Science events in Vancouver (Canada) for June 7 and June 13, 2013

Friday, June 7th, 2013

There’s a University of British Columbia CIHR (Canadian Institutes for Health Research) Café Scientifique event taking place tonight, June 7, 2013, from the event webpage,

June 7, 2013

Blusson Spinal Cord Centre [this is one of the buildings that form the Vancouver General Hospital complex]
7:00 pm

Map & Directions

Join ICORD engineer Dr. Peter Cripton and physician Dr. Peter Wing for refreshments and informal discussion about strategies and devices to prevent spinal cord injuries.
Moderated by Dr. Chris McBride, Executive Director, SCI-BC

No charge • Everyone welcome • Registration required.

You can register here but there is currently a waitlist. I think the reason for event’s popularity can be intuited by reading this event description,

Join ICORD engineer and UBC mechanical engineering prof. Peter Cripton and spine surgeon Dr. Peter Wing at the next Canadian Institutes of Health Research (CIHR) Café Scientifique for an informal discussion about strategies and devices to prevent spinal cord injuries.

The Café provides a forum for health researches to connect directly with the public and broad local research communities in an informal setting. Cripton and Wing will be joined by film and animation producer and injury prevention speaker Kirsten Sharp. [emphasis mine]

The words film and animation attracted my attention and I’m assuming the same would be true of others who might not usually attend a talk about spinal cord injuries.

For those who require a little more notice, there’s a Thursday, June 13, 2013 Women in Science event at the HR MacMillan Space Centre, from the event page,

Thursday, June 13, 7:00 pm
Transforming Human-Robot Interaction – Dr. Elizabeth Croft
Depictions of robots vary from the helpful humanoid to destructive, evil entities. In reality, most robots are used in lab or industrial settings.  These robots are fast, strong and accurate, but not ideal co-workers. They don’t communicate well with humans, and are not always designed for safety when in close proximity to people.  Dr. Croft is finding ways to help humans and robots to work together.
Dr. Elizabeth Croft, B.A.Sc. (88, Mech, UBC), M.A.Sc (92, Mech, Waterloo), Ph.D. (95, Mech, Toronto), PEng, FEC, FASME
Dr. Croft is a professor at UBC; NSERC Chair for Women in Science and Engineering, BC-Yukon at UBC; and leader of the WWEST program for women in engineering, science and technology.  The focus of this initiative is to promote science and engineering as a career choice for women and other under-represented groups, and to identify and eliminate barriers that result in attrition from these career paths. She is the founding faculty advisor for the UBC Engineering Tri-Mentoring Program, and is director of the Collaborative Advanced Robotics and Intelligent Systems Laboratory at UBC.

I found some additional information on the event page (at the bottom),

7:00 pm (doors open at 6:30 pm)
Admission by donation

As for the location, you really need to check out the map and the directions. The HR MacMillan Space Centre is one of two tenants (the other is the Museum of Vancouver) in a facility located in a park near Kitsilano beach. The Bard on the Beach Shakespeare festival which takes place beside the facility starts June 12, 2013. This is a very popular festival and June 13, 2013 is the festival’s opening night for its production of Hamlet. Taking the bus means a 10 -15 minute hike, as well as, the festival hubbub and parking in that area is likely to be at a premium.

Better photolithography and nanoscale manipulation and manufacturing (maybe) with flat lenses

Monday, May 27th, 2013

A flat spray-on lens sounded only mildly intriguing as per the May 23, 2012 University of British Columbia news release (UBC engineer helps pioneer flat spray-on optical lens) on EurekAlert. It was the May 24, 2013 news item on ScienceDaily that provided more exciting possibilities,

For the first time, scientists working at the National Institute of Standards and Technology (NIST) have demonstrated a new type of lens that bends and focuses ultraviolet (UV) light in such an unusual way that it can create ghostly, 3D images of objects that float in free space. The easy-to-build lens could lead to improved photolithography, nanoscale manipulation and manufacturing, and even high-resolution three-dimensional imaging, as well as a number of as-yet-unimagined applications in a diverse range of fields.

The May 24, 2013 NIST news release, which originated the news item, describes some of the optical principles at work,

An article published in the journal Nature* explains that the new lens is formed from a flat slab of metamaterial with special characteristics that cause light to flow backward—a counterintuitive situation in which waves and energy travel in opposite directions, creating a negative refractive index.

Naturally occurring materials such as air or water have a positive refractive index. You can see this when you put a straw into a glass of water and look at it from the side. The straw appears bent and broken as a result of the change in index of refraction between air, which has an index of 1, and water, which has an index of about 1.33. Because the refractive indices are both positive, the portion of the straw immersed in the water appears bent forward with respect to the portion in air.

