What happened

Leaving gravity behind: Experiment from ISS reveals how particles alter turbulent flow behavior Gaby Clark Scientific Editor Robert Egan Associate Editor After traveling hundreds of miles above Earth and spending months aboard the International Space Station,…

Why it matters

The project, led by assistant professor of mechanical engineering Tyler Van Buren, is designed to study how particles influence turbulent flows.

Common ground

From dust in the air to sand in coastal zones and bubbles at the sea surface, particles can change how flows behave.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
