Armed with a quantum magnetometer that reads nuclear spins with incredible precision, scientists hunted for exotic forces that break mirror symmetry. A tandem of rotating lead masses and a cloud of neon atoms improved previous constraints by a thousandfold. The setup works like a miniature gravitati

Defects in diamond turn into ultra-sensitive magnetic sensors. By using a noise subtraction method with two sensors (like hearing with two ears), they registered a magnetocardiogram for the first time in a regular room. Compact and requiring no cooling, they promise low-cost contactless diagnostics.
