Scientists stunned by surface of asteroid Vesta

August 2, 2011 10:02 am | by Alicia Chang, AP Science Writer | News | Comments

Last month, NASA's Dawn spacecraft began orbiting the 330-mile-wide rocky body of Vesta, the asteroid belt’s second-largest resident. The latest photos have been full of surprises, revealing extensive features, from multiple craters to mysterious grooves, that will keep scientists busy for years.

Laser writing transforms graphite into a supercapacitor

August 2, 2011 9:55 am | News | Comments

Graphite oxide has been a target for supercapacitor development for up to a decade, but prior to a recent breakthrough at Rice University nobody had been able to turn the material into a functional supercapacitor without adding chemicals. The researchers discovered a new phenomenon of GO, and were able to make the transition simply using heat.

Study: Emissions from hydroelectric reservoirs overestimated

August 2, 2011 9:47 am | News | Comments

An international team of scientists has amassed the largest data set to date on greenhouse gas emissions from hydroelectric reservoirs. Prior studies cautioned that these reservoirs could be a significant and large source of both carbon dioxide and methane to the atmosphere, but the new study claims the real output is just a fraction of previous estimates.

August 2011 Issue of R&D Magazine

August 1, 2011 1:25 pm | Digital Editions | Comments

This month's issue focuses on microscopy. Despite competition, the light microscope remains the most important instrument in the laboratory. And it's quickly evolving. The issue also looks at how companies are changing the way they organize their R&D functions and train staff for imaging applications and how confocal Raman imaging expands the possibilities for measuring large-scale samples. Other features include information on how simulation tools can answer design questions and take some of the mystery and risk out of R&D and how analysts focus on publication and citation data to reveal the size and structure of materials science research globally.

Google buys about 1,000 IBM patents

August 1, 2011 12:32 pm | by Peter Svensson, AP Technology Writer | News | Comments

After losing out to a consortium of technology companies during bidding for thousands of patents from the bankrupt Nortel, Google has bolstered its war chest with a collection of patents from IBM, one of the industry’s leading generators of intellectual property. The move has less to do with innovation than it does an effort to defend against lawsuits from other tech companies.
