MicroRNA and Nanopores

Dr. Meni Wanunu, Prof. Marija Drndic and others at Penn have used solid state nanopores to study microRNA. Target microRNA strands (blue) from living tissue are hybridized with a probe RNA sequence (red). These RNA duplexes are then collected by magnetic beads (orange) that are coated with a p19 protein (green).  The RNA duplexes are then removed from the proteins and delivered to the nanopore.


Topological Insulators

Recent physics research shows how spin-orbit coupling can rearrange electronic bands in a solid to make a "topological insulator" - a new quantum phase of matter with conductive surfaces even though its bulk is insulating.  Penn physicists Professor Charlie Kane and Professor Gene Mele pioneered the theoretical discovery of such materials in 2005.


Jamming and the Glass Transition

Professor Andrea Liu's group studies the theory of jamming - the phenomenon wherein a system that normally flows much like a liquid (as with foams) become solid-like when subjected to shear stress.

Outreach Effort for Penn Physics and Astronomy

At the Penn Summer Science Academy (PSSA) students listen to a lecture, delivered from CERN by Professor Elliot Lipeles, on the discovery of a Higgs-like particle the day after the international announcement.
