The Sloan Kettering researcher used mutagenic screening to probe genes and molecular pathways, including Toll and Hedgehog, essential to development in fruit flies and mice.

Their ability to distinguish between individuals is strong evidence for fast mapping, a learning tool generally thought to belong only to humans.

Enhancers, short regions of DNA that direct gene expression, of species separated by 700 million years of evolution worked interchangeably, according to a new study.

Researchers turn to familiar model animals, along with some fresh strategies, to develop countermeasures against SARS-CoV-2 and investigate the biology of infection.

The scientific community said goodbye to Sydney Brenner, Paul Greengard, Patricia Bath, and a number of other leading researchers this year.

Organisms with unusual genomes are helping scientists investigate gene regulation, evolution, and development.

Fly avatars bearing multiple genetic changes akin to those of a cancer patient lead to a tailor-made treatment that has shrunk the patient’s tumors.

An unusual population of immune cells appears to exist in zebrafish as well as mammals.
