(AP) — Researchers are concerned about reports from Britain and South Africa of new coronavirus strains that seem to spread more easily. Scientists say it's unclear if that's true. And for now, they don't think the new strains cause more severe COVID-19 illness or pose any concern for vaccines. Viruses naturally evolve as they move through the population. One strain recently detected in England has a lot of changes to the spiky protein that's targeted by current vaccines. The advice to the public remains the same — wear a mask, wash hands often, and keep social distance to avoid catching and spreading the virus. 627

(CNN) -- Cindy McCain, the widow of Sen. John McCain, posted a hateful message she received from a stranger the same day President Donald Trump disparaged her late husband.McCain posted a photo of the private message on Twitter and wrote, "I want to make sure all of you could see how kind and loving a stranger can be. I'm posting her note for her family and friends could see."The message said the sender was "glad" the late Arizona Republican is dead, and called him a "traitorous piece of warmongering s***." The message also attacked her daughter, Meghan McCain, criticizing her appearance and saying she hopes she "chokes to death."More than six months after John McCain's death, Trump revived his years-long feud with the senator over the weekend. Trump said on Tuesday, "I was never a fan of John McCain and I never will be."The President tweeted several attacks on the late senator, focusing on McCain's ties to the controversial Russia dossier and his vote against repealing Obamacare, and said McCain had been "last in his class" at the US Naval Academy.Despite Trump's comments, he gave more than ,000 to the campaign to elect McCain president in 2008, according to the Federal Election Commission's website.Meghan McCain fired back at the President on Monday on ABC's "The View," the show she co-hosts, and said, "Listen, he spends his weekend obsessing over great men because he knows it, and I know it, and all of you know it: He will never be a great man.""My father was his kryptonite in life, he was his kryptonite in death," Meghan McCain said, adding that she thought Trump's life was "pathetic."John McCain died in 2018 after a battle with brain cancer. The President was not invited to his funeral.The senator delivered a speech in 2017 repudiating the President, and warned the United States against turning toward "half-baked, spurious nationalism cooked up by people who would rather find scapegoats than solve problems."When Trump was running for president in 2015, he said John McCain was "not a war hero. He was a war hero because he was captured. I like people who weren't captured."During the final days of the last presidential election, McCain withdrew his support for Trump when the "Access Hollywood" video was made public, showing the 2016 Republican nominee bragging about sexually assaulting women.Their long-running feud escalated when the senator voted no on the "skinny repeal" of the Affordable Care Act in 2017, essentially killing Republican attempts to undo President Barack Obama's signature legislation. 2560

"I am outraged that a group hung an effigy of Governor Beshear today at the Capitol and the House Majority Caucus condemns this act of hatred. The party of Lincoln will not condone this. There is no place in a civil society for it, nor is there any good to be accomplished from it. This weekend we honor those who died defending our right to speak freely. Today's actions are an insult to their sacrifice and the kind of incendiary action that can only cause harm." 473

(CNN) -- Another mountaineer has died after summiting Mount Everest, bringing the death toll for the 2019 climbing season to 11 people.American Christopher John Kulish, 61, died on Monday after reaching the top of Everest on the Nepalese side of the mountain in the morning, Meera Acharya, the Director of Nepal's Tourism Department told CNN.While descending, he was strong and safely reached the South Col (situated at an altitude of around 7,900 meters, or 25,918 feet) late Monday evening before he suddenly passed away, she said.Also on Monday, an Austrian family confirmed the death of one of their relatives. Sixty-four-year-old Ernst Landgraf died on Thursday, hours after fulfilling his dream of scaling Everest, according to his obituary and funeral announcement placed by his family.Landgraf lived for his family, climbing, and died fulfilling his dream, the obituary read in part. He is survived by his wife and children. His memorial service will be Wednesday in Ubelbach, Austria.Mountaineers have suggested difficult weather conditions, a lack of experience and the growing commercialization of expeditions as contributing factors to the backlog.British climber Robin Haynes Fisher was one of those who had warned of the dangers of overcrowding."With a single route to the summit, delays caused by overcrowding could prove fatal so I am hopeful my decision to go for the 25th will mean fewer people. Unless of course everyone else plays the same waiting game," he wrote in a captioned Instagram post on May 19.He died after suffering from what appeared to be altitude sickness at 8,600 meters (28,215 feet), while returning from the summit on Saturday.During the week beginning May 20, crowds of climbers became stuck in a queue to the summit, above the mountain's highest camp at 8,000 meters (26,247 feet). The summit of Mount Everest is 8,848 meters (29,029 feet) high.Most people can only spend a matter of minutes at the summit without extra oxygen supplies, and the area where mountaineers have been delayed is known to many as the "death zone."Mountain guide Adrian Ballinger told CNN many see Everest as the "ultimate challenge" but the problem he has seen is the "lower level of experience of the climbers trying to come here and also of the companies that are trying to offer services on the mountain."He continued, "That lack of experience, both with the commercial operators and the climbers themselves, is causing these images we see where people make bad decisions, get themselves in trouble up high and end up having unnecessary fatalities."Ballinger explained that seasoned climbers call any part of the mountain above 26,000 feet "the death zone," adding that "humans just really aren't meant to exist there.""Even when using bottled oxygen, supplemental oxygen, there's only a very few number of hours that we can actually survive up there before our bodies start to shut down. So that means if you get caught in a traffic jam above 26,000 feet ... the consequences can be really severe," he added.Nepali climbing guide Dhruba Bista fell ill on the mountain and was transported by helicopter to the base camp, where he died Friday.And Irish climber Kevin Hynes, 56, died Friday morning on the Tibetan side of Everest in his tent at 7,000 meters (22,966 feet).Two died Wednesday after descending from the summit: Indian climber Anjali Kulkarni, 55, and American climber Donald Lynn Cash, 55.Kalpana Das, 49, and Nihal Bagwan, 27, both from India, also died on Everest this week. Both died Thursday on their return from the summit.Ravi, a 28-year-old Indian climber who goes by one name, died the previous week on May 17.Last week, a search for Irish climber Seamus Lawless, 39, was called off, after the Trinity College Dublin professor fell while descending from the peak, according to the Press Assocation.Lawless is missing, presumed dead.More than 200 mountaineers have died on the peak since 1922, when the first climbers' deaths on Everest were recorded. The majority of bodies are believed to have remained buried under glaciers or snow. 4083
