UC Berkeley physicists used partially entangled atoms identical to the qubits in a quantum computer to demonstrate more precisely than ever before - to one part in a billion billion - that space is uniform in all directions and not squeezed.

Earth's magnetic field is crucial for our existence, as it shields the life on our planet's surface from deadly cosmic rays. It is generated by turbulent motions of liquid iron in Earth's core. Iron is a metal, which means it can easily conduct a flow of electrons that makes up an electric current. ...
