Unlike everyday objects, quantum particles can be linked over long distances, behaving as one integrated whole, even though they are so widely separated they can’t communicate, even at the speed of light. Einstein hated the idea, which he called “spooky action at a distance.” Physicist Mark Alford explains the logic behind a famous experiment designed to tell whether quantum mechanics is spooky or nonspooky.
Just when we thought we knew it all, scientists have discovered that there are microbes that eat electricity, which is about as strange as people snacking by shoving a finger in an electric socket. What’s more, these microbes are very common. Whenever scientists have searched for electron eaters in the right places, they’ve always found them. They’ve remained invisible so long because they don’t grow well in science laboratories. Arpita Bose describes these fantastic bugs in a new animation.
