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.

PHILADELPHIA -- University of Pennsylvania Trustee Robert M. Levy and Diane v.S. Levy have made a $5 million gift designated for faculty support. The gift will be used to endow a Penn Integrates Knowledge Professorship, which will be named the Diane v.S. and Robert M. Levy University Professorship.
The announcement was made by Penn President Amy Gutmann.
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.
PHILADELPHIA –- Researchers at the University of Pennsylvania have developed a new, carbon-based nanoscale platform to electrically detect single DNA molecules.
Using electric fields, the tiny DNA strands are pushed through nanoscale-sized, atomically thin pores in a graphene nanopore platform that ultimately may be important for fast electronic sequencing of the four chemical bases of DNA based on their unique electrical signature.
