How quickly can a bubble pop?

Assistant professor of physics and astronomy Saurabh Nath designed an “air-loving” membrane that can pop underwater bubbles in milliseconds, while discovering a fundamental law that governs these ephemeral spheres.

What happens when an iceberg melts?

With ice balls, lasers, and cameras, School of Arts & Sciences’ Hugo Ulloa recreated a melting iceberg in his lab. This project revealed that icebergs don’t sit passively on the water’s surface but actually release dense, cold water and jet across the surface, churning and mixing everything in their paths.

Penn Medicine, CHOP team awarded Breakthrough Prize for developing gene therapy for inherited blindness
Jean Bennett and Albert Maguire

Physician-scientists Jean Bennett and Al Maguire (right and left, respectively, pictured in their home), and Katherine High received the 2026 Breakthrough Prize in Life Sciences for their trailblazing work on the first FDA-approved gene therapy for an inherited condition, which dramatically improves sight in people with a form of blindness called Leber congenital amaurosis.

Gravity follows Newton and Einstein’s rules, even at cosmic scales
An artist's depiction of two galaxies, side-by-side, swriling at different velocites.

The cosmic microwave background, the faint afterglow of the Big Bang that fills all of space, passes through massive galaxy clusters whose motion slightly alters the light, allowing scientists to measure how fast the clusters are moving toward one another and test how strongly gravity pulls across the largest distances in the universe.

Gravity follows Newton and Einstein’s rules, even at cosmic scales

By tracking galaxy clusters hundreds of millions of lightyears apart, Penn physicist Patricio Gallardo and collaborators find that the laws of gravity written by Newton and Einstein still hold, leaving little doubt that invisible dark matter exists.
