French cyclists were caught using EPO in the 1998 Tour de France; Olympic officials began testing athletes at the Sydney Games...

While maternal stress can trigger physiological events that might affect fetal development, the exact mechanism is not clear.

Researchers believe that bereavement causes a decline in natural immunity, while a handful of studies suggest the trauma following a disaster may trigger a small immune boost...

Moderates counter that conservative voters are already motivated and that Republicans should be more worried that pushing a gay-marriage amendment will turn off the more vital swing voters.
