[Q]: (CNN) Though many individuals likely contributed to the President's decision to fire FBI Director James Comey, one notable one may have been Roger Stone, a 64-year-old close friend of Donald Trump and central figure in the FBI investigation into Trump campaign ties to Russia. In the middle of the Watergate scandal, Stone, who engaged in dirty tricks during Richard Nixon's 1972 campaign, was discovered to have hired a Republican operative to infiltrate the George McGovern campaign and was subsequently fired from his job. After the President's resignation, Stone remained an ardent Nixon apologist and loyalist. He even had the man's face tattooed on his back and devoted his life to ruthless, anything-goes politics (or political consulting, as you may know it). Stone's motto was and continues to be: "Admit nothing, deny everything, launch counterattack." And anyone who has watched Trump closely over the years would think it was his personal slogan, too.Michael D'Antonio: Roger Stone has undoubtedly influenced President Trump's decision to fire James ComeyAs an old friend and political adviser, Stone has taught Trump be ruthless -- particularly when protecting himself from attackTherefore Comey, who was leading the investigation into Trump campaign ties to Russia, had to be taken out, writes D'Antonio

[Q]: Researchers have discovered four extinct underwater volcanoes thousands of feet below the water off the coast of Sydney The calderas are believed to have formed 50 million years ago when supercontinent Gondwana was splitting up into the regions we now know as Australia and New Zealand. And this quartet of 'hotheads' may offer geologists clues about how exactly this tectonic movement took place. The volcanoes were discovered 125 miles (200km) off the southwestern Australian coast using the Investigator ocean explorer from the Commonwealth Scientific and Industrial Research Organisation (CSIRO). Scientists from the University of New South Wales Australia were searching for nursery grounds for larval lobsters when the sonar images spotted the volcanoes 16,100 feet (4,900 metres) underwater.Four volcanoes found in a cluster 125 miles (200km) off coast of SydneyResearchers found the ancient underwater formation by accidentCluster is 12 miles (20km) long, 4 miles (6km wide) and rises 230ft (700m)Experts believe they tell 'part of the story' of how Australia and New Zealand separated between 40 and 80 million years ago

[Q]: Scotland rugby fans are not, as a rule, the kind of folk who fling Mars bars at directors’ boxes or strike up furious chants demanding a change of leadership. It takes something hugely infuriating to prompt them out of their beery reverie and happily soused sense of match-day bonhomie, a state of mind where every stranger is regarded as just a friend they haven’t met, and where the pain of loss is tempered by the knowledge that their new best pals are enjoying victory. The actions of one poor demented soul at Murrayfield on Saturday evening offered a brief and revelatory glimpse, then, of how deeply the national mood has darkened at the end of an emotionally exhausting Six Nations Championship, a campaign that moved from promising to properly poor without bothering to shift through the gears.Scotland were thrashed 40-10 by Six Nations winners Ireland on SaturdayVern Cotter's side lost all their Six Nations games and finished lastScotland's World Cup campaign starts in September against Japan
