50 years ago, superconductors were warming up
Superconducting temperatures have risen by about 250 degrees since the 1970s, but are still too cold to enable practical technologies.

Superconductor research surges forward despite controversy over stunning claims
After retractions from Ranga Dias’ group, high-pressure physicists are feeling the squeeze, fearing the controversy will tarnish other research.
- Physics
A controversial room-temperature superconductor result has now been retracted
The retraction by Nature is the third for beleaguered physicist Ranga Dias, who still stands by his claim of a room-temperature superconductor.
- Physics
Is this the superconductor of scientists’ dreams? A new claim faces scrutiny
It’s big, if true: transmitting electricity with no resistance at room temperature and moderate pressure. But controversy dogs the team making the claim.
- Physics
Despite a retraction, a room-temperature superconductor claim isn’t dead yet
A high-profile retraction called a superconductivity result into question. But a new experiment appears to support it.
- Quantum Physics
Quantum computers braided ‘anyons,’ long-sought quasiparticles with memory
Particle-like quantum states called non-abelian anyons remember being swapped and could be useful for protecting information in quantum computers.

Can room-temperature superconductors work without extreme pressure?
The next generation of materials that conduct electricity with no resistance could shrug off the need for high pressure and low temperatures.
- Physics
The first room-temperature superconductor has finally been found
A compound of carbon, hydrogen and sulfur conducts electricity without resistance up to 15° C, but there’s a catch: It works only under high pressure.
