PHILADELPHIA –- The University of Pennsylvania School of Engineering and Applied Science has received a five-year, $7.5 million grant to draw inspiration from biological organisms, including humans, in order to create principles of cooperation to control teams of next-generation, unmanned, robotic vehicles.

PHILADELPHIA -– The preservation of ancient Maya sites, efforts to sustain modern Maya cultural traditions and the need to conserve vanishing tropical forests and coastal environments are all are on the agenda April 11-13 when the University of Pennsylvania Museum of Archaeology and Anthropology colla

PHILADELPHIA –- The 200th anniversary in February 2009 of the birth of Charles Darwin, originator of the modern theory of evolution, is just months away.

PHILADELPHIA -– A team of scientists led by University of Pennsylvania veterinary researchers have identified a gene, TEX11, located on the X chromosome, which when disrupted in mice renders the males sterile and reduces female fecundity. This is the first study of the genetic causes of infertility that links a particular sex chromosome meiosis-specific gene to sterility.

PHILADELPHIA – University of Pennsylvania scientists studying macrophages, the biological cells that spring from white blood cells to eat and destroy foreign or dying cells, have discovered how these “policemen” differentiate between friend and foe. The paper appears as the cover article in the March 10 edition of the Journal of Cell Biology.

PHILADELPHIA -- Biologists at the University of Pennsylvania and Harvard University have examined the complete genomes of viruses that infect the bacteria E. coli, P. aeruginosa and L. lactis and have found that many of these viral genomes exhibit codon bias, the tendency to preferentially encode a protein with a particular spelling.

PHILADELPHIA -– Scientists at the University of Pennsylvania School of Veterinary Medicine have identified a protein, ISG15, that inhibits the Ebola virus from budding, the process by which viruses escape from cells and spread to infect neighboring cells.

PHILADELPHIA –- For centuries, engineers have bent and torn metals to test their strength and ductility. Now, materials scientists at the University of Pennsylvania School of Engineering and Applied Science are studying the same metals but at nanoscale sizes in the form of wires a thousand times thinner than a human hair.

PHILADELPHIA -- Today, researchers at the University of Pennsylvania and their U.S. ATLAS collaborators joined colleagues around the world to celebrate a pivotal landmark in the construction of the Large Hadron Collider (LHC) – the lowering of the final piece of the ATLAS particle detector into the underground collision hall at CERN in Geneva, Switzerland.

PHILADELPHIA -– A new study from the University of Pennsylvania points to increased health risks for women owing to their higher level of discomfort about being weighed in public. The study showed that college-age females, more than their male counterparts, experience high degrees of discomfort at the prospect of being weighed in the presence of others.
