Samsung tech would nearly double your phone’s battery life

Don’t like that your Galaxy S6 conks out before you’re finished for the day? Samsung might offer some relief in the future. Its scientists have developed lithium-ion battery technology that promises much longer-lasting power packs. They use a silicon anode (which promises much more capacity than a typical battery), but grow layers of graphene on top to improve the density and longevity that would otherwise suffer. In experiments, they got batteries that were 1.5 to 1.8 times denser than what you get today. If your smartphone barely makes it 12 hours before giving up the ghost, this would theoretically give you 21 hours — enough that you wouldn’t have to panic if you forgot to plug in before bedtime. You shouldn’t count on this upgrade showing up in the Galaxy S7 (or any other gadgets) for a while. This is still a research project, and it could take years before Samsung translates its breakthrough into real-world products. Should everything go smoothly, though, this could be crucial in just about any situation where adding a bigger battery just isn’t an option. Besides mobile devices, you could get electric cars that match the range of their gas-powered counterparts.

AMD’s Project Quantum Gaming PC Contains Intel CPU

nateman1352 links to an article at Tom’s Hardware which makes the interesting point that chip-maker AMD will offer Intel — rather than AMD — CPUs in their upcoming high-end gaming PC. (High-end for being based on integrated components, at least.) From the article: Recently, AMD showed off its plans for its Fiji based graphics products, among which was Project Quantum – a small form factor PC that packs not one, but two Fiji graphics processors. Since the announcement, KitGuru picked up on something, noticing that the system packs an Intel Core i7-4790K “Devil’s Canyon” CPU. We hardly need to point out that it is rather intriguing to see AMD use its largest competitor’s CPU in its own product, when AMD is a CPU maker itself. Read more of this story at Slashdot.

Engineers Just Broke the Capacity Limit For Fiber Optic Transmission

So, that Internet apocalypse that’s going to befall us when the our fiber optic cables max out? Maybe not so much. On Thursday, engineers reported in Science that they’d broken the “capacity limit” for fiber optic transmission, opening the door to future networks that carry more data further at lower costs.

How Etak Built a Car Navigation System In 1985

harrymcc writes: Thirty years ago, a startup called Etak released the Navigator, an in-car navigation system. It provided turn-by-turn driving directions despite the fact that GPS did not exist, and stored its maps–which Etak had to create itself–on cassette tapes. And some of its data and technologies are still in use in today’s navigation apps. Over at Fast Company, Benj Edwards tells this amazing story. I remember reading about (and lusting over) this system back then, in the much-missed DAK catalog. Read more of this story at Slashdot.

