By analyzing the DNA found in 1,000-year-old mummies, scientists found evidence that sea mammals were the first to bring tuberculosis to the Americas.
A new study finds cancer affects even simple, ancient multicellular organisms — which means the disease and the deaths it causes may simply be a part of life.
A coffee entrepreneur claims his brew is different — and better — than the trendy civet poop coffee. And it starts with the idea that elephants, unlike humans or civets, are herbivores.
The EPA wants to "clarify" the scope of its oversight of water under the Clean Water Act. Big farm groups like the American Farm Bureau Federation call this a power grab that would place every ditch and mud puddle under federal regulation, forcing farmers to get permits for small trenches around the farm.
Long summer days in Alaska help cabbages, turnips and other vegetables grow to gargantuan sizes. These "giants" are celebrated at the annual state fair, which kicks off on Thursday.
There's a link between how children draw at age 4 and how well they perform on intelligence tests at age 14, researchers say.
Suppose two Chinese parents get on an Australian airplane and, while flying over U.S. territory, they have a baby on the plane. Can that baby be an American citizen?
The type of Ebola erupting in West Africa is closely related to one found 2,500 miles away — the distance between Boston and San Francisco. How did the virus spread so far without anyone noticing?
Across the U.S., jails hold many more people with serious mental illness than state hospitals do. San Antonio is reweaving its safety net for the mentally ill — and saving $10 million annually.
Using a new technology, scientists have created a vaccine for an emerging mosquito-borne virus. The vaccine was safe and produced some degree of immunity in a preliminary study.
A recent study tried to pin down just how many elephants have been killed by poachers. It's a lot — enough to eventually eliminate the species — but pinning down an exact death toll is difficult. The reason elephants are so hard to protect is the same that makes them so hard to count: They roam — exceptionally far.
