At least that's what scientists have concluded from a long-term study of more than 600 men in the Philippines.

The scientists found that single men who started out with relatively high testosterone levels were more likely than other men to become fathers. But once a baby arrived, testosterone levels plummeted.

Scientists say they have figured out how a very clever virus outwits a very hungry caterpillar.

The caterpillar is the gypsy moth in its larval stage, and the invasive species damages roughly a million acres of forest in the U.S. each year by devouring tree leaves.

But the damage would be greater if it weren't for something called a baculovirus that can infect these caterpillars and cause them to engage in reckless, even suicidal behavior, scientists say. The virus is so effective that the government actually sprays it on trees to help control gypsy moth outbreaks.
