"Scientists have produced superheated gas exceeding temperatures of 2 billion degrees Kelvin, or 3.6 billion degrees Fahrenheit.

 

This is hotter than the interior of our sun, which is about 15 million degrees Kelvin, and also hotter than any previous temperature ever achieved on Earth, they say.

 

They don't know how they did it."

The article said the machine was releasing more energy than was put in, suggesting fusion was taking place. However it is my understanding that iron is the highest atomic number element whose formation from fusion of lighter isotopes results in a net release of energy. To fuse iron nuclei requires a net input of energy. This explains why heavier elements than iron are relatively rare. All were formed when stars exploded in the distant past as supernovae.
