A team of University of Pennsylvania engineers has used a pattern of nanoantennas to develop a new way of turning infrared light into mechanical action, opening the door to more sensitive infrared cameras and more compact chemical-analysis techniques.

The allure of personalized medicine has made new, more efficient ways of sequencing genes a top research priority. One promising technique involves reading DNA bases using changes in electrical current as they are threaded through a nanoscopic hole.
Jordan Miller of the School of Engineering and Applied Science explains how a 3D-printing technique developed in the lab of Penn Engineering professor Chris Chen could help grow organs for transplantation.
Anyone who has flown in an airplane knows about turbulence, or when the flow of a fluid — in this case, the flow of air over the wings — becomes chaotic and unstable. For more than a century, the field of fluid mechanics has posited that turbulence scales with inertia, and so massive things, like planes, have an easier time causing it.
