Scientists discover how fat triggers a gut-to-brain mechanism that drives us to keep consuming more of it. Their findings could one day lead to interventions to help treat obesity and associated disorders.

Analyzing DNA from the remains of hundreds of ancient humans across West Asia, the Balkans, Greece, present-day Turkey, and other regions, scientists have revealed surprising migrations that illuminate human history and led to the languages billions of people speak today.

Blanton Tolbert, a biochemist and administrative leader of diversity, equity, and inclusion efforts at Case Western Reserve University, will serve as an HHMI vice president and head of the Institute’s new Center for Science Leadership and Culture.

Some people and animals grow arteries that allow blood to bypass blockages in the heart. But to engineer these bypasses to serve as lifelines, scientists first need to understand how they work. Researchers have now modeled blood flow through small vessels surrounding the heart.

HHMI announces the selection of 25 exceptional early career scientists as 2022 Hanna Gray Fellows. The 2023 Hanna H. Gray Fellows Program competition is now open for applications.

The blood-dining insect’s neural circuitry for sniffing out its chosen prey is far more complicated and sophisticated than previously thought.

The large viruses known as jumbo phages employ a curious counter-defense strategy to protect their DNA while attacking bacteria. Now, scientists have identified the key protein involved and solved its structure.

Fifty-one graduate students and their advisers are joining the thriving community supported by the HHMI Gilliam Fellowships for Advanced Study.

To test their DNA typewriter, scientists sought to hide well-known phrases inside cells. But this invention’s most powerful application may lie in documenting the biological events that unfold within the boundaries of normal and diseased cells.
