Alexandria Johnson does hard science on the most nebulous of subjects: clouds. As an atmospheric scientist and assistant professor of practice in Purdue University’s College of Science, she studies ...

Miriam Freedman (left), professor of chemistry at Penn State, and Heidi Busse, a graduate student at Penn State, studied the freezing activity of four different types of microplastics to see how they ...

As part of the international CLOUD project at the nuclear research centre CERN, researchers at PSI have identified so-called sesquiterpenes – gaseous hydrocarbons that are released by plants – as ...

Clouds form when water vapor—an invisible gas in the atmosphere—sticks to tiny floating particles, such as dust, and turns into liquid water droplets or ice crystals. In a newly published study, we ...

An international team led by CU Boulder researchers has cracked the chemical code driving the formation of iodine particles in the atmosphere, revealing how the element contributes to increased cloud ...

MOLINE, Ill — Perhaps one of the strangest appearing things in the sky you'll ever witness, this unique cloud formation comes in different sizes and shapes. It is, however, usually caused by the same ...

An interesting phenomenon unfolded Monday in the sky over Houston as nearly perfect rows of clouds were spotted. Video submitted to us by a subscriber showed the unmistakable appearance of what are ...

A picture of a cloud formation in Virginia that resembles rolling waves is going viral. Weather experts say this type of cloud formation, which was spotted in over Smith Mountain Lake near Roanoke, is ...

Microplastics are turning up in unusual places increasingly often as they filter into nearly every facet of life on Earth. They’ve been discovered in drinking water, food, air and even in blood. Now, ...

Plants release gaseous hydrocarbons called sesquiterpenes. Scientists have now found that sesquiterpenes are a significant factor in cloud formation. Right now, there is still debate about how much ...

Stratocumulus clouds may not be the showiest puffs in the International Cloud Atlas, but they are the workhorses of the atmosphere. The low, flat decks of clouds—also known as marine layers—cover over ...
