Penn Researchers Model a Key Breaking Point Involved in Traumatic Brain Injury

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.

Penn Researchers Show Nuclear Stiffness Keeps Stem Cells and Cancer Cells in Place

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.

Penn Geophysicist Teams With Mathematicians to Describe How River Rocks Round

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.
