Bacteria-scale robots that can run for months without human control are no longer a lab fantasy. Researchers have now built fully programmable micro-machines, smaller than a grain of salt, that can ...

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.

As the human race has advanced, we've made the process of creating products extremely efficient. Assembly line factories litter the planet's landscape, mass producing items piece by piece and ...

(Nanowerk News) A Cornell research team has developed a new way to design complex microscale machines, one that draws inspiration from the operation of proteins and hummingbird beaks. The group’s ...

Researchers from Australia’s University of Queensland have made a microscopic “ocean” on a silicon chip to miniaturise the study of wave dynamics. The device, made at UQ’s School of Mathematics and ...

Gears have powered the world for millennia, from clock machines to car engines. But miniaturizing them to microscopic dimensions has stumped engineers for decades. Anything under one-tenth of a ...
