TIME to retire the old soldering iron? In the “atomtronic” circuits shown above, it’s atoms, not electrons, that flow. Previously, atoms have been made to flow from one point to another. To get them to flow round and round in a circuit, Kevin Wright and colleagues at the National Institute of Standards and Technology in Gaithersburg, Maryland, chilled 100,000 sodium atoms until they became a Bose-Einstein condensate – a blob of floating atoms that behaves as a single,
