When a viscous fluid, such as a jar of honey, is stirred and then unstirred, the contents return to their starting points. However, according to research by a team of physicists headed by New York ...

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 ...

Egg yolk may appear runny and uniform, but on the nanoscale, it is one of the most crowded biological fluids in nature.

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

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

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 ...

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 ...

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 ...
