Researchers produce low-cost hand sanitizer from waste

A Tel Aviv University breakthrough allows, for the first time, a local production of ethanol—and hand sanitizer—based on plant and paper waste, using a novel lignin (a substance found in plants) degradation process. This ...

Where deep learning meets metamaterials

Breakthroughs in the field of nanophotonics—how light behaves on the nanometer scale—have paved the way for the invention of "metamaterials," man-made materials that have enormous applications, from remote nanoscale sensing ...

Smartphones may be used to better predict the weather

Flash floods occur with little warning. Earlier this year, a flash flood that struck Ellicott City, MD, demolished the main street, swept away parked cars, pummeled buildings and left one man dead.
