Participatory science; wearable batteries; radio interview with Andrew Maynard; shadow science ministers in Canada’s political parties

Ordinary people (nonscientists like me) have a long tradition of participating in scientific research in areas such as astronomy and ornithology (bird watching). A local example is the eagle count which takes place at Brackendale every year. (Aside: The 2010 count has already taken place but it’s still possible to attend festival events which are now part of the Brackendale eagle count experience.)

Someone whose science interests may be more esoteric can have trouble finding opportunities to pursue their interests. Thanks to the Science Cheerleader there is a new online resource to help you find a project. From the Science Cheerleader blog,

Hot diggity-DOG! After years in the making, my partner, Michael Gold, and I–with generous support from Science House–have officially unveiled the beta version (that means this is still a work-in-progress) of ScienceForCitizens.net . Science journalist, Carl Zimmer, who frequently writes for Discover and Time Magazine, said “It’s like Amazon.com for all sorts of possibilities for doing cool citizen science”. We’ll take that

And thanks to the Pasco Phronesis blog for the info. about the Science Cheerleader.

For an abrupt change of pace: Yes, you could be wearing your batteries at some point in the future. Scientists at Stanford University (CA) have found a way to easily and inexpensively turn cotton or polyester fibres into batteries or, as they call it, wearable energy textiles or e-textiles. From the news item on BBC News,

“Wearable electronics represent a developing new class of materials… which allow for many applications and designs previously impossible with traditional electronics technologies,” the authors [of the study published in ACS Nano Letters] wrote.

A number of research efforts in recent years have shown the possibility of electronics that can be built on flexible and even transparent surfaces – leading to the often-touted “roll-up display”.

However, the integration of electronics into textiles has presented different challenges, in particular developing approaches that work with ordinary fabrics.

Now, Yi Cui and his team at Stanford University in the US has shown that their “ink” made of carbon nanotubes – cylinders of carbon just billionths of a metre across – can serve as a dye that can simply and cheaply turn a t-shirt into an “e-shirt”.

I’ve taken a look at the research paper which, as these things go, is pretty readable. Bravo to the American Chemical Society (ACS) for not placing the material behind a paywall. The article, Stretchable, Porous and Conductive Energy Textiles,  published in the ACS journal Nano Letters is here.

I had the pleasure of listening to a radio interview on Whyy Radio conducted by Marty Moss-Coane where she interviewed Dr. Andrew Maynard, Chief Science Advisor for the Project on Emerging Nanotechnolgies. The interview (approximately 50 mins.)  titled, The Science and Safety of Nanotechnology, is available for listening here. Moss-Coane was well-prepared, asked good questions, and had listeners call in with their own questions. Dr. Andrew Maynard was, as always, very likable and interesting.

After my recent posting on science policy in Canada and the four major political parties, I thought I’d check out the various shadow science ministers or critics. Here’s what I found,

Gary Goodyear, Conservative, Minister of State (Science and Technology)

Jim Maloway, NDP, Science and Technology [portfolio]

Frances Coates, Green Party, shadow minister Science and Technology

Marc Garneau, Liberal Party, Industry, Science and Technology critic

I have looked at all their websites and Garneau seems the most interested in science and technology issues. Given that he’s a former astronaut and is an engineer, one might expect that he would have a major interest in the subject. He’s written a paper on the subject (thanks to the folks at The Black Hole for finding it). If you go here and either read or scroll to the bottom, you will find a link to his paper. He also has a poll on his website, What is the importance of science and technology to create the jobs for tomorrow? You can go here to answer the question. As for the others, Goodyear lists a series of announcements in news releases as accomplishments which makes identifying his actual accomplishments difficult. Jim Maloway does not mention science on his website and Frances Coates posted a few times on her blog in 2008 but made no mention of science.
