Climate change threatens to shake up the lifestyles of many animals around the world and a new study involving GPS-tagged birds has revealed that for the American robin these wheels are already very much in motion.

Scientists in Finland have conducted a study investigating the root causes of fearfulness in dogs, uncovering a previously unknown link between urban living environments and social fearfulness in dogs.

Made famous in the movie Jurassic Park, the raptor dinosaurs are scientifically known as the dromaeosaurids. A newly-discovered member has recently been added the group, and it was likely one of the last raptors to exist.

It's already a well-known fact that on average, women live longer than men. A European study now indicates that the difference between male and female lifespans is even more pronounced in other types of mammals.

When it comes to human interactions with venomous snakes, we tend to think of that venom as something that was "designed" mainly for defense. A new study, however, suggests that it evolved first and foremost as a means of killing prey.

Tree rings hold clues to the plant's past – and your own teeth might do the same. Scientists have found that the material in the roots of teeth preserves a lifelong record of stresses on the body, such as childbirth, illness, and even prison time.

Scientists have already observed that rats will readily share food with other rats who are hungry. A new study now suggests that they do so not just based on what the other rat does, but also on how it smells.

If you've ever thought that you got food poisoning from eating sushi, you might have actually gotten worms from the stuff. A new study indicates that such fish worms are now more common than ever – although chefs usually pick them out.

It turns out that there still are new things under the sun – or in this case, under the water. Scientists have recently discovered not one but two previously-unknown species of the six-gill sawshark, which is itself rarely seen.

Hands were one of the key things fish needed to evolve before moving out of the water and becoming tetrapods like us, and a new fossil study pinpoints a "missing link" in the evolutionary tree. Meet Elpistostege, from nearly 400 million years ago.

If you're wondering what the weather was like thousand of years ago, well … there aren't going to be weather reports from back then. What there are, however, are fossilized giant clam shells, and a new study suggests they could provide the answers.

It is well known that dogs boast an incredible sense of smell, but new research has uncovered another way our four-legged friends use their famous noses to find their way around, detecting radiant heat much like a thermal infrared sensor.
