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

Far beneath the surface of the ocean, deep currents act as conveyer belts, channeling heat, carbon, oxygen and nutrients around the globe.
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.
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.”
Sarah Tishkoff of the Perelman School of Medicine and the School of Arts and Sciences and postdoc student Alessia Ranciaro are featured for their research that ties Africans’ lactose tolerance to the spread of cattle raising.
Janet Monge of the School of Arts and Sciences and the Penn Museum is quoted about the importance of Duffy’s Cut.
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.
