Crystalline materials have atoms that are neatly lined up in a repeating pattern. When they break, that failure tends to start at a defect, or a place where the pattern is disrupted. But how do defect-free materials break?

The senior design classes held in each of the School of Engineering and Applied Science’s six departments are an opportunity for University of Pennsylvania students to put their skills to the test, by picking a real-world problem and developing a new piece of technology to solve it.
University of Pennsylvania astronomers are celebrating the dedication of a new planet-hunting telescope known as Minerva-Red. Installed at the Fred Lawrence Whipple Observatory in Arizona, Minerva-Red is part of the Minerva project, an array of low-cost telescopes that are designed to discover planets orbiting stars other than the sun.
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.
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.
