Last year, graduate student Dennis Becker watched from a safehouse as the MAIUS-1's sounding rocket took off from a launch facility in the Swedish Arctic. But after repeated delays from snow and wind, he wouldn’t know for a few days whether the rocket’s payload survived.

When the ambitious experiment dropped back to Earth after spending six minutes in space, clouds made a helicopter retrieval impossible, and the project sat for days alone in the Swedish tundra, where the temperatures dropped to -30C.  

High-temperature electricity without resistance could revolutionise electronics. It could take less energy to move electric charge, meaning better-performing, more-efficient electronics that are cheaper to run. It could cut down on energy costs, and might even help researchers realise better quantum computers. Scientists have gotten a step closer with a little "magic" twist.

To the best of our knowledge, we humans can only experience this world in three spatial dimensions (plus one time dimension): up and down, left and right, and forward and backward. But in two physics labs, scientists have found a way to represent a fourth spatial dimension.
