Humans must prioritise the colonisation of Mars so the species can be conserved in the event of a third world war, SpaceX and Tesla founder Elon Musk said on Sunday. 'It's important to get a self-sustaining base on Mars because it's far enough away from Earth that [in the event of a war] it's more likely to survive than a moon base," Musk said on stage at SXSW – just days after Donald Trump announced plans to meet the North Korean leader, Kim Jong-un, in an attempt to defuse rising nuclear tension
When FIFA greenlit the use of video assistant referees at the 2018 World Cup, there was one overriding question: how long would it take before the technology shaped an important call? Two days into the group stage, officiators have used VAR to call for a key penalty after Australia's John Risdon appeared to have fouled France's Antoine Griezmann with a sliding tackle, disrupting a charge toward a possible goal. Griezmann promptly scored on the subsequent penalty kick, giving France the lead. Tech played a crucial role later in the match, too. Goal-line systems once again helped France after a Paul Pogba shot bounced vertically off Australia's crossbar.
