Sony's 185TB data tape puts your hard drive to shame
It's hard for magnetic data tapes to stand out from the crowd in an era when it's easy to load up on legions of hard drives. However, Sony might have managed that rare feat with nano-sized tape tech that stores much more than off-the-shelf hardware. By optimizing how it sputters argon ions on to film to create magnetic material, the company has produced "nano-grained" tape that's 74 times denser than what you see today; at 185TB per cartridge, it makes even a 5TB hard disk seem quaint. Sony's breakthrough won't come to your home PC, but it could prove a big help to supercomputers and your favorite internet services -- many of them need high-capacity tape storage just to keep up with demand.

Magnetically lifted graphite moves by laser, may lead to light-based maglev vehicles (video)
Magnetic levitation is central to the fastest trains we know today, but it's that dependence on electromagnets and rails that limits how and where it's used for transportation. Aoyama Gakuin University has a unique alternative: changing the material properties themselves. By floating graphite over a bed of circular magnets, taking advantage of its tendency to generate an opposing magnetic field, researchers can move the graphite just by blasting its edge with a laser. The heat skews the magnetic behavior of that area enough to unbalance the graphite, either in a specific direction or a spin. The research team believes it could lead to maglev transportation or even energy converting turbines that are steered solely by light, with no contact or outside guides: maglev vehicle pilots could have much more control over where they go. Getting to that point will require a much larger scale, but successful development could give technology a very literal lift.
IndoorAtlas uses disturbances in the (geomagnetic) force to map interiors, plot a path to aisle 3 (video)
Interior navigation is only just coming into its own, but IndoorAtlas has developed a technology that could make it just as natural as breathing -- or at least, firing up a smartphone's mapping software. Developed by a team at Finland's University of Oulu, the method relies on identifying the unique geomagnetic field of every location on Earth to get positioning through a mobile device. It's not just accurate, to less than 6.6 feet, but can work without help from wireless signals and at depths that would scare off mere mortal technologies: IndoorAtlas has already conducted tests in a mine 4,593 feet deep. Geomagnetic location-finding is already available through an Android API, with hints of more platforms in the future. It will still need some tender loving care from app developers before we're using our smartphones to navigate through the grocery store as well as IndoorAtlas does in a video after the break.
Old reel-to-reel tape played back with Square reader on iPod touch
At first glance, you wouldn't think a Square reader could substitute as a reel-to-reel player, but it does and Evan Long has a video to prove it. Before you start calling shenanigans, remember that the Square reader is nothing but a magnetic head designed to read the magnetic strip of a credit card. As Long shows, it's not too far of a stretch to get it to read a magnetic tape. Long details the process in a blog post and shows how he cracked open the Square reader, bent the holder to fit the reel tape and connected it to the iPod Touch. This particular reader is likely an older version which sends its data in an unencrypted format. Long then reads this data and plays it back with a custom playback app (available on github). You can see Long's hack in action in the YouTube video below and read more about it on his website.
Apple snags a patent for the Smart Cover's magnetic know-how
No, it doesn't cover the totality of the Smart Cover itself (or any case that folds into a triangle), but Apple has now managed to obtain a patent for one of the accessory's key bits of functionality. First filed in July of 2011 and published by the USPTO today, the patent described as an "accessory device with magnetic attachment" details how magnets can be used in a particular manner to attach a cover to a device (like an iPad) and secure it in place, yet still allow it to be easily released. Again, that doesn't cover all cases that use magnets -- just magnets used in this very specific way. Hit the source link below for all the details in patent-speak.
Magnetic retainer lets you operate machinery with your tongue, gives linguistics new meaning
Many people with debilitating conditions rely on sip and puff technology to get around, which is relatively lo-fi by some standards. Now, a special retainer with magnetic sensors could bring mobility into the smartphone age. Developed at Georgia Tech, the Tongue Drive System uses a magnetic piercing to track lingual gestures. The sensors then transmit data to an iOS app that translates it to on-screen or a joystick movement. Earlier versions used a headset, but the prototype revealed at the International Solid State Circuits Conference in San Francisco, is hoped to be more comfortable and discreet. The system is currently being trialled by 11 participants with high-level spinal-cord injuries, with larger trials planned.
