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

blurb: 
An interdisciplinary team of researchers is using mathematical modeling to better understand the mechanisms at play in traumatic brain injury, with an eye toward protecting against its long-term consequences.

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’s Morris Arboretum Is a Year-round Oasis

It may be that many people don’t think of the Morris Arboretum when it is cold and snowy outside, but the University of Pennsylvania site offers unique scenic views and seasonal activities aplenty even in the winter.

Muscle-controlling Neurons Know When They Mess Up, According to Penn Research

blurb: 
A team of researchers from Penn and Princeton has begun to unravel the decades-spanning paradox concerning how the brain's motor-control feedback system works.

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.

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

blurb: 
Researchers at the University of Pennsylvania have shown that cell migration through micron-size pores is regulated by lamin-A, a nuclear protein that is very similar to the fibrous ones that make up hair.

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 Penn Researchers Awarded Sloan Fellowships

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.

Penn Geophysicist Teams With Mathematicians to Describe How River Rocks Round

blurb: 
A new study by the University of Pennsylvania’s Douglas Jerolmack, working with mathematicians at Budapest University of Technology and Economics, has found that rocks traveling down a riverbed follow a distinct pattern, first becoming rounder, and then smaller.

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 Performers Celebrate Culture Through South Asian Dancing With a Twist

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.

Penn Researchers ‘Design for Failure’ With Model Material

blurb: 
Researchers at the University of Pennsylvania have devised a method to study stress at the macro and micro scales at the same time, using a model system in which microscopic particles stand in for molecules.

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.
