You could say two is a small number. But that's still two too many for one professor of exercise and sports science who has researched the topic of heat-related deaths in high school football players.

A new study in the journal Neuron indicates that microRNA may influence the development of alcohol tolerance, a hallmark of alcohol abuse and dependence.

Autopsies usually point to a cause of death but now a study of brain tissue collected during these procedures, may explain an underlying cause of major depression and suicide. Scientists found proteins that modify DNA directly are more highly expressed in the brains of people who commit suicide.

Pregnant women who binge drink early in their pregnancy increase the likelihood that their babies will be born with oral clefts.

Researchers have found new ways to kill dormant bacteria that have become seemingly resistant to antibiotics.

Scientists have found that several people in South and Southeast Asian countries working and living around monkeys have been infected with simian foamy virus, a primate virus that, to date, has not been shown to cause human disease. The findings provide more evidence that Asia, where interaction between people and monkeys is common and widespread, could be an important setting for future primate-to-human viral transmission.

A maternal history of Alzheimer's disease appears to predispose individuals to the mind-robbing disease because their brains aren't using glucose efficiently, according to new findings.

Staying awake slows down our brains, scientists have long recognized. Mental performance is at its peak after sleep but inevitably trends downward throughout the day, and sleep deprivation only worsens these effects. For the first time, researchers have found a way to stop this downward slide in fruit flies.

Two hormone-like compounds linked to the consumption of soy-based foods can cause irreversible changes in the structure of the brain, resulting in early-onset puberty and symptoms of advanced menopause, according to a new study. The study is a breakthrough in determining how these compounds can cause reproductive health problems, as well as in providing a key building block for how to treat these problems.

Low levels of naturally occurring antibodies may represent an increased risk of developing cardiovascular disease, particularly stroke in men. This discovery, published in the academic journal Atherosclerosis, has now led to attempts to develop an immunization against cardiovascular disease.
