An interdisciplinary team of University of Pennsylvania researchers has now applied a cutting-edge technique for rapid gene sequencing toward measuring other nanoscopic structures. By passing nanoscale spheres and rods through a tiny hole in a membrane, the team was able to measure the electrical properties of those structures’ surfaces.
Two solids made of the same elements but with different geometric arrangements of the atoms, or crystal phases, can produce materials with different properties. Coal and diamond offer a spectacular example of this effect.
One of the goals of genome sequencing is to identify genetic mutations associated with increased susceptibility to disease. Yet by and large these discoveries have been made in people of European or Asian ancestry, resulting in an incomplete picture of global genetic variation in disease vulnerability.
University of Pennsylvania researchers have made another advance in understanding how the brain detects errors caused by unexpected sensory events. This type of error detection is what allows the brain to learn from its mistakes, which is critical for improving fine motor control.
An interdisciplinary team of engineers from the University of Pennsylvania has made a discovery regarding the surface properties of graphene, the Nobel-prize winning material that consists of an atomically thin sheet of carbon atoms.

Alison Sweeney of the School of Arts & Sciences is interviewed about studying the sex lives of corals.
For decades, researchers have used petri dishes to study cell movement. These classic tissue culture tools, however, only permit two-dimensional movement, very different from the three-dimensional movements that cells make in a human body.
Dinosaurs are often depicted as giant, frightening beasts. But every creature is a baby once.
A new examination of a rock slab containing fossils of 24 very young dinosaurs and one older individual is suggestive of a group of hatchlings overseen by a caretaker, according to a new study by University of Pennsylvania researchers.
