Brain-to-brain communication, organic computers, and BAM (brain activity map), the connectome

Miguel Nicolelis, a professor at Duke University, has been making international headlines lately with two brain projects. The first one about implanting a brain chip that allows rats to perceive infrared light was mentioned in my Feb. 15, 2013 posting. The latest project is a brain-to-brain (rats) communication project as per a Feb. 28, 2013 news release on *EurekAlert,

Researchers have electronically linked the brains of pairs of rats for the first time, enabling them to communicate directly to solve simple behavioral puzzles. A further test of this work successfully linked the brains of two animals thousands of miles apart—one in Durham, N.C., and one in Natal, Brazil.

The results of these projects suggest the future potential for linking multiple brains to form what the research team is calling an “organic computer,” which could allow sharing of motor and sensory information among groups of animals. The study was published Feb. 28, 2013, in the journal Scientific Reports.

“Our previous studies with brain-machine interfaces had convinced us that the rat brain was much more plastic than we had previously thought,” said Miguel Nicolelis, M.D., PhD, lead author of the publication and professor of neurobiology at Duke University School of Medicine. “In those experiments, the rat brain was able to adapt easily to accept input from devices outside the body and even learn how to process invisible infrared light generated by an artificial sensor. So, the question we asked was, ‘if the brain could assimilate signals from artificial sensors, could it also assimilate information input from sensors from a different body?'”

Ben Schiller in a Mar. 1, 2013 article for Fast Company describes both the latest experiment and the work leading up to it,

First, two rats were trained to press a lever when a light went on in their cage. Press the right lever, and they would get a reward–a sip of water. The animals were then split in two: one cage had a lever with a light, while another had a lever without a light. When the first rat pressed the lever, the researchers sent electrical activity from its brain to the second rat. It pressed the right lever 70% of the time (more than half).

In another experiment, the rats seemed to collaborate. When the second rat didn’t push the right lever, the first rat was denied a drink. That seemed to encourage the first to improve its signals, raising the second rat’s lever-pushing success rate.

Finally, to show that brain-communication would work at a distance, the researchers put one rat in an cage in North Carolina, and another in Natal, Brazil. Despite noise on the Internet connection, the brain-link worked just as well–the rate at which the second rat pushed the lever was similar to the experiment conducted solely in the U.S.

The Duke University Feb. 28, 2013 news release, the origin for the news release on EurekAlert, provides more specific details about the experiments and the rats’ training,

To test this hypothesis, the researchers first trained pairs of rats to solve a simple problem: to press the correct lever when an indicator light above the lever switched on, which rewarded the rats with a sip of water. They next connected the two animals’ brains via arrays of microelectrodes inserted into the area of the cortex that processes motor information.

One of the two rodents was designated as the “encoder” animal. This animal received a visual cue that showed it which lever to press in exchange for a water reward. Once this “encoder” rat pressed the right lever, a sample of its brain activity that coded its behavioral decision was translated into a pattern of electrical stimulation that was delivered directly into the brain of the second rat, known as the “decoder” animal.

The decoder rat had the same types of levers in its chamber, but it did not receive any visual cue indicating which lever it should press to obtain a reward. Therefore, to press the correct lever and receive the reward it craved, the decoder rat would have to rely on the cue transmitted from the encoder via the brain-to-brain interface.

The researchers then conducted trials to determine how well the decoder animal could decipher the brain input from the encoder rat to choose the correct lever. The decoder rat ultimately achieved a maximum success rate of about 70 percent, only slightly below the possible maximum success rate of 78 percent that the researchers had theorized was achievable based on success rates of sending signals directly to the decoder rat’s brain.

Importantly, the communication provided by this brain-to-brain interface was two-way. For instance, the encoder rat did not receive a full reward if the decoder rat made a wrong choice. The result of this peculiar contingency, said Nicolelis, led to the establishment of a “behavioral collaboration” between the pair of rats.

