Harvard creates a material that lets light go ‘infinitely fast’

Researchers at Harvard University announced recently that they had successfully developed a means of manipulating light at the nanoscale, which could lead to photonic-based ( rather than electronic ) telecommunications. Think, ubiquitous fiber optics. The team reportedly developed an on-chip metamaterial made from silicon pillars embedded in polymer and wrapped in gold film that exhibits a refractive index of zero. In English, that means that the phase of light passing through this material can travel infinitely fast without violating the known laws of physics. Source: Harvard University

Update Facebook on iOS now to keep it from draining your battery

Facebook users on iOS have had a sneaking suspicion that the app was starting to misbehave, to the detriment of their phone’s battery life. After saying it was looking into the issue, Facebook has now confirmed the problem and pushed out an update to the iOS app to help offer some relief. Facebook engineering manager Ari Grant said as much in a post today on (where else) Facebook, saying that the company “found a few key issues and have identified additional improvements, some of which are in the version of the app that was released today.” While there’s more Facebook says it can do to lessen battery draing, updating the app today should provide some immediate relief.

How Twitter helped make the ‘Archer’ pinball game a reality

Pinball FX creator Zen Studios released a bundle this week featuring tables from Archer , Family Guy , Bob’s Burgers and American Dad . The pack, called Balls of Glory , is available now across PS3, PS4, Vita, Xbox 360, Xbox One, Windows 10, Steam, Android and iOS ( whew ). And all of this exists because of a tweet, as Zen Studios VP of Publishing Mel Kirk explains.

Facebook expands search to all 2 trillion of its posts

Facebook announced on Thursday that it will expand its search function to include every publically-available post in its archive, not just those of your friends and liked Pages. But this won’t simply be a firehose of information , Facebook will reportedly segregate and stack results depending on the source. The top of the search results will be dominated by trusted sources like professional news outlets (CNN and the like). Below that section will be posts from your friends, presumably providing color commentary and insightful discussion of the headlined news — or, if they’re anything like my friends, it’ll quickly devolve into GIF wars and poop jokes. And at the bottom of the stack will be a Digg-like section of aggregated links related to the search topic. The returned results are reportedly personalized for each user based on 200 search factors. These factors include what subjects and Pages you like as well as your personal information and search history. This change comes in response to criticism of FB’s existing search feature, which has been characterized as an “echo chamber.” By at least exposing users to thoughts and opinions beyond those of their immediate social circle, FB hopes to improve the overall discussion about breaking news. “You don’t just see what your friends and people around you are saying, ” Tom Stocky, VP of Search, told TechCrunch . “You see the stories of people on the ground. It gives us a different level of perspective.” Though, if this new search function is anything like the bedlam of breaking news that is Facebook’s Signal news service, you might want to just stick with Google.

Vudu starts streaming 4K movies to the Roku 4

Vudu’s 1080p HDX streams were once considered high quality for streaming movies over the internet, (now they’re even watchable on phones ) but in the last year Amazon and Netflix surpassed them with 4K resolution and even HDR. Now Vudu is stepping up its game with some 4K flicks, currently available only through the new Roku 4 . For the moment it has 12 movies viewable in 4K (check the list after the break), with prices of $10 for a rental and $25 – $30 to purchase. According to Vudu, you’ll need an 11Mbps connection to stream the high-res versions that it’s marked Vudu UHD. The option will be coming to other platforms including Vizio’s 4K TVs soon, and for the ones that can handle it, there’s support for HDR and Atmos surround sound too. 1. San Andreas 2. Man of Steel 3. Edge of Tomorrow 4. The Lego Movie 5. Magic Mike XX 6. Jupiter Ascending 7. Sherlock Holmes 8. Sherlock Holmes: A Game of Shadows 9. The Great Gatsby 10. Into the Storm 11. Focus 12.

Scientists stretch metal to make it stronger

You’d think that stretching metal would make it weaker, but just the opposite is true… on a very small scale. Researchers have developed a technique that pulls nanoscopic metal crystals to eliminate defects. By gently and repeatedly stretching the crystal, scientists move “dislocations” (rows of atom-level defects) to free surfaces, where they’re ultimately forced out. The result is a metal that is considerably less likely to crack or otherwise fail over time. You may not see this technique used to improve larger (that is, visible) metal, like what you see in buildings or vehicles. The same trick that improves nanoscale metal tends to make things worse at the macro level. However, it could be very helpful for processors and any other device where even the tiniest breaks could cause big problems. Don’t be surprised if you’re one day using electronics that last for years longer than you’re used to. Source: Carnegie Mellon University , PNAS

Fitbit trackers can be hacked in ’10 seconds’

