Scientists have called the rise of the tiger population into question by pointing out flaws in a method that's common used in censuses of tigers.
Scientists are learning a bit more about abrupt climate shifts. They examined African lake sediments from the past 20,000 years in order to advance their understanding of current changing weather patterns and what we might expect in the future.
Greenland is melting, so what does this mean for the future? In order to find out, a team of scientists looked to the past and quantified how the Greenland Ice Sheet reacted to a warm period that occurred 8,000 to 5,000 years ago.
Scientists have uncovered an entirely new species of seadragon. While researching two known species of seadragons in an effort to understand and protect these fish, researchers uncovered a third, unknown species.
Coral reefs may not be in such dire straits as researchers once thought. Scientists have found that corals may be better equipped to tolerate climate change than previously believed.
The bottlenose dolphin didn't always live in the Mediterranean. Scientists have found that this charismatic marine mammal only moved to the region after the last Ice Age, about 18,000 years ago.
Scientists have uncovered a new trend in evolution. They've found that animals tend to get larger over time.
The human brain has expanded dramatically over the course of our evolution. But how did the human brain get so big? Now, scientists have taken a closer look and have found a genetic code in humans that can enlarge mouse brains.
Scientists have found that in the coming decades, at least one-quarter of the world's wheat production will be lost to extreme weather from climate change if no adaptive measures are taken.
There may be some good news for tigers. Conservationists have caught a family of rare tigers on film deep inside China, more than 65 years after the species was largely wiped out in the country.
Trash enters our world's oceans in unprecedented amounts each year. Now, though, researchers have taken a closer look at the impact of manmade debris on marine species.
Scientists have taken a closer look at some of the most effective predators in the ocean: white sharks. Now, they've found that these animals grow far more slowly and mature much later than previously thought, which could have implications for conservation efforts.
