PhysicsScandium superconducts at the highest temperature for a pure element Two independent teams of researchers found that putting the silvery metal scandium under extreme pressure makes it into a superconductor at a temperature higher than any other element on its own 51¶¯Âþ
PhysicsSunlight could cool an atom to its coldest possible temperature Sunlight transmitted through an optical fibre could be used to help cool a single charged atom to a temperature only a few millionths of a degree above absolute zero 51¶¯Âþ
