So-called 'sandfish' could help materials handling and process technology specialists
It moves as quickly in sand as a fish moves through water, which is why this lizard, a species of skink (Scincus scincus) that grows to about 15 cm long and lives in the deserts of North Africa and the Near East, is commonly known by the name "sandfish."   view more (2008-10-03)

Direct recording shows brain signal persists even in dreamless sleep
Neuroscientists at Washington University School of Medicine in St. Louis have taken one of the first direct looks at one of the human brain's most fundamental "foundations": a brain signal that never switches off and may support many cognitive functions.   view more (2008-10-01)

Caltech scientists find cells coordinate gene activity with FM bursts