The negative refractive index of metamaterials causes light entering or exiting the material to bend in a direction opposite what would occur in almost all other materials. For instance, if we looked at our straw placed in a glass filled with a negative-index material, the immersed portion would appear to bend backward, completely unlike the way we’re used to light behaving.

In 1967, Russian physicist Victor Veselago described how a material with both negative electric permittivity and negative magnetic permeability would have a negative index of refraction. (Permittivity is a measure of a material’s response to an applied electric field, while permeability is a measure of the material’s response to an applied magnetic field.)

Veselago reasoned that a material with a refractive index of -1 could be used to make a lens that is flat, as opposed to traditional refractive lenses, which are curved. A flat lens with a refractive index of -1 could be used to directly image three-dimensional objects, projecting a three-dimensional replica into free space.

A negative-index flat lens like this has also been predicted to enable the transfer of image details substantially smaller than the wavelength of light and create higher-resolution images than are possible with lenses made of positive-index materials such as glass.

It seems the metamateriels that solve the problem posed by lenses made of glass present a few problems of their own (from the NIST news release),

… For the past decade, scientists have made metamaterials that work at microwave, infrared and visible wavelengths by fabricating repeating metallic patterns on flat substrates. However, the smaller the wavelength of light scientists want to manipulate, the smaller these features need to be, which makes fabricating the structures an increasingly difficult task. Until now, making metamaterials that work in the UV has been impossible because it required making structures with features as small as 10 nanometers, or 10 billionths of a meter.

Moreover, because of limitations inherent in their design, metamaterials of this type designed for infrared and visible wavelengths have, so far, been shown to impart a negative index of refraction to light that is traveling only in a certain direction, making them hard to use for imaging and other applications that rely on refracted light.

To overcome these problems, researchers working at NIST took inspiration from a theoretical metamaterial design recently proposed by a group at the FOM Institute for Atomic and Molecular Physics in Holland. They adapted the design to work in the UV—a frequency range of particular technological interest.

According to co-authors Xu, Amit Agrawal and Henri Lezec, aside from achieving record-short wavelengths, their metamaterial lens is inherently easy to fabricate. It doesn’t rely on nanoscale patterns, but instead is a simple sandwich of alternating nanometer-thick layers of silver and titanium dioxide, the construction of which is routine. And because its unique design consists of a stack of strongly coupled waveguides sustaining backward waves, the metamaterial exhibits a negative index of refraction to incoming light regardless of its angle of travel.

This realization of a Veselago flat lens operating in the UV is the first such demonstration of a flat lens at any frequency beyond the microwave. By using other combinations of materials, it may be possible to make similarly layered metamaterials for use in other parts of the spectrum, including the visible and the infrared.

The metamaterial flat lens achieves its refractive action over a distance of about two wavelengths of UV light, about half a millionth of a meter—a focal length challenging to achieve with conventional refractive optics such as glass lenses. Furthermore, transmission through the metamaterial can be turned on and off using higher frequency light as a switch, allowing the flat lens to also act as a shutter with no moving parts.

“Our lens will offer other researchers greater flexibility for manipulating UV light at small length scales,” says Lezec. “With its high photon energies, UV light has a myriad of applications, including photochemistry, fluorescence microscopy and semiconductor manufacturing. That, and the fact that our lens is so easy to make, should encourage other researchers to explore its possibilities.”

I would have offered some information about what they are spraying onto the lens but neither the NIST nor the University of British Columbia (UBC) news releases provides any details about the ‘spray-on’ aspect of this flat lens. There is this from the UBC news release,

“The idea of a flat lens goes way back to the 1960s when a Russian physicist came up with the theory,” Chau [Kenneth Chau, an assistant professor in the School of Engineering at UBC's Okanagan campus] says. “The challenge is that there are no naturally occurring materials to make that type of flat lens. Through trial and error, and years of research, we have come up with a fairly simple recipe for a spray-on material that can act as that flat lens.”

The research team has developed a substance that can be affixed to surfaces like a glass slide and turn them into flat lenses for ultraviolet light imaging of biological specimens.

“Curved lenses always have a limited aperture,” he explains. “With a flat lens, suddenly you can make lenses with an arbitrary aperture size – perhaps as big as a football field.”

While the spray-on, flat lens represents a significant advancement in technology, it is only an important first step, Chau says.

“This is the closest validation we have of the original flat lens theory,” he says. “The recipe, now that we’ve got it working, is simple and cost-effective.

