“A tiny particle smaller than a grain of sand ... struck Gaia at a very high speed and at just the wrong angle, damaging the spacecraft’s protective cover,” ESA officials reported in a July ...

This engine converts the random jiggling of a microscopic particle into stored energy. It could lead to significant advances in the speed and cost of computers and bio-nanotechnologies.

An ensemble of just six atoms displays all the signatures of a phase transition expected for a many-particle system. This is the finding of a team led by researchers at the University of Heidelberg, ...

Too much of this particle can cause coughing, bronchitis, and even cancer — how to get it out of your home ...

Except, the truth is, sand is very much remarkable, at least when you stick it under a microscope. “Every time I see sand under a microscope, it’s a surprise,” says Gary Greenberg.

What is particle pollution? Particle pollution refers to a combination of fine solids and aerosols that are suspended in the air. Particles range in size from the tiny to the microscopic.

The highest proportion of particle types is listed first—as in silty clay loam. Sand has large particles, with big pores in between. Clay is microscopic, so the pores are small.

From a jammed-up particle in a microscopic channel to a tiny robot delivering medicine with pinpoint accuracy, the power of the small may soon change the very fabric of your world.
