Vapor-collection technology saves water while clearing the air

About two-fifths of all the water that gets withdrawn from lakes, rivers, and wells in the U.S. is used not for agriculture, drinking, or sanitation, but to cool the power plants that provide electricity from fossil fuels ...

Freeze! New model to protect ships from ice accretion

Researchers from Skoltech (Russia) and their colleagues from SINTEF (Norway) have developed a mathematical model of freezing water droplets moving in cold air. This model is a part of a joint RFBR-supported Russian-Norway ...

Researchers flip how electrical signals move liquid droplets

When medical laboratories analyze blood samples for signs of disease, they sometimes use instruments that rely on a technology called digital microfluidics. The technique uses electric signals to pull tiny droplets of the ...

Researchers create 3-D-printed soft mesh robots

Researchers at North Carolina State University have created 3-D-printed flexible mesh structures that can be controlled with applied magnetic fields while floating on water. The structures can grab small objects and carry ...
