Canada’s Situating Science in Fall 2014

Canada’s Situating Science cluster (network of humanities and social science researchers focused on the study of science) has a number of projects mentioned and in its Fall 2014 newsletter,

1. Breaking News
It’s been yet another exciting spring and summer with new developments for the Situating Science SSHRC Strategic Knowledge Cluster team and HPS/STS [History of Philosophy of Science/Science and Technology Studies] research. And we’ve got even more good news coming down the pipeline soon…. For now, here’s the latest.

1.1. New 3 yr. Cosmopolitanism Partnership with India and Southeast Asia
We are excited to announce that the Situating Science project has helped to launch a new 3 yr. 200,000$ SSHRC Partnership Development Grant on ‘Cosmopolitanism and the Local in Science and Nature’ with institutions and scholars in Canada, India and Singapore. Built upon relations that the Cluster has helped establish over the past few years, the project will closely examine the actual types of negotiations that go into the making of science and its culture within an increasingly globalized landscape. A recent workshop on Globalizing History and Philosophy of Science at the Asia Research Institute at the National University of Singapore helped to mark the soft launch of the project (see more in this newsletter).

ARI along with Manipal University, Jawaharlal Nehru University, University of King’s College, Dalhousie University, York University, University of Toronto, and University of Alberta, form the partnership from which the team will seek new connections and longer term collaborations. The project’s website will feature a research database, bibliography, syllabi, and event information for the project’s workshops, lecture series, summer schools, and artifact work. When possible, photos, blogs, podcasts and videos from events will be posted online as well. The project will have its own mailing list so be sure to subscribe to that too. Check it all out: www.CosmoLocal.org

2.1. Globalizing History and Philosophy of Science workshop in Singapore August 21-22 2014
On August 21 and 22, scholars from across the globe gathered at the Asia Research Institute at the National University of Singapore to explore key issues in global histories and philosophies of the sciences. The setting next to the iconic Singapore Botanical Gardens provided a welcome atmosphere to examine how and why globalizing the humanities and social studies of science generates intellectual and conceptual tensions that require us to revisit, and possibly rethink, the leading notions that have hitherto informed the history, philosophy and sociology of science.

The keynote by Sanjay Subrahmanyam (UCLA) helped to situate discussions within a larger issue of paradigms of civilization. Workshop papers explored commensurability, translation, models of knowledge exchange, indigenous epistemologies, commercial geography, translation of math and astronomy, transmission and exchange, race, and data. Organizer Arun Bala and participants will seek out possibilities for publishing the proceedings. The event partnered with La Trobe University and Situating Science, and it helped to launch a new 3 yr. Cosmopolitanism project. For more information visit: www.CosmoLocal.org

2.2. Happy Campers: The Summer School Experience

We couldn’t help but feel like we were little kids going to summer camp while our big yellow school bus kicked up dust driving down a dirt road on a hot summer’s day. In this case it would have been a geeky science camp. We were about to dive right into day-long discussions of key pieces from Science and Technology Studies and History and Philosophy of Science and Technology.

Over four and a half days at one of the Queen’s University Biology Stations at the picturesque Elbow Lake Environmental Education Centre, 18 students from across Canada explored the four themes of the Cluster. Each day targeted a Cluster theme, which was introduced by organizer Sergio Sismondo (Sociology and Philosophy, Queen’s). Daryn Lehoux (Classics, Queen’s) explained key concepts in Historical Epistemology and Ontology. Using references of the anti-magnetic properties of garlic (or garlic’s antipathy with the loadstone) from the ancient period, Lehoux discussed the importance and significance of situating the meaning of a thing within specific epistemological contexts. Kelly Bronson (STS, St. Thomas University) explored modes of science communication and the development of the Public Engagement with Science and Technology model from the deficit model of Public Understanding of Science and Technology during sessions on Science Communication and its Publics. Nicole Nelson (University of Wisconsin-Madison) explained Material Culture and Scientific/Technological Practices by dissecting the meaning of animal bodies and other objects as scientific artifacts. Gordon McOuat wrapped up the last day by examining the nuances of the circulation and translation of knowledge and ‘trading zones’ during discussions of Geographies and Sites of Knowledge.

2.3. Doing Science in and on the Oceans
From June 14 to June 17, U. King’s College hosted an international workshop on the place and practice of oceanography in celebration of the work of Dr. Eric Mills, Dalhousie Professor Emeritus in Oceanography and co-creator of the History of Science and Technology program. Leading ocean scientists, historians and museum professionals came from the States, Europe and across Canada for “Place and Practice: Doing Science in and on the Ocean 1800-2012”. The event successfully connected different generations of scholars, explored methodologies of material culture analysis and incorporated them into mainstream historical work. There were presentations and discussions of 12 papers, an interdisciplinary panel discussion with keynote lecture by Dr. Mills, and a presentation at the Maritime Museum of the Atlantic by Canada Science and Technology Museum curator, David Pantalony. Paper topics ranged from exploring the evolving methodology of oceanographic practice to discussing ways that the boundaries of traditional scientific writing have been transcended. The event was partially organized and supported by the Atlantic Node and primary support was awarded by the SSHRC Connection Grant.

2.4. Evidence Dead or Alive: The Lives of Evidence National Lecture Series

The 2014 national lecture series on The Lives of Evidence wrapped up on a high note with an interdisciplinary panel discussion of Dr. Stathis Psillos’ exploration of the “Death of Evidence” controversy and the underlying philosophy of scientific evidence. The Canada Research Chair in Philosophy of Science spoke at the University of Toronto with panelists from law, philosophy and HPS. “Evidence: Wanted Dead of Alive” followed on the heels of his talk at the Institute for Science, Society and Policy “From the ‘Bankruptcy of Science’ to the ‘Death of Evidence’: Science and its Value”.

In 6 parts, The Lives of Evidence series examined the cultural, ethical, political, and scientific role of evidence in our world. The series formed as response to the recent warnings about the “Death of Evidence” and “War on Science” to explore what was meant by “evidence”, how it is interpreted, represented and communicated, how trust is created in research, what the relationship is between research, funding and policy and between evidence, explanations and expertise. It attracted collaborations from such groups as Evidence for Democracy, the University of Toronto Evidence Working Group, Canadian Centre for Ethics in Public Affairs, Dalhousie University Health Law Institute, Rotman Institute of Philosophy and many more.

