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 ...

The zinc-air batteries, which can generate up to a volt, are as thin as a human hair. A battery designed by MIT chemical engineer Michael Strano and colleagues could make it possible for cell-size ...

A team of scientists at Nanyang Technological University, Singapore (NTU Singapore) has developed grain-sized soft robots that can be controlled using magnetic fields for targeted drug delivery, ...
