The gold particles dissolved in the solution were dragged out of it and deposited as solid grains onto the quartz’s surface. But that wasn’t the end of the story.

A single 1-litre bottle of water could contain 240,000 microscopic plastic particles. The health implications of ingesting plastic are unclear, but early research suggests such particles could ...

Bottled water contains millions of small particles, thousands of which are nanoplastics so tiny they can invade the body’s cells, a study finds.

When earthquakes squeeze quartz crystals, the mineral generates electricity that attracts gold particles. Pierre Longnus via Getty Images Earthquakes may help prospectors strike gold: When these ...

This gold-tinted technique bypasses those photoreceptors by focusing infrared light directly on the nanoparticles, which in turn generate heat that activates the bipolar and ganglion cells.

Health Making a single change can cut your microplastics intake from 90,000 to 4,000 particles per year By Tracy Swartz Published March 5, 2025, 2:03 p.m. ET ...

LHC experiments don’t create large gold nuggets — but some particles within a beam of lead ions can turn into gold for about a microsecond. slowmotiongli/Getty Images ...