A December [2013] symposium, “Hype in Science”, marked the soft launch of the series. In the all-day public event in Halifax, leading scientists, publishers and historians and philosophers of science discussed several case studies of how science is misrepresented and over-hyped in top science journals. Organized by the recent winner of the Gerhard Herzberg Canada Gold Medal for Science and Engineering, Ford Doolittle, the interdisciplinary talks in “Hype” explored issues of trustworthiness in science publications, scientific authority, science communication, and the place of research in the broader public.

The series then continued to explore issues from the creation of the HIV-Crystal Meth connection (Cindy Patton, SFU), Psychiatric Research Abuse (Carl Elliott, U. Minnesota), Evidence, Accountability and the Future of Canadian Science (Scott Findlay, Evidence for Democracy), Patents and Commercialized Medicine (Jim Brown, UofT), and Clinical Trials (Joel Lexchin, York).

All 6 parts are available to view on the Situating Science YouTube channel.You can read a few blogs from the events on our website too. Some of those involved are currently discussing possibilities of following up on some of the series’ issues.

Canada’s ‘nano’satellites to gaze upon luminous stars

The launch (from Yasny, Russia) of two car battery-sized satellites happened on June 18, 2014 at 15:11:11 Eastern Daylight Time according to a June 18, 2014 University of Montreal (Université de Montréal) news release (also on EurekAlert).

Together, the satellites are known as the BRITE-Constellation, standing for BRIght Target Explorer. “BRITE-Constellation will monitor for long stretches of time the brightness and colour variations of most of the brightest stars visible to the eye in the night sky. These stars include some of the most massive and luminous stars in the Galaxy, many of which are precursors to supernova explosions. This project will contribute to unprecedented advances in our understanding of such stars and the life cycles of the current and future generations of stars,” said Professor Moffat [Anthony Moffat, of the University of Montreal and the Centre for Research in Astrophysics of Quebec], who is the scientific mission lead for the Canadian contribution to BRITE and current chair of the international executive science team.

Here’s what the satellites (BRITE-Constellatio) are looking for (from the news release),

Luminous stars dominate the ecology of the Universe. “During their relatively brief lives, massive luminous stars gradually eject enriched gas into the interstellar medium, adding heavy elements critical to the formation of future stars, terrestrial planets and organics. In their spectacular deaths as supernova explosions, massive stars violently inject even more crucial ingredients into the mix. The first generation of massive stars in the history of the Universe may have laid the imprint for all future stellar history,” Moffat explained. “Yet, massive stars – rapidly spinning and with radiation fields whose pressure resists gravity itself – are arguably the least understood, despite being the brightest members of the familiar constellations of the night sky.” Other less-massive stars, including stars similar to our own Sun, also contribute to the ecology of the Universe, but only at the end of their lives, when they brighten by factors of a thousand and shed off their tenuous outer layers.

BRITE-Constellation is both a multinational effort and a Canadian bi-provincial effort,

BRITE-Constellation is in fact a multinational effort that relies on pioneering Canadian space technology and a partnership with Austrian and Polish space researchers – the three countries act as equal partners. Canada’s participation was made possible thanks to an investment of $4.07 million by the Canadian Space Agency. The two new Canadian satellites are joining two Austrian satellites and a Polish satellite already in orbit; the final Polish satellite will be launched in August [2014?].

All six satellites were designed by the University of Toronto Institute for Aerospace Studies – Space Flight Laboratory, who also built the Canadian pair. The satellites were in fact named “BRITE Toronto” and “BRITE Montreal” after the University of Toronto and the University of Montreal, who play a major role in the mission.  “BRITE-Constellation will exploit and enhance recent Canadian advances in precise attitude control that have opened up for space science  the domain of very low cost, miniature spacecraft, allowing a scientific return that otherwise would have had price tags 10 to 100 times higher,” Moffat said. “This will actually be the first network of satellites devoted to a fundamental problem in astrophysics.”

Is it my imagination or is there a lot more Canada/Canadian being included in news releases from the academic community these days? In fact, I made a similar comment in my June 10, 2014 posting about TRIUMF, Canada’s National Laboratory for Particle and Nuclear Physics where I noted we might not need to honk our own horns quite so loudly.

One final comment, ‘nano’satellites have been launched before as per my Aug. 6, 2012 posting,

The nanosatellites referred to in the Aug.2, 2012 news release on EurekALert aren’t strictly speaking nano since they are measured in inches and weigh approximately eight pounds. I guess by comparison with a standard-sized satellite, CINEMA, one of 11 CubeSats, seems nano-sized. From the news release,

Eleven tiny satellites called CubeSats will accompany a spy satellite into Earth orbit on Friday, Aug. 3, inaugurating a new type of inexpensive, modular nanosatellite designed to piggyback aboard other NASA missions. [emphasis mine]

One of the 11 will be CINEMA (CubeSat for Ions, Neutrals, Electrons, & MAgnetic fields), an 8-pound, shoebox-sized package which was built over a period of three years by 45 students from the University of California, Berkeley, Kyung Hee University in Korea, Imperial College London, Inter-American University of Puerto Rico, and University of Puerto Rico, Mayaguez.

This 2012 project had a very different focus from this Austrian-Canadian-Polish effort. From the University of Montreal news release,

The nanosatellites will be able to explore a wide range of astrophysical questions. “The constellation could detect exoplanetary transits around other stars, putting our own planetary system in context, or the pulsations of red giants, which will enable us to test and refine our models regarding the eventual fate of our Sun,” Moffatt explained.

Good luck!

Canadian researchers develop test for exposure to nanoparticles*

The Canadian Broadcasting Corporation’s online news features a May 21, 2014 article by Emily Chung regarding research from the University of Toronto that may enable a simple skin test for determining nanoparticle exposure,

Canadian researchers have developed the first test for exposure to nanoparticles — new chemical technology found in a huge range of consumer products — that could potentially be used on humans.

