Collaboration Solves Structure of Herpes Virus Protein, Provides New Drug Directions

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.

First Step Towards Electronic DNA Sequencing: Translocation Through Graphene Nanopores

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.

Penn Researchers Discover New Role for Master Regulator in Cell Metabolism, Response to Stress

AMP-activated protein kinase, or AMPK, is a master regulator protein of metabolism that is conserved from yeast to humans. When a cell is low on fuel, AMPK shuts down processes that use energy and turns on processes that produce energy.

Biologists have been studying how AMPK works for several decades and know that once it is activated, AMPK turns on a large number of genes by passing the "make more energy" message through numerous signaling cascades in the cell. What was not known, until now, was that AMPK also works via an epigenetic mechanism to slow down or stop cell growth.

East Coast Exclusive from China: "Secrets of the Silk Road"

With graceful eyelashes, long flaxen hair and serene expression, the "Beauty of Xiaohe" seems to have just softly fallen to sleep-yet she last closed her eyes nearly 4,000 years ago.  She was found, and excavated, in 2003, one of hundreds of spectacularly preserved mummies buried in the harsh desert sands of the vast Tarim Basin, in the Far Western Xinjiang Uyghur Autonomous Region of China.
