Superconductors promise loss-free electricity, but most only work at extreme cold. Hydrogen-rich materials changed that—yet their inner workings remained hidden because they only exist under enormous ...

Scientists may have spotted a long-sought triplet superconductor — a material that can transmit both electricity and electron spin with zero resistance. That ability could dramatically stabilize ...

If LK-99 is the real deal, it could be a game-changer for everything from quantum computing and medical imaging to energy and transportation. But there are a lot of red flags. If LK-99 is the real ...

If rumor has wings, extraordinary scientific claims have a jet engine. Within hours of appearing on the preprint server arXiv.org, two papers by a team of scientists in South Korea generated enormous ...

Last week, a group of South Korean physicists made a startling claim. In two papers uploaded to the arXiv preprint server, they say they have created a material that “opens a new era for humankind”.

The news doesn’t go long without some kind of superconductor announcement these days. Unfortunately, these come in several categories: materials that require warmer temperatures than previous ...

Superconductors make highly efficient electronics, but the ultralow temperatures and ultrahigh pressures required to make them work are costly and difficult to implement. Room-temperature ...
