Scientists transferred light-harvesting proteins into yeast for the first time, shining a light on the past lives of eukaryotic cells.

Some species of lizards, grasshoppers, and crustaceans have adopted a ladies-only lifestyle.

Researchers made the find using an algorithm that purportedly distinguishes between mutations that were selected for and those that came along for the ride by coincidence, a feat that has long eluded scientists.

Scientists around the world investigate how bat immune systems cope with viral attacks and how this information could be used to keep humans safe.

With the help of directed evolution, scientists inch closer to developing viral vectors that can cross the human blood-brain barrier to deliver gene therapy.

Evidence is mounting that epigenetic marks on DNA can influence future generations in a variety of ways. But how such phenomena might affect large-scale evolutionary processes is hotly debated.

The genomes of living animals are littered with DNA from long-gone relatives, providing a lens on evolution, past extinctions, and perhaps even solutions to agricultural problems.

By combining two innovative approaches, researchers can now sequence the full spectrum of mutational differences between individual cells’ genomes.

Bettas were likely the first fish welcomed into human homes. Now, scientists are welcoming them into the lab to learn how genes dictate their appearance and behavior.
