Researchers found these weirdly stable 'energy pulses' that can drift through plasma at a snail's pace without falling apart.

Existence of traveling waves for the two-dimensional Zakharov system

The Takeaway
Energy in hot, ionized gas usually spreads out and disappears almost instantly. Finding these 'solitary waves' means we could potentially move concentrated packets of energy through plasma environments, like fusion reactors, much more efficiently than previously thought possible.
From the abstract
Via a fixed point argument, we construct solitary waves for the two-dimensional Zakharov system that travel with any small speed $c \in \mathbb{R}^2$. Moreover, we investigate their asymptotic behavior.
