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 ...

What does this have to do with Von Karman vortices? Read on and it will be revealed. The term “vortex” is simply defined as a mass of whirling fluid or air, especially a whirlpool or whirlwind.

These observations provide the first detailed view of how bacterial swarm vortices gradually lose their ... valuable for developing active fluid-based systems on a microscopic scale that exploit ...

There are moments in the history of human thought when a simple realization transforms our understanding of reality. A moment ...

P. R. Tong and colleagues show that thermal excitation can achieve this and is an effective way to control polar topological states, including solitons, waves, and vortices. See Tong et al.

Turbulence is a “violent or unsteady movement of air or water, or of some other fluid”, according to ... the Flightright website shares that “air vortices at lofty heights” are responsible ...

Researchers are investigating fluid-robot interactions at these scales, motivated by fish that use vortices to save energy. Onboard sensing, computation, and actuation are essential for effective ...

Vector, scalar, and hybrid electromagnetic toroidal vortices. Recently, a major breakthrough in the field of optical toroidal vortices has been achieved and published in Science Advances [11(8 ...

Now, the ‘Ultrafast & Twisted Photonics’ research group at the Max Planck Institute for the Science of Light (MPL), Erlangen, Germany, has developed a new hollow-core fiber which selectively guides ...

Today through Monday an upper-level trough will move across the region today. Most locations will remain dry today with ...
