The search for electron-hole liquids gets warmer

An electron-hole liquid is a unique collective quantum state formation in semiconductors where free charges can condense into a droplet. These droplets have interesting uses for laser-controlled circuits based on light beams instead of wires. Unfortunately, electron-hole liquids normally only exist in extremely cold environments, and aren’t practical for real devices. But what if these droplets could instead form as the…

Facebook Blocks All News In and From Australia

A new planet next door?

Astronomers have spotted “something” near Alpha Centauri A, in the star system nearest our Earth and sun. If it turns out to be a planet, it’ll be the first time a planet has been directly imaged within the habitable zone of a star.