Magnus magnetic stand has a hold on your iPad 2
Sometimes the most simple accessories can be the most effective. When I received a tiny box from Ten One Design claiming to hold a stand that would support an iPad 2 in an upright position, I scoffed. But it turns out that the Magnus magnetic stand (US$49.95) really does work. The Magnus is a tiny sculpted piece of aluminum with a very powerful magnetic strip at the bottom. When you place an iPad 2 onto it in the designated landscape orientation (with the home button on the right side), the Magnus and iPad click together. Held in the magnetic clutch of the Magnus, the iPad is nicely balanced and stays securely perched. This is one of the smallest iPad stands I've reviewed so far ... and I've reviewed a lot of 'em. For anyone who wants a stand that will hold an iPad in landscape orientation and is virtually invisible at the same time, the Magnus is your product. On the other hand, if you like your iPad in the full, upright position (portrait) look elsewhere. For movie viewing or using the iPad with a Bluetooth keyboard, the Magnus is perfect. At 4.6 ounces, the Magnus won't load down your favorite iPad bag while in transit. And dang, it just looks good. There's not much more to say than that, so I'll just let you take a look at the gallery for more views of what could become your favorite slab of aluminum ... other than your iPad 2. %Gallery-147817%
Apple patent looks to create 'secure magnets' to unlock your device
It's an Apple patent application: please be aware this is unlikely to wind up in your next device, please fasten seat belts and fix your tray table in the fixed and upright position. Inside the bezel of your iDevice or Mac is a magnet that operates a switch -- that will only be activated when a "correlated" magnet inside a key-fob makes contact. That's the thinking behind Cupertino's newest patent application, attempting to turn magnets into a way of keeping your stuff secure. An example listed in the patent is using a stylus with specially encoded magnets to securely unlock an iPad, which we attribute to a zealous patent attorney and not a reversal of the "they blew it" rule. It may sound ridiculous when you first consider it, but given the magnetic-activation of the iPad 2's smart cover, it's not as outlandish as you believe. Still, we'll believe it if we see it in a couple of years.
Researcher brings modified Touchpad into the MRI room, breakthrough ensues
Yes, the Touchpad is officially dead, but that hasn't stopped Stanford researcher Andrew B. Holbrook from using HP's tablet in a somewhat unexpected setting: the MRI lab. Holbrook, it turns out, has been developing a new, webOS-based system that could make it a lot easier for doctors to conduct interventional MRI procedures. Unlike its diagnostic counterpart, this brand of MRI can only operate within highly magnetic fields, thereby posing a threat to many electronic devices. Holbrook, however, may have found a way around this barrier, thanks to a modified Touchpad. With the help of HP engineers, the researcher stripped his tablet of metallic components, including its speakers and vibration motor, resulting in what the manufacturer calls a "minimally metallic device that could be used almost anywhere within the magnet room." With his Touchpad primed and loaded with apps for data manipulation, Holbrook went on to successfully integrate the device within an MRI system. He also developed a series of apps that allow technicians to monitor and manipulate an MRI procedure on their devices, regardless of whether they're in the magnet room itself, or outside. Holbrook says he's already started applying the same approach to webOS phones, in the hopes of providing doctors and researchers with an even more compact way to keep track of their patients. For more details on the system and future developments, check out the source link below. [Thanks, Mina]
Lyneborg bot carves models of magnetic fields, dares the future to have a look (video)
If you're going to create a robot that carves something, have it carve models of an invisible field. This is what Frits Lyneborg, creator of the Yellow Drum Machine, has done with a new homemade bot that uses a combination of motors, pulleys, small drills, makerbeams and magnetic sensors. The end result is a robot that, when combined with the interpretative software, can literally read a magnetic field and move the robot's components to cut an accurate model from a crumbly-yet-strong material known as 'Oasis Brick.' You can witness the magic yourself in a video after the break, and if you've any advice for making it better, drop Frits a line there in the via link.
Nuclear clocks could be 60x as accurate as atomic counterparts, less prone to errors
For years, atomic clocks have been considered the most accurate devices for tracking the slow march towards obsolescence, a subatomic particle vibrating a given number of times per second with relatively few issues. Now the reliability crown might be passed to the nuclear clock, which in addition to sounding gnarly, could prove to be less susceptible to errors from outside stimuli. It goes like this: although an atomic clock will measure a certain number of vibrations per second, external forces such as ambient electric and magnetic fields affect the electrons used in atomic clocks, causing mishaps. The particles used in nuclear clocks that are measured for vibrations -- and thus timekeeping -- can be excited with a relatively low-energy ultraviolet light, allowing for fewer variations from the aforementioned fields. To wit, Corey Campbell and colleagues at the Georgia Institute of Technology in Atlanta have devised a scheme that uses lasers to carefully control the spatial orientation of the electron orbits in atoms. A nuclear clock containing a thorium nucleus controlled in this way would drift by just one second in 200 billion years, the team claims. Before nuclear clocks become a reality, researchers must identify the precise frequency of light needed to excite thorium nuclei; but this is what grad students are for, right?

