High Levels of Moral Reasoning Correspond with Increased Gray Matter in Brain

Individuals with a higher level of moral reasoning skills showed increased gray matter in the areas of the brain implicated in complex social behaviordecision making, and conflict processing as compared to subjects at a lower level of moral reasoning, according to new research from the Perelman School of Medicine and the Wharton School of the University of Pennsylvania in collaboration with a researcher from Charité Universitätsmediz in Berlin, Germany.

Reverberations in Metabolism: Protein Maintains Double Duty as Key Cog in Body Clock and Metabolic Control, Penn Study Finds

Around-the-clock rhythms guide nearly all physiological processes in animals and plants. Each cell in the body contains special proteins that act on one another in interlocking feedback loops to generate near-24 hour oscillations called circadian rhythms.

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

blurb: 
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?
