Frogs: monitoring them, finding new species, and research about the golden ones in Panama

I have three frog-oriented items and while they’re not strictly speaking in my usual range of topics, given this blog’s name and the fact I haven’t posted a frog piece in quite a while, it seems this is a good moment to address that lack.

Monitoring frogs and amphibians at Trent University (Ontario, Canada)

From a March 23, 2015 Trent University news release,

With the decline of amphibian populations around the world, a team of researchers led by Trent University’s Dr. Dennis Murray will seek to establish environmental DNA (eDNA) monitoring of amphibian occupancy and aquatic ecosystem risk assessment with the help of a significant grant of over $596,000 from the Natural Sciences and Engineering Research Council of Canada (NSERC).

Awarded to Professor Murray, a Canada research chair in integrative wildlife conservation, bioinformatics, and ecological modelling and professor at Trent University along with colleagues Dr. Craig Brunetti of the Biology department, and Dr. Chris Kyle of the Forensic Science program, and partners at Laurentian University, University of Toronto, McGill University, Ontario Ministry of Natural Resources and Forestry and Environment Canada, the grant will support the development of tools that will promote a cleaner aquatic environment.

The project will use amphibian DNA found in natural breeding habitats to determine the presence and abundance of amphibians as well as their pathogens. This new technology capitalizes on Trent University’s expertise and infrastructure in the areas of wildlife DNA and water quality.

“We’re honoured to have received the grant to help us drive the project forward,” said Prof. Murray. “Our plan is to place Canada, and Trent, in a leadership position with respect to aquatic wildlife monitoring and amphibian conservation.”

Amphibian populations are declining worldwide, yet in Canada, amphibian numbers are not monitored closely, meaning changes in their distribution or abundance may be unnoticeable. Amphibian monitoring in Canada is conducted by citizen scientists who record frog breeding calls when visiting bodies of water during the spring. However, the lack of formalized amphibian surveys leaves Canada in a vulnerable position regarding the status of its diverse amphibian community.

Prof. Murray believes that the protocols developed from this project could revolutionize how amphibian populations are monitored in Canada and in turn lead to new insights regarding the population trends for several amphibian species across the country.

Here’s more about NSERC and Trent University from the news release,

Trent’s Peterborough campus boasts award-winning architecture in a breathtaking natural setting on the banks of the Otonabee River, just 90 minutes from downtown Toronto, while Trent University Durham delivers a distinct mix of programming in the GTA.

Trent University’s expertise in water quality could be traced to its proximity to Canada’s Experimental Lakes Area (ELA), a much beleaguered research environment due to federal political imperatives. You can read more about the area and the politics in this Wikipedia entry. BTW, I am delighted to learn that it still exists under the auspices of the International Institute for Sustainable Development (IISD),

Taking this post into nanotechnology territory while mentioning the ELA, Trent University published a Dec. 8, 2014 news release about research into silver nanoparticles,

For several years, Trent University’s Dr. Chris Metcalfe and Dr. Maggie Xenopoulos have dedicated countless hours to the study of aquatic contaminants and the threat they pose to our environment.

Now, through the efforts of the International Institute for Sustainable Development (IISD), their research is reaching a wider audience thanks to a new video (Note: A link has been removed).

The video is one of a five-part series being released by the IISD that looks into environmental issues in Canada. The video entitled “Distilling Science at the Experimental Lakes Area: Nanosilver” and featuring Professors Metcalfe and Xenopoulos profiles their research around nanomaterials at the Experimental Lakes Area.

Prof. Xenopolous’ involvement in the project falls in line with other environmental issues she has tackled. In the past, her research has examined how human activities – including climate change, eutrophication and land use – affect ecosystem structure and function in lakes and rivers. She has also taken an interest in how land use affects the material exported and processed in aquatic ecosystems.

Prof. Metcalfe’s ongoing research on the fate and distribution of pharmaceutical and personal care products in the environment has generated considerable attention both nationally and internationally.

Together, their research into nanomaterials is getting some attention. Nanomaterials are submicroscopic particles whose physical and chemical properties make them useful for a variety of everyday applications. They can be found in certain pieces of clothing, home appliances, paint, and kitchenware. Initial laboratory research conducted at Trent University showed that nanosilver could strongly affect aquatic organisms at the bottom of the food chain, such as bacteria, algae and zooplankton.

To further examine these effects in a real ecosystem, a team of researchers from Trent University, Fisheries and Oceans Canada and Environment Canada has been conducting studies at undisclosed lakes in northwestern Ontario. The Lake Ecosystem Nanosilver (LENS) project has been monitoring changes in the lakes’ ecosystem that occur after the addition of nanosilver.

“In our particular case, we will be able to study and understand the effects of only nanosilver because that is the only variable that is going to change,” says Prof. Xenopoulos. “It’s really the only place in the world where we can do that.”

The knowledge gained from the study will help policy-makers make decisions about whether nanomaterials can be a threat to aquatic ecosystems and whether regulatory action is required to control their release into the environment.

Here’s more about the shapeshifting and how the scientists figured out what the frogs were doing (from a March 23, 2015 Case Western Research University news release on EurekAlert; Note: A link has been removed),

A frog in Ecuador’s western Andean cloud forest changes skin texture in minutes, appearing to mimic the texture it sits on.

Originally discovered by a Case Western Reserve University PhD student and her husband, a projects manager at Cleveland Metroparks’ Natural Resources Division, the amphibian is believed to be the first known to have this shape-shifting capability.

But the new species, called Pristimantis mutabilis, or mutable rainfrog, has company. Colleagues working with the couple recently found that a known relative of the frog shares the same texture-changing quality–but it was never reported before.

The frogs are found at Reserva Las Gralarias, a nature reserve originally created to protect endangered birds in the Parish of Mindo, in north-central Ecuador.

The researchers, Katherine and Tim Krynak, and colleagues from Universidad Indoamérica and Tropical Herping (Ecuador) co-authored a manuscript describing the new animal and skin texture plasticity in the Zoological Journal of the Linnean Society this week. They believe their findings have broad implications for how species are and have been identified. The process may now require photographs and longer observations in the field to ensure the one species is not mistakenly perceived as two because at least two species of rain frogs can change their appearance.

Katherine Krynak believes the ability to change skin texture to reflect its surroundings may enable P. mutabilis to help camouflage itself from birds and other predators.

The Krynaks originally spotted the small, spiny frog, nearly the width of a marble, sitting on a moss-covered leaf about a yard off the ground on a misty July night in 2009. The Krynaks had never seen this animal before, though Tim had surveyed animals on annual trips to Las Gralarias since 2001, and Katherine since 2005.

They captured the little frog and tucked it into a cup with a lid before resuming their nightly search for wildlife. They nicknamed it “punk rocker” because of the thorn-like spines covering its body.

The next day, Katherine Krynak pulled the frog from the cup and set it on a smooth white sheet of plastic for Tim to photograph. It wasn’t “punk “–it was smooth-skinned. They assumed that, much to her dismay, she must have picked up the wrong frog.

“I then put the frog back in the cup and added some moss,” she said. “The spines came back… we simply couldn’t believe our eyes, our frog changed skin texture!

“I put the frog back on the smooth white background. Its skin became smooth.”

“The spines and coloration help them blend into mossy habitats, making it hard for us to see them,” she said. “But whether the texture really helps them elude predators still needs to be tested.”

During the next three years, a team of fellow biologists studied the frogs. They found the animals shift skin texture in a little more than three minutes.

