Rennie Collection’s latest: Richard Jackson, Georges Seurat & Jackson Pollock, guns, the act of painting, and women

My big reason (aside from my usual interest in/amused fascination by contemporary art) for catching the Richard Jackson show at 51 E. Pender St., Vancouver, Canada where you can find the Rennie Collection (can I call it a museum? a  gallery?) is that Jackson was an engineer. Or so I understood. I was intrigued by the idea of an engineer becoming a successful artist but after seeing the show I looked him up and found that according to his Wikipedia entry, he studied art and engineering.

He studied Art and Engineering at Sacramento State College from 1959–1961 and taught Sculpture and New Forms at UCLA Los Angeles 1989 – 1994.

So it seems that Jackson never worked as an engineer and I was a little saddened to lose that because it’s the kind of detail that makes the art even more interesting to me. Not being a visual artist or trained in art history, I primarily view art shows and the artists as collections of stories/narratives.

The Rennie Collection itself showcases only artists whose work is collected by Bob Rennie, a local and highly successful Vancouver realtor/developer/marketer. He’s no slouch in the art world, from an April 23, 2010 article by Maggie Langrick in The Vancouver Sun,

Vancouver’s ‘Condo King’ Rennie is a figure of international significance in the art world, a fact reflected in his recent appointment to the chair of the North American acquisitions committee at Britain’s Tate Modern Museum. His art collection includes works by more than 170 artists, 40 of whom he collects in depth.

The Wing Sang building that houses the collection has its own story which you can read here.

Jackson’s show, which runs until late Sept.,  is quite focused on bodily and other fluids, on the art world, and the act of painting in comparison to the Hatoum show which was the opening show for the gallery/museum which seemed  fixated on one’s sense of place, the themes of alienation and rootlessness, and electricity. Jackson’s work is very physical and he does most of it where Hatoum conceptualizes a piece and often commissions craftspeople to realize her concept. I mention the differences because it’s interesting to consider how different artists respond to the same space. I have no grand conclusions about their respective responses other than to point out that Jackson has physically melded many of his works to the building’s structure, paint is on the walls or on the floor and in some places he’s laid his own floor of puzzle pieces over top of the building’s floor.  In contrast, Hatoum’s work referenced the space obliquely. In the main floor gallery, Hatoum had affixed a sign to a wall to tell visitors how to behave. There was also a glass swing set (the type you played on when you were a kid, except it wasn’t glass) which in some ways had the effect of bringing the outdoors inside. I had some other comments about Hatoum’s show here.

Enough with the comparisons. Jackson’s work contains both humour and violence in jarring juxtoposition. I most appreciated his paintings where he uses canvases as his brushes. He dumps a puddle of acrylic paint on the front of a canvas and then picks it up and places it paint first against a wall and smooshes it around.  Once the canvas makes contact with the wall, the artist loses some control of the process.  Schematics for this piece in the main floor gallery are on the wall opposite so you can see some of the mural was planned but what happens on execution is uncontrolled. When Jackson is finished smooshing, he affixes his brush/canvas to the wall face first so the viewer is presented with the back of the canvas arranged in a pattern over parts of his mural.

This business of control and uncontrol and using unconventional ‘paint brushes’ comes up in another piece, La Grande Jatte (after Georges Seurat), an unfinished piece.

Jackson, a hunter, fires paint pellets from rifles (which are in a corner nearby)  at a huge sketch broken up into a grid (series of targets) of Seurat’s piece. For anyone not familiar with Seurat, he’s a pointillist who worked by precisely placing dots/points of paint on canvas. (This essay about Seurat offers a more informed perspective.)

There’s some dark humour in an artist who’s (a) shooting his own canvas with (b) pellets that explode on impact so the paint is splattered while referencing an artist who was known for his precision. Given that engineers are obsessed with precision and Richard Jackson studied engineering, some questions (nothing substantive, just interesting) arise. The whole piece brought to mind Jackson Pollock, an abstract artist, who poured and dripped paint from cans onto his canavases. (More about Pollock on Wikipedia.)

The theme of control/precision in relationship to spontaneity/chaos provided an interesting dynamic but not the only one. There was also an element of violence. The guns represent overt violence but two other pieces which were sculptural figures of women suggested, to me, violence of one kind or another. One figure was a woman in the colour pink lying on her back with her hips raised, legs opened and a funnel sticking out of her anus. I have two associations with that, a colonic or torture. The other figure was a ballerina who was knocked off her pedestal or stage so she was lying head first on the floor, legs up in the air, one ballet shoe off. There was a pool of paint/on the pedestal/stage and at least one more pool of paint, this one in the vicinity of the figure’s head. It’s one of a series as is the upside down woman, each with different colours. The ballerina’s pools of paint are red.

