PHILADELPHIA — One of the most promising innovations of nanotechnology has been the ability to perform rapid nanofabrication using nanometer-scale tips. Heating such tips can dramatically increase fabrication speeds, but high speed and high temperature have been known to blunt their atomically sharp points.
Matt Blaze of the School of Engineering and Applied Science shares his thoughts about hacking.
PHILADELPHIA — Electronic circuits are typically integrated in rigid silicon wafers, but flexibility opens up a wide range of applications. In a world where electronics are becoming more pervasive, flexibility is a highly desirable trait, but finding materials with the right mix of performance and manufacturing cost remains a challenge.
Just before sunrise on Nov. 14, the day’s first baby was born at the Hospital of the University of Pennsylvania. Around midnight, a Penn Law student closed the day studying, surrounded by books.

PHILADELPHIA — Researchers at the University of Pennsylvania are participating in a massive, interdisciplinary collaboration known as the TerraSwarm Research Center, which will study the potential applications — and risks — of “swarm-based” computing and robotics. Based at the Swarm Lab at the University of California, Berkeley, the nine-university project has received a $27.5 million, five-year grant from the Semiconductor Research Corporation and the Defense Advanced Research Projects Agency as a part of the Focus Center Research Program.
PHILADELPHIA — The disease atherosclerosis involves the build up of fatty tissue within arterial walls, creating unstable structures known as plaques. These plaques grow until they burst, rupturing the wall and causing the formation of a blood clot within the artery. These clots also grow until they block blood flow; in the case of the coronary artery, this can cause a heart attack.
