Some late-life depression is likely to be caused by narrowing and hardening of the brain arteries rather than any chemical or emotional imbalance, reports research in the Journal of Neurology, Neurosurgery and Psychiatry.

Infections may trigger autoimmunity via rare, but normal process
Autoimmune disorders, such as lupus, arthritis, and diabetes, are understood to result from breakdowns in the sophisticated safeguards that prevent the immune system from turning its destructive power against the body's own cells.

Potent new compound from blue-green algae may help treat, elucidate nerve disorders
Researchers have discovered a compound in blue-green algae that could help provide a better understanding of nerve function, which could someday lead to new treatments for pain, epilepsy and possibly stroke.

Carbon cycling and species composition: seeing the forest for its trees
One of the most contentious debates during the recent climate talks in Hague centered on the possible use of forests as credit towards reducing atmospheric carbon dioxide.

A new and unique model incorporates biological factors into studies of the effects of climate change on ecologies.

Handheld cellular telephone use not associated with risk of brain cancer
The use of handheld cellular telephones does not appear to be associated with the risk of brain cancer, but further studies are needed to account for longer induction periods, especially for slow-growing tumors, according to an article in the December 20 issue of The Journal of the American Medical Association (JAMA).

A new way for cells to die
Discovery sheds new light on Alzheimer's and related diseases Buck Institute scientists describe an alternative form of programmed cell death, which they dub

Diffusion MRI shown to give early signs of cancer's response to treatment
A new use for a widely available MRI technique may soon help doctors assess the effectiveness of cancer therapy without relying on measurable changes in tumor size, potentially sparing patients the psychological anxiety of waiting weeks to see if their treatment works, and the agonizing physical effects of ineffective therapy.
