An anonymous reader writes "A team of researchers reports they can't reproduce the most important claim from 2010's controversial 'arsenic bacteria' paper — they find no arsenic in the bug's DNA. Meanwhile, other scientists are looking at different aspects of the bug and at arsenic in biology in general."

ForgedArtificer writes "A recent eruption on the sun will be exposing Earth to the strongest radiation storm seen since 2005. [The storm] will potentially disrupt communications and put high-flyers at risk of radiation exposure." Says Spaceweather.com: "On the NOAA scale of radiation storms, this one ranks S3, which means it could, e.g., cause isolated reboots of computers onboard Earth-orbiting satellites and interfere with polar radio communications." According to the Christian Science Monitor, "NOAA's Space Weather Prediction Center has issued a geomagnetic storm watch, and the agency's deputy, Kathy Sullivan, said that polar flights are expected to be re-routed."

For the first few years of its existence, it would have been fair to say that Canonical was essentially polishing, packaging and publishing Debian Linux (and Gnome) to create the base Ubuntu desktop, to great acclaim. For the past few years, though, the company has pushed new looks and new applications (cf. Unity and Ubuntu TV), and refused to stick with prettifying existing interfaces. Now, Barence writes with this excerpt from PC Pro: "Ubuntu is set to replace the 30-year-old computer menu system with a 'Head-Up Display' that allows users to simply type or speak menu commands. Instead of hunting through drop-down menus to find application commands, Ubuntu's Head-Up Display lets users type what they want to do into a search box. The system suggests possible commands as the user begins typing – entering 'Rad' would bring up the Radial blur command in the GIMP art package, for example. HUD also uses fuzzy matching and learns from past searches to ensure the correct commands are offered to users. Canonical's Mark Shuttleworth told PC Pro the HUD will make it easier for people to learn new software packages, and migrate from Windows to Linux software without having to relearn menus. The HUD will first appear in Ubuntu 12.04."

theodp writes "What would you say if you went to join a gym and were told that it could cost you anywhere from $360 a year to $68,000 a year for the exact same usage? Don't be ridiculous, right? Well, that's really not so different from what the potential costs of streaming video on an AT&T smartphone are. According to AT&T's Data Usage Calculator, 1,440 minutes worth of streaming video consumes 2.81GB, which — if you manage to keep Netflix fired up all day and night — would result in a $360 annual bill under the grandfathered $30-monthly-unlimited-data plan, or $68,376 under the new $20-monthly-300MB plan. Still, that didn't stop a spokesman from characterizing the new AT&T data plans as 'a great value' for customers."

While he was at the International Auto Show in Detroit, Timothy Lord looked at the Tesla Model S, then the CODA electric car. Now he shows us the latest Smart (brand) gas and electric vehicles, including a "concept car" he doesn't think will make it into production.

An anonymous reader writes "An article by Andy Young in The Kernel makes the case that lessons in programming should be compulsory learning for modern school kids. He says, 'Computers help us automate and repeat the many complicated steps that make up the search for the answer to some of our hardest problems: whether that's a biologist attempting to model a genome or an office administrator tasked with searching an endless archive of data. The use of tools is a big part of what make us human, and the computer is humanity's most powerful tool. ... The computer makes us more efficient, and enables and empowers us to achieve far more than we ever could otherwise. Yet the majority of us are entirely dependent on a select few, to enable us to achieve what we want. Programming is the act of giving computers instructions to perform. This is true whether the output is your word processor, central heating or aircraft control system. If you can't code, you are forced to rely on those that can to ensure that you can benefit from the greatest tool at your disposal.'"

darthcamaro writes "In any given year, Slashdot always has stories about how a researcher hacked a browser in only a few minutes at the Pwn2own hacking challenge. This year the rules are a bit different, and instead of hackers winning for just one vulnerability, the rules allow for multiple vulnerabilities to be presented. The winner isn't the first one to hack a browser, but is the one that can hack the browser the most. 'In the past, due to the way the competition was architected, we had lots of sensationalist headlines, things like "Mac hacked in three seconds,"' said Aaron Portnoy, Manager of the Security Research Team at HP TippingPoint. 'We don't think that type of sensationalism was representative of all the research that was going on.'"

A Commentor writes "Perhaps to balance the good news with the Supreme Court ruling on GPS, a judge in Colorado has ordered a defendant to decrypt her hard drive. The government doesn't have the capability to break the PGP encryption, and 'the Fifth Amendment is not implicated by requiring production of the unencrypted contents' of the defendant's computer."

An anonymous reader sends this excerpt from Nextgov: "Hackers, possibly from abroad, executed an attack on a Northwest rail company's computers that disrupted railway signals for two days in December, according to a government memo recapping outreach with the transportation sector during the emergency. ... While government and critical industry sectors have made strides in sharing threat intelligence, less attention has been paid to translating those analyses into usable information for the people in the trenches, who are running the subways, highways and other transit systems, some former federal officials say. The recent TSA outreach was unique in that officials told operators how the breach interrupted the railway's normal activities, said Steve Carver, a retired Federal Aviation Administration information security manager, now an aviation industry consultant, who reviewed the memo."

New submitter turkeyfish writes "UK scientists are reporting today in the journal Nature Geoscience that a huge bulge of freshwater is forming in the Western Arctic Ocean caused by a large gyre of freshwater. The gyre appears to indicate that the ice is becoming thin enough over the Arctic Ocean that the wind is beginning to affect the motion of water under the ice. A sudden release of this water or its emergence to the surface will greatly accelerate the melting of the remaining polar oceanic ice and likely alter oceanic circulation in the North Atlantic."

sl4shd0rk writes "In contrast to the Apple's iron-fisted control over their App store, the Android Market is much more open. Google does, on occasion, remove apps it deems inappropriate, such as emulators, legally-questionable music services, tethering apps and one-click root apps. But if Koushik Dutta of CyanogenMod fame has his way, these heretic apps may have a home after all. Dutta plans an 'underground' Android Market complete with an approval process to weed out malicious applications; something Google doesn't do. Ideally, this will give Android users a more trustable source from which to get applications without having to resort to dictatorial software control."

milbournosphere writes "Russia and NASA are reportedly in talks to create a base on the Moon. They're looking to create either a facility on the Moon itself or a permanent space station in orbit around the moon. 'We don't want man to just step on the Moon,' agency chief Vladimir Popovkin said in an interview with Vesti FM radio station. 'Today, we know enough about it. We know that there is water in its polar areas,' he added. 'We are now discussing how to begin [the Moon's] exploration with NASA and the European Space Agency.'"
