A 20-foot-long crocodile with three sets of fangs — like wild boar tusks — roamed parts of northern Africa millions of years ago, researchers reported Thursday. While this fearsome creature hunted meat, not far away another newly found type of croc with a wide, flat snout like a pancake was fishing for food.
The snows of Kilimanjaro may soon be gone. The African mountain's white peak — made famous by writer Ernest Hemingway — is rapidly melting, researchers report.
A single dose of the swine flu vaccine works well for almost all pregnant women, but young children will still need two doses for best results, federal health officials said Monday.
Global warming is messing with the planet's thermostat.
The price of first-class stamps will not go up next year.
The story of humankind is reaching back another million years as scientists learn more about "Ardi," a hominid who lived 4.4 million years ago in what is now Ethiopia. The 110-pound, 4-foot female roamed forests a million years before the famous Lucy, long studied as the earliest skeleton of a human ancestor.
Don Ho was right. It is the tiny bubbles. A team of researchers — in Europe not surprisingly — found that Champagne's bursting bubbles not only tickle the nose, they create a mist that wafts the aroma to the drinker.
Millions of Monarch butterflies migrate to Mexico for the winter and scientists have long speculated on how the insects find their way. Turns out, their antennas are the key.
For the first time, the famed and feared Hope Diamond is on display au naturel.
About 125 million years ago a tiny version of Tyrannosaurus rex roamed what is now northeastern China. Tiny, that is, by T. rex standards — you still wouldn't want to meet it face to face.
In what may be the scariest shower news since Alfred Hitchcock's "Psycho," a study says showerheads can harbor tiny bacteria that come spraying into your face when you wash. People with normal immune systems have little to fear, but these microbes could be a concern for folks with cystic fibrosis or AIDS, people who are undergoing cancer treatment or those who have had a recent organ transplant.
Arctic warming is affecting plants, birds, animals and insects as ice melts and the growing season changes, scientists report in a new review of the many impacts climate change is having on the far north.
More than 30,000 years ago someone living in a cave in the Caucasus Mountains twisted wild flax together and dyed it, producing the earliest known fibers made by humans, scientists report.
The Arctic is warmer than it's been in 2,000 years, even though it should be cooling because of changes in the Earth's orbit that cause the region to get less direct sunlight. Indeed, the Arctic had been cooling for nearly two millennia before reversing course in the last century and starting to warm as human activities added greenhouse gases to the atmosphere.
The Postal Service has narrowed the number of offices facing possible closure to 413.
From short to shaggy, nearly all the differences in dogs' coat types result from variations in just three genes, according to researchers studying how genes work together.
Women with more testosterone tend to behave more like men when taking financial risks, according to a new study. "Women with higher levels of testosterone turn out to be less risk averse, more willing to take risks," Luigi Zingales of the University of Chicago said in a telephone interview.
The people who multitask the most are the ones who are worst at it. That's the surprising conclusion of researchers at Stanford University, who found multitaskers are more easily distracted and less able to ignore irrelevant information than people who do less multitasking.
Thousands of feet beneath the sea live worms that can cast off green glowing body parts, a move scientists think may be a defensive effort to confuse attackers. Researchers have dubbed the newly discovered critters "green bombers."
The Hope Diamond is going bare to celebrate a half-century at the Smithsonian.
Maybe it was an accident or perhaps an ancient experiment. Many thousands of years ago, early humans somehow figured out they could make better stone tools by treating the rocks with fire. Evidence of that, dating 72,000 years ago, has been found on the southeastern tip of Africa, researchers report in Friday's edition of the journal Science.
Looking for ways to boost business, the Postal Service is planning to offer discounts to some of its best customers.
The local post office long has been the center of many American communities, but with people turning increasingly to the Internet to send messages and pay bills, financial losses are forcing the Postal Service to consider consolidating or closing hundreds of local facilities.
Scientists say they may have tracked down the origins of the deadly disease malaria — chimpanzees.
A pillar of U.S. communities since the nation's founding, the post office is facing the prospect of closings or consolidation of services at hundreds of locations amid a sharp decline in business due to e-mail.