Juan M. Guayasamin, from Universidad Tecnológica Indoamérica, Ecuador, the manuscript’s first author, performed morphological and genetic analyses showing that P. mutabilis was a unique and undescribed species. Carl R. Hutter, from the University of Kansas, studied the frog’s calls, finding three songs the species uses, which differentiate them from relatives. The fifth author of the paper, Jamie Culebras, assisted with fieldwork and was able to locate a second population of the species. Culebras is a member of Tropical Herping, an organization committed to discovering, and studying reptiles and amphibians.

Guayasamin and Hutter discovered that Prismantis sobetes, a relative with similar markings but about twice the size of P. mutabilis, has the same trait when they placed a spiny specimen on a sheet and watched its skin turn smooth. P. sobetes is the only relative that has been tested so far.

Because the appearance of animals has long been one of the keys to identifying them as a certain species, the researchers believe their find challenges the system, particularly for species identified by one or just a few preserved specimens. With those, there was and is no way to know if the appearance is changeable.

The Krynaks, who helped form Las Gralarias Foundation to support the conservation efforts of the reserve, plan to return to continue surveying for mutable rain frogs and to work with fellow researchers to further document their behaviors, lifecycle and texture shifting, and estimate their population, all in effort to improve our knowledge and subsequent ability to conserve this paradigm shifting species.

Further, they hope to discern whether more relatives have the ability to shift skin texture and if that trait comes from a common ancestor. If P. mutabilis and P. sobetes are the only species within this branch of Pristimantis frogs to have this capability, they hope to learn whether they retained it from an ancestor while relatives did not, or whether the trait evolved independently in each species.

Among many of the pressures on frog populations, there’s a lethal fungus which has affected some 200 species of frogs. A March 23, 2015 news item on ScienceDaily describes some recent research into the bacterial communities present on frog skin,

A team of scientists including Virginia Tech researchers is one step closer to understanding how bacteria on a frog’s skin affects its likelihood of contracting disease.

A frog-killing fungus known as Batrachochytrium dendrobatidis, or Bd, has already led to the decline of more than 200 amphibian species including the now extinct-in-the-wild Panamanian golden frog.

In a recent study, the research team attempted to apply beneficial bacteria found on the skin of various Bd-resistant wild Panamanian frog species to Panamanian golden frogs in captivity, to see if this would stimulate a defense against the disease.

A March 23, 2015 Virginia Tech University news release on EurekAlert, which originated the news item, provides a twist and a turn in the story (Note: Links have been removed),

They found that while the treatment with beneficial bacteria was not successful due to its inability to stick to the skin, there were some frogs that survived exposure to the fungus.

These survivors actually had unique bacterial communities on their skin before the experiments started.

The next step is to explore these new bacterial communities.

“We were disappointed that the treatment didn’t work, but glad to have discovered new information about the relationship between these symbiotic microbial communities and amphibian disease resistance,” said Lisa Belden, an associate professor of biological sciences in the College of Science, a Fralin Life Science Institute affiliate, and a faculty member with the new Global Change Center at Virginia Tech. “Every bit of information gets us closer to getting these frogs back into nature.”

Studying the microbial communities of Panamanian golden frogs was the dissertation focus of Belden’s former graduate student Matthew Becker, who graduated with a Ph.D. in biological sciences from Virginia Tech in 2014 and is now a fellow at the Smithsonian Conservation Biology Institute.

“Anything that can help us predict resistance to this disease is very useful because the ultimate goal of this research is to establish healthy populations of golden frogs in their native habitat,” Becker told Smithsonian Science News. “I think identifying alternative probiotic treatment methods that optimize dosages and exposure times will be key for moving forward with the use of probiotics to mitigate chytridiomycosis.”

Université de Montréal (Canada) and nanobots breech blood-brain barrier to deliver drugs to the brain

In the spirit of full disclosure, the March 25, 2014 news item on ScienceDaily describing the research about breeching the blood-brain barrier uses the term nanorobotic agents rather than nanobots, a term which makes my headline a lot catchier although less accurate. Getting back to the research,

Magnetic nanoparticles can open the blood-brain barrier and deliver molecules directly to the brain, say researchers from the University of Montreal, Polytechnique Montréal, and CHU Sainte-Justine. This barrier runs inside almost all vessels in the brain and protects it from elements circulating in the blood that may be toxic to the brain. The research is important as currently 98% of therapeutic molecules are also unable to cross the blood-brain barrier.

“The barrier is temporary [sic] opened at a desired location for approximately 2 hours by a small elevation of the temperature generated by the nanoparticles when exposed to a radio-frequency field,” explained first author and co-inventor Seyed Nasrollah Tabatabaei. “Our tests revealed that this technique is not associated with any inflammation of the brain. This new result could lead to a breakthrough in the way nanoparticles are used in the treatment and diagnosis of brain diseases,” explained the co-investigator, Hélène Girouard. “At the present time, surgery is the only way to treat patients with brain disorders. Moreover, while surgeons are able to operate to remove certain kinds of tumors, some disorders are located in the brain stem, amongst nerves, making surgery impossible,” added collaborator and senior author Anne-Sophie Carret.

A March 25, 2015 University of Montreal news release (also on EurekAlert), which originated the news item, notes that the technique was tested or rats or mice (murine model) and explains how the technology breeches the blood-brain barrier,

Although the technology was developed using murine models and has not yet been tested in humans, the researchers are confident that future research will enable its use in people. “Building on earlier findings and drawing on the global effort of an interdisciplinary team of researchers, this technology proposes a modern version of the vision described almost 40 years ago in the movie Fantastic Voyage, where a miniature submarine navigated in the vascular network to reach a specific region of the brain,” said principal investigator Sylvain Martel. In earlier research, Martel and his team had managed to manipulate the movement of nanoparticles through the body using the magnetic forces generated by magnetic resonance imaging (MRI) machines.

To open the blood-brain barrier, the magnetic nanoparticles are sent to the surface of the blood-brain barrier at a desired location in the brain. Although it was not the technique used in this study, the placement could be achieved by using the MRI technology described above. Then, the researchers generated a radio-frequency field. The nanoparticles reacted to the radio-frequency field by dissipating heat thereby creating a mechanical stress on the barrier. This allows a temporary and localized opening of the barrier for diffusion of therapeutics into the brain.

The technique is unique in many ways. “The result is quite significant since we showed in previous experiments that the same nanoparticles can also be used to navigate therapeutic agents in the vascular network using a clinical MRI scanner,” Martel remarked. “Linking the navigation capability with these new results would allow therapeutics to be delivered directly to a specific site of the brain, potentially improving significantly the efficacy of the treatment while avoiding systemic circulation of toxic agents that affect healthy tissues and organs,” Carret added. “While other techniques have been developed for delivering drugs to the blood-brain barrier, they either open it too wide, exposing the brain to great risks, or they are not precise enough, leading to scattering of the drugs and possible unwanted side effect,” Martel said.

Although there are many hurdles to overcome before the technology can be used to treat humans, the research team is optimistic. “Although our current results are only proof of concept, we are on the way to achieving our goal of developing a local drug delivery mechanism that will be able to treat oncologic, psychiatric, neurological and neurodegenerative disorders, amongst others,” Carret concluded.

