Spotting Earth-like planets is nearly impossible with conventional telescopes, but researchers propose a bold fix: a rectangular design that can separate a planet’s faint glow from its blinding star.

A new technical paper titled “Massively parallel and universal approximation of nonlinear functions using diffractive processors” was published by researchers at UCLA. “Nonlinear computation is ...