Both tour guides (one was in training) maintained that the experience of seeing the female figures as part of a series would change that impression of violence especially since the other figures in the series bore different colours. I don’t think that anyone could ever read a figure that’s fallen to the floor and has a pool of fluid by its head as anything other than wounded and the object of some sort of violence, intended or accidental.

I do think that the presence of additional figures in different colours would lead the discussion away from notions of personal violence to more generalized notions of violence in the way that this paraphrase of a quote attributed to Stalin, “One is a tragedy, a million is a statistic,”  does.

I found the show to be thought-provoking and that’s always to be appreciated. If you’re interested in other opinions about the show, there’s this excerpt from Robin Laurence‘s review at The Georgia Straight,

Jackson has been described as a neo-Dadaist, probably because of the bourgeoisie-baiting irreverence he brings to his projects. He’s also seen as someone who deconstructs painting, although he says he’s more interested in expanding its possibilities than in taking it apart. Still, he long ago assumed conceptualism’s stand against market-driven and craft-based approaches to the medium: he critiques the painting as a fetishized object while embracing the process of reinventing it. “I don’t like art,” he says, “I like the activity.”

Nonetheless, there is a lot of art on view, some of it temporary and all of it (as is true of every show produced in this venue) drawn from Rennie’s personal collection. Installed on the main floor is Rennie 101, a big wall work composed of semicircles of thick, vivid paint and stretched canvases. In executing this idea, Jackson loaded 20 small canvases with paint, then placed them face to the wall and rotated them, creating a series of concentric loops of colour. The canvases were then mounted, again face to the wall, in a corresponding grid formation. The entirety is a wonderful contradiction: geometric and organic, restrained and spectacular, it reflects not only the artist’s early studies in engineering but also his desire to invert and unsettle traditional forms and practices.

As you can tell, she knows a lot more about art than I do so it’s well worth your while to take a look at what she has to say. If you’re interested in the seeing the show, you can book here.

One last item, Clark Miller has posted about human enhancement on the NISE Net blog. Miller is the Associate Director of the Arizona State University (ASU), Consortium for Science, Policy and Outcomes. From his April 27, 2010 post,

The pursuit of science to enhance human performance raises profound questions for society. Yet, according to a recent study we conducted at the Center for Nanotechnology in Society at ASU, knowledge about nanotechnology and human enhancement is extremely low. This suggests the topic might be a good one for science museums to tackle. The full results of our survey will be published soon, but if any of you would like to find out more about the findings or are thinking about developing an exhibit or program around human enhancement, I’d be glad to talk further.

Perhaps the most important finding from the study is that the US public is, overall, quite skeptical regarding the prospect of human enhancement. This might be expected of sports, given the negative press that steroid use has gotten in recent years, but survey respondents also strongly objected to the use of enhancement technologies that would help in getting a job, taking a college entrance exam, or running for public office.

I have posted on this topic most recently here and in a four part series July 22, 2009, July 23, 2009, July 24, 2009 and  July 27, 2009. Gregor Wolbring at the University of Calgary writes on this issue extensively (from his blog called: Nano and Nano- Bio, Info, Cogno, Neuro, Synbio, Geo, Chem…),

Hi everybody, My name is Gregor Wolbring. I am an Ableism ethics and governance scholar, a biochemist, ethicist, governance of science and technology scholar , ability studies and governance scholar, disability studies,health research, implications of Nanotechnology, Converging Technologies, Synthetic Biology scholar. Beside that I am interested in social entrepreneurship, working with youth, social implications, human rights. My webpage is here; My biweekly column at innovationwatch.com is here ; My new blog on Ableism Ethics and Governance; A blog to which I also contribute called What Sorts of People

Andy Miah from the University of the West of Scotland also writes extensively on the topic of human enhancement here. From his About page,

“Andy Miah is the Renaissance man of the enhancement enlightenment”
Kristi Scott, H+ Magazine, 2009

My research is informed by an interest in applied ethics and policy related to emerging technology. I have spent considerable time researching the Internet along with human enhancement technologies. This includes the implications of pervasive wireless connectivity and the convergence of technological systems and the modification of biological matter through nanotechnology and gene transfer. Many of these studies are increasingly transdisciplinary and being characterised as NBIC (nano-bio-info-cognitive) inquiries. Recent work has particularly examined the role of art and design in an era of biotechnology, often described as bioart or transgenic art.

I have published over 100, solo-authored academic articles in refereed journals, books, e-zines, and national media press, recently including Bioethics and Film, Medical Enhancement and Posthumanity, and Politics and Leisure. I also write for leading newspapers, including The Washington Post, The Guardian, Le Monde, the Times Higher Education Supplement. …

Both Gregor and Andy offer some thought-provoking perspectives for anyone interested in the area of human enhancement.

Synbio (Synthetic Biology) in society a May 12, 2010 panel discussion hosted by the Project on Emerging Nanotechnologies

The proper title for this event, hosted by the Project on Emerging Nanotechnologies (PEN) is: Synbio in Society: Toward New Forms of Collaboration? which will be webcast live (I hope they’re able to pull that off this time) this coming Wednesday, May 12, 2010.  The time is listed as 12:30 pm ET (9:30 am PT) but a light lunch (for attendees at the Washington, DC live event) is also mentioned and the folks at PEN haven’t distinguished (as per their usual practice) the time that the panel starts.

From the news release,

One response to society’s concerns about synthetic biology has been to institutionalize the involvement of social scientists in the field. There have been a series of initiatives in which ethics and biosafety approaches have been purposely incorporated into synthetic biology research and development. The collaborative Human Practices model within the NSF-funded SynBERC project was the first initiative in which social scientists were explicitly integrated into a synthetic biology research program. But these new collaborations have also flourished in the UK where four research councils have funded seven scientific networks in synthetic biology that require consideration of ethical, legal and social issues. Another example is the US-UK Synthetic Aesthetics Project, which brings together synthetic biologists, social scientists, designers and artists to explore collaborations between synthetic biology and the creative professions.

Similarly, the European Commission’s Seventh Framework Programme funds projects like Synth-ethics, which “aims at discerning relevant ethical issues in close collaboration with the synthetic biology community.” (http://synthethics.eu/) and SYBHEL, which aims to examine ethical legal and social aspects of SynBio as it applies to health care (http://sybhel.org/).

On May 12, 2010, the Synthetic Biology Project at the Woodrow Wilson International Center for Scholars will present a panel discussion to explore new forms of collaboration that have emerged between scientists and social scientists working on synthetic biology. A distinguished group of speakers will explore the many ways in which the new science of synthetic biology–far from standing apart from the rest of the academic disciplines–is in constant conversation with the social sciences and the arts.

While I’m not a big fan of the whole synthetic biology movement, I do find this collaboration between sciences/social sciences/arts to be quite intriguing.

You can read more about the event or click on to the live streaming webcast on Weds. or RSVP to attend the actual event here.

Quite by chance I found out that Canada’s National Institute for Nanotechnology (NINT) includes synthetic biology in its programme focus. From the Nano Life Sciences at NINT page,

The Nano Life Sciences researchers investigate the fields of synthetic biology, computational biology, protein structure, intermolecular membrane dynamics and microfluidics devices for biological analysis.

* Synthetic biology is a young field that uses genetic engineering and DNA synthesis to develop new proteins and genetic circuits. Proteins are the nanoscale machinery of life while genetic circuits represent computational “logic” capabilities in cells. Research in this field could lead to a “toolkit” for “re-programming” bacteria to produce useful functions.

I haven’t been able to find any more details about the Canadian synbio endeavour on the NINT website.

Roundup of OECD’s recent nanomaterials publications

Last week the OECD (Organization for Economic Cooperation and Development) made three new publications available on their Safety of Manufactured Nanomaterials website. News items on Nanowerk offer a précis for each document.

From the news item about the results of a questionnaire about regulatory regimes that cover nanomaterials,

The current document presents the information obtained from the WPMN [Working Party on Manufactured Nanomaterials] Questionnaire on Regulatory Regimes for Manufactured Nanomaterials issued July 28, 2008. Responses received are summarized in the Tables (see Annexes). Twenty-four responses were received from nine jurisdictions for Legislations covering a wide variety of chemical substances and/or products including industrial chemicals, pesticides, fertilizers, agricultural compounds, fuels and fuel additives, food and food additives and veterinary medicines. Other Legislations reported included those covering occupational health and safety, consumer products, control of major accidents and labelling and packaging. Although a wide variety of sectors are represented in the data obtained, it is noted that responses from the industrial chemical sector were in the majority for those Legislations reporting pre-market and/or post-market registration/notification and assessment.

None of the respondents reported having legislation specific to nanomaterials, however most respondents indicated that the authority to regulate substances that are nanomaterials, or products containing nanomaterials, exists in current Legislation. [emphasis mine]

This questionnaire was filled out in 2008 and, to the best of my knowledge, the situation in Canada (one of the respondents) remains unchanged from that time. You can access the full report here although I suggest reading the item at Nanowerk first as it offers good preparation for the full report and I have had problems with downloading at least one of these reports from the OECD site and from the link provided at Nanowerk.

There’s a workshop report on risk assessment (from the news item on Nanowerk),

The workshop took place September 16th – 18th, 2009 in Washington D.C., United States, and was cohosted by the Business and Industry Advisory Committee (BIAC) and the Society for Risk Analysis. Seventy (70) participants representing OECD member countries, non-member economies, industries, academia and environmental NGOs attended.

