All-bacterial battery makes a nutrient when charged, eats it to discharge

Diagram of a microbial fuel cell that runs on acetate, one half of the bacterial battery described here. (credit: Oak Ridge National Lab ) The chemical that powers most of our cellular processes is produced through something called the electron transport chain. As its name suggests, this system shuffles electrons through a series of chemicals that leaves them at a lower energy, all while harvesting some of the energy difference to produce ATP. But the ultimate destination of this electron transport chain doesn’t have to be a chemical. There are a variety of bacteria that ultimately send the electrons off into the environment instead. And researchers have figured out how to turn these into a fuel cell, harvesting the electrons to do something useful. While some of these designs were closer to a battery than others, all of them consumed some sort of material in harvesting the electrons. A team of researchers in the Netherlands figured out how to close the loop and create an actual bacterial battery. One half of the battery behaves like a bacterial fuel cell. But the second half takes the electrons and uses them to synthesize a small organic molecule that the first can eat. Its charging cycle is painfully slow and its energy density is atrocious, but the fact that it works at all seems rather noteworthy. Read 11 remaining paragraphs | Comments

Nvidia unveils first Pascal graphics card, the monstrous Tesla P100

The first full-fat GPU based on Nvidia’s all-new Pascal architecture is here. And while the Tesla P100 is aimed at professionals and deep learning systems rather than consumers, if consumer Pascal GPUs are anything like it—and there’s a very good chance they will be—gamers and enthusiasts alike are going to see a monumental boost in performance. The  Tesla P100 is the first full-size Nvidia GPU based on the TSMC 16nm FinFET manufacturing process—like AMD, Nvidia has been stuck using an older 28nm process since 2012—and the first to feature the second generation of High Bandwidth Memory (HBM2). Samsung began mass production of faster and higher capacity HBM2 memory back in January. While recent rumours suggested that both Nvidia and AMD wouldn’t use HMB2 this year due to it being prohibitively expensive—indeed, AMD’s recent roadmap suggests that its new Polaris GPUs won’t use HBM2 —Nvidia has at least taken the leap with its professional line of GPUs. The result of the P100’s more efficient manufacturing process, architecture upgrades, and HBM2 is a big boost in performance over Nvidia’s current performance champs like the Maxwell-based Tesla M40 and the Titan X/Quadro M6000. Nvidia says the P100 reaches 21.2 teraflops of half-precision (FP16) floating point performance, 10.6 teraflops of single precision (FP32), and 5.3 teraflops (1/2 rate) of double precision. By comparison, the Titan X and Tesla M40 offer just 7 teraflops of single precision floating point performance. Read 9 remaining paragraphs | Comments

A spiritual successor to Aaron Swartz is angering publishers all over again

Aaron Swartz would be proud of Alexandra Elbakyan. The 27-year-old is at the center of a lawsuit brought by a leading science publisher that is labeling her a hacker and infringer. (credit: Courtesy of Alexandra Elbakyan) Stop us if you’ve heard this before: a young academic with coding savvy has become frustrated with the incarceration of information. Some of the world’s best research continues to be trapped behind subscriptions and paywalls. This academic turns activist, and this activist then plots and executes the  plan. It’s time to free information from its chains—to give it to the masses free of charge. Along the way, this research Robin Hood is accused of being an illicit, criminal hacker. This, of course, describes the tale of the late Aaron Swartz . His situation captured the Internet’s collective attention as the data crusader attacked research paywalls. Swartz was notoriously charged as a hacker for trying to free millions of articles from popular academic hub JSTOR. At age 26, he tragically committed suicide just ahead of his federal trial in 2013. But suddenly in 2016, the tale has new life.  The Washington Post   decries it as academic research’s Napster moment, and it all stems from a 27-year-old bioengineer turned Web programmer from Kazakhstan (who’s living in Russia). Just as Swartz did, this hacker is freeing tens of millions of research articles from paywalls, metaphorically hoisting a middle finger to the academic publishing industry, which, by the way, has again reacted with labels like “hacker” and “criminal.” Read 30 remaining paragraphs | Comments

Reddit removes “warrant canary” from its latest transparency report

(credit: Cyrus Farivar) Reddit has removed the warrant canary posted on its website, suggesting that the company may have been served with some sort of secret court order or document for user information. At the bottom of its 2014 transparency report , the company wrote: “As of January 29, 2015, reddit has never received a National Security Letter, an order under the Foreign Intelligence Surveillance Act, or any other classified request for user information. If we ever receive such a request, we would seek to let the public know it existed.” That language was conspicuously missing from the 2015 transparency report that was published Thursday morning.

Cops: Lottery terminal hack allowed suspects to print more winning tickets

Six people have been charged in what prosecutors say was a scheme to hack Connecticut state lottery terminals so they produced more winning tickets and fewer losing ones. At least two of the suspects have been charged with felonies, including first-degree larceny, first-degree computer crimes, and rigging a game, according to an article published by The Hartford Courant . The suspects allegedly owned or worked at retail stores that produced winning tickets in numbers that were much higher than the state average. Of tickets generated at one liquor store, for instance, 76 percent were instant winners in one sample and 59 percent in another sample. The state-wide average, meanwhile, was just 24 percent. After manipulating the terminals, the suspects cashed the tickets and took the proceeds, prosecutors alleged. The charges come several months after lottery officials suspended a game called the 5 Card Cash after they noticed it was generating more winning tickets than its parameters should have allowed. The game remains suspended. Investigators say more arrests may be made in the future. Almost a year ago, prosecutors in Iowa presented evidence indicating the former head of computer security for the state’s lottery association tampered with lottery computers prior to buying a ticket that won a $14.3 million jackpot.

