Researchers beat the quantum-mechanical fluctuations in an atomic clock by linking many atoms into an entangled quantum state and pushing the fluctuations into a realm that doesn’t influence the time measurement.

Drops of water striking a bed of grains can leave a wide range of crater shapes and sometimes a bigger impression at low and high impact speeds than at medium speeds. The work may help geoscientists identify ancient formations.

The patterns in two spinning tanks of fluid representing different parts of the Earth’s atmosphere can synchronize with only a small amount of thermal coupling, suggesting that heat flow can transmit weather cycles over long distances.

The world’s first free electron laser, a type of laser able to operate from the microwave region of the spectrum all the way up to x rays, was reported in 1977, following an important precursor the year before.

The turbulent atmosphere is better than an equivalent glass fiber when it comes to preserving quantum information in long-distance light signals, according to a new analysis. For brief moments, light can propagate relatively undisturbed.
