    The LK-99 ‘superconductor’ went viral — here’s what the experts think

    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.

    It’s “NOT a superconductor,” says the University of Maryland’s Condensed Matter Theory Center (CMTC).

    Early results are in from attempts to recreate LK-99 and see if it truly is the room-temperature superconductor of people’s dreams.

    CMTC cites discouraging results from the CSIR-National Physical Laboratory in India and the International Center for Quantum Materials in China. We’ll hear from more labs soon, but at this point, it’s looking like LK-99 was too good to be true.

    The hottest month on the planet was extra brutal in Phoenix.

    Temperatures hit at least 110 degrees Fahrenheit in Phoenix for 31 days in a row. The record-smashing heat has crowded hospitals with patients struck with heat illness or who burned themselves on scorching hot pavement. July is expected to go down as the planet’s hottest month on record, and North America’s heatwaves this month would have been virtually impossible without climate change.
