#185 — exciting news for Arindam Banerjee

South Korean scientists have created a room-temperature
superconductor (that doesn't require huge pressure).
This has been claimed before, but claims were withdrawn
due to experimental error (probably fraud).
If can be mass-produced, would solve a lot of problems.
Doomsday can gets kicked down the road quite a few years.
(pre-print, yet to pass peer review)

Researchers are now working to replicate the Korean team’s work, and
analysts say their findings will emerge within weeks. Meanwhile, Lee
told Yonhap that the team has already requested an international
journal to review their findings. They “will be verified through peer
evaluation,” Lee said.
Physicists have been hunting for a room-temperature, ambient-pressure
superconductor for decades. Such a material would be a game-changer
for electronics and global energy systems, and could help develop
technologies ranging from long-lasting batteries to levitating trains.

It may turn out to be a lab curiosity. There are quite a few 
superconductors that break down with high current or magnetic field, so 
are not practically useful for anything. So we still need liquid helium 
for an MRI or Large Hadron Collider.

Also room temperature superconductors that only work under
extremely high pressure like this from 2020:
https://www.vice.com/en/article/5dpmz8/scientists-have-created-the-first-room-temperature-superconductor

This one claims to work at normal pressures and temperatures
though. The research paper is here:
https://arxiv.org/pdf/2307.12008

Or, more excitingly, hover boards! So you thought e-scooters were
dangerous?...

Might be pretty handy for fusion reactor development too.

There's more context about this research on Wikipedia:
