An analysis of the genomes of people from 50 ethnolinguistic groups in Africa spots 62 genes under positive selection and 3 million more genetic variants than previously documented.

Analyses of more than 300 ancient human genomes show that Hepatitis B virus has infected humans for at least 4,500 years and has much older origins than modern viral genomes would suggest.

A new study reveals how Neanderthal DNA in the genomes of present-day British people influences their traits.

Emerging infections provide clues about how pathogens might evolve when farm animals are protected from infection.

Tracking the myxoma virus in the wild rabbit populations of Australia has yielded insight into how pathogens and their hosts evolve.

Biologists’ walk in the woods sparks the creation of a masterful fruit fly field guide. 

A genomic analysis of “Klosneuviruses” suggests that they evolved from small viruses that accumulated genetic material over time, but not all virologists are convinced. 

Researchers discover that short pieces of DNA harboring oncogenes are relatively widespread in cancer.
