A Clearer View of Bats in the Wild

OPTICS & PHOTONICS Researchers combine thermal, ultrasonic, and near-infrared sensing in a non-invasive method for studying the flying mammals—enabling more informed conservation science.

Soft “Steam Engines” Powered by Light

OPTICS & PHOTONICS Researchers envision that miniature paddling robots, energized and controlled either by natural or artificial light, might someday be used to sop up oil or chemicals in polluted waters.

Supercharging Optical-Disk Capacity

OPTICS & PHOTONICS Team’s work increases the potential practicality of spectral-hole burning, a data storage technique that might someday enable plastic disks holding hundreds of terabytes each.
