A conflict-driven reroute of international ships exposed how dramatically cleaner fuel reduces cloud formation.

The climate is changing and nowhere is it changing faster than at Earth's poles. Researchers at Penn State have painted a ...

If you look up at the sky on a clear day, chances are you'll notice thin, white clouds—also known as contrails—following ...

Fangqun Yu's advanced model simulates contrail formation, proposing ice-nucleating particles to reduce their climate impact ...

When attacks disrupted shipping lanes in the Red Sea, few scientists imagined the effects would reach the clouds over the ...

Global shipping rules that quietly cleaned up one of the world’s dirtiest fuels are now reshaping the clouds that hang over the Atlantic. By stripping sulfur out of marine fuel, regulators have ...

South Florida's air may not be as clean as it seems. Invisible yet all around, PFAS — the so-called "forever chemicals"— drift silently through the ...

A single green laser, a glass bead smaller than a bacterium and a lab in Austria are helping you see lightning in a new way.

A new study suggests that adding a tiny amount of ice-nucleating particles into aircraft engine exhaust could make contrails far less harmful by shortening their lifespan.

The chemical interaction between air pollutants and sea salt particles can have effects on air quality, according to the ...

A new paper published in Physical Review Letters explains how a water jet breaks up into unstoppable droplets. Physicists ...
