Penn Researchers Discover Why E. coli Move Faster in Syrup-like Fluids Than in Water
Swimming in a pool of syrup would be difficult for most people, but for bacteria like E. coli, it’s easier than swimming in water. Scientists have known for decades that these cells move faster and farther in viscoelastic fluids, such as the saliva, mucus, and other bodily fluids they are likely to call home, but didn’t understand why.
Penn’s Engheta and Ghrist Earn National Security Science and Engineering Faculty Fellowships
When the Department of Defense offers researchers the chance to think big and take risks, and provides the funding to back it up, scientists tend to get really excited.
Four Penn Professors Among Class of 2015 AAAS Fellows
Four faculty members at the University of Pennsylvania have been named Fellows of the American Association for the Advancement of Science. They are among a class of 347 researchers that have been awarded this honor by AAAS because of their scientifically or socially distinguished efforts to advance science or its applications
Penn Chemists Put a New Twist on Chirality
Biological molecules are chiral. Like gloves, they have either left- or right-handed versions that can’t be superimposed on one another. Macromolecules like DNA are also chiral and are exclusively made of building blocks with the same handedness.
Penn Engineering team showcases ‘eye-on-a-chip’ technology
A team of graduate students from the School of Engineering and Applied Science were among seven finalists at the Collegiate Inventors Competition earlier this week.
Penn Collaborating in NSF’s Northeast Big Data Innovation Hub

Penn Team Shares in 2016 Breakthrough Prize in Fundamental Physics
The Sudbury Neutrino Observatory Collaboration, which includes physicists from the University of Pennsylvania, shared the 2016 Breakthrough Prize in Fundamental Physics.
Penn Research Contributes New Understanding of the ‘Dewetting’ Process
When a material, typically a liquid, is confined by surfaces that it doesn't like, the material can be expelled from the confining region in a process called “dewetting.”
