Spring is coming earlier to parts of the Arctic, and so are some migratory birds. But researchers have yet to get a clear picture of how climate change is transforming tundra life. That's starting to change as automated tools for tracking birds and other animals in remote places come online, giving researchers an earful of...
Gene-edited pigs are resistant to billion dollar virus
Scientists have produced pigs that can resist one of the world's most costly animal diseases, by changing their genetic code.
Tests with the virus -- called Porcine Reproductive and Respiratory Syndrome, or PRRS -- found the pigs do not become infected at all.
The animals show no signs that the change in their DNA has had any...
T. Rex couldn't stick out its tongue
Dinosaurs are often depicted as fierce creatures, baring their teeth, with tongues wildly stretching from their mouths like giant, deranged lizards. But new research reveals a major problem with this classic image: Dinosaurs couldn't stick out their tongues like lizards. Instead, their tongues were probably rooted to the bottoms of their mouths in a manner...
Fossils show ancient primates had grooming claws as well as nails
Humans and other primates are outliers among mammals for having nails instead of claws. But how, when and why we transitioned from claws to nails has been an evolutionary head-scratcher.
Now, new fossil evidence shows that ancient primates -- including one of the oldest known, Teilhardina brandti -- had specialized grooming claws as well as nails....
Dogs understand what's written all over your face

People who feel threatened by vegetarianism more likely to care less about animals
New research suggests that if people perceive the rise of vegetarianism as a threat to their way of life they are more likely to care less for some animals.
Researchers from the University of Kent in the UK and Brock University in Canada studied the impact of human supremacy beliefs and vegetarianism on whether people feel...
