Ultra-thin nanowires can trap electron 'twisters' that disrupt superconductors

Superconductor materials are prized for their ability to carry an electric current without resistance, a valuable trait crippled or lost when electrons swirl into tiny tornado-like formations called vortices. To keep supercurrents flowing at top speed, scientists have figured out how to constrain troublesome vortices by trapping them within extremely short, ultra-thin nanowires.
