Since the discovery of the satiety factor leptin, it has been clear that fat should be regarded not solely as a storage site for lipids, but also as an endocrine tissue.

Saw palmetto can improve symptoms for men with urinary problems
A six-month-long carefully controlled study by physicians at the University of Chicago provides the best evidence to date that the herbal remedy saw palmetto can improve symptoms for men with lower urinary tract problems, but that it has no significant impact on urinary flow rates, quality of life, or sexual function.

Novel device takes over where leeches leave off
A new device improves on the centuries-old medicinal use of leeches and avoids the unpleasantness of having a blood-sucking parasite attached to your body.

Nearly a quarter of the estimated 4 million women who give birth each year in the United States receive an antibiotic during labor in order to protect their infants from developing a serious infection.

New computer system beats humans at guessing gender from face and voice cues
A new computer classification system developed by Penn State computer scientists can correctly identify a person's gender - based only on eyes, nose, mouth and voice cues - better than human beings can.
