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?

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.

Olivia Lenz graduated from the University of Pennsylvania in May, but she is sticking around to continue something she started as a sophomore: seeking answers to the subtle cycle of sleep. 

Michael Katz has been elected to the American Philosophical Society.  He is the Walter H. Annenberg professor of history and a research associate at the Population Studies Center at the University of Pennsylvania.
