Google glass to hit developers’ hands this month
January 16, 2013

google_io2012_glasses   Developers who want to get their hands on Google’s Project Glass won’t have to wait much longer, Mashable reports. Google announced plans Tuesday to hold a “Glass Foundry” in San Francisco and New York in the coming weeks: Two full days of hacking that will allow developers to get an early look at Glass and … more…


Using an electron beam to manipulate nanoparticles
January 16, 2013

How to trap a gold nanoparticle in an environmental cell: an electron beam passes through a silicon nitride window and grabs the nanoparticle (credit: Haimei Zheng et al./Lawrence Berkeley National Laboratory)   Scientists from Berkeley Lab and the National University of Singapore have developed a way to manipulate nanoparticles using an electron beam. They used an electron beam from a transmission electron microscope to trap gold nanoparticles and direct their movement, and to assemble several nanoparticles into a tight cluster. They also imaged the nanoparticles as they … more…


Intelligent molecules
January 16, 2013

Solvent-induced collapse of an environmentally responsive copolymer (attached to a gold surface and an atomic force microscope tip). The molecule changes length in response to increased salt concentration. (Credit: Michael A. Nash, and Hermann E. Gaub/ACS Nano)   It sounds like science fiction: “intelligent molecules” that react to external stimuli and reversibly change their shape. But now Ludwig-Maximilians-Universität (LMU) physicists have succeeded for the first time in creating a chemical reaction, using a single polymer molecule, that makes this process visible. Dr. Michael Nash and his colleagues placed a self-generated synthesized polymer on a … more…


Asteroid deflection mission seeks smashing ideas
January 16, 2013

AIDA_mission_concept_node_full_image   A space rock several hundred meters across is heading towards our planet and the last-ditch attempt to avert a disaster — an untested mission to deflect it — fails. This fictional scene of films and novels could well be a reality one day. So the European Space Agency (ESA) is appealing for research ideas to … more…


Building electronics bottom-up
January 16, 2013

Nanodots of iron oxide were laid out in a highly ordered pattern without the use of templates. The average diameter of the particles was 25 nanometers, with regular spacing of 45 nm. (Credit: Christopher G. Hardy et al./University of South Carolina)   University of South Carolina’s Chuanbing Tang is out to turn the microelectronics industry upside down. Currently, modern electronics are primarily fabricated by etching the smooth surface of a starting material — say, a wafer of silicon, using micro- or nanolithography to establish a pattern on it. This top-down method might involve a prefabricated template, such as … more…


To make open access work, we need to do more than liberate journal articles
January 16, 2013

reading_book   In the days since the tragedy of Aaron Swartz’s suicide, many academics have been posting open-access PDFs of their research as an act of solidarity with Swartz’s crusade to liberate (in most cases publicly funded) knowledge for all to read. While this has been a noteworthy gesture, the problem of open access isn’t just about … more…

The best tribute to Aaron Swartz
January 15, 2013 by Giulio Prisco

AaronSwartzPIPA   If you are a scientist, you can pay the best and most effective tribute to the memory of Aaron Swartz by sharing PDFs of your published work on pdftribute.net via the hashtag #pdftribute on Twitter. Researchers are now offering open-access versions of their work using this hashtag. I also suggest to boycott the pay-walled journals of the … more…

Subliminal: How Your Unconscious Mind Rules Your Behavior
author Leonard Mlodinow

Leonard Mlodinow, the best-selling author of The Drunkard’s Walk and coauthor of The Grand Design (with Stephen Hawking), gives us a startling and eye-opening examination of how the unconscious mind shapes our experience of the world and how, for instance, we often misperceive our relationships with family, friends, and business associates, misunderstand the reasons for our investment decisions, and … more…
