President Barack Obama will ask Americans to think of climate change as a threat not just to the environment, but also to their health.
Hydrothermal vents on a Saturn moon are so similar to life-ridden hydrothermal vents on Earth, scientists think they may find life up there, says a report in Nature.
It's not just people who love the food in New York City. So do certain ants.
Researchers at the University of California, San Diego Skaggs School of Pharmacy and Pharmaceutical Sciences used information collected from hundreds of skin swabs to produce three-dimensional maps of molecular and microbial variations across the body.
The report studied more than 3,500 known plant species and determined that 22 percent are considered rare, in decline, endangered or possibly extinct.
Two particularly hungry, exotic termite species apparently have found love halfway around the world and, as with so many other Florida hook-ups, the results are disturbing.
A herd of 14 wild mares from Britain's Exmoor National Park were moved in January to the former Milovice military base, 35 kilometers (22 miles) northeast of Prague, the Czech capital.
The species grew up to two meters (six feet) in length and lived in lakes and rivers.
On an East African hill somewhere in “Afar,” a stone’s throw from “Awash,” two sections of a large detached jawbone grinned brokenly at Ethiopian Arizona State University (ASU) graduate student Chalachew Seyoum. The pieces were just lying there, so the student picked them up and brought them together. They fit “perfectly,” he said.
Could a changing climate and changing environments have an impact on the spread of infectious diseases? At least one zoologist thinks so.
Prenatal exposure to low doses of the environmental contaminants polychlorinated biphenyls, or PCBs, change the developing brain in an area involved in metabolism, and some effects are apparent even two generations later, a new study finds.
When salmon, salamanders or other aquatic animals poop or shed skin cells, they leave behind traces of their DNA in the water, like clues left behind at a crime scene.
Optical features embedded in marine shells may help develop responsive, transparent displays.
Earth's past, present and future come together here on the northern peninsula of Antarctica, the wildest, most desolate and mysterious of its continents.
Contaminated medical instruments are suspected in a "superbug" outbreak at a Los Angeles hospital that has infected at least seven patients, two of whom died. More than 170 others may have been exposed to the antibiotic-resistant bacteria.
At least 5 mass extinction events have profoundly changed the history of life on Earth. But a new study led by researchers at the University of Gothenburg shows that plants have been very resilient to those events.
A tiny minnow that lives only in backwaters in Oregon's Willamette Valley is the first fish to be formally removed from Endangered Species Act protection because it is no longer in danger of extinction.
Australia is funding a three-year, 2.3 million Australian dollar ($1.8 million) project that will aid snakebite victims in Myanmar by upgrading care facilities and the quality and availability of antivenom.
Beavers don’t brush their teeth, and they don’t drink fluoridated water, but a new study reports beavers do have protection against tooth decay built into the chemical structure of their teeth.
Nearly 200 pilot whales stranded themselves on New Zealand's South Island on Friday, and hordes of rescuers rushed to the remote area in a bid to guide them back to sea.
Humans aren’t the only species to be influenced by spin. Our closest primate relatives are susceptible, too.
A plateau on the Arctic Ocean floor, where thousands of Pacific walrus gather to feed and raise pups, has received new protections from the Obama administration that recognize it as a biological hot spot and mark it off-limits to future oil drilling.
Most of the genetic mutations that cause cancer result from environmental ‘damage’ (for example, through smoking or as a result of over-exposure to sunlight) or from spontaneous errors as cells divide.
Whenever an endangered animal dies at the San Diego Zoo, researchers race out, regardless of the hour, to remove its sperm or eggs, maybe a bit of ear or eyeball, and carefully freeze the cells in liquid nitrogen.
In the social world, people constantly gather information through visual cues that are used to evaluate others and interact. A new study from researchers at the University of Missouri determined that babies can make sense of complex social situations, and that they expect people to behave appropriately.