More about MUSE, a Canadian company and its brain sensing headband; women and startups; Canadianess

I first wrote about Ariel Garten and her Toronto-based (Canada) company, InteraXon, in a Dec. 5, 2012 posting where I featured a product, MUSE (Muse), then described as a brainwave controller. A March 5, 2015 article by Lydia Dishman for Fast Company provides an update on the product now described as a brainwave-sensing headband and on the company (Note: Links have been removed),

The technology that had captured the imagination of millions was then incorporated to develop a headband called Muse. It sells at retail stores like BestBuy for about $300 and works in conjunction with an app called Calm as a tool to increase focus and reduce stress.

If you always wanted to learn to meditate without those pesky distracting thoughts commandeering your mind, Muse can help by taking you through a brief exercise that translates brainwaves into the sound of wind. Losing focus or getting antsy brings on the gales. Achieving calm rewards you with a flock of birds across your screen.

The company has grown to 50 employees and has raised close to $10 million from investors including Ashton Kutcher. Garten [Ariel Garten, founder and Chief Executive Founder] says they’re about to close on a Series B round, “which will be significant.”

She says that listening plays an important role at InteraXon. Reflecting back on what you think you heard is an exercise she encourages, especially in meetings. When the development team is building a tool, for example, they use their Muses to meditate and focus, which then allows for listening more attentively and nonjudgmentally.

Women and startups

Dishman references gender and high tech financing in her article about Garten,

Garten doesn’t dwell on her status as a woman in a mostly male-dominated sector. That goes for securing funding for the startup too, despite the notorious bias venture-capital investors have against women startup founders.

“I am sure I lost deals because I am a woman, but also because the idea didn’t resonate,” she says, adding, “I’m sure I gained some because I am a woman, so it is unfair to put a blanket statement on it.”

Yet Garten is the only female member of her C-suite, something she says “is just the way it happened.” Casting the net recently to fill the role of chief operating officer [COO], Garten says there weren’t any women in the running, in part because the position required hardware experience as well as knowledge of working with the Chinese.

She did just hire a woman to be senior vice president of sales and marketing, and says, “When we are hiring younger staff, we are gender agnostic.”

I can understand wanting to introduce nuance into the ‘gender bias and tech startup discussion’ by noting that some rejections could have been due to issues with the idea or implementation. But the comment about being the only female in late stage funding as “just the way it happened” suggests she is extraordinarily naïve or willfully blind. Given her followup statement about her hiring practices, I’m inclined to go with willfully blind. It’s hard to believe she couldn’t find any woman with hardware experience and China experience. It seems more likely she needed a male COO to counterbalance a company with a female CEO. As for being gender agnostic where younger staff are concerned, that’s nice but it’s not reassuring as women have been able to get more junior positions. It’s the senior positions such as COO which remain out of reach and, troublingly, Garten seems to have blown off the question with a weak explanation and a glib assurance of equality at the lower levels of the company.

For more about gender, high tech companies, and hiring/promoting practices, you can read a March 5, 2015 article titled, Ellen Pao Trial Reveals the Subtle Sexism of Silicon Valley, by Amanda Marcotte for Slate.

Getting back to MUSE, you can find out more here. You can find out more about InterAxon here. Unusually, there doesn’t seem to be any information about the management team on the website.

Canadianness

I thought it was interesting that InterAxon’s status as a Canada-based company was mentioned nowhere in Dishman’s article. This is in stark contrast to Nancy Owano’s  Dec. 5, 2012 article for phys.org,

A Canadian company is talking about having a window, aka computer screen, into your mind. … InteraXon, a Canadian company, is focused on making a business out of mind-control technology via a headband device, and they are planning to launch this as a $199 brainwave computer controller called Muse. … [emphases mine]

This is not the only recent instance I’ve noticed. My Sept. 1, 2014 posting mentions what was then an upcoming Margaret Atwood event at Arizona State University,

… (from the center’s home page [Note: The center is ASU’s Center for Science and the Imagination]),

Internationally renowned novelist and environmental activist Margaret Atwood will visit Arizona State University this November [2014] to discuss the relationship between art and science, and the importance of creative writing and imagination for addressing social and environmental challenges.

Atwood’s visit will mark the launch of the Imagination and Climate Futures Initiative … Atwood, author of the MaddAddam trilogy of novels that have become central to the emerging literary genre of climate fiction, or “CliFi,” will offer the inaugural lecture for the initiative on Nov. 5.

“We are proud to welcome Margaret Atwood, one of the world’s most celebrated living writers, to ASU and engage her in these discussions around climate, science and creative writing,” …  “A poet, novelist, literary critic and essayist, Ms. Atwood epitomizes the creative and professional excellence our students aspire to achieve.”

There’s not a single mention that she is Canadian there or in a recent posting by Martin Robbins about a word purge from the Oxford Junior Dictionary published by the Guardian science blog network (March 3, 2015 posting). In fact, Atwood was initially described by Robbins as one of Britain’s literary giants. I assume there were howls of anguish once Canadians woke up to read the article since the phrase was later amended to “a number of the Anglosphere’s literary giants.”

The omission of InterAxon’s Canadianness in Dishman’s article for an American online magazine and Atwood’s Canadianness on the Arizona State University website and Martin Robbins’ initial appropriation and later change to the vague-sounding “Anglospere” in his post for the British newspaper, The Guardian, means the bulk of their readers will likely assume InterAxon is American and that Margaret Atwood, depending on where you read about her, is either an American or a Brit.

It’s flattering that others want to grab a little bit of Canada for themselves.

Coda: The Oxford Junior Dictionary and its excision of ‘nature’ words

 

Robbins’ March 3, 2015 posting focused on a heated literary discussion about the excision of these words from the Oxford Junior Dictionary (Note:  A link has been removed),

“The deletions,” according to Robert Macfarlane in another article on Friday, “included acorn, adder, ash, beech, bluebell, buttercup, catkin, conker, cowslip, cygnet, dandelion, fern, hazel, heather, heron, ivy, kingfisher, lark, mistletoe, nectar, newt, otter, pasture and willow. The words taking their places in the new edition included attachment, block-graph, blog, broadband, bullet-point, celebrity, chatroom, committee, cut-and-paste, MP3 player and voice-mail.”

I’m surprised the ‘junior’ dictionary didn’t have “attachment,” “celebrity,” and “committee” prior to the 2007 purge. By the way, it seems no one noticed the purge till recently. Robbins has an interesting take on the issue, one with which I do not entirely agree. I understand needing to purge words but what happens a child reading a classic such as “The Wind in the Willows’ attempts to look up the word ‘willows’?  (Thanks to Susan Baxter who in a private communication pointed out the problems inherent with reading new and/or classic books and not being able to find basic vocabulary.)

Hydro-Québec, lithium-ion batteries, and silicate-based nanoboxes

Hydro-Québec (Canada) is making a bit of a splash these days (this is the third mention within less than a week) on my blog, if nowhere else. The latest development was announced in a Feb. 24, 2015 news item on Nanowerk (Note: A link has been removed),

Researchers from Singapore’s Institute of Bioengineering and Nanotechnology (IBN) of A*STAR and Quebec’s IREQ (Hydro-Québec’s research institute) have synthesized silicate-based nanoboxes that could more than double the energy capacity of lithium-ion batteries as compared to conventional phosphate-based cathodes (“Synthesis of Phase-Pure Li2MnSiO4@C Porous Nanoboxes for High-Capacity Li-Ion Battery Cathodes”). This breakthrough could hold the key to longer-lasting rechargeable batteries for electric vehicles and mobile devices.

