When John Crocker, a professor of chemical and biomolecular engineering in the University of Pennsylvania’s School of Engineering and Applied Science was a graduate student, his advisor gathered together everyone in his lab to “throw down the gauntlet” on a new challenge in the field.

In order for cancer to spread, malignant cells must break away from a tumor and through the tough netting of extracellular matrix, or ECM, that surrounds it. To fit through the holes in this net, those cancerous cells must elongate into a torpedo-like shape.

Critically ill infants and children do not gain extra benefit from lower blood-sugar levels, compared to higher levels within the usual care range, according to research from the Children’s Hospital of Philadelphia, the University of Pennsylvania

University of Pennsylvania researchers are now among the first to produce a single, three-atom-thick layer of a unique two-dimensional material called tungsten ditelluride. Their findings have been published in 2-D Materials.

Chemists at the University of Pennsylvania are expanding a new model that could be the first step towards better harnessing heat energy to power nanoscale devices.

On Jan. 10, about 250 Philadelphia area high school students filled a lecture hall to watch the 20th Annual Physics Demonstration Show at the University of Pennsylvania.

Nanoscale structures have properties that can’t be achieved in any other way, stemming from precise control over the structure’s composition and geometry. Unfortunately, simultaneously achieving high levels of control of both characteristics can be challenging.

Depending on the specific type, bacteria in a woman’s vagina and cervix may increase the risk of premature birth or protect against it, according to new research from the Perelman School of Medicine at the University of Pennsylvania.
