PHILADELPHIA –- The Positive Psychology Center of the University of Pennsylvania and the John Templeton Foundation have announced the recipients of the 2010 Templeton Positive Neuroscience Awards, $2.9 million given to 15 new research projects at the intersection of neuroscience and positive psychology.
The winning projects explore a range of topics including how the brain enables humans to flourish, the biological bases of altruism and the effects of positive interventions on the brain.
PHILADELPHIA — Marsha I. Lester and Gary Molander of the University of Pennsylvania have been named 2010 fellows of The American Chemical Society, an honor bestowed on 192 scientists who have demonstrated outstanding accomplishments in chemistry and made important contributions to ACS, the world’s largest scientific society.
Lawrence Holzman of the School of Medicine discusses a study on kidney disease among African-Americans.
Jeffrey Weiser of the School of Medicine says there is such a thing as good bacteria.
PHILADELPHIA –- Bioengineers at the University of Pennsylvania have created a system to control the flexibility of the substrate surfaces on which cells are grown without changing the surface properties, providing a technique for more controlled lab experiments on cellular mechanobiology, an important step in the scientific effort to understand how cells sense and respond to mechanical forces in their environment.
University of Pennsylvania School of Medicine researchers have described a previously unknown biological mechanism in cells that prevents them from cannibalizing themselves for fuel. The mechanism involves the fuel used by cells under normal conditions and relies on an ongoing transfer of calcium between two cell components via an ion channel. Without this transfer, cells start consuming themselves as a way of to get enough energy.
PHILADELPHIA -– The mechanism by which a herpes virus invades cells has remained a mystery to scientists, but now research from Tufts University and the University of Pennsylvania reveals the unusual structure of a key member of the protein complex that allows a herpes virus to invade cells.
The new map details an essential piece of the herpes virus “cell-entry machinery,” providing scientists with a new target for antiviral drugs.