A Feb. 24, 2015 Hydro-Québec press release (also on Canadian News Wire), which originated the news item, describe the research and the relationship between the two institutions,

“IBN researchers have successfully achieved simultaneous control of the phase purity and nanostructure of Li2MnSiO4 for the first time,” said Professor Jackie Y. Ying, IBN Executive Director. “This novel synthetic approach would allow us to move closer to attaining the ultrahigh theoretical capacity of silicate-based cathodes for battery applications.”

“We are delighted to collaborate with IBN on this project. IBN’s expertise in synthetic chemistry and nanotechnology allows us to explore new synthetic approaches and nanostructure design to achieve complex materials that pave the way for breakthroughs in battery technology, especially regarding transportation electrification,” said Dr. Karim Zaghib, Director – Energy Storage and Conservation at Hydro-Québec.

Lithium-ion batteries are widely used to power many electronic devices, including smart phones, medical devices and electric vehicles. Their high energy density, excellent durability and lightness make them a popular choice for energy storage. Due to a growing demand for long-lasting, rechargeable lithium-ion batteries for various applications, significant efforts have been devoted to improving the capacity of these batteries. In particular, there is great interest in developing new compounds that may increase energy storage capacity, stability and lifespan compared to conventional lithium phosphate batteries.

The five-year research collaboration between IBN and Hydro-Québec was established in 2011. The researchers plan to further enhance their new cathode materials to create high-capacity lithium-ion batteries for commercialization.

McGill University (Canada) researchers build DNA nanotubes block by block

McGill University (Montréal, Québec, Canada) researchers have found a new technique for creating DNA (deoxyribonucleic acid) nanotubes according to a Feb. 24, 2015 news item on Azonano,

Researchers at McGill University have developed a new, low-cost method to build DNA nanotubes block by block – a breakthrough that could help pave the way for scaffolds made from DNA strands to be used in applications such as optical and electronic devices or smart drug-delivery systems.

A Feb. 23, 2015 McGill University news release (also on EurekAlert), which originated the news item, describes current practice and the new technique,

Many researchers, including the McGill team, have previously constructed nanotubes using a method that relies on spontaneous assembly of DNA in solution. The new technique, reported today in Nature Chemistry, promises to yield fewer structural flaws than the spontaneous-assembly method. The building-block approach also makes it possible to better control the size and patterns of the DNA structures, the scientists report.

“Just like a Tetris game, where we manipulate the game pieces with the aim of creating a horizontal line of several blocks, we can now build long nanotubes block by block,” said Amani Hariri, a PhD student in McGill’s Department of Chemistry and lead author of the study. “By using a fluorescence microscope we can further visualize the formation of the tubes at each stage of assembly, as each block is tagged with a fluorescent compound that serves as a beacon. We can then count the number of blocks incorporated in each tube as it is constructed.”

This new technique was made possible by the development in recent years of single-molecule microscopy, which enables scientists to peer into the nano-world by turning the fluorescence of individual molecules on and off. (That groundbreaking work won three U.S.- and German-based scientists the 2014 Nobel Prize in Chemistry.)

Hariri’s research is jointly supervised by chemistry professors Gonzalo Cosa and Hanadi Sleiman, who co-authored the new study. Cosa’s research group specializes in single-molecule fluorescence techniques, while Sleiman’s uses DNA chemistry to design new materials for drug delivery and diagnostic tools.

The custom-built assembly technique developed through this collaboration “gives us the ability to monitor the nanotubes as we’re building them, and see their structure, robustness and morphology,” Cosa said.

“We wanted to control the nanotubes’ lengths and features one-by-one,” said Sleiman, who holds the Canada Research Chair in DNA Nanoscience. The resulting “designer nanotubes,” she adds, promise to be far cheaper to produce on a large scale than those created with so-called DNA origami, another innovative technique for using DNA as a nanoscale construction material.

This is outside my usual range of topics but given water’s importance in our survival I am inclined to feature this new UN (United Nations) report on water. From a Feb. 22, 2015 UN University (UNU) Institute for Water, Environment and Health (INWEH) news release on EurekAlert,

A new UN report warns that without large new water-related investments many societies worldwide will soon confront rising desperation and conflicts over life’s most essential resource.

The news release describes the situation,

Continued stalling, coupled with population growth, economic instability, disrupted climate patterns and other variables, could reverse hard-earned development gains and preclude meaningful levels of development that can be sustained into the future.

Says lead author Bob Sandford, EPCOR Chair, Canadian Partnership Initiative in support of the UN Water for Life Decade: “The consequence of unmet water goals will be widespread insecurity creating more international tension and conflict. The positive message is that if we can keep moving now on water-related Sustainable Development Goals we can still have the future we want.”

Published in the run-up to the adoption this September of universal post-2015 Sustainable Development Goals (SDGs), the report provides an in-depth analysis of 10 countries to show how achieving water and sanitation-related SDGs offers a rapid, cost effective way to achieve sustainable development.

The 10 countries given the analysis are not the ‘usual suspects’ (from the news release),

The countries included in the study cover the full range of economic and development spectrum: Bangladesh, Bolivia, Canada, Indonesia, Republic of Korea, Pakistan, Singapore, Uganda, Vietnam, and Zambia.

Based on the national case studies, the report prescribes country level steps for achieving the global water targets.

No US. No China. No Middle Eastern countries. No Australia. No India. No Japan. No European countries. There is one North American country, two African countries and one South American country in addition to the Asian countries. To my knowledge none of the included countries is strongly associated with desert regions.

It’s an interesting set of choices and the report offers no explanation as to why these 10 countries rather than 10 others. You can check if for yourself on p. 29 (the introductory first page of Part Three: Learning from National Priorities and Strategies) of the 2015 Water in the World We Want report.

Water scarcity hurts everybody

Moving on to the report’s recommendations as noted in the news release,

Among top recommendations: Hold the agriculture sector (which guzzles roughly 70% of world water supplies), and the energy sector (15%), accountable for making efficiencies while transitioning to clean energy including hydropower.

Prepared in association with the Global Water Partnership and Canada’s McMaster University, the report says the success of global efforts on the scale required rests in large part on a crackdown on widespread corruption in the water sector, particularly in developing countries.

“In many places … corruption is resulting in the hemorrhaging of precious financial resources,” siphoning an estimated 30% of funds earmarked for water and sanitation-related improvements.

The report underscores the need for clearly defined anti-corruption protocols enforced with harsh penalties.

Given accelerating Earth system changes and the growing threat of hydro-climatic disruption, corruption undermining water-related improvements threatens the stability and very existence of some nation states, which in turn affects all other countries, the report says.

“Corruption at any level is not just a criminal act in its own right. In the context of sustainable development it could be viewed as a crime against all of humanity.”

The report notes that the world’s water and wastewater infrastructure maintenance and replacement deficit is building at a rate of $200 million per year, with $1 trillion now required in the USA alone.

To finance its recommendations, the report says that, in addition to plugging the leakage of funds to corruption, $1.9 trillion in subsidies to petroleum, coal and gas industries should be redirected by degrees.

The estimated global cost to achieve post-2015 sustainable development goals in water and sanitation development, maintenance and replacement is US $1.25 trillion to $2.25 trillion per year for 20 years, a doubling or tripling of current spending translating into 1.8 to 2.5 percent of global GDP.

The resulting benefits would be commensurately large, however – a minimum of $3.11 trillion per year, not counting health care savings and valuable ecosystem service enhancements.

