A representation of blood flow changes in a rat brain during cortical spreading depression. In the experiment, a large local concentration of KCl initiates a 'wave' of neuronal depolarization that propagates outward from a central point and then repeats itself. The figure shows images of blood flow in four parallel planes located within 3 millimeters of the skull.
Professor Alison Sweeney studies bio-optical properties of cephalopods and the cellular and biochemical mechanisms of dynamic camouflage.
Euclid Mission to Explore Dark Energy
Euclid is an ESA mission to map the geometry of the dark Universe. The mission will investigate the distance-redshift relationship and the evolution of cosmic structures. Penn researchers are part of the Euclid science team.
DNA through a Solid State Nanopore
Dr. Meni Wanunu, Dr. Marija Drndic and others at the University of Pennsylvania have threaded DNA through solid state nanopores in order to gain information about chemically modified DNA. The image depicts chemically modified DNA translocating through a nanoscale pore in silicon nitride.
MRSEC Research at Penn
The P&A department plays a large role in the Laboratory for Research on the Structure of Matter (LRSM). One focus of LRSM research between faculty from different departments and schools is soft matter and how it conforms, assembles, and reconfigures in response to the geometry and chemistry of bounding surfaces and interfaces.
The World Science Festival’s annual salon series offers in-depth conversations with leading scientists, extending the discussion of the Festival’s premier public programs to graduate students, postdocs, faculty and well-informed members of the general public.

Kamien has found that many problems in soft condensed matter theory can be formulated very naturally as geometry or topology problems. “We look at problems where often the solution is about drawing a picture or building a tinker toy model of what we’re trying to understand,” explains Kamien.
