Researchers at the Massachusetts Institute of Technology (MIT) have developed new ways to fabricate lithium ion batteries with performance characteristics that bridge the gap between standard power cells and capacitors. The technology takes advantage of carbon nanotubes coated in oxygen-containing chemicals, a method which allows the tubes to work as the positive electrode.
Within days, air travellers will no longer be able hold loose lithium batteries in their luggage, the US Department of Transportation says. As of January 1st, batteries will either have to be inserted into a phone, notebook or other electronic device, or else dropped into a plastic bag, and bundled along with carry-on baggage in a limit of two batteries per passenger. The issue, according to the Federal Aviation Administration, is that if a lithium battery catches fire while in a cargo hold, current extinguishing systems are unable to stop the blaze. The National Transportation Safety Board insists that it cannot rule out lithium as the source of a plane fire at the Philadelphia International Airport in 2006.

Xcode updated for Git security
Apple on Friday patched two known critical vulnerabilities in its Xcode development tool that were concerned with the Git source code management client portion of the program. For unknown reasons, Apple waited seven weeks to update the version of Git shipping with the command-line tools in Xcode to v2.7.4, released by Git developers on March 17 to address the vulnerabilities. The flaw, now corrected, could allow for cloning a repository with a specially-crafted file structure, giving attackers a chance to execute malicious code on systems where cloning operations were initiated, reports Computerworld. The Command Line Tools package is not installed by default on OS X, but users have the option of installing it, and in some cases were forced to disable Git until the tools were updated. http://apple.co/24BQJP3

GoPro revenue drops, Karma drone delayed
Action camera maker GoPro announced its first quarter results on Thursday, and the news was largely bad. While unit sell-through of the cameras was close to the year-over-year compare, revenues dropped 49.5 percent from Q1 last year, though was slightly above the company's guidance. Overall, the company lost $107 million in GAAP net income, and margins declined to 32.5 percent from 45.1 percent in the year-ago quarter. The company further announced that it would be delaying its planned Karma drone product until this winter, which will likely further impact next quarter's results. The upside of the delay, said GoPro Founder and CEO Nicholas Woodman, is that the Karma will now benefit from debuting just before the holiday buying season. http://bit.ly/1OgpdgD
Netflix iOS app now offers cell-data controls
In a new update to its iOS app on Thursday, subscription entertainment service Netflix has introduced new user controls for streaming over cellular networks to prevent overages, throttling, or other usage issues caused by the high data rate of streamed HD video. Users can choose from a given amount of streaming video that "costs" 1GB of cellular data, which lowers video quality to allow as much as four hours of video per GB (the "automatic" setting provides three hours, while higher quality settings reduce the time to two hours, or one hour at the best setting). In addition, the updated app now offers more 3D Touch options from the app icon, beyond the "peek and pop" previews for video. http://apple.co/24AD1vR

Lunch with Cook auction nets $515K
The Charitybuzz auction that offered lunch with Apple CEO Tim Cook at Apple HQ and a pair of passes to a future Apple event (winner's pick) has ended with a high bid of $515,000, the highest amount the annual auction has fetched since 2013. Proceeds of the auction will benefit Cook's preferred charity, the Robert F. Kennedy Human Rights organization, where Cook was recently named to the board of directors. The winner, who was unnamed, will be responsible for their own transportation and accommodation, and Cook has up to a year to schedule the meeting -- making it possible that the winner will be among the first to dine with Cook in the new Campus 2 cafeteria, which is set to open along with the rest of the new facility early next year. http://bit.ly/236Wf9N
