Additional challenges in bringing research online
Additional challenges in bringing research online
As research on campus slowly restarts, those whose work requires field surveys, large-scale collaborations, or travel face additional challenges in bringing their research back online.
What do ‘Bohemian Rhapsody,’ ‘Macbeth,’ and a list of Facebook friends all have in common?
To an English scholar or avid reader, the Shakespeare Canon represents some of the greatest literary works of the English language. To a network scientist, Shakespeare’s 37 plays and the 884,421 words they contain also represent a massively complex communication network.

A new study describes how external forces drive the rearrangement of individual particles in disordered solids, enabling new ways to imbue materials with unique mechanical properties.
At home, but still engaged with STEM classes
At home, but still engaged with STEM classes
While instructional laboratories on campus are closed, students, faculty, and instructors are finding creative solutions for science, math, and engineering courses and projects.
To err is human, to learn, divine
To err is human, to learn, divine
Researchers develop a new model for how the brain processes complex information: by striking a balance between accuracy and simplicity while making mistakes along the way.

Combining theoretical insights with experimental results, physicists demonstrate a new design for optoelectronic devices that could help make optical fiber communications more energy efficient.
The optimal immune repertoire for bacteria
The optimal immune repertoire for bacteria
Researchers develop a physical model that describes the optimal amount of ‘memory’ of prior infections that bacteria should have in order to efficiently mount a successful immune response.
Penn labs get creative to stay productive, connected
Penn labs get creative to stay productive, connected
In the face of a pandemic that has shuttered most physical laboratories across campus, researchers have shifted gears, maintaining work and social ties through grant- and manuscript-writing, virtual journal clubs, online coffee breaks, and more.

A squid’s eye view
Alison Sweeney of the School of Arts and Sciences discussed the complex structure of squids’ eyes, which have special lenses that allow for crisp vision in dark water. “The resolution of their eyes is approaching that of humans, their retinas are much more sensitive than ours are to light, and if you dig into the nitty-gritty of how nature figured it out, I’m forever blown away at the level of nuance to get it to work.”
