A combination of sewage overflows and coastal winds could be sending billions of airborne microplastic particles into the ...

An invisible force has long eluded detection within the halls of the world’s most famous particle accelerator—until now.

Ultrafine particles are aerosols less than 0.1 micrometers, or 100 nanometers, in diameter — about one-thousandth the width of a human hair. Due to their tiny size, they can be easily inhaled into the ...

Ultrafine particles are approximately one-thousandth the width of a human hair. But because of their tiny size, they are easily inhaled – and typically more dangerous than larger particles.

Ultrafine particles are aerosols less than 0.1 micrometers, or 100 nanometers, in diameter — about one-thousandth the width of a human hair.

During the experiment, airborne particles ejected from the toilet traveled at speeds of up to 6.6 feet per second and reached 4.9 feet above the toilet within eight seconds, the scientists found.

WASHINGTON: Small coronavirus respiratory particles may remain moist and airborne for a longer time and travel to greater distance than previously thought, a study conducted in a laboratory ...

A Rutgers study has detected tiny airborne particles containing RNA from the SARS-CoV-2 that causes COVID-19, both inside and outside of the rooms in which infected people were self-isolating at ...

A new study from the University of California, Davis, and the Icahn School of Medicine at Mount Sinai confirms that surgical masks effectively reduce outgoing airborne particles from talking or ...

The pollen grains released by wind-pollinated plants are 17-58 μm while, according to a WHO document, "dusts are solid particles, ranging in size from below 1 µm up to at least 100 µm, which ...
