Higher density, yes, but at the cost of lower temperatures. So not as good. Nice but old new. With painfullll advertisement.

Through a new process called plasma-wall self organisation, the CAS researchers were able to keep the plasma stable at unprecedented density levels.
The latest breakthrough was detailed in the journal : Science Advances (https://www.science.org/doi/10.1126/sciadv.adz3040 )in a study titled ‘Accessing the density-free regime with ECRH-assisted ohmic start-up on EAST’.

When your result breaks the laws of physics, you need to check your measurements and maths just to be sure. Better yet, have others do it for you.

This isn't a physics breaking finding. It's breaking the Greenwald density limit in tokamaks. Some other types of fusions reactors can go above this limit by 2-5 times.

In this case they're getting past that limit in the Chinese reactor. We had/have a limited understanding of exactly why this limit exists so hopefully these guy's research can help us figure out a way to get past the limit and achieve higher energy production.

Gotta love science reporters. "Thought to be impossible."

"A 747 jet took off from New York's Kennedy airport this morning, accomplishing a feat once thought to be impossible."

Ah yes, technically correct

Well, I guess this puts it right about 30 years out now.
