Penn Study in Fruitflies Connects Protein Misfolding, Sleep Loss and Age

Pulling an “all-nighter” before a big test is practically a rite of passage in college. Usually, it’s no problem: You stay up all night, take the test, and then crash, rapidly catching up on lost sleep. But as we age, sleep patterns change, and our ability to recoup lost sleep diminishes.

Penn-Designed ‘Swiss Army Knife’ Molecule Captures RNA From Single Cells

A multi-disciplinary team from the University of Pennsylvania has published in Nature Methods a first-of-its-kind way to isolate RNA from live cells in their natural tissue microenvironment without damaging nearby cells. This allows the researchers to analyze how cell-to-cell chemical connections influence individual cell function and overall protein production.

Penn Medicine: Red Blood Cells Take on Many-Sided Shape During Clotting

Red blood cells are the body’s true shape shifters, perhaps the most malleable of all cell types, transforming – among many other forms -- into compressed discs capable of going through capillaries with diameters smaller than the blood cell itself. While studying how blood clots contract John W.
