Scientists have filmed tiny magnetic vortices, called skyrmions, melting out of an organised lattice for the first time, ScienceDaily reports. Watching how they behave could help researchers find new ways to manipulate them.

Why it matters

The possible payoff is brain-like computers built from smaller, more energy-efficient technology. That remains a prospect, not a working computer; still, seeing the vortices change gives researchers a useful handle on an unusual material. It is a small, intriguing step towards computing that borrows more from physics than the usual chip playbook.

Discuss: Should computing research put more effort into brain-like hardware, or is improving conventional chips the more practical route?
