Postdoctoral researcher Laura Fox of the School of Engineering and Applied Science shares information about studying the effects of climatic warning on steppe vegetation in Mongolia.
Mitch Marcus of the School of Engineering and Applied Science discusses the influence of ENIAC, the world’s first electronic computer, on today’s modern devices.
PHILADELPHIA — Even in trace quantities, the radioactive gas radon is very dangerous; it is second only to cigarette smoking as a cause of lung cancer deaths in the United States.
In July, the U.S. scored a major international soccer victory. While the nation was unable to bring home the Women’s World Cup, Team DARwIn took first place in the Humanoid Kid Size competition at the 2011 RoboCup tournament in Istanbul, Turkey. The robots, whose name stands for “Dynamic Anthropomorphic Robot with Intelligence,” are a collaboration between the University of Pennsylvania and Virginia Tech.
PHILADELPHIA — Renaissance architects demonstrated their understanding of geometry and physics when they built whispering galleries into their cathedrals. These circular chambers were designed to amplify and direct sound waves so that, when standing in the right spot, a whisper could be heard from across the room. Now, scientists at the University of Pennsylvania have applied the same principle on the nanoscale to drastically reduce emission lifetime, a key property of semiconductors, which can lead to the development of new ultrafast photonic devices.
