An anonymous reader writes "The Empathic Systems Project a Northwestern University demonstrate up to 50% power savings by controlling CPU frequency scaling based upon the end user. They measure the user with eye trackers, galvanic skin response, and force sensors to find a CPU frequency that the user is satisfied with. They are currently studying user activity and system performance on mobile architectures, specifically the Android G1 phone."

Scientists Create RNA From Primordial Soup 369

Kristina at Science News writes "The RNA world hypothesis proposed 40 years ago suggested that life on Earth started not with DNA but with RNA. Now a team of scientists bolsters this hypothesis, having assembled RNA in the lab from a mixture that resembles what was likely the primordial soup. 'Until now,' Science News reports, 'scientists couldn't figure out the chemical reactions that created the earliest RNA molecules.' The new work started the RNA assembly chemistry from a different angle than what earlier work had tried."
