Unzipped Nanotubes Unlock Potential for Batteries
June 14, 2013 12:51 pm | by Mike Williams, Rice University | News | CommentsResearchers at Rice University have come up with a new way to boost the efficiency of the ubiquitous lithium ion battery by employing ribbons of graphene that start as carbon nanotubes. Proof-of-concept anodes — the part of the battery that stores lithium ions — built with graphene nanoribbons and tin oxide showed an initial capacity better than the theoretical capacity of tin oxide alone, according to James Tour.
Nanoparticle Opens the Door to Clean-Energy Alternatives
June 14, 2013 12:41 pm | by Katrina Voss, Penn State | News | CommentsCheaper clean-energy technologies could be made possible thanks to a new discovery. Led by Raymond Schaak, a professor of chemistry at Penn State University, research team members have found that an important chemical reaction that generates hydrogen from water is effectively triggered -- or catalyzed -- by a nanoparticle composed of nickel and phosphorus, two inexpensive elements that are abundant on Earth.

Court Ruling May Open Up Breast Cancer Gene Tests
June 14, 2013 10:02 am | by Marilynn Marchione, AP Chief Medical Writer | News | CommentsA ruling by the Supreme Court that human genes can't be patented is expected to increase access and drop the cost for tests for gene mutations that greatly raise the risk of developing breast or ovarian cancer. In a bit of a mixed message, the court unanimously decided that certain types of gene tests may still be protected by patents, yet it struck down patents that a company has long held for BRCA genes.
New Array Measures Vibrations Across Skin May Help Engineers Design Tactile Displays
June 14, 2013 9:45 am | by Jennifer Chu, MIT News Office | News | CommentsIn the near future, a buzz in your belt or a pulse from your jacket may give you instructions on how to navigate your surroundings. Think of it as tactile Morse code: vibrations from a wearable, GPS-linked device that tell you to turn right or left, or stop, depending on the pattern of pulses you feel.
