report promising results from a small clinical trial of an SSRI drug to lower
amyloid beta levels, but years of further tests lie ahead.

much should we enhance our brains, how far should we go to treat risky pre-term
pregnancies, and when can we morally do research on people having surgery for
something else were among the topics at the William Safire Seminar on

Reducing fat levels in obese mice through exercise or surgery appears to result in better cognitive performance.

from programs like Experience Corps suggest that having a goal or purpose helps
protect against cognitive decline as we age.

many “normal” people—students, lawyers, doctors—are taking drugs that may
enhance cognitive function, there is little research into how these drugs
affect non-disordered brains. A research review suggests that using
cognitive-enhancing drugs may have unintended and quite negative consequences,
especially in youngsters.

Scientists have reported promising rejuvenation experiments on mouse brains-but it isn't clear that such results can be translated usefully into human therapies.

New policy for US National Institutes of Health funding will require that researchers propose studies that have balance of male and female cells, tissues, or animals.

that researchers have the technology to test the hypothesis that myelin is a
simple, regular axonal insulator, they find it isn’t true. Now the fun begins.

published in the past few years suggests that longer years of formal study can
strengthen the brain, making it more resistant to the ravages of old age—and
perhaps mitigating the damage that occurs after traumatic brain injury.

The loss of the REST protein from neurons appears to be an important early event in neurodegenerative disease. Researchers now are looking for ways to restore it in the elderly.

Either as “handmaidens to
neurons” or as actors in their own right, researchers find glial cells show
powerful effects in mouse models of disease.

Using DTI, researchers find brain "biomarkers" that identify who has the at-risk variation of a gene for a late onset fragile X-associated syndrome. Others are using PET scanning to track the plaques associated with Alzheimer's years before symptoms show.

investigating the gene that directs the building of protein BDNF find that
people with one variation seem to recover more slowly and less well than those
with other variations.

glycation end-products from high-temperature cooking have already been linked
to diabetes and heart disease, and scientists are now looking at their effects
on the brain.
