Atmospheric turbulence may promote cloud droplet formation

Clouds form when water vapor in moist packets of air condenses onto atmospheric aerosols, such as particles of dust. The transition from dry particle to liquid water droplet is known as activation. The threshold for activation ...

Electromagnetic water cloak eliminates drag and wake

Researchers have developed a water cloaking concept based on electromagnetic forces that could eliminate an object's wake, greatly reducing its drag while simultaneously helping it avoid detection.

Swirling swarms of bacteria offer insights on turbulence

In the bacterial world, as in the larger one, beauty can be fleeting. When swimming together with just the right amount of vigor, masses of bacterial cells produce whirling, hypnotic patterns. Too much vigor, however, and ...

Langmuir circulation inhibits near-surface water turbulence

In the surface ocean, breaking waves are a major source of air bubbles and turbulent kinetic energy. During the presence of a consistent surface wind, these wave-generated bubbles, along with other surface material like seaweed ...
