Polina Lishko, PhD, a BJC Investigator and professor of cell biology and physiology at WashU Medicine All mammals share a particular protein embedded in the surface of sperm called CatSper.

“That hyperactive state in sperm is key for successful fertilization, and no one knew exactly how temperature triggers it,” said Polina Lishko, PhD, professor of cell biology and physiology at WashU ...

Researchers from the Washington University School of Medicine have discovered that sperm cells contain a molecular “thermostat” that activates when temperatures rise too high. The finding solves a ...

Part spoof and part serious, the film is about mythmaking as much as it is about music. The result is delightfully destabilizing. By Alissa Wilkinson During every scene of this western, I couldn ...
