A Chinese scientist’s viral demonstration shows how simple optics can make body parts vanish, sparking global debate over ...

Neurophos is taking a crack at solving the AI industry's power efficiency problem with an optical chip that uses a composite material to do the math required in AI inferencing tasks.

A functional invisibility cloak is one of those things that physicists keep chasing, and every six months or so we see an update that brings us one step closer to being able to sneak around without ...

For nearly 20 years, physicists and engineers have chased the idea of invisibility. Early efforts focused on hiding objects from light using so-called metamaterials with extreme and often unrealistic ...

The great unappreciated weakness of invisibility cloaks is that they only make things invisible to human eyes. Or x-ray imagers. Or ultraviolet sensors, infrared image analyzers, echo-location audio ...
