Even the mildest form of a traumatic brain injury, better known as a concussion, can deal permanent, irreparable damage. Now, an interdisciplinary team of researchers at the University of Pennsylvania is using mathematical modeling to better understand the mechanisms at play in this kind of injury, with an eye toward protecting the brain from its long-term consequences.
Whether it is playing a piano sonata or acing a tennis serve, the brain needs to orchestrate precise, coordinated control over the body’s many muscles. Moreover, there needs to be some kind of feedback from the senses should any of those movements go wrong.
Adult stem cells and cancer cells have many things in common, including an ability to migrate through tiny gaps in tissue. Both types of cells also experience a trade-off when it comes to this ability; having a flexible nucleus makes migration easier but is worse at protecting the nucleus’ DNA compared to a stiffer nucleus.
Three University of Pennsylvania faculty members are among this year’s Sloan Fellowship recipients. Since 1955, the Alfred P. Sloan Foundation has granted yearly fellowships to early-career scientists and scholars whose achievements and potential identify them the next generation of scientific leaders.
For centuries, geologists have recognized that the rocks that line riverbeds tend to be smaller and rounder further downstream. But these experts have not agreed on the reason these patterns exist. Abrasion causes rocks to grind down and become rounder as they are transported down the river.
Penn Dhamaka’s energetic, arm-pumping, feet-shuffling, body-twisting dance routines are inspired by traditional South Asian dance, but the all-male troupe’s flair is all their own.
When deciding what materials to use in building something, determining how those materials respond to stress and strain is often the first task. A material’s macroscopic, or bulk, properties in this area — whether it can spring back into shape, for example — is generally the product of what is happening on a microscopic scale.

For eight weeks last summer, University of Pennsylvania junior Doug Roman had the opportunity to share his sustainability philosophy at schools in Buenos Aires.
On Saturday, Feb. 1, Philly Materials Science and Engineering Day offers people of all ages the chance to participate in hands-on science and engineering activities. The event is free and open to the public.
