Brain Research: New treatments for Alzheimer's ♦ Risk-takers are smarter, according to a new study ♦ Reduced blood flow in brain after recovery from concussion

Synapse discovery could lead to new treatments for Alzheimer's disease A team of scientists has discovered how connections between brain cells are destroyed in the early stages of Alzheimer's disease -- work that opens up a new avenue for research on possible treatments for the degenerative brain condition

Could fish have consciousness? 'Emotional fever' experiment suggests they might Researchers have observed an increase in body temperature of between two and four degrees in zebrafish, when these are subjected to stressful situations.
