Low-cost sensor for cystic fibrosis diagnosis based on citrate
Penn State biomaterials scientists have developed a new, inexpensive method for detecting salt concentrations in sweat or other bodily fluids. The fluorescent sensor, derived from citric acid molecules, is highly sensitive and highly selective for chloride, the key diagnostic marker in cystic fibrosis.
Foliage display may suffer in parts of Pa. due to drought conditions

First accurate simulation of a virus invading a cell
For the first time, scientists know what happens to a virus' shape when it invades a host cell, thanks to an experiment by researchers at Penn State College of Medicine and University of Pittsburgh School of Medicine. Understanding how the virus shape changes could lead to more effective anti-viral therapies.
