The first endovascular technology that can explore capillaries

At EPFL, Lucio Pancaldi, a Ph.D. student, and Selman Sakar, an assistant professor, have harnessed hydrokinetic energy (mechanical energy resulting from the motion of liquids) to get an instrument into places in the human ...


Microscopic robots 'walk' thanks to laser tech

A Cornell University-led collaboration has created the first microscopic robots that incorporate semiconductor components, allowing them to be controlled—and made to walk—with standard electronic signals.
