| Fall of Communism changed mathematics in US Posted: 07 Feb 2012 05:28 PM PST The collapse of the Soviet Union in 1992 brought an influx of Soviet mathematicians to US institutions, and those scholars' differing areas of specialization have changed the way math is studied and taught in this country, according to new research.  |
| Scientists develop biological computer to encrypt and decipher images Posted: 07 Feb 2012 05:28 PM PST Scientists have developed a "biological computer" made entirely from biomolecules that is capable of deciphering images encrypted on DNA chips.  |
| Mars Express radar yields strong evidence of ocean that once covered part of Red Planet Posted: 07 Feb 2012 12:18 PM PST ESA's Mars Express has returned strong evidence for an ocean once covering part of Mars. Using radar, it has detected sediments reminiscent of an ocean floor within the boundaries of previously identified, ancient shorelines on Mars.  |
| Innovation promises expanded roles for microsensors Posted: 07 Feb 2012 10:37 AM PST Researchers have learned how to improve the performance of sensors that use tiny vibrating microcantilevers to detect chemical and biological agents for applications from national security to food processing.  |
| A bronze Russian doll: The metal in the metal in the metal Posted: 07 Feb 2012 10:37 AM PST Just like in the Russian wooden toy, a hull of 12 copper atoms encases a single tin atom. This hull is, in turn, enveloped by 20 further tin atoms. Scientists have now generated these spatial structures built up in three layers as isolated metal clusters in alloys. With their large surfaces these structures can serve as highly efficient catalysts.  |
| Scientists 'record' magnetic breakthrough Posted: 07 Feb 2012 10:35 AM PST Scientists have demonstrated a revolutionary new way of magnetic recording which will allow information to be processed hundreds of times faster than by current hard drive technology.  |
| Engineers boost computer processor performance by over 20 percent Posted: 07 Feb 2012 06:55 AM PST Researchers have developed a new technique that allows graphics processing units (GPUs) and central processing units (CPUs) on a single chip to collaborate – boosting processor performance by an average of more than 20 percent.  |
| Nanorod-assembled order affects diffusion rate and direction Posted: 06 Feb 2012 09:26 AM PST Scientists studied the movements of a spherical probe amongst static nanorods. They found that the particles sometimes diffused faster in a nematic environment than in a disordered environment. That is, the channels left open between the ordered nanorods don't just steer nanoparticles along a direction, they also enable them to speed right through.  |
| The butterfly effect in nanotech medical diagnostics Posted: 06 Feb 2012 09:26 AM PST Tiny metallic nanoparticles that shimmer in the light like the scales on a butterfly's wing are set to become the color-change components of a revolutionary new approach to point-of-care medical diagnostics, according to a new study.  |
| Materials for first optical fibers with high-speed electronic function are developed Posted: 05 Feb 2012 01:37 PM PST For the first time, researchers have developed crystalline materials that allow an optical fiber to have integrated, high-speed electronic functions. The potential applications of such optical fibers include improved telecommunications and other hybrid optical and electronic technologies, improved laser technology, and more-accurate remote-sensing devices.  |
