Chinese scientists create world’s coldest alloy. It may surprise DARPA (www.scmp.com)

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.

Anyone got a link to the paper? This article doesn't even mention the author names.

https://www.nature.com/articles/s41586-023-06885-w thats an older one

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. What happened to citing your sources?!

Experts report the alloy was unmoved by the masterful prologue to Pixar's 2009 classic Up.

How cool is it to see the US/'West' getting left behind in so many domains..
