UC San Diego Physics Professor Jorge Hirsch...
...joins Professor Brian Keating to discuss recent claimed a breakthrough in high-temperature superconductors, including claims they work at near ambient pressure and temperature.
Here come cheap magnetic levitating trains, low-loss power distribution, free MRI scanners in every clinic…. Or not?

Since the discovery of superconductors in 1911 by Heike Kamerlingh Onnes, earning the 1913 Nobel Prize in Physics, they have been the subject of much fascination and inquiry. Some of the greatest minds in physics have grappled with how superconductivity works to drive electrical resistance to 0.
The 1972 Nobel prize in Physics was awarded to John Bardeen, Leon Neil Cooper, and John Robert Schrieffer "for their BCS theory of superconductivity. Now the race is on to get the highest temperature superconductor possible; another Nobel Prize was awarded just for getting the temperature up to 35K or -396 Fahrenheit!
Superconducting has remained impractical, until now... Maybe! The HUGE claim: zero resistance, at temperatures up to 65 degrees Fahrenheit. Is it a scientific breakthrough, or is it very probably fraud?

Key Concepts:
- Superconductors are materials that conduct electricity without resistance.
- Room-temperature superconductors would have a wide range of potential applications, including in power transmission, medical imaging, and quantum computing.
- The researchers at the University of Rochester claim to have discovered a room-temperature superconductor.
- However, there are some concerns about the validity of the research.
- It is too early to say whether the discovery is a breakthrough or a fraud.
