identification, I note that the panel of 11 experts includes six names commonly associated with women and five names commonly associated with men, which suggests some of the gender imbalance (male/female) I’ve noticed in the past is not present in the makeup of this panel.

There are three ‘international’ members and all are from the US. Based on past panels, international members tend to be from the US or the UK or, occasionally, from Australia or Europe.

Geographically, we have extraordinarily high representation (Monica Gattinger, David Perry, Meredith Lilly, Paul Dufour, and Karen Croteau) from people who are linked to Ottawa, Ontario, either educated or working at the University of Ottawa or Carleton University. (Thank goodness; it’s not as if the nation’s capital dominates almost every discussion about Canada. Ottawa, represent!)

As usual, there is no Canadian representing the North. This seems a bit odd given the very high international interest in the Arctic regions.

Ottawa connections

Here are some of the links (that I’ve been able to find) to Ottawa,

Monica Gattinger (from her Institute of Governance profile page),

Dr. Gattinger is an award-winning researcher and highly sought-after speaker, adviser and media commentator in the energy and arts/cultural [emphasis mine] policy sectors….

Gattinger is Fellow at the Canadian Global Affairs Institute, … She holds a Ph.D. in public policy from Carleton University. [emphases mine]

You’ll note David Perry is president of the Canadian Global Affairs Institute and Meredith Lilly is currently at Carleton University.

Perry is a professor at the University of Calgary where the Canadian Global Affairs Institute is headquartered (and it has offices in Ottawa). Here’s more from Perry’s institute profile page,

… He received his PhD in political science from Carleton University [emphasis mine] where his dissertation examined the link between defence budgeting and defence procurement. He is an adjunct professor at the Centre for Military and Strategic Studies at the University of Calgary and a research fellow of the Centre for the Study of Security and Development at Dalhousie University. …

Paul Dufour also has an Ottawa connection, from his 2017 CCA profile page,

Paul Dufour is a Fellow and Adjunct Professor at the Institute for Science, Society and Policy in the University of Ottawa [emphasis mine] and science policy Principal with PaulicyWorks in Gatineau, Québec. He is on the Board of Directors of the graduate student led Science Policy Exchange based in Montréal [emphasis mine], and is [a] member of the Investment Committee for Grand Challenges Canada.

The east coast

I think of Toronto, Ottawa, and Montréal as a kind of East Coast triangle.

Interestingly, Jennifer M. Welsh is at McGill University in Montréal where Paul Dufour was educated.

Representing the third point, Toronto, is Peggy Van de Plassche (judging by her accent in her YouTube videos, she’s from France), from her LinkedIn profile page,

I am a financial services and technology expert, corporate director, business advisor, investor, entrepreneur, and public speaker, fluent in French and English.

Prior to starting Roar Growth, I led innovation for CIBC [Canadian Imperial Bank of Commerce], allocated several billions of capital to technology projects on behalf of CGI and BMO [Bank of Montreal], managed a European family office, and started 2 Fintechs.

Education

I didn’t find any connections to the Ottawa or Montréal panel members but I was mildly interested to see that one of the US members Paul Arthur Berkman is from Harvard University. Otherwise, Van de Plassche stands mostly alone.

The last of my geographical comments

David Perry manages to connect Alberta via his adjunct professorship at the University of Calgary, Ottawa (as noted previously) and Nova Scotia via his fellowship at Dalhousie University.

In addition to Montréal and the ever important Québec connection, Jennifer M. Welsh could be said to connect another prairie province while adding a little more international flair to this panel (from her McGill University profile page,

Professor Jennifer M. Welsh is the Canada 150 Research Chair in Global Governance and Security at McGill University (Montreal, Canada). She was previously Professor and Chair in International Relations at the European University Institute (Florence, Italy) [emphasis mine] and Professor in International Relations at the University of Oxford, [emphasis mine] where she co-founded the Oxford Institute for Ethics, Law and Armed Conflict. From 2013-2016, she served as the Special Adviser to the UN Secretary General, Ban Ki-moon, on the Responsibility to Protect.

