Penn Research Helps Identify New Brain Cell Involved in Navigation
August 5, 2013
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 loca
Penn: Variants at Gene Linked to Kidney Disease, Sleeping Sickness Resistance
July 29, 2013
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.
Penn Research Helps Make Advance in 'Programmable Matter' Using Nanocrystals
July 26, 2013
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?
Penn Engineer Mark Harding Learns About Himself Via Teaching
July 23, 2013
(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.)
Penn Researchers Help Show New Way to Study and Improve Catalytic Reactions
July 18, 2013
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.
Nano-Noses at Penn Science Cafe
July 17, 2013
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.
John Swartley Appointed Associate Vice Provost for Research at Penn
July 16, 2013
John S. Swartley has been named associate vice provost for research and executive director of the Center for Technology Transfer at the University of Pennsylvania. 
President Obama Requests Bioethics Commission to Play Early Role in BRAIN Initiative
July 11, 2013
WASHINGTON -- As part of the new Brain Research through Advancing Innovative Neurotechnologies, or BRAIN Initiative, announced in April, President Barack Obama has asked the Presidential Commission f
Two Penn Researchers Named Simons Investigators
July 10, 2013
Rajeev Alur and Randall Kamien of the University of Pennsylvania have been awarded five-year, $500,000 grants from the Simons Foundation, as part of its 2013 class of Simons Investigators.
Penn Biologists Simulate a Cell in Action
June 28, 2013
The inner workings of a cell involve hundreds of thousands of discrete molecules, engaged in a repeating cycle of interactions that sustain life.