Warren Chan, a University of Toronto [U of T] chemistry professor, and his team developed the skin test after noticing that some mice changed colour and others became fluorescent (that is, they glowed when light of certain colours were shone on them) after being exposed to increasing levels of different kinds of nanoparticles. The mice were being used in research to develop cancer treatments involving nanoparticles.

There is some evidence that certain types and levels of exposure may be harmful to human health. But until now, it has been hard to link exposure to health effects, partly due to the challenge of measuring exposure.

“There’s no way to determine how much [sic] nanoparticles you’ve been exposed to,” said Chan in an interview with CBCNews.ca.

There was one way to measure nanoparticle exposure in mice —  but it required the animals to be dead. At that point, they would be cut open and tests could be run on organs such as the liver and spleen where nanoparticles accumulate.

A May 14, 2014 article by Nancy Owano on phys.org provides more details (Note: Links have been removed),

They [researchers] found that different nanoparticles are visible through the skin under ambient or UV light. They found that after intravenous injection of fluorescent nanoparticles, they accumulate and can be observed through the skin. They also found that the concentration of these nanoparticles can be directly correlated to the injected dose and their accumulations in other organs.

In their discussion over selecting nanoparticles used in mouse skin, they said, “Gold nanoparticles are commonly used in molecular diagnostics and drug delivery applications. These nanomaterials were selected for our initial studies as they are easily synthesized, have a distinct ruby color and can be quantified by inductively coupled plasma atomic emission spectroscopy (ICP-AES).”

Work involved in the study included designing and performing experiments, pathological analysis, and data analysis. Their discovery could be used to better predict how nanoparticles behave in the body.

Here’s a link to and a citation for the paper,

Nanoparticle exposure in animals can be visualized in the skin and analysed via skin biopsy by Edward A. Sykes, Qin Dai, Kim M. Tsoi, David M. Hwang & Warren C. W. Chan. Nature Communications 5, Article number: 3796 doi:10.1038/ncomms4796 Published 13 May 2014

Alice’s Wonderlab: http://www.ime.pku.edu.cn/alice

I wonder if the organizers will be including an Open Forum as they did at the 13th IEEE nanotechnology conference in China. It sounds a little more dynamic and fun than any of the sessions currently listed for the Toronto conference but these things are sometimes best organized in a relatively spontaneous fashion rather than as one of the more formal conference events (from the 13th conference Open Forum),

This Open Forum will be run like a Rump Session to have a lively discussion of various topics of interest to the IEEE Nanotechnology Community. The key to the success of this Forum is participation from the audience with their own opinions and comments on any Nanotechnology subject or issue they can think of. We expect the session to be lively, interesting, controversial, opinionated and more. Here are some topics or issues to think about:

  1. When are we ever going to have a large scale impact of nanotechnology ? Shouldn’t we be afraid that the stakeholders (Tax payers, Politicians) are going to run out of patience ?
  2. Is there a killer app or apps on the horizon ?
  3. Is there a future for carbon nanotubes in electronics ? It has been 15 years + now….
  4. Is there a future for graphene in electronics ?
  5. Is there a future for graphene in anything ? Or will it just run its course on every application people did previously for carbon nanotubes ?
  6. As engineers, are we doing anything different from the physicists/chemists ? Looks like we are also chasing the same old : trying to publish in Nature, Science, and other similar journals with huge impact factor ? Are we prepared adequately to play in someone else’s game ? Should we even be doing it ?
  7. As engineers, aren’t we supposed to come up with working widgets closer to manufacturing ?
  8. As engineers, are we going to take responsibility for the commercial future of nanotechnology as has been done in all previous success stories ?

This list is by no means exhaustive. Please come up with your own questions/issues and speak up at the session.

Good luck with your abstract.

Getting the logos they deserve: 50 physicists and mathematicians

There are some 50 logos created by Dr. Prateek Lala of the University of Toronto (Canada) on behalf of various physicists and mathematicians. Before showing any of these clever logos, here’s a bit more about Dr. Lala’s logos in John Brownlee’s Feb. 5, 2014 article for Fast Company (Note: Links have been removed),

The scientific typographics were created by Dr. Prateek Lala, a physician and amateur calligrapher from Toronto. Inspired by the type biographies of Indian graphic designer Kapil Bhagat, Lala designed his logos to make the lives and discoveries of various scientists more engaging and immediately relatable to students.

Kelly Oakes in a Feb. 3, 2014 post for BuzzFeed features 20 of the logos and I’ve downloaded two of them for here,

James Clerk Maxwell (1831-1879) formulated the equations that describe electricity, magnetism, and optics as manifestations of the same phenomenon – the electromagnetic field. He’s also the namesake of Maxwell’s demon, a thought experiment in which a hypothetical demon violates the Second Law of Thermodynamics. Credit: Dr. Prateek Lala / Perimeter Institute

I particularly enjoy how Dr. Lala has introduced the ‘demon’ into the logo. And then, there’s this one,

There is a bit of a controversy regarding Franklin as many believe she should have received more acknowledgement for her role in Crick and Watson’s ‘discovery of DNA’. I last mentioned Franklin in an August 19, 2013 posting (scroll down half-way) featuring a rap, Rosalind Franklin vs Watson & Crick, which was written and performed by children as part  of Tom McFadden’s Battle Rap Histories of Epic Science (Brahe’s Battles) school science project. The rap does a very good job of summarizing the discovery and the controversy and the performance is of a professional grade.

Getting back to Dr. Lala’s logos, there’s a slide show of 50 logos on this Perimeter Institute for Theoretical Physics webpage. I selected this one from the slideshow for inclusion here,

Dr. Lala has created some infographics of his logos which are can be seen here at visual.ly or you can see one featuring 60 of his logos in a July 26, 2013 posting by Carolina Brandão Zanelli on her Art for Scientists blog. As well, the Perimeter Institute is offering a poster of Dr. Lala’s logos in the Fall 2013 issue of their Inside the Perimeter magazine available here.

