Penn State will join a new international collaboration to develop detection hardware and algorithms for remote monitoring of nuclear reactors.

Mechanical Force Controls Speed of Protein Synthesis
Assistant professor of chemistry Edward O'Brien.

Proteins power many of a cell's vital functions, and gaining a better understanding of their synthesis could help fight numerous diseases.

Improving Photonic Technology Used Across Industries

Cheaper and more efficient photonic devices, such as lasers, optical fibers, and other light sources, may be possible with confined light.

Finding the proteins that unpack DNA
DNA is typically wrapped tightly around proteins called histones (colored) to form a nucleosome, a structure that condenses DNA strands to fit in a cell’s nucleus. A new method allows scientists to identify specialized proteins called nucleosome-displacing factors that unwrap these nucleosomes, making the usually dense DNA more accessible for gene expression and other functions.
