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.

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.
