PHILADELPHIA –- Along an isolated stretch of the eastern shoreline of Greece, a University of Pennsylvania classics professor and his colleagues are unlocking the secrets of a partially submerged “lost” harbor town believed to have been built by the Mycenaeans 3,500 years ago.
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 -– 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.
Researchers analyzed patterns of codon usage across 74 bacteriophages using the concept of a "genome landscape," a method of visualizing long-range patterns in a genome sequence.
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.
The study’s authors believe that some women may avoid necessary tests and treatments when a doctor visit includes a step on a public scale.