“We saw that when the decoder rat committed an error, the encoder basically changed both its brain function and behavior to make it easier for its partner to get it right,” Nicolelis said. “The encoder improved the signal-to-noise ratio of its brain activity that represented the decision, so the signal became cleaner and easier to detect. And it made a quicker, cleaner decision to choose the correct lever to press. Invariably, when the encoder made those adaptations, the decoder got the right decision more often, so they both got a better reward.”

In a second set of experiments, the researchers trained pairs of rats to distinguish between a narrow or wide opening using their whiskers. If the opening was narrow, they were taught to nose-poke a water port on the left side of the chamber to receive a reward; for a wide opening, they had to poke a port on the right side.

The researchers then divided the rats into encoders and decoders. The decoders were trained to associate stimulation pulses with the left reward poke as the correct choice, and an absence of pulses with the right reward poke as correct. During trials in which the encoder detected the opening width and transmitted the choice to the decoder, the decoder had a success rate of about 65 percent, significantly above chance.

To test the transmission limits of the brain-to-brain communication, the researchers placed an encoder rat in Brazil, at the Edmond and Lily Safra International Institute of Neuroscience of Natal (ELS-IINN), and transmitted its brain signals over the Internet to a decoder rat in Durham, N.C. They found that the two rats could still work together on the tactile discrimination task.

“So, even though the animals were on different continents, with the resulting noisy transmission and signal delays, they could still communicate,” said Miguel Pais-Vieira, PhD, a postdoctoral fellow and first author of the study. “This tells us that it could be possible to create a workable, network of animal brains distributed in many different locations.”

Will Oremus in his Feb. 28, 2013 article for Slate seems a little less buoyant about the implications of this work,

Nicolelis believes this opens the possibility of building an “organic computer” that links the brains of multiple animals into a single central nervous system, which he calls a “brain-net.” Are you a little creeped out yet? In a statement, Nicolelis adds:

We cannot even predict what kinds of emergent properties would appear when animals begin interacting as part of a brain-net. In theory, you could imagine that a combination of brains could provide solutions that individual brains cannot achieve by themselves.

That sounds far-fetched. But Nicolelis’ lab is developing quite the track record of “taking science fiction and turning it into science,” says Ron Frostig, a neurobiologist at UC-Irvine who was not involved in the rat study. “He’s the most imaginative neuroscientist right now.” (Frostig made it clear he meant this as a complement, though skeptics might interpret the word less charitably.)

The most extensive coverage I’ve given Nicolelis and his work (including the Walk Again project) was in a March 16, 2012 post titled, Monkeys, mind control, robots, prosthetics, and the 2014 World Cup (soccer/football), although there are other mentions including in this Oct. 6, 2011 posting titled, Advertising for the 21st Century: B-Reel, ‘storytelling’, and mind control.  By the way, Nicolelis hopes to have a paraplegic individual (using technology Nicolelis is developing for the Walk Again project) kick the opening soccer/football to the 2014 World Cup games in Brazil.

While there’s much excitement about Nicolelis and his work, there are other ‘brain’ projects being developed in the US including the Brain Activity Map (BAM), which James Lewis notes in his Mar. 1, 2013 posting on the Foresight Institute blog,

A proposal alluded to by President Obama in his State of the Union address [Feb. 2013] to construct a dynamic “functional connectome” Brain Activity Map (BAM) would leverage current progress in neuroscience, synthetic biology, and nanotechnology to develop a map of each firing of every neuron in the human brain—a hundred billion neurons sampled on millisecond time scales. Although not the intended goal of this effort, a project on this scale, if it is funded, should also indirectly advance efforts to develop artificial intelligence and atomically precise manufacturing.

As Lewis notes in his posting, there’s an excellent description of BAM and other brain projects, as well as a discussion about how these ideas are linked (not necessarily by individuals but by the overall direction of work being done in many labs and in many countries across the globe) in Robert Blum’s Feb. (??), 2013 posting titled, BAM: Brain Activity Map Every Spike from Every Neuron, on his eponymous blog. Blum also offers an extensive set of links to the reports and stories about BAM. From Blum’s posting,

The essence of the BAM proposal is to create the technology over the coming decade
to be able to record every spike from every neuron in the brain of a behaving organism.
While this notion seems insanely ambitious, coming from a group of top investigators,
the paper deserves scrutiny. At minimum it shows what might be achieved in the future
by the combination of nanotechnology and neuroscience.