I was a little curious about Dr. Lala and was able to find this on academia.edu,

Catching up with Vive Crop Protection—advanced insecticide formulations, marketing in the US, and more

Starting with the “and more” part of the headline, it’s great to have found an article describing Vive Crop’s technology in language I can understand, Sadly, I failed to see it until Dec. 26, 2013,. Titled “Vive La Crop! nanotech venture vive crop protection of toronto has developed a more eco-friendly way to keep pests, fungi and weeds out of farmers’ fields. and that’s just the beginning,” is written by Tyler Hamilton for the April 2012 issue of ACCN the Canadian Chemical News (L’Actualite chemique canadienne) and it answers many of the questions I’ve had about Vive Crop’s Allosperse technology,

Pesticides don’t have the best reputation when it comes to their potential impacts on human health, but even more concerning — for regulators especially — are the volatile organic solvents frequently relied on to deliver crop-protection chemicals to farmers’ fields.

The solvents themselves are often known carcinogens, not the kind of thing we want on farmland that grows soy, corn and wheat. And they’re not as effective as they could be. Farmers tend to overspray to make sure enough of the active ingredients in insecticides, fungicides and herbicides are dispersed across a field to be effective.

It’s why Vive Crop Protection, a Toronto-based nanotechnology company specializing in crop protection, has been attracting so much attention from some of the world’s biggest chemical companies. Vive Crop (formerly Vive Nano, and before that Northern Nanotechnologies) has done away with the need for volatile organic solvents.

At the heart of Vive Crop’s technology are polymer particles the company has trademarked under the name Allosperse, which measure less than 10 nanometres in size. It describes these particles as ultra- small cages — or “really tiny little FEDEX boxes” in the words of CEO [Chief Executive Officer] Keith Thomas — which hold active pesticide ingredients and are engineered to disperse evenly in water.

Even and thorough dispersal is critical. Avinash Bhaskar, an analyst at research firm Frost & Sullivan who has followed Vive Crop closely, says one of the biggest problems with pesticides is they tend to agglomerate, resulting in uneven, clustery distribution on fields. “You want uniform distribution on the soil,” Bhaskar says. “Vive Crop’s technology prevents agglomeration and this is a key differentiator in the market.”

How Vive Crop chemically engineers these Allosperse particles is the company’s core innovation. It starts by dissolving negatively charged polymers in water. The like charges repel so the polymers spread out in the solution. Then positively charged ions are added to the mix. These ions neutralize the charge around the polymers, causing the polymers to collapse around the ions and create a kind of nanocage — the Allosperse.

The company then filters out the positive and negative ions and loads up the empty cages with molecules of active pesticide ingredients. The cage itself is amphiphilic, meaning it has both water-attracting and water-repelling areas. In this case, the outer shell attracts water and the inner core doesn’t. “While in water the active ingredient, which also hates water, stays inside (the cages),” explains Vive Crop chief technology officer Darren Anderson. Because the outside of the cages like water, the particles freely and evenly disperse. “Once sprayed on the crop, the water droplets evaporate and the active ingredient gradually disperses from the particles that are left behind.” How does Vive Crop assure that the Allosperse cages are amphiphilic? “I can’t tell you the answer,” says Anderson. “It’s part of our secret sauce.”

What the company can say is that the polymer cages themselves are benign. Vive Crop makes them out of chitosans, found naturally in the shells of shrimp and other crustaceans, and polyacrylic acid, the super-absorbent material found in baby diapers.

Interestingly, the core technology appears to be based on a former student project,

The core technology was developed in the early 2000s by Jordan Dinglasan, a chemistry student from the Philippines who took up graduate studies at the University of Toronto. Dinglasan and fellow researchers at U of T’s Department of Chemistry, including Anderson and chemistry professor Cynthia Goh, decided in 2006 that they wanted to reach beyond the walls of academia and create a company to commercialize the technology.

At the time of the Hamilton article, the company had 30 employees. Since the April 2012 article, the company has been busy as I’ve written an Aug. 7, 2013 posting about the US Environmental Protection Agency’s (EPA) approval of Vive Crop’s VCP-01, Bifenthrin 10 DF insecticide for foliar use on crops, turf, and ornamentals. and a September 25, 2013 posting about funding for two Vive Crop projects from Sustainable Development Technology Canada.

Now in the last weeks of December 2013 Vive Crop has issued two more news releases. First, there’s the Dec. 17, 2013 Vive Crop news release announcing a marketing initiative with a US company, AMVAC Chemical Corporation, which is wholly owned by American Vanguard Corporation and is based in California,,

Vive Crop Protection, Inc. and AMVAC Chemical Corporation are pleased to announce a collaboration to develop and market an advanced insecticide formulation for multiple uses in the United States.  The products leverage Vive’s patented AllosperseT technology delivering enhanced agronomic performance and new application opportunities to AMVAC’s customers.

“We are quite excited about working with AMVAC to add to their portfolio of innovative products,” said Vive CEO Keith Thomas. “Vive is rapidly developing a strong pipeline of effective crop protection products for our partners and growers.”

“As part of AMVAC’s continued commitment to innovate and deliver products with the best technology available, we are very pleased to be working with and investigating this new technology from Vive” said AMVAC Eric Wintemute, CEO of AMVAC .

Vive Crop followed up with a Dec. 19, 2013 news release announcing another marketing initiative, this time with United Suppliers (based in Iowa, US),

United Suppliers, Inc. and Vive Crop Protection, Inc. are pleased to announce a collaboration to demonstrate and market advanced formulation technologies in the United States. Targeted to launch in the 2015 growing season, these technologies will leverage Vive’s patented AllosperseT delivery system to provide enhanced agronomic performance and new application opportunities to United Suppliers’ leading-edge owners and customers.

“We are pursuing the capabilities of getting more activity out of the products we are using in current and expanded applications,” said United Suppliers VP of Crop Protection and Seed Brett Bruggeman. “United Suppliers’ retail owners are in the best position to deliver new technology to growers.”

“We are quite excited about working with United Suppliers to provide innovative products to their customers,” said Vive CEO Keith Thomas. “Vive is rapidly developing a strong pipeline of effective crop protection products for our partners and growers.”

