schwit1 writes: You’ve heard of the Paleo diet, but the next big thing in health may well be the Paleo sleep schedule. A UCLA researcher studied three hunter-gatherer and hunter-farmer groups — the Hadza in Tanzania, San in Namibia, and Tsimane in Bolivia, “who live roughly the same lifestyle humans did in the Paleolithic, ” as NPR reports — and determined our ancient ancestors may not have slept nearly as much we thought, and may have actually slept less than modern Westerners. “People like to complain that modern life is ruining sleep, but they’re just saying: Kids today!” Jerome Siegel tells the Atlantic . “It’s a perennial complaint but you need data to know if it’s true.” Siegel found that members of the three aforementioned groups sleep between 5.7 hours and 7.1 hours per night. That’s less than is recommended for our health, yet the groups seemed very healthy indeed. (And if you’re feeling insomniac, some earlier Slashdot stories about sleep are also pretty thought-provoking.) Read more of this story at Slashdot.

An anonymous reader writes with an update to the news we discussed in July that a small library in New Hampshire would be used as a Tor exit relay. Shortly after the project went live, the local police department received an email from the Department of Homeland Security. The police then met with city officials and discussed all the ways criminals could make use of the relay. They ultimately decided to suspend the project, pending a vote of the library board of trustees on Sept. 15. DHS spokesman Shawn Neudauer said the agent was simply providing “visibility/situational awareness, ” and did not have any direct contact with the Lebanon police or library. “The use of a Tor browser is not, in [or] of itself, illegal and there are legitimate purposes for its use, ” Neudauer said, “However, the protections that Tor offers can be attractive to criminal enterprises or actors and HSI [Homeland Security Investigations] will continue to pursue those individuals who seek to use the anonymizing technology to further their illicit activity.” …Deputy City Manager Paula Maville said that when she learned about Tor at the meeting with the police and the librarians, she was concerned about the service’s association with criminal activities such as pornography and drug trafficking. “That is a concern from a public relations perspective and we wanted to get those concerns on the table, ” she said.

schwit1 writes A giant welding machine, built for NASA’s multi-billion dollar Space Launch System (SLS), has to be taken apart and rebuilt because the contractor failed to reinforce the floor, as required, prior to construction: “Sweden’s ESAB Welding & Cutting, which has its North American headquarters in Florence, South Carolina, built the the roughly 50-meter tall Vertical Assembly Center as a subcontractor to SLS contractor Boeing at NASA’s Michoud Assembly Facility in New Orleans. ESAB was supposed to reinforce Michoud’s floor before installing the welding tool, but did not, NASA SLS Program Manager Todd May told SpaceNews after an April 15 panel session during the 31st Space Symposium here. As a result, the enormous machine leaned ever so slightly, cocking the rails that guide massive rings used to lift parts of the 8.4-meter-diameter SLS stages The rings wound up 0.06 degrees out of alignment, which may not sound like much, “but when you’re talking about something that’s 217 feet [66.14 meters] tall, that adds up, ” May said. Asked why ESAB did not reinforce the foundation as it was supposed to, May said only it was a result of “a miscommunication between two [Boeing] subcontractors and ESAB.” It is baffling how everyone at NASA, Boeing, and ESAB could have forgotten to do the reinforcing, even though it was specified in the contract. It also suggests that the quality control in the SLS rocket program has some serious problems. Read more of this story at Slashdot. 
Apple’s recently released iOS 8.3 update prevents desktop file explorers like iFunBox, iExplorer, iTools, and others from accessing the app directories on your devices. A few have updated with temporary fixes, but it might take a little while before everything’s working again. Read more… 
Shaved heads have come in and out of fashion over the past few decades, but some people don’t have the option of allowing their locks to grow. Thankfully, for those who do suffer from hair loss, or alopecia, help may be at hand. Somewhat counter-intuitively an effective treatment for baldness may come from plucking a certain number of hairs – in a specific formation – from the scalp. Read more… 
An anonymous reader writes: Republican resistance has ended for the FCC’s plans to regulate the internet as a public utility. FCC commissioners are working out the final details, and they’re expected to approve the plan themselves on Thursday. “The F.C.C. plan would let the agency regulate Internet access as if it is a public good…. In addition, it would ban the intentional slowing of the Internet for companies that refuse to pay broadband providers. The plan would also give the F.C.C. the power to step in if unforeseen impediments are thrown up by the handful of giant companies that run many of the country’s broadband and wireless networks.” Dave Steer of the Mozilla Foundation said, “We’ve been outspent, outlobbied. We were going up against the second-biggest corporate lobby in D.C., and it looks like we’ve won.” Read more of this story at Slashdot.