In 2013, as I write this, two European Flagship projects have just received funding for
one billion euro each (1.3 billion dollars each). The Human Brain Project is
an outgrowth of the Blue Brain Project, directed by Prof. Henry Markram
in Lausanne, which seeks to create a detailed simulation of the human brain.
The Graphene Flagship, based in Sweden, will explore uses of graphene for,
among others, creation of nanotech-based supercomputers. The potential synergy
between these projects is a source of great optimism.

The goal of the BAM Project is to elaborate the functional connectome
of a live organism: that is, not only the static (axo-dendritic) connections
but how they function in real-time as thinking and action unfold.

The European Flagship Human Brain Project will create the computational
capability to simulate large, realistic neural networks. But to compare the model
with reality, a real-time, functional, brain-wide connectome must also be created.
Nanotech and neuroscience are mature enough to justify funding this proposal.

I highly recommend reading Blum’s technical description of neural spikes as understanding that concept or any other in his post doesn’t require an advanced degree. Note: Blum holds a number of degrees and diplomas including an MD (neuroscience) from the University of California at San Francisco and a PhD in computer science and biostatistics from California’s Stanford University.

The Human Brain Project has been mentioned here previously. The  most recent mention is in a Jan. 28, 2013 posting about its newly gained status as one of two European Flagship initiatives (the other is the Graphene initiative) each meriting one billion euros of research funding over 10 years. Today, however, is the first time I’ve encountered the BAM project and I’m fascinated. Luckily, John Markoff’s Feb. 17, 2013 article for The New York Times provides some insight into this US initiative (Note: I have removed some links),

The Obama administration is planning a decade-long scientific effort to examine the workings of the human brain and build a comprehensive map of its activity, seeking to do for the brain what the Human Genome Project did for genetics.

The project, which the administration has been looking to unveil as early as March, will include federal agencies, private foundations and teams of neuroscientists and nanoscientists in a concerted effort to advance the knowledge of the brain’s billions of neurons and gain greater insights into perception, actions and, ultimately, consciousness.

Moreover, the project holds the potential of paving the way for advances in artificial intelligence.

What I find particularly interesting is the reference back to the human genome project, which may explain why BAM is also referred to as a ‘connectome’.

ETA Mar.6.13: I have found a Human Connectome Project Mar. 6, 2013 news release on EurekAlert, which leaves me confused. This does not seem to be related to BAM, although the articles about BAM did reference a ‘connectome’. At this point, I’m guessing that BAM and the ‘Human Connectome Project’ are two related but different projects and the reference to a ‘connectome’ in the BAM material is meant generically.  I previously mentioned the Human Connectome Project panel discussion held at the AAAS (American Association for the Advancement of Science) 2013 meeting in my Feb. 7, 2013 posting.

Chad Mirkin, spherical nucleic acids, and a new ‘periodic table’

There was a big splash in July 2012 with the announcement that Chad Mirkin’s team at Northwestern University (Chicago, Illinois) had devised a skin cream that penetrated the skin barrier to deliver medication (my July 4, 2012 posting),

A team led by a physician-scientist and a chemist — from the fields of dermatology and nanotechnology — is the first to demonstrate the use of commercial moisturizers to deliver gene regulation technology that has great potential for life-saving therapies for skin cancers.

The topical delivery of gene regulation technology to cells deep in the skin is extremely difficult because of the formidable defenses skin provides for the body. The Northwestern approach takes advantage of drugs consisting of novel spherical arrangements of nucleic acids. These structures, each about 1,000 times smaller than the diameter of a human hair, have the unique ability to recruit and bind to natural proteins that allow them to traverse the skin and enter cells.

Mirkin has just finished presenting (Feb. 15, 2013 and Feb. 17, 2013) more information about spherical nucleic acids and their implications at the AAAS  (American Association for the Advancement of Science) 2013 meeting in Boston, Massachusetts. From the Feb. 15, 2013 news release on EurekAlert,

Northwestern University’s Chad A. Mirkin, a world-renowned leader in nanotechnology research and its application, has invented and developed a powerful material that could revolutionize biomedicine: spherical nucleic acids (SNAs).

