Einsteinium chemistry captured
The creation of a rare molecule offers a peek at how heavy atoms interact with other elements.
Pauli crystals make their experimental debut
When a few ultracold atoms are repeatedly trapped and imaged tens of thousands of times, self-organized patterns emerge out of the quantum blue.
A tabletop waveguide delivers coherent x rays
The layered anode emits bright, directed beams without the need for mirrors or large-scale accelerators.

Liquid metals at room temperature
Emerging applications and studies utilize gallium-based alloys for their unique properties.
Medieval weather prediction
Meteorological practices that developed in the first millennium did not die in the Middle Ages but were radically improved with an international science of weather forecasting.
The squeezes, stretches, and whirls of turbulence
Fluid turbulence generates a chaotic soup of strongly nonlinear features that are hard to mathematically describe and model. A recent theoretical simplification brings fresh insight.
