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

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, ...

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 ...

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 ...
