Laser-heated nanowires produce micro-scale nuclear fusion

Nuclear fusion, the process that powers our sun, happens when nuclear reactions between light elements produce heavier ones. It’s also happening — at a smaller scale — in a lab. Using a compact but powerful laser to heat arrays of ordered nanowires, scientists have demonstrated micro-scale nuclear fusion in the lab. They have achieved record-setting efficiency for the generation of neutrons – chargeless sub-atomic particles resulting from the fusion process.