For those who want to pursue the research paper, here’s a link to and a citation for it,

All-angle negative refraction and active flat lensing of ultraviolet light by Ting Xu, Amit Agrawal, Maxim Abashin, Kenneth J. Chau, & Henri J. Lezec. Nature 497, 470–474 (23 May 2013) doi:10.1038/nature12158  Published online 22 May 2013

A peculiarly Canadian, national science festival: Science Rendezvous

Friday, May 10th, 2013

I stumbled across the notice in my Twitter feed (@frogheart) this morning (May 10, 2013) about Science Rendezvous, a Canadian national science festival which is taking place on Sat., May 11, 2013. You can find a map which lists all of the events across the country here.

I gather they are taking a low key (peculiarly Canadian) approach to publicizing this event, which I am happy to see. (The festival was first mentioned here in my Dec. 31, 2012 posting.) More than one event has foundered once the initial enthusiasm has foundered so, it’s usually better to build slowly.

There are events in Newfoundland & Labrador, Nova Scotia, New Brunswick, Ontario, Manitoba, Saskatchewan, Alberta, and British Columbia (BC). As I live in BC I will focus on the three cities hosting events.

Here are the events in Vancouver (Note: Links have been removed.),

Evelyn Fox Keller, Lee Smolin, or Kathleen M. Vogel may be speaking at a science event near you

Thursday, March 14th, 2013

More details are emerging about Evelyn Fox Keller’s April 2013 visit to western Canada (first mentioned in my Jan. 23, 2013 posting). Fox Keller is an eminent scholar as per this description, from my Oct. 29, 2012 posting about her talk in Halifax, Nova Scotia,

Before giving you details about where to go for a link [to her livestreamed Oct. 30, 2012 talk], here’s more about the talk and about Keller,

Fifty years ago, Thomas Kuhn irrevocably transformed our thinking about the sciences with the publication of The Structure of Scientific Revolutions. For all his success, debate about the adequacy and applicability of his formulation persists to this day. Are there scientific revolutions in biology? Molecular genetics, for example, is currently undergoing a major transformation in its understanding of what genes are and of what role they play in an organism’s development and evolution. Is this a revolution? More specifically, is this a revolution of the sort that Kuhn had in mind? How is language used? What implications can we draw from this?

Dr. Keller is the recipient of the prestigious MacArthur ‘Genius’ Award and author of many influential works on science, society and modern biology such as: A Feeling for the Organism: The Life and Work of Barbara McClintock (1983), Reflections on Gender and Science (1985), Secrets of Life, Secrets of Death: Essays on Language, Gender, and Science (1992), The Century of the Gene (2000), Making Sense of Life: Explaining Biological Development with Models, Metaphors and Machines (2002) and The Mirage of a Space Between Nature and Nurture (2010).

Keller Fox will be visiting the University of Calgary (Alberta) on April 1, the University of Alberta on April 2, and the University of British Columbia on April 4, 2013.  I’ve not found details about the University of Calgary visit but did find this for the University of Alberta visit (from the  Situating Science network node for the University of Alberta web page),

Tue., Apr. 2, 4:00 PM – , 6:00 PM

Dr. Keller visits U. Alberta as part of her travels as the Cluster Visiting Scholar.

Dr. Keller will speak at 4 pm in the Engineering and Technology Learning Centre, room 1-017d. There will be a reception directly after the talk.

I did try to find more information about where and who might be allowed to attend her University of British Columbia (UBC) visit on the UBC site (Science and Technology Studies colloquium webpage, which lists her visit) and on their Green College site but no more details were available.

The Perimeter Institute in Waterloo, Ontario (the other side of Canada) has announced, with full details, an April 3, 2013 talk by Lee Smolin. Smolin moved to Canada in 2000 to become a founding member of the Perimeter Institute as per the biographical information attached to this event announcement. From their Mar. 13, 2013 announcement,

Time Reborn(Live webcast)

Wednesday, April 3 @ 7:00 pm
Mike Lazaridis Theatre of Ideas
Perimeter Institute, Waterloo

Lee Smolin
Perimeter Institute

What is time? Is our perception of time passing an illusion which hides a deeper, timeless reality? Or is it real, indeed, the most real aspect of our experience of the world? Einstein said that, “the distinction between past, present, and future is only a stubbornly persistent illusion,” and many contemporary theorists agree that time emerges from a more fundamental timeless quantum universe. But in recent cosmological speculation, this timeless picture of nature seems to have reached a dead end, populated by infinite numbers of imagined unobservable universes.

