A graduate student sequenced rats all over Manhattan, and discovered how the city affects their genetic diversity.

New research casts doubt on a gene-editing strategy that scientists had hoped to use against invasive species and epidemic diseases.

Tobias the Labrador retriever has been trained to sniff out invasive Argentine ants wherever they hide, which could help preserve fragile ecosystems.

Owners are increasingly interested in their pets’ intelligence, giving researchers eager recruits in the relatively new field of canine cognition.

A bird group named the Vegaviidae, which resembled modern loons and geese, is the first identified with members that lived before and after the Cretaceous extinction

Raccoons are notoriously pesky, but are they as clever as a crow? Scientists recently put the masked mammals through the Aesop's Fable test, which measures if animals can discern cause and effect by displacing water to access food. The experiment is based on the story in which a thirsty crow can’t drink from a pitcher with a low level of water. By dropping in stones, the bird raises the water level and is able to drink.

Crows share an interesting set of behaviors with humans: they like to play, and they often use tools. We know that humans play to learn. When toddlers knock over a pile of blocks, they're developing the ability to build and measure objects in the real world. The question is, do crows play for the same reason? An international team of cognitive scientists played with some crows to find out. What they discovered gives us a new understanding of crow consciousness, but it still leaves a lot of questions unanswered.

Our dogs really are trying to tell us something with a pout, smile or big pleading eyes, say researchers.

Featuring two decades of new evidence on dog evolution, behavior, training, and human interaction

Tom Vaughan, a photographer then living in Colorado’s Mancos Valley, kept a hummingbird feeder outside his house. One morning, he stepped through the portico door and noticed a black-chinned hummingbird dangling from the side of the red plastic feeder like a stray Christmas ornament.

Canines don’t seem to perceive their reflections in mirrors. But they do better with a ‘smell mirror.’

Barn owls keep their acute sense of hearing into old age, scientists have discovered.

The classic self-recognition test gets a makeover for dogs, using smell not sight

We know that dinosaurs ruled the Earth many millions ago, but how they walked has been a mystery. Our new research shows that the movement of some dinosaurs has a lot in common with some of today’s ground-dwelling birds. We looked at theropod dinosaurs, which were typically bipedal (two-legged), walking on their hind legs like Tyrannosaurus rex.

However, despite his exclusively herbivorous diet, surprisingly the giant panda has a typical carnivorous gastrointestinal tract, anatomically similar to dog, cat or raccoon, with a simple stomach, a degenerated caecum and a very short colo

No experience with human speech is necessary for budgerigars to perceive the difference between "d" and "t", according to a study published May 31, 2017 in the open-access journal PLOS ONE by Mary Flaherty from The State University of New York, Buffalo, USA, and colleagues.

We're still making many discoveries about the animals that roamed the Earth more than 66 million years ago, and a newly identified dinosaur bears a remarkable resemblance to a modern-day bird, the cassowary .

DNA analyses of tardigrades has given scientists an insight into their incredible survival abilities.

Watch the amazing way this little frog gives his tadpoles the ultimate safe haven to grow up in.

This is quite a good lecture with a number of interesting insights into domestication.
