Organic particles modulate soot mixing in the atmosphere

In the atmosphere, individual soot particles emitted from human activities often encounter and combine with organic material, forming soot-containing particles. A research team led by scientists from the U.S. Department of ...

Swimming bacteria work together to go with the flow

Swimming bacteria can reduce the viscosity of ordinary liquids like water and make them flow more easily, sometimes down to the point where the viscosity becomes zero: the flow is then frictionless.

Unusual thermal convection in a well-mixed fluid

Researchers from Tokyo Metropolitan University, have recently discovered unusual thermal convection in a uniform mixture of high- and low-viscosity liquids. Kobayashi and Kurita found that concentration fluctuations are enhanced ...