… She has a BA from the University of Saskatchewan (Canada),[emphasis mine] and a Masters and Doctorate from the University of Oxford (where she studied as a Rhodes Scholar).

Stewart Beck seems to be located in Vancouver, Canada which gives the panel one West Coast connection, here’s more from his LinkedIn profile page,

As a diplomat, a trade commissioner, and a policy expert, I’ve spent the last 40 years as one of the foremost advocates of Canada’s interests in the U.S. and Asia. From 2014 to 2021 (August), I was the President and CEO of the Asia Pacific Foundation of Canada [APF] [emphasis mine], Canada’s leading research institution on Asia. Under my leadership, the organization added stakeholder value through applied research and as a principal convener on Asia topics, a builder of enviable networks of public and private sector stakeholders, and a leader of conversations on crucial regional issues. Before joining APF Canada, I led a distinguished 30+ year career with Canada’s diplomatic corps. With postings in the U.S. and Asia, culminating with an assignment as Canada’s High Commissioner to India (Ambassador) [emphasis mine], I gained the knowledge and experience to be one of Canada’s recognized experts on Asia and innovation policy. Along the way, I also served in many senior foreign policy and trade positions, including as Canada’s most senior trade and investment development official, Consul General to Shanghai [emphasis mine]and Consul General to San Francisco. Today, Asia is vitally critical to Canada’s economic security, both financially and technologically. Applying my understanding and navigating the challenging geopolitical, economic, and trade environment is the value I bring to strategic conversations on the region. An established network of senior private and public sector officials in Canada and Asia complements the experience I’ve gained over the many years living and working in Asia.

He completed undergraduate and graduate degrees at Queen’s University in Ontario and, given his career in diplomacy, I expect there are many Ottawa connections.

David Audretsch and Caroline S. Wagner of Indiana University and Ohio State University, respectively, are a little unusual. Most of the time, US members are from the East Coast or the West Coast not from one of the Midwest states.

One last comment about Paul Arthur Berkman, his profile page on the Harvard University website reveals unexpected polar connections,

Fulbright Arctic Chair [emphasis mine] 2021-2022, United States Department of State and Norwegian Ministry of Foreign Affairs

Paul Arthur Berkman is science diplomat, polar explorer and global thought leader applying international, interdisciplinary and inclusive processes with informed decisionmaking to balance national interests and common interests for the benefit of all on Earth across generations. Paul wintered in Antarctica [emphasis mine] when he was twenty-two, SCUBA diving throughout the year under the ice, and then taught a course on science into policy as a Visiting Professor at the University of California Los Angeles the following year, visiting all seven continents before the age of thirty.

Hidden diversity

While the panel is somewhat Ottawa-centric with a strong bias towards the US and Europe, there are some encouraging signs.

Beck’s experience in Asia and Berkman’s in the polar regions is good to see. Dufour has written the Canada chapter in two (2015 and 2021) UNESCO Science Reports and offers an excellent overview of the Canadian situation within a global context in the 2021 edition (I haven’t had the time to view the 2015 report).

Economist Audretsch and FinTech entrepreneur Van de Plassche, offer academic and practical perspectives for ‘innovation’ while Perry and Welsh both offer badly needed (Canada has been especially poor in this area; see below) security perspectives.

The rest of the panel offers what you’d expect, extensive science policy experience. I hope Gattinger’s experience with arts/cultural policy will enhance this project.

This CCA project comes at a time when Canada is looking at establishing closer links to the European Union’s science programmes as per my May 11, 2022 posting: Canada’s exploratory talks about joining the European Union’s science funding programme (Horizon Europe).

This project also comes at about the same time the Canadian federal government announced in its 2022 federal budget (covered in my April 19, 2022 posting, scroll down about 25% of the way; you’ll recognize the subhead) a new Canadian investment and Innovation Agency.