How a file format brought an industry to its knees

MP3. It’s the format that revolutionized the way music’s been consumed since the late ’90s. When Karlheinz Brandenburg, a German acoustics engineer, discovered that an audio file could be compressed down to one-twelfth of its original size without distortion, he created the file-shrinking technology. Stephen Witt’s debut book, How Music Got Free , traces all digital music piracy back to the invention of that format, which inadvertently made it possible for people to download and share music illegally. The book details the science and struggle behind the widely used audio technology. And his investigation uncovers the politics and the manipulative men who kept MP3 files from seeing the light of computer screens for years. When the MP3 format became accessible, after a long corporate battle, it eventually led to the rise of music piracy and simultaneous demise of CDs. But Witt reveals more than just the technology that systematically tore the music industry to pieces. He narrows the story down to two men at opposite ends of the same spectrum: Doug Morris, one of the most powerful record label CEOs in the industry, who made rap music top the charts and eventually led the fight against piracy; and Dell Glover, a factory worker at a Universal Music CD-manufacturing unit in North Carolina, who leaked about 2, 000 albums, made Eminem change his album release date and became one of the biggest pirates in the largest underground scene, Rabid Neurosis (RNS). When pirated music found its way online in the ’90s and early 2000s, almost all of it came through RNS, which relied on Glover’s access to the CDs weeks before release. Tech-savvy teens spent hours scouring the internet and loved having access to music before it hit the record stores, even if that meant jeopardizing the careers of the very artists they worshiped. At the time, it became virtually impossible to not download the MP3 files or know someone who did. Witt’s book is filled with nostalgic moments for a generation that grew up on piracy. But it’s also informative for people who skipped that phase completely. He draws parallels between the inventions, the decisions and the theft that led to the downfall of the booming music industry — an industry that never quite regained its glory. I caught up with the author to get the lowdown on his expansive work on digital piracy and his views on music streaming. When and why did you get interested in music piracy? I showed up at [the University of Chicago] in 1997 with a 2GB hard drive and by the end of the year, I filled it with pirated MP3s. This was really the first time in history that you could do it. Even a couple of years earlier the technology wasn’t there. Over the next decade, I was a serial media pirate. I just hoarded tons of stuff. I was on all the underground pirate networks. It was such a thoughtless action to go and take something from the internet; I never really thought about who might have put it up there in the first place. As I got older, around 2010-2011, I wondered where all this stuff came from. When I started investigating it, I found all this fascinating stuff that turned into this book. The original iPod from 2001 Your book underscores the technology that led to music piracy and the corporate drama behind it. It was fascinating and frustrating to know that half a dozen German engineers sat on a gold mine but couldn’t share it with the world for years because their invention was systematically and viciously suppressed. Why was the music industry snubbing MP3 even though it was clearly a superior format to the MP2, which was widely accepted? The music industry was [made up of] technophobes. When this information [about the MP3] first became available, they rejected it multiple times. The pirates [started] providing leaked compressed music through the internet and filling a vacuum that the music industry would not. The music corporations could’ve done that. They ended up being forced to do it much later anyway. But for a long time, they had to be dragged screaming into the modern era. Now I think anyone who owns a music company is thinking 20 years ahead about distribution. They’ve learned their lesson. But at the time they were totally clueless. There’s a moment when Ricky Adar, an entrepreneur, asks Brandenburg, “Do you realize what you’ve done? You’ve killed the music industry.” Did the invention of the MP3 really destroy the industry or did it, in fact, push it to change and adopt a new way? It was a bit of both. Adar was trying to push a service similar to what we call Spotify today. This was in 1995. He faced enormous resistance from the industry and at the time it wasn’t even clear such a thing was technologically possible. When he saw the MP3, it was the first time he saw a device that actually shrunk music, but made it listenable. Previous devices did it, but they sounded pretty crappy. Why did he say it killed the industry? I think once the stuff got out, it wouldn’t be copy protectable, people would start trading it online, which is exactly what happened. The profits would disappear because you could get it for free. It pushed the industry into the future, but even today they’re only operating at about half the size that they were at the peak of compact discs in 2000. Still, it’s not clear if they’re ever gonna recover. They actually shrunk last year, even with Spotify. The music industry eventually fought back against piracy. They went after Napster for copyright infringement. The RIAA also sued Diamond Multimedia , the company that created the first-ever commercially successful MP3 player. What was going on with these lawsuits? “Apple almost acted like a money launderer for the spoils of Napster.” The judges ruled Napster was illegal, so the industry won that one. The legality of Napster wasn’t obvious at first. Now it’s clear that it was in violation of the law, but at the time there was no basis for ruling that. Simultaneously, there was a lawsuit against [Diamond] — the earliest version of the MP3 player. But the judges ended up ruling that the MP3 player was just a hard drive and they could not limit its sales. So the music industry lost that suit. When it happened there were all these music files everywhere and then [the lawsuit] made all these portable players available. Essentially, the music industry won the wrong lawsuit. Daniel Ek, founder of Spotify Napster had the potential to shrink the massive profits that the music industry was making from CD sales, but for a time it wasn’t impacting the sales at all. People couldn’t go anywhere with their downloaded files. But when the MP3 player won the lawsuit (RIAA vs. Diamond), it made digital piracy portable and even led to the launch of the iPod , right? For sure. Apple came kind of late to this. iTunes debuted in 2001. The iPod came in [later that year]. It didn’t make an impact right away, but eventually people wanted to take all these files and make them portable. The iPod made that possible. So for a time it became the best-selling gadget ever. Apple’s retail store had the highest sales per square foot of any retail business in history and a lot of it was from these $200-300 iPods. Eventually they moved to iPhone, but you can trace these developments in the global market all the way to the earliest days of piracy. It’s like I say in the book, Apple almost acted like a money launderer for the spoils of Napster. At one point in the book you say: “Controversy was temporary. Royalties were forever.” I couldn’t help but wonder how you perceive the aggressive shift from downloading to streaming services like Spotify and Tidal ? The stuff in the book is really nostalgia now. That era is closing and we’ve moved on to a new form. Instead of owning files, we license them from a large corporation; we’re at their mercy. The trade-off is that artists get paid and we get access to everything ever written instantly. It’s a pretty nice deal, but it limits the freedom of the user. What’s going on right now is that there’s more than half a dozen companies attempting to crack the music-streaming space. All of them are losing money and artists are making very little from these sites. But if they can get hundreds of millions of users to subscribe, it can work. They just have to make people willing to pay $120 a year. Half of Spotify’s subscribers are under the age of 27 and these are people who grew up with piracy, including me. I wonder if there’s an all-powerful Doug Morris-type of the streaming world? Daniel Ek — the CEO of Spotify. He’s Swedish and he founded the company in 2008 during the height of Pirate Bay frenzy. His entire mission statement for the company was to get people to pay for music again. Surprisingly enough, I would say he’s been successful in doing that. Spotify is not a sustainable business right now. It’s losing about $200 million a year and it’s paying its artists a pittance. It’s possible in the future it could evolve into a commercially viable model. It’s not there yet. But for consumers it’s been great. If they can get their goal of 40 million [paid] subscribers, which is the size of the music industry right now, they might save everyone. This interview has been condensed and edited.

