George Hajishengallis of the School of Dental Medicine and an international team of colleagues have found that “training” the immune system causes changes in the precursors of immune cells in the bone marrow. These changes could facilitate a more robust response to future infections or even enable the immune system to regenerate faster after chemotherapy.

When a cancer patient receives a bone marrow transplant, time is of the essence. Healthy stem cells, which can restart the production of blood cells and immune system components after a patient’s own are compromised, need to make their way from the circulatory system into the bones as quickly as possible.

Children who eat fish at least once a week sleep better and have IQ scores that are 4 points higher, on average, according to new findings from the University of Pennsylvania published in Scientific Reports.

Gene therapy holds promise for treating a variety of diseases, including some inherited blinding conditions. But for a gene therapy to be effective, one must know the precise gene responsible for a given individual’s disorder and develop a tailored treatment.

Specifically, 40 percent of sexual-minority adolescents seriously considered suicide compared to 15 percent of their heterosexual counterparts, and nearly a quarter attempted suicide compared to approximately 6 percent of those in the sexual majority.

In a historic move, the U.S. Food and Drug Administration (FDA) today approved a gene therapy initially developed by researchers at the University of Pennsylvania and Children’s Hospital of Philadelphia (CHOP) for the treatment of a rare, inherited form of retinal blindness.

Nine American research universities and a major cancer institute today announced plans to give would-be life scientists clear, standardized data on graduate school admissions, education and training opportunities and career prospects.

One way to learn about climate change is to read about it, exploring the scientific literature, perusing science news and combing through reams of relevant data. Another way is to experience it firsthand.

For many people with advanced Type 2 diabetes, taking insulin is a regular part of their routine, helping them control their blood sugar by signaling the metabolism of glucose. But recently, researchers have been investigating GLP-1, a peptide that gets activated when people eat, triggering insulin through a more natural pathway.

Imagine you’re in a restaurant, hungry, anxious and a bit irritable awaiting your food order to arrive at the table. The server exits the kitchen with a tray full of steaming plates and a flood of relief washes over you.
