Science & Technology Last Update on July 31, 2014 07:09 GMT IN THE NEWS: BRITAIN-DRIVERLESS CARS LONDON (AP) -- British officials says driverless cars will be tested on roads in as many as three cities in a trial program to begin in January Officials said Wednesday the tests will last up to three years. Sensors and cameras will guide the cars. The plan will include two types of driverless technology. One places a driver in the car who can take the controls if needed; another calls for a fully autonomous vehicle with no driver present. Transport Minister Claire Perry said driverless cars could transform Britain's road network and improve safety and traffic flow while reducing carbon emissions. The cities to test the system will be chosen in a competition. Other countries including Japan and the United States are already developing driverless technology. IN THE NEWS: GROUP SELFIES GET A NAME NEW YORK (AP) -- What do you call a group selfie? An usie (UHS'-ee) of course! The word has been showing up in written material since at least April 2013, according to Ben Zimmer, executive producer of Vocabulary.com and language columnist for The Wall Street Journal. A Business Insider story from January noted that the outstretched arm of the photo-taker in usies is a "signature" of the image, because the shooter has to get the camera far enough away to get the group in the frame. The Times of India in March said Pope Francis' group selfie with visitors at the Vatican last year "could possibly be the first chronicled celebrity usie." And a PopStopTV.com report from June was headlined: "Selfies Are Dead, Usie is the Latest Trend!"
