writes that a study suggests that tuberculosis first appeared in the New World less than 6,000 years ago and it was brought here by seals
. After a remarkable analysis of bacterial DNA from 1,000-year-old mummies, scientists have proposed a new hypothesis for how tuberculosis arose and spread around the world. The disease originated less than 6,000 years ago in Africa, they say, and took a surprising route to reach the New World: it was carried across the Atlantic by seals. The new study, published Wednesday in the journal Nature, has already provoked strong reactions from other scientists. "This is a landmark paper that challenges our previous ideas about the origins of tuberculosis," said Terry Brown, a professor of biomolecular archaeology at the University of Manchester. "At the moment, I'm still in the astonished stage over this."Read Replies (0)

writes We're often told that having a kill switch in our mobile devices — mostly our smartphones — is a good thing. At a basic level, that's hard to disagree with. If every mobile device had a built-in kill switch, theft would go down — who would waste their time over a device that probably won't work for very long? Here's where the problem lays: It's law enforcement that's pushing so hard for these kill switches. We first learned about this last summer, and this past May, California passed a law that requires smartphone vendors to implement the feature. In practice, if a smartphone has been stolen, or has been somehow compromised, its user or manufacturer would be able to remotely kill off its usability, something that would be reversed once the phone gets back into its rightful owner's hands. However, such functionality should be limited to the device's owner, and no one else. If the owner can disable a phone with nothing but access to a computer or another mobile device, so can Google, Samsung, Microsoft, Nokia or Apple. If the designers of a phone's operating system can brick a phone, guess who else can do the same? Everybody from the NSA to your friendly neighborhood police force, that's who. At most, all they'll need is a convincing argument that they're acting in the interest of "public safety."Read Replies (0)

writes: Scientists have found that, despite a complete ban since 2007, ozone-depleting chemicals are still being pumped into the atmosphere from some unknown source. "Carbon tetrachloride (CCl4), which was once used in applications such as dry cleaning and as a fire-extinguishing agent, was regulated in 1987 under the Montreal Protocol along with other chlorofluorocarbons that destroy ozone and contribute to the ozone hole over Antarctica. Parties to the Montreal Protocol reported zero new CCl4 emissions between 2007-2012. However, the new research shows worldwide emissions of CCl4 average 39 kilotons (about 43,000 U.S. tons) per year, approximately 30 percent of peak emissions prior to the international treaty going into effect. "We are not supposed to be seeing this at all," said Qing Liang, an atmospheric scientist at NASA's Goddard Space Flight Center in Greenbelt, Maryland, and lead author of the study published online in the Aug. 18 issue of Geophysical Research Letters, a journal of the American Geophysical Union. "It is now apparent there are either unidentified industrial leakages, large emissions from contaminated sites, or unknown CCl4 sources."Read Replies (0)

An anonymous reader writes eBooks are great and wonderful, but as The Guardian reports, they might not be as good for readers as paper books. Results from a new study show that test subjects who read a story on a Kindle had trouble recalling the proper order of the plot events. Out of 50 test subjects, half read a 28-page story on the Kindle, while half read the same story on paper. The Kindle group scored about the same on comprehension as the control group, but when they were asked to put the plot points in the proper order, the Kindle group was about twice as likely to get it wrong.
So, is this bad news for ebooks? Have we reached the limits of their usefulness? Not necessarily. While there is evidence that enhanced ebooks don't enhance education, an older study from 2012 showed that students who study with an e-textbook on an ebook reader actually scored as well or higher on tests than a control group who did not. While that doesn't prove the newer research wrong, it does suggest that further study is required.
What has your experience been with both recall and enjoyment when reading ebooks?Read Replies (0)

writes: Eeva Haaramo reports on Helsinki's ambitious plan to transform city transportation. From on-demand buses to city bikes to Kutsuplus mini-transport vans, the Finnish capital is trying to change the whole concept of getting around in a city. "Under the plan, all these services will be accessed through a single online platform. People will be able to buy their transport in service packages that work like mobile phone tariffs: either as a complete monthly deal or pay as you go options based on individual usage. Any number of companies can use the platform to offer transport packages, and if users find their travel needs change, they'll be able to switch packages or moved to a rival with a better deal."Read Replies (0)

Via TorrentFreak comes news that Google is now being asked to remove one million links per day
(or an average of one takedown notice every 8ms). In 2008, they received one takedown request approximately every six days. From the article: The massive surge in removal requests is not without controversy. It’s been reported that some notices reference pages that contain no copyrighted material, due to mistakes or abuse, but are deleted nonetheless. Google has a pretty good track record of catching these errors, but since manual review of all links is unachievable, some URLs are removed in error. ... The issue has also piqued the interest of U.S. lawmakers. Earlier this year the House Judiciary Subcommittee had a hearing on the DMCA takedown issue, and both copyright holders, Internet service providers, and other parties are examining what they can do to optimize the process.
In the meantime, the number of removal requests is expected to rise and rise, with 10 million links per week being the next milestone. Read Replies (0)

Digia has announced that existing Qt modules will now be covered under the LGPLv3
in addition to the LGPLv2.1, GPLv3, and the enterprise (proprietary) license. New modules will be dropping LGPLv2.1 and GPLv3+ and be released under the LGPLv3 and GPLv2+ instead. This should be a good move: new Qt modules will be Apache license compatible, LGPLv3 code can trivially be converted to GPLv3, and Digia is even releasing a few modules it intended to make proprietary as Free Software. The KDE Free Qt Foundation is on board
. The move was made because of device vendors exploiting a loophole in the GPLv2/LGPLv2.1
that denied users the right to modify Qt or write their own applications. Digia has some self-interest as well, since those vendors were exploiting the tivoization loophole to avoid buying enterprise licenses. From the announcement:We also consider locked-down consumer devices using the LGPL’ed version of Qt to be harmful for the Qt ecosystem. ... Because of this, we are now adding LGPL v3 as a licensing option to Qt 5.4 in addition to LGPL v2.1. All modules that are part of Qt 5.3 are currently released under LGPL v2.1, GPL v3 and the commercial license. Starting with Qt 5.4, they will be released under LGPL v2.1, LGPL v3 and the commercial license. ... In Qt 5.4, the new Qt WebEngine module will be released under LGPL v3 in the open source version and under a LGPLv2.1/commercial combination for Qt Enterprise customers. ...