In this talk, Lee Smolin explains why he changed his mind about the nature of time and has embraced the view that time is real and everything else, including the laws of nature, evolves. In a world in which time is real, the future is open and there is an essential role for human agency and imagination in envisioning and shaping a good future. Read More

Origins of Pacific sea life: crowdfunding a scientific expedition to the Danajon Bank

Tuesday, March 5th, 2013

The Danajon (pronounced Dana [as in dada] hon) Bank, a reef  in the Philippines, is believed to be where much of Pacific marine life originated. According to a March 5, 2013 University of British Columbia news release, a team of researchers and photographers have started a crowdfunding campaign on indiegogo to document and raise awareness of the beautiful and endangered Danajon Bank,

Marine scientists and the world’s top nature photographers are teaming up to reveal for the first time the beauty of a rare double-barrier reef in the Philippines – and the imminent threats it faces – with the help of citizens around the world.

One of only six double-barrier reefs in the world, Danajon Bank is an important evolutionary birthplace of fish and other animal species found all over the Pacific Ocean today. However, Danajon Bank suffers from overfishing and other human pressures, and is home to nearly 200 threatened species.

Expedition: Danajon Bank will send a team of conservationists and award-winning photographers to document this “centre of the centre” of biodiversity, with the ultimate goal of legally protecting the fragile reef system.

“Not many people have heard of Danajon Bank. We plan to change that,” says Prof. Amanda Vincent, director of Project Seahorse, a UBC-Zoological Society of London initiative. “Crowdfunding is a fantastic way to raise funds and inspire the public to take ownership of issues such as marine conservation, so we thought: why not start there?”

“There really is no better way to communicate the urgent need for marine conservation than through images that hit you in the head and the heart,” says Thomas P. Peschak, an International League of Conservation Photographers Fellow and one of the expedition photographers. His résumé includes multiple BBC Wildlife Photographer of the Year and World Press Photo awards.

The team is requesting $30,000 to fund their expedition, which will take place April 5 – 15, 2013, and each level of donation promises rewards, all of them photographic in nature (wordplay intended).

Here’s a little more about the team from the University of British Columbia (UBC) news release,

The Expedition: Danajon Bank team also includes world-renowned photographers Luciano Candisani, Claudio Contreras, and Michael Ready. Project Seahorse co-founders Amanda Vincent (UBC), Heather Koldewey (ZSL [Zoological Society of London]) and Nicholas Hill (ZSL) will act as scientific advisors.

In April, the expedition team will blog from the field at danajon-bank.tumblr.com, and you can follow their exploits on Twitter @projectseahorse and @ilcp.

Beginning in June, the photographs will be shown in a series of public exhibitions in Chicago, Hong Kong, Manila and London and published in a new book.

I wonder why Vancouver is not included as a stop for one of the public exhibitions. After all, Vancouver is between Hong Kong and Manila to the west and Chicago to the east. As well, it is a little unexpected to note the involvement of Project Seahorse as the campaign notes don’t make the reasons for that group’s participation obvious but the campaign video clarifies matters somewhat,

As of today, March 5, 2013 at 3:15 pm PST, they have raised $225 towards their goal with 28 days remaining. Surprisingly, the team doesn’t offer any ‘science’ rewards. You can get photographs, the project’s book of photographs, postcards, etc. but not a single reward features a chat with one of the scientists, or a special visit to a facility such as the Shedd Aquarium in Chicago, or an opportunity to be a member of the expedition.

In any event, I wish the expedition the best of luck both with raising funds and with their work.

Situating Science in Canada; excerpts from the Winter 2013 newsletter

Thursday, January 24th, 2013

Situating Science is a SSHRC (Social Science and Humanities Research Council) funded network for Canadian Science and Technology Studies (STS) and Philosophy and History of Science scholars amongst others who examine the social impacts of science both in the present and in the past. The network is in its seventh and final year of funding (sunsetting) although there are plans for the future as per its most recent newsletter. Here’s a brief description of Situating Science’s  recent activities along with a listing of activities taking place in various Canadian cities over the next several months, as well as, a hint about future plans, from the Winter 2013 newsletter,

Happy New Year!

It’s been a busy few months. Members of the Cluster are now able to present you with all the latest in this Winter 2013 newsletter. In this issue, the Social Sciences and Humanities Research Council of Canada’s Strategic Knowledge Cluster, Situating Science: Cluster for the Humanist and Social Study of Science (www.situsci.ca) is pleased to update you on activities …

Given our past successes, Cluster members plan to move forward with a few grant applications to sustain and initiate partnerships and activities. Some partners and stakeholders met in October to begin the planning process for a national and international partnership to explore sciences, technologies and their publics. They also plan to arrange to meet again this year to concretize plans for a sustainable network and national centre.

