In a vast, unprecedented experiment, scientists showcase evolution in real time, as predation from owls and hawks selects for genetic variations in mice that boost survival.

Vale, an HHMI investigator at the University of California, San Francisco, will serve as the second executive director of the Ashburn, Virginia-based biomedical research center. 

Until now, researchers haven’t been able to accurately quantify a latent form of HIV that persists in patients’ immune cells. A new genetic technique is fast and 10 to 100 times more accurate than previous diagnostics.

In a new Nature World View column, David Asai, HHMI's senior director for science education, explains that laboratory heads need training, support, and accountability to connect people across cultures.

A powerful new technique combines expansion microscopy with lattice light-sheet microscopy for nanoscale imaging of fly and mouse neuronal circuits and their molecular constituents that’s roughly 1,000 times faster than other methods.

Using a technique that involves analyzing thousands of single cells, scientists have figured out a new way to capture a stem cell that underlies flatworm regeneration.

Scientists have found DNA evidence for the southward migration of the people who spread the so-called Clovis culture of North America. But starting about 9,000 years ago, these people were replaced by a distinct population.

Scientists have successfully determined high-resolution structures of several small molecules using a technique called MicroED.

Janelia and Allen Institute scientists team up, combining genetic analyses, anatomical maps, and detailed studies of neuronal activity to reveal brain cells’ roles in controlling movement.
