Ancient DNA from a hunter-gatherer skeleton points to earlier-than-expected human arrivals on Southeast Asian islands known as Wallacea.
Some of the exclusively human tweaks to DNA may have played a role in brain evolution.
A study pinpoints a key mutation that may have put a bat coronavirus on the path to becoming a human pathogen, helping it better infect human cells.
By tweaking just three genes in a common lab plant, scientists have discovered the mechanism responsible for one of nature’s most impressive fractals.
A study of 45,000 people links 13 genetic variants to higher COVID-19 risks, including a link between blood type and infection and a newfound tie between FOXP4 and severe disease.
A new study suggests that the biological age of both mouse and human embryos resets during development.
The distinctive coloring and skin tumors of a type of gecko called Lemon Frost have been pegged to a gene implicated in human skin cancer.
DNA suggests little-studied Chinese mountain cats have been rendezvousing with pet cats on the Qinghai-Tibetan Plateau since the 1950s.
Light-activated proteins inserted in eye nerve cells and special goggles help the man, who lost his sight due to retinitis pigmentosa, see objects.
DNA has four building blocks: A, C, T and G. But some bacteriophages swap A for Z, and scientists have figured out how and why they do it.