Put some iron in your perfume and in your drugs

A Nov. 28, 2013 University of Toronto (Ontario, Canada) news release (also on EurekAlert) by Sean Bettan describes a new ‘green’ process, featuring iron, for use in the drug and perfume industries,

University of Toronto researchers have developed a series of techniques to create a variety of very active iron-based catalysts necessary to produce certain compounds used in the drug and perfume industry. The new synthetic methods promise to be safer, more economical and more environmentally friendly than traditional industrial processes.

There’s not much detail in the news release about this interesting work,

“There is a research effort world-wide to make chemical processes more sustainable and green, by replacing the rare, expensive and potentially toxic elements used in hydrogenation, catalytic converters in cars, fuel cells for the efficient conversion of chemical energy into electricity, and silicone coatings, with abundant ions such as iron,” says U of T chemistry professor Robert Morris, principal investigator of a study reported in the November 29 issue of Science. “Iron is about 10,000 times cheaper to obtain than ruthenium. Less than 200 metric tons of platinum-type metals are mined in the world every year and not all of it can be recycled after use. They are not essential to life and can be toxic.”

“We found a way to make the ferrous form of iron behave in a catalytic process much more efficiently than a precious metal.  We did this by finding molecules containing nitrogen, phosphorus, carbon and hydrogen, that bond to, and enhance, the reactivity of iron,” says Morris.

The scientists inexpensively produced varieties of alcohol with different biological properties — which can be used in flavour and drug synthesis — and different smells, a property important to the perfume industry. In one example from the study, the precursor alcohol to a cancer treatment can be made using the hydrogenation process catalyzed by iron. Using iron, the resulting complex is often a better catalyst than the industrial one based on ruthenium.

Here’s a link to and a citation for the paper,

Amine(imine)diphosphine Iron Catalysts for Asymmetric Transfer Hydrogenation of Ketones and Imines by Weiwei Zuo, Alan J. Lough, Young Feng Li, & Robert H. Morris. Science 29 November 2013: Vol. 342 no. 6162 pp. 1080-1083 DOI: 10.1126/science.1244466

Occasionally, I write about green chemistry as I did in a Jan. 10, 2011 posting about a McGill University (Montreal, Quebec, Canada) green chemistry breakthrough and about cinnamon-based green chemistry.

Grand Challenges Canada funds 83 projects to improve global health

For the third year in a row (as per my Dec. 22, 2011 posting and my Nov. 22, 2012 posting), I’m featuring Grand Challenges Canada funding for its ‘Stars in Global Health’ programme . From the Grand Challenges Canada (GCC) Nov. 21, 2013 news release,

Imaginative: 83 Bold Innovations to Improve Global Health Receive Grand Challenges Canada Funding

Among novel ideas to reduce disease, save lives in developing world:
Diagnostic diapers to detect deadly rotavirus; Rolling water barrel;
Special yogurt offsets pesticides, heavy metals, toxins in food;
Inventive shoe, boot material releases bug repellent when walking

50 innovators from low- and middle-income countries,
plus 33 from Canada, share $9.3 million in seed grants

Grand Challenges Canada, funded by the Government of Canada, today extends seed grants of $100,000 each to 83 inventive new ideas for addressing health problems in resource-poor countries.

The Grand Challenges Canada “Stars in Global Health” program seeks breakthrough and affordable innovations that could transform the way disease is treated in the developing world — innovations that may benefit the health of developed world citizens as well.

Of the 83 grants announced today, 50 are given to innovators in 15 low- and middle-income nations worldwide and 33 to Canadian-originated projects, to be implemented in a total of 30 countries throughout the developing world.

“Innovation powers development leading to better health and more jobs. I feel proud that Canada, through Grand Challenges Canada, has supported almost 300 bold ideas to date in our Stars in Global Health program,” says Dr. Peter A. Singer, Chief Executive Officer of Grand Challenges Canada.  “This is one of the largest pipelines of innovations in global health in the world today.”

Says the Honourable Christian Paradis, Canadian Minister of International Development and Minister for La Francophonie: “Grand Challenges Canada’s portfolio of projects shows how innovators with bold ideas have the potential to make a big impact on global health.  By connecting game-changing ideas with some of the most pressing global health challenges, these projects will lead to sustainable and affordable health solutions in low- and middle-income countries.”

The portfolio of 83 creative, out-of-the-box ideas, selected through independent peer review from 451 applications, includes projects submitted by social entrepreneurs, private sector companies and non-government organizations as well as university researchers.  Among them:

Diagnostics

  • A simple, portable, dry, yeast-based blood screening test (Belize, Jamaica).  WHO estimates almost half of 46 million blood donations in low-income countries are inadequately tested;  in Africa up to 10% of new HIV infections are caused by transfusions.  A University of Toronto-developed yeast-based blood screening tool will detect combinations of diseases. Like baking yeast, it can be stored dry, and can be grown locally with minimal equipment and training, improving accessibility in rural areas.
  • A bedside, Litmus paper-like test to detect bronchitis (Brazil, India). Being pioneered at McMaster University with international collaborators, a simple sputum test will detect infectious and allergic bronchitis in adults and children, reducing mis-diagnosis in developing countries and saving resources: time, steroids, antibiotics.

Water, sanitation, hygiene and general health

  • Special yogurts formulated to offset the harm to health caused by heavy metals, pesticides and other toxics in food (Africa).  Between 2006-2009 in Nairobi, only 17% of the total maize sampled and 5% of feed was fit for human and animal consumption respectively. University of Western Ontario researchers have developed novel yogurts containing a bacteria that, in the stomach, sequesters certain toxins and heavy metals and degrades some pesticides.
  • Addressing arsenic-laced groundwater. In Bangladesh, 1 in 5 deaths (600,000 per year) occur due to groundwater arsenic, dubbed by WHO as the largest mass poisoning in history, with some 77 million people at risk.  Project 1) Toronto-based PurifAid will deploy new filtration units via franchised villagers who will filter and deliver purified water, perform maintenance, acquire new filters and dispose of old ones, which can be used to produce biofuels.  Project 2) A project based at the University of Calgary, meanwhile, will work to increase the use of Western Canadian lentils in Bangladeshi diets.  The crop is rich in selenium, which can decrease arsenic levels and improve health.
  • “WaterWheel” (India, Kenya, Mongolia).  This simple, innovative device from India is a wheeled water container that enables the collection and transport of 3 to 5 times as much water as usual per trip, as well as hygienic storage, saving valuable time for productive activities and improving health.

