The Princeton University evolutionary biologist studies how animals are changing due to human activity.

Humanity was hoping to emerge from the COVID-19 pandemic this year. But viruses have plenty of tools at their disposal, and we should plan for a long-term future in which SARS-CoV-2 is a persistent threat.

By studying the vocal behavior of 20 baby bats from birth to weaning, researchers have identified striking similarities between how young humans and bats develop communication skills.

Researchers found the relatively high proportion of DNA from a hominin cousin—nearly 5 percent—when they scanned more than 1,000 genomes from 118 distinct ethnic groups.

Spores found in 480 million-year-old rock bring the fossil record in line with molecular estimates of when plants first adapted to life on land.

A newly identified gene family named “parasitoid killing factor” is found in both insect-infecting viruses and their hosts, although researchers can’t yet tell where they originated.

Spontaneous waves of nerve impulses flowing across the retina help mouse pups practice motion detection for when they eventually open their eyes.

Massive extrachromosomal elements named after the hive-minded cyborg villains in Star Trek may be the first of their kind.