The Cluster hopes to build upon partnership activities with scholars and institutions in Southeast Asia and India. Members are currently planning to seek support for a Canada-Southeast Asia and India partnership to explore cosmopolitanism and circulation of knowledge.

The Cluster Centre and its many and varied local partners kept Dr. Evelyn Fox Keller busy during her 3.5 week fall visit to Halifax as the Cluster Visiting Scholar. Her time here allowed her to research genotypic plasticity, biological information and mathematical biology on top of participating in several activities, including a public lecture on “Paradigm Shifts and Revolutions in Contemporary Biology”. She then continued to Montreal to present and discuss her work at McGill [University] and UQAM [Université de Québec à Montréal] (CIRST) [Centre interuniversitaire de recherche sur la science et la technologie] and then to Toronto for discussions at York University, a University of Toronto IHPST [Institute for the History and Philosophy of Science and Technology] Brown Bag colloquium and a Wiegand Memorial Foundation Lecture on “Self-organization and God.” Select videos and podcasts of her public events are available on our website.

Dr. Anne Harrington, professor of History of Science at Harvard University, came to the Cluster Centre in October for a packed history of medicine luncheon conversation on “Culture in the Brain and Under the Skin”.

Simon Fraser University completes a successful mating dance while TRIUMF (Canada’s national laboratory for particle and nuclear physics) gets its groove on

Tuesday, January 15th, 2013

The Federal Government of Canada in the guise of the Canada Foundation for Innovation has just awarded $7.7M to Simon Fraser University (SFU) and its partners for a global innovation hub. From the Jan. 15, 2013 Canada Foundation for Innovation news release,

British Columbia’s research-intensive universities are coming together to create a global hub for materials science and engineering. Simon Fraser University, the University of Victoria, the University of British Columbia and the British Columbia Institute of Technology have received $7.7 million in funding from the Canada Foundation of Innovation to create the Prometheus Project — a research hub for materials science and engineering innovation and commercialization.

“Our goal with the Prometheus Project is to turn our world-class research capacity into jobs and growth for the people of British Columbia,” said Neil Branda, Canada Research Chair in Materials Science at Simon Fraser University and leader of the Prometheus Project. “We know that materials science is changing the way we create energy and fight disease. We think it can also help B.C.’s economy evolve.”

This project builds on a strong collective legacy of collaborating with industry. Researchers involved in the Prometheus Project have created 13 spin-off companies, filed 67 patents and have generated 243 new processes and products. [emphasis mine] Branda himself has founded a company called Switch Materials that seizes the power of advanced chemistry to create smarter and more efficient window coatings.

This funding will allow members of the research team to build their capacity in fabrication, device testing and advanced manufacturing, ensuring that they have the resources and expertise they need to compete globally.

There’s a bit more information about the Prometheus project in a Jan.15, 2013 backgrounder supplied by SFU,

Led by Neil Branda, a Canada Research Chair in Materials Science and SFU chemistry professor, The Prometheus Project is destined to become a research hub for materials science and engineering innovation, and commercialization globally.

It brings together 10 principal researchers, including Branda, co-founder of SFU’s 4D LABS (a materials research facility with capabilities at the nanoscale], and 20 other scientists at SFU, University of British Columbia, the University of Victoria and the British Columbia Institute of Technology. They will create new materials science and engineering (MS&E) technology innovations, which will trigger and support sustained economic growth by creating, transforming and making obsolete entire industries.

Working with internationally recognized industrial, government, hospital and academic collaborators, scientists at the Prometheus partners’ labs, including 4D LABS, a $40 million materials science research institute, will deliver innovations in three areas. The labs will:

  • Develop new solar-industry related materials and devices, including novel organic polymers, nanoparticles, and quantum dots, which will be integrated in low cost, high efficiency solar cell devices. The goal is to create a new generation of efficient solar cells that can compete in terms of cost with non-renewable technologies, surpassing older ones in terms of miniaturization and flexibility.
  • Develop miniaturized biosensors that can be used by individuals in clinical settings or at home to allow early detection of disease and treatment monitoring. They will be integrated into flexible electronic skins, allowing health conditions to be monitored in real-time.
  • Develop spintronics (magnetic devices) and quantum computing and information devices that will enable new approaches to significantly improve encrypted communication and security in financial transactions.

“This project will allow B.C.’s four most research intensive institutes to collaborate on fundamental materials research projects with a wide range of potential commercial applications,” notes Branda. “By engaging with a large community of industry, government and NGO partners, we will move this research out of the lab and into society to solve current and future challenges in important areas such as energy, health and communications.”