Notes on security

Canada has stumbled more than once in this area.The current war waged by Russia in Ukraine offers one of the latest examples of how state actors can wage damage not just in the obvious physical sense but also with cyberattacks. The US suffered a notable attack in May 2021 which forced the shutdown of a major gas pipeline (May 9, 2021 NBC news report).

As for Canada, there is a July 9, 2014 Canadian Broadcasting Corporation news report about a cyberattack on the National Research Council (NRC),

A “highly sophisticated Chinese state-sponsored actor” recently managed to hack into the computer systems at Canada’s National Research Council, according to Canada’s chief information officer, Corinne Charette.

For its part, the NRC says in a statement released Tuesday morning that it is now attempting to rebuild its computer infrastructure and this could take as much a year.

The NRC works with private businesses to advance and develop technological innovations through science and research.

This is not the first time the Canadian government has fallen victim to a cyberattack that seems to have originated in China — but it is the first time the Canadian government has unequivocally blamed China for the attack.

In September 2021 an announcement was made about a new security alliance where Canada was not included (from my September 17, 2021 posting),

Wednesday, September 15, 2021 an announcement of a new alliance in the Indo-Pacific region, the Three Eyes (Australia, UK, and US or AUKUS) was made.

Interestingly all three are part of the Five Eyes intelligence alliance comprised of Australia, Canada, New Zealand, UK, and US. Hmmm … Canada and New Zealand both border the Pacific and last I heard, the UK is still in Europe.

I mention other security breaches such as the Cameron Ortis situation and the Winnipeg-based National Microbiology Lab (NML), the only level 4 lab in Canada in the September 17, 2021 posting under the ‘What is public safety?’ subheading.

It seems like there might be some federal movement on the issues assuming funding for “Securing Canada’s Research from Foreign Threats” in the 2022 federal budget actually appears. It’s in my April 19, 2022 posting about 45% of the way down under the subheading Research security.

I wish the panel good luck.

Literature and your brain (the neuroscience of it)

This guy (Angus Fletcher) is a little too much the evangelist for my taste but the ideas supporting the book he has authored and is promoting in this video are in line with a lot of thinking about vision and memory both of which can be described acts of creativity. In this case, Fletcher is applying these ideas to literature, which he describes as an act of co-creation,

A May 3, 2021 news item on phys.org announces the publication of Fletcher’s book,

If you really want to understand literature, don’t start with the words on a page—start with how it affects your brain.

That’s the message from Angus Fletcher, an English professor with degrees in both literature and neuroscience, who outlines in a new book a different way to read and think about stories, from classic literature to pulp fiction to movies and TV shows.

Literature wasn’t invented just as entertainment or a way to deliver messages to readers, said Fletcher, who is a professor at The Ohio State University.

Stories are actually a form of technology. [emphasis mine] They are tools that were designed by our ancestors to alleviate depression, reduce anxiety, kindle creativity, spark courage and meet a variety of other psychological challenges of being human,” Fletcher said.

“And even though we aren’t taught this in literature classes today, we can still find and use these emotional tools in the stories we read today.”

Here’s more about the book and ideas supporting it in a May 3, 2021 Ohio State University (OSU) news release (also on EurekAlert) by Jeff Grabmeier and Aaron Nestor, which originated the news item,

Fletcher explains these concepts in his book Wonderworks: The 25 Most Powerful Inventions in the History of Literature.

For example, in a chapter about fighting loneliness, he discusses how reading The Godfather by Mario Puzo may help. A chapter on feeding creativity talks about the virtues of Alice in Wonderland and Winnie-the-Pooh. Looking for the best way to make your dreams come true? For that, Fletcher proposes the TV show 30 Rock.

Wonderworks doesn’t ignore the classics: The book discusses how reading Shakespeare can help us heal from grief, Virginia Woolf can assist readers in finding peace of mind, and Homer can support those needing courage.

Fletcher said his neuroscience background very much influences the approach to literature he takes in Wonderworks.

“When you read a favorite poem or story, you may feel joy, you feel a sense of empathy or connection. One of the things I do in the book is provide the scientific validation for the things we’ve long felt when we’ve read favorite books or watched movies or TV shows that we loved,” he said.