Changes in fundamental hydrology “likely to cause new kinds of conflict”

Sandford and co-lead author Corinne J. Schuster-Wallace of UNU-INWEH underline that all current water management challenges will be compounded one way or another by climate change, and by increasingly unpredictable weather.

“Historical predictability, known as relative hydrological stationarity … provides the certainty needed to build houses to withstand winds of a certain speed, snow of a certain weight, and rainfalls of certain intensity and duration, when to plant crops, and to what size to build storm sewers. The consequence is that the management of water in all its forms in the future will involve a great deal more uncertainty than it has in the past.”

“In a more or less stable hydro-climatic regime you are playing poker with a deck you know and can bet on risk accordingly. The loss of stationarity is playing poker with a deck in which new cards you have never seen before keep appearing more and more often, ultimately disrupting your hand to such an extent that the game no longer has coherence or meaning.”

“People do not have the luxury of living without water and when faced with a life or death decision, people tend to do whatever they must to survive … Changes in fundamental hydrology are likely to cause new kinds of conflict, and it can be expected that both water scarcity and flooding will become major trans-boundary water issues.”

Within 10 years, researchers predict 48 countries – 25% of all nations on Earth with an expected combined population of 2.9 billion – will be classified “water-scarce” (1,000 to 1,700 cubic meters of water per capita per year) or “water-stressed” (1,000 cubic meters or less). [emphases mine]

And by 2030, expect overall global demand for freshwater to exceed supply by 40%, with the most acute problems in warmer, low-resource nations with young, fast-growing populations, according to the report. [emphasis mine]

An estimated 25% of the world’s major river basins run dry for part of each year, the report notes, and “new conflicts are likely to emerge as more of the world’s rivers become further heavily abstracted so that they no longer make it to the sea.”

Meanwhile, the magnitude of floods in Pakistan and Australia in 2010, and on the Great Plains of North America in 2011 and 2014, “suggests that the destruction of upstream flood protection and the failure to provide adequate downstream flood warning will enter into global conflict formulae in the future.”

The report cites the rising cost of world flood-related damages: US$53 billion in 2013 and more than US$312 billion since 2004.

Included in the global flood figures: roughly $1 billion in flood damage in the Canadian province of Manitoba in both 2011 and 2014. The disasters have affected the province’s economic and political stability, contributing to a budget deficit, an unpopular increase in the provincial sales tax and to the consequent resignation of political leaders. [emphases mine]

UNU-INWEH Director Zafar Adeel and Jong Soo Yoon, Head of the UN Office for Sustainable Development, state: “Through a series of country case studies, expert opinion, and evidence synthesis, the report explores the critical role that water plays (including sanitation and wastewater management) in sustainable development; current disconnects between some national development plans and the proposed SDGs; opportunities for achieving sustainable development through careful water management; and implementation opportunities.”

The report, they add, “fills a critical gap in understanding the complexities associated with water resources and their management, and also provides substantive options that enable us to move forward within the global dialogue.”

Juxtaposing the situation in Manitoba with the situation in warmer, low-resource nations emphasizes the universality of the problem. Canadians can be complacent about water scarcity, especially where I live in the Pacific Northwest, but it affects us all.

Corruption bites everywhere

As for the corruption mentioned in the news release and report, while there is no news of ‘water’ corruption here, the country does have its own track record with regard to financial boondoggles. For example, the Auditor-General reported in 2013 that $3.1B spent on measures to combat terrorism was unaccounted for (from an April 30, 2013 Globe & Mail article by Gloria Galloway and Daniel Leblanc),

The federal government cannot account for billions of dollars that were devoted to combatting terrorism after the Sept. 11 [2001] attacks, Canada’s Auditor-General says in a new report.

Between 2001 and 2009, Ottawa awarded $12.9-billion to 35 departments and agencies charged with ensuring the safety of Canadians to use for public security and fighting terrorism. The money allocated through the Public Security and Anti-Terrorism Initiative was intended to pay for measures designed to keep terrorists out of Canada, to prosecute those found in the country, to support international initiatives, and to protect infrastructure.

But Auditor-General Michael Ferguson said only $9.8-billion of that money was identified in reports to the Treasury Board as having been spent specifically on anti-terrorism measures by the departments and agencies. The rest was not recorded as being used for that purpose. Some was moved to other priorities, and some lapsed without being spent, but the government has no full breakdown for the $3.1-billion.

The time period 2001 – 2009 implicates both Liberal and Conservative governments, the Conservatives having come to power in 2006.

About Bob Sandford and EPCOR

One final note, the report’s co-lead author, Bob Sandford, is described as the chair for EPCOR Canadian Partnership Initiative in support of the UN Water for Life Decade, It’s a rather interesting title in that Sandford is not on the EPCOR board. Here’s how EPCOR describes Sandford on the company’s webpage dedicated to him and dated March 13, 2013,

Robert Sandford is the EPCOR Chair in support of the United Nations “Water for Life” Decade of Action initiative in Canada. We support his efforts as he speaks in plain language to policy makers, explaining how his work links research and analysis to public policy ideas that help protect water supplies and reduce water consumption.

We’re proud to sponsor his leadership efforts to educate Canadians and help local and international governments become better stewards of a most precious resource. Supporting Robert is just one of the ways EPCOR works to protect water in our communities.

The company which is owned solely by the city of Edmonton (Alberta) was originally named Edmonton Electric Lighting and Power Company in 1891. As they say on the company’s About page, “We provide electricity and water services to customers in Canada and the US.” They also develop some nice public relations strategies. I’m referring, of course, to the Sandford sponsorship which can be better appreciated by going to Sandford’s, from the homepage,

Bob Sandford is the EPCOR Chair of the Canadian Partnership Initiative in support of United Nations “Water for Life” Decade. This national partnership initiative aims to inform the public on water issues and translate scientific research outcomes into language decision-makers can use to craft timely and meaningful public policy.

Bob is also the Director of the Western Watersheds Research Collaborative and an associate of the Centre for Hydrology which is part of the Global Water Institute at the University of Saskatchewan. Bob is also a Fellow of the Biogeoscience Institute at the University of Calgary. He sits on the Advisory Board of Living Lakes Canada, the Canadian Chapter of Living Lakes International and is also a member of the Forum for Leadership on Water (FLOW), a national water policy research group centred in Toronto. Bob also serves as Water Governance Adviser and Senior Policy Author for Simon Fraser University’s Adaptation to Climate Change Team. In 2011, Bob was invited to be an advisor on water issues by the Interaction Council, a global public policy forum composed of more than thirty former Heads of State including Canadian Prime Minister Jean Chretien, U.S. President Bill Clinton, and the former Prime Minister of Norway, Gro Brundtland. In this capacity Bob works to bring broad international example to bear on Canadian water issues. In 2013, Alberta Ventures magazine recognized Bob as one of the year’s 50 most influential Albertans.

I guess Mr. Sandford knows his water.

NanoXplore: graphene and graphite in Québec (Canada)

For the second time this week I’m going to be mentioning the province of Québec (Canada) in relation to its ‘nanotechnology’ businesses (see: Cellulose nanocrystals (CNC), also known as nanocrystalline cellulose (NCC), and toxicity; some Celluforce news; anti-petroleum extremists posted on Feb. 19, 2015). A Feb. 20, 2015 news item on Azonano announces a graphene production facility in the Montréal area,

Group NanoXplore Inc., a Montreal-based company specialising in the production and application of graphene and its derivative materials, announced today that its graphene production facility is in full operation with a capacity of 3 metric tonnes per year. This is the largest graphene production capacity in Canada and, outside of China, one of the 5 largest in the world.

