The collective motion of bacteria—from stable swirling patterns to chaotic turbulent flows—has intrigued scientists for decades. When a bacterial swarm is confined in small circular space, stable ...

There is a sudden warming about to happen high up in the atmosphere. This warming usually affects the Polar Vortex.

For the first time, scientists have experimentally confirmed that electrons can form tornado-like structures in momentum ...

However, until now, no one knew how to measure them. The breakthrough experiments revealed that the quantum vortex is created ...

This new method describes an experimental concept called ultrafast vortex electron diffraction ... enabling precise tracking of electron motion in both space and time. This method is especially ...

Researchers have experimentally demonstrated a quantum tornado. Electrons form vortices in the momentum space of the quantum semi-metal tantalum arsenide.
