Nano-enhanced marine products make boats and ships lighter

A leader in marine closures? Apparently this is Pacific Coast Marine’s claim to fame and they are now announcing a new line of products with nano-enhanced (?) carbon fibers. (I’ve not come across the term ‘nano-enhanced’ before. Is this a new marketing term?) According to the June 25, 2012 news item on Nanowerk,

Zyvex Marine, a division of Zyvex Technologies, and Pacific Coast Marine announced a partnership to make the industry’s lightest and most durable doors, hatches, and other marine closures using nano-composites. …

Zyvex Marine, the pioneer of the 54′ boat Piranha that weighs 8,000 pounds yet would have weighed 40,000 pounds with traditional materials, is a leader in watercraft and component manufacturing using carbon nanotube-enhanced carbon fiber materials.

Pacific Coast Marine, a leader in marine closures for nearly 30 years, worked with Zyvex during the last year to develop doors, hatches and closures for current watercraft produced by Zyvex Marine. Now recognizing greater commercial opportunities for lightweight doors and hatches on its boats, Pacific Coast Marine and Zyvex are unveiling a door that weighs 66% less than a traditional door – from 150 pounds to just 50 pounds each – and is more durable.

Both Zyvex Marine and Pacific Coast Marine are nearby neighbours being just a few hours south of Vancouver (Canada) in Washington State.

Here’s a little more about Zyvex Marine from the company’s About page,

Zyvex is the premier provider of carbon fiber nano-composites vessels and specializes in manned and unmanned variants for an array of operating conditions using the most advanced materials science available.

Zyvex Marine formally became a division of Zyvex Technologies in November 2011 and has a storied history dating back to 2009. In early 2009, the world’s first commercialized carbon nanotube enhanced (CNTe) carbon fiber material, Arovex, enabled the design of a prototype vessel called the 540SE. Setting new standards for fuel efficiency and performance, the lightweight 540SE hull offered a 75% reduction in fuel consumption costs, translating to increased range and lower operating costs.

In 2010, Zyvex Marine manufactured its first prototype craft, the Piranha USV Concept, taking it from the drawing board and into the water in under one year. Setting new standards in range, speed, sea keeping and payload for unmanned vessels, the Piranha USV Concept is a generational leap beyond boats built out of traditional materials like fiberglass or aluminum.

In 2011 Zyvex Marine shipped the first production nano-composite vessel, a lightweight 54′ boat. It set new standards for an unmanned vessel in the areas of range, speed, sea keeping and payload, fulfilling the promises made by the original Piranha USV Concept.

As for Pacific Coast Marine, from the Home page,

Pacific Coast Marine began building its reputation for nearly 30 years by supplying rugged and very high quality marine closures for the North Pacific and worldwide work boat fleets. PCM now is the largest supplier of high quality marine doors, windows and hatches in the world. Applications include superyachts, cruise ships, ocean tugs, ocean crew boats, offshore oil platforms, military vessels, fast ferries and merchant ships. The marine environment demands the very best, and that is PCM.

Given how much traffic there is on the seas, more fuel efficiency seems like a good step forward to using fewer resources. I am assuming, of course, that it doesn’t encourage yet more traffic. I notice that these products can also be used for offshore oil platforms, a topic of some interest in the province of British Columbia where I live.

GRAND offers $7500 for innovative media

The Canadian government funds a set of initiatives known collectively as the Network Centres of Excellence (NCE). GRAND (Graphics, Animation, and New Media), is located in Vancouver, BC. Here’s how the agency describes itself (from the About GRAND webpage),

GRAND is a research network and commercialization engine whose goal is to address complex issues in digital media and transform multidisciplinary research into user-centred solutions. GRAND will explore the use and application of digital media in a variety of settings including entertainment, healthcare, education, environmental sustainability, and public policy.

GRAND is a federally-funded Network of Centres of Excellence supporting 34 research projects divided into 5 cross-pollinating themes involving researchers at 25 universities across Canada with more than 60 industry, government, and nonprofit partners.

