New collaborative research describes how electrons move through two different configurations of bilayer graphene, the atomically-thin form of carbon. These results provide insights that researchers could use to design more powerful and secure quantum computing platforms in the future.

Inspired by observations made at the Georgia Aquarium, a new study by Penn’s Arnold Mathijssen and colleagues at the Max Planck Institute found that when a school of microscopic, self-propelled droplets known as “microswimmers” moves in the same direction inside a narrow channel, they can increase the cargo capacity—the number of particles they can carry—by tenfold.

A collaborative study that employs a combination of sophisticated algorithms and models developed by post-doctoral researcher Eugenio Piasini and professor Vijay Balasubramanian details the time scales of visual information processing across different regions of the brain. The researchers found that deeper regions of the brain encode visual information more slowly, providing a mechanism for identifying fast-moving objects and images more accurately and persistently.
