Researchers at the National Institute of Standards and Technology (NIST) have demonstrated a solid-state refrigerator that uses quantum physics in micro- and nanostructures to cool a much larger object to extremely low temperatures.
Pentagon-supported physicists on Wednesday said they had devised a “time cloak” that briefly makes an event undetectable. It’s one thing to make an object invisible, like the Romulan Cloaking device from Star Trek. But scientists have made an entire moment in time impossible to see. They have invented a time masker. Think of it as [...]
