SEOUL, South Korea — North Korean state media say leader Kim Jong Un urged officials to maintain alertness against the coronavirus, warning that complacency risked “unimaginable and irretrievable crisis." Despite the warning, Kim reaffirmed North Korea’s claim to not have had a single case of COVID-19. The country described its anti-virus efforts as a matter of national existence earlier this year. The reports on Thursday's high-level ruling party meeting say Kim stressed the need for vigilance as the virus continues to spread in neighboring countries.Experts say North Korea's lockdown is hurting an economy already battered by U.S.-led sanctions over its nuclear weapons program. 695

Spring is a season of change and typically brings some of the wildest weather across the United States. This weather is spawned from a clash of air masses, as warm and humid air begins to creep north from the Gulf of Mexico while bitter shots of cold air continue to drop in from Canada.This year, spring hasn't seen much of a show. A good portion of the eastern and central US had a cool March, and April has begun similarly. Rather than the bout after bout of severe storms that we frequently see during the transition of seasons, March and April have had wild weather in the form of snow and record low temperatures.Ask any baseball fan across the Midwest and Northeast. Numerous early-season games have been canceled or postponed due to the snow and cold. Even the Chicago Cubs' home opener on Monday -- the last in the league -- was moved to Tuesday thanks to a couple of inches of snow.All of that is beginning to change as warmer air builds over the central US and a vigorous system takes shape and moves east out of the Rockies on Thursday night. This system will form a cocktail of extreme weather, with critical fire danger in the Southern Plains, severe storms in the Mississippi River Valley and heavy snow for the Northern Plains and Upper Midwest. 1269

SpaceX has brought two NASA astronauts home from a historic mission.Robert and Behnken and Douglas Hurley — the first astronauts to travel into orbit aboard a commercially developed spacecraft — returned home in a splashdown mission Sunday, the first such mission in America in 45 years.They've been onboard the International Space Station for two months after launching in the SpaceX Crew Dragon from Kennedy Space Center in Florida.Their spacecraft is nicknamed Endeavour."For the most part, we've had pretty good luck with, with Endeavour," Hurley said. "As far as on-orbit testing is performed, just like it did for launch and rendezvous. So we expect nothing different for the splashdown."The splashdown took place despite the presence of Hurricane Isaias, which did not have a significant effect on the mission. 825
