"It seemed like nobody wanted to touch it," says Leslie, a microplastics researcher in the Netherlands whose team was the first to detect these particles in the human bloodstream several years ago.

For the first time, scientists have observed a collection of particles, also known as a quasiparticle, that's massless when moving one direction but has mass in the other direction. The ...

Their new study, published in November in the journal Environmental Science and Technology: Air, showed that microplastics function as ice-nucleating particles, tiny aerosols that promote the ...

Aerial observations and experiments with a simulated atmosphere show that isoprene, a gas emitted by trees, is a precursor of particles in the upper atmosphere. The findings could help to improve ...

It seems that the smallest possible unit of charge is that of an electron – all other naturally occurring particles only have multiples of this. In nature, you can find charges of -1 or +3 or -2 ...

In 1929 the American astronomer Edwin Hubble discovered that the distances to far-away galaxies were proportional to their redshifts. Redshift occurs when a light source moves away from its observer: ...