Following general presentations and discussions, case studies on Titanium dioxide nanomaterials, Silver Nanomaterials and Carbon Nanotubes were presented. Workshop attendees then participated in one of five parallel break-out sessions to discuss specific issues of risk assessment methodology including i) Assessment Problem Formulation; ii) Exposure – Public, Occupational and Environment; iii) Hazard – Human Health; iv) Ecological Toxicity and Fate; and v) Determining Risk and Linkage between Assessment and Management.

Workshop participants concluded that the risk assessment paradigm for chemicals will continue to guide approaches to the risk assessment of nanomaterials. However, because of the limited amount of empirical data on nanomaterials, many of the assumptions and estimations employed in chemical risk assessments need to be evaluated for nanomaterials.

If I understand the last two sentences properly, this means that as products continue to enter the marketplace the old rules will apply although nanomaterials may behave in completely unexpected ways so more research is needed. (As per the last report, you can access the full report here although I suggest reading the item at Nanowerk first as it offers good preparation for the full report and I have had problems with downloading at least one of these reports from the OECD site and from the link provided at Nanowerk.)

The third member of this trio of reports is a 2009-2012 operational plan for the OECD’s nanomaterials safety programme. From the news item on Nanowerk,

The OECD programme on the safety of manufactured nanomaterials aims to ensure that the approach to hazard, exposure and risk assessment is of a high, science-based, and internationally harmonised standard.

This programme promotes international co-operation on the human health and environmental safety of manufactured nanomaterials, and involves safety testing and risk assessment of manufactured nanomaterials. This document compiles the operational plans (2009-2012) for the implementation of each project of the Working Party on Manufactured Nanomaterials (WPMN).

There are six projects,

1. OECD Database on Manufactured Nanomaterials to Inform and Analyse EHS Research Activities [led by SG1/2]…

2. Safety Testing of Representative Set of Manufactured Nanomaterials [led by SG3] – …

3. Manufactured Nanomaterials and Test Guidelines [led by SG4] – …

4. Co-operation on Voluntary Schemes and Regulatory Programmes [led by SG5] – …

5. Co-operation on Risk Assessment [led by SG6] – …

6. The Role of Alternative Test Methods in Nanotoxicology [led by SG7] – …

7. Co-operation on Exposure Measurement and Exposure Mitigation [led by SG8] – …

8. Environmentally Sustainable Use of Manufactured Nanomaterials [led by SG9] …

It seems a bit odd to me that a plan which covers 2009 to 2012 is released in 2010 as it seems to be somewhat after the fact. (As per the last report, you can access the full report here although I suggest reading the item at Nanowerk first as it offers good preparation for the full report and I have had problems with downloading at least one of these reports from the OECD  site and from the link provided at Nanowerk.)

Quantum kind of day: metaphors, language and nanotechnology

I had a bonanza day on the Nanowerk website yesterday as I picked up three items, all of which featured the word ‘quantum’ in the title and some kind of word play or metaphor.

From the news item, Quantum dots go with the flow,

Quantum dots may be small. But they usually don’t let anyone push them around. Now, however, JQI [Joint Quantum Institute] Fellow Edo Waks and colleagues have devised a self-adjusting remote-control system that can place a dot 6 nanometers long to within 45 nm of any desired location. That’s the equivalent of picking up golf balls around a living room and putting them on a coffee table – automatically, from 100 miles away.

There’s a lot of detail in this item which gives you more insight (although the golf ball analogy does that job very well) into just how difficult it is to move a quantum dot and some of the problems that had to be solved.

Next, A quantum leap for cryptography,

To create random number lists for encryption purposes, cryptographers usually use mathematical algorithms called ‘pseudo random number generators’. But these are never entirely ‘random’ as the creators cannot be certain that any sequence of numbers isn’t predictable in some way.

Now a team of experimental physicists has made a breakthrough in random number generation by applying the principles of quantum mechanics to produce a string of numbers that is truly random.

‘Classical physics simply does not permit genuine randomness in the strict sense,’ explained research team leader Chris Monroe from the Joint Quantum Institute (JQI) at the University of Maryland in the US. ‘That is, the outcome of any classical physical process can ultimately be determined with enough information about initial conditions. Only quantum processes can be truly random — and even then, we must trust the device is indeed quantum and has no remnant of classical physics in it.’

This is a drier piece (I suspect that’s due to the project itself) so the language or word play is in the headline. I immediately thought of a US tv series titled, Quantum Leap where, for five seasons, a scientist’s personality/intellect/spirit is leaping into people’s bodies, randomly through time. There are, according to Wikipedia, two other associations, a scientific phenomenon and a 1980s era computer. You can go here to pursue links for the other two associations. This is very clever in that you don’t need to have any associations to understand the base concept in the headline but having one or more association adds a level or more of engagement.

