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.
PHILADELPHIA –- David S. Roos, the E. Otis Kendall Professor of Biology at the University of Pennsylvania, is among 78 microbiologists elected to fellowship in the American Academy of Microbiology.
Fellows of the Academy are elected annually based on their records of scientific achievement and original contributions to advance microbiology.
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.
Note for TV and radio: The University of Pennsylvania has an ISDN line on campus and a satellite uplink facility with live-shot capability near campus.
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.
PHILADELPHIA –- Researchers at the University of Pennsylvania, the University of Wisconsin-Madison and IBM Research-Zürich have fabricated an ultra sharp, diamond-like carbon tip possessing such high strength that it is 3,000 times more wear-resistant at the nanoscale than silicon.
PHILADELPHIA –- A University of Pennsylvania-led study in which training was provided to a high-stress U.S. military group preparing for deployment to Iraq has demonstrated a positive link between mindfulness training, or MT, and improvements in mood and working memory. Mindfulness is the ability to be aware and attentive of the present moment without emotional reactivity or volatility.
PHILADELPHIA –- Material scientists at the Nano/Bio Interface Center of the University of Pennsylvania have demonstrated the transduction of optical radiation to electrical current in a molecular circuit. The system, an array of nano-sized molecules of gold, respond to electromagnetic waves by creating surface plasmons that induce and project electrical current across molecules, similar to that of photovoltaic solar cells.
