Both basic scientists and clinicians have an interest in how the cells of our body move. Cells must be mobile in order for organisms to grow, to heal, to transmit information internally, to mount immune responses and to conduct a host of other activities necessary for survival.

A new analysis of dinosaur fossils by University of Pennsylvania researchers has revealed that a number of specimens of the genus Psittacosaurus — once believed to represent three different species — are all members of a single species.

Last week, 56 middle school-age girls flocked to Penn to take their computer savvy to the next level by learning to program. It wasn’t long ago that their instructor, Kate Miller, was in their shoes.

Using direct human brain recordings, a research team from the University of Pennsylvania, Drexel University, the University of California, Los Angeles, and Thomas Jefferson University has identified a new type of cell in the brain that helps people to keep track of their relative loc

A new study led by University of Pennsylvania researchers involves a classic case of evolution’s fickle nature: a genetic mutation that protects against a potentially fatal infectious disease also appears to increase the risk of developing a chronic, debilitating condition.

When University of Pennsylvania nanoscientists created beautiful, tiled patterns with flat nanocrystals, they were left with a mystery: why did some sets of crystals arrange themselves in an alternating, herringbone style, even though it wasn’t the simplest pattern?

(This is the second in a series about University of Pennsylvania students who took their arguments in support of federal student financial aid to Washington this summer in a project organized by the Office of Student Registration and Financial Services. Other profiles feature students Kristin Thomas and Mounica Gummadi.)

Catalysts are everywhere. They make chemical reactions that normally occur at extremely high temperatures and pressures possible within factories, cars and the comparatively balmy conditions within the human body. Developing better catalysts, however, is mainly a hit-or-miss process.

Physicist Charlie Johnson connects the biological to the digital, using graphene and carbon nanotubes to turn chemical interactions into electrical signals. Johnson will explain how attaching biological structures, such as antibodies, to these flat or rolled-up lattices of carbon atoms has enabled him and his colleagues to build new kinds of sensors, detecting things like Lyme disease bacteria.
