New research from Penn Medicine overturns what was previously known about a compound associated with reductions in obesity and diabetes risk.
Graduating senior and photographer Isabel Zapata captured 57 of her classmates in places of significance to create Torch Magazine. The publication features their reflections as well as her portraits.
In healthy people, a tightly controlled process balances the activity of osteoblasts, which build bone, and osteoclasts, which break it down. Damage to cells’ mitochondria can make that process go awry, meaning exposure to cigarette smoke, alcohol, environmental toxins can increase the risk of osteoporosis.
With a mussel hatchery in the future for the Schuylkill River, students in Byron Sherwood’s field biology course used scientific rigor to ask how effectively these filter feeders might render the water clean.
Understanding the microbiome, the collection of bacteria, viruses, and fungi in the gut, is helping to sort out the intricacies of diet, chronobiology, cancer treatment, and more.
Kellie Ann Jurado has been recognized by President Amy Gutmann for her research on the immune system and viral infections. Her current work is on the immune response during a Zika infection.
A new study finds that whether a wound like a diabetic foot ulcer heals or progresses to a worse outcome, including infection or even amputation, may depend on the microbiome within that wound.
Penn researchers will be involved in a weeklong series of interactive activities and events across the city as part of the Philadelphia Science Festival.
Superstitious beliefs may seem irrational, but they catch on in a society. Using an evolutionary approach to studying the emergence of coordinated behaviors, Erol Akçay and Bryce Morsky showed how a jumble of individual beliefs, including superstitions, coalesce into an accepted social norm.
Taking a game theory approach to study cooperation, School of Arts and Sciences evolutionary biologists find that empathy can help cooperative behavior ‘win out’ over selfishness.
