7th annual Vancouver Nanomedicine Day, Sept. 17, 2020

Like so many events these days (COVID-19 days), this event put on by Canada’s NanoMedicines Innovation Network (NMIN) will be held virtually. Here’s more from the ‘Virtual’ Vancouver Nanomedicine Day 2020 event page on the NMIN website,

This world-class symposium, the sixth event of its kind, will bring together a record number (1000+) of renowned Canadian and international experts from across the nanomedicines field to:

  • highlight the discoveries and innovations in nanomedicines that are contributing to global progress in acute, chronic and orphan disease treatment and management;
  • present up-to-date diagnostic and therapeutic  nanomedicine approaches to addressing the challenges of COVID-19; and
  • facilitate discussion among nanomedicine researchers and innovators and UBC and NMIN clinician-scientists, basic researchers, trainees, and research partners.

Since 2014, Vancouver Nanomedicine Day has advanced nanomedicine research, knowledge mobilization and commercialization in Canada by sharing high-impact findings and facilitating interaction—among researchers, postdoctoral fellows, graduate students, and life science and startup biotechnology companies—to catalyze research collaboration.

Here are a few highlights from the ‘Virtual’ Vancouver Nanomedicine Day 2020 event page,

  • An introduction to nanomedicines by Dr. Emmanuel Ho (University of Waterloo)
  • A keynote address by an iconic nanomedicine innovator: Dr. Robert Langer (MIT, Department of Chemical Engineering)
  • Invited talks by internationally renowned experts, including Dr. Vito Foderà (The University of Copenhagen, Denmark); Dr. Lucia Gemma Delogu (University of Padova, Italy); and Dr. Christine Allen (University of Toronto)
  • A virtual poster competition, with cash prizes for the top posters
  • A debate on whether “nanomedicines are still the next big thing” between Marcel Bally (proponent) and Kishor Wasan (opponent)

I have a few observations, First, Robert Langer is a big deal. Here are a few highlights from his Wikipedia entry (Note: Links have been removed),

Robert Samuel Langer, Jr. FREng[2] (born August 29, 1948) is an American chemical engineer, scientist, entrepreneur, inventor and one of the twelve Institute Professors at the Massachusetts Institute of Technology.[3]

Langer holds over 1,350 granted or pending patents.[3][29] He is one of the world’s most highly cited researchers, having authored nearly 1,500 scientific papers, and has participated in the founding of multiple technology companies.[30][31]

Langer is the youngest person in history (at 43) to be elected to all three American science academies: the National Academy of Sciences, the National Academy of Engineering and the Institute of Medicine. He was also elected as a charter member of National Academy of Inventors.[32] He was elected as an International Fellow[2] of the Royal Academy of Engineering[2] in 2010.

It’s all about commercializing the research—or is it?

(This second observation is a little more complicated and requires a little context.) The NMIN is one of Canada’s Networks of Centres of Excellence (who thought that name up? …sigh), from the NMIN About page,

NMIN is funded by the Government of Canada through the Networks of Centres of Excellence (NCE) Program.

The NCEs seem to be firmly fixed on finding pathways to commercialization (from the NCE About page) Note: All is not as it seems,

Canada’s global economic competitiveness [emphasis mine] depends on making new discoveries and transforming them into products, services [emphasis mine] and processes that improve the lives of Canadians. To meet this challenge, the Networks of Centres of Excellence (NCE) offers a suite of programs that mobilize Canada’s best research, development and entrepreneurial [emphasis mine] expertise and focus it on specific issues and strategic areas.

NCE programs meet Canada’s needs to focus a critical mass of research resources on social and economic challenges, commercialize [emphasis mine] and apply more of its homegrown research breakthroughs, increase private-sector R&D, [emphasis mine] and train highly qualified people. As economic [emphasis mine] and social needs change, programs have evolved to address new challenges.

Interestingly, the NCE is being phased out,

As per the December 2018 NCE Program news, funding for the Networks of Centres of Excellence (NCE) Program will be gradually transferred to the New Frontiers in Research Fund (NFRF).

The new agency, NFRF, appears to have a completely different mandate, from the NFRF page on the Canada Research Coordinating Committee webspace,

The Canada Research Coordinating Committee designed the New Frontiers in Research Fund (NFRF) following a comprehensive national consultation, which involved Canadian researchers, research administrators, stakeholders and the public. NFRF is administered by the Tri-agency Institutional Programs Secretariat, which is housed within the Social Sciences and Humanities Research Council (SSHRC), on behalf of Canada’s three research granting agencies: the Canadian Institutes of Health Research, the Natural Sciences and Engineering Research Council and SSHRC.

The fund will invest $275 million over the next 5 years beginning in fiscal 2018-19, and $65 million ongoing, to fund international, interdisciplinary, fast-breaking and high-risk research.

NFRF is composed of three streams to support groundbreaking research.

  • Exploration generates opportunities for Canada to build strength in high-risk, high-reward and interdisciplinary research;
  • Transformation provides large-scale support for Canada to build strength and leadership in interdisciplinary and transformative research; and
  • International enhances opportunities for Canadian researchers to participate in research with international partners.

