World No 1 Novak Djokovic barely broke sweat as he dispatched Brazil's Joao Souza for the loss of just three games in the US Open first round. Djokovic is gunning for his third grand slam title of the year after triumphs at the Australian Open and Wimbledon, and the Serb put on a dominant opening display in New York to win 6-1, 6-1, 6-1. The victory took just one hour and 11 minutes to complete, with Djokovic now up against either Canada's Vasek Pospisil or Austrian Andreas Haider-Maurer in round two. Djokovic arrived in Flushing Meadows with some question marks hanging over his form following defeats in consecutive weeks to Andy Murray in Montreal and Roger Federer in Cincinnati.World No 1 Novak Djokovic recorded a 6-1, 6-1, 6-1 victory in New YorkAustralian Open and Wimbledon champion chasing third grand slam title

(CNN) For the first time, eight planets have been found orbiting a distant star, Kepler-90, 2,545 light-years from Earth in the Draco constellation, NASA announced Thursday. It is the first star known to support as many planets as are orbiting our own sun, and researchers believe that this is the first of many to come. Researchers had known that seven planets were orbiting the star. But Google Artificial Intelligence -- which enables computers to "learn" -- looked at archival data obtained by NASA's planet-hunting Kepler telescope and uncovered the eighth planet. With the idea of eventually differentiating among exoplanets, Christopher Shallue, senior software engineer at Google AI in California, and Andrew Vanderburg, astronomer and NASA Sagan postdoctoral fellow at the University of Texas, Austin, trained a computer how to differentiate between images of cats and dogs.For the first time, eight planets have been found orbiting Kepler-90It is tied with our solar system for a star hosting the most known planets

(CNN) President Donald Trump, though often acting as a champion of the military, has at times politicized the sacrifice of those who paid a terrible price in the nation's wars in a way that few of his predecessors would have countenanced. He clearly reveres America's fighting men and women. He often boasts about their prowess, has surrounded himself with hard charging generals and has vowed to reinvent veterans' health care. But he's also been happy to use the military for his own political ends when it suits him. The latest episode -- in which Trump falsely claimed Barack Obama didn't call the families of dead soldiers -- is revealing because it shows how Trump lashes out whenever he believes his conduct or character is under attack. It's another case of him citing information that is either incorrect of unverified when he is on the defensive, a trait that often leads him into deeper political trouble.Controversy over Obama calls not the first time Trump has politicized sacrificePresident facing questions over ISIS ambush that killed four soldiers in Niger 
 Questions:Such comments, and his continued propensity for drawing the military into his political spats are only fueling complaints by _'s rivals that he has not fully understood the grave responsibilities of serving as commander in chief.
