Infant mice given genistein developed cancer of the uterus later in life. Data suggest that genistein is carcinogenic if exposure occurs during critical periods in a young animal's develpment.
Ritalin and other stimulants have become the standard treatment for ADHD in elementary-age children because of their ability to curb disruptive and defiant behavior. Now, a new study finds that Ritalin also improves daily academic performance and behavior of teenagers.
Mexican Americans are less likely to recognize the risk factors of stroke, to call 9-1-1 for stroke, or know that effective stroke therapy exists -- significant barriers to both stroke treatment and prevention.
For the first time, stress has been linked to increased stroke risk in a population study of middle-aged white men.

The world sounds very different to infants than it does to adults, sometimes being filled with a cacophony of sounds that makes it diffcult for babies to distinguish a single sound. That's because babies are generalists and hear all frequencies simultaneously, says a University of Washington researcher.
