Scientists are exploring DNA-based robots, tiny molecular machines that could one day navigate the body, deliver targeted therapies, and even build nanoscale technologies.

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 ...

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 ...

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 ...
