Amazon’s latest Kindle Paperwhite packs text that’s twice as sharp

Don’t want to shell out $199 for the Kindle Voyage just to get an Amazon-badged e-reader with extra-crisp visuals? You won’t have to after today. Amazon has launched an updated version of the Kindle Paperwhite whose e-paper display touts the same 300 pixels-per-inch density as the Voyage, giving you text that’s twice as sharp as on the last-generation model without paying extra for the privilege. You’ll accordingly get easier-to-read layouts (including Amazon’s in-house font, Bookerly) that take advantage of that slicker screen. The new Paperwhite will ship on June 30th for the same $119 (with ads) as its ancestor, which undercuts Kobo’s Glo HD and makes it the sweet spot in the Kindle line. Unless you really want the Voyage’s advanced light and touch sensors, this new mid-tier model will likely be enough. Filed under: Amazon Comments Source: Amazon

GM powers data center with used Chevy Volt batteries

General Motors believes old Chevy Volt (and eventually, Bolt ) batteries have a future as backup power sources for houses and buildings that use renewable energy. In fact, the company has repurposed five old Volt batteries to help power its data center in Milford, Michigan. They store energy generated by the center’s 74-kilowatt solar array and wind turbines, and then feed the surplus back to the Milford campus grid. GM senior manager Pablo Valencia said that’s possible, because the batteries retain 80 percent of their storage capacity, even after they’re no longer ideal for cars. Just like Tesla’s Powerwall , the repurposed Volt batteries can provide the electricity a building needs during power outage: the five-battery pack, in particular, can supply enough energy to keep the data center running for up to four hours. GM doesn’t have a big supply of old EV batteries yet, so it can’t offer them as backup power sources to consumers at this point in time — the five in its possession came from early development models of the Chevy Volt. But since it’ll likely have access to loads of used batteries someday, the company has already started testing systems with unnamed partners for both commercial and non-commercial uses. “The importance of this announcement is that we are preparing for the future, ” Valencia said. “This is a preparation for that time. Typically the lifecycle of a vehicle is 10 to 12 years.” [Image credit: Argonne National Laboratory/Flickr ] Filed under: Transportation Comments Source: Reuters

LightSail solar spaceship ends test flight in fiery descent

And just like that, LightSail’s inaugural flight is over. The Planetary Society has determined that its experimental solar sailer likely entered Earth’s atmosphere (and met a fiery end) near the South Atlantic Ocean at 1:23PM Eastern on Monday. Don’t bemoan the fate of the Carl Sagan-inspired spacecraft, however. While LightSail ran into more than a little trouble on its 25-day run, its mission was ultimately a success — the only real goal was to deploy the ship’s namesake sails and prove that the vehicle was spaceworthy. The real challenge comes late in 2016, when the Society expects to fly a second model that will actually use its photon-powered sails to get around.

