Scientists from the Universitat Autònoma de Barcelona designed a magnetic cloak that'll both shield an object from an outside magnetic field and prevent an internal one from leaking out. It's an antimagnet and it'll have various military and medical applications.
The antimagnet uses a superconducting material that blocks the internal magnetic field of an object and several dampening layers to block the effect of the superconductor on the external magnetic field. Sounds complicated, and it is, but it could save your life some day.
Take, for example, a person with a pacemaker who needs an MRI. The magnetic field of the MRI would damage the pacemaker and potentially harm the patient. Likewise, the pacemaker's metal would interfere with the MRI's magnetic field and throw off the machine's results. A magnetic cloak could potentially negate these effects and let patients with a pacemaker receive a successful MRI scan.
It would also work to protect military ships from mines that detonate when they detect a magnetic field. If the magnetic field is cloaked, then the mines can't detect it and there's no devastating explosion.
The cloaking technology is in the design stage and will move into production so it can be tested in the real world.
There's no need to get too worked up about it, but you may want to keep an eye on the sky for the next day or so, just in case. NASA says the odds of a person getting hit by a piece of space debris is 1 in 3,200.
A U.S. research satellite is expected to plummet back to Earth sometime tomorrow and although much of the bus-sized satellite will burn up upon re-entry into the Earth's atmosphere, about 26 significant-sized chunks are expected to remain.
"There is a lot of space junk out there and continually there are satellites and other pieces of space junk that are entering Earth's atmosphere," she says, adding that a piece of this size returns to Earth about once a year.
NASA's website states there have been no confirmed reports of injury or significant property damage due to falling satellites thus far. An Oklahoma woman was apparently hit on the shoulder by a small piece of a rocket in 1997, but was not hurt.
NASA says there are about 21,000 pieces of "orbital debris" - man-made objects in orbit which serve no useful purpose - that are larger than 10 centimetres (four inches). It estimates there are about 500,000 pieces of space junk sized between one and 10 centimetres (0.4 and four inches) and probably tens of millions that are smaller than one centimetre (0.4 inches).
Since the space program started, about one piece of space junk falls to Earth each day. NASA predicts the 26 pieces of space junk expected to hit the Earth from this satellite will have a combined weight of 532 kilograms (1,173 pounds), the largest of which is expected to weigh 158 kilograms (348 pounds).
"You might expect there to be some damage if (a piece) fell on some property. It would probably damage it significantly,"
Given that, it would be nice to know if one should stay inside tomorrow or not, but not only is it difficult to predict the time the satellite debris will land, it's pretty well impossible to pinpoint with any accuracy where it will land.
"If there was a trajectory that this hunk of metal was travelling through and it was unimpeded, then we would be able to predict very well (where it will land), but there are all sorts of influences it may experience," Edwards says, including wind.
NASA expects the chunks will all land within 800 kilometres (500 miles) of each other - it's just not quite sure where that 800-kilometre stretch will be. Even within about two hours of the expected re-entry time, the best it will be able to do is predict within about 12,000 kilometres (7,500 miles) of the landing point.
In other words, if you happen to get hit by a piece of the landing satellite, you are very, very unlucky indeed. This particular satellite was launched in 1991, but was decommissioned in 2005.
In-app purchases via iTunes have apparently been failing in a big way for the last ten hours and app creators who depend on this heavily taxed income are getting antsy. The problem may be connected to fake purchase receipts getting into the system. Whatever the cause, developers are "losing lots of sales" for apps that use receipt verification and is "threatening to more-or-less take down the entire IAP ecosystem." Seeing as Apple insists on this being the only route for in-app purchasing, they'd better fix it pretty darned quick.
UK-based treehuggers can bust out the internet high fives now. Merry ol' Swindon just got the British isles' first ever commercial hydrogen refueling station. Part of a collaborative effort between industrial gas company BOC (which built and maintains the pumps), the Forward Swindon economic initiative and Honda, owners can roll their clean energy machines into the automaker's manufacturing lot for a fill-up.
BOC's hoping the experience, which reportedly looks and functions much like a traditional gas station, will serve as an example of the private - public partnerships required to rollout infrastructure for alternative energy adoption. So, it's good news for the fuel cell-equipped handful of you cruising about Swindon town, or just passing through on a 'round the world tour.
Bionics are an amazing technology that most of us will hopefully never have to use. But being able to move a robot hand with your brain is incredibly cool, and Touch Bionics' new Virtu-LIMB lets you try a bionic hand without "installing" it.