Aug. 19, 2011 there was an announcement that GRAND was getting a funding boost for commercialization projects (from the Aug. 19, 2011 news release),

The Canadian government, through Western Economic Diversification (WD), announced a funding commitment to boost GRAND’s research commercialization initiatives. The two-year agreement will support technology transfer, start-up creation, prototype development and networking events.  WD’s $399,000 will be matched by GRAND and industry for a total investment of $649,000 for the digital media economies of BC, Alberta, Saskatchewan and Manitoba.

The program expects to develop nine technology prototypes, conduct 40 technology demonstrations and bring nine technologies to market.

Coincidentally or not, Mark Salopek, GRAND’s Manager of Technology Transfer and Commercialization, made this announcement via a Nov. 18, 2011 article by Dan Verhaeghe on Techvibes,

Grand is offering $7500 to any company that is willing to employ one of the program’s PH.D student researchers to build the frameworks of innovation towards a goal that will help Canada continue to become a world leader in the digital media industry in any of the latter sectors mentioned.

Verhaeghe’s article mentions computing, simulation, 3D, and gaming technology sectors in addition to the graphics, animation, and new media technology sectors mentioned in GRAND’s own profile.

If you are interested in getting more details, contact Mark Salopek by e-mail here. Certainly, I have a few questions, how long would you have to employ someone? Are the funds for a salary? How much work do you have to do to get this money (anyone who’s ever filled out a government grant application will tell you that it is an arduous process)? Is there some sort of reporting process for outcomes and how much work is involved with writing that up? Is there a pool of PhD students to choose from or do you go out and find one yourself? Is there a deadline? Why isn’t there any information about this grant on the GRAND website?

Science and Arts Expo on May 17, 2011 in Victoria, BC

They’ve billed it as an arts/science expo but really, it’s a careers day event with a strong focus on science and industries such as entertainment media and mining. It’s being hosted by the Year of Science (a BC government initiative) and held from 10 am to 7 pm today, May 17, 2011, at the Royal British Columbia Museum. The sponsors for the event are Pfizer and an organization named, Canada’s research-based pharmaceutical companies. (For those who don’t know, Pfizer is a pharmaceuticals company.)

I was excited until I read the programme and realized it’s pretty much like to going to Science World. You can ooh and aah at the exhibits and demos but there’s nothing really engaging for either a child or an adult. It contrasts strongly with some of the projects I see elsewhere as I noted in my March 3, 2011 posting where amongst others, I profiled Blackawton bees, a paper that was peer-reviewed and published in the highly reputable Royal Society’s Biology Letters. The authors ranged in age from eight to 10 years old. They were not in a gifted class but they were being taught by a scientist who decided that the best way to share his passion for science was to encourage these kids to ask their own science question and answer it through experimentation.

‘Show and tell’ science events can be quite pleasurable and informative but there are other ways engage in and share science which you’d never know by attending a science event in BC.

International Year of Chemistry

ChemQuest 2011, an event honouring the International Year of Chemistry, is being hosted by Year of Science BC, Simon Fraser University, and Douglas College on May 14, 2011 from 1 pm to 4 pm on the Academic Quadrangle at Simon Fraser University’s Burnaby Campus.

This isn’t the only such event in Canada. Last week, there was a chemistry marathon (part of a larger initiative, 24 heures de science), La chimie pour tous (Chemistry for everyone) from 12 noon to 12 midnight at Université de Montréal. Isabelle Burgun wrote up an interview, for Agence Science-Presse, that she had with the chemist leading this public engagement event, Andreea Schmitzer. From the interview,

ASP – À qui s’adresse cette activité?

AS — Nous désirons sensibiliser la population et insuffler aux jeunes le goût de devenir chimiste! Mais nous visons surtout les plus jeunes, car le goût pour la science s’acquiert très jeune et puis, voir l’émerveillement scientifique dans les jeux [sic] d’un enfant n’a pas de prix!

ASP — La chimie, vous êtes tombée dedans quand vous étiez petite…

AS — J’ai effectivement découvert la chimie enfant, avec mon grand-père, qui était un passionné de science, la physique et la chimie en particulier. On faisait ensemble toutes sortes de manipulation dans le garage. À 6 ans, j’étais fascinée par tout ce qu’on pouvait apprendre et comprendre en manipulant des molécules, et c’est exactement ce que je fais aujourd’hui en recherche. Cette passion héritée de mon grand-père, j’ai à mon tour le goût de la transmettre aux jeunes et aux moins jeunes.

