Why do some people learn a new skill right away, while others only gradually improve? Whatever else may be different about their lives, something must be happening in their brains that captures this variation.

Where water and oil meet, a two-dimensional world exists. This interface presents a potentially useful set of properties for chemists and engineers, but getting anything more complex than a soap molecule to stay there and behave predictably remains a challenge.

None of us would be alive if sperm cells didn’t know how to swim, or if the cilia in our lungs couldn’t prevent fluid buildup. But we know very little about the dynamics of so-called “living fluids,” those containing cells, microorganisms or other biological structures.
President Amy Gutmann today announced the selection of five undergraduates at the University of Pennsylvania as the inaugural President’s Engagement Prize recipients. Awarded annually to Penn students to design and undertake fully-funded local, national or global engagement projects during the first year after they graduate, the President’s Engagement Prizes underscore the high priority that Penn places on educating students to put their knowledge to work for the betterment of humankind.
The pistons in your car engine rub up against their cylinder walls thousands of times a minute; without lubrication in the form of motor oil, they and other parts of the engine would quickly wear away, causing engine failure.
Postdoctoral fellow Alexander Stewart of the School of Arts & Sciences writes about a new approach to game theory he studied with Jos
The field of metamaterials is all about making structures that have physical properties that aren’t found in nature. Predicting what kinds of structures would have those traits is one challenge; physically fabricating them is quite another, as they often require precise arrangement of constituent materials on the smallest scales.
