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
Understanding how lithium reacts to pressure developed from charging and discharging a battery could mean safer, better batteries. There’s an old saying: “You must learn to walk before you learn to run.” Despite such wisdom, numerous industries skip the basics and sign up for marathons instead, including the battery industry. Lithium ion batteries hold incredible
MIT-developed process could offer nontoxic alternative to environmentally harmful chemicals. Fabrics that resist water are essential for everything from rainwear to military tents, but conventional water-repellent coatings have been shown to persist in the environment and accumulate in our bodies, and so are likely to be phased out for safety reasons. That leaves a big
