Smart materials that block signals: the next big thing in tech?

May 3, 2026

Electronics keep shrinking but they still need protection from unwanted radio waves. Old-school metal shields work fine, but they’re heavy and can’t adapt. A new approach uses two kinds of fields—electric and magnetic—to line up tiny flakes and wires inside a lightweight foam. Rotate the foam and su

Lightweight SiC Aerogels: A New Way to Insulate in Harsh Conditions

January 21, 2025

Have you ever wondered how to keep things cool in super-hot places? Scientists have found a new way using tiny silicon carbide fibers. They started with light, foam-like carbon tubes and turned them into even lighter aerogels. These aerogels can handle extreme temperatures, keep heat out, and bounce
