We may just be a bit closer to the end of the world. Scientists have moved the hand of the symbolic Doomsday Clock two minutes closer to midnight, citing unchecked climate change and the threat of nuclear weapons as the reason.
An Arctic ice cap may be sliding into the ocean. Satellite images have revealed that the ice cap has thinned by more than 50 meters since 2012, which is about one sixth of its original thickness, and is now flowing 25 times faster.
Australia's Great Barrier Reef is one of the natural wonders of the world. Now, though, scientists have found that this reef could decline to less than 10 percent of its extent if ocean warming continues.
It turns out that our ancient human ancestors used their hands like we do. Scientists have discovered that pre-Homo human ancestral species, such as Australopithecus africanus used human-like hand postures far earlier than expected.
It looks like something that shouldn't exist outside of someone's nightmare: the frilled shark. This prehistoric-looking creature can be found in the deep ocean and is rarely seen near the surface. Now, though, a fishing trawler off Australia's coast has caught one of these rare sharks.
Whale sharks are some of the largest living fish in the world and now, they may be getting a little help. The Inter-American Tropical Tuna Commission (IATTC) adopted a resolution that prohibits the placement of a purse seine net around whale sharks.
What caused the extinction of the dinosaurs? Scientists have long thought that an asteroid might have helped but now, new research has debunked the theory that a massive impact also caused vast global firestorms that led to a global mass extinction.
Scientists are learning a bit more about the ecosystems thriving beneath Antarctic ice. Using a hot-water drill and an underwater robotic vehicle, researchers have made some new discoveries about Antarctica's geology and biology.
Dramatic habitat loss could threaten the population of the world's most endangered chimp subspecies. Scientists have found that by 2020, these chimps may face extinction.
Scientists have made a surprising discovery beneath the Greenland Ice Sheet. While building the highest-resolution map yet of this ice sheet, they found two lakes of meltwater that pooled beneath the ice and rapidly drained away.
When it comes to genetically modified organisms, testing is crucial. Because they're biological, it's important to contain them both physically and genetically. Now, scientists have created a method to cause genetically modified biological organisms to die if released from the lab into the "wild."
Scientists may have discovered a new species of predator crocodile that actually preceded the dinosaurs. They've uncovered a new species called Nundasuchus, a nine-foot-long carnivorous reptile with steak knifelike teeth.
