Bernie Sanders has scored a resounding victory in Nevada’s presidential caucuses. His win on Saturday cements his status as the Democrats' national front-runner, though it's also escalating tensions over whether he’s too liberal to defeat President Donald Trump. The 78-year-old Vermont senator successfully rallied his loyal base and tapped into support from Nevada’s large Latino community as the Democratic contest moved for the first time into a state with a significant minority population. Sen. Sanders is celebrating his Nevada caucus victory hundreds of miles away in Texas.The Vermont senator took the stage before thousands of cheering supporters inside the Cowboys Dance Hall in San Antonio on Saturday night and declared, “We’re going to win this election.” The country’s second largest state votes on “Super Tuesday” on March 3, after next week’s South Carolina primary, but Sanders wasted little time declaring, “We are going to win here in Texas.”He added: “We are going to win across the country because the American people are sick and tired of a president who lies all of the time.”Sanders then modified the standard campaign speech he gives multiple times a day to touch more heavily on immigration for an audience about 150 miles from the U.S.-Mexico border. He noted that his father immigrated to the U.S. from Poland "without a nickel in his pocket" and added, "I know something about the immigrant experience. Together we are going to end the demonization” of immigrants.Amy Klobuchar is telling supporters her presidential campaign has “exceeded expectations” and she plans to carry on, even as she trailed far behind several rivals in Saturday’s Nevada caucuses.The Minnesota senator returned to her home state Saturday following a morning event in Las Vegas. Speaking to volunteers Klobuchar said that "a lot of people didn’t even think I would still be standing at this point."Klobuchar finished in fifth place in the kickoff Iowa caucuses before a strong debate performance helped lift her to third place in New Hampshire. She will campaign Sunday in Fargo, North Dakota, before holding events in Arkansas and Oklahoma, both states that will vote in the March 3 “Super Tuesday” contests. On Monday she will be in South Carolina, which holds its primary Saturday and where she will participate in a Tuesday debate.Meanwhile, Joe Biden is declaring himself back into the race for the presidency after early results in Nevada showed the former vice president in second place. Biden told supporters Saturday that “we're alive and we're coming back and we're gonna win.” Biden thanked unions for their support, citing labor groups that have endorsed him including firefighters, ironworkers and electrical workers.He took a shot at the race's frontrunner, self-declared democratic socialist Bernie Sanders, and former New York Mayor Mike Bloomberg, who isn't competing in the first four states but has spent hundreds of millions of dollars of his own fortune hoping to pick up delegates starting on Super Tuesday."I ain't a socialist. I ain't a plutocrat," Biden said. "I'm a Democrat. And I'm proud of it."Biden said the Russians will continue to support President Donald Trump and Sanders, whose campaign acknowledged Friday that he was briefed last month by U.S. officials about Russian efforts to boost his candidacy."Let's give Trump exactly what he doesn’t want," Biden told his supporters. “Let's give him you and Joe Biden as the nominee.” 3481

As the country continues to rebound, we are hearing a different strategy on kids going back to in-person schooling.“We highlight the need for in the reopening to focus on the children who are most at risk and prioritize those with the greatest needs,” said Christopher Morphew, dean of the Johns Hopkins University School of Education. Education and public health experts at Johns Hopkins outlined a six-point plan based on safety, health and academic needs. They focus first on kids with remote learning barriers, special education students, and those who rely on schools for food support.“We are seeing reports from children who say they aren’t learning as much, that they don’t have access to people to help them, that they don’t feel as comfortable learning,” said Morphew. The experts argue districts with limited resources should start with bringing back the youngest children first because they don't do as well with virtual learning. But they also warn a virtual backup plan is needed should virus cases show up in school.Families who may not feel comfortable going back or have special higher risk circumstances like a grandmother taking care of a young child should also have virtual options.There are other concerns beyond educational needs.“The kids get a lot of social and emotional development. They get relationships with the teacher, which is extremely important for them and their friends, and cutting kids off from that for a critical period of their lives, for an extended period, is really detrimental to them,” said Dr. Josh Sharfstein with the Johns Hopkins Bloomberg School of Public Health.More than 20 million children rely on school breakfast or lunch for food. Surveys indicate one in five mothers report their children younger than 12 years old are going hungry. Another key role schools play – teachers and other officials recognize about one in five cases of possible child abuse. 1922

An explosion has caused a fire at a Russian biological research facility that's one of only two centers in the world known for housing samples of the smallpox virus.The blast occurred Monday during repair work of a sanitary inspection room at the Russian State Centre for Research on Virology and Biotechnology, known as Vector, near the Russian city of Novosibirsk in Siberia, the center 401

As the White House looks for ways to restore normalcy in parts of the U.S., the government's foremost infection disease expert has a sober prognosis. Dr. Anthony Fauci tells CNN the country could see 100,000 to 200,000 deaths from the coronavirus and millions of infections.He says the pandemic is such a “moving target” that it's hard to pin down such a forecast. House Speaker Nancy Pelosi says President Donald Trump refused to acknowledge the severity of the crisis early on. And she says that has cost lives. 525

As computers, tablets and cellphones have become a growing part of our lives, the exposure to blue light emitted from these devices increases. While blue light exposure has been known to cause strain in eyes, Oregon State University researchers studied the effect of blue light exposure on aging. Based on to their findings, exposure to blue light could cause aging to accelerate. For their study, researchers used common fruit flies and exposed them to 12 hours of blue LED light and 12 hours of darkness. To compare, researchers kept a group of flies in total darkness, as well as a group of flies that were exposed to light that had the blue wavelengths filtered out. The researchers said they chose fruit flies because their cellular and developmental mechanisms are similar to humans.The researchers said that flies exposed to blue LED light sustained damage to their retinal cells and brain neurons and had impaired locomotion. Even more stunning, some of the flies, which exhibited some brain damage, were mutants that did not develop eyes."The fact that the light was accelerating aging in the flies was very surprising to us at first,” said Jaga Giebultowicz, a professor of integrative biology at Oregon State. “We’d measured expression of some genes in old flies, and found that stress-response, protective genes were expressed if flies were kept in light. "We hypothesized that light was regulating those genes. Then we started asking, 'what is it in the light that is harmful to them,' and we looked at the spectrum of light. It was very clear cut that although light without blue slightly shortened their lifespan, just blue light alone shortened their lifespan very dramatically.” 1708
