|NIF: US lab takes further step towards nuclear fusion goal|
By Paul Rincon

US physicists have confirmed that they achieved a stage in nuclear fusion called "burning plasma" last year.
There's a longstanding effort to crack fusion power because it promises an unlimited source of clean energy.
Burning plasma occurs when fusion reactions become the dominant source of heating in the process, rather than energy introduced from outside.
The stage was seen in experiments carried out at the National Ignition Facility (NIF) in California.
The achievement is described in two papers published in the academic journal Nature.
Existing nuclear energy relies on a process called fission, where a heavy chemical element is split to produce lighter ones. Fusion works by combining two light elements to make a heavier one.