A Feb. 19, 2015 NanoXplore news release on MarketWire, which originated the news item, provides a bit more detail in amidst the promotional hype,

NanoXplore’s production process is unique and the core of the company’s competitive advantage. The proprietary process gently and efficiently creates pristine graphene from natural flake graphite without creating the crystalline defects that can limit performance. The process also functionalises the graphene material during production making subsequent mixing with a broad range of industrial materials simple and efficient. NanoXplore’s facility is routinely producing several standard grades of graphene as well as derivative products such as a unique graphite-graphene composite suitable for anodes in Li-ion batteries. [emphasis mine]

Another graphite connection in Québec

Interestingly, back in 2012 Hydro-Québec signed a deal with another Québec-based company, Focus Graphite (which owns a graphite deposit in the northeastern part of the province) to explore ways to produce more efficient lithium-ion batteries (my Nov 27, 2012 posting).

Getting back to the news release, it also provides a summary description of NanoXplore,

NanoXplore is a privately held advanced materials company focused on the large-scale production of high quality graphene and the integration of graphene into real world industrial products. NanoXplore achieves significant improvements in performance for its customers with very low levels of graphene because its material is of high quality (few defects, highly dispersible), because the production process can easily tune the dimensions of the graphene platelets, and because NanoXplore has specific expertise in dispersing graphene in a broad range of industrial materials. NanoXplore partners with its customers to integrate graphene into their products and processes, providing them with innovative products and a strong competitive advantage.

Graphite mines

NanoXplore, too, has some sort of relationship with a graphite mine or, in this case mining company, Mason Graphite (from the NanoXplore website’s Investors’ page),

FROM MINE TO PRODUCT

Partnered with Canadian mining company Mason Graphite, NanoXplore has access to lower quartile graphite/graphene production costs as well as a stable, long term, large flake source of raw material. Local government bodies have embraced the graphite-graphene cluster. With production and R&D centrally located in Montreal, NanoXplore offers world class innovation and true intellectual property safety for its formulation partners.

By the way, Benoit Gascon, NanoXplore’s board chair (scroll down to the bottom  of the team list) is also Mason Graphite’s Chief Executive Officer (CEO). The company has recently announced a detailed study on large-scale production of value-added graphite products (from a Feb. 11, 2015 Mason Graphite news release),

Mason Graphite Inc. (“Mason Graphite” or the “Company”) (TSX VENTURE:LLG)(OTCQX:MGPHF) announces that it has initiated a detailed study for large scale processing of value-added graphite products.

Value-added processing includes micronization, additional purification, spheronization and coating, resulting in graphite products that are suitable for a wide range of electrochemical applications (including alkaline batteries, lithium-ion batteries and fuel cells), technical applications (including carbon brushes, brake linings, plastics and lubricants), and other specialized uses.

The development and validation of the fabrication processes for these graphite products will be carried out by the National Research Council of Canada (“NRC”) along with Hatch, and is expected to conclude by the end of 2015. Following initial scoping work, equipment trials and product testing, the Company intends to provide preliminary results and an updated work program by mid-2015.

The NRC is the Government of Canada’s premier research and technology organization. Hatch is an engineering firm located in Montreal which is already working closely with Mason Graphite on the development of the Lac Gueret Graphite Project.

Other parts of Canada and the graphite/graphene enterprise

NanoXplore and Focus Graphite are not the only companies with connections to a graphite mine in Québec. There’s also Vancouver (Canada)-based Lomiko Metals (mentioned here in an April 17, 2013 posting [for the first time]. A. Paul Gill, Lomiko’s CEO, seems to be pursuing a similar business strategy in that Lomiko, too, has a number of business alliances, e.g., the mine, a research and development laboratory, etc. Moving out of Québec, there is also a graphite mine in Ontario owned by Northern Graphite (my Feb. 6, 2012 posting). It seems Canadians in eastern Canada have a valuable resource in graphite flakes.

Cellulose nanocrystals (CNC), also known as nanocrystalline cellulose (NCC), and toxicity; some Celluforce news; anti-petroleum extremists

The February 2015 issue of Industrial Biotechnology is hosting a special in depth research section on the topic of cellulose nanotechnology. A Feb. 19, 2015 news item on Phys.org features a specific article in the special section (Note: A link has been removed),

Novel nanomaterials derived from cellulose have many promising industrial applications, are biobased and biodegradable, and can be produced at relatively low cost. Their potential toxicity—whether ingested, inhaled, on contact with the skin, or on exposure to cells within the body—is a topic of intense discussion, and the latest evidence and insights on cellulose nanocrystal toxicity are presented in a Review article in Industrial Biotechnology.

Maren Roman, PhD, Virginia Tech, Blacksburg, VA, describes the preparation of cellulose nanocrystals (CNCs) and highlights the key factors that are an essential part of studies to assess the potential adverse health effects of CNCs by various types of exposure. In the article “Toxicity of Cellulose Nanocrystals: A Review” , Dr. Roman discusses the current literature on the pulmonary, oral, dermal, and cytotoxicity of CNCs, provides an in-depth view on their effects on human health, and suggests areas for future research.

There has been much Canadian investment both federal and provincial in cellulose nanocrystals (CNC). There’s also been a fair degree of confusion regarding the name. In Canada, which was a research leader initially, it was called nanocrystalline cellulose (NCC) but over time a new term was coined cellulose nanocrystals (CNC). The new name was more in keeping with the naming conventions for other nanoscale cellulose materials such as  cellulose nanofibrils, etc. Hopefully, this confusion will resolve itself now that Celluforce, a Canadian company, has trademarked NCC. (More about Celluforce later in this post.)

Getting back to toxicity and CNC, here’s a link to and a citation for Maron’s research paper,

Toxicity of Cellulose Nanocrystals: A Review by Roman Maren. Industrial Biotechnology. February 2015, 11(1): 25-33. doi:10.1089/ind.2014.0024.

The article is open access at this time. For anyone who doesn’t have the time to read it, here’s the conclusion,

Current studies of the oral and dermal toxicity of CNCs have shown a lack of adverse health effects. The available studies, however, are still very limited in number (two oral toxicity studies and three dermal toxicity studies) and in the variety of tested CNC materials (CelluForce’s NCC). Additional oral and dermal toxicity studies are needed to support the general conclusion that CNCs are nontoxic upon ingestion or contact with the skin. Studies of pulmonary and cytotoxicity, on the other hand, have yielded discordant results. The questions of whether CNCs have adverse health effects on inhalation and whether they elicit inflammatory or oxidative stress responses at the cellular level therefore warrant further investigation. The toxicity of CNCs will depend strongly on their physicochemical properties—in particular, surface chemistry, including particle charge, and degree of aggregation, which determines particle shape and dimensions. Therefore, these properties—which in turn depend strongly on the cellulose source, CNC preparation procedure, and post-processing or sample preparation methods, such as lyophilization, aerosolization, sonication, or sterilization—need to be carefully measured in the final samples.

Another factor that might affect the outcomes of toxicity studies are sample contaminants, such as endotoxins or toxic chemical impurities. Samples for exposure tests should therefore be carefully analyzed for such contaminants prior to testing. Ideally, because detection of toxic chemical contaminants may be difficult, control experiments should be carried out with suitable blanks from which the CNCs have been removed, for example by membrane filtration. Moreover, especially in cytotoxicity assessments, the effect of CNCs on pH and their aggregation in the cell culture medium need to be monitored. Only by careful particle characterization and exclusion of interfering factors will we be able to develop a detailed understanding of the potential adverse health effects of CNCs.

