Forensics specialists could use a commercially available assay to determine if a sample comes from dog, wolf, or coyote.

A new way to study ancient insect DNA relies on the "time capsule" nature of pack rat nests, which the rodents soak with urine.

DNA from a fossilized jawbone has allowed researchers to piece together the genome of one of the largest lemurs ever, which could weigh up to 350 pounds.

New research examines how DNA repair works in sperm and eggs during development. The work could shed light on treatments for cancer, infertility, and more.

Some regions of the human genome where the DNA can fold into unusual 3D structures called G-quadruplexes show signs that they are preserved by natural selection.

The plumose anenome dines on a surprising menu item: ants. A new study digs into how they became part of a marine food chain.

The closest family of the Haitian cave-rail, an extinct bird from the Caribbean, are from Africa and the South Pacific, not the Americas, a new study finds.

A blood test can predict—within a day of a hospital admission—which patients with COVID-19 are at highest risk of severe complications or death.

From slot machines to data encryption, many fields need true random numbers. Now researchers have generated them using DNA synthesis for the first time.

Darwin's theory of evolution should be expanded to include consideration of a DNA stability "energy code"—so-called "molecular Darwinism"—say scientists.
