In Peru, legend tells of Incan warriors who were forbidden to eat a powerful sex herb after conquering a city. The herb, called maca, was such a potent aphrodisiac that it was feared the warriors who ate it would be tempted to ravage women. Today, some 2,000 years after maca was first cultivated in Peru, researchers are studying whether maca can help men and women with a low libido.

Docs seek to better ID concussions' 'invisible injury'
It is hardly a comforting sight when an athlete's body lies splayed and twisted on the field after an injury. Doctors can splint a broken arm or X-ray a twisted knee. But when a concussion occurs, diagnosis is not so simple. "The athletes don't appear injured," said Dr. Jeffrey Kutcher, assistant professor at Michigan NeuroSport at the University of Michigan. "Concussion is an invisible injury in a lot of cases, therefore there is no awareness of the injury."

Why party animals are always sleepy
Do your personality and social life say something about the way you sleep? According to a new study in the journal Sleep, patterns of sleep can be based on the kind of social activities we partake in, and the type of people we are. The study results showed that people who were outgoing, or extroverts, who were exposed to 12 hours of social interaction, were more vulnerable to being sleepy than those extroverts who participated in 12 hours of isolated activity. Response tests showed that extroverts who had great social lives were slower in the early hours of the day, as well as noon time, compared with extroverts who were by themselves. For those who were less outgoing, or the introverts, their response tests were unaffected and remained stable no matter what their activities. |
