The LA Times reports that 60% of astronauts who have completed 6 months aboard the International Space Station reported blurring of eyesight upon return.
A newly discovered eye condition found to erode the vision of some astronauts who have spent months aboard the International Space Station has doctors worried that future explorers could go blind by the end of long missions, such as a multiyear trip to Mars. Although blindness is the worst-case scenario, the threat of blurred vision is enough that NASA has asked scores of researchers to study the issue and has put special eyeglasses on the space station to help those affected.
"We are certainly treating this with a great deal of respect," said Dr. Richard Williams, NASA's chief health and medical officer. "This [eye condition] is comparable to the other risks like bone demineralization [loss] and radiation that we have to consider.... It does have the potential for causing mission impact."

Amazon's been cooking something in a supposed Android-based oven for quite some rumored time. Now, an invite has gone out from the Bezos-backed company for an event on the 28th of this month at 10AM. Will the e-retailer officially announce a pair of 7- and 10-inch Kindle refreshes we've seen so much digital ink spilled over, or is this the heavily-skinned Android tab that TechCrunch got its hands-on earlier this month? We'll be there to let you know what the company's got up its e-reading sleeve.
