Back when I was a Catholic-school kid in northern Wisconsin, my school lessons briefly focused on the metric system. This was ...

Gears have powered the world for millennia, from clock machines to car engines. But miniaturizing them to microscopic dimensions has stumped engineers for decades.

Recently, researchers from Yale University may have made a dent in that inefficiency. They successfully tested a novel way to ...

Ultrafast laser processing creates silicon surfaces that absorb nearly all infrared light and remain stable under heat and ...

As microplastics and their smaller, even more insidious counterparts, nanoplastics, have increasingly permeated the environment and our bodies, one of the key challenges facing researchers has been ...

Researchers at the University of Gothenburg have made light-powered gears on a micrometer scale. This paves the way for the smallest on-chip motors in history, which can fit inside a strand of hair.
