Rockabilly earrings
These were made of gold and glass in Carthage sometime from 300-100BC.
Currently in the the metropolitan museum of art.
A high temperature superconductor!
Last Thursday some Korean researchers released a pre-print paper that they'd discovered a high temperature superconductor - and by high temperature they mean above the boiling point of water. Furthermore the recipe was not exotic or difficult to make so it started a race as labs around the world rushed to try to replicate their results.
Derek Lowe has a good overview of how this has progressing. and I've been watching this lab leaderboard as people try to reproduce
I haven't really seen this in any of my non-technical feeds so I don't know how much people realize what a world changing event a room temperature superconductor would be - I've seen comparisons to the invention of the transistor.
The past thirty years efforts to produce a 'high-temperature' superconductor meant -200C and breakthroughs have pushed this up by 5-10 degrees at a time. LK-99 seems to push this temperature up to 127C.
The skeptics are calling this a repeat of the cold fusion claims but the scientists behind it continue to put out more information - basically staking their entire careers on this claim. It's super exciting to watch unfold in real time and the possibilities that we might be able to manufacture this stuff are dazzling.

Update:
The material scientists did some work and discovered ferrous impurities in the samples made it look like it was diamagnetic. The authors of the original paper still claim this mixture could work but their claims have largely been dismissed. I still hope they prove everyone wrong.
