No one can travel inside the earth to study what happens there. So scientists must do their best to replicate real-world conditions inside the lab.

The immune system is constantly performing surveillance to detect foreign organisms that might do harm. But pathogens, for their part, have evolved a number of strategies to evade this detection, such as secreting proteins that hinder a host’s ability to mount an immune response.

Researchers from the University of Pennsylvania and other international universities are working to save an invaluable scientific resource badly damaged during Hurricane Maria: a population of rhesus macaques living on a remote island, as well as the staff and facilities that support them.

The A. James Clark Scholars Program has been established in the School of Engineering and Applied Science at the University of Pennsylvania with an extraordinary $15 million gift from the A. James & Alice B. Clark Foundation. It is the largest one-time gift to undergraduate support in the University’s history.

by Erica AndersenWhen University of Pennsylvania undergraduate Kyle Kersey wants to describe his research, he finds it difficult to delve into the intricacies of coordination, solubility and steric effects. So he’s settled on a different tactic.“The word I like to use is ‘humbling,’” says Kersey.

The University of Pennsylvania’s Laboratory for Research on the Structure of Matter has been awarded a six-year, $22.6 million center grant from the National Science Foundation to support LRSM’s work in cutting-edge materials.

What if with the click of a button, a clinician could improve and personalize a patient’s treatment for a mental illness like post-traumatic stress disorder, depression or panic disorder?

Glass is everywhere. Whether someone is gazing out a window or scrolling through a smartphone, odds are that there is a layer of glass between them and whatever it is they’re looking at.

In 1974, images acquired from NOAA satellites revealed a puzzling phenomenon: a 250,000 square kilometer opening in the winter sea ice in the Weddell Sea, south of South America. The opening, known as a polynya, persisted over three winters. Such expansive ice-free areas in the ocean surrounding Antarctica have not been seen since, though a small polynya was seen last year.
