The Precision Array for Probing the Epoch of Reionization is a radio interferometer designed to detect 21 cm Hydrogen (HI) fluctuations occuring when the first galaxies ionized intergalactic gas at around 500 million years after the Big Bang. The Penn PAPER team is led by Professor James Aguirre.
Reflective Self-Assembling Proteins
Prof. Alison Sweeney studies the biophysical properties of reflectin - a highly reflective and self-organizing squid protein found in cephalopods like the Hawaiian Bobtail squid shown here.
Nanotech Gene Sequencing
Prof. Marija Drndic is researching a technique to sequence genes by reading DNA bases as they translocate through a silicon nitride nanopore. As strands of DNA in a salt solution are driven through the pore by an applied electric field, the electric current passing through changes with the size of the base. This method could be essential for swift sequencing of genes and personalized medicine.
Functional Imaging in the Brain
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.
A synthetic peptide candidate that can be used for single molecule electronic measurements. Single molecules can act as a functioning part of a field effect transistor device as studied in Professor Charlie Johnson's lab.
Penn cosmologists, Prof. Bhuvnesh Jain and graduate student Joseph Clampitt, have, for the first time, determined the mass of dark matter along the filaments and voids of visible galaxies. The unexpected power of new, clever analysis techniques made the measurement possible much sooner than expected and shows surprising results. For an overview, see the Penn news release.
Charlie Kane, Class of 1965 Professor of Physics, is a winner of this year's Lindback Award. The Lindback Awards for Distinguished Teaching were established in 1961 and are the highest teaching award given by the University of Pennsylvania. Charlie won for being a "fantastic lecturer" who made the most challenging course "an absolute blast".
Prof. Arjun Yodh has been reappointed as Director of the Laboratory for Research on the Structure of Matter (LRSM). In his first term as Director, Arjun led the highly successful renewal of the National Science Foundation Materials Research Science and Engineering Center grant under extremely competitive conditions.