My rough translation:

Who is your audience for this event?

We want to raise public awareness and we want to inculcate in youth the desire to become chemists. But we’re particularly interested in inspiring young children because one acquires an interest in science at a young age and seeing the wonder at science in a child’s eyes has no price.

You were very young when you tumbled into a passion for chemistry.

I discovered chemistry very young, with my grandfather who was passionate about science, physics and chemistry in particular. We performed all kinds of experiments in the garage. At the age of six, I was fascinated by what you could learn and understand by manipulating molecules and that’s exactly what I do in my research today. This passion I inherited from my grandfather is what I want to pass on to the young and the not so young.

That’s it, I’m in a rush this morning. I’ll come back later to fix mistakes. Meanwhile, hope to see you at Northern Voice today or tomorrow.

Nanocellulose fibres, pineapples, bananas, and cars

Brazilian researchers are working on ways to use nanocellulose fibres from various plants to reinforce plastics in the automotive industry. From the March 28, 2011 news item on Nanowerk,

Study leader Alcides Leão, Ph.D., said the fibers used to reinforce the new plastics may come from delicate fruits like bananas and pineapples, but they are super strong. Some of these so-called nano-cellulose fibers are almost as stiff as Kevlar, the renowned super-strong material used in armor and bulletproof vests. Unlike Kevlar and other traditional plastics, which are made from petroleum or natural gas, nano-cellulose fibers are completely renewable.

“The properties of these plastics are incredible,” Leão said, “They are light, but very strong — 30 per cent lighter and 3-to-4 times stronger. We believe that a lot of car parts, including dashboards, bumpers, side panels, will be made of nano-sized fruit fibers in the future. For one thing, they will help reduce the weight of cars and that will improve fuel economy.”

Besides weight reduction, nano-cellulose reinforced plastics have mechanical advantages over conventional automotive plastics, Leão added. These include greater resistance to damage from heat, spilled gasoline, water, and oxygen. With automobile manufacturers already testing nano-cellulose-reinforced plastics, with promising results, he predicted they would be used within two years. [emphasis mine]

This sounds very similar to the work being done by FPInnovations with wood cellulose in Québec and in BC. I did post an interview with Dr. Richard Berry, Aug. 27, 2010 (http://www.frogheart.ca/?p=1922) where he described and discussed what FPInnovations calls  nanocrystalline cellulose. Coincidentally, Mark MacLachlan is giving a talk about nanocrystalline cellulose  at the Café Scientifique meeting in Vancouver tomorrow, March 29, 2011. Check my March 25, 2011 posting for more details.

Here’s a description of cellulose and the process by which the Brazilian researchers are extracting nanocellulose fibres (from the news item),

Cellulose is the main material that makes up the wood in trees and other parts of plants. Its ordinary-size fibers have been used for centuries to make paper, extracted from wood that is ground up and processed. In more recent years, scientists have discovered that intensive processing of wood releases ultra-small, or “nano” cellulose fibers, so tiny that 50,000 could fit inside across the width of a single strand of human hair. Like fibers made from glass, carbon, and other materials, nano-cellulose fibers can be added to raw material used to make plastics, producing reinforced plastics that are stronger and more durable.

Leão said that pineapple leaves and stems, rather than wood, may be the most promising source for nano-cellulose. He is with Sao Paulo State University in Sao Paulo, Brazil. Another is curaua, a plant related to pineapple that is cultivated in South America. Other good sources include bananas; coir fibers found in coconut shells; typha, or “cattails;” sisal fibers produced from the agave plant; and fique, another plant related to pineapples.

To prepare the nano-fibers, the scientists insert the leaves and stems of pineapples or other plants into a device similar to a pressure cooker. They then add certain chemicals to the plants and heat the mixture over several cycles, producing a fine material that resembles talcum powder. The process is costly, but it takes just one pound of nano-cellulose to produce 100 pounds of super-strong, lightweight plastic, the scientists said.

