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.

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.