Fitbit trackers have a whopper of a vulnerability that can let somebody within Bluetooth range quickly hack them, according to security company Fortinet . Worse yet, once the attackers are in, the device will infect any computer that tries to sync with the device. Via Twitter , Senior Fortinet researcher Axelle Apvrille told Engadget “you don’t need physical access (to the tracker), but you do need to be close (Bluetooth range). It does not matter if it is paired (to another device) or not.” When in range, a bad actor could infect the device in as little as 10 seconds. Apvrille informed Fitbit of the vulnerability back in March, but the wearable outfit has yet to fix the issue, according to the Register . In addition, the vulnerability remains in the wearable even after it’s reset. Once infected, the device can install a virus, trojan or other vulnerability on your computer, even days later. “An attacker sends an infected packet to a fitness tracker nearby at Bluetooth distance then the rest of the attack occurs by itself, without any special need for the attacker being near, ” Apvrille said . While the Fitbit uses encryption, the Bluetooth transmitter itself is apparently wide open, allowing attackers in. If you want to find out more, Apvrille will present her findings via a video demonstration at the 2015.Hack.lu conference tomorrow in Luxembourg. @AaronIsSocial you don’t need physical access, but you need to be close (bluetooth range). It does not matter if it is paired or not. — Axelle Ap. (@cryptax) October 21, 2015 Via: The Register Source: Axelle Apvrille (Twitter)

Waze’s maps and traffic app gets a cleaner and smarter design

Waze is one of the most popular maps and traffic apps on iOS and Android. For good reason, too: It’s fast, intuitive and, often times, more accurate than the highly rated Google Maps. Today, Waze’s making its mobile application even better, thanks to an overhaul designed to offer a cleaner, prettier user interface and quicker access to useful actions. With a single tap, you can now send directions, location or estimated time of arrival to your contacts. You can also get traffic-based reminders, making it easier to get to any destination on time — as long as your calendar is synced with Waze. Last but not least, this new version of the app “significantly” reduces battery consumption, according to the company; if true, that’ll definitely be appreciated by users who rely on the app for their daily commutes or casual trips. The 4.0 update is already available for iOS , while Android’s expected to get it ” soon .” [Image credits: AFP/Getty Images] Source: Waze

Lenovo’s flagship Yoga 900 laptop is an improvement in every way that matters

The Lenovo Yoga 3 Pro was one of our favorite laptops of 2014, but mostly for impractical reasons: At 2.62 pounds and half an inch thick, it was exceptionally thin and light, even for an ultraportable, but it suffered from relatively short battery life and performance that trailed some rivals. Fortunately, the company just announced a new flagship, the Yoga 900, and it appears to improve on its predecessor in every way that matters. For starters, it movies from one of Intel’s low-powered Core M chips to a sixth-gen Core i5 or i7 CPU. Between that and a new option for 16GB of RAM, the performance here should be faster than it was just a year ago. At the same time, Lenovo didn’t have to compromise much on weight: the Yoga 900 is just heftier, at 2.8 pounds and 14.9mm (0.59 inch) thick.Slideshow-330250 That addresses performance. As for battery life, Lenovo bumped up the battery capacity by about 50 percent, promising between eight and nine hours of runtime. Last year’s model lasted around seven and a half hours in our tests, so if the new model can indeed reach nine, that would be a marked improvement. Lenovo also increased the base storage from 128GB to 256GB, and plans to offer a 512GB on the highest-end configuration. This time, too, the Yoga starts with 8GB of RAM, going up to 16GB on the top-tier model. Additionally, Lenovo made a couple tweaks to the hardware, though this was admittedly one of the Yoga 3 Pro’s strong points in the first place. For one, Lenovo ditched last year’s five-row keyboard for a six-row setup, allowing the user to adjust things like brightness from the top row without holding down the Function key. Also, though the”Watchband” hinge in the back looks the same, Lenovo tightened it so that it feels sturdier when you’re flipping the 3, 200 x 1, 800 screen into different usage modes. Indeed, I noticed in my hands-on that the flex I complained about in my review was gone; no more creaking sound when you rotate the display back into tablet mode.Slideshow-330251 The Yoga 900 starts at $1, 200, and is available today at Best Buy and on Lenovo’s website. Colors include gold, silver and “clementine orange, ” and this time, the watchband hinge around back matches the rest of the chassis. Given that this is the direct replacement to one of our favorite laptops from last year, you can bet we intend to review this as soon as we’re able to get our hands on one. Until then, enjoy the hands-on photos.

Xiaomi brings Segway to the masses with $315 Ninebot mini

We’d be throwing money at our screen right now, if we could. Chinese company Xiaomi has launched a small Segway device, the Ninebot mini , for a mere $315 (£203), on the same day it revealed a $790, 60-inch 4K TV . If you’ll recall, Xiaomi is a major investor in Ninebot, the China-based company that recently purchased Segway . This is the first device the companies have launched since the acquisition, and while the self-balancing scooter looks a bit like the original , it costs less than a twentieth the price. The performance is nothing to sneeze at, though — it can move at up to 16km/h (10 mph), tackle 15 degree hills and run up to 22 km on a single charge. It’s portable at 12.8 kilograms (28 pounds) and “fits easily in the trunk of your car, ” according to Xiaomi. You can also upgrade the firmware and monitor your speed, traffic data and systems via a smartphone. Sure, Xiaomi’s marketing the Ninebot mini as a “cool youth toy, ” according to the rough translation — but it looks like it could get you around nicely, too. You’ll have to put your checkbook away for now, though. The self-balancing device is coming to China on November 3rd, but there’s no word on Xiaomi’s plan for a wider launch. That said, Ninebot has updated its French website with an offer to be “informed of the availability.” That means it’ll likely be sold in Europe, so it may come to the US after all. We’ve reached out to Xiaomi for more information. Via: Engadget Chinese Source: Xiaomi (translated)