Rage-quit: Coder unpublished 17 lines of JavaScript and “broke the Internet”

(credit: Photo illustration by Aurich Lawson) It all started with a request from the developers of a messaging application to an open-source developer to change the name of a library. It ended with JavaScript developers around the world crying out in frustration as hundreds of projects suddenly stopped working—their code failing because of broken dependencies on modules that a developer removed from the repository over a policy dispute. At the center of it all is npm, Inc. , the Oakland startup behind the largest registry and repository of JavaScript tools and modules. Isaac Schlueter, npm’s creator, said that the way the whole thing shook out was a testament to how well open source works—the missing link was replaced by another developer quickly. But many developers are less than elated by the fact that code they’ve become dependent on can be pulled out from under them without any notice. The disruption caused by the wholesale unpublishing of code modules by their author, Azer Koçulu, was repaired in two hours, Schlueter told Ars, as other developers filled in the holes in the repository. The incident is, however, prompting Schlueter and the team at nmp Inc. to take a look at how to prevent one developer from causing so much collateral damage. Read 21 remaining paragraphs | Comments

9.7-inch iPad Pro and iPhone SE both have 2GB of RAM

Enlarge / The 9.7-inch iPad Pro isn’t quite the equal of the 12.9-inch version. (credit: Andrew Cunningham) Apple has started distributing both the iPhone SE and the 9.7-inch iPad Pro to journalists, and one of the first things to come to light has been the amount of RAM in each device. Memory in iDevices has a big impact on performance and general usability, but Apple almost never actually talks about it so we need to have hardware in hand before we can get the full story. The good news is that the iPhone SE has the same 2GB of RAM as the iPhone 6S and 6S Plus despite its smaller size and lower price. The not as good news is that the 9.7-inch iPad Pro has the same 2GB of RAM as the iPad Air 2, not the 4GB of RAM on offer in the 12.7-inch version. RAM doesn’t have quite the same effect in an iOS device as it does in laptops and desktops—iOS was originally designed for low RAM devices and even though current iPhones and iPads have much more RAM than the 128MB in the first iPhone, the OS is still aggressive about ejecting apps from memory. Giving an iPhone or iPad more RAM doesn’t necessarily speed up general performance, but it does mean that apps and browser tabs need to be ejected from memory less often. Today this is particularly beneficial in Safari, which needs to reload tabs when they’re ejected from RAM—at best this process adds a couple extra seconds to what ought to be a simple tab switch, and at worst you don’t have connectivity and so can’t see the tab you’re trying to open.

10 more OEMs pledge to make auto-braking standard in new cars

(credit: Ford) The number of car makers committed to making automatic emergency braking a standard feature on all new cars has doubled this week. On Thursday the National Highway Traffic Safety Administration and the Insurance Institute for Highway Safety announced that 20 manufacturers are now onboard with the plan, which will see AEB systems installed throughout their model range by 2022. In September of last year, we reported that 10 OEMs had already made the pledge. In the past, government mandates were needed to spread advanced driver safety aids like airbags or electronic stability control systems beyond the luxury cars in which they first appeared. In this case, the auto industry has gotten ahead of possible NHTSA regulation and looks set to implement AEB itself. Speaking at an event last Fall , NHTSA Administrator Mark Rosekind said that NHTSA wanted to see OEMs implement AEB as quickly as possible. “Safety,” he said, “should not be a luxury item. Its an obligation for all of us.” Whether 2022 qualifies as “quickly” may be a matter of opinion, but may be reasonable given the long product development lifecycles of new vehicles.

LAX to SFO flights from United Airlines move to biofuel blend

(credit: United) On Friday, United Airlines announced that its flights between Los Angeles International Airport and San Francisco International Airport will now be partly powered by a biofuel mix supplied by an LA-based company called AltAir Fuels. United runs four or five flights between LAX and SFO every day, and it will fill these planes up with a combination of 30 percent biofuel and 70 percent traditional jet fuel, according to the Washington Post . The biofuel portion of the mix will be made with a range of biological source materials “from used cooking oil to algae,” the Post writes; it was developed with funding from the Defense Advanced Research Projects Agency (DARPA). The airline has agreed to purchase 15 million gallons of the mix over the next three years from AltAir. Still, the Los Angeles Times points out that United burned through 3.2 billion gallons of traditional jet fuel last year, so that 15 million gallons is just a proverbial drop in the jet fuel barrel.

16 years later, Blizzard is still patching Diablo II

No rest for the weary. These days, you’re lucky if some titles from certain big publishers get a year or two of post-launch online support for their games before they’re unceremoniously dropped . And then there’s Diablo II . Blizzard issued a new version 1.14 patch for the nearly 16-year-old game Thursday, five years after the game was last officially updated (not to mention, four years since the game’s sequel launched with its own attendant post-release problems and patches ) The new Diablo II patch doesn’t add any new gameplay features, balance tweaks, or anything like that. Instead, Blizzard has added compatibility with modern operating systems like Windows 10 and OS X. But Blizzard says it’s working on improvements to the game’s “cheat-detection and hack-prevention capabilities” and hints at more improvements to come. “There is still a large Diablo II community around the world, and we thank you for continuing to play and slay with us,” Blizzard writes . “This journey starts by making Diablo II run on modern platforms, but it does not end there. See you in Sanctuary, adventurers.” Read 2 remaining paragraphs | Comments
