The AP adds 550,000 old newsreel clips to YouTube

The Associated Press has teamed up with British Movietone to share more than a century’s worth of newsreel footage with the denizens of the internet. The pair will upload more than a million minutes of archival clips to YouTube with the intention of creating a “view-on-demand visual encyclopedia” for the world. The 550, 000-plus stories range from footage of the 1906 San Francisco earthquake through to the bombing of Pearl Harbor. It’s not the first time that a news organization has used YouTube to take its archives online. Last year, British Pathé uploaded more than 85, 000 newsreel clips from between 1896 and 1976 to the site. Users can feel free to embed the clips in whatever story they’re working on, but we assume that re-editing the work isn’t permitted. Which is a shame, because we were hoping for some cheeky dance remixes of the footage of Prince Charles getting frisky at the Rio Carnival. Which, for no reason at all , we’ve embedded below… Filed under: HD Comments Via: The Guardian Source: AP

Nanowires help produce hydrogen fuel using sunlight

You ideally want to produce clean hydrogen fuel using clean sources, and Dutch researchers have taken a big step toward making that a practical reality. They’ve built a solar cell that uses a grid of gallium phosphide nanowires to make hydrogen gas from water. The approach gets a useful yield of about 2.9 percent in lab tests. That may not sound like much, but it’s about 10 times more effective than previous techniques and uses 10, 000 times less exotic material. It’s still going to take more refinements before this kind of technology is practical. Even hooking up silicon cells to a battery nets a 15 percent yield, for example. If scientists improve their methods, though, you could be driving hydrogen cars whose fuel is eco-friendly at every step, not just when it’s in your vehicle.

Lockheed Martin buys helicopter maker Sikorsky

Don’t look now, but Lockheed Martin just became an even larger aerospace powerhouse. The aircraft maker has acquired helicopter maker Sikorsky (best known for the UH-60 Blackhawk) for $9 billion. The two have already been partners on programs like the MH-60, but this gives Lockheed its very own rotary-wing team. If a customer wants something that flies, the company will have it covered. The buyout is poised to close by late 2015 or early 2016, provided everything goes smoothly. The union might come at a stiff price, however. Lockheed says it’s conducting a “strategic review” of both its information systems group and a chunk of its missile division — tough times in the market have led Lockheed to believe that these segments would be better-off either spun out or sold to someone else. That puts the future of more than 17, 000 workers in doubt, and that’s not including whatever jobs might be cut when the Sikorsky deal wraps up.

Intel delays next-gen chips as Moore’s law begins to crack

Intel says it’s next-gen ” Skylake ” will be delayed by six months, marking the second time in a row it hasn’t released a CPU on a two-year “Moore’s Law” cycle. That continues a trend, as last year’s 14-nanometer Broadwell chips were similarly delayed , and even Haswell and Ivy Bridge were behind schedule. Intel said that the setback for the new 10-nanometer chips was caused by the increasing complexity in building transistors that small. Addressing the elephant in the room, CEO Brian Krzanich said that “the last two technology transitions have signaled that our cadence today is closer to 2.5 years than two.” In other words, Moore’s Law needs a reboot. To address the lack of chips in the pipeline, Intel said that it’s going to release new 14-nanometer “Kaby Lake” chips based on the Skylake architecture. Krzanich said that “we expect that this addition to the roadmap will deliver new features and improved performance, and pave the way for a smooth transition to 10-nanometer.” Neverthless, he admitted that Intel is now on a “tick-tock-tick” cycle rather than a “tick-tock” as before. That bodes poorly for an already-struggling PC industry, as consumers will have less reason to get excited about new products. Intel also admitted that PC demand was weaker than expected, and expects it to get worse by year’s end. Nevertheless, it thinks the July 29 launch of Windows 10 will provide a tonic. “A lot of the really good features of Windows 10, things like Windows 10 Hello where you have facial log in, and you don’t have to use all your passwords, the Start screen… the touch usages of gaming, as the new games come to this product — those are going to run with PCs that have the latest features, ” Krzanich said. Despite the gloomy PC talk, Intel still managed to pull in a better-than-expected $13.2 billion for the quarter, thanks to a new focus on data centers, internet-of-things and memory.

