Fusion power — the process that keeps stars like the Sun burning — holds the promise of nearly unlimited clean power. But scientists have struggled for decades to make it a practical energy source.

Now, laser scientists say a machine learning breakthrough has smashed the standing record for a fusion power yield. It doesn’t mean fusion power is practical yet, but the prestigious journal Nature called the result “remarkable” and wrote that it has “major implications” — so, at the very least, it’s another hint that the long-deferred technology is starting to come into focus.