“From my neuroscience background and studies that I’ve done, I can see how literature’s inventions plug into different regions of our brain, to make us less lonely or help us build up our courage or do a variety of other things to help us. Every story is different and is, in effect, a different tool.”

Fletcher said to truly understand the power of literature requires a different way of approaching stories from what is offered by most traditional literature courses.

The usual method of teaching literature focuses on the words, asking students to look for themes, to consider what the author intended to say and mean.

But that’s not the focus at Project Narrative, an Ohio State program of which Fletcher is a member.

“At Project Narrative, we reverse the process. Instead of looking at the words first, we look first at what is going on in your mind. How does this story make you feel? We look at how people are responding to the characters, the plot, the world that the author created,” Fletcher said.

After examining how the story makes you feel, the second part of the process is to trace that feeling back to some invention of the story, whether it is the plot, a character, the narrator, or the world of the story.

The themes of the story, or what the author means to say, are less important in this approach to literature.

That means when you are looking for a book to stimulate your courage, you don’t have to look for a book that has “courage” in the title or even as one of its themes according to traditional literature analysis, Fletcher said.

“Courage comes from reading a work of literature that makes us feel like we’re participating in something bigger than ourselves. It doesn’t have to mention courage or have courage be one of its themes,” he said. “That’s not relevant.”

For example, you wouldn’t think of reading The Godfather to ward off loneliness. But Fletcher said it can have this effect, partly through its use of a specific operatic technique. In Wonderworks, Fletcher explains how some operas feature a period of dissonant and turbulent music that is eventually resolved by a sweet harmony.

“The clashing and discordant music is upsetting, but then the sweet relief of harmony comes and releases dopamine in our brain, bonding us to the music,” he said.

“Puzo does the same thing in The Godfather, by creating chaos and tension in a chapter and then just partly resolving it at the end, giving us this partial dopamine rush that bonds us to the characters and to the story and makes us feel like they are friends.”

And even though it may not be good to be friends with gangsters in real life, the dopamine rush that we get from befriending the Corleone family can help ward off loneliness, he said.

If you’re reading stories like The Godfather while isolated during the COVID-19 pandemic, it may even help ease the transition back to normal life when the world opens back up.

Neuroscientists have discovered that a part of the brain, called the dorsal raphe nucleus, helps us make friends, Fletcher said. It contains a cluster of dopamine neurons that are primed for short periods of loneliness and stand ready to encourage us to be sociable when we again meet people.

But if our isolation lasts weeks or months, like during the pandemic, that priming fades and our brain hunkers down in isolation – making it harder to re-connect with people.

“So what The Godfather and other stories can do is wake up the dorsal raphe nucleus and make it easier to rejoin society when the pandemic is over,” he explained.

Fletcher said the use of operatic techniques in The Godfather is just one example of how literature can be a form of technology.

And he hopes more people will want to figure out how these technological tools in literature really work in our brains.

“The idea behind the book is to give you a different way of reading, one that unlocks the extraordinary power of literature to heal your brain, give you more joy, more courage, whatever you need in your life.”

You can order “Wonderworks: The 25 Most Powerful Inventions in the History of Literature” from this Simon & Shuster (publisher) webpage,

A brilliant examination of literary inventions through the ages, from ancient Mesopotamia to Elena Ferrante, that shows how writers have created technical breakthroughs—rivaling any scientific inventions—and engineering enhancements to the human heart and mind.

Literature is a technology like any other. And the writers we revere—from Homer, Shakespeare, Austen, and others—each made a unique technical breakthrough that can be viewed as both a narrative and neuroscientific advancement. Literature’s great invention was to address problems we could not solve: not how to start a fire or build a boat, but how to live and love; how to maintain courage in the face of death; how to account for the fact that we exist at all.

