Researchers block damage to fetal brain following maternal alcohol consumption

BETHESDA, Md. (August 11, 2008) − In a study on fetal alcohol syndrome, researchers were able to prevent the damage that alcohol causes to cells in a key area of the fetal brain by blocking acid sensitive potassium channels and preventing the acidic environment that alcohol produces. The cer...

When following the leader can lead into the jaws of death

For animals that live in social groups, and that includes humans, blindly following a leader could place them in danger. To avoid this, animals have developed simple but effective behaviour to follow where at least a few of them dare to tread rather than follow a single group member. This ...
