Materials scientist Jeffrey Catchmark displays blocks of a wound-healing biofoam developed by him and Dr. Scott Armen of Penn State College of Medicine. Image: Patrick Mansell The search for a styrofoam replacement leads to biomaterials with broader impact. Every scientific discovery has one thing in common: It started with a […]

Using metallic ink, researchers screen-print an antenna and sensor onto a stretchable sticker designed to adhere to skin and track pulse and other health indicators, and beam these readings to a receiver on a person’s clothing.

Doped charges in the CuO2 planes of cuprate superconductors form regular one-dimensional ‘stripes’ at low temperatures. Excitation with ultrafast near-infrared pulses allows direct observation of diffusive charge dynamics, which may be involved in the establishing in-plane superconductivity.