Since the Brazilian researchers are claiming that they will be introducing nanocellulose fibres into plastics within two years, I wonder if that has accelerated  the timeframe for applications (coatings, films, and textiles according to Dr. Berry) from FPInnovations and their nanocrystalline cellulose?

Phylo and crowdsourcing science by Canadian researchers

Alex Kawrykow and Gary Roumanis from McGill University (Montréal, Québec) have launched Phylo, a genetics game that anyone can play but is actually genetic research. From the article by Neal Ungerleider at the Fast Company website,

The new project, Phylo, was launched by a team at Montreal’s McGill University on November 29. Players are allowed to recognize and sort human genetic code that’s displayed in a Tetris-like format. Phylo, which runs in Flash, allows users to parse random genetic codes or to tackle DNA patterns related to real diseases. In a random game, a user found himself assigned to DNA portions linked to exudative vitreoretinopathy 4 and vesicoureteral reflux 2.

Players choose from a variety of categories such as digestive system diseases, heart diseases, brain diseases and cancer. All the DNA portions in the game are linked to different diseases. Once completed, they are analyzed and stored in a database; McGill intends to use players’ results in the game to optimize future genetic research.

This reminds me of Foldit (mentioned in my Aug. 6, 2010 posting) another multiplayer online biology-type game; that time the focus was protein folding. As Ungerleider notes in his article, gaming is being used in education, advertising, and media. I’ll add this,  it’s also being used for military training.

I was interested to note that the McGill game was made possible by these agencies,

* Natural Sciences and Engineering Research Council of Canada
* McGill School of Computer Science
* McGill Centre for Bioinformatics
* McGill Computational Structural Biology Group

On a side note, there’s another biology-type game called Phylo, it’s a trading card game designed by David Ng, a professor at the University of British Columbia. From the Phylo, trade card game About page,

What is this phylo thing? (Some interesting but relatively specific FAQs here)

Well, it’s an online initiative aimed at creating a Pokemon card type resource but with real creatures on display in full “artistic” wonder. Not only that – but we plan to have the scientific community weigh in to determine the content on such cards, as well as folks who love gaming to try and design interesting ways to use the cards. Then to top it all off, members of the teacher community will participate to see whether these cards have educational merit. Best of all, the hope is that this will all occur in a non-commercial-open-access-open-source-because-basically-this-is-good-for-you-your-children-and-your-planet sort of way.

The Phylo, trading card game is in Beta (for those not familiar with the term beta, it means the game is still being tested, so there may be ‘bugs’).

It’s nice to be able to report on some innovative Canadian crowdsourcing science.

Year of Science in the province of British Columbia

This is an initiative by the province of British Columbia announced by Premier Gordon Campbell on Sept. 24, 2010 (from the news release titled),

To inspire young minds across the province and foster a culture of research and innovation Premier Gordon Campbell today proclaimed the 2010-2011 school year as the Year of Science in B.C.

Premier Campbell was joined by Moira Stilwell, Minister of Advanced Education and Labour Market Development, schoolchildren, award-winning science students and science organizations at today’s event at Science World to officially launch the Year of Science.

“Labour market forecasts predict that by the end of this decade, three quarters of all future jobs in B.C. will need some post-secondary education, and many of the most interesting and well-paying jobs will need a solid understanding of math, sciences, engineering and technologies,” said Premier Campbell. “Through the Year of Science, working in partnership with leaders in the science community, our government wants to help B.C. families connect with the passion and exhilaration of science discovery, and call attention to some of the diverse and exciting career opportunities available through science right in their own communities.”

The Year of Science is a major cross-government initiative led by the Ministry of Advanced Education and Labour Market Development. The goal is to engage British Columbians, in particular young people, in science by showcasing how science works, who scientists are, the kinds of work they do, and why science matters in the everyday lives of British Columbians and the communities they live in.

“Science is about creative spirit and inspiration – about developing new knowledge – and the ability to turn knowledge into new and improved goods and services demanded by the global marketplace,” said Stilwell. “Through the Year of Science, we want to create a legacy that will continue to encourage a culture of innovation and research in B.C. and inspire young minds with the thrill of scientific discovery.”

The Premier unveiled phase one of the Year of Science website to provide up-to-date information about Year of Science events as the year unfolds. The site features profiles on businesses, science centres and B.C. science personalities who are shaping the face of science in B.C. Interactive games and activities will be added in October.