FingerFlux system uses magnets to add tactile feedback to touchscreens
We've seen a number of efforts that promise to make touchscreens more tactile, but none quite like this so-called FingerFlux system developed by a team of researchers from Germany's Aachen University. Its hook is a layer of magnets that lie beneath the touchscreen and react to a simple thimble that the user must wear. While that particular accoutrement could be considered a slight drawback, it does open up a number of interesting possibilities -- including the ability to draw your finger towards an item on the screen, and "lock" it in a certain area. What's particularly key, however, is that you're also able to feel a bit of feedback before you even touch the screen -- as opposed to other entirely screen-based options -- which could could let you operate something like media player controls without actually looking at your phone. Of course, it's all still a long ways from being shrunk down to phone-size, but the researchers do have a working prototype in a table-top device. Check it out in the video after the break.
Smart Cover can unlock password-protected iPads running iOS 5 (video)
Psst. Hey, do you carry a spare Smart Cover around with you? Well, if you're an unscrupulous sort, you can actually use it to bypass the lock screen of any iPad running iOS 5. This multi-step security hole will let you browse whatever's running behind the passcode screen, whether that's email, apps or the homescreen. To take advantage of the flaw, hold down the power button on the locked device until the power off slider appears, then whip the Smart Cover on, open and tap cancel. Fortunately for iPad owners, the rest of the tablet remains locked-down, but the main problem here is any sensitive information left on-screen. If you unlock the tablet to the main screen, you won't be able to open new apps, although anyone feeling particularly nefarious can apparently delete apps from that meticulously arranged home screen. See how it's done in the video after the break. [Thanks to everyone who sent this in]
Levitating superconductor floats within a magnetic field so you don't have to (video)
What happens when you douse a superconducting urinal cake with liquid nitrogen? We haven't given it too much thought, to be honest, though we're guessing it would look a lot like the "levitating" disc pictured above. Developed by researchers at Tel-Aviv University, this device is actually a superconductor hovering over a "supercooled" magnet. While locked within the magnetic field, it can rotate around a vertical axis, turn upside down or do laps around a track -- all thanks to a phenomenon that Tel-Aviv's physicists call "quantum trapping." We're not really sure what that entails, but we do know that the results are pretty incredible. Check them out for yourself, after the break. [Thanks to everyone who sent this in]
Speck SmartShell iPad 2 companion case with magnetic strip enhances the Smart Cover
Today's Smart Cover-compatible iPad 2 backplate, the SmartShell, is courtesy of Palo Alto-based Speck and has a neat trick up its sleeve. Coverage Like many of the other backplate-type cases, the SmartShell covers the back and edges well. It has good sized cut outs for the ports, mic, buttons, camera and speaker, as well as a cut out in the side to allow you to lift up the Smart Cover a little more easily. It has all the important things covered, but that opening in the side could be a potential vulnerability. Thickness and material The case is made of polycarbonate and is available in six different colors including clear and looks pretty good once on the iPad. The majority of the case is just 1.2mm thick, meaning it's one of the thinner polycarbonate offerings available. At the edges, where the case meets the front of the iPad the plastic gets thicker and creates a noticeable edge around the smooth tapering of the iPad 2. Unfortunately there are also some sharp edges to the case, which feels cheap and makes the iPad uncomfortable to hold. This might be a one-off with our clear review unit, but it appeared to be a lack of finishing during manufacture, which we haven't seen with other polycarbonate cases in this class. Features The SmartShell has a nifty trick up its sleeve that we haven't seen in other backshell cases and that's a magnetic metal strip on the back side of the case that holds the Smart Cover in place then folded around the back. This is the kind of thing Apple should have built into the iPad 2 itself, as it removes the annoying flop of the Smart Cover when it's open and works wonderfully in the SmartShell. %Gallery-134782% Verdict The Speck SmartShell has good coverage, is pretty thin and comes in a decent set of colors to match your Smart Cover. The magnetic strip on the back is great and improves the Smart Cover no end. It's a shame then that the clear polycarbonate isn't as well finished as we would have liked, and those sharp edges that make the iPad 2 uncomfortable to hold aren't what we're looking for. Your mileage may vary and indeed the "matte soft-touch" finish of the colored cases may be different. For the clear cases we hope this is a one-off production error, but the rest of our review unit seems perfect so we can only conclude that it's cheap manufacture is to blame. If you can get one out in a store and check the edges, or buy it from an online retailer with a solid return policy, then the Speck SmartShell is definitely worth a look and will set you back around US$25-35 plus shipping.
