A weakened version of the bacteria that causes cholera provides quick protection to rabbits. The vaccine may one day stop outbreaks of the deadly intestinal disease.

Stem cells that make blood cells in fish flourish in the shade provided by a newly discovered cellular “umbrella” that keeps them safe from UV damage.

Three brain development genes are found only in humans and may have helped drive the rapid expansion of the brain starting roughly three million years ago.

HHMI invests $200 million in a small cadre of leading scientists, challenging them to push the limits of what we know about biology.

Sixty-six exceptional medical and veterinary students are embarking on a year of research with support from HHMI.

Merging lattice light sheet microscopy with adaptive optics reveals the most detailed picture yet of subcellular dynamics in multicellular organisms.

The crystal structure of a G protein commonly mutated in pituitary tumors could help researchers develop anti-cancer drugs.

Scientists have engineered ferrets genetically to study abnormally small brain size in humans – and, in the process, discovered hints as to how our brains evolved.

HHMI scientists have deconstructed the brain circuits that control parenting behavior in mice and identified discrete sets of cells that control actions, motivations, and hormonal changes involved in nurturing young animals.
