    江苏快三开奖结果The researchers described the new progress as "quantum supremacy." This term describes a point at which a quantum computer can perform a calculation that a traditional computer could never complete within its lifetime.

    The team expressed excitement at the progress made, but said much more research is needed to come up with a fully working 3D-printed human heart that can effectively pump blood.

    Solar roof car

    South Korea's Hyundai Motor Group announced the of its first vehicle with a solar top, or roof, charging system. The new system became available for Hyundai's new Sonata Hybrid model.

    Facial recognition opposition

    San Francisco became the first major U.S. city to ban facial recognition technology by local law enforcement and all other city agencies.

    Internet inventor warns

    The man credited with inventing the World Wide Web called for major changes to make the internet better for humanity. Tim Berners-Lee first proposed the internet system 30 years ago.

    Berners-Lee spoke several times during 2019 about the current state of the internet, now used by about half the world's population.

    In an open letter, Berners-Lee said the web had clearly created great opportunities for humanity to progress and made life easier for millions of people. It also gave groups traditionally not heard a new voice in society. However, he added that the web had also provided new ways for "scammers江苏快三开奖结果" to carry out crimes and "given a voice to those who spread hatred."
