Music By Natural Selection 164

maccallr writes "The DarwinTunes experiment needs you! Using an evolutionary algorithm and the ears of you the general public, we've been evolving a four bar loop that started out as pretty dismal primordial auditory soup and now after >27k ratings and 200 generations is sounding pretty good. Given that the only ingredients are sine waves, we're impressed. We got some coverage in the New Scientist CultureLab blog but now things have gone quiet and we'd really appreciate some Slashdotter idle time. We recently upped the maximum 'genome size' and we think that the music is already benefiting from the change."

Submission + - 18 year old scales Mount Everest

Deeply_Pipelined writes: From Earth's tallest point, the message was understandably breathless. "We made it to the top!" Samantha Larson told her mother via satellite phone Thursday after reaching the summit of Mt. Everest. "Now all we have to do is make it back down." Larson, 18, of Long Beach, became one of the youngest people to scale the 29,035-foot peak, reaching the summit with a group that included her father, David Larson, 51, an anesthesiologist at Long Beach Memorial Medical Center. The honors graduate of Long Beach Polytechnic High School put off her start as a freshman at Stanford by a year to scale some of the world's highest mountains.

Submission + - Device Uses Solar Energy to Convert Carbon Dioxide

jnguy writes: reports that Scientist at University of California, San Diego have developed a device that can capture sun light, convert it to electrical energy and turn carbon dioxide into carbon monoxide and oxygen. Millions of pounds of carbon monoxide are used every year to manufacture chemicals such as detergents and plastics. Carbon monoxide can also be converted into liquid fuel. Not only does the device provide energy, but it also reduces greenhouse gas. The device is not yet optimized, as it requires an external source of energy. University of California also has a press release. The research is supported by the Department of Energy
