Prof. Charlie Johnson's lab has produced new experiments demonstrating that carbon nanotube transistors (CNT) can detect minute quantities of biomarkers of diseases in less time than conventional methods. Antibodies attached to CNT on a silicon chip change the electrical properties of the chip upon antibody-antigen binding hence detecting disease biomarkers.
Supernovae from the Sloan Digital Sky Survey

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.
The image depicts a nanobiosensor consisting of a carbon nanotube (gray) covalently attached to the coxsackie-adenovirus receptor (magenta). This device detects the adenovirus, one of the viruses responsible for the common cold, when Knob proteins from the virus capsid (orange) bind to the receptor (magenta). These devices were synthesized in Prof. Charlie Johnson's group.
Dipole magnets at the Large Hadron Collider
Protons at the LHC are accelerated to 7 TeV (the equivalent energy to an electron subjected to the potential of more than 4.5 trillion batteries laid end-to-end). To circulate such powerful beams of particles, the LHC employs superconducting dipole magnets like those shown to provide a magnetic field almost 100,000 times stronger than the earth's magnetic field.
common set of intricate cell surface patterns are observed in many different
kinds of organisms, from insects to plant pollen to fungal spores to eyelash
mite carapaces. These patterns are most famous in the popular imagination
when they’re found on pollen, and can be reticulate, hexagonal, striped, spiky,
knobbed, lobed, etc. To boot, the patterns definitely aren’t random - one
tree species will produce billions of nearly identical pollen cells within a
single tree and do so stably for millions of years - pollen is a great way to
identify things in the fossil record.
The Simons Foundation has just announced the
establishment of the Simons Collaboration on Cracking the Glass Problem,
bringing together an international team of scientists, including Professor
Andrea Liu, under the direction of Professor Sidney Nagel of the University of
Keisuke Yoshihara, a postdoctoral fellow in experimental
particle physics in the Department of Physics and Astronomy at the University
of Pennsylvania, received a "Young Scientist Award" at the 71st
Annual Meeting of the Physical Society of Japan, which took place 19-22 March
Dr. Yoshihara earned this recognition as a result of his
work as a graduate student at the University of Tokyo on the discovery and
subsequent study of the Higgs boson in the ATLAS Experiment at the CERN Large
