For nearly 50 years, scientists have suspected that microscopic marine plankton play a role in cloud formation over the oceans. Now, an experiment led by the University of Helsinki suggests that it ...

The cleanest chamber ever built is allowing researchers at CERN to track the microscopic processes governing cloud formation, finds Matthew Chalmers Clean climate The CLOUD experiment is sensitive to ...

Aerosol particles in the atmosphere profoundly influence public health and climate. Ultrafine particles enter the body through the lungs and can translocate to essentially all organs, and they ...

This experiment demonstrates how clouds form in our atmosphere through the interaction of warm and cold air. You'll create a miniature version of this natural process ...

Have you ever looked up at the clouds in the sky and wondered how they form? Understanding cloud formation is really important for studying weather patterns and making accurate forecasts. Those clouds ...

When a beam of light passes through a cloud of atoms, photons (particles of light) sometimes appear to spend a negative amount of time there, with light seeming to exit the cloud before it even enters ...

Noctilucent or night-shining clouds are rare, high-altitude clouds that glow with a blue, silvery hue at dusk or dawn when the sun shines on them from below the horizon. These ice clouds typically ...
