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.
A warming climate may just change northern forests. Scientists have found that in the coming decades, we'll probably see a very different set of trees due to climbing temperatures.
Extreme weather phenomena called atmospheric rivers may be behind the intense snowstorms that were recorded in 2009 and 2011 in East Antarctica.
Scientists are taking a closer look at silk-weaving ants, and have made a discovery that may change our understanding of how all creatures work together. Researchers have found that the insects could evolve and abandon and then re-evolve the practice of building nests from silk.
It looks as if picky eaters may be going hungry if climate change continues. Scientists have found two species responding very differently to a changing world, and their main difference happens to lie in what they eat.
It's a bit hard to tell exactly what this new species is. Discovered in Cambodia's Cadamom Mountains, the slimy, stringy creature could easily be mistaken for a big worm or even a snake. Well, turns out, it's neither. It's actually a legless amphibian.