I checked out the Year of Science website and I’m sorry to say it looks like one of those websites that are good for you, something I call ‘spinach programming’. If I were borderline about the attractions of science, this site would not help. In fact, it might have the opposite effect intended.  Here’s sample text from the front page,

It’s important for PARENTS to encourage kids to explore the world of science.

Read more …

I don’t know how much a busy parent who’s made the effort to check out this site is going appreciate being harangued (full caps are generally considered shouting) to do more. On the optimistic side of things, it’s good to see the interest from the province and changing text from full caps to mixed case is an easy fix.

Isotopes, beverages, and nuclear isotope shortages

Nanowerk recently posted a news item about isotopes and beverages which indicates that scientists can track your geographic location because the beverages you drink leave a signature or trace  in your hair. From the news item,

The scientists analyzed isotope patterns in bottled water, soda pop, and beer from 33 cities and found that patterns in the beverages generally matched those already known for the tap water. They noted that the isotope pattern in beverages tends to vary from city to city in ways that give cities in different regions characteristic “iso-signatures.” A person who drinks a beer or soda in Denver, Des Moines, or Dallas, for instance, consumes a different isotope signature than a person in Las Cruces, Las Vegas, or Laramie. The finding may help trace the origin of drinks or help criminal investigators identify the geographic travels of crime suspects and other individuals through analysis of hair strands, the study suggests.

I think Sherlock Holmes would have liked this. On another note, for anyone (like me) who’s not quite sure what an isotope is, I found a number of definitions and this one best fits the use described in the news item,

some elements have more than one form. They differ only in nuclear terms rather than chemical ones and have different relative atomic mass as a result. They may behave slightly differently which allows us to use them in geography for a number of measurements relating to constructing past conditions. http://www.tuition.com.hk/geography/i.htm

On other isotopic fronts, Dave Bruggeman at Pasco Phronesis posted about a move by the Government of British Columbia (a Canadian province) to address the shortage of medical isotopes. There was a bit of a scandal last year when Canadians found out that the Chalk River facility which produces a fair chunk (1/3 according to this Wikipedia essay) of the global supply of  isotopes used for medical purposes was badly deteriorating.

There have been a number of problems with the facility since 2007 culminating in a shutdown in 2009 which helped to precipitate a worldwide shortage and a Canadian scandal. The Chalk River facility has yet to reopen but (from Pasco Phronesis),

… The B.C. Premier recently announced that a $63 million (Canadian) accelerator facility will be developed at the national physics lab [TRIUMF] in Vancouver (H/T Science Canada). The use of an accelerator for generating isotopes is critical, as it’s a relatively new means for doing so. It allows for a means to move away from using fission reactors for isotope generation.

Bravo Premier Campbell! Margaret Munro in her June 23, 2010 article about the initiative noted in the Vancouver Sun,

Premier Gordon Campbell, who handed over $30.7 million for the project, talked up the more down-to-earth benefits, such as helping alleviate the global medical-isotope shortage, and demonstrating that B.C. is home to “world-class ” science and groundbreaking technology.

The new accelerator promises “a new way to produce the radio isotopes needed by doctors and patients everywhere,” Campbell said.

The provincial money means construction can begin this summer on the powerful accelerator that is expected to beam Canada into the forefront of subatomic and isotope research. The Canada Foundation for Innovation has invested $18 million, and $14 million will come from core federal funding for TRIUMF.

Isotopes, used for medical scans and treatments, are now made by aging and increasingly unreliable nuclear reactors [Chalk River]. Researchers at TRIUMF are working with teams across Canada to explore new options.

This doesn’t sound like the same kind of isotope the chemists were talking about with the beverages and the discussion of geographic tracking. If I understand the difference rightly, the isotopes in the beverages are naturally occurring while these other isotopes are engineered and, I imagine, less stable. For anyone who loves definitions, here’s another one for isotopes,

an atom that has more neutrons in the nucleus than its stable counterpart. For example: Hydrogen has one electron and a nucleus containing one proton, Deuterium (an isotope of hydrogen) has one electron plus a nucleus containing one proton and one neutron. www.hiper-laser.org/glossary.asp

A few thoughts on business and nanotechnology

In my response to a comment on yesterday’s posting I was not able to address the issue of  business’ role in nanotechnology safety efforts raised by this sentence,

Parents won’t leap for joy over the suggestion that their children must be exposed to these products, lest a company’s opportunity to move forward in marketing these products for profit be stymied.

