The science behind total recall: New player in brain function and memory

Posted: 13 Nov 2014 12:29 PM PST

Is it possible to change the amount of information the brain can store? Maybe, according to a new international study. The research has identified a molecule that puts a brake on brain processing and when removed, brain function and memory recall is improved.

Bacteria become 'genomic tape recorders', recording chemical exposures in their DNA

Is there organic matter on Mars? Chloromethane not due to contamination from Earth, research suggests

Posted: 13 Nov 2014 08:00 AM PST

Organic matter recently detected by NASA's robotic rover Curiosity is probably not due to contamination brought from Earth as researchers originally thought. A team of German and British scientists now suggests that the gaseous chlorinated organic compound -- chloromethane -- recently found on the Red Planet most likely comes from the soil of Mars, with its carbon and hydrogen probably deriving from meteorites that fell on the planet's surface.

Did men evolve navigation skill to find mates? Spatial ability, roaming distance linked to number of lovers
