Long spaceflight causes structural changes in the brain

Spending long periods in space not only leads to muscle atrophy and reductions in bone density, it also has lasting effects on the brain. However, little is known about how different tissues of the brain react to exposure to microgravity, and it remains unclear whether and to what extent the neuroanatomical changes so far observed persist following return to normal gravity.

Study suggests new strategy to kill melanoma cells

Think of the protein BH3 like a finger that turns off a cancer cell survival switch. The problem is that most cancer cells have found ways to remove this "finger" - commonly, by breaking the action of a gene called p53 that puts the BH3 finger in motion. Now think of Bcl-2 as the switch itself.
