If babies imitated everything they saw and heard, you certainly wouldn't want them hanging out with other babies; the whole lot would reinforce each other's worst behavior and unintelligible babbling. No, what you want is for the kid to imitate the speech...

I kind of doubt that Lonesome George, the giant Galápagos tortoise who geneticists believe is the last survivor of his species will view this as good news for his social life, but conservationists are ecstatic. No, they have not found another member of...

Autism spectrum disorder now affects an estimated 1 out of every 150 people in the U.S., compared to fewer than 1 in 1,000 a decade or so ago. There is huge controversy over whether that increase is real or an artifact of reporting--that is, with autism...

It has been a staple of pro-life ad campaigns and even state law: that abortion raises the risk of *** cancer and that a woman who is considering terminating a pregnancy be told that. At least three states have such "right to know" laws on their books,...

And people thought we were the ones who should be insulted at the idea of being descended from apelike ancestors, as science concluded 150 years ago. Those who object to having a monkey for an uncle regularly harrumph that humans are so much more evolved...

Like every discussion about weather and climate, this one has to be preceded by the standard disclaimer "that no particular weather event can be attributed to the global climate change that's underway as a result of the greenhouse effect. But to tell...

This has got to be the smartest protozoan on earth. Toxoplasma gondii , a parasite that infects hundreds of millions of people (an estimated 50 million in the U.S.), has a genome that's only 80,000 units long compared to humans' 3 billion, and certainly...

And the answer is: like chicken. With a hint of frog and notes of newt. It's not that many people have been asking what Tyrannosaurus rex tasted like. But in a feat that demolishes longstanding beliefs about how long biological molecules can resist the...

In the interest of collegiality, we're not going to name names, but what is it with journalists and hormones? No, I mean the kind that women take to relieve symptoms of menopause and that they were not-so-long-ago told to take to prevent heart disease....

Memo to men: keep a lid on the neuroticism as you get older. That's the message of a study to be published in May, in which scientists tracked 1,663 men in the Veterans Administration health system starting in 1988, when they ranged from 43 to 91 years...
