Penn Researchers Home in on What's Wearing Out T Cells

Sometimes even cells get tired. When the T cells of your immune system are forced to deal over time with cancer or a chronic infection such as HIV or hepatitis C, they can develop "T cell exhaustion," becoming less effective and losing their ability to attack and destroy the invaders of the body.

Penn Historian Discusses the Threat Birds Posed to the Power Grid in 1920s California

In a new paper in the journal Environmental Humanities, the University of Pennsylvania’s Etienne Benson examines the suspected cause of the problems to the power grid in Southern California in the 1920s: voluminous streams of bird excrement.

In 1913 in Southern California, two 241-mile-long electric lines began carrying power from hydroelectric dams in the Sierra Nevada to customers in Los Angeles—a massive feat of infrastructure. In 1923, power company Southern California Edison upgraded the line to carry 220,000 volts, among the highest voltage lines in the world at the time.

Penn Engineers Show How “Perfect” Materials Begin to Fail

Crystalline materials have atoms that are neatly lined up in a repeating pattern. When they break, that failure tends to start at a defect, or a place where the pattern is disrupted. But how do defect-free materials break?

Penn Vet Lends Expertise to Improve Colombian Cattle Producers’ Livelihoods

Emphasizing a holistic management approach based on sound nutrition and assisted reproduction strategies, the University of Pennsylvania’s Victor Absalón-Medina's aim is to promote cross-institutional collaborations to help Colombian farmers keep their animals healthy, productive and profitable.

Cattle in the United States are generally managed to either produce milk or to produce beef. However, in most of the world, cattle are counted on to do both in what are called dual-purpose production systems.

Penn Medicine Study Reveals Novel Use of 3-D Imaging Technique for Precise Measurement of Injectable Wrinkle Reducers

A three-dimensional imaging technique often used in the automotive and aerospace industries for accurate measurement may be useful to measure the efficacy of injectable wrinkle reducers such as Botox and Dysport, according to new research from the Perelman School of Medicine at the University of Pennsylvania

Penn Medicine: Wide Variability in Organ Donation Rates: Midwest Leads Nation in Highest Rates of Donations

More than 123,000 Americans are currently waiting for lifesaving organ transplants, but 21 patients die each day because there aren't enough organs to go around. New research shows wide variation in the number of eligible organ donors whose loved ones consent to organ donation across the country.

Dean of Penn’s Perelman School of Medicine: Precision Medicine is “Personalized, Problematic, and Promising”

The rapidly emerging field of precision medicine is a “disruptive innovation” that offers the possibility of remarkably fine-tuned remedies to improve patient health while minimizing the risk of harmful side effects, says J. Larry Jameson, MD, PhD, dean of the Perelman School of Medicine and executive vice president of the University of Pennsylvania for the Health System, in this week’s issue of the New England Journal of Medicine.

Penn Study Links Better "Good Cholesterol" Function With Lower Risk of Later Heart Disease

HDL is the “good cholesterol” that helps remove fat from artery walls, reversing the process that leads to heart disease. Yet recent drug trials and genetic studies suggest that simply pushing HDL levels higher doesn’t necessarily reduce the risk of heart disease. Now, a team led by scientists from the Perelman School of Medicine at the University of Pennsylvania has shown in a large, forward-looking epidemiological study that a person’s HDL function—the efficiency of HDL molecules at removing cholesterol—may be a better measure of coronary heart disease risk and a better target for heart-protecting drugs.
