It is commonly assumed that tiny particles just go with the flow as they make their way through soil, biological tissue, and other complex materials. But a team of Yale researchers led by Professor ...

Accurately modeling irregularly-shaped particles isn’t easy, but a new study found a way to improve a century-old idea.

A pioneering method to simulate how microscopic particles move through the air could boost efforts to combat air pollution, a study suggests. A pioneering method to simulate how microscopic particles ...

The research underscores growing concerns about how ultra-small plastic particles move through marine ecosystems and into foods people rely on.

When rats breathed in nano-size materials at a concentration routinely inhaled by factory welders, the tiny particles followed a rapid and efficient pathway from the nasal cavity to several regions of ...

Increased use of ventilation and air cleaners, designed to mitigate the spread of viral infections in hospitals, is likely to have unpredictable effects and may cause viral particles to move around ...
