Staph infections are often localized in the body, yet can be very difficult to treat, both invasively and using antibiotics.

Researchers from Tufts University’s School of Engineering have developed a possible “wi-fi” drug delivery method to treat bacterial infections. Made from silk and magnesium, the remotely controlled implants can dissolve in the body after use.

Washington University researchers have developed a novel “time-reversal” technology that allows for better-focused light in tissue, such as muscles and organs. Phys.org summarizes the research published in Nature Photonics, that describes using a new technology called time-reversed adapted-perturbation (TRAP) optical focusing, which sends guiding light into tissue to seek movement. Check out this video which shows dynamic focusing onto a moving target inside scattering media.

Connecticut’s Westport Library not too long ago acquired two robots, Vincent and Nancy, that will be used to help teach coding and computer-programming capabilities. Take a look!
