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 ...

What governs the speed at which raindrops fall, sediment settles in river estuaries, and matter is ejected during a supernova? These questions circle around one, deceitfully simple factor: the rate at ...

Imagine a liquid that flows freely one moment, then stiffens into a near-solid the next, and then can switch back with a simple change in temperature. Researchers at the University of Chicago Pritzker ...

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, ...

After years of creating highly specialized software, researchers used supercomputer clusters to finally solve the ...

Compressible micropolar fluid dynamics is an advanced field that extends classical fluid mechanics by incorporating microstructural effects. This framework accounts for both the conventional ...

Engineers at Northwestern University have unveiled the behavior of single microscopic particles when they unite. The findings reveal an enigmatic, perfectly synchronized dance. The research team ...

In a recent study published in Science Advances, an international team of researchers led by Northwestern University have developed a method to trap rolling microparticles in fluid using obstacles ...

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 ...

Even the most mundane tools may bring forth complex truths in microgravity. On October 20, 2025, a set of small metal ball bearings suspended in viscous fluid became the centerpiece of a highly ...

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 ...
