Depression is common enough -- afflicting one in ten adults in the United States -- that it seems the possibility of depression must be "hard-wired" into our brains. This has led biologists to propose several theories to account for how depression, or behaviors linked to it, can somehow offer an evolutionary advantage. Some previous proposals for the role of depression in evolution have focused on how it affects behavior in a social context. A pair of psychiatrists addresses this puzzle in a different way, tying together depression and resistance to infection. They propose that genetic variations that promote depression arose during evolution because they helped our ancestors fight infection. read more..

Hiv Criminalization-Hiv Exposure-HIV
Housing Works: "A decade ago, not a single African country had a law that specifically criminalized HIV exposure. Now, at least 27 African nations punish exposure.

But by using vague and imprecise language in its HIV criminalization statute it also creates fear, confusion and the further stigmatization of people living with HIV.” read more..

Blockade
Neuroscientists have shown that an enzyme overproduced in the brains of Alzheimer's patients creates a blockade that shuts off genes necessary to form new memories. Furthermore, by inhibiting that enzyme in mice, the researchers were able to reverse Alzheimer's symptoms. read more..
