How you can control lab-grown heart cells with a remote control light

University of California San Diego researchers have created a technique that speeds up and slows down human heart cells that are being grown in a dish on command by shining light on them and varying the intensity. The heart cells are being grown in graphene which turns light into electricity, a more realistic environment that

Turns out graphene can fight bacteria on implants

Graphene flakes that are arranged like spikes can kill bacteria and stop infections during implant surgery procedures, according to new research from Chalmers University of Technology in Göteborg, Sweden. Bacteria moves around the body in fluids like blood looking for an area to stick to. Once they find a place, the bacteria starts to grow

Stem cells and graphene can regenerate nerves: Here’s how

Iowa State University researchers have developed a nanotechnology that turns mesenchymal stem cells into Schwann cells for nerve regeneration. Schwann cells form sheaths around axons on nerves and promote regeneration of axons. They also produce substances that help promote the health of nerve cells. Both actions are helpful for researchers who are looking to regenerate

Solar powered skin could make prosthetics better: Here’s how

University of Glasgow engineers are using the sun to power artificial skin and return a sense of touch in amputees with prosthetics. The engineers previously developed an electronic skin made of graphene that covered prosthetic hands. They’re now using the unique properties of graphene to power new artificial skin. Graphene is a single-atom thick material