The Prometheus team already has a strong network of potential end users of resulting technologies. It is based on its members’ relationships with many of more than 25 companies in BC commercializing solar, biomedical and quantum computing devices.

Researchers and industries worldwide will be able to access Prometheus’s new capabilities on an open-access basis. [emphasis mine]

There are a few things I’d like to point out (a) 13 spin-off companies? There’s no mention as to whether they were successful, i.e., created jobs or managed a life beyond government funding. (b) Patents as an indicator for innovation? As I’ve noted many, many times that’s a very problematic argument to make. (c) New processes and products? Sounds good but there are no substantiating details.  (d) Given the emphasis on commercializing discoveries and business, can I assume that open-access to Prometheus’ capabilities means that anyone willing and able to pay can have access?

In other exciting SFU news which also affects TRIUMF, an additional $1M is being awarded by the Canada Foundation for Innovation to upgrade the ATLAS Tier-1 Data Analysis Centre. From the SFU backgrounder,

Led by Mike Vetterli, a physics professor at SFU and TRIUMF, this project involves collaborating with scientists internationally to upgrade a component of a global network of always-on computing centres. Collectively, they form the Worldwide Large Hadron Collider Computing Grid (WLCG).

The Canadian scientists collaborating with Vetterli on this project are at several research-intensive universities. They include Carleton University, McGill University, University of British Columbia, University of Alberta, University of Toronto, University of Victoria, Université de Montréal, and York University, as well as TRIUMF. It’s Canada’s national lab for particle and nuclear physics research.

The grid, which has 10 Tier-1 centres internationally, is essentially a gigantic storage and processing facility for data collected from the ATLAS  experiment. The new CFI funding will enable Vetterli and his research partners to purchase equipment to upgrade the Tier-1 centre at TRIUMF in Vancouver, where the equipment will remain.

ATLAS is a multi-purpose particle detector inside a massive atom-smashing collider housed at CERN, the world’s leading laboratory for particle physics in Geneva, Switzerland.

More than 3,000 scientists internationally, including Vetterli and many others at SFU, use ATLAS to conduct experiments aimed at furthering global understanding of how the universe was physically formed and operates.

The detector’s fame for being a window into nature’s true inner workings was redoubled last year. It helped scientists, including Vetterli and others at SFU, discover a particle that has properties consistent with the Higgs boson.

Peter Higgs, a Scottish physicist, and other scientists theorized in 1964 about the existence of the long-sought-after particle that is central to the mechanism that gives subatomic particles their mass.

Scientists now need to upgrade the WLCG to accommodate the massive volume of data they’re reviewing to confirm that the newly discovered particle is the Higgs boson. If it is, it will revolutionize the way we see mass in physics.

“This project will enable Canadian scientists to continue to play a leading role in ATLAS physics analysis projects such as the Higgs boson discovery,” says Vetterli. “Much more work and data are required to learn more about the Higgs-like particle and show that it is indeed the missing link to our understanding of the fundamental structure of matter.

There is one more Canada Foundation for Innovation grant to be announced here, it’s a $1.6M grant for research that will be performed at TRIUMF, according to the Jan. 13, 2013 news release from St. Mary’s University (Halifax, Nova Scotia),

Dr. Rituparna Kanungo’s newest research collaboration has some lofty goals: improve cancer research, stimulate the manufacturing of high-tech Canadian-made instrumentation and help explain the origin of the cosmos.

The Saint Mary’s nuclear physicist’s goal moved one step closer to reality today when the federal government announced $1.6 million in support for an advanced research facility that will allow her to recreate, purify, and condition rare isotopes that haven’t existed on the planet for millions of years.

The federal fiscal support from the Canada Foundation for Innovation together with additional provincial and private sector investment will allow the $4.5 million project to be operational in 2015.

“The facility will dramatically advance Canada’s capabilities for isolating, purifying, and studying short-lived isotopes that hold the key not only for understanding the rules that govern the basic ingredients of our everyday lives but also for crafting new therapies that could target and annihilate cancers cell-by-cell within the human body, “ said Dr Kanungo.

The CANadian Rare-isotope facility with Electron-Beam ion source (CANREB) project is led by Saint Mary’s University partnering with the University of Manitoba and Advanced Applied Physics Solutions, Inc. in collaboration with the University of British Columbia, the University of Guelph, Simon Fraser University, and TRIUMF. TRIUMF is Canada’s national laboratory for particle and nuclear physics. It is owned and operated as a joint venture by a consortium of Canadian universities that includes Saint Mary’s University.

