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 ...

Physicists may have just cracked open a hidden side of the quantum world. For decades, every known particle was thought to belong to one of two categories — bosons or fermions — but researchers have ...

Solids, liquids and gases. In a solid like this brick, the particles are regularly arranged touching their neighbours and move only by vibrating. This explains why solids have a fixed shape. In a ...

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 ...

In November, scientists arrived at the South Pole in planes outfitted with skis to pull off a construction project seven years in the making. They had a short summer window — November to early ...

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 ...

Physicists have long relied on the idea that electrons behave like tiny particles zipping through materials, even though quantum physics says their exact position is fundamentally uncertain. Now, ...

A clever mathematical tool known as virtual particles unlocks the strange and mysterious inner workings of subatomic particles. What happens to these particles within atoms would stay unexplained ...

A new video podcast from GBH and the producers of NOVA, hosted by Hakeem Oluseyi. Should we bring back extinct species? Are we missing a fundamental law of nature? What can ancient fossils tell us ...
