【#纽约警局机器狗警员上岗# 赛博朋克时代真的来了？】最近，纽约警局新上岗的“机器狗警员”引起了人们的热议。由波士顿动力公司研制的这款“机器狗”可谓多才多艺，会跳绳、会巡街，还能进行危险作业和数据收集，颇为引人注目。譬如在警方解救人质时，警员会远程操控机器狗，在行动前评估危险的等级和人质所在地点和具体情况。机器狗的电池能持续运行90分钟，移动速度接近5公里/小时，内置摄像头和照明灯，还具备夜视能力。纽约警方正在对“机器狗”和其它型号的机器人进行测试和评估。除纽约警方外，马塞诸塞州警方和火奴鲁鲁警方也各上岗了一名机器狗警员。不过，“机器狗”当警察，有些人担心，让机器人替代警员执勤，是否会增加信息和隐私泄露的危险。对此，你怎么看？The New York Police Department (NYPD) has been utilizing a 70-pound robot "dog" to assess dangerous and hostage situations before moving in. The robot with a 90-minute battery life and a walk-speed of three miles per hour, is maneuvered remotely by police operators. It has cameras and lights built in, and also night vision. "This model of robot is being tested to evaluate its capabilities against other models in use by our emergency service unit and bomb squad," an NYPD News statement said. The NYPD is one of three departments to own a mechanical dog, built by Boston Dynamics. Other two are the Massachusetts State Police and the Honolulu Police Department.
How many servings of fruits and veggies should you be getting each day to live a longer life? A new study published in Circulation, the journal of the American Heart Association, aims to provide an answer.

Diets that are rich in fruits and vegetables "help reduce [the] risk for numerous chronic health conditions that are leading causes of death, including cardiovascular disease and cancer," per a news release on the findings.