The final item, Scientists climb the quantum ladder,

An EU [European Union]-funded team of scientists from Cardiff University in the UK has successfully fired photons (light particles) into a small tower of semiconducting material. The work could eventually lead to the development of faster computers. …

The scientists, from the university’s School of Physics and Astronomy, said a photon collides with an electron confined in a smaller structure within the tower. Before the light particles re-emerge, they oscillate for a short time between the states of light and matter.

While I find this business of particles oscillating between two different states, light and matter, quite fascinating this particular language play is the least successful. I think most people will do what I did and miss the relationship between the ‘tower’ in the news item’s first paragraph and the ‘ladder’ in the headline. I cannot find any other attempt to play with either linguistic image elsewhere in the item.

Given that I’m  a writer I’m going to argue that analogies, metaphors, and word play are essential when trying to explain concepts to audiences that may not have your expertise and that audience can include other scientists. Here’s an earlier posting about some work by a cognitive psychologist, Kevin Dunbar, who investigates how scientists think and communicate.

Science and scientists in the movies and on tv

I find it easy to miss how much science there is in the movies and on television even though I’m looking for it. Here are a few recent examples of science in popular culture.

Inside Science of Iron Man 2, an article by Emilie Lorditch on physorg.com explains some of the background work needed to create a giant particle accelerator with a new way to power the reactor pumping Iron Man’s heart. From the article,

“I went to Marvel Studios to meet with one of the film’s producers (Jeremy Latcham) and even brought a graduate student along,” said Mark Wise, a theoretical physicist at the California Institute of Technology in Pasadena who served as a technical consultant for the film. “There was a specific set of scenes that I was consulting on; the story had to get from this point to that point.”

Wise was surprised by Latcham’s and the film crew’s interest in the actual science, “I attempted to present the science in a way to the help the movie, but still get a little science in,” said Wise. “They wanted the scenes to look good, but they also wanted elements of truth in what they did, it was nice.”

The producers for the film found their scientist through The Science and Entertainment Exchange (which is a program of the US National Academy of Sciences). From Lorditch’s article,

“Scientists can offer more than just simple fact-checking of scripts,” said Jennifer Ouellette, director of the Science and Entertainment Exchange. “Get them involved early enough in the production process and their input can be invaluable in developing not just the fundamental scientific concepts underlying a scene, but also — since film and TV are a visual mediums — scientists can help filmmakers more fully realize their visions on screen.”

I have blogged before about Hollywood’s relationship with science here although my focus was largely on mathematics and the Canadian scene.

Dave Bruggeman at the Pasco Phronesis blog regularly highlights science items on television. Much of his focus is on late night tv and interviews with scientists. (The first time I saw one of his posts I was gobsmacked in the best way possible since I’d taken the science element of these talk show interviews for granted.) There’s another Pasco Phronesis posting today about the latest Colbert Report and a series Colbert calls, Science Cat Fight.

All of this is interesting fodder for thinking about how scientists (and by extension science) are perceived and Matthew C. Nisbet at the Framing Science blog has some interesting things to say about this in his posting ‘Reconsidering the Image of Scientists in Film & Television‘,

Contrary to conventional wisdom that entertainment media portray science and scientists in a negative light, research shows that across time, genre, and medium there is no single prevailing image and that both positive and negative images of scientists and science can be found. More recent research even suggests that in contemporary entertainment media, scientists are portrayed in an almost exclusively positive light and often as heroes.

Nisbet goes on to offer four ‘archetypes’ and ask for feedback, (Note: I have removed some of the text from these descriptions.)

Scientists as Dr. Frankenstein: …  Examples of this image include Gregory Peck as Dr. Mengele in Boys from Brazil, Marlon Brando as Dr. Moreau in The Island of Dr. Moreau, and Jeff Goldblum as the scientist in The Fly.Scientists as powerless pawns: … Examples include Robert Duvall as Dr. Griffin Weir in the 6th Day and several of the scientists in Jurassic Park who work for Richard Attenborough’s character John Hammond, CEO of InGen.

Scientists as eccentric and anti-social geeks: … Examples of this image include Christopher Loyd as Doc in Back to the Future, the nerdy boys in John Hughes 1985 film Weird Science who use science to create the perfect woman, and Val Kilmer and his fellow grad students in the 1985 film Real Genius who serve as graduate students to a professor who is determined to master a Star Wars-like satellite technology. [my addition: The characters in The Big Bang Theory.]

Scientists as Hero: …  Examples include Dr. Alan Grant as the main protagonist in Jurassic Park, Spock in the new version of Star Trek who takes on leading man and action hero qualities to rival Captain Kirk, Jody Foster’s character in Contact, Sigourney Weaver’s character in Avatar, Denis Quaid as the climate scientist hero in The Day After Tomorrow, Chiwetel Ejiofor as the geologist hero in 2012, Morgan Freeman in the Batman films as inventor Lucious Fox and CEO of Wayne Industries, and Robert Downey Jr. as Tony Stark in the Iron Man films.