Potential applications include using SNAs to carry nucleic acid-based therapeutics to the brain for the treatment of glioblastoma, the most aggressive form of brain cancer, as well as other neurological disorders such as Alzheimer’s and Parkinson’s diseases. Mirkin is aggressively pursuing treatments for such diseases with Alexander H. Stegh, an assistant professor of neurology at Northwestern’s Feinberg School of Medicine.

“These structures are really quite spectacular and incredibly functional,” Mirkin said. “People don’t typically think about DNA in spherical form, but this novel arrangement of nucleic acids imparts interesting chemical and physical properties that are very different from conventional nucleic acids.”

Spherical nucleic acids consist of densely packed, highly oriented nucleic acids arranged on the surface of a nanoparticle, typically gold or silver.  [emphasis mine] The tiny non-toxic balls, each roughly 15 nanometers in diameter, can do things the familiar but more cumbersome double helix can’t do:

  • SNAs can naturally enter cells and effect gene knockdown, making SNAs a superior tool for treating genetic diseases using gene regulation technology.
  • SNAs can easily cross formidable barriers in the human body, including the blood-brain barrier and the layers that make up skin.
  • SNAs don’t elicit an immune response, and they resist degradation, resulting in longer lifetimes in the body.

“The field of medicine needs new constructs and strategies for treating disease,” Mirkin said. “Many of the ways we treat disease are based on old methods and materials. Nanotechnology offers the ability to rapidly create new structures with properties that are very different from conventional forms of matter.”

“We now can go after a whole new set of diseases,” Mirkin said. “Thanks to the Human Genome Project and all of the genomics research over the last two decades, we have an enormous number of known targets. And we can use the same tool for each, the spherical nucleic acid. We simply change the sequence to match the target gene. That’s the power of gene regulation technology.”

###

A member of President Obama’s Council of Advisors on Science and Technology, Mirkin is known for invention and development of biological and chemical diagnostic systems based upon nanomaterials. He is the inventor and chief developer of Dip-Pen Nanolithography, a groundbreaking nanoscale fabrication and analytical tool, and is the founder of four Chicago-based companies: AuraSense, AuraSense Therapeutics, Nanosphere and NanoInk.

Mirkin, in addition to his work with spherical nucleic acids, has been busy with other nanoparticles and possible dreams of a new ‘periodic table of elements’, from the Feb. 17, 2013 news release on EurekAlert,

Forging a new periodic table using nanostructures

Northwestern University’s Chad A. Mirkin, …, has developed a completely new set of building blocks that is based on nanoparticles and DNA. Using these tools, scientists will be able to build — from the bottom up, just as nature does — new and useful structures.

“We have a new set of building blocks,” Mirkin said. “Instead of taking what nature gives you, we can control every property of the new material we make. We’ve always had this vision of building matter and controlling architecture from the bottom up, and now we’ve shown it can be done.”

Using nanoparticles and DNA, Mirkin has built more than 200 different crystal structures with 17 different particle arrangements. Some of the lattice types can be found in nature, but he also has built new structures that have no naturally occurring mineral counterpart.

Mirkin can make new materials and arrangements of particles by controlling the size, shape, type and location of nanoparticles within a given particle lattice. He has developed a set of design rules that allow him to control almost every property of a material.

New materials developed using his method could help improve the efficiency of optics, electronics and energy storage technologies. “These same nanoparticle building blocks have already found wide-spread commercial utility in biology and medicine as diagnostic probes for markers of disease,” Mirkin added.

With this present advance, Mirkin uses nanoparticles as “atoms” and DNA as “bonds.” He starts with a nanoparticle, which could be gold, silver, platinum or a quantum dot, for example. The core material is selected depending on what physical properties the final structure should have.

He then attaches hundreds of strands of DNA (oligonucleotides) to the particle. The oligonucleotide’s DNA sequence and length determine how bonds form between nanoparticles and guide the formation of specific crystal lattices.

