Every time I write about particle physics, I encounter a moment of uncertainty about a quantity that, at first glance, ought to be clear. How many kinds of elementary particles should I say there are?

Doja Cat took to X on Wednesday to request that the platform’s billionaire owner, Elon Musk, reinstate the “audio post” feature. It’s not likely the Grammy winner will get her way, however, because ...

PM 2.5 is made up of tiny airborne particles no larger than 2.5 micrometers—about 30 times thinner than a strand of human hair. Just like any other particulate matter smaller than 10 micrometers, PM 2 ...

Stardust Solutions says its tiny spheres can reflect the sun’s rays without harming people or the environment. Critics say private companies have no business altering Earth’s atmosphere. An enclosed ...

The pressure produced by a single particle can now be measured for the first time, thanks to a device that uses a tiny bead held in place by a laser. It is so sensitive that researchers hope that it ...

In short: X-Energy raised $1.02 billion in the largest nuclear IPO on record, pricing at $23 (21% above range) on the Nasdaq, with shares surging 31% on opening to imply a $12 billion market cap. The ...

A pair of rare particles produced in high-energy proton collisions may be the clearest evidence yet that mass can emerge from empty space. The finding could shed light on one of the biggest puzzles in ...

When you drill down into the very fabric of reality—where elementary particles make up the matter that is you and me and everything around us in three-dimensional space—things get divided nicely into ...

Scientists discovered “magic” top quarks at CERN’s Large Hadron Collider, demonstrating how the facility has evolved to support quantum computing research. Researchers at ATLAS observed ...

A team of researchers based in Norway and Japan might soon have you walking on desert sand, no matter how far from the dunes you live. This group of engineers has developed a method to transform it ...

Quantum physics paints a strange picture of the world, one filled with spooky connections, unsettling uncertainties and—perhaps oddest of all—particles that spontaneously spring into being from the ...

Indoor air quality has become an urgent concern in recent times, as we spend a considerable amount of time inside our home. Advances in measurement technologies have revealed that small, otherwise ...
