PHILADELPHIA –- For the third consecutive time, the Brookings Institution has been ranked Think Tank of the Year in the University of Pennsylvania Global Go-To Think Tank Report. The Report, begun in 2006, ranks more than 6,500 institutions worldwide that help bridge the gap between knowledge and public policy.
PHILADELPHIA — Breaking up is hard to do — and can be detrimental to one’s reproductive fitness, according to a new University of Pennsylvania study.
Focusing on wide-eyed, nocturnal owl monkeys, considered a socially monogamous species, the research reveals that, when an owl monkey pair is severed by an intruding individual, the mate who takes up with a new partner produces fewer offspring than a monkey who sticks with its tried-and-true partner.
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.
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.”