“This constitutes a completely new class of building blocks in materials science that gives you a type of programmability that is extraordinarily versatile and powerful,” Mirkin said. “It provides nanotechnologists for the first time the ability to tailor properties of materials in a highly programmable way from the bottom up.”

If I read these two news releases rightly, the process (nanoparticles as atoms and DNA as bonds), Mirkin uses to create new structures is the same process he has used to create spherical nucleic acids. Given Mirkin’s entrepreneurial inclinations, I am curious as to how many and what kind of patents might be ‘protecting’ this work.

Study tracks evolution of world’s first 500 bio-nano firms

Elicia Maine, a professor at Simon Fraser University’s Beedie School of Business, is presenting right now (9:45 am – 12:45 pm EST, Feb. 18, 2013) at the AAAS (American Association for the Advancement of Science) 2013 meeting in Boston, Massachusetts in a session titled, Confluence of Streams of Knowledge: Biotechnology and Nanotechnology, about her study on bio-nano firms. Here’s more about her and her work in a Feb. 15, 2013 news release from Simon Fraser University (SFU), Note: I have removed a link,

Elicia Maine, an SFU associate professor of technology management and strategy at the Beedie School of Business, has co-authored a study that puts bio-nano firms under the microscope.

They are a new breed of business at the intersection of biotechnology and nanotechnology.

Maine will unveil a groundbreaking study on bio-nano firms in a seminar she has co-organized (with James Utterback, a Massachusetts Institute of Technology professor) at the world’s largest science research meeting.

Maine’s presentation, followed by a panel discussion, will take place at the annual American Association for the Advancement of Science (AAAS) convention in Boston, Massachusetts on Monday, Feb. 18, 9:45 a.m.-12:45 p.m. (Pacific time) Location: Room 300, Hynes Convention Centre.

The study, the first of its kind, tracks the evolution of the world’s first 500 bio-nano firms from their inception until now. “We are interested in seeing when these firms developed or acquired nanotechnology and biotechnology capabilities, and what they have done with those capabilities in terms of integrating the knowledge into new products and processes,” says Maine.

“We’ve classified the pioneers of this new breed of firms at the confluence of biotechnology and nanotechnology based on their primary role in innovation. They cover the areas of biopharma, drug delivery, diagnostics, biomaterials, medical devices, suppliers and instrumentation, and bioinformatics.”

Unfortunately, this is an unpublished study (I haven’t been able to find any reference to it online) but there is a video of Maine talking about her research on bio-nano firms,

ETA Feb. 21, 2012, There was a second news release from SFU dated Feb. 18, 2012, which provided some additional information and quotes about Maine’s research,

The study’s authors have identified, classified and analysed more than 500 of the world’s first companies in the emerging bio-nano sector. Their data shows these companies are taking hold not just in technology hotbeds such as California’s Silicon Valley and the northeastern United States but also across the country, and in Europe.

“We have watched the ecosystem emerge in terms of the number and type of firms entering,” says Maine.  “This confluence of technology silos in the emerging bio-nano sector is enabling radical innovation, new products and connections that didn’t exist before. Some of the things we’re talking about are targeted drug delivery, tissue engineering, enhanced medical diagnostics and new therapeutics.”

Between 2005 and 2011, the number of bio-nano firms nearly doubled to 507, with more than 100 of them emerging in North America alone.

AAAS 2013 meeting in Boston,US and Canadian research excellence

The 2013 annual meeting for the American Association for the Advancement of Science (AAAS) will be held in Boston, Massachusetts from Feb. 14 – 18, 2013 with a much better theme this year, The Beauty and Benefits of Science, than last year’s, Flattening the World. (It didn’t take much to improve the theme, eh?)

Plenary speakers range from AAAS’s president, William N. Press to Nathan Myhrvold, a venture capitalist to astrophysicist, Robert Kirshner to Cynthia Kenyon, a molecular biologist to Sherry Turkle. From the AAAS webpage describing Turkle’s 2013 plenary lecture,

Sherry Turkle

Abby Rockefeller Mauzé Professor of the Social Studies of Science and Technology in the Program in Science, Technology, and Society, MIT

The Robotic Moment: What Do We Forget When We Talk to Machines?

