Scientists have reproduced last year's nuclear fusion breakthrough

Scientists at a federally funded research center in the US have successfully conducted a second nuclear fusion reaction experiment that resulted in a net energy gain. The Lawrence Livermore National Laboratory (LLNL) said scientists at the National Ignition Facility (NIF) generated a higher energy yield than in their December breakthrough , as Reuters reports. The nuclear fusion approach is very similar to the process that results in stars being able to emit light and heat. The scientists used a...
