Experiments with small falling particles show that their orientations oscillate—which may help explain the settling of volcanic ash and the formation of snow. 

A detailed experimental analysis explains the forces by which a spinning magnet can cause another magnet to levitate in midair.

A mathematical model shows how increased intricacy of cognitive tasks can break the mirror symmetry of the brain’s neural network.

A laser experiment provides a proof-of-principle test for an alternative fusion concept that uses targets made with liquid fuel rather than conventional frozen fuel.

A curved “laser wakefield accelerator” could boost the acceleration potential of a multistage version of this device.

A spinning plasma ring mimics the rotating structure surrounding a black hole.

The mass-and-spring-like behavior of a water droplet helps explain its ability to seal the leaky pipe from where it came.

A new spin behavior has been found in the light-induced electron emission of tungsten ditelluride.

Fusion researchers received an early holiday present with the confirmed measurement of a laser-induced fusion reaction that produced more energy than it consumed.

Axions that decay into photons could account for visible light that exceeds what’s expected to come from all known galaxies.
