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

Attorney General Bill Barr will not recuse himself from overseeing special counsel Robert Mueller's investigation into Russian interference in the 2016 election, the Justice Department announced Monday."Following General Barr's confirmation, senior career ethics officials advised that General Barr should not recuse himself from the Special Counsel's investigation. Consistent with that advice, General Barr has decided not to recuse," according to Justice Department spokesperson Kerri Kupec.Prior to his confirmation, Democrats had raised concerns about a 19-page memo Barr authored in June 2018 detailing why he believed President Donald Trump's firing of FBI Director James Comey should not constitute obstruction of justice. Barr vowed to consult with ethics officials but did not make any pledge to recuse himself from the Russia probe. 855

BAKERSFIELD, Cali. — A California native is learning that her family tree is a lot larger than she had ever thought after growing up as an only child. Forty-one years late, she found that she has 22 half brothers and sisters that she never knew about.Jennifer Slayton said that she took a 23andme DNA test four months ago and was contacted by one of her half brothers in January. She was then introduced to her 21 other half-siblings shortly after.Slayton said there could be more siblings out there, but she's grateful to have the ones she has.She said that she first learned she was donor conceived at the age of 17. Slayton said that her father was diagnosed with a very serious form of dementia that was hereditary and this caused her to be worried that she would inherit it. That's when her mother informed her that he was not biologically her father.She said that technology limitations at the time kept her from finding her father, but in 2018 her husband wanted to try out the DNA kit for fun.After the results came back, one of her half brothers, Evan, contacted her. She asked how many of them there were and he told Slayton that she was number 21. "They're amazing, like I went and met them for the first time and I was really nervous and I walked in and it was like meeting versions of myself," Slayton said. "Like all of these people have so much in common with me and they are nice, obviously, and they are friendly and we have a lot of the same interests and the same mannerisms, we all talk with our hands a lot."Slayton has since started making new memories with her half siblings and has met her donor. She said that she has several family get-togethers planned and they are all waiting to see if more matches pop up. 1748