Malaria

  • A vaccine based on a newly-discovered antibody in men that prevents malaria infection in the placenta (Benin, Colombia).  Colombian men exposed to malaria are found to have antibodies that can prevent infection in the placenta of a pregnant woman. This University of Alberta finding forms the basis for developing a novel vaccine against several forms of malaria, which cause 10,000 maternal deaths and 200,000 stillbirths annually.
  • Insect-repellent clothing, footwear and wall plaster (East Africa).  1) In Tanzania, the Africa Technical Research Institute will lead the design and manufacture of attractive, affordable insecticide-treated clothing while 2) the Ifakara Health Institute will develop anti-mosquito footwear material that slowly releases repellents from the friction of walking.  A key advantage: no compliance or change in habits required.  3) Uganda’s Med Biotech Laboratories, meanwhile, will produce a colorful, insecticide-infused ‘plaster’ for the outside walls of African village homes.

Maternal and child health

  • Mothers Telling Mothers: improving maternal health through storytelling (Uganda).  Work by Twezimbe Development Association has found that stories told by mothers in their own words and reflecting shared realities are most likely to increase the number of moms seeking skilled health care, and convince policymakers to improve healthcare access.  This project will capture 3 to 5 minutes stories to be shared through digital media platforms and health clinics.

Mobile technology

  • Digital African Health Library (Sub-Saharan Africa).  The University of Calgary-led project is creating an app to support bedside care by medical doctors in Africa: a smartphone-accessible resource providing evidence-based, locally-relevant decision support and health information.  A pilot involving 65 doctors in Rwanda showed point of care answers to patient questions more than tripled to 43%, with self-reported improvement in patient outcomes.

Health care

  • Simple sticker helps track clean surfaces in healthcare facilities (Philippines).  WHO estimates that 10% to 30% of all patients in developing country health care facilities acquire an infection.   An innovative sticker for hospital surfaces developed by Lunanos Inc. changes colour when a cleaner is applied and fades color after a predetermined period of time, helping staff track and ensure cleanliness of equipment and other frequently touched surfaces.
  • “Mystery clients” to assess and improve quality of TB care (India).  India accounts for 25% of global tuberculosis (TB) incidence.  To evaluate variations in practice quality, and identify ways to improve TB management in India, this project, led by Canada’s McGill University, will send researchers into clinics posing as a patient with standard TB symptoms.  The project builds on earlier work related to angina, asthma and dysentery, which revealed incorrect diagnoses and treatment.

And many more.

A complete set of 83 short project descriptions, with links to additional project details, available photos / video, and local contact information, is available in the full news release online here: http://bit.ly/HOLt5b

Here’s a video for the one of the projects (filtering arsenic out of Bangladesh’s water),

I chose this project somewhat haphazardly. It caught my attention as I have written more than once about purification efforts and as it turns out, this is a Canada-based project (with a Bangladeshi partner, BRAC) from the University of Toronto.

You may have heard the video’s narrator mention scotch whiskey, here’s why (from the YouTube page hosting the project video,page),

We plan to roll out a new generation of filtration units which run on an organic by-product of the beverage industry. The units address many of the failings of existing devices (they require no power or chemicals and are very low maintenance).

This project gets still more interesting (from the full project description page),

Device for the Remediation and Attenuation of Multiple Pollutants (DRAM) removes 95% of arsenic from contaminated water within 5 minutes of exposure. With an estimated 600,000 deaths directly attributable to arsenic poisoning every year, these units hold the potential to save millions of lives. Existing solutions are too complicated and suffer from significant usability issues (2012 UNICEF study).

We will deploy our units through a franchise business model. [emphasis mine] Local villagers will filter and deliver purified water, perform maintenance, acquire new media, and dispose spent media. The current market leader, the Sono Filter, has less than 20% uptake (according to UNICEF). DRAM costs only 25% of this solution, has lower maintenance requirements (4-6 month media cycle vs. 2 week media cycle), higher durability, and can be retrofitted onto existing tube wells villagers use thereby requiring no behavior change. The spent media (which must be replaced every 4-6 months) can be used to produce biofuels, giving PurifAid a decisive capability over competitors.

With the assistance of our local partner BRAC (ranked #1 on Global Journal’s list of top NGOs in 2012) we will retrofit our units onto existing tubewells. Contaminated water is pumped from the tubewell into the unit where it passes into the bottom of the unit, rising up through a bed of the organic filter media, binding the arsenic. Clean water is displaced and forced out of the top of the unit and out through the built-in tap. Our community based solution will begin with a proof-of-concept installation in the Mujibnagar District (pop. 1.3 million). BRAC will assist in testing our filter water quality on the ground and these results will be used to obtain regulatory approval for our technology. We will then operationalize our community-run DRAM systems. A council of local stakeholders will nominate prospective franchisees amongst villagers. These villagers will replace filter media in 4 month intervals and order annual delivery of new media. We are securing partnerships with nearby distilleries to locally source the filter media. [emphasis mine] Disposal will be handled by a local caretaker who will store spent media in bulk before transferring it for use as biofuel. Caretaker salary, media sourcing, and delivery costs will be paid by charging a levy on customer households. PurifAid will monitor behavioural and health indicators to ascertain DRAM’s immediate and long-term impact. To this end PurifAid has partnered with Ashalytics, a start-up global health analytics company, to report operational issues, measure impact, and communicate important metrics to key staff and stakeholders via mobile phones. This results in an environmentally-friendly value chain that uses beverage industry waste, maximizing positive impact. If the Bangladesh installations are a success then this system can be introduced across the Indian subcontinent and in west Africa, where arsenic in groundwater poses a serious health problem. DRAM has the potential to improve the lives of millions globally.

