Polarized light waves spin clockwise or counterclockwise as they travel, with one direction behaving differently than the other as it interacts with molecules. This directionality, called chirality or handedness, could provide a way to identify and sort specific molecules for use in biomedicine applications, but researchers have had limited control over the direction of the waves — until now.
Sulfur-based compounds produced in our bodies help fight inflammation and create new blood vessels, among other responsibilities, but the compounds are delicate and break down easily, making them difficult to study. A team led by Penn State scientists have developed a new method to generate the compounds — called polysulfides — inside of cells, and the work could potentially lead to advances in wound treatment and tissue repair.
Penn State astronomers awarded two grants to develop, fabricate and test improved diffraction optics that could allow next-generation space telescopes to explore objects that are fainter and farther away in the universe

Mauricio Terrones, Evan Pugh University Professor and Verne M. Willaman Professor of Physics, and professor of chemistry and of material science and engineering, has been named the new George A. and Margaret M. Downsbrough Head of the Department of Physics at Penn State, effective July 1. Terrones succeeds Nitin Samarth, who has served as head of the department since 2011.

UNIVERSITY PARK, Pa. — A soldier suffers a serious gunshot wound on a remote battlefield or a machinist has a work accident and gets stuck in traffic on the way to the hospital. Secondary, uncontrolled bleeding from traumatic injury is the leading cause of death of Americans from ages one to 46.

UNIVERSITY PARK, Pa. — Cellulose nanocrystals — bio-based nanomaterials derived from natural resources such as plant cellulose — are valuable for their use in water treatment, packaging, tissue engineering, electronics, antibacterial coatings and much more. Though the materials provide a sustainable alternative to non-bio-based materials, transporting them in liquid taxes industrial infrastructures and leads to environmental impacts.

UNIVERSITY PARK, Pa. — From a distance, they looked like clouds of dust. Yet, the swarm of microrobots in author Michael Crichton’s bestseller “Prey” was self-organized. It acted with rudimentary intelligence, learning, evolving and communicating with itself to grow more powerful.