Dr. Turkle is founder and director of the MIT Initiative on Technology and Self. She received a joint doctorate in sociology and personality psychology from Harvard University and is a licensed clinical psychologist. Her research focuses on the psychology of human relationships with technology, especially in the realm of how people relate to computational objects. She is an expert on mobile technology, social networking, and sociable robotics and a regular media commentator on the social and psychological effects of technology. Her most recent book is Alone Together: Why We Expect More from Technology and Less from Each Other.

Given my experience last year in the 2012 meeting media room, I’m surprised to see a social media session is planned, from the session webpage,

Engaging with Social Media
Communicating Science
Thursday, February 14, 2013: 3:00 PM-4:30 PM
Ballroom A (Hynes Convention Center)

In a constantly changing online landscape, what is the best way for scientists and engineers to engage the public through social media? This session will discuss how people are accessing science information via blogs and social networks and the importance of researchers getting involved directly. [emphasis mine]  Speakers will address the ways that researchers can create meaningful interactions with the public through social media.

Organizer: Cornelia Dean, The New York Times
Co-Organizer: Dennis Meredith, Science Communication Consultant
Moderator: Carl Zimmer, Independent Science Journalist

Speakers:
XXXX Scicurious, Neurotic Physiology
Science Blogging for Fun and Profit
Christie Wilcox, University of Hawaii
Science in a Digital Age
Dominique Brossard, University of Wisconsin
Science and the Public in New Information Environments

I’d love to see how the theme of ‘researcher engaging directly’ gets developed. In theory, I have no problems with the concept. Unfortunately, those words are sometimes code for this perspective, ‘only experts (scientists/accredited journalists) should discuss or write about science’. A couple of quick comments, my Jan. 13, 2012 posting featured an interview with Carl Zimmer, this session’s moderator, about his science tattoo book and Dominique Brossard, one of the speakers, was last mentioned here in my Jan. 24, 2013 posting titled, Tweet your nano, in the context of a research study on social media and nanotechnology.

In keeping with the times (as per my Jan. 28, 2013 posting about the colossal research prizes for the Graphene and Human Brain Project initiatives), the 2012 AAAS annual meeting features a Brain Function and Plasticity thread or subtheme. There’s this session amongst others,

The Connectome: From the Synapse to Brain Networks in Health and Disease
Brain Function and Plasticity
Saturday, February 16, 2013: 8:30 AM-11:30 AM
Room 304 (Hynes Convention Center)

A series of innovative studies are being done to map the brain from the molecular to the systems level both structurally and functionally. At the synaptic level, how neurotransmitters, their receptors, and signaling pathways influence neural function and plasticity is becoming much better understood. Integrating neuronal function at the level of single neurons and groups of neurons into larger circuits at the anatomical level in the mammalian brain, while a daunting task, is being studied by advanced imaging techniques requiring vast amounts of information storage and processing. To integrate local circuit function with whole brain function, understanding the structure and processing of brain networks is critical. A major project to accomplish this task, the Human Connectome Project, is in the process of integrating the structure and function of brain networks using the most advanced imaging and analysis techniques in 1,200 people, including twins and their nontwin siblings. This step will allow for major new insights into not only brain structure and function, but also their genetic underpinnings. Comparing this information in both the normal brain and in different brain disorders such as neurodegenerative diseases is providing novel insights into how understanding brain function from the molecular to the systems level will provide insights into normal brain function and disease pathogenesis as well as provide new treatment strategies.