As I don’t want to be misleading, it should be noted that the commenter is critical of my stance on risk and nanosunscreens and was using this comment to buttress a more comprehensive argument.

Reading the [July 7, 2011 corrected for grammar] comment earlier today was coincidental with my discovery yesterday of an article by a business owner (Scott Rickert, President and Chief Executive Officer of Nanofilm) about the proposed nanomaterials definitions in bills before the US House of Representatives and Senate (previously mentioned on this blog here).  From Taking the NanoPulse — Toxic Substance Meets Poison Thinking; New toxics legislation aims for safe. But is it sound? (Industry Week website) where Rickert discusses the Safe Chemicals bills and nanotechnology,

… for those of us in the nanotechnology field, there’s an additional wrinkle beyond the chemical formula of our products. Both the House and Senate version of the bill now include size, size distribution, shape and surface structure in the definition of a chemical’s “substance characteristic.” That means that over and above concerns about the chemical formula a nanotechnology company may be using, it may become suspect simply because of its nanoscale charactertics.

Am I worried? No. I know the people in this industry and I believe we have a track record that shows our care at policing ourselves. We’re not monsters. We have families, children and grandchildren, too. Make no mistake, we’re concerned about environmental health and safety in our industry. [emphasis mine] We have rules and programs in place. In addition, companies like mine have been working in special new voluntary reporting programs with the EPA. And, heaven knows, our whole industry has been educating scientists, governments, special interest groups and the general public about nanotechnology for a decade or more.

I think both the commenter and Rickert are right in entirely different ways and somewhat wrong in exactly the same way. Rickert goes on,

So what’s keeping me up at night? Not worries about toxicity and nanotechnology. We can handle that. I’m worried about toxicity in the law-making process. One of the Senate authors of the Bill says, “America’s system for regulating industrial chemicals is broken… Parents are afraid because hundreds of untested chemicals are found in their children’s bodies.”

Is that really where we want to start? Throwing open the door to panic — on both sides? I sat in on a nanotechnology industry conference call recently and the fear of a “witch hunt” was palpable.

If parents are terrified, they’re in the same boat as honest, responsible companies that are making products that improve lives and have long been committed to health and environmental causes. Do you think in this age of BP oil spills and late-night law-firm mesothelioma infomercials that businesses aren’t aware that preventing a problem is better than paying for it later?

To answer Rickert’s question, I think companies are quite aware of the risks and quite willing to pass them on to consumers and citizens in pursuit of an extra dollar.  With that, I’ve agreed with the commenter and now I’m going to agree with Rickert, there are honest responsible companies run by people who care about the environment and health.

Neither the commenter nor Rickert make a distinction I want to introduce about companies/businesses. A vast gulf exists between a small to medium-sized business and a multinational enterprise in terms of revenue and economic impact, perspective on responsibility, connections to their communities, and so on. Someone who’s built up their own business in their community is quite likely to have a different take on acceptable risks than someone who lives a continent away and has no direct ongoing contact with the community in which the business is operating.

Take for example,  Tony Hayward, Group Chief Executive, BP Oil. As I write this, BP Canada (BP Oil’s Canadian subsidiary) has started work on on a well for their coalbed methane project  in an area of British Columbia (Canada) that lies between the internationally famous Banff National Park and Waterton-Glacier International Peace Park which provides a corridor for mountain-dwelling wildlife who move between the two parks. From the news item on CBC (Canadian Broadcasting Corporation) News,

As oil continues to gush from a BP wellhead in the Gulf of Mexico, critics say the company has quietly broken ground on a controversial project in B.C.’s Rocky Mountains.

Opponents of the Mist Mountain project say they were surprised to find that BP Canada, an arm of the BP group of companies, began construction earlier this month on an exploratory well for its coalbed methane project near Fernie, B.C.