Crazy fast X-ray laser catches chemical reactions in the act

Scientists at the Department of Energy’s SLAC laboratory have taken a “molecular movie” of a chemical reaction for the first time. The results of their research could give new insights into to how chemical bonds form, helping researchers better understand biological processes. To give you an idea of the difficulty of the feat, the critical part of the reaction — the breaking apart of a ring-shaped gas molecule — takes a mere 200 femtoseconds (quadrillionths of a second). To record such a rapid process, the researchers used the two mile long Linac Coherent Light Source (LCLS) to fire X-ray laser pulses a mere 25 quadrillionths of a second in duration. The molecular changes are not captured with visible light like a camera takes a picture, however. Here’s how it works: first, the chemical reaction is initiated by blasting the gas (1, 3-cyclohexadiene) with a separate, high-powered optical laser. That breaks the molecular bonds, converting it into another gas called hexatriene. While the chemical transformation is still in action, the LCLS X-ray laser strikes the altered molecule, creating a distinctive diffraction pattern that’s capture by a detector. The shape of the pattern on the detector helps scientists “infer back what’s going on the molecule, ” according to lead scientist Mike Minitti. By varying the time between the optical laser that kicks off the reaction and the X-ray laser (in 25 femtosecond increments), the team could see the chemical bonds breaking apart step-by-step. It took about 100, 000 measurements to get enough data to create a simulated “molecular movie” showing the complete transformation. It happens so fast that if it were possible to film it using a real camera, it would have to roll at around 30 trillion frames per second. “Before your eyes, a chemical reaction is occurring that has never been seen before this way, ” said Minitti. As a result, the study helped resolve “long standing questions about how this (ring-shaped) molecule actually opens up, ” he added. With the first successful observation of a rapid chemical transformation in a simple gas, the SLAC scientists plan to move onto larger molecules.

New Manufacturing Technique Halves Cost of Lithium-Ion Batteries

An anonymous reader writes: Experts in materials science at MIT have developed a new process for creating lithium-ion batteries that will drop the associated production costs by half. The researchers say fundamental battery construction techniques have been refined over the past two decades, but not re-thought. “The new battery design is a hybrid between flow batteries and conventional solid ones: In this version, while the electrode material does not flow, it is composed of a similar semisolid, colloidal suspension of particles. Chiang and Carter refer to this as a ‘semisolid battery.’ This approach greatly simplifies manufacturing, and also makes batteries that are flexible and resistant to damage, says Chiang. … Instead of the standard method of applying liquid coatings to a roll of backing material, and then having to wait for that material to dry before it can move to the next manufacturing step, the new process keeps the electrode material in a liquid state and requires no drying stage at all. Using fewer, thicker electrodes, the system reduces the conventional battery architecture’s number of distinct layers, as well as the amount of nonfunctional material in the structure, by 80 percent.” Read more of this story at Slashdot.

Apple yanks games with Confederate flags from the App Store (update)

Following the lead of other major retailers like Walmart, Amazon, Etsy and eBay in removing products featuring the Confederate flag, Apple has reportedly begun removing apps that feature the Stars and Bars from its online store. The apps most affected are, unsurprisingly, Civil War games like Ultimate General: Gettysburg and Civil War. Update : In a statement to TechCrunch , Apple said it is only removing software that uses the Confederate flag in offensive or mean-spirited ways, which violate the existing guidelines. The company says it is working with any developers of educational or historical apps that were removed to get them back in the App Store. Ultimate General’s developer confirmed via tweet that it’s app had been pulled from the App Store for that reason: Our official response about the removal of our game from AppStore. Please read at the below link:… http://t.co/1kIGlR1Jsk – Ultimate_General (@GeneralUltimate) June 25, 2015 As Polygon points out , basically any depiction of the Confederate flag (even in its proper historical context) appears to be enough for Apple to nix an offending app. What’s more, Google looks to have taken similar action and removed apps featuring the flag from Play. We’ve reached out to Apple for confirmation that the flag is the reason behind the removal of these apps and will update once they reply with comment. Apple: “We have removed apps from the App Store that use the Confederate flag in offensive or mean-spirited ways, which is in violation of our guidelines. We are not removing apps that display the Confederate flag for educational or historical uses.” Filed under: Gaming , Internet , Apple , Google Comments Via: Polygon Source: Touch Arcade

PSA: Xbox Live Gold now comes with two new Xbox One games every month

Xbox One owners will soon get a bit more value out of their optional $60 ( or less ) annual membership. Starting in July, Microsoft will begin offering two free Xbox One games to Gold members as part of its existing Games With Gold program every month. Xbox One owners will be able to download Assassin’s Creed IV: Black Flag starting on July 1 and indie puzzle-platformer So Many Me on July 16. A similar twice-monthly release schedule for free Xbox One games will continue into the future, Microsoft said. Gold members will also be able to download two Xbox 360 games each month, as they have since the program began in June of 2013. Until now, though, Microsoft has generally made only one Xbox One title available through Games for Gold each month. As usual, Xbox One Games for Gold titles claimed and downloaded during their monthly availability window will be playable as long as the Gold membership is maintained (Xbox 360 games can be kept permanently, regardless of future membership). Sony has made 46 PlayStation 4 games available through the similar PlayStation Plus program in the 20 months the system has been available in North America, increasing from a general rate of one per month in the early days to an average of three or four titles every month in 2015. Both Sony and Microsoft’s free game programs are dominated by smaller indie titles, with the occasional AAA release thrown in months after its initial release. Read on Ars Technica | Comments
