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

Brian Thomas just bought a new washing machine after spending time looking for a good deal."I found it a little stressful," he said. But he found a great deal.That stress he was enduring is happening to other consumers as tariffs have already led to price increases. It’s sticker shock. "It's increased, absolutely — you see 0-0 increase at least in what I looked at,” Thomas said.Appliances in particular have price increases from tariffs. Mexico exported billion worth of appliances just to the United States last year. At that time, the Trump administration hit the country with a 25 percent tariff on all imported goods.While the two countries play economic hardball, it’s the consumer who ends up paying more for everyday items coming from overseas.Metro University Associate Economics Professor Alexandre Padilla said there is debate on how tariffs will impact all. "The people that mostly are hurt or harmed by those tariffs are actually on the lower side of income,” Padilla said.People in favor of the tariffs say they keep jobs in the U.S."Should we penalize 10 million people to save a hundred thousand jobs? That's the question,” Padilla said.While Mexico tariffs are currently not in place, China's are. In May, tariffs increased on 0 billion worth of Chinese goods. 1305

As Hurricane Dorian ravaged Freeport, the main city on Grand Bahama, fisherman Howard Armstrong had to watch helplessly as his wife died in the rising flood that claimed their home.The water rose quickly, he told CNN, and soon it was up to their necks."We were doing all right until the water kept coming up, and all the appliances were going around the house, like the washer machine," said Armstrong, who is a crab fisherman.His wife, Lynn, was standing on the kitchen cabinets, the only place where "your head would touch the roof," he said. Only their heads were above the water.After hours of waiting in the flooded house for rescue, Armstrong's wife succumbed to hypothermia and slipped under the water."And then I kept with her, and she just drowned on me," he said, breaking down.When the storm finally released its devastating hold on the Bahamas on Tuesday, seven people were known to have died -- all on the Abaco islands, east of Grand Bahama -- and officials fear the death toll will rise sharply as more accounts like Armstrong's come to light."She was gone so quickly," Armstrong said as he waited for his wife's body to be recovered.Armstrong said he then "took a chance" and swam outside the house to his boat, which was moored nearby."I saw my boat was still there, and I swam," he said.Armstrong said he'd lived in Freeport for 58 years and had "battled many a hurricane," but had never seen flooding like this."Everything I own is gone," Armstrong said. "Every single thing." 1507
