Researchers developed a method to study ancient human DNA preserved by head lice.

A high-quality genome sequence for this versatile insect will likely aid eco-evolutionary research.

What triggers type 1 diabetes has been difficult to prove, but a bacterium that produces an insulin-like peptide can give mice type 1 diabetes, and infection with the microbe seems to predict the onset of the disease in humans.

Frogs invest in cognitive capacity to avoid predators—up until there are too many hungry snakes around for the evolutionary strategy to pay off.

An in situ map of copy number variations in prostate tissue reveals that purportedly cancerous genomic changes frequently occur in the healthy tissue surrounding tumors.

To understand the mechanisms behind severe COVID-19, researchers identified common COVID-19 genetic risk variants that affect immune cell function.

Low-intensity electrical stimulation allows older adults to better recall a list of words for at least a month following the treatment, a study finds, providing further evidence for the debated idea that electrical stimulation can enhance cognitive performance.

Milk fortifiers of human origin show no evident advantage in the development of the gut microbiota of premature infants over fortifiers derived from cows, while the intake of the mother’s own milk does, two studies suggest.

The 81-year-old director says that he will step back from his positions this December, but that he will continue working to advance science and public health.

Pet dogs produce a larger volume of tears when they are reunited with their owners than with acquaintances, possibly because of surging oxytocin levels—findings that could be the first evidence of emotional crying in nonhuman animals.

Tortoise leaf beetles enjoy the protection the fungus provides from insect predators such as ants, then carry the microbe to a mutual plant host, which their fungal symbiont infects.

Troves of sequencing data reveal genes tied to autism through different variant types, providing a more complete picture of the condition’s genetic roots and new clues to its heterogeneity.
