Researchers develop spray patch to repair damaged hearts, with a healthy dose of electricity

Spray-on solutions have found a place in green technology and even in transmitting radio waves, and they're no strangers to medical research, either. Researchers at the British Heart Foundation are working on a bioelectric spray composed of heart cells to help mend that most vital of organs. Because the cells need to be extremely thin to form a sheet of heart tissue, they are passed through a conductive needle that charges them with up to 30,000 volts. Exposing the cells to an electric field turns the solution into small droplets, which in turn form the cardiac sheet. The scientists can also add other types of cells to create "three-dimensional" tissue, which can be grafted onto injured hearts or sprayed onto scar tissue to help patients' tickers pump more strongly. As is so often the case, the next step will be testing the technology on animals, and the project's ultimate goal is to use this spray-on solution rather than making patients wait for donor hearts.

Researchers use virus’s rogue traits to create electricity from motion

berkeley-labs-piezoelectrics-from-virus

Viruses are the swarming bullies of biology, but it turns out their alarming self-replication could one day power your iPod. We've seen them in batteries before, but researchers at Berkeley Labs have now coated electrodes with modified M13 bacteriophage, a harmless bacteria-eating virus, to create the first ever organic piezoelectric material -- which can convert force to electricity. The team explained that such a substance would be non-toxic, organize naturally into thin layers and self-regenerate, giving it a possible advantage over chemical options. In theory, by attaching a thin film of it to your shoes, power could be generated when walking, lending volts to the myriad electronics we pack around nowadays. To see a finger-powered video demo of our frequent-enemies making themselves useful for a change, stroll on past the break.