Virtu-limb works with either the i-LIMB Ultra—the update to the really awesome i-LIMB—or with some custom software that renders the hand's actions in real time. It works by gathering the same myoelectric signals that the bionic limb would normally gather from a patient, but routing it through a computer instead of a surgically attached limb.
The test drive feature has a few uses beyond just being a cool toy for nerdboys playing Terminator. It's good for helping determine which muscles are best suited to sending the prostheses myoelectric signals and helping to train patients to control muscle signals. And it can also be used by prospective patients before having the limb added. It's absolutely a really great technology, but I'm just wondering how long until some intrepid nerd tries it out and decides to replace a fully functional hand. More here.
Remember that one-inch Chobi Cam One spotted in Japan earlier this year? Well, its tiny self has now reappeared on US shores, ready to be lost in a sofa or coat pocket near you. Unimaginatively titled "The World's Smallest Camera," it's priced at $99.95 and packs a petite, two megapixel autofocus sensor capable of recording VGA video. Resembling a Lego Man's DSLR, storage is done on a microSD card, though you're more likely to run out of battery juice than space -- the battery will give a maximum of 30 minutes use from one hour's charge. "The world's smallest" are words we hear a lot at Engadget, and we're inclined to agree with CNET that JTT's previous camera, the Chobi Cam, is actually smaller by volume. The Chobi Cam One arrived with extra detachable lenses, but there's no word yet on whether these add-ons will appear in Hammacher Sclemmer's online store -- not that we really want to be lugging around a whole bunch of tiny lenses with us. Get it here.
A Facebook employee accidentally spilled the beans on an upcoming "Listen With Your Friend" feature that could launch as part of Facebook's new Music service.
According to the now deleted tweet, when a friend is listening to a track, you'll be able to join them and listen to the same song at the same time. It'll be like sharing headphones over the Internet, but only better since it's on Facebook.
Every time we reboot our computers, that scrolling code takes us right back to the days of War Gamesand Tab. Bringing us into the 21st century, Microsoft has decided to ditch the old boot by beautifying the whole experience with a graphical menu. Windows 8 will replace the standard fugly BIOS system with a Unified Extensible Firmware Interface (UEFI) -- giving users a high resolution logo and a graphical menu to gaze upon while powering up their PC. Besides just looking better, the menu lets you boot to a different disc, OS or USB drive using pretty pictures and words as prompts. If you're into a little self-inflicted eye torture, you can always pull up the command prompt menu from nightmares past.
You might have noticed that Facebook changed last night. Inline photos are a little bigger, the top bar a little blockier, and a news ticker now rests in the upper-righthand corner for real-time updates.
This latest flurry of updates caps off a steady flow of tweaks over the past few weeks. You now subscribe to your friends' updates as you would an RSS feeds. You can subscribe to people you're not even friends with. You can organize friend groups by type (in Google+ fashion), not just for chat purposes. And you also have more on-the-fly control over who does and doesn't see your wall posts. All of these features come together to make Facebook feel different, even if it's fundamentally unchanged at its core.
Apple's next big media event will be held on October 4th, where freshly minted CEO Tim Cook is expected to unveil the iPhone 5. Sources close to the situation say Cook will be the main presenter at the event, with execs Phil Schiller, Scott Forstall and Eddy Cue playing supporting roles.
This would mark the first time that Cook has actually led an Apple event, adding an extra wrinkle of significance to an already highly anticipated occasion. The site's sources went on to say that the next-gen iPhone will be available for purchase "within a few weeks" of the announcement, though All Things Digital acknowledges that the exact date of its unveiling is still subject to change.
Researchers in Japan and Germany have converted energy from soundwaves into electromagnetic energy, trapping a magnetic "spin current" between metal layers. In the experiment, when sound waves are directed at an interface between the thin metal layer and magnetic material, electrical signals are generated at a pair of electrodes attached above. When the soundwaves reach the magnetic material, this creates a spin current that gets picked up by three layers of metal. This is where the exercise class-sounding reverse spin Hall effect kicks in, transforming it into an electrical voltage.
At the moment, the project is looking into materials that are able to eke out more voltage from the process -- perhaps a few years later screaming at our phones will give their batteries a boost?
Just over four months after the unique device hit Verizon stores, the Sony Ericsson Xperia Play 4G has now made it past AT&T's front door and onto shelves nationwide. The unique factor on this particular version of the "PlayStation Phone" is the inclusion of 14.4Mbps HSPA+ -- with enhanced backhaul, naturally -- and will be the first PlayStation-Certified smartphone on AT&T's network. At $50, the pricing is certainly competitive since it ships with Android 2.3.3, a 1GHz single-core CPU, Adreno 205 GPU, 4-inch 854 x 480 display, and seven pre-loaded games.