Serendipitously, I’ve returned to where I started: Iron Man. As for all this science in the media, I think it’s a testament to its ubiquity in our lives.

Canada’s national animal builds world’s largest dam (you can see it from space)

For those who don’t know, Canada’s national animal is the beaver. At least, that’s what I was taught and have believed for many years,  so you can imagine my surprise when I found out that Canada has a second national animal, the Canadian horse. I think the reason for the sudden appearance of  a second national animal is perfectly obvious since the word ‘beaver’ has become a dirty joke.

This was brought sharply to mind the other day when I saw the headline, World’s biggest beaver dam discovered in northern Canada [in the province of Alberta], on physorg.com. It’s a pretty amazing dam, from the news item,

Researcher Jean Thie said Wednesday he used satellite imagery and Google Earth software to locate the dam, which is about 850 metres (2,800 feet) long on the southern edge of Wood Buffalo National Park.

Average beaver dams in Canada are 10 to 100 metres long, and only rarely do they reach 500 metres.

First discovered in October 2007, the gigantic dam is located in a virtually inaccessible part of the park south of Lac Claire, about 190 kilometres (120 miles) northeast of Fort McMurray.

Apparently, the beavers started on this project in the mid-1970s and many generations have worked on it. In fact, they are still building it. I wonder if one could describe it as a kind of beaver metropolis?

While I was meditating on these beavers and their dam, I remembered that Canada’s History magazine made this announcement in January 2010 (from a Reuters news article),

Canada’s second-oldest magazine, The Beaver, is changing its name because its unintended sexual connotation has caused the history journal to become snagged in Internet filters and has turned off potential readers.

The Beaver was founded in 1920 as a publication of the Hudson’s Bay Company, then a fur trader and now a department store chain. It has long since become a broader magazine about Canadian history and will change its name to Canada’s History with its April issue, editor-in-chief Mark Reid said on Tuesday.

When The Beaver started publication, the name evoked only Canada’s thriving fur industry.

Actually, it evoked a little more than just the fur trade. From this Wikipedia essay,

The beaver’s emblematic status originated from the fact much of Canada’s early economic history was tied to the fur trade in beaver fur, used to make hats fashionable in Europe. Another reason for the beaver’s status in Canadian heraldry is that it is symbolic of industry, due to its habit of constructing dams and lodges. [emphasis mine]

I remember the industriousness aspect largely because in grade one we were split into two groups, ‘busy bees’ and ‘??? beavers’. I was in the beaver group and somewhat miffed since I had (and have) a strong preference for alliterative phrases and ours (whatever it was) most definitely was not. As a murmur of protest rose (I was not alone in this), the teacher did note that beavers are just as hardworking as bees and Canada’s national animal.

Today, I’d like to take the word beaver back from sniggerers. After all, double entendres do change over time and I believe it’s time to rehabilitate this one. To encourage this, here’s a picture of the innocent animal,

he was happily sitting back and munching on something. and munching, and munching...

The image was taken by Steve and is available at Wikipedia on this page. It is known as the North American Beaver (Castor canadensis). There are two types of beavers (North American and European) and they are genetically incompatible.

Oil spills, environmental remediation, and nanotechnology

Oil spills have been on my mind lately as I’ve caught some of the overage about the BP (British Petroleum) oil spill in the Gulf of Mexico. One  leak (the smallest) has been fixed according to a news item on physorg.com

Days of work off the coast of Louisiana with underwater submarines nearly a mile below the surface finally bore fruit as a valve was secured over the smallest of the three leaks and the flow shut off.

The feat does not alter the overall amount of crude spilling into the sea and threatening the fragile US Gulf coast, but is significant nonetheless as the focus can now narrow on just two remaining leaks.

“Working with two leaks is going to be a lot easier than working with three leaks. Progress is being made,” US Coast Guard Petty Officer Brandon Blackwell told AFP.

More than two weeks after the Deepwater Horizon rig exploded, the full impact of the disaster is being realized as a massive slick looms off the US Gulf coast, imperilling the livelihoods of shoreline communities.

The news item goes on to detail how much crude oil is still being lost, the oil slick’s progress, the probable impact on the shoreline and animals, and the other efforts being made to ameliorate the situation.

With all the talk there is about nanotechnology’s potential for helping us to clean up these messes, there’s been no mention of it in the current  efforts as Dexter Johnson over at the IEEE’s (Institute of Electrical and Electronics Engineers)  Nanoclast blog pointed out the other day. From Dexter’s posting which features both a  discussion about patents for nanotechnology-enabled clean up products and an interview with Tim Harper,

So to get a sense of where we really are I wanted to get the perspective of my colleague, Tim Harper (principal of Cientifica), who in addition to being a noted expert on the commercialization of nanotechnologies also has devoted his attention to the use of nanotechnologies in cleantech including its remediation capabilities, leading him to his presentation this week in Australia at the conference Cleantech Science and Solutions: mainstream and at the edge.

