   Carving a new path forward for compact fusion vessels

Summary:
  Can plasma be sufficiently heated inside a tokamak using only microwaves?
  New research suggests it can! Eliminating the central ohmic heating coil
  normally used in tokamaks will free up much-needed space for a more compact,
  efficient spherical tokamak.

Not so much carving a new path as looking for one. Maybe be gyrotrons can heat the plasma enough, but planing to do experiment which can test whether they can isn't exactly carving a new path - more just looking at a possible new path.

Bye bye ITER and that otehr fusion attempt mayonaise thing

   Researchers dig deeper into stability challenges of nuclear fusion -- with mayonnaise
 Now all I am waiting for is a 10 year old kid doing a better than break even fusion experiment in its parents kitchen...

You may have to wait a long time. Mayonaise may exhibit Rayleigh-Taylor instability, but the lessons it might be able to impart would be difficult to translate into totomak design.