After 18 months we envisage having installed 15 DRAM systems supplying 45 liters of purified water per day to 2,700 households. In order to ensure maintenance, 15 paid caretakers will operate the pumps and a driver will supply the caretakers with fresh media every 4-6 months. Biannually, new bulk media will be provided to storage unit in the village, spent media will in turn be taken to a plant and converted to biofuel. Villagers will invest collectively to purchase, install and operate DRAM on pre-existing tube wells – thus no behavioral changes needed.

Our filters employ a new water filtration technology. Our franchise model involves social and business innovation, empowering communities to manage their own water treatment under the stewardship of a local partner that manages 17 social businesses with combined annual revenues of $93m in 2011.

(Aside: Don’t they ask for a ‘dram’ of whiskey in the movies?) This project is intended to do more than purify water; it’s designed to create jobs. Bravo!

Now back to the news release for details about the countries and agencies involved,

The global portfolio of grants, broken down by region and country:

30 projects based in 6 African countries (16 in Kenya, 5 in Tanzania, 5 in Uganda, 2 in Nigeria and 1 each in Senegal and Ghana)

I have found it confusing that there’s a Grand Challenges Canada and the Bill and Melinda Gates Foundation has a Grand Challenges programme, both of which making funding announcements at this time of year. I did make some further investigations which I noted in my Dec. 22, 2011 posting,

Last week, the Bill & Melinda Gates Foundation announced a $21.1 M grant over three years for research into point-of-care diagnostic tools for developing nations. A Canadian nongovermental organization (NGO) will be supplementing this amount with $10.8 M for a total of $31.9 M. (source: Dec. 16, 2011 AFP news item [Agence France-Presse] on MedicalXpress.com)

At this point, things get a little confusing. The Bill & Melinda Gates Foundation has a specific program called Grand Challenges in Global Health and this grant is part of that program. Plus, the Canadian NGO is called Grand Challenges Canada (couldn’t they have found a more distinctive name?), which is funded by a federal Canadian government initiative known as the Development Innovation Fund (DIF). …

Weirdly, no one consulted with me when they named the Bil & Melinda Gates Foundation programme or the Canadian NGO.

University of Toronto’s (Canada) invisibility cloak

University of Toronto researchers, Michael Selvanayagam and George V. Eleftheriades, have offered a popular summary of their work. from the popular summary (on the website where they’ve published their academic paper),

We “see” a physical object by detecting electromagnetic waves scattered from the object. A device that can “correct” or cancel that scattering would take the notion of a magic invisibility cloak from the realm of science fiction to reality. In fact, such physical devices already exist, accomplishing their feat based on metamaterials that bend light around the object to be cloaked, “correcting” the scattering. Designing metamaterials with the right light-bending properties for this purpose is, however, quite challenging, and the designs often require a thick “cloak.” An alternative approach to this problem is “active cloaking”: surrounding the object to be cloaked with electromagnetic sources that are carefully tuned to cancel the electromagnetic field scattered by the object. In this work, we demonstrate the first experimental realization of such a thin active cloak for microwaves.

The sources we have used are specially designed antennas and phase shifters, which can be configured into thin layers with flexibility in shape. We have succeeded in cloaking a sizable metallic cylinder by properly tuning the phase of the radiation from the antennas so that the radiation cancels the field scattered by the cylinder. We have gone a step further than cloaking and have also demonstrated how the object can be disguised as another object by tuning the antennas in a controlled way. The catch with active cloaking, however, is that knowledge of the incident field is required to tune the antennas. To tackle this issue, we have discussed some potential solutions that also utilize the antennas as sensors to detect the incident field.

Future work along this line will aim to extend the bandwidth of the cloak (with respect to pulsed incident fields) as well as design active cloaks that can adaptively respond to an incident field.

A Nov. 12, 2013 news item on ScienceDaily, offers information augmenting the popular summary,

Professor George Eleftheriades and PhD student Michael Selvanayagam have designed and tested a new approach to cloaking — by surrounding an object with small antennas that collectively radiate an electromagnetic field. The radiated field cancels out any waves scattering off the cloaked object. Their paper ‘Experimental demonstration of active electromagnetic cloaking’ appears today in the journal Physical Review X.

“We’ve taken an electrical engineering approach, but that’s what we are excited about,” says Eleftheriades. “It’s very practical.”

Picture a mailbox sitting on the street. When light hits the mailbox and bounces back into your eyes, you see the mailbox. When radio waves hit the mailbox and bounce back to your radar detector, you detect the mailbox. Eleftheriades and Selvanyagam’s system wraps the mailbox in a layer of tiny antennas that radiate a field away from the box, cancelling out any waves that would bounce back. In this way, the mailbox becomes undetectable to radar.

The Nov. 13, 2013 University of Toronto news release, which originated the news item and was posted a day later, provides more specific details about the research,

“We’ve demonstrated a different way of doing it,” says Eleftheriades. “It’s very simple: instead of surrounding what you’re trying to cloak with a thick metamaterial shell, we surround it with one layer of tiny antennas, and this layer radiates back a field that cancels the reflections from the object.”

Their experimental demonstration effectively cloaked a metal cylinder from radio waves using one layer of loop antennas. The system can be scaled up to cloak larger objects using more loops, and Eleftheriades says the loops could become printed and flat, like a blanket or skin.

For now, the antenna loops must be manually attuned to the electromagnetic frequency they need to cancel. But in future, researchers say, they could function both as sensors and active antennas, adjusting to different waves in real time, much like the technology behind noise-cancelling headphones.

Work on developing a functional invisibility cloak began around 2006, but early systems were necessarily large and clunky – if you wanted to cloak a car, for example, in practice you would have to completely envelop the vehicle in many layers of metamaterials in order to effectively “shield” it from electromagnetic radiation. The sheer size and inflexibility of that approach makes it impractical for real-world uses.

Earlier attempts to make thin cloaks were not adaptive and active, and could work only for specific small objects.

The cloaking technology holds possiblities that go beyond obvious applications such as hiding military vehicles or conducting surveillance operations. For example, structures that interrupt signals from cellular base stations could be cloaked to allow signals to pass by freely.

