Computer scientists suggest new spin on origins of evolvability: Competition to survive not necessary? Posted: 26 Apr 2013 08:56 AM PDT Scientists have long observed that species seem to have become increasingly capable of evolving in response to changes in the environment. But computer science researchers now say that the popular explanation of competition to survive in nature may not actually be necessary for evolvability to increase.

Movement of pyrrole molecules defy 'classical' physics Posted: 26 Apr 2013 08:54 AM PDT Quantum laws loom ever larger in physical world as new research finds quantum phenomena in effect on a molecular level.

Astronomer studies far-off worlds through 'characterization by proxy' Posted: 26 Apr 2013 08:46 AM PDT An astronomer is using Earth's interstellar neighbors to learn the nature of certain stars too far away to be directly measured or observed, and the planets they may host.

Racing car with electric drive Posted: 26 Apr 2013 04:37 AM PDT Drive technology has an electric future – of this research scientists are in no doubt. Scientists have developed an electric racing car with a novel solution for battery management and electronic sensor systems.

Engineers generate world-record mmWave output power from nanoscale CMOS Posted: 25 Apr 2013 06:11 AM PDT Electrical engineers have generated a record amount of power output —- by a power of five —- using silicon-based nanoscale CMOS (complementary metal oxide semiconductor) technology for millimeter-wave power amplifiers. Power amplifiers are used in communications and sensor systems to boost power levels for reliable transmission of signals over long distances as required by the given application.

Materials: Two ways to tame a radical Posted: 24 Apr 2013 07:23 PM PDT Trapping free electrons with polycyclic aromatic molecules creates materials with enhanced optical, electronic and magnetic properties.

Microelectronics: Taking the heat off microfluidic chips Posted: 24 Apr 2013 07:23 PM PDT Replacing a high-temperature processing technique with an infrared treatment allows the manufacture of tiny devices without damaging the polymer components.
