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 ...

In biology, many RNA molecules act as sophisticated microscopic machines. Among them, riboswitches function as tiny biological sensors, changing their 3D shape upon binding to a specific metabolite.

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 ...

In the 1960s, most computers took up an entire room. Faster computers now find themselves on the wrists of people all over the world. As devices get smaller, humanity seems to be on track to create ...

(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 ...

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 ...

These photos show the “scooter” (on the left) and “rotator” (on the right). Each micromachine was observed in detail and using motion tracking for 70 seconds at a time over several hours. The scale ...
