PHILADELPHIA — How does one’s experience of an event get translated into a memory that can be accessed months, even years later? A team led by University of Pennsylvania scientists has come closer to answering that question, identifying key molecules that help convert short-term memories into long-term ones. These proteins may offer a target for drugs that can enhance memory, alleviating some of the cognitive symptoms that characterize conditions including schizophrenia, depression and Parkinson’s and Alzheimer’s diseases.
PHILADELPHIA — Computers may be getting faster every year, but those advances in computer speed could be dwarfed if their 1’s and 0’s were represented by bursts of light, instead of electricity.
Researchers at the University of Pennsylvania have made an important advance in this frontier of photonics, fashioning the first all-optical photonic switch out of cadmium sulfide nanowires. Moreover, they combined these photonic switches into a logic gate, a fundamental component of computer chips that process information.
Karen Okigbo really is a mover and a shaker. And the University of Pennsylvania is the right spot for her.
Born in Nigeria, Okigbo lived in Kenya for a few years before she flew halfway around the world and relocated to Fargo, N.D., with her family.
When she found herself at the top of her class in high school, she decided to hit the East Coast and moved up to the Ivy League, where she earned a B.A. in political science at Princeton University.
David Abrams and R. Polk Wagner of the Law School are cited for their research about patent law.
PHILADELPHIA — Ancient pollen and charcoal preserved in deeply buried sediments in Egypt’s Nile Delta document the region’s ancient droughts and fires, including a huge drought 4,200 years ago associated with the demise of Egypt’s Old Kingdom, the era known as the pyramid-building time.
