            >Musk opens underground tunnel
            Elon Musk unveiled his underground transportation tunnel on Tuesday, allowing reporters and invited guests to take some of the first rides in the revolutionary albeit bumpy subterranean tube - the tech entrepreneur's answer to what he calls "soul-destroying traffic". Guests boarded Musk's Tesla Model S and rode along the tunnel. The demo rides were considerably slower - 64 km per hour - than what Musk says the future system will run at: 240 km per hour. The car jostled significantly during the ride, which was bumpy enough to give one reporter motion sickness. Musk touted the newly finished 1.83 km tunnel segment as a breakthrough in low-cost, fast-digging technology being pioneered by his nascent tunneling firm, the Boring Company.
            埃隆?马斯克18日揭开了他打造的地下交通隧道的神秘面纱,允许记者和受邀嘉宾成为这条尽管颠簸但颇具革命性的地下管道的首批乘客。这位科技企业家希望借助这种地下隧道来治愈他所说的"破坏灵魂的交通"。客人们登上一辆特斯拉Model S,沿着隧道兜风。尽管马斯克表示,未来这一轨道系统的时速将达到240公里,但试乘时汽车的时速要慢得多,仅为64公里。汽车在行驶过程中颠簸不已,导致一名试乘的记者开始晕车。马斯克称赞这段新建的长1.83公里的隧道是他初创的隧道挖掘公司"无聊公司"在低成本、快速挖掘技术上的突破。

            >Parrot uses Alexa to order
            A mischievous parrot who was booted from an animal sanctuary for his foul mouth has found a friend in Amazon's Alexa device. Rocco, an African gray, was caught using the voice assistant to play his favorite music, tell jokes and even order snacks. Thankfully the device's parental lock system prevented the clever boy from actually purchasing any items - which included strawberries, ice cream and even a kettle. Owner Marion Wischnewski said she took the parrot in after he was removed from a sanctuary operated by the UK's National Animal Welfare Trust for swearing too much. Rocco, who was taught to curse by a previous owner, is evidently loving his new home, interacting with Alexa up to 40 times a day and mastering countless household sounds. He can make various mobile ringtones, the beep of the microwave and the squeaking of the refrigerator door, as well as the sound of an ice cream van or a reversing truck, according to Wischnewski.

            >Alien life might be purple
            The conclusion of a new research paper suggests that the first life on Earth might have had a lavender hue. In the International Journal of Astrobiology, microbiologist Shiladitya DasSarma of the University of Maryland School of Medicine and postdoctoral researcher Edward Schwieterman at the University of California, Riverside, argue that before green plants started harnessing the power of the sun for energy, tiny purple organisms figured out a way to do the same. There is even some evidence that modern purple-pigmented salt-loving organisms called halophiles might be related to some of the earliest life on Earth, which thrived around methane vents in the ocean. Alien life could be thriving in the same way, the researchers said.

            >2.9M to sit postgrad exam
            A total of 2.9 million Chinese will sit the national entrance exam for postgraduate studies from Dec 22 to 24, the Ministry of Education said Wednesday. The ministry has released numbers of telephone hotlines on its website to receive public tip-offs regarding cheating on the postgraduate entrance exam and other violations. A few suspects have been seized for exam-related fraud amid a nationwide crackdown ahead of the entrance exam, said the ministry.
