PHILADELPHIA –- A team of nanotechnology researchers from the University of Pennsylvania and Columbia University has used friction force microscopy to determine the nanoscale frictional characteristics of four atomically-thin materials, discovering a universal characteristic for these very different materials. Friction across these thin sheets increases as the number of atomic layers decreases, all the way down to one layer of atoms. This friction increase was surprising as there previously was no theory to predict this behavior.
PHILADELPHIA – A team of cardiologists, materials scientists, and bioengineers have created and tested a new type of implantable device for measuring the heart’s electrical output that they say is a vast improvement over current devices. The new device represents the first use of flexible silicon technology for a medical application.
PHILADELPHIA – Psychologists led by the University of Pennsylvania have used implantable electrodes and a first-person driving game to identify the cells of the brain that indicate travel in a clockwise or counterclockwise motion, called “path cells.” The study will be published this week in the Proceedings of the National Academy of Sciences.
PHILADELPHIA –- An interdisciplinary team of physicists and geologists led by the University of Pennsylvania has made a major step toward predicting where and how large floods occur on river deltas and alluvial fans.
In a laboratory, researchers created a miniature river delta that replicates flooding patterns seen in natural rivers, resulting in a mathematical model capable of aiding in the prediction of the next catastrophic flood.
Double Agents: Penn Researchers Identify Immune Cells That Fight Parasites May Promote Allergies and Asthma
PHILADELPHIA –- Millions of people in both the developing and developed world may benefit from new immune-system research findings from the University of Pennsylvania School of Veterinary Medicine.
The Penn Vet researchers, studying how the immune system operates, have discovered a previously unidentified cell population that may be the body’s double-edged sword, fighting off parasitic infections but also causing the harmful immune responses that can lead to allergies and asthma.
PHILADELPHIA –- Ravi Desai, a bioengineering researcher completing his doctoral degree at the University of Pennsylvania, has won the 2009 JCS Prize, awarded annually to the first author of the paper judged best by the editors and editorial board of the Journal of Cell Science. Authors must be students or postdoctoral researchers to be considered for the prize.
BEIJING -- The University of Pennsylvania and Tsinghua University today announced agreements to build upon research and academic collaborations between the two schools. In particular, the universities signed agreements reaffirming their commitment to environmental sustainability, through the work of the Penn-Tsinghua T.C. Chan Center for Building Simulation and Energy Studies, founded in 2006.
University of Pennsylvania Joins International Collaboration in Government/Academics to Research "Soft Matter"
PHILADELPHIA –- The University of Pennsylvania’s Laboratory for Research on the Structure of Matter has entered into a multi-year agreement with specialty chemical producer Rhodia and the French National Center for Scientific Research to launch an international, public-private research collaboration in soft condensed matter.