Wonderworks reviews the blueprints for twenty-five of the most powerful developments in the history of literature. These inventions can be scientifically shown to alleviate grief, trauma, loneliness, anxiety, numbness, depression, pessimism, and ennui—all while sparking creativity, courage, love, empathy, hope, joy, and positive change. They can be found all throughout literature—from ancient Chinese lyrics to Shakespeare’s plays, poetry to nursery rhymes and fairy tales, and crime novels to slave narratives.

An easy-to-understand exploration of the new literary field of story science, Wonderworks teaches you everything you wish you learned in your English class. Based on author Angus Fletcher’s own research, it is an eye-opening and thought-provoking work that offers us a new understanding of the power of literature.

Smart paint that ‘talks’ to canes for better safety crossing the street

It would be nice if they had some video of people navigating with the help of this ‘smart’ paint. Perhaps one day. Meanwhile, Adele Peters in her March 7, 2018 article for Fast Company provides a vivid description of how a sight-impaired or blind person could navigate more safely and easily,

The crosswalk on a road in front of the Ohio State School for the Blind looks like one that might be found at any intersection. But the white stripes at the edges are made with “smart paint”–and if a student who is visually impaired crosses while using a cane with a new smart tip, the cane will vibrate when it touches the lines.

The paint uses rare-earth nanocrystals that can emit a unique light signature, which a sensor added to the tip of a cane can activate and then read. “If you pulse a laser or LED into these materials, they’ll pulse back at you at a very specific frequency,” says Josh Collins, chief technology officer at Intelligent Materials [sic], the company that manufacturers the oxides that can be added to paint.

While digging down for more information, this February 12, 2018 article by Ben Levine for Government Technology Magazine was unearthed (Note: Links have been removed),

In this installment of the Innovation of the Month series (read last month’s story here), we explore the use of smart technologies to help blind and visually impaired people better navigate the world around them. A team at Ohio State University has been working on a “smart paint” application to do just that.

MetroLab’s Executive Director Ben Levine sat down with John Lannutti, professor of materials science engineering at Ohio State University; Mary Ball-Swartwout, orientation and mobility specialist at the Ohio State School for the Blind; and Josh Collins, chief technology officer at Intelligent Material to learn more.

John Lannutti (OSU): The goal of “smart paint for networked smart cities” is to assist people who are blind and visually impaired by implementing a “smart paint” technology that provides accurate location services. You might think, “Can’t GPS do that?” But, surprisingly, current GPS-based solutions actually cannot tell whether somebody is walking on the sidewalk or down the middle of the street. Meanwhile, modern urban intersections are becoming increasingly complex. That means that finding a crosswalk, aligning to cross and maintaining a consistent crossing direction while in motion can be challenging for people who are visually impaired.

And of course, crosswalks aren’t the only challenge. For example, our current mapping technologies are unable to provide the exact location of a building’s entrance. We have a technology solution to those challenges. Smart paint is created by adding exotic light-converting oxides to standard road paints. The paint is detected using a “smart cane,” a modified white cane that detects the smart paint and enables portal-to-portal guidance. The smart cane can also be used to notify vehicles — including autonomous vehicles — of a user’s presence in a crosswalk.

As part of this project, we have a whole team of educational, city and industrial partners, including:

Educational partners: 

  • Ohio State School for the Blind — testing and implementation of smart paint technology in Columbus involving both students and adults
  • Western Michigan University — implementation of smart paint technology with travelers who are blind and visually impaired to maximize orientation and mobility
  • Mississippi State University — the impacts of smart paint technology on mobility and employment for people who are blind and visually impaired

City partners:  

  • Columbus Smart Cities Initiative — rollout of smart paint within Columbus and the paint’s interaction with the Integrated Data Exchange (IDE), a cloud-based platform that dynamically collects user data to show technological impact
  • The city of Tampa, Fla. — rollout of smart paint at the Lighthouse for the Blind
  • The Hillsborough Area Transit Regional Authority, Hillsborough County, Fla. — integration of smart paint with existing bus lines to enable precise location determination
  • The American Council of the Blind — implementation of smart paint with the annual American Council of the Blind convention
  • MetroLab Network — smart paint implementation in city-university partnerships

Industrial collaborators:  

  • Intelligent Material — manufactures and supplies the unique light-converting oxides that make the paint “smart”
  • Crown Technology — paint manufacturing, product evaluation and technical support
  • SRI International — design and manufacturing of the “smart” white cane hardware

Levine: Can you describe what this project focused on and what motivated you to address this particular challenge?