The system can also alter the signature of a cloaked object, making it appear bigger, smaller, or even shifting it in space. And though their tests showed the cloaking system works with radio waves, re-tuning it to work with Terahertz (T-rays) or light waves could use the same principle as the necessary antenna technology matures.

Sustainable Development Technology Canada, Vive Crop, two projects, and $14.7M in funding

The Canadian government used to create Crown Corporations, a kind of quasi-government agency/ business corporation that was run as a not-for-profit operation. Sustainable Development Technology Canada (SDTC) bears some of the marks of a crown corporation (completely government-funded) but it’s self-described as a not-for-profit foundation. Before getting to the main event (Vive Crop) here’s a little bit from the SDTC Profile page,

Sustainable Development Technology Canada (SDTC) is a not-for-profit foundation that finances and supports the development and demonstration of clean technologies which provide solutions to issues of climate change, clean air, water quality and soil, and which deliver economic, environmental and health benefits to Canadians.

SDTC operates two funds aimed at the development and demonstration of innovative technological solutions. The SD Tech Fund™ supports projects that address climate change, air quality, clean water, and clean soil. The NextGen Biofuels Fund™ supports the establishment of first-of-kind large demonstration-scale facilities for the production of next-generation renewable fuels.

SDTC is clearly focused on the economy and entrepreneurship in addition to sustainability as per their Sept. 9, 2013 news release about  a recent $14.7M investment,

The Government of Canada is showing its commitment to a green Canadian economy with an in investment of $14.7 million to help four new clean technology projects from across the country reach commercialization. The announcement was made today by the Honourable Joe Oliver, Minister of Natural Resources, and Dr. Vicky Sharpe, President and CEO of Sustainable Development Technology Canada (SDTC).

“Canada must nurture highly skilled individuals and new ideas that will help our businesses innovate, secure new markets and create well-paying jobs,” said Minister Oliver. “By supporting advanced research and technology, our government is investing in Canadian prosperity and a cleaner environment.”

“The projects announced today are great examples of the Canadian innovation and entrepreneurship that characterizes SDTC’s portfolio, valued at more than $2 billion and brimming with innovative technological solutions,” said Vicky Sharpe, President and CEO of SDTC. “Canadian cleantech leaders are continuing to create economic opportunities and open up avenues to new export markets.”


The newly-funded projects are representative of the investment priorities established in the SD Business Cases™, a series of six reports published by SDTC that provide strategic insights into specific economic sectors (available in the Knowledge Centre section of the SDTC website at http://www.sdtc.ca/).

SDTC’s SD Tech Fund™ has committed $598 million to 246 clean technology projects. These figures include adjustments made to the portfolio.

Vive Crop, headquartered in Toronto, Ontario,  is a recipient for two of the four projects being funded. Here’s more about one of the projects from the Sept. 18, 2013 Vive Crop news release,

Vive Crop Protection is pleased to announce that it received an investment of $3.7 million from the Government of Canada through Sustainable Development Technology Canada (SDTC) to develop an improved pesticide application distribution method that will translate into greater efficiency and reduced wastage.

Vive’s Allosperse® particle will be used to hold pesticides and deliver them precisely where they need to go.

“Canada must nurture highly skilled individuals and new ideas that will help our businesses innovate, secure new markets and create well-paying jobs,” said Minister Oliver. “By supporting advanced research and technology, our government is investing in Canadian prosperity and a cleaner environment.”

“Canadian farmers want a more economical and effective way to protect their crops from pests,” said Keith Thomas, CEO, Vive Crop Protection. “Thanks to support from the Government of Canada through Sustainable Development Technology Canada, Vive Crop Protection will further develop the Allosperse platform, precisely targeting pesticides where they act on crops.”

The best crop protection happens when pesticides stay where they are intended to protect the crop, for example on a crop’s leaves or at its roots. Vive has developed Allosperse®, a tiny particle that has unique properties: it has a hydrophilic (water-loving) exterior and an oleophillic (oil-loving) interior. Pesticides, which are also oleophillic, are loaded into the particle before application to crops. The next generation of Allosperse particles will have increased stickiness to leaves, avoiding run-off during the rain, and will penetrate leaves and seeds to offer systemic plant protection. Finally, the specially-designed particles will control the movement of the particle through the soil, allowing it to target pests at the plant’s roots. Less product, and therefore less cost, would be required to achieve equivalent results, and growers can get better protection with less accidental surface water run-off and soil contamination.

I have written about Vive Crop previously (most recently in an Aug. 7, 2013 posting when they received approval from the US Environmental Protection Agency for an insecticide) and my curiosity about Allosperse particles has not yet been satisfied. What are the chemical constituents? In lieu of an answer to that question (it’s nowhere on the company website), I found more information about Vive Crop and its SDTC-funded projects in this latest round of funding. As I noted previously, Vive Crop is involved in two of the funded projects as per the Sept. 9, 2013 SDTC backgrounder,

2. Lead organization: Macrotek

Project Title: Novel MVI Acid Gas Scrubbing Technology Project

Environmental Benefits: Climate Change/Clean Air/Clean Water/Clean Soil

Economic Sector: Waste management

SDTC Investment: $2 million

Consortium Members:

Macrotek

Vive Crop Protection [emphasis mine]

Plasco Energy Group

Project Description:

To avoid injecting contaminants into the atmosphere, industries use chemical reactions to “scrub” exhaust before it is emitted from smokestacks. However, current scrubbing techniques use caustic and oxidizing reagents (materials used to produce a chemical reaction). Macrotek has developed a groundbreaking suite of technologies that scrub in a novel, cost-effective and efficient way. The technology is developed initially to eliminate hydrogen sulfide (H2S), which is a major component of acid rain, from industrial gas streams. The technology uses a regenerative reagent, drastically reducing reagent consumption. It also converts H2S into its elemental form of sulphur, eliminating the current need to treat sulphate byproduct in wastewater streams. When full life-cycle costs are considered, this technology could cost less than 50 percent of the operating costs of traditional scrubber technologies, while maintaining or improving contaminant removal efficiency. This technology has the potential to address a multitude of other pollutants, such as nitrogen oxides, simultaneously.