OS X El Capitan preview: a series of minor, but welcome improvements

When Apple revealed that the next version of OS X would be called ” El Capitan , ” I couldn’t help but laugh. I think we all did. I mean, here we were expecting the company to name its new operating system after another national park, and instead it chose a rock formation inside Yosemite that you may or may not have heard of (but that you most definitely enjoy saying out loud). In a way, though, this was fitting: OS X 10.11 ushers in a series of minor improvements to last year’s ” Yosemite ” release. The design remains virtually unchanged, and the new features aren’t particularly groundbreaking. This is a relatively small update — small enough that it doesn’t deserve to be named after another national park. Still, it’s an improvement nonetheless. I’ve been using an unfinished developer build of the OS for the past week, and though Apple continues to refine the software, I think it’s safe to say that all of the changes are nice to have, however inconsequential some of them may seem. Join me here for a first look. Windows management Mission Control For years now, OS X users have had Mission Control to get a quick view of all their open apps, and then easily switch between them. In El Capitan, this feature works mostly the same as it did before: Swipe up on the touchpad with three fingers or press F3, and you’ll see zoomed-out previews of all your open programs. As ever, there’s a so-called Spaces Bar running along the top of the screen, making it easy to jump between different desktops and full-screen apps. Once you’ve opened Mission Control, you can drag various preview windows into the Spaces Bar, giving them their own — wait for it — space. To move between spaces, you can just click on a thumbnail in the Spaces Bar, though can also swipe left and right on the touchpad with three fingers. This is how Mission Control worked in Yosemite, and indeed, none of that has changed. All told, there are very few differences here. For one thing, the previews now have a flatter look, with all the windows arranged in a single layer. That means even if your programs are overlapping on the desktop, they won’t appear that way in Mission Control. Instead, OS X keeps each preview window separate, but attempts to show them relative to where they are on the desktop. So, if Finder is sitting closest to the left side of the screen, that’s where it’ll appear in Mission Control; over on the left. In any case, this is a helpful change, but also a pretty minor one. Split View The other new thing in Mission Control is that you can use it to run two apps side by side in a split-screen mode (yep, just like in iOS 9 , which was unveiled the same day as OS X El Capitan). Much like the Snap feature in Windows 8, “Split View” in OS X involves locking two programs into place, at which point you can use a slider to resize the windows. That means you can go with a 50-50 split, or give one program more screen real estate. Each window functions independent of the other, and scales automatically as you resize it. There are two ways to enter Split View in OS X. One option, as I said, is to go through Mission Control. Start by opening one of the two apps at full-screen. Then launch Mission Control, and drag another app window on top of the full-screen app. You’ll know you’re doing it right when you see that the combined preview box has a split screen. The other way is to click and hold the green stoplight on an app that isn’t yet running at full-screen. Do that, and you’ll see half the screen glowing blue, showing you where to drop the app to snap it into place. Then, once you’re locked in, you’ll see all your other open apps in Exposé on the second half of the screen. Just click one of those preview windows to open it in split-screen mode. All of this is pretty straightforward — once you read up on how it works. Though both of these maneuvers are quick and easy to pull off, I wouldn’t describe either of them as intuitive, per se; how was I supposed to know, for instance, about the “holding the green stoplight” trick? Fortunately, exiting Split View mode is a little easier: Just click the full-screen stoplight on either of the two split-screen apps to bring them out of full-screen. Or, even better, just hit the Escape button. Spotlight With last year’s Yosemite release, OS X’s built-in Spotlight search got a lot smarter. In addition to locally stored documents, Spotlight could serve up Wikipedia previews, web search results, movie times and iTunes purchases. Yosemite also ushered in a whole new look for Spotlight: a search bar you could bring up in the center of the screen, with all the results contained neatly inside that search field. This year, it’s really just more of the same. The search bar looks the same; you can just move it around the screen or resize it. Additionally, Spotlight can give you weather forecasts, stock quotes, sports stats, public transit information, web videos and top Safari hits, which are based on your recent browsing history. For instance, if I type in “AAPL, ” I’ll see Apple’s own stock ticker symbol pop up, along with the most recent price and stats like the opening price, trading volume and 52-week high and low. For weather forecasts, you can use search terms like “weather, ” “weather Paris” or “weather Paris Thursday.” With transit, I was able to write “nearest subway” and get an accurate answer. Since I’m not a tourist, that particular use case isn’t very useful to me, although by the time El Capitan reaches a public release, it should respond to a wider range of queries. It’s a similar story with sports: Right now, Spotlight has the most data for Major League Baseball and NBA basketball, but by the time the OS launches, it should offer equally robust search for other sports as well. The only one where I didn’t have great luck was web video. Though Apple says it recognizes videos from YouTube, Vimeo and Vevo, I’ve so far had more success searching for videos on Vimeo. Even then, you’d have to know the exact title; general search terms won’t cut it. Through it all, Spotlight now responds to more natural language, including written search terms like “word documents I downloaded” or “photos I took last month.” It works well — as do most of the Spotlight tricks (well, with the exception of the web video thing). Native apps Mail Apple’s built-in Mail app has received some updates as well. When the company first unveiled these changes at WWDC last week, it focused mostly on the new gestures: the ability to swipe right on the touchpad to mark something as unread, and swipe left to delete. (Yes, just like in iOS.) Additionally, when you’re composing an email at full-screen, you can start a new, separate draft and it’ll appear as just another tab. If ever you need to put your drafts on hold while you check incoming messages, you can click outside the compose box and your drafts will collapse to the bottom of the screen, where they won’t be in the way. Meanwhile, if someone emails you and isn’t already in your contacts, Mail will prompt you to add that person to your list. It’s a similar story with events: If someone proposes a get-together, you’ll be presented with