Penn-designed Device Shows Promise for Individualized Care in Stroke Patients

blurb: 
Using a Penn-designed device to noninvasively and continuously monitor cerebral blood flow in acute stroke patients, researchers are now learning how head of bed (HOB) positioning affects blood flow reaching the brain.

Using a University of Pennsylvania-designed device to noninvasively and continuously monitor cerebral blood flow (CBF) in acute stroke patients, researchers from Penn Medicine and the Department of Physics & Astronomy in Penn Arts and Sciences are now learning how head of

Deep Ocean Current May Slow Due to Climate Change, Penn Research Finds

blurb: 
A new study by the University of Pennsylvania’s Irina Marinov and Raffaele Bernardello and colleagues from McGill University has found that recent climate change may be acting to slow down one of the ocean's "conveyer belts," with potentially serious consequences for the future of the planet’s climate.

Far beneath the surface of the ocean, deep currents act as conveyer belts, channeling heat, carbon, oxygen and nutrients around the globe.

Owl Monkeys Don’t Cheat, Penn Study Shows; Intense Fathering Plays a Role

blurb: 
A new study by University of Pennsylvania researchers shows that Azara’s owl monkeys (Aotus azarae) are unusually faithful, an unusual trait among mammals.

True monogamy is rare in the animal kingdom. Even in species that appear to “mate for life,” genetic maternity and paternity tests have revealed that philandering often takes place.

Audio: Does Teaching Kids to Get ‘Gritty’ Help Them Get Ahead?

Angela Duckworth of the School of Arts and Sciences says, “This quality of being able to sustain your passions, and also work really hard at them, over really disappointingly long periods of time, that’s grit.”

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.

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.
