Quantum physics is (more or less) the science of what happens when very small things interact without the interference of larger, outside forces and energies. So in order to make many quantum-mechanical experiments work, researchers need to cool small groups of particles way, way down — to the point where heat doesn’t let atoms jiggle. Researchers have long used lasers to slow particles down, sapping their energy. But a new technique, using magnetic fields to trap molecules in place before laser-slowing them, takes that method a step further and works for many more kinds of molecule. In an early experiment with this technique, researchers at Imperial College London cooled a molecule of calcium monofluoride to 50 microkelvin — 50 millionths of a degree above absolute zero.