the option to create a calendar entry. Likewise, anytime somebody mentions something like a flight, you’ll see a prompt to get more information (say, flight stats) without having to open a new app. Throughout, you can use the same sort of natural-language search that you would in Spotlight — queries like “emails with attachments, ” for example. Notes Notes has also received some upgrades: many of them small, but all of them overdue. To begin, you can drag and drop various files into notes, including, but not limited to photos and PDFs. This works as promised. There’s also now an inline formatting option to turn lists into checklists, similar to what you can already do in some competing apps, like Google Keep. In addition, Apple made it so that you can share to Notes from other Mac OS X apps, including Safari, Maps, Pages, Numbers, Keynote and Photos. Lastly, there’s now a so-called attachments browser — a sort of repository for all the photos, websites and whatnot you may have saved in Notes. In other words, it’s possible to sift through everything at once without necessarily returning to the original note. Kind of reminds me of Apple’s own Messages app, where you get a separate view of all the photos you and your texting partner have uploaded throughout the conversation. Safari Some of my favorite updates are in Safari, though many would rightfully argue that these improvements aren’t necessarily novel. In fact, some appear to take after features already offered in Chrome, and other competing browsers. For instance, there’s now an option to identify which tab is playing sound. From there, you can hit a mute button on the tab itself, or click the speaker icon in the address bar. The latter option comes in handy when you have sound coming from multiple tabs — say, a song you meant to stream, and an auto-playing video ad in the other. By clicking the sound icon in the URL bar, you can see a list of all the tabs playing sound and selectively mute the one that’s bothering you. Perhaps my favorite new feature is the addition of pinned sites. They sort of form a bookmarks bar, only better: Here, these tabs can’t be closed, and because they look like shrunken buttons, they take up much less space than a regular tab. I find this comes in handy for things like Gmail, my calendar, Facebook, Twitter, Engadget and other sites I read regularly. I open these sites many times a day, so it’s worth it to have them always be open. Still, it’s nice to have them more or less out of my way when I don’t need them. Other new features: Safari has the same improved Spotlight suggestions I described earlier. Also, Safari in El Capitan will allow you to send video to an Apple TV over AirPlay, but unfortunately, this feature wasn’t yet ready for testing when I sat down to write this story. I’ll have to try that out some other time. Maps Maps has received one big update in El Capitan, and that’s public transportation data. Though Apple wouldn’t say, I suspect the company relied heavily on its purchase of HopStop here: The directions closely match what you can already get on the transit guide’s site, complete with similar options to plan your route around specific departure or arrival times. What’s unique about Maps on OS X, though, is that in addition to transportation directions, you get detailed maps that account for the fact that certain large metro hubs might have multiple exits, and might house different trains in different parts of the station. All told, it’s a handy feature: I’ve already used it several times, mostly because it feels easier to launch the Map apps than to navigate to Hopstop.com in my browser. So far, this Transit View feature covers New York, London, Toronto and the San Francisco Bay Area, plus over 300 Chinese cities. I imagine Apple will later add more metropolitan areas too. Photos When Apple rolled out Photos for Mac, the idea was that it would replace Aperture. That means the editing tools better be good. Indeed, most, if not all, the changes here involve expanding the editing options in some way. For instance, you can add locations to a single image or an entire moment; sort albums by date or title; batch-change image titles; and batch-organize faces. You’ll also be able to download third-party editing extensions from the Mac App Store, but since this feature was only announced last week, there weren’t any extensions available for me to play with as of this writing. Performance On the one hand, performance and under-the-hood tweaks are actually a big part of what makes El Capitan tick. In particular, Apple ported over “Metal, ” the graphics engine it debuted last year for iOS devices. The result, says the company, is up to a 40 percent improvement in app-load times and a fourfold boost in opening PDFs. (Photos, in particular, is supposed to see considerable speed improvements, especially as far as initial launch times go.) Apple also says that emails will download in up to half the time, and that Macs will also be able to switch apps up to twice as fast. For graphics, the company promises up to a 50 percent rendering boost and up to a 40 percent improvement in efficiency. All of these claims are worth investigating, but now’s unfortunately not the time. Not only is this an unfinished developer build, but also some of the apps (namely Safari) crashed frequently. It’s clear to me that any performance tests are fairly meaningless until Apple releases the final software to the public. Miscellaneous Even now, 2, 000 words later, there are still a few features I haven’t covered. Things like “Find My Cursor, ” which lets you find the cursor on the screen by rapidly shaking your finger over the trackpad. (I’m being a little snarky as I talk about all this, but it is in truth a useful feature: Who among us hasn’t at some point wondered just where the hell they left their cursor?) Additionally, El Capitan also brings some expanded language support, but it’s mostly for Chinese- and Japanese-speaking users. There’s now a new Chinese system font for both traditional and simplified Chinese, and the Chinese keyboard also offers regularly updated vocabulary lists. As for Japanese, OS X 10.11 automatically transforms Hiragana into written Japanese so that you don’t have to individually confirm word conversions. Lastly, Japanese speakers get four new typefaces in that language. Early thoughts Taken individually, none of the updates in OS X El Capitan are revolutionary. There simply is no killer feature this time around. But as minor as some of them may seem, they’re all at the very least nice to have, and in many cases genuinely useful (see: pinned sites, Split View and built-in transit directions). We’ll have to revisit the OS once Apple releases a final version with stable performance and all the features ready for testing. Until then, it’s clear El Capitan is a modest release, marked in part by an attempt on Apple’s part to play catch-up. Even if some of these features aren’t novel, though, they’re sure still to be appreciated by loyal Mac users — people who only use OS X, and maybe even specific Apple apps, like Safari. El Capitan isn’t a big release, then, but perhaps it doesn’t have to be. Filed under: Software , Apple Comments

