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.”
Penn Research Shows Mountains Are Only Minor Contributors to Sediment Erosion and Climate Regulation
PHILADELPHIA — Though churning smokestacks, cud-chewing cows and gasoline-burning vehicles are contributing constantly to greenhouse gas emissions, there are also many processes that do the reverse, pulling molecules like carbon dioxide out of the atmosphere. One of these is chemical weathering, which occurs when rock turns into soil. Carbon dioxide molecules and rain combine to dissolve rock, and the weathering products, including sediment, eventually make their way through waterways to the ocean where some become trapped on the ocean bottom and in coral reefs and seashells.
David Kennedy of the Perelman School of Medicine discusses how he uses a new app, called MD Connect Me, to give families updates via text or email throughout the procedure.
PHILADELPHIA — Directed assembly is a growing field of research in nanotechnology in which scientists and engineers aim to manufacture structures on the smallest scales without having to individually manipulate each component. Rather, they set out precisely defined starting conditions and let the physics and chemistry that govern those components do the rest.
