Authors of the new study theorize that the actual effects of testosterone, a hormone produced by the male testes and female ovaries that is linked to brain development and sexual behavior, may be somewhat neutral in nature, leading to what researchers call "status-seeking behavior." Under certain conditions, status-seeking could lead to increased aggression - in prison populations, for instance, where studies have shown that inmates in high-security prisons have elevated levels of the hormone - when fighting seems the only way to the top.

...cases of autism. Working with the Autism Genetic Resource Exchange - a DNA database of more than 2,000 families affected by autism, and the largest genetic study of the disorder ever attempted - researchers zeroed in on variations in genes that code for proteins involved in forming connections in the brain. Differences in these particular genes are extremely common - present in more than half of healthy people - but they are even more common in people with autism, affecting 65%.

...genes linked to the late-onset form of the disease, the type that hits people in their 60s or later and accounts for 90% of Alzheimer's cases in the U.S. Two of the genes are known to interact with the amyloid-protein plaques that build up in the brain of Alzheimer's patients and eventually cause nerve-cell death and cognitive problems. The third affects the junction of nerve cells, where various neurochemicals work to relay signals from one nerve cell to another. It's not clear yet exactly how the genes increase Alzheimer's risk - in fact, most...
