Experiment would test cloud geoengineering as way to slow warming

Even though it sounds like science fiction, researchers are taking a second look at a controversial idea that uses futuristic ships to shoot salt water high into the sky over the oceans, creating clouds that reflect sunlight ...

Tiny airborne pollutants lead double life: study

University of British Columbia and Harvard researchers have provided visual evidence that atmospheric particles -- which are ubiquitous in the atmosphere, especially above densely populated areas -- separate into distinct ...

Pollution weakens monsoon's might

(Phys.org) -- Over 1.5 billion people in South Asia depend on the summer monsoon rains. Now, pollution exhaust threatens this primary water source for crops and daily living, according to new research at Pacific Northwest ...

Scientists study how water condenses to form clouds

Researchers at the University of Bristol with collaborators from ETH-Zurich have shown that the rate of condensation of water on organic aerosol particles in the atmosphere can be very slow, taking many hours for a particle ...

Is it snowing microbes on Enceladus?

There's a tiny moon orbiting beyond Saturn's rings that's full of promise, and maybe -- just maybe -- microbes.

Unexpected ice-formation mechanism

(PhysOrg.com) -- Extremely hydrophobic materials cause water to roll right off objects that have been coated with them. Up to now, it was assumed that aircraft or wind turbines coated in such a way did not ice up as easily. ...

Slow road to stability for emulsions

By studying the behavior of tiny particles at an interface between oil and water, researchers at Harvard have discovered that stabilized emulsions may take longer to reach equilibrium than previously thought.

Vacuum-like device makes cellular exploration easier

It's a bit of a challenge. But, imagine a microscopic jet vacuum cleaner, the size of a pen nib that hovers over cell surfaces without ever touching them. Then imagine that the soap in the cleaning solution is replaced with ...
