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 ...

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 ...

A new method developed at the University of Warwick offers the first simple and predictive way to calculate how irregularly shaped nanoparticles — a dangerous class of airborne pollutant — move ...