If I understand this rightly, CNC seems safe (more or less) when ingested orally (food/drink) or applied to the skin (dermal application) but inhalation seems problematic and there are indications that this could lead to inflammation of lung cells. Other conclusions suggest both the source for the cellulose and CNC preparation may affect its toxicity. I encourage you to read the whole research paper as this author provides good explanations of the terms and summaries of previous research, as well as, some very well considered research.

Here’s more about Industrial Biotechnology’s special research section in the February 2015 issue, from a Feb. 19, 2015 Mary Ann Liebert publishers press release (also on EurekAlert*),

The article is part of an IB IN DEPTH special research section entitled “Cellulose Nanotechnology: Fundamentals and Applications,” led by Guest Editors Jose Moran-Mirabal, PhD and Emily Cranston, PhD, McMaster University, Hamilton, Canada. In addition to the Review article by Dr. Roman, the issue includes Reviews by M. Rose, M. Babi, and J. Moran-Mirabal (“The Study of Cellulose Structure and Depolymerization Through Single-Molecule Methods”) and by X.F. Zhao and W.T. Winter (“Cellulose/cellulose-based nanospheres: Perspectives and prospective”); Original Research articles by A. Rivkin, T. Abitbol, Y. Nevo, et al. (“Bionanocomposite films from resilin-CBD bound to cellulose nanocrystals), and P. Criado, C. Fraschini, S. Salmieri, et al. (“Evaluation of antioxidant cellulose nanocrystals and applications in gellan gum films”); and the Overview article “Cellulose Nanotechnology on the Rise,” by Drs. Moran-Mirabal and Cranston.

Meanwhile Celluforce announces a $4M ‘contribution’ from Sustainable Development Technology Canada (SDTC), from a Feb. 16, 2015 Celluforce news release,

CelluForce welcomes the announcement by Sustainable Development Technology Canada (SDTC) of a contribution of $4.0 million to optimize the extraction process of Nanocrystaline Cellulose (NCC) from dry wood pulp and develop applications for its use in the oil and gas sector. The announcement was made in Quebec City today [Feb. 16, 2015] by the Honourable Greg Rickford, Minister of Natural Resources and Minister for the Federal Economic Development Initiative for Northern Ontario.

NCC is a fundamental building block of trees that can be extracted from the forest biomass and has unique properties that offer a wide range of potential applications. Measured in units as small as nanometres, these tiny structures have strength properties comparable to steel and will have uses in a variety of industrial sectors. In particular, NCC is touted as having the potential to significantly advance the oil and gas industry.

Our Government is positioning Canada as a global leader in the clean technology sector by supporting innovative projects aimed at growing our economy while contributing to a cleaner environment,” said the Honourable Greg Rickford, Canada’s Minister of Natural Resources. [emphasis mine] “By developing our resources responsibly, exploring next-generation transportation and advancing clean energy technology, the projects announced today will create jobs and improve innovation opportunities in Quebec and across Canada.”

“World-class research led to the development of this ground breaking extraction process and placed Canada at the leading edge of NCC research”, stated René Goguen, Acting President of CelluForce Inc. “This announcement by SDTC sets the stage for the pre-commercial development of applications that will not only support Canada’s forest sector but also the oil and gas sector, both of which are important drivers of the Canadian economy.”

This project will further improve and optimize the process developed by CelluForce to extract nanocrystalline cellulose (CelluForce NCC™) from dry wood pulp. In addition to improving the extraction process, this project will investigate additional applications for the oil-and-gas industry such as cementing using this renewable forestry resource.

There’s very little information in this news release other than the fact that CelluForce’s $4M doesn’t need to be repaid seeing it’s described as a ‘contribution’ rather than an investment. The difference between a contribution and a grant, which is what these funds used to be called, somewhat mystifies me unless this is a translation issue.

As for the news release content, it is remarkably scant. This $4M will be spent on improving the extraction process and on applications for the oil and gas industry. Neither the improvements nor the possible applications are described. Hopefully, the government has some means of establishing whether or not those funds (sorry, the contribution) were used for the purposes described.

I am glad to see this in this news release, “Our Government is positioning Canada as a global leader in the clean technology sector …” although I’m not sure how it fits with recent attempts to brand environmentalists as part of an ‘anti-petroleum’ movement as described in a Feb. 19, 2015 post by Glyn Moody for Techdirt (Note: A link has been removed),

As Techdirt has been warning for some time, one of the dangers with the flood of “anti-terrorist” laws and powers is that they are easily redirected against other groups for very different purposes. A story in the Globe and Mail provides another chilling reminder of how that works:

The RCMP [Royal Canadian Mounted Police] has labelled the “anti-petroleum” movement as a growing and violent threat to Canada’s security, raising fears among environmentalists that they face increased surveillance, and possibly worse, under the Harper government’s new terrorism legislation.

As the Globe and Mail article makes clear, environmentalists are now being considered as part of an “anti-petroleum” movement. That’s not just some irrelevant rebranding: it means that new legislation supposedly targeting “terrorism” can be applied.

It seems logically incoherent to me that the government wants clean tech while condemning environmentalists. Whether or not you buy climate change science (for the record, I do), you have to admit that we are running out of petroleum. At heart, both the government and the environmentalists have to agree that we need new sources for fuel. It doesn’t make any sense to spend valuable money, time, and resources on pursuing environmentalists.

This business about the ‘anti-petroleum’ movement reminds me of a copyright kerfuffle including James Moore, currently the Minister of Industry, and writer Cory Doctorow. Moore, Minister of Canadian Heritage at the time, at some sort of public event, labeled Doctorow as a ‘radical extremist’ regarding his (Doctorow’s) views on copyright. The comments achieved notoriety when it appeared that Moore and the organizers denied the comments ever took place. The organizers seemed to have edited the offending video and Moore made public denials. You can read more about the incident in my June 25, 2010 post. Here’s an excerpt from the post which may explain why I feel there is a similarity,

… By simultaneously linking individuals who use violence to achieve their ends (the usual application for the term ‘radical extremists’) to individuals who are debating, discussing, and writing commentaries critical of your political aims you render the term into a joke and you minimize the violence associated with it.

Although with ‘anti-petroleum’, it seems they could decide any dissension is a form of violence. It should be noted that in Canada the Ministry of Industry, is tightly coupled with the Ministry of Natural Resources since the Canadian economy has been and continues to be largely resource-based.

For anyone interested in CelluForce and NCC/CNC, here’s a sampling of my previous posts on the topic,

Description:
Applications from post-graduate and doctoral students in the fields of philosophy, philosophy of science and social sciences, history and philosophy of science, science and technology studies, and cognate fields are invited to a five-day summer school in India, made possible by collaborations between institutions and scholars in Canada, India and Southeast Asia. This will be an excellent opportunity for graduate students interested in receiving advanced training in the philosophy of science and science and technology studies, with a focus on scientific objects and their relation to cosmopolitanism.

The paradigm of scientific objects has undergone a major transformation in recent times. Today, scientific objects are not limited to microscopic or major astronomical objects. A new category of objects involves ontological modes of data, grids, simulation, visualization, etc. Such modes of objects are not merely peripheral props or outcomes of scientific endeavour. They actively constitute scientific theorizing, experimentation and instrumentation, and catalyze notions of cosmopolitanism in the digital world. Cosmopolitanism in this context is defined as a model of cultural and political engagement based on multidirectional exchange and contact across borders. A cosmopolitan approach treats science as a contingent, multifaceted and multicultural network of exchange. The summer school will engage with philosophical themes around the nature of new scientific objects and digital cosmopolitanism.