Moore’s Law in action: making our machines ever more micro

Over the past few decades, engineers have leveraged Moore’s Law to the fullest, resulting in powerful ultrathin laptops and feature-rich miniature wearables . Back in 1981, a 23-pound Osborne 1 computer was considered portable, with 64KB of onboard memory. Today, smartphones weigh just a few ounces and easily pack 128GB of storage. There’s also a vastly more complex architecture of circuits and sensors inside these devices, all at a scale nearly invisible to the eye. It’s taken us decades to develop and shrink down these microelectronics to where they are today, which is no small feat. Join us as we ride the ever-shrinking gadget wave from its early days to some of the nanoscopic creations at work today. [Image: IBM Research Zurich] Filed under: Robots , Science Comments

Facebook Messenger has its first game

Facebook recently revealed that it would open up its Messenger platform to third-party apps , and we’re now seeing how you’ll be gaming on it. Facebook told TechCrunch that Doodle Draw is the first “true game, ” for Messenger — until now, it’s only permitted GIFs, audio and the like. I gave it a whirl, and it’s basically a social version of “Pictionary.” It suggests a word, then you draw it on the screen and share it on Facebook or privately to friends on Messenger. From there, they try to fill in the blanks and guess what it is. In short, it’s a droll simple game, exactly suited for a chat tool like Messenger. As TechCrunch pointed out, however, there is one worrying aspect to it. You can earn points by getting friends to participate, which might convince some folks to spam their contacts. So far, Messenger — which now has some 600 million users — has been relatively free of ads. In contrast, most of us have been bugged on Facebook by someone trying feed their Candy Crush addiction. Facebook has put a lid on that as of late , so hopefully they’ll keep a close eye on Messenger spam as well. Filed under: Gaming , Internet , Facebook Comments Via: TechCrunch Source: Google Play

Microsoft’s Surface Hub pen display costs from $6,999 to $19,999

You’d be forgiven if you forgot what the Surface Hub is. After all, Microsoft announced it the same day as its futuristic HoloLens headset — arguably the more interesting of the two products. Even so, though, the Hub is a compelling device in its own right: a big pen display designed for conference rooms, making it easier for employees to brainstorm, even if some people are tuning in remotely. We took one for a brief spin back in January, but at the time it was unclear when it would be available or how much it would cost. Today, Microsoft clarified that the 4K, 84-inch version we tried will cost $19, 999 and go on sale in July, right around the time Windows 10 comes out . In addition, there will be a smaller, 55-inch version available for a much lower price of $6, 999. (For the money, you get 1080p resolution on that one, which is just fine considering how relatively small the screen is.) Both should ship in early September. We know, we know: That sounds like a lot of money for what appears to just be a display. But keep in mind that the Surface Hub is actually a fully functioning Windows 10 PC, capable of running any app that would run on any other Windows machine. Also, Microsoft claims the price is competitive compared to traditional video-teleconference systems (the company estimates, for instance, that outfitting a room for 8 to 12 people would otherwise cost upwards of $38, 000, nearly twice the price of the 84-inch model). If nothing else, the Hub will be easier to use. Without logging into it, you can just walk up to the screen and start writing. The display comes with two pressure-sensitive pens, each of which attach magnetically to the side of the Hub and charge there, too. And because the display supports 100 simultaneous touch points, you can have multiple people writing at once, or doing things like holding and dragging elements across the screen. In our time with it, both at the launch event and a recent behind-closed-doors meeting, everything from writing to pinch-to-zoom felt smooth and controlled on the display. We’re also fans of the display’s matte, slightly textured finish: It doesn’t feel slippery like other touchscreens, and it makes writing feel a little more natural as well. Throughout, too, you can loop in remote coworkers via a built-in Skype app, as well as use any Miracast-enabled device (say, an Android phone or tablet) to wirelessly mirror the presentation. From there, you can “write back” notes from the Hub to these various devices, and anyone tuning in remotely will see the notes drawn in real-time, as if they were there in person. When you’re finished with your meeting, you can press an “I’m done” button, have the device email you the notes, at which point it’ll wipe itself before someone else uses the conference room. Can your current video-teleconference setup do that ? For the most part, it’ll be corporate IT departments buying the Hub, and luckily for them, they can buy it through the same channels as, say, the Surface Pro. (Microsoft says it was important that businesses be able to purchase the Hub the same way they would traditional A/V gear.) Even if you’re just a regular consumer, though, you might get your chance to play with the Hub after all: It will eventually be on display in Microsoft Stores, meaning anyone who walks in will be able to have some playtime.