As you can see there’s no reference to commercialization or economic challenges.

Personally

Here at last is the second observation, I find it hard to believe that the government of Canada has given up on the idea of commercializing research and increasing the country’s economic competitiveness through research. Certainly, Langer’s virtual appearance at Vancouver Nanomedicine Day 2020, suggests that at least some corners of the Canadian research establishment are remaining staunchly entrepreneurial.

After all, the only Canadian government ministry with science in its name is this one: Innovation, Science and Economic Development Canada (ISED), as of Sept. 11, 2020.. (The other ‘science’ ministries are Natural Resources Canada, Environment and Climate Change Canada, Fisheries and Oceans Canada, Health Canada, and Agriculture and Agri-Food Canada.) ISED is not exactly subtle. Intriguingly the latest review on the state of science and technology in Canada was released on April 10, 2018 (from the April 10, 2018 Council of Canadian Academies CCA] news release),

Canada remains strong in research output and impact, capacity for R&D and innovation at risk: New expert panel report

While Canada is a highly innovative country, with a robust research base and thriving communities of technology start-ups, significant barriers—such as a lack of managerial skills, the experience needed to scale-up companies, and foreign acquisition of high-tech firms—often prevent the translation of innovation into wealth creation.[emphasis mine] The result is a deficit of technology companies growing to scale in Canada, and a loss of associated economic and social benefits.This risks establishing a vicious cycle, where successful companies seek growth opportunities elsewhere due to a lack of critical skills and experience in Canada guiding companies through periods of rapid expansion.

According to the CCA’s [2018 report] Summary webpage, it was Innovation, Science and Economic Development Canada which requested the report. (I wrote up a two-part commentary under one of my favourite titles: “The Hedy Lamarr of international research: Canada’s Third assessment of The State of Science and Technology and Industrial Research and Development in Canada.” Part 1 and Part 2)

I will be fascinated to watch the NFRF and science commercialization situations as they develop.

Connecting biological and artificial neurons (in UK, Switzerland, & Italy) over the web

A February 26, 2020 University of Southampton press release (also on EurekAlert) describes this work,

Research on novel nanoelectronics devices led by the University of Southampton enabled brain neurons and artificial neurons to communicate with each other. This study has for the first time shown how three key emerging technologies can work together: brain-computer interfaces, artificial neural networks and advanced memory technologies (also known as memristors). The discovery opens the door to further significant developments in neural and artificial intelligence research.

Brain functions are made possible by circuits of spiking neurons, connected together by microscopic, but highly complex links called ‘synapses’. In this new study, published in the scientific journal Nature Scientific Reports, the scientists created a hybrid neural network where biological and artificial neurons in different parts of the world were able to communicate with each other over the internet through a hub of artificial synapses made using cutting-edge nanotechnology. This is the first time the three components have come together in a unified network.

During the study, researchers based at the University of Padova in Italy cultivated rat neurons in their laboratory, whilst partners from the University of Zurich and ETH Zurich created artificial neurons on Silicon microchips. The virtual laboratory was brought together via an elaborate setup controlling nanoelectronic synapses developed at the University of Southampton. These synaptic devices are known as memristors.

The Southampton based researchers captured spiking events being sent over the internet from the biological neurons in Italy and then distributed them to the memristive synapses. Responses were then sent onward to the artificial neurons in Zurich also in the form of spiking activity. The process simultaneously works in reverse too; from Zurich to Padova. Thus, artificial and biological neurons were able to communicate bidirectionally and in real time.

Themis Prodromakis, Professor of Nanotechnology and Director of the Centre for Electronics Frontiers at the University of Southampton said “One of the biggest challenges in conducting research of this kind and at this level has been integrating such distinct cutting edge technologies and specialist expertise that are not typically found under one roof. By creating a virtual lab we have been able to achieve this.”

The researchers now anticipate that their approach will ignite interest from a range of scientific disciplines and accelerate the pace of innovation and scientific advancement in the field of neural interfaces research. In particular, the ability to seamlessly connect disparate technologies across the globe is a step towards the democratisation of these technologies, removing a significant barrier to collaboration.

Professor Prodromakis added “We are very excited with this new development. On one side it sets the basis for a novel scenario that was never encountered during natural evolution, where biological and artificial neurons are linked together and communicate across global networks; laying the foundations for the Internet of Neuro-electronics. On the other hand, it brings new prospects to neuroprosthetic technologies, paving the way towards research into replacing dysfunctional parts of the brain with AI [artificial intelligence] chips.”

I’m fascinated by this work and after taking a look at the paper, I have to say, the paper is surprisingly accessible. In other words, I think I get the general picture. For example (from the Introduction to the paper; citation and link follow further down),

… To emulate plasticity, the memristor MR1 is operated as a two-terminal device through a control system that receives pre- and post-synaptic depolarisations from one silicon neuron (ANpre) and one biological neuron (BN), respectively. …

If I understand this properly, they’ve integrated a biological neuron and an artificial neuron in a single system across three countries.
