Magnetic version of electricity, called magnetricity, just recently discovered.Magnetic version of electricity, called magnetricity, just recently discovered.

It is unlikely to become an immediate replacement for electricity because the crystals have to be cooled to below minus 272.15C — just above absolute zero — to be conducting.

Always wanted to make your very own ferrofluid? This post is for you.Always wanted to make your very own ferrofluid? This post is for you.

Controlling the shape of ferrofluids and then 'freezing' them in place could be another tool for inexpensive desktop fabrication. Combining two unusual uses of magnetic fluids invites further empowerment for the maker.

NASA figures out a way to levitate mice using superconducting magnets.NASA figures out a way to levitate mice using superconducting magnets.

Scientists have previously managed to levitate frogs and grasshoppers, but mice are more useful test subjects because their physiology is closer to humans.