“If you are looking for a quick fix from nanotechnology, forget it,” says Harper. “Nanotech is already making an impact in reducing energy, and therefore oil use, it is also being used to create stronger lighter materials that can be used for pipelines, and enabling better sensors for early warning of damage, but in terms of cleaning up the mess, the contribution is minor at best.”

Clearly not the hopeful words that many would have hoped for, and the pity is that it might have been different, according to Harper.

“As with all technologies, the applications take a while to develop,” he says. “If someone had come up with some funding 10 years ago for this specific application then we may have had better tools to deal with it.”

Dexter’s posting about patents and Harper’s comments reminded me of an article by Mason Inman I saw two years ago on the New Scientist website titled, Nanotech ’tissue’ loves oil spills, hates water. From the article,

A material with remarkable oil-absorbing properties has been developed by US researchers. It could help develop high-tech “towels” able to soak up oil spills at sea faster, protecting wildlife and human health.

Almost 200,000 tonnes of oil have been spilled at sea in accidents since the start of the decade, according to the International Tanker Owners Pollution Federation. [This article was posted May 30, 2008]

Clean-up methods have improved in recent years, but separating oil from thousands of gallons of water is still difficult and perhaps the biggest barrier to faster clean ups.

The new water-repellent material is based on manganese oxide nanowires and could provide a blueprint for a new generation of oil-spill cleaners. It is able to absorb up to 20 times its own weight in oil, without sucking up a drop of water.

Unfortunately,

But [Joerg] Lahann [University of Michigan in Ann Arbor, US]  points out that manganese oxide may not be the best material for real-world applications because it could be toxic. He says, though, that the new material “clearly provides a blueprint that can guide the design of future nanomaterials for environmental applications.”

I wonder if they’ve done any research to determine if manganese oxide in the shape and size required to create this nanotech ’tissue’ is toxic. Intriguingly, there was a recent news item on Nanowerk about toxicology research in a marine environment being undertaken.

Led by Dr. Emilien Pelletier, the Institut des Sciences de la Mer de Rimouski at the Université du Québec à Rimouski has obtained an LVEM5 benchtop electron microscope to help them study the short-term and long-term effects of nano-materials on the marine environment.

Dr. Pelletier is the Canada Research Chair in Marine Ecotoxicology. The overall objective of the chair is to understand the impact of natural and anthropogenic stresses on the short-and long-term high-latitude coastal ecosystems to contribute to the conservation, protection and sustainable development of cold coastal marine resources.

Since the news release was written by the company supplying the microscope there is no word as to exactly what Emilien’s team will be researching and how the work might have an impact on other members of the community such as the researchers with the ‘oil-hungry nanotech tissue’ made of nanoscale manganese oxide.

There is as always a political element to all of this discussion about what we could or couldn’t do with nanotechnology-enabled means to clean up oil spills and/or reduce/eliminate our dependence on oil. This discussion is not new as Dr. J. Storrs Hall implies during a presentation being reported in a recent (May 4, 2010) Foresight Institute blog entry by Dave Cronz, PhD. From the posting,

Here I offer my reflections on some of the highlights of the presentation by Dr. J. Storrs Hall of the Foresight Institute, entitled “Feynman’s Pathway to Nanomanufacturing,” and the panel discussion that followed, “How Do We Get There from Here?” Discussions such as these are crucial opportunities to reflect on – and potentially shape – emerging technologies whose destinies are often left to be determined by “market forces.”

Dr. Hall began with an intriguing argument: Feynman’s top-down approach to reaching the nano scale in manufacturing, achieved through a step-down method of replicating and miniaturizing an entire, fully-equipped machine shop in 1:4 scale over and over would yield countless benefits to science, engineering, and manufacturing at each step. These microscopic, tele-manipulated master-slave “Waldos” (named after Heinlein’s 1942 story “Waldo F. Jones”) would get nanotechnology back on track by focusing on machines and manufacturing, since most of our current emphasis is on science at the nano scale. Feynman’s top-down approach to nanoscale manufacturing is missing from the Foresight Institute’s roadmap, according to Hall, “for political reasons.” This raises a fundamental point: science and technology cannot develop independent of the political and social spheres, which pose as many challenges as the technology. Many would argue that social and technological processes are inseparable and treating them otherwise borders on folly. I commend Dr. Hall for offering his argument. It soon became clear that the panelists who joined him after his presentation disagreed. [bolded emphases mine]

As Dr. Hall aptly noted it’s not dispassionate calculations but “serendipity: the way science always works.”

