As coronavirus has quickly spread across the world, so too has the use of face masks. During a pandemic, putting on a mask may be the first thing you think to do in order to protect yourself. But public health researchers have no concrete evidence yet that masks alone significantly reduce a healthy person’s chances of getting sick.And if healthy people buy and use up large quantities of masks, there won't be enough for sick people, who are mostly likely to spread the disease, or for frontline health workers, who more frequently come into contact with the COVID-19 virus as they care for the severely ill. Experts estimate health care systems in the US will need 3.5 billion masks -- quite a bit more than than the national stockpile of about 42 million. But if every person in the U.S. were to wear one mask each day, we'd need a supply nearing 10 billion for just one month. "The most important use of masks is for our health care workers," Dr. Tom Frieden, the president and CEO of Resolve to Save Lives and former head of the Centers for Disease Control and Prevention, tells Newsy. "That will protect them, so they're there for us. And it will protect other patients as well, preventing them from getting infected."The CDC only recommends that people who are sick and their caregivers wear masks. When masks are unavailable, a scarf or bandana can be used. But more importantly, Frieden urges sick people to just stay home. "If you're sick, don't go out. Don't expose others. Even if you're only mildly sick, your illness may kill somebody else." 1568

As the nation reeled Sunday morning from news of a second mass shooting in the span of 13 hours, Democratic lawmakers began demanding that Senate Majority Leader Mitch McConnell take action this week on long-stalled gun control legislation they argue could help prevent the next large-scale tragedy."I hope that Sen. McConnell would bring the Senate back tomorrow and pass the background check bill and send it to the President. The President must sign it. Period," Ohio Democratic Sen. Sherrod Brown told CNN's Jake Tapper on "State of the Union."Early Sunday morning, a shooter in Dayton, Ohio, opened fire in the city's Oregon District, a popular downtown area, leaving nine dead. The shooter, a 24-year-old male, was shot and killed by responding officers. Thirteen hours earlier, a gunman opened fire at a shopping center in El Paso, Texas, killing at least 20 people. A 21-year-old white supremacist is in custody in the Texas domestic terrorism case.Congress has long struggled to pass gun control legislation, even in the wake of mass shootings, and Brown's call Sunday adds to a growing chorus of Democratic and progressive lawmakers who have demanded action on gun reform in the aftermath of a tragedy.Brown told Tapper that in addition to sadness, he feels "anger that Congress still doesn't do its job," adding: "The House of Representatives has passed background check legislation, the Senate could meet tomorrow."Reached Sunday, McConnell's office didn't comment on Brown's call for the Senate leader to take action this week on the legislation.McConnell in a tweet Saturday did say "the entire nation is horrified by today's senseless violence in El Paso," following the Texas shooting, adding: "Elaine's and my prayers go out to the victims of this terrible violence, their families and friends, and the brave first responders who charged into harm's way."Demands for congressional action growA number of lawmakers have joined Brown's call for McConnell to act on gun control legislation, including Ohio Democratic Rep. Tim Ryan, who told Fox News on Sunday that "this is ridiculous.""Mitch McConnell and (Senate Minority Leader) Chuck Schumer and (House Speaker) Nancy Pelosi: Let's get back to work in Washington, do the background check bill that we passed out of the House -- we've got to ban these assault weapons," Ryan, a 2020 Democratic presidential candidate, said.Democratic leadership responded by urging McConnell to act.In a statement, Pelosi said, "The Republican Senate must stop their outrageous obstruction and join the House to put an end to the horror and bloodshed that gun violence inflicts every day in America. Enough is enough." And Schumer tweeted the majority leader "must call the Senate back for an emergency session to put the House-passed universal background checks legislation on the Senate floor for debate and a vote immediately."Democratic Sens. Bernie Sanders of Vermont and Kamala Harris of California also weighed in on the matter.Sanders backed the call for McConnell to "bring the Senate back into session immediately to pass HR 8, the gun safety bill that has already passed the House.""That's a first step to addressing our serious gun violence epidemic," Sanders said in a tweet.Harris told Tapper that it's "ridiculous" that Congress doesn't have the "courage to say, 'Hey, fine if y'all want to go hunting, but we need reasonable gun safety laws in our country, including universal background checks, including a renewal of the assault weapons ban.'"Sen. Elizabeth Warren said in a 3555

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
