In a twist on conventional wisdom, researchers have discovered that in ocean-like fluids with changing density, tiny porous particles can sink faster than larger ones, thanks to how they absorb salt.

Neutrinos as physicists understand them cannot constitute dark matter. The Standard Model explains how the basic building blocks — fundamental particles — and three of the four known forces created ...

Materials scientists are measuring the rolling friction of tiny, micrometer-sized particles. These measurements permit them to better understand everyday products such as concrete. For the first time, ...

Dipangkar Dutta receives funding from US Dept. of Energy and NSF. A clever mathematical tool known as virtual particles unlocks the strange and mysterious inner workings of subatomic particles. What ...

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 ...