But Hejdi Feick, the director of communications for BP Canada, said British Columbians can be reassured that the company is a good corporate citizen.

“We are absolutely committed to doing this right,” she said Tuesday. “We have been very open and accessible over the last three years.”

That is little comfort for [Ryland] Nelson (from the group Wildsight), who said BP had promised to consult with the public every step of the way yet he only learned construction was underway when he went to the site Monday.

Nelson said the contractor on site told him they hope to bring in drilling equipment by the end of the month and start drilling this summer.

“Here they are, they’ve been working for nearly two weeks and nobody knew anything about it,” he said.

Remarkable here is how thoroughly tone deaf the company representative is to the reception this initiative is likely to enjoy. (By the way, I live in British Columbia.)

My point is that you can’t lump all businesses together as being thoroughly unethical in the pursuit of the almighty buck nor can you lump them together as honest, ethical entities being run by people who aren’t “monsters.” (Note: I believe that Rickert was using the word to make a point about business owners being people too. I have ruthlessly extracted that word from its natural placement to suggest that while  Hayward and his ilk may or may not be monsters, the consequences of their actions in the Gulf are monstrous.)

In the discussion about nanotechnology and safety I think we need to consider as many perspectives as possible without condemning everyone who represents business interests or being unduly naïve about competing interests. I do encourage you to read Ricket’s critique of the two Safe Chemicals bills as he brings up issues that would never have occurred to me and, I imagine, others who are not directly involved in the production of nanotechnology-enabled products.

Darwin theme: Rap about Darwin & evolutionary biology and Darwinism in quantum dots

You wouldn’t expect someone with this pedigree,

… Professor of Microbial Genomics at the University of Birmingham since July 2001. … is dually qualified as a scientist (PhD) and as a medic/clinical bacteriologist (MBBS, MRCPath), and benefits from Research-Council funding for both bioinformatics and laboratory-based molecular bacteriology projects. His interests focus on bacterial pathogenesis and the exploitation of sequence data, particularly genome sequence data.

to commission a piece of rap music but that’s just what Professor Mark Pallen did last year to honour Darwin’s anniversary (150 years since the publication of Darwin’s theory and 200 years isnce his birth). He contacted Baba Brinkman, a Vancouver, Canada -based rap artist, to commission a series of raps about Darwin and evolutionary biology. The project has become The Rap Guide to Evolution. You can find more about the work at Pasco Phronesis (thank you for the pointer) which also features a number of Brinkman’s videos. There’s also a Brinkman ‘evolutionary’ video on the CBC 3 (Canadian Broadcasting Corporation) site. In that video, Brinkman spontaneously adds some lines to his rap. I don’t know if you’ve ever tried to improvise while you’re presenting for any length of time but it’s not easy and Brinkman actually manages to do this while rhyming about evolutionary biology in front of an audience that’s somewhere between 200 and 500 people (I can’t be sure of the number).

There are some places I don’t expect to see any mention of the theory of evolution and quantum theory is one of those places. From the news item on physorg.com,

Physicists have found new evidence that supports the theory of quantum Darwinism, the idea that the transition from the quantum to the classical world occurs due to a quantum form of natural selection. By explaining how the classical world emerges from the quantum world, quantum Darwinism could shed light on one of the most challenging questions in physics of the past century.

The basis of almost any theoretical quantum-to-classical transition lies in the concept of decoherence. In the quantum world, many possible quantum states “collapse” into a single state due to interactions with the environment. To quantum Darwinists, decoherence is a selection process, and the final, stable state is called a “pointer state.” Although pointer states are quantum states, they are “fit enough” to be transmitted through the environment without collapsing and can then make copies of themselves that can be observed on the macroscopic scale. Although everything in our world is quantum at its core, our classical view of the universe is ultimately determined by these pointer states.

How researchers have used quantum dots  to provide evidence of quantum Darwinism and the link from quantum physics to classical physics is covered in the rest of the news item. The researchers’ study is published here,

A.M. Burke. “Periodic Scarred States in Open Quantum Dots as Evidence of Quantum Darwinism.” Physical Review Letters 104, 176801 (2010). Doi:10.1103/PhysRevLett.104.176801
