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.

Humans possess six forms of the protein actin, which perform essential functions in the body. Two in particular, β-actin and γ-actin, are nearly identical, only differing by four amino acids. Yet these near-twin proteins carry out distinct roles. A long standing question for biologists has been, how is this possible?

Gaia Tavoni, a postdoctoral fellow of the Computational Neuroscience Initiative, has been named a Swartz Foundation Fellow for Theory in Neuroscience for her research proposal suggesting pathways to investigate the brain mechanisms involved in learning and memory.

A political science professor at the University of Pennsylvania who has been studying Russian politics for more than a quarter century is in the midst of wrapping up two books.

A new collaboration between Kelly Writers House and Perry World House offers a residency program for journalists whose work puts their safety at risk.

“We know a lot about families in the United States, Sweden, a lot of high-income countries,” said University of Pennsylvania demographer Hans-Peter Kohler. “But there is a huge gap in what we know about the family in middle- and low-income countries.”

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.

Boys in all-boys’ schools do better on the general math test than boys in co-ed schools. They’re also more likely to take the science-focused math test. But test scores for girls do not improve in all-girls’ schools.

Dark matter, a mysterious form of matter that makes up about 80 percent of the mass of the universe, has evaded detection for decades. Although it doesn’t interact with light, scientists believe it’s there because of its influence on galaxies and galaxy clusters.