What’s Hot in Cold
Sunday, February 17, 2013: 8:30 AM-11:30 AM
Room 308 (Hynes Convention Center)

The study of ultracold atoms and molecules is now the frontier of low-temperature science, reaching temperatures of a few hundred picokelvin above absolute zero. This field was made possible by a technique that did not exist 30 years ago: laser cooling of atoms. It is hardly obvious that the laser, which produces the most intense light on Earth and is routinely used in industrial applications for cutting and welding medal, would also provide the most powerful coolant. Such are the surprises of science, where a breakthrough in one area transforms others in unexpected ways. Since 1997, eight Nobel Laureates in physics have been recognized for contributions to ultracold atomic and molecular science, which has become one of the most vibrant fields in physics, cutting across traditional disciplinary boundaries, e.g., atomic, molecular, and optical; condensed matter; statistical physics; and nuclear and particle physics. This field builds on two accomplishments that it was the first to achieve: first, the production of quantum degenerate matter using a wide range of elements and, second, exquisite control of quantum degenerate matter at the atomic level. These have led to record low temperatures, ultraprecise atomic clocks, and new forms of quantum matter that generalize ideas from magnetism superconductivity and graphene physics.

Introduction to Canadian Research Excellence: Evidence & Examples
Friday, February 15, 2013: 11:00 AM-12:00 PM
Room 205 (Hynes Convention Center)

The Canada Pavilion in the Exhibit Hall gives a taste of what lies north of Boston and the 49th parallel. Join us at this workshop to learn about opportunities in Canada for research and study. Canada recently completed a comprehensive analysis of its domestic science and technology strengths. The final report of the expert panel of the Council of Canadian Academies will be presented, including the use of global benchmarks and insights on international collaborations. Two of the drivers for Canadian excellence will be introduced: large-scale science facilities in key fields and a system of targeted fellowships and research chairs that recruit globally.

Coordinator:

Tim Meyer, TRIUMF

Presenters:

Tim Meyer, TRIUMF,
Chad Gaffield, Social Sciences and Humanities Research Council of Canada
Eliot Phillipson, University of Toronto

“Introduced,” really? Large scale science facilities are not new in Canada or anywhere else for that matter and the programmes of targeted fellowships have been around long enough and successful enough that it is being copied.

First, there was the Canada Research Chair programme, which was instituted in 2000. From the About Us page (Note: A link has been removed),

The Canada Research Chairs program stands at the centre of a national strategy to make Canada one of the world’s top countries in research and development. [emphasis mine]

In 2000, the Government of Canada created a permanent program to establish 2000 research professorships—Canada Research Chairs—in eligible degree-granting institutions across the country.

The Canada Research Chairs program invests $300 million per year to attract and retain some of the world’s most accomplished and promising minds.

This was programme was followed up with the Canada Excellence Research Chairs Program in 2008, from the Background page (Note: A link has been removed),

Launched in 2008, the Canada Excellence Research Chairs (CERC) Program supports Canadian universities in their efforts to build on Canada’s growing reputation as a global leader in research and innovation. The program awards world-renowned researchers and their teams up to $10 million over seven years to establish ambitious research programs at Canadian universities. These awards are among the most prestigious and generous available globally.

In May 2010, the first group of Canada Excellence Research Chairs was announced. Selected through a rigorous, multilevel peer review process, these chairholders are helping Canada build a critical mass of expertise in the four priority research areas of the federal government’s science and technology strategy …

Here’s an excerpt from my Feb. 21, 2012 posting,

Canadians have been throwing money at scientists for some years now (my May 20, 2010 posting about the Canada Excellence Research Chairs programme). We’ve attempted to recruit from around the world with our ‘research chairs’ and our ‘excellence research chairs’ and our Network Centres of Excellence (NCE) all serving as enticements.

The European Research Council (ERC) has announced that they will be trying to beat us at our own game at the AAAS 2012 annual meeting in Vancouver (this new ERC programme was launched in Boston, Massachusetts in January 2012).

The Canadian report these folks will be discussing was released in Sept. 2012 and was  featured here in a two-part commentary,

The State of Science and Technology in Canada, 2012 report—examined (part 1: the executive summary)

The State of Science and Technology in Canada, 2012 report—examined (part 2: the rest of the report)

My Sept. 27, 2012 posting features my response to the report’s launch on that day.

As for the AAAS 2013 annual meeting, there’s a lot, lot more of it and it’s worth checking out, if for no other reason than to anticipate the types of science stories you will be seeing in the coming months.