As one of the nation’s top nuclear researchers (she was one of only two Canadians invited to speak at a Nobel Symposium last June about exotic isotopes), Dr. Kanungo has been conducting research at the TRIUMF facility for many years, carrying out analyses from her office at Saint Mary’s University together with teams of students. Her students also often spend semesters at the Vancouver facility.

As the project leader for the new initiative, she said TRIUMF is the ideal location because of its world leading isotope-production capabilities and its ability to produce clean, precise, controlled beams of selected exotic isotopes not readily available anywhere else in the world.

In recent studies in the U.S., some of these isotopes have been shown to have dramatic impact in treating types of cancer, by delivering radioactive payloads directly to the cancerous cells. Canada’s mastery of the technology to isolate, study, and control these isotopes will change the course of healthcare.

An integral part of the project is the creation of a new generation of high resolution spectrometer using precision magnets. Advanced Cyclotron Systems, Inc. a company in British Columbia, has been selected for the work with the hope that the expertise it develops during the venture will empower it to design and build precision-magnet technology products for cutting-edge projects all around the world.

Exciting stuff although it does seem odd that the federal government is spreading largesse when there’s no election in sight. In any case, bravo!

There’s one last piece of news, TRIUMF is welcoming a new member to its board, from its Jan. 14, 2013 news release,

Dr. Sylvain Lévesque, Vice-President of Corporate Strategy at Bombardier Inc., a world-leading manufacturer of innovative transportation solutions, has joined the Board of Management for TRIUMF, Canada’s national laboratory for particle and nuclear physics, for a three-year term.  Owned and operated by a consortium of 17 Canadian universities with core operating funds administered via a contribution agreement through National Research Council Canada, TRIUMF is guided by a Board that includes university vice-presidents of research, prestigious scientists, and leading members of Canada’s private sector.

Paul Young, Chair of TRIUMF’s Board and Vice President, Research at the University of Toronto, said, “We welcome the participation of Sylvain and his extensive experience at Bombardier.  TRIUMF is a national resource for basic research and yet we also fulfill a technological innovation mission for Canada.  Dr. Lévesque will be a valuable addition to the Board.”

Dr. Sylvain Lévesque earned his Ph.D. from MIT in Engineering and worked at McKinsey & Company before joining Bombardier in 1999.  He brings deep experience with large, technical organizations and a passion for science and engineering. [emphasis mine]  He said, “I am excited to work more closely with TRIUMF.  It has a track record of excellence and I am eager to provide guidance on where Canada’s industrial sector might draw greater strength from the laboratory.”

TRIUMF’s Board of Management reflects the unique status of TRIUMF, a laboratory operating for more than forty years as a joint venture from Canada’s leading research universities.  The consortium includes universities from Halifax to Victoria.

Is deep experience like wide experience or is it a whole new kind of experience helpful for ‘getting one’s groove on’? For anyone who’s curious, ‘getting one’s groove on’ involves dancing.

Poetry, science get togethers, and/or song in Vancouver (Canada)

Friday, January 11th, 2013

I’ve been asked on occasion how one (this was from another writer) keeps creative. Sometimes banging out one piece after another can exhaust every creative idea or approach you’ve ever had and your writing, or if you’re in another field, your work has become pedestrian and/or repetitive. It’s not possible to avoid the problem entirely but I find that checking out other writers (both in fields similar to my own and entirely dissimilar) and checking out events and projects that are in unrelated fields can help a lot. So, this is a potpourri of events some science-oriented and some not and some literary-themed events and some not, but all are taking place in Vancouver, BC, Canada sometime in January or February 2013.

Lunch Poems @ SFU

Time: 12-1pm

Place: Teck Gallery, Harbour Centre, 515 West Hastings St.

Cost: Free

Come to the Teck Gallery to enjoy two poetry readings. Stick around for a question and answer session after. This week’s sessions features the poetry of lunch poems @SFU features Daniel Zomparelli and Elizabeth Bachinsky.

There are also a couple of science-themed get-togethers,

Wednesday, January 16 [2013]

Café Scientifique

Time: 7-8pm

Place: CBC, 700 Hamilton St.

Cost: Free, reserve by emailing cafesci@sfu.ca

Café Scientifique: Stem cells and the treatment of congenital heart disease. New techniques that generate inducible pluripotent stem cells (iPSCs) represents a powerful new approach to the study and treatment of congenital heart disease and other genetic disorders. Dr. Glen Tibbits, of SFU’s Dept. of Biomedical Physiology and Kinesiology, will focus on how iPSCs can be used to investigate the causes of congenital heart diseases, create new strategies for their treatment and potentially lead to a new era of personalized medicine in managing patients with these disorders. Refreshments will also be served.

