"Bullet to the Head" is an adrenaline shot to your movie memory if the blunt, gleefully dumb, no-nonsense ways of '80s-style action flicks are your nostalgia drug of choice. Mayhem mavens Sylvester Stallone and director Walter Hill ("48 Hrs. ") make their debut as collaborators on this New Orleans shoot-'em-up, based on a graphic novel about a double-crossed hit man named Jimmy Bobo (Stallone) teaming with a young, idealistic cop (Sung Kang) to investigate a murder.

Widely used DHEA supplements and testosterone patches failed to deliver their touted anti-aging benefits in one of the first rigorous studies to test such claims in older men and women.

Sreekumaran Nair of the Mayo Clinic, lead author of the study, published in Thursday's New England Journal of Medicine.

Tests of male hormone levels in women's blood cannot predict diminished sexual function and should not be used in deciding on a course of treatment, Australian researchers report today.

A woman's tears can be a total turnoff for a guy ? if he smells them, that is. Men who sniffed the tears of weeping women produced less testosterone and found female faces less arousing, according to new research that suggests a novel evolutionary explanation for why humans cry. Communication isn't limited to language, said neuroscientist Noam Sobel of the Weizmann Institute of Science in Rehovot, Israel, whose study was published online Thursday...
