Insect-inspired flying robot bounces back after collisions

Flying insects, such as fruit flies, bees, dragonflies and mosquitoes, can dart through narrow spaces and survive collisions with various objects. In contrast, many flying robots fall, suffer damage or even break down when ...

AIs fail to reliably detect AIs in reverse Turing tests

The famous "Turing test" of computer science comes from a 1950 paper written by the British computer scientist (and war hero) Alan Turing. There are many variants, but perhaps the most common involves a human asking questions ...

Seeing Rembrandt through the eyes of a machine

A few hundred years ago, determining whether a painting was created by a master like Rembrandt or a talented copycat depended only on the trained eye of an expert. Then, new tools like X-rays and infrared imaging allowed ...
