First particle tracks seen in prototype for international neutrino experiment
First particle tracks seen in prototype for international neutrino experiment
Neutrinos are the most abundant, and most mysterious, type of matter in the universe. Physicists from the School of Arts and Sciences had a hand in designing a massive instrument, the ProtoDUNE, that has detected the first evidence of these particles of matter.

The snow graphics in ‘Frozen’ can predict the mechanics of real avalanches
The Department of Computer and Information Science’s Chenfanfu Jiang recently published a study in Nature Communications that accurately models slab avalanches, bringing realistic natural phenomena to movies and practical applications for scientific predictions.
A physics treasure hidden in the pattern of wallpaper
A physics treasure hidden in the pattern of wallpaper
Charles Kane and Andrew Rappe of the School of Arts and Sciences were part of an international team that has identified a new form of insulating material that may one day provide a basis for quantum computing. The patterns found in everyday wallpaper played a role in the discovery.

Making complex 3-D surfaces with 2-D sheets
Using liquid crystal elastomer, researchers are able to transform 2-dimensional rubber-like sheets into malleable, three-dimensional shapes, with a precise amount of control for various shape sequences.

Looking to the stars
This year's Simons Observatory Collaboration conference included a community star party that consisted of a panel, a mixer with astronomers, and stargazing.
Harnessing DNA tricks to boost nanosensors
Harnessing DNA tricks to boost nanosensors
Researchers have found a way to increase the sensitivity of graphene sensors using a trick of DNA engineering. The sensors might one day be used to monitor and treat HIV.
Earthquakes at the nanoscale
Earthquakes at the nanoscale
Scientists have gotten better at predicting where earthquakes will occur, but they’re still in the dark about when they will strike and how devastating they will be. Penn researchers hope to tackle this by investigating the laws of friction at the smallest possible scale, the nanoscale.
A topological phenomenon could light the path toward faster optical communications
A topological phenomenon could light the path toward faster optical communications
A new study led by University of Pennsylvania physicist Bo Zhen investigated topological phenomena in open, or non-Hermitian, physical systems which could potentially lead to faster connection speeds in optical communications.
