Guobin Yang has an unquenchable interest in the effect of digital media on society and social movements. China, Yang’s homeland, has been quick to pull the censorship trigger on media of all sorts that report events the government construes
PHILADELPHIA — Last year, a team of University of Pennsylvania physicists showed how to undo the “coffee-ring effect,” a commonplace occurrence when drops of liquid with suspended particles dry, leaving a ring-shaped stain at the drop’s edges. Now the team is exploring how those particles stack up as they reach the drop’s edge, and they discovered that different particles make smoother or rougher deposition profiles at the drop edge depending on their shape.
While some Ivy League professors are clean-cut academics who wear suits with bowties and carry stacks of books from the library, others shatter that image.
Instead, some wear jeans and explore very dark, far-away places. One of those researchers studies the underworld of the sex trade -- not just in Philadelphia but also in New York City and in India.

In 1950, the University of Pennsylvania Museum of Archaeology and Anthropology sent scholars to a site in central Turkey, about 50 miles southwest of Ankara. There they began an effort to uncover — literally and figuratively — details about the societies and cultures of the people who lived there hundreds to thousands of years before.
PHILADELPHIA — By showing that tiny particles injected into a liquid crystal medium behave as predicted by existing mathematical theorems, physicists have opened the door for the creation of a host of new materials with properties that do not exist in nature.
The findings show that researchers can create a "recipe book" to build new materials of sorts using topology, a major mathematical field that describes the properties that do not change when an object is stretched, bent or otherwise “continuously deformed.”
