By driving the motion of a lattice of atoms in a spiral pattern, researchers produced chiral phonons that turn a paramagnetic material into a magnet. The technique could induce properties that are hard to find in naturally-occurring materials.

The remarkably high efficiency of solar cells made from perovskites has puzzled scientists for nearly 20 years. Now, researchers say they have found an explanation – and it's all due to the "shallowness" of the material's defects.