A drop of blood reveals every disease you’ve ever had

This stock image is just for illustration, you do not need this much blood to take the new test. Every disease that you’ve ever encountered is cataloged within your DNA, and now a team from the Howard Hughes Medical Institute has worked out how to access that data. It’s part of a project called VirScan that, it’s hoped, will revolutionize medical testing and help Doctors catch illnesses long before they manifest. Even better, is that it’s not even an expensive procedure, with each test slated to cost just $25 — well, at least before your hospital slaps on their own fee on top. The project has been led by Stephen Elledge, who says that Doctors normally treat viral infestions with a trial-and-error system of testing based on symptoms. By comparison, VirScan can just examine every nasty thing your body has come into contact with and center in on what’s causing the trouble. The technique could become critical in finding and solving conditions with a very long incubation time, like HIV and hepatitis C. As part of the research, the team also discovered that most people’s bodies deal with infections in a similar way, and that the system could help develop vaccines for previously un-treated conditions. Elledge also believes that the technology is going to help researchers investigate if there’s a link between viral infections and non-viral conditions like diabetes and multiple sclerosis. The good news doesn’t stop there, either, since it could also make medical research across borders significantly easier. With a VirScan device, scientists could easily compare and contrast the infection rates for various diseases across the globe.

Quick Charge 2.0 is coming to USB charging stations

Isn’t it annoying when some smartphones boast Quick Charge 2.0 but only come with a regular USB charger? Given the option, we’d rather spend the money on something more practical, like a multi-port USB charging station that supports Quick Charge. And yes, we managed to stumble upon one at Computex, courtesy of Hong Kong’s Magic-Pro. The Power Station Super 4 comes with — you guessed it — four USB ports, two of which can automatically switch to either 9V or 12V for faster charging on compatible devices , while the third port offers the common 5V/2.4A output, and the last one does 5V/3A as the company anticipates a new wave of tablets that can take the higher current. Better yet, the hub comes with a car charger and a Quick Charge 2.0-friendly micro-USB data cable, so not bad at all for a $65 package. Expect this to hit the markets at around the end of this month. For those who want a smaller USB station with ample power output, Magic-Pro’s Charging Station Cube comes in at just 50 x 50 x 41 mm, but still offers four ports: two with dedicated 2.4A each, and two with 1A each. This is due to launch in pink, white and blue later this month for about $35. Last but not least, we spotted this beast alongside the other minions on the table. Like its predecessor, the Power Station 10+ comes with 10 USB ports, but instead of delivering just 1A to each, you get a generous 2.4A even when all ports are occupied! Alas, there’s no price nor date just yet. Filed under: Peripherals Comments

High-yield yeast converts 97 percent of a plant to biofuel

The Department of Energy’s BioEnergy Science Center announced a major breakthrough in the biofuel field yesterday: a newly developed strain of yeast capable of producing more than three times the amount of fuel from plant matter as the current record holder. The Center has teamed with Mascoma LLC to develop the new strain, dubbed C5 FUEL. Existing biofuel yeast strains generally only convert about 30 percent of a plant’s sugars and cannot effectively convert tough xylose sugars. C5 however can ferment up to 97 percent of plant sugars into ethanol, including the xylose that other strains can’t break down. What’s more, it does all that in just 48 hours as opposed to the multiple days or weeks that other strains require. The BESC team presented its findings at the 31st International Fuel Ethanol Workshop in Minneapolis on Thursday morning. They hope that the discovery will help make ethanol-based biofuels more accessible to the consumer market. “Driving down the cost to develop, verify and consolidate bioprocessing was at the heart of the BESC effort when we began in 2007, and this achievement allows us to advance to the next challenge, ” BESC Director Paul Gilna said in a statement. “This accomplishment represents a clearly impactful example of how our partnering with industry can accelerate the translation of our research capabilities and findings into commercial products.” Up next, the BESC hopes to perform the same biochemical gymnastics with thermophilic bacteria , which would produce fuel directly from biomass in just one step.
