New science shows that teenagers today are less likely to have been exposed to cold sores growing up and therefore may be more vulnerable to genital herpes when they become sexually active.
Move over, anti-aging cream. Researchers have found a new biological clock in human DNA that determines the rate at which bodily tissues age—revealing some surprising things about which parts of our bodies feel the brunt of aging soonest, and how such aging may eventually be reversed.
Eucalyptus trees in the Australian outback sometimes contain gold particles that can indicate untapped deposits.
Sleep doesn’t just clear your head. Scientists now say it literally flushes out waste and toxins that build up in your brain during the day.
How often do you eat or drink out of a plastic container?
