A Small But Promising Step

According to this (gated) report in Science Express, scientists at Lawrence Livermore have managed to fuse hydrogen nuclei by firing 192 lasers into a cylinder containing deuterium and tritium, releasing far more energy than that required to spark the ignition. This is a small, but significant step on the road to potentially self-sustaining fusion reactions. Still a long way to go.
