Antarctic-Temperature Superconductors

New Scientist:

Superconductors have just reached a new high. A material has been shown to transmit electricity with no resistance at the highest temperatures ever: the chilly conditions you might experience in Antarctica.

This is one of those things that sounds less exciting and important than it is, but let’s clear this up right now: every awesome “science fiction made real” thing you’ve seen someone do involving magnets? They were using superconductors that, in general, had to be dipped in liquid nitrogen to function. Getting them to function at higher temperatures makes a lot of things a lot more possible.
