    • The machine-learning algorithm works by analyzing the online behavior of visitors to the Northwell Health website and comparing that data to future COVID-19 hospitalizations.
    • The tool, which uses anonymized data, has so far predicted hospitalizations with an accuracy rate of 80 percent.
    • Machine-learning tools are helping health-care professionals worldwide better constrain and treat COVID-19.

    Michio Kaku: 3 mind-blowing predictions about the future

    What lies in store for humanity? Theoretical physicist Michio Kaku explains how different life will be for your ancestors—and maybe your future self, if the timing works out.

    • Carl Sagan believed humanity needed to become a multi-planet species as an insurance policy against the next huge catastrophe on Earth. Now, Elon Musk is working to see that mission through, starting with a colony of a million humans on Mars. Where will our species go next?
    • Theoretical physicist Michio Kaku looks decades into the future and makes three bold predictions about human space travel, the potential of 'brain net', and our coming victory over cancer.
    • "[I]n the future, the word 'tumor' will disappear from the English language," says Kaku. "We will have years of warning that there is a colony of cancer cells growing in our body. And our descendants will wonder: How could we fear cancer so much?"

    Designer uses AI to bring 54 Roman emperors to life

    It's hard to stop looking back and forth between these faces and the busts they came from.

    • A quarantine project gone wild produces the possibly realistic faces of ancient Roman rulers.
    • A designer worked with a machine learning app to produce the images.
    • It's impossible to know if they're accurate, but they sure look plausible.
