A political science major and student fellow at Penn's Perry World House is working with a team of student fellows to construct a website showing how cities deal with an influx of climate change refugees.

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.

In mammals, including humans, the cells that contract the heart muscle and enable it to beat do not regenerate after injury. After a heart attack, there is a dramatic loss of these heart muscle cells and those that survive cannot effectively replicate.

Dropping a smartphone on its glass screen, which is made of atoms jammed together with no discernible order, could result in it shattering. Unlike metals and other crystalline materials, glass and many other disordered solids cannot be deformed significantly before failing and, because of their lack of crystalline order, it is difficult to predict which atoms would change during failure.

With streaming movies and UltraHD television taking more and more bandwidth, there is a race to deliver data into people’s homes as quickly as possible. Light-based fiber optic connections promise far faster data rates than standard electricity-based coaxial cables, so making laser sources smaller, cheaper and more stable is a high priority for engineers.

These posts, many of which are submitted late at night or in the early morning hours, often reveal mental, physical, and emotional exhaustion.

The minor, spearheaded by the Price Lab for Digital Humanities, includes courses from a broad range of departments, from Anthropology to Religious Studies.

What can Twitter reveal about people with attention-deficit/hyperactivity disorder, or ADHD?

Alison Sweeney of the University of Pennsylvania has been studying giant clams since she was a postdoctoral fellow at the University of California, Santa Barbara.

Filtration membranes are, at their core, sponge-like materials that have micro- or nanoscopically small pores. Unwanted chemicals, bacteria and even viruses are physically blocked by the maze of mesh, but liquids like water can make it through.
