If you have a map, you can know where you are without knowing which way you are facing. If you have a compass, you can know which way you're facing without knowing where you are. Animals from ants to mice to humans use both kinds of information to reorient themselves in familiar places, but how they determine this information from environmental cues is not well understood.
The University of Pennsylvania is participating in two National Science Foundation projects designed to advance cyberphysical systems with medical applications. Cyberphysical systems are built from and depend upon the seamless integration of computation and physical components.
Doctoral candidate Steven Jasinski of the School of Arts & Sciences is quoted for helping identify a new species of dinosaur.
Doctoral candidate Steven Jasinski of the School of Arts & Sciences is quoted about studying a new dinosaur whose keen nose made it a formidable predator.
A researcher from the University of Pennsylvania has identified a species of dinosaur closely related to Velociraptor, the group of creatures made infamous by the movie "Jurassic Park.” The newly named species likely possessed a keen sense of smell that would have made it a formidable predator.
The compound eyes found in insects and some sea creatures are marvels of evolution. There, thousands of lenses work together to provide sophisticated information without the need for a sophisticated brain. Human artifice can only begin to approximate these naturally self-assembled structures, and, even then, they require painstaking manufacturing techniques.
At the forefront of a field known as “neurocriminology,” Adrian Raine of the University of Pennsylvania has long studied the interplay between biology and environment when it comes to antisocial and criminal behavior.

Decorating the outside of cells like tiny antenna, a diverse community of sugar molecules acts like a telecommunications system, sending and receiving information, recognizing and responding to foreign molecules and neighboring cells.
Researchers from the University of Pennsylvania and Michigan State University presented new preclinical data this week that evaluates the efficacy of a gene therapy treatment for achromatopsia, a rare inherited retinal disease that involves cone cells. The disease affects humans as well as dogs.