Lannutti: We have been working with Intelligent Material in integrating light-converting oxides into polymeric matrices for specific applications for several years. Intelligent Material supplies these oxides for highly specialized applications across a variety of industries, and has deep experience in filtering and processing the resulting optical outputs. They were already looking at using this technology for automotive applications when the idea to develop applications for people who are blind was introduced. We were extremely fortunate to have the Ohio State School for the Blind (OSSB) right here in Columbus and even more fortunate to have interested collaborators there who have helped us at every step of the way. They even have a room filled with previous white cane technologies; we used those to better understand what works and what doesn’t, helping refine our own product. At about this same time, the National Science Foundation released a call for Smart and Connected Communities proposals, which gave us both a goal and a “home” for this idea.

Levine: How will the tools developed in this project impact planning and the built environment?

Ball-Swartwout: One of the great things about smart paint is that it can be added to the built environment easily at little extra cost. We expect that once smart paint is widely adopted, most sighted users will not notice much difference as smart paint is not visually different from regular road paint. Some intersections might need to have more paint features that enable smart white cane-guided entry from the sidewalk into the crosswalk. Paint that tells users that they have reached their destination may become visible as horizontal stripes along modern sidewalks. These paints could be either gray or black or even invisible to sighted pedestrians, but would still be detectable by “smart” white canes to tell users that they have arrived at their destination.

Levine: Can you tell us about the new technologies that are associated with this project? Can you talk about the status quo versus your vision for the future?

Collins: Beyond converting ceramics in paint, placing a highly sensitive excitation source and detector package at the tip of a moving white cane is truly novel. Also challenging is powering this package using minimal battery weight to decrease the likelihood of wrist and upper neck fatigue.

The status quo is that the travel of citizens who are blind and visually impaired can be unpredictable. They need better technologies for routine travel and especially for travel to any new destinations. In addition, we anticipate that this technology could assist in the travel of people who have a variety of physical and cognitive impairments.

Our vision for the future of this technology is that it will be widespread and utilized constantly. Outside the U.S., Japan and Europe have integrated relatively expensive technologies into streets and sidewalks, and we see smart paint replacing that very quickly. Because the “pain” of installing smart paint is very small, we believe that grass-roots pressure will enable rapid introduction of this technology.

Levine: What was the most surprising thing you learned during this process?

Lannutti: In my mind, the most surprising thing was discovering that sound was not necessarily the best means of guiding users who are blind. This is a bias on the part of sighted individuals as we are used to beeping and buzzing noises that guide or inform us throughout our day. Pedestrians who are blind, on the other hand, need to constantly listen to aspects of their environment to successfully navigate it. For example, listening to traffic noise is extremely important to them as a means of avoiding danger. People who are blind or visually impaired cannot see but need to hear their environment. So we had to dial back our expectations regarding the utility of sound. Instead, we now focus on vibration along the white cane as a means of alerting the user.

If those interested, Levine’s article is well worth reading in its entirety.

Thankfully they’ve added some information to the website for Intelligent Material (Solutions) since I first viewed it.

There’s a bit more information on the Intelligent Material (Solutions’) YouTube video webpage,

Netting oil spills the nano way

Given current local events (April 8, 2015 oil spill in English Bay of 2700 litres (or more) of fuel in Vancouver, Canada), this news item about a mesh useful for oil cleanups seems quite timely. From an April 15, 2015 news item on ScienceDaily,

The unassuming piece of stainless steel mesh in a lab at The Ohio State University doesn’t look like a very big deal, but it could make a big difference for future environmental cleanups.

