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

At a White House briefing on Wednesday, Vice President Mike Pence said that the government will have 1.5 million coronavirus tests ready to distribute this week after bipartisan criticism was levied on the government's ability to distribute tests. Pence added that tests are available in all 50 states, giving doctors the ability to better determine whether patients have been sickened with coronavirus. These tests will go to hospitals and labs at state universities. The eventual goal is to make the tests accessible more broadly. "Our objective is to make tests available broadly to the American public," Pence said. "We want to make sure the American people can go to their doctor, can go to the local MedCheck or CVS, and obtain access to coronavirus (tests)."On Tuesday, members of the Senate Health, Education, Labor and Pensions committee expressed frustration with the distribution of tests. "I'm sure across the nation are really scared," Sen. Patty Murray said at Tuesday's hearing. "I'm hearing from people who are sick who want to get tested, are not being told where to go. I'm hearing that even when people do get tested and it's very few so far, the results are taking way longer to get back to them. "The administration has had months to prepare for this and it is unacceptable that people in my state and nationwide can't even get an answer as to whether or not they are infected."The announcement comes as the death toll nationwide is up to 11 from coronavirus. It also comes as United Airlines announced that it is cutting back the number of domestic and international flights. Administration officials said that elderly and those with pre-existing conditions should reconsider elective travel. Pence and other members of the coronavirus task force said for the general population, the risk posed by coronavirus is low. 1852

As the United States heads toward another presidential election in 2020, social media plays an even bigger role than in previous elections as information is published, shared, tweeted — and "likes" may matter.Does a person's social media following signal how well he or she may do as we get closer to deciding who will appear on the ballot?There are several candidates with big followings: Namely Donald Trump, Bernie Sanders and Elizabeth Warren.