Magnetic Cello almost makes it cool to play the cello (video)
Say hello to the Magnetic Cello, the perfect companion to your magnetic drum kit. Crafted by college student David Levi (AKA "Magnetovore"), the instrument vaguely represents a traditional cello in structure, but the similarities pretty much end right there. To play it, for example, musicians use not a horsehair bow, but a magnetic rod that produces a voltage within an attached coil (the "bridge," in this case). Its "strings," meanwhile, consist of resistive ribbons connected to a voltage-controlled oscillator, allowing users to manipulate volume with the magnet-bow. The result sounds surprisingly cello-like, though Levi says he's still tinkering with its tone and playability. Waltz past the break to see the beast in action for yourself, or find more details in Levi's provisional patent application at the link below.
Sinch takes aim at headphone tangles, we go hands-on
The Sinch is not much to look at, we'll give you that, but it is rather an interesting little thing. Intended to keep your headphone cable a little more tidy, it's just a couple of slender magnets encased in a rubber band with a hole punched on one end. It's a remarkably simple design, and a surprisingly effective one, too. We got a chance to wrap our cables around one, so read on for some quick impressions. %Gallery-133151%
New phase-changing alloy turns waste heat into green energy, exhibits spontaneous magnetism (video)
Looks like harvesting waste heat is all the rage in 2011. Yet another team of researchers -- this time at the University of Minnesota -- has found a way to harness energy from our hot castoffs. The group has apparently created a brand spanking new alloy that spontaneously creates energy when its temperature is raised by a small amount. Future uses for the material, known as Ni45Co5Mn40Sn10, include charging a hybrid car's battery with the help of waste heat from its exhaust. So what's the trick? Well, this wonder material is a phase changer, meaning it can go from non-magnetic to magnetic in moments, when the temperature rises. When that happens, the alloy absorbs heat, and bam! You've got electricity. The team is also collaborating with chemical engineers to create a thin film version of the material that could be used to convert waste heat from computers. If phase changing gets you all hot and bothered, check out a video demonstration of the alloy's sudden magnetism after the break.
Antimatter gets trapped for 15 minutes by CERN scientists, escapes unharmed
Antimatter particles are elusive little critters that tend to disappear moments after being spotted. Unless, it turns out, you trap them in a "magnetic bottle" and turn the temperature right down to almost absolute zero. CERN scientists have now used this technique to hold 300 antihydrogen particles for up to 1,000 seconds, relaxing them into their ground (stationary) state to make them easier to study. This opens the way for further research later in the year, when captured particles will be prodded with lasers and microwaves to see if they obey the same laws of physics that govern everything else in our universe. After all this effort, we're quietly hoping they don't. [Thanks, Howard]
Maglus iPad stylus rendered for Fund.it, an Irish Kickstarter-like project
Considering the iPad 2 works just fine with just a finger for most people, I wouldn't have thought there was much of a mass-market for a capacitive stylus for use on the 9.7" tablet. But that hasn't stopped people trying, including a new Irish Kickstarter-like project called The Maglus. The Maglus, as the name might suggest, is a magnetic capacitive stylus that will mimic the touch of a finger on the iPad's screen. It tucks neatly out the way when not in use by attaching to the Smart Cover or the body of the iPad 2. Having reached €2,939.00 (US$4,350) of the target €15000 ($22,195), the team behind the €24.99 Maglus has released a couple of new renders of the near final product (as seen above). You can view a video of a prototype below. If you're interested in getting your hands on one -- perhaps you're an artist, illustrator or someone who needs the precision of a pen on the iPad -- then head over to the Maglus Fund.it page. You can pledge €15 or more to secure yourself one of the magnetic styluses, but hurry -- the offer is only open to the first 2000 pledgers. [via RazorianFly]