Water passes through the mesh but oil doesn’t, thanks to a nearly invisible oil-repelling coating on its surface.

In tests, researchers mixed water with oil and poured the mixture onto the mesh. The water filtered through the mesh to land in a beaker below. The oil collected on top of the mesh, and rolled off easily into a separate beaker when the mesh was tilted.

The mesh coating is among a suite of nature-inspired nanotechnologies under development at Ohio State and described in two papers in the journal Nature Scientific Reports. Potential applications range from cleaning oil spills to tracking oil deposits underground.

An April 15, 2015 Ohio State University news release (also on EurekAlert*) by Pam Frost Gorder, which originated the news item, expands on the theme (unusually I’ve left the links undisturbed),

“If you scale this up, you could potentially catch an oil spill with a net,” said Bharat Bhushan, Ohio Eminent Scholar and Howard D. Winbigler Professor of mechanical engineering at Ohio State.

The work was partly inspired by lotus leaves, whose bumpy surfaces naturally repel water but not oil. To create a coating that did the opposite, Bhushan and postdoctoral researcher Philip Brown chose to cover a bumpy surface with a polymer embedded with molecules of surfactant—the stuff that gives cleaning power to soap and detergent.

They sprayed a fine dusting of silica nanoparticles onto the stainless steel mesh to create a randomly bumpy surface and layered the polymer and surfactant on top.

The silica, surfactant, polymer, and stainless steel are all non-toxic and relatively inexpensive, said Brown. He estimated that a larger mesh net could be created for less than a dollar per square foot.

Because the coating is only a few hundred nanometers (billionths of a meter) thick, it is mostly undetectable. To the touch, the coated mesh doesn’t feel any bumpier than uncoated mesh. The coated mesh is a little less shiny, though, because the coating is only 70 percent transparent.

The researchers chose silica in part because it is an ingredient in glass, and they wanted to explore this technology’s potential for creating smudge-free glass coatings. At 70 percent transparency, the coating could work for certain automotive glass applications, such as mirrors, but not most windows or smartphone surfaces.

“Our goal is to reach a transparency in the 90-percent range,” Bhushan said. “In all our coatings, different combinations of ingredients in the layers yield different properties. The trick is to select the right layers.”

He explains that combinations of layers yield nanoparticles that bind to oil instead of repelling it. Such particles could be used to detect oil underground or aid removal in the case of oil spills.

The shape of the nanostructures plays a role, as well. In another project, research assistant Dave Maharaj is investigating what happens when a surface is made of nanotubes. Rather than silica, he experiments with molybdenum disulfide nanotubes, which mix well with oil. The nanotubes are approximately a thousand times smaller than a human hair.

Maharaj measured the friction on the surface of the nanotubes, and compressed them to test how they would hold up under pressure.

“There are natural defects in the structure of the nanotubes,” he said. “And under high loads, the defects cause the layers of the tubes to peel apart and create a slippery surface, which greatly reduces friction.”

Bhushan envisions that the molybdenum compound’s compatibility with oil, coupled with its ability to reduce friction, would make it a good additive for liquid lubricants. In addition, for micro- and nanoscale devices, commercial oils may be too sticky to allow for their efficient operation. Here, he suspects that the molybdenum nanotubes alone could be used to reduce friction.

This work began more than 10 years ago, when Bhushan began building and patenting nano-structured coatings that mimic the texture of the lotus leaf. From there, he and his team have worked to amplify the effect and tailor it for different situations.

“We’ve studied so many natural surfaces, from leaves to butterfly wings and shark skin, to understand how nature solves certain problems,” Bhushan said. “Now we want to go beyond what nature does, in order to solve new problems.”

“Nature reaches a limit of what it can do,” agreed Brown. “To repel synthetic materials like oils, we need to bring in another level of chemistry that nature doesn’t have access to.”

This work was partly funded by the American Chemical Society Petroleum Research Fund, the National Science Foundation, and Dexerials Corporation (formerly a chemical division of Sony Corp.) in Japan.
