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, ...

Bacteria that colonize tiny plastic fragments drifting through the atmosphere can significantly enhance those particles’ ability to trigger ice crystal formation inside clouds, according to research ...

The formation of stars is intricately linked to the complex structure and dynamics of molecular clouds—vast, cold, and dense regions in the interstellar medium that primarily consist of molecular ...

A study published on January 25 in the journal Science shows how the presence in the atmosphere of ultrafine aerosol particles (less than 50 nanometers in diameter) can intensify the cloud formation ...

The teeming life in the Southern Ocean, which encircles Antarctica, contributes to brightening the clouds that form there, according to a new study. The clouds are bright because of their high density ...

New findings significantly alter the prevailing understanding of how marine life influences clouds and may change the way scientists predict how cloud formation responds to changes in the oceans.