I’m in agreement with Dr. Hall, the political and social spheres are inseparable from the scientific and technological spheres. As for “emerging technologies whose destinies  are often left to be determined by market forces”, Dexter’s posting ends with this,

But foresight is not the strong suit of businesses built around short-term profit motives as evidenced by them [BP] not even investing in the remote systems that would have turned the oil well off and possibly avoided the entire problem.

I strongly recommend reading Dexter’s posting to get the nuances and to explore his links.

I’m going to finish on a faint note of hope. There is work being done on site remediation and it seems to be successful, i.e., nonpolluting, less disruptive to the environment, and cheaper.  The Project on Emerging Nanotechnologies (PEN) has a webcast of a presentation titled, Contaminated Site Remediation: Are Nanomaterials the Answer?. You can find my comments about the webcast here (scoll down a bit) and PEN’s Nanoremediation Map which lists projects around the world although most are in the US. It’s incomplete since there is no requirement to report a nanoremediation site to PEN but it does give you an idea of what’s going on. Canada has two sites on the map.

GENNESYS

GENNESYS (Grand European Initiative on Nanoscience and Nanotechnology using Neutron- and Synchrotron Radiation Sources) is a report (released April 2010), a conference (to take place May 26-28, 2010 in Barcelona, Spain), and a five-year project about nanomaterials that was undertaken in Europe. The report is some 500 pages long and Michael Berger offers a précis in a Nanowerk Spotlight article.  From Berger’s article,

A European project [GENNEYSIS] has completed an extensive five-year study of the needs and opportunities for coordinating future research and development in nanomaterials science and nanotechnology for the advancement of technologies ranging from communication and information, health and medicine, future energy, environment and climate change to transport and cultural heritage.

With over 600 participating ‘authors’, the report offers a comprehensive view of the European perspective. The objectives for the project were (from the report, p.viii),

The key objectives of the GENNESYS task forces were:

• To assess the “state of the art” of nanoscience and technology in Europe;

• To identify future needs, opportunities and priorities in the field of nanomaterials science for solving urgent problems in Europe and around the world;

• To articulate fundamental scientific challenges, society needs and industrial potentials in this field;

• To define recommendations and objectives for future research, technologies, and development strategies which will lead to major advances;

• To pinpoint areas of research into nanomaterials science and technology that will most benefit from joint research strategies with synchrotron radiation and neutron facilities;

• To review and forecast the effects that a strategic use of large-scale facilities by nanomaterials scientists will have on the facilities;

• To provide evidence of the societal impact of the field and provide a forum for coordinated community-wide communications between basic researchers, industry, policy-makers and the public, respectively;

• To establish a strategic European research programme encapsulated “Nanomaterials research and technology for future technologies exploiting neutron and accelerator-based x-ray facilities”.

I would strongly recommend reading Berger’s article where he offers a summary of the high points before tackling this extraodinary report (the list of authors and contributors spans 30 pages).

Biomimicry, proteins, muscles, and the University of British Columbia’s Dr. Hongbin Li

This morning, I was excited to receive a news release about Dr. Hongbin Li’s recent work which has been published in Nature magazine. A Canada Research Chair in Molecular Nanoscience  and Protein Engineering at the University of British Columbia (Canada), Dr. Li’s work has been featured here before. (Part 1 and Part 2 of the interviews where he patiently answered my uninformed questions about his 2008 work on proteins where he had them behave like shock absorbers.) This latest work builds on his 2008 discoveries and extends them as he considers muscle elasticity.

From the news release,

University of British Columbia researchers have cast artificial proteins into a new solid biomaterial that very closely mimics the elasticity of muscle.

The approach, detailed in the current issue of the journal Nature, opens new avenues to creating solid biomaterials from smaller engineered proteins, and has potential applications in material sciences and tissue engineering.

“There are obvious long-term implications for tissue engineers,” says Hongbin Li, associate professor in the Dept. of Chemistry. “But at a fundamental level, we’ve learned that the mechanical properties we engineer into the individual proteins that make up this biomaterial can be translated into useful mechanical properties at the larger scale.”

The work will be published tomorrow “Designed biomaterials to mimic the mechanical properties of muscles” by Shanshan Lv, Daniel M. Dudek, Yi Cao, M. M. Balamurali, John Gosline, Hongbin Li in Nature 465, 69-73 (6 May 2010) doi:10.1038/nature09024 Letter.

Again from the news release,

The mechanical properties of these biomaterials can be fine-tuned, providing the opportunity to develop biomaterials that exhibit a wide range of useful properties – including mimicking different types of muscles. The material is also fully hydrated and biodegradable.

I wonder where are these ‘muscles’ going to appear? On robots?

Congratulations to Dr. Hongbin Li and your colleagues, Shanshan Lv, Daniel M. Dudek, Yi Cao, M. M. Balamurali, and John Gosline.
