Teaching robots to fly like birds

Mar 24, 2026 Electricity-driven materials replace motors and gears to power bird-like drone wings that flap, twist and morph, opening the door to simpler, lighter flapping-wing aircraft. (Nanowerk News) A bird banking in a crosswind doesn’t rely on spinning blades. Its wings flex, twist and respond instantly to its environment....

Atomic jitters power a new kind of probabilistic AI chip

Mar 24, 2026 Thermal noise in magnetic tunnel junctions, usually suppressed, now serves as a tunable source of randomness for Bayesian neural networks with dramatic efficiency gains over silicon. (Nanowerk Spotlight) In most of electronics, noise is waste. Every electronic component generates small, unwanted random signals caused by the thermal...

Why black holes hit the brakes on growth

Mar 24, 2026 Astronomers have an answer for a long-running mystery in astrophysics: Why is there much less growth of supermassive black holes today than in the past? (Nanowerk News) Black holes just can’t feast like they used to. That’s according to a new study from a team of astronomers...