“The event is organized by the Manipal Centre for Philosophy and Humanities (Manipal University) and by the Social Sciences and Humanities Research Council of Canada-funded Cosmopolitanism and the Local in Science and Nature, a three-year project to establish a research network on cosmopolitanism in science with partners in Canada, India, and Southeast Asia. The project closely examines the actual types of negotiations that go into the making of science and its culture within an increasingly globalized landscape.

Program and Faculty:
Each of the days will be split among:
(a) Background sessions led by Arun Bala, Gordon McOuat and Sundar Sarukkai,
(b) Sessions led by other faculty members with recognized expertise in the theme, and
(c) Sessions devoted to student research projects.

There will be plenty of opportunities for interaction and participation. The seminar will be held in English and readings will be circulated in advance. Special events will be organized to complement session content. There also will be opportunities for exploring the incredible richness and diversity of the region.

Selection Criteria:
We seek outstanding graduate students from Canada, India and Southeast Asia. We will prioritize applications from graduate students in disciplines or with experience in philosophy, philosophy of science, social studies, the history and philosophy of science, or science and technology studies.

Location and Accommodations:
The event will be hosted by the Manipal Centre for Philosophy and Humanities in the picturesque ocean-side state of Karnataka in south-western India. Students will be housed in student residences. The space is wheelchair accessible.

Fees:
A registration fee of Rs 1500 for Indian students and $100 CAD for international students will be charged. This fee will include accommodations and some meals.

Financial Coverage:

Students from India:
Travel for India-based students will be covered by the summer school sponsors.

Students from Canada and Southeast Asia:
Pending government funding, travel costs may be defrayed for students from Canada or Southeast Asia. Students should indicate in their applications whether they have access to travel support (confirmed or unconfirmed) from home institutions or funding agencies. This will not affect the selection process. Acceptance letters will include more information on travel support.

The last bit of information for this post concerns the Situating Science research cluster mentioned here many times. Situating Science was a seven-year project funded by the Social Sciences and Humanities Research Council (SSHRC) which has become the Canadian Consortium for Situating Science and Technology (CCSST) and has some sort of a relationship (some of the Situating Science organizers have moved over) to the Cosmopolitanism project. The consortium seems to be a somewhat diminished version of the cluster so you may want to check it out now while some of the information is still current.

Canada’s Green Earth Nano Science expands into the European Union

It’s nice to learn of another Canadian ‘nanotechnology’ company. According to a Feb. 6, 2015 news item on Nanotechnology Now, Toronto-based Green Earth Nano Science has recently received some very good business news,

Green Earth Nano Science has signed an Exclusive Distribution Agreement with CleanShield Denmark to bring GENS NANO and SOLARSTUCCO self-cleaning coatings, and AGRIHIT biodegradable cleaners, organic plant based disinfectants, and sanitizers into Denmark, Sweden, Norway and German markets.

A Feb. 1, 2015 Green Earth Nano Science news release, which originated the news item, describes the deal in more detail,

Green Earth Nano Science, Inc., (GENS) from Toronto, Canada is one of the first of the new class of global companies specializing in investment, commercialization, manufacturing, and distribution of new sustainable green environmental technologies. GENS have recently expanded its marketplace to Denmark, Sweden, Norway and Germany through Danish company CleanShield by signing Exclusive License Distribution Agreement for distribution and application of its Gens Nano & SolarStucco branded self-cleaning, anti-bacterial coatings, and AgriHit branded organic disinfectants & sanitizers, natural bio degradable cleaners, natural foliar fertilizers & plant growth & health enhancers.

CleanShield, a Denmark Company, is a growing corporation with an existing applicator and sales networks with customers in key Denmark industrial and hospitality segments. CleanShield has strong capabilities to develop sales distribution and application networks through their connection and relationships with many local businesses, government, health care and hospitality facilities plus building maintenance companies. Green technology products portfolio offered by Green Earth Nano Science, Inc. focuses on constant improvements through commercialization of path breaking technologies that benefit the environment as well as people. Many industries benefit from GENS natural products and environmental solutions, including farming, food, health care, hospitality, commercial and residential industries.

Miroslaw Chrzaniecki, VP from Green Earth Nano Science, Inc. stated: “We are energized with opportunity to serve and expend in Denmark, Sweden, Norway and German territories. Looking just at Denmark, it is one of the World’s richest countries, home to various types of industries including big agricultural production companies making it an ideal frontier for expansion. To add to this fact, Denmark’s principal exports: machinery, instruments, food products, industrial machinery, chemical products, furniture, pharmaceuticals, and canned ham and pork can all benefit GENS’s Green 3D Shield bio security system that works wonders by utilizing herbal natural cleaning technologies. Local farmers as mentioned by Mr. Chrzaniecki can also take advantage of the revolutionary AgriHit Plant Growth & Health Enhancer, made from plant extracts when applied diluted with water on the plant leafs help plants to fight off diseases, repel small insects, fungi attacks. [emphasis mine] Other products we introduce in Denmark, Sweden, Norway and Germany are our natural cleaners, organic sanitizers; natural self-cleaning and self-sanitizing antibacterial coatings will benefit many businesses and even home clients as well. For example e-coil, salmonella and other potential devastating outbreaks within food manufactures can be prevented or reduced by application of GENS NANO self sanitizing coating. Hotels and office building and homes can be made as allergy free by treating A/C systems and regular use of food safe, long lasting AgriHit organic disinfectants and by using our plant based antibacterial cleaners in daily cleaning routines. I can talk for hours about many different benefits that together with our exclusive license partners we will introduce in Europe.” opines Miroslaw Chrzaniecki, VP of Green Earth Nano Science, Inc.

On the other hand, Mr. Thomas Gregersen Bowmann, Director of CleanShield shares the same enthusiasm and excitement saying “Now by signing Exclusive Territory Licensing agreement with Canadian company Green Earth Nano Science Inc. we are on the forefront of green revolution in Denmark. With a professional team ready to happily serve and offer these green infection control solutions using GENS’s reliable green-products such as SolarStucco, AgriHit and 3D Shield bio security systems can help sustain our loyal clients’ needs to achieve great savings and reducing outbreak problems while protecting the environment. Crews are experienced and well trained and we are very happy to be able to offer green infection control solutions and implement Green 3D Shield bio security system in their facilities. With the introduction of environment friendly, natural products, we will help our clients to achieve great savings for the whole different industries and also reduce problems associated with outbreaks at the same time. We will be implementing an aggressive marketing strategy to explore all business opportunities in Denmark.”

The AgriHit product, the part about “repel small insects, fungi attacks,” reminds me of Vive Crop Protection (another Toronto-based ‘nano’ company) and its product line. I last mentioned that company in a Nov. 21, 2014 post about the expansion of its manufacturing capabilities.

Getting back to the matter at hand, congratulations to Green Earth Nano Science! You can find out more about CleanShield here, provided you have Danish language skills. For anyone particularly interested in AgriHit (the Green Earth Nano Science [GENS] product), it has its own website here. One comment, I found the GENS website organization a little confusing. I advise checking both the Solutions tab and the Products tab if you’re interested in learning more about their products, as well as, visiting the AgriHit website.