iPhone encryption has locked out Manhattan cops just 74 times

You’ll frequently hear law enforcement complain that it can’t break the full-drive encryption in newer smartphone operating systems, but how often does the police run into that problem, really? Thanks to a US Senate Judiciary Committee hearing, you now have a better idea. The Manhattan District Attorney’s office has revealed that, out of the 92 cases where an iPhone with iOS 8 has been involved so far, the cops have been locked out 74 times. District Attorney Cyrus Vance portrays this as proof that officers need backdoors or other forms of guaranteed access, noting that there’s at least one case (in Illinois) where evidence from a victim’s iPhone led to a conviction. Police shouldn’t simply be told that there’s “nothing [they] can do, ” he says. Context is everything, however, and this isn’t quite as dire a situation as Vance made it out to be. The Manhattan DA typically handles 100, 000 cases a year — 0.0007 percent is a drop in the bucket. Moreover, there’s no records showing whether or not the encryption actually stopped the investigation cold. It’s possible that the security merely forced officers to rely on other forms of evidence. While there’s still a concern that clever criminals will take advantage of encryption, there’s also no data showing that there would be enough arrests to justify the reduced privacy.

Facebook says renewables will power 50% of its data centers by 2018

Facebook is stepping up its commitment to renewable energy today. While announcing a new data center in Fort Worth (above), which happens to be entirely powered by wind energy, the social network also set a new goal of having 50 percent of its data centers relying on renewables by the end of 2018. That follows an earlier self-imposed goal to have 25 percent of its data centers powered by clean energy come the end of this year. Naturally, Facebook plans to have all of its operations powered by renewable energy eventually. It’s also working together with Greenpeace — which took today’s announcement as a chance to shame Amazon for its data center energy usage — to ensure that it’s exploring new energy options properly. Facebook teamed up with Citi Energy, Starwood Energy, and Alterra Power to bring a 17, 000 acre wind farm online for its new Fort Worth data hub, which should deliver around 200 MW of energy to Texas. Facebook plans to get that new data center online by the end of 2016. Filed under: Networking , Internet , Facebook Comments Source: Facebook

Army scientists build smaller, tougher, cheaper solar cells

Army researchers at the Redstone Arsenal have announced a significant breakthrough in solar energy production. They’ve created a photovoltaic solar panel that is smaller, more robust and less expensive to build and operate than any other panel currently available. Virtually every solar panel currently in existence relies on a pure silicon construction, however the band gap (the wavelength of light that it can actually be absorbed and converted into electricity) of single crystal silicon is exceedingly narrow compared to the full spectrum shining down from the Sun. Not only does this mean that conventional panels are missing out on potential power, the ultraviolet and infrared wavelengths actively damage the panels by causing them to heat, warp and crack. The Army’s panel, on the other hand, sandwiches super thin layers of metals like silver and gold between the semiconductor layers. With these added layers, the panels offer a wider band gap for energy generation and can be tuned to reflect the harmful rays as well. What’s more, the Army’s panels generate the same amount of energy regardless of the angle that sunlight is hitting it. That means they don’t have to be affixed to expensive and motorized Sun-tracking stands. The technology is still in its very early stages, explained Wayne Davenport, Optical Sciences Function Chief of the Weapons Development and Integration Directorate, in a statement. “As with many basic research projects, the near-term benefits are sometimes yet undefined but are clearly worth the investment, ” Davenport continued. “The Army’s research laboratories at AMRDEC continue a legacy of high quality research projects and I expect to see many more of these type projects transition to the Warfighter in the future.” [Image Credit: AFP/Getty Images] Filed under: Science Comments Source: US Army
