Chinese researchers have unveiled a new rare earth alloy so cold and efficient it could upend decades of reliance on helium-3 and send shock waves through the global race for quantum computers or ultra-sensitive detectors.
A mini-fridge built with the alloy has achieved temperatures extremely close to absolute zero using no moving parts. And it comes at a time when the US Defence Advanced Research Projects Agency (DARPA) is actively hunting for exactly such a technology.

And I think this is the more recent one being talked about https://www.nature.com/articles/s41467-025-68278-z
Had to go through like 5 sites to find one that actually mentioned a name then did a pubmed search on that. I’m not certain because this ain’t my field. What happened to citing your sources?!
