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

As nearly 450 Pier 1 locations are set to close in the coming year, the company announced it is filing for Chapter 11 bankruptcy. Of the 450 locations set to close, 400 of them have either recently closed or started liquidating stock. In addition to the store closings, the company will shutter two distribution centers. The moves come during a rough time for brick and mortar retailers, as malls and shopping centers throughout the United States become more barren. Pier 1 said it is also in the process of securing a buyer for the company over the next six weeks. “In recent months, we have taken significant steps forward in our business transformation and cost-reduction initiatives," CEO Robert Riesbeck said. "We have worked to establish an appropriately sized and profitable store footprint, operating structure and merchandise assortment that will enable Pier 1 to better serve our customers across store and online channels. "Today’s actions are intended to provide Pier 1 with additional time and financial flexibility as we now work to unlock additional value for our stakeholders through a sale of the Company. We are moving ahead in this process with the support of our lenders and are pleased with the initial interest as we engage in discussions with potential buyers.” 1296
