Scientists have developed a device that could potentially prevent skin infections by "zapping" harmful bacteria with electricity. The patch, called BLAST, delivers harmless electrical currents into the skin, stopping disease-causing bacteria in their tracks. Early experiments on pig skin show promising results, but human testing is needed to confirm its effectiveness.
