Torn ligaments and tendons are the bane of athletes and runners, difficult to heal and often taking months or years of rehab. Currently, the only fix for severe tears is to remove intact ligaments and tendons from another part of a patient’s body, or from a cadaver, and use them to repair a knee or ankle.

Commercial planes burn hundreds of gallons of jet fuel per hour of flight, which can be costly for both airlines and the environment. But if planes were made of carbon fiber-reinforced plastic (CFRP) instead of the heavier material aluminum, they could go greater distances with less fuel.
Researchers in the Penn State College of Engineering have teamed up to investigate a new, low-cost CFRP manufacturing method with a $595,000 grant from the U.S. Office of Naval Research.

With elongated bodies, large eyes and a combination of arms and tentacles, squid appear alien. In reality, they are one of the oldest classes of animals on the planet. Squid evolved during the Jurassic period and now appear in every ocean around the world. They are ubiquitous across literature and cuisine alike, popping up in stories and on plates since at least the fourth century B.C., when Aristotle first described the beasts in “The History of Animals.”

A plant cell wall’s unique ability to expand without weakening or breaking — a quality required for plant growth — is due to the movement of its cellulose skeleton, according to new research that models the cell wall. The new model, created by Penn State researchers, reveals that chains of cellulose bundle together within the cell wall, providing strength, and slide against each other when the cell is stretched, providing extensibility.
