Egg yolk may appear runny and uniform, but on the nanoscale, it is one of the most crowded biological fluids in nature. Packed with proteins and fats, it serves as a dense storage reservoir for a ...

Microplastics have been detected in semen and ovarian fluid, raising concerns about their potential impact on egg and sperm quality. Experts explain what current research suggests about fertility ...

It is commonly assumed that tiny particles just go with the flow as they make their way through soil, biological tissue, and ...

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 ...

Imagine a "smart fluid" whose internal structure can be rearranged just by changing temperature. In a new study published in ...

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 ...

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, ...

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 ...

Gears have been around for thousands of years, with the first records dating back to 3000 BC. While they have advanced over ...

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 ...
