New research sheds light the bond between dogs and people. "We note a clear link between the movement of people and the introduction of a new type of dogs."

New research indicates rapid evolution in some great ape Y chromosomes, but not others. The scientists wonder if mating habits are why.

"It's extremely challenging to image the forces of a living cell at a high resolution." Scientists compare their luminescent DNA method to fireflies.

Researchers say DNA from stone tools from in a Mexican cave suggests humans first arrived in America about 15,000 years earlier than previously thought.

Sequencing the gardenia genome shows how plants evolved to re-use tricks from their genetic toolbox to create new chemicals.

A new system called DORIS fixes one major problem with making DNA data storage widespread, including letting users "delete" data as well as store it.

A study with chickens from Tibet shows that organisms have a kind of "memory" of their ancestral homes that makes adaptation to environmental change easier.

A tiny jelly-bean shaped organism—the most common in the ocean—may thrive because of an ability to host viruses in its DNA.

With modification a PARP inhibitor drug that's struggled in clinical trials kills cancer much more effectively, researchers say.
