Viral New Superconductivity Claims Leave Many Scientists Skeptical

Superconductors that work under real-world conditions—without requiring freezing temperatures or sky-high pressures—could lead to revolutionary applications. These materials might enable power grids that carry electricity perfectly without ever losing energy, levitating trains, next-generation fusion reactors and portable MRI scanners, among other technology. A new pair of papers dangles the possibility that a material called LK-99 could be superconducting in room conditions. But they have not yet been peer reviewed, and many scientists remain skeptical. And this field of research has a long history of apparent breakthroughs that, upon further scrutiny, fail to pan out.

QUOTE OF THE DAY

"This cute canine behavior is familiar to dog owners, but no one really knows why human's best friend does it--and scientists have published just one study focusing on possible reasons for head tilting in dogs. That research suggests the animals might cock their furry noggins when processing familiar words."
