It's a problem with no definitive answer. Experts discover concerning phenomenon lurking in ocean waters: 'The theory is ...

ISS microgravity experiments reveal how particles cluster, helping science on Earth and future space missions.

In this Oct. 20, 2025, photo, tiny ball bearings surround a larger central bearing during the Fluid Particles experiment, ...

A new computational analysis supports the idea that photons (a.k.a. particles of light) colliding with heavy ions can create a fluid of 'strongly interacting' particles. In a new paper, they show that ...

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, ...

The single particle extinction and scattering (SPES) method can accurately determine the material properties and size distribution of individual particles. A broad range of research disciplines could ...

In reliability engineering, few indicators are as consistently revealing as the particles that infiltrate a lubrication ...

To melt a solid, heat it. To freeze a liquid, cool it. It's simple—except when it isn't, because quantum mechanics can flip even the intuitive logic of melting and freezing on its head. Physicists ...

The measuring tip of an atomic force microscope with a specially designed holder in which a spherical particle is “trapped”. Lacquers, paint, concrete—and even ketchup or orange juice: Suspensions are ...
