Breakthrough in Controlling DNA-Based Robots

Researchers use magnets to move tiny nano-devices faster than ever before. Researchers have devised a magnetic control system to make tiny DNA-based robots move on demand—and much faster than recently possible. In the journal Nature Communications, Carlos Castro and Ratnasingham Sooryakumar and their colleagues from The Ohio State University report that the control system reduced

Physicists Take First Step Toward Cell-Sized Robots

An electricity-conducting, environment-sensing, shape-changing machine the size of a human cell? Is that even possible? Cornell physicists not only say yes, but they’ve actually built the “muscle” for one. The team has made a robot exoskeleton that can rapidly change its shape upon sensing chemical or thermal changes in its environment. And, they claim, these
