Researchers at McGill University in Canada have increased a battery’s energy density by adding a rare-earth metal to an anode ...

It’s not that rare earth elements like neodymium are all that rare geologically; rather, deposits are unevenly distributed, making it easy for the metals to become pawns in a neverending ...

[Seth Robinson] was inspired by the way eddy currents cause a cylindrical neodymium magnet to levitate inside a rotating copper tube, so he cast a spherical copper cage to levitate a magnetic sphere.

The story of neodymium reveals many of the challenges we’ll likely face across the supply chain in the coming century and beyond. Leaving aside meteorites that strike Earth’s surface and ...

Chinese researchers unveil a magnetic microrobot that manipulates droplets 20x faster, enabling precise, residue-free microfluidic tasks.

Chemistry often conjures images of mixing fluids together in beakers, flasks, or test tubes. But often, chemistry happens on ...

Here’s what neodymium can tell us about the next century of material demand. This article is from The Spark, MIT Technology Review’s weekly climate newsletter. To receive it in your inbox ...
