Scientists may have found a way to treat infections that works better than antibiotics. The solution is not another drug, but a feat of physics: cold plasma.
Before you ask whether that is an oxymoron, let me explain. Cold here is not cold in the Arctic sense; rather the opposite of scalding hot. Plasma — an ionized gas sometimes called the fourth state of matter — typically exists at thousands of degrees Celsius, and hot plasmas are regularly used to sterilizing surgical equipment.