Note: There are four different Café Scientifique groups in Vancouver. One meets at the Railway Club but is organized (or at least seems to be organized) by folks at the University of British Columbia (UBC), another is the LSI (Life Sciences Institute) Café Scientifique  and this is definitely organized at UBC; there’s also the Canadian Institutes of Health (CIHR) Café Scientifique (Science on tap; next meeting:  Does Communication Really Matter in Cancer Care? on Jan. 30, 2013 at Steamworks Brewing Co. 375 Water Street, Vancouver) which is associated with UBC (again) and now,there is a fourth Café, this one organized at SFU. I wish these folks would get together and have one gathering place for their notices, as well as, putting up notices institution by institution.

For those who find the Café Scientifique plethora somewhat confusing, there is the ScienceOnlineVancouver meeting planned for Jan. 17, 2013. Thematically this is on target but the group is meeting at The Whip Restaurant and Gallery and Neighbourhood House rather than at Science World as is more usual.

Happy weekend!

Gluing blood vessels with mussel goo

Thursday, December 13th, 2012

The University of British Columbia [UBC] Dec. 11, 2012 news release states,

A University of British Columbia researcher has helped create a gel – based on the mussel’s knack for clinging to rocks, piers and boat hulls – that can be painted onto the walls of blood vessels and stay put, forming a protective barrier with potentially life-saving implications.

Co-invented by Assistant Professor Christian Kastrup while a postdoctoral student at the Massachusetts Institute of Technology, the gel is similar to the amino acid that enables mussels to resist the power of churning water. The variant that Kastrup and his collaborators created, described in the current issue of the online journal PNAS [Proceeings of the National Academy of Sciences of the US] Early Edition, can withstand the flow of blood through arteries and veins.

Here’s the citation and a link to the article (which is behind a paywall),

Painting blood vessels and atherosclerotic plaques with an adhesive drug depot by Christian J. Kastrup, Matthias Nahrendorf, Jose Luiz Figueiredo, Haeshin Lee, Swetha Kambhampati, Timothy Lee, Seung-Woo Cho, Rostic Gorbatov, Yoshiko Iwamoto, Tram T. Dang, Partha Dutta, Ju Hun Yeon, Hao Cheng, Christopher D. Pritchard, Arturo J. Vegas, Cory D. Siegel, Samantha MacDougall, Michael Okonkwo, Anh Thai, James R. Stone, Arthur J. Coury, Ralph Weissleder, Robert Langer, and Daniel G. Anderson.  PNAS, December 11, 2012 DOI: 10.1073/pnas.1217972110

For those of a more technical turn of mind, here’s the abstract (from PNAS),

The treatment of diseased vasculature remains challenging, in part because of the difficulty in implanting drug-eluting devices without subjecting vessels to damaging mechanical forces. Implanting materials using adhesive forces could overcome this challenge, but materials have previously not been shown to durably adhere to intact endothelium under blood flow. Marine mussels secrete strong underwater adhesives that have been mimicked in synthetic systems. Here we develop a drug-eluting bioadhesive gel that can be locally and durably glued onto the inside surface of blood vessels. In a mouse model of atherosclerosis, inflamed plaques treated with steroid-eluting adhesive gels had reduced macrophage content and developed protective fibrous caps covering the plaque core. Treatment also lowered plasma cytokine levels and biomarkers of inflammation in the plaque. The drug-eluting devices developed here provide a general strategy for implanting therapeutics in the vasculature using adhesive forces and could potentially be used to stabilize rupture-prone plaques.

The news release describes the work layperson’s terms,

The gel’s “sheer strength” could shore up weakened vessel walls at risk of rupturing – much like the way putty can fill in dents in a wall, says Kastrup, a member of the Department of Biochemistry and Molecular Biology and the Michael Smith Laboratories.

By forming a stable barrier between blood and the vessel walls, the gel could also prevent the inflammation that typically occurs when a stent is inserted to widen a narrowed artery or vein; that inflammation often counteracts the opening of the vessel that the stent was intended to achieve.

The widest potential application would be preventing the rupture of blood vessel plaque. When a plaque ruptures, the resulting clot can block blood flow to the heart (triggering a heart attack) or the brain (triggering a stroke). Mice treated with a combination of the gel and an anti-inflammatory steroid had more stable plaque than a control group of untreated mice.

“By mimicking the mussel’s ability to cling to objects, we created a substance that stays in place in a very dynamic environment with high flow velocities,” says Kastrup, a member of UBC’s Centre for Blood Research.

Robert Langer, one of the paper’s co-authors, was mentioned here in an Aug. 27, 2012 posting about nanoelectronics, tissue engineering, and medicine.
