A new view of visual system development

Researchers at Duke University have discovered that spontaneous neural activity plays a key role in organizing the visual cortex, contradicting current theories on ocular dominance. The study used young ferrets with closed eyes to record brain activity patterns and found that input from one eye drives the entire system.

Two scientists make case against ice on the moon

Two Stanford University scientists argue that large amounts of water ice are unlikely on the Moon, suggesting an alternative explanation involving the reaction of lunar dust with hydrogen and oxygen. They propose that the Lunar Prospector crash could produce a plume of water vapor and hydroxyl ions without ice being present.
