RNA molecule behind behavior changes cued by environment

Quick changes in behavior – in worms, at least – can be triggered by a unique form of the molecule RNA acting within the nucleus of a cell, UC San Francisco researchers have discovered.

Researchers discover species-recognition system in fruit flies

A team led by UC San Francisco researchers has discovered a sensory system in the foreleg of the fruit fly that tells male flies whether a potential mate is from a different species. The work addresses a central problem in ...

Gene invaders are stymied by a cell's genome defense

Gene wars rage inside our cells, with invading DNA regularly threatening to subvert our human blueprint. Now, building on Nobel-Prize-winning findings, UC San Francisco researchers have discovered a molecular machine that ...

Commercial space travel carries implications for health

(Phys.org)—Just a half-century after the first human ventured into space, commercial space travel—or "space tourism"—is quickly becoming a reality. A new UCSF study looks at the health implications of flying into outer ...

Glowing zebrafish shed light on metabolism

A tiny, translucent zebrafish that glows green when its liver makes glucose has helped an international team of researchers identify a compound that regulates whole-body metabolism and appears to protect obese mice from signs ...
