After having already tried to explain itself with metaphor, Carrier IQ is now taking its floundering PR campaign back to basics, with an ostensibly thorough primer on its practices and a slightly less convoluted defense of its privacy standards. This morning, the controversial analytics firm released a lengthy, 19-page document that attempts to explain “what Carrier IQ does and does not do.” In the report, titled “Understanding Carrier IQ Technology,” the company explains the benefit it offers to its clientele of network operators, many of whom rely upon Carrier IQ’s diagnostic data to make sure their infrastructure is up to snuff. It also provides a breakdown of how it collects data, as well as a defense against Trevor Eckhart’s findings, though, as you’ll see, these arguments likely won’t put this saga to bed anytime soon.

NASA has of course long been monitoring the affects of spaceflight on astronauts’ health, but a recent study sponsored by the space agency is now shedding some new light on one potentially significant problem: their eyesight. While the study only involved seven astronauts, all reported that they suffered some degree of blurry vision while on the space station for more than six months, and some reported that the effects persisted for months after they returned to Earth. The study also found specific abnormalities in all of the astronauts affected, including changes in tissue, fluids, nerves and other structures in the back of the eye. Those problems are all relatively minor and correctable, but researchers are now also taking the findings and working on ways to determine who might be most resistant to any such changes, which could be critical on something as long as a three-year mission to Mars. Additional details of the study are in the press release after the break, and the full report is published in the latest issue of Ophthalmology.