It's one of life's great mysteries: how much damage can bird poop falling at terminal velocity really do? Rhett Allain, Wired's resident physics guy, did us all a kindness and set his equations on this serious and pressing matter, originally raised by a Car Talk caller.
The answer? Maaaaybe, if it was an especially large avian dump and had some debris in it. But I'm nowhere near smart enough to know if he's right or not. Click through for the math and headache and general feeling of insignificance. More here.
Check out the gigantic volume of photos now stored in Facebook compared to Flickr, the Library of Congress and Instagram. I knew they were big, but I never imagined the difference could be so huge. 140 billion photos! It defies belief.
It's 10,000 times larger than the photo catalog in the Library of Congress! And Flickr, which I erroneously thought would be larger than anything else, is just a tiny fraction of Facebook.
Digital cameras are now ubiquitous – it is estimated that 2.5 billion people in the world today have a digital camera. If the average person snaps 150 photos this year that would be a staggering 375 billion photos. That might sound implausible but this year people will upload over 70 billion photos to Facebook, suggesting around 20% of all photos this year will end up there. Already Facebook's photo collection has a staggering 140 billion photos, that's over 10,000 times larger than the Library of Congress.
According to 1000memories, so far humanity has taken 3.5 trillion. Right now, "every 2 minutes today we snap as many photos as the whole of humanity took in the 1800s."
Maybe someday someone would do something incredibly useful with them, like monitoring the state of mind of the whole planet by analyzing the expressions and landscapes of all these photos.
When Neal Patwari and his team of researchers developed a wireless network capable of seeing through walls, everybody assumed they were simply looking to cultivate their Alastor Moody-like superpowers. Turns out, they had far more important things on their minds. Patwari and his colleagues at the University of Utah have now penned a new study in which they demonstrate how their motion detecting technology could be used to monitor breathing patterns, as well, potentially enabling doctors to keep closer track of patients with sleep apnea or babies susceptible to sudden infant death syndrome (SIDS). To do this, he reclined on a hospital bed and surrounded himself with 20 wireless transceivers operating at a frequency of 2.4GHz, as pictured above. He then timed his breathing at about 15 breaths per minute (the average rate for a resting adult), which he measured with his array of nodes and a carbon dioxide monitor. The engineer ultimately found that his system's algorithm could accurately measure respiration within 0.4 to 0.2 breaths per minute -- a relatively low error rate, since most monitors round off to the nearest full breath. He says this development could offer a non-invasive and low-cost alternative to the devices used in most hospitals, and hopes to implement his technology into at-home baby monitors, as well. He acknowledges, however, that it will likely take at least five years before any of that happens -- so don't hold your breath.
Three new names appear to have been confirmed for Facebook's upcoming music launch: Rhapsody, Deezer, and SoundCloud. All the evidence was floating around in each of the service's HTML. I suppose we're officially counting iTunes out, then?
Judging from the clandestine screenshot you see above, it most certainly seems like that's the case. From AT&T's internal system, listing the "iPhone 4s White" beneath a handful of already familiar Apple handsets. Could it be? Is Cupertino actually planning on bringing a white version of its next iPhone out at launch? Only time will tell.
Here you see Larry Page's public Google+ page. And that he hasn't updated it in a month. Now, granted, he could very well be having a Plus Party for his Circles in there, but given the recent drop in public activity... Not a good look.
Back in 2008, Ozmo Devices paired up with Intel to get its WiFi PAN (WiFi Personal Area Network) tech into low-power devices. Fast-forward to a few years later, tack on a new partnership with Targus and get ready for the first of those Bluetooth-less peripherals to hit the market. The company's new accessory teammate is planning to rollout a line of WiFi Laser mice that incorporate the OZMO2000 chip, with the first mouse to hit sometime this September. The unreleased AMW58US model will connect directly to your computer's WiFi receiver and packs a four-way scroll wheel, laser sensor and compatibility for Windows 7 -- batteries included. There's no pre-order page available at the moment, so you'll just have to sit tight and wait it out.
The latest version of Skype for Mac allows you to chat directly with your Facebook friends, hopefully bringing you a better user experience than other chat system. It also allows you to see your wall and your friends.
I wish this happened more often, because I'm tired of having to deal with so many ways to communicate with my friends and family. Imagine a world in which every single instant messaging, voice and visual communication system operated between each other, regardless of the company who owns the system. Or imagine the same in reverse: a world where you couldn't call someone's cellphone because they were in a different network. This is stupid.
