On Jan. 18, I was one of millions of Americans scrolling through TikTok when service for the all-you-can-binge video buffet suddenly halted just before a federal government ban went into effect. It was a breathtaking…
Researchers at UT Austin have developed durable sapphire nanostructures that repel glare, dust, and fog, potentially revolutionizing phone screens, glasses, and windshields. Inspired by moth eyes and lotus leaves, the structures are both tough and…
UC Riverside has landed nearly $4 million to lead an ambitious research effort into antiferromagnetic spintronics—a cutting-edge technology that could revolutionize memory and computing. Unlike traditional electronics, this approach leverages the quantum spin of electrons…
The picture shows a standard blue OLED with a width of 15 mm and an emitting pixel width of 2 mm. A polariton OLED would be obtained by replacing the thin films below and above…
Hugues Oyarzabal, one of Europe’s most accomplished surfers and among the first to record spectacular feats from inside the curl of a wave using digital cameras, died on Feb. 21 at his home in Biarritz,…
