CERN update on its search for Higgs boson starts at 3AM ET (video)
The cat would appear to be out of the bag, but if you must find out about the status of the Higgs boson search ASAP, check the video stream (embedded after the break) as CERN scientists reveal whatever it is they've found. The webcast is scheduled to kick off at 2:55AM ET, as a prelude to this year's ICHEP particle physics conference in Melbourne. Whenever the announcement comes we'll be sure to let you know, check the links below for more information. Update: So yeah, they've found a new particle "consistent with Higgs boson," check out all the details here.
Now NASA's thinking with portals (video)
Looks like playing games and watching sci-fi flicks didn't do the University of Iowa's Jack Scudder any harm. The NASA-funded researcher has been studying elusive magnetic portals connecting the Earth and Sun, and now he's figured out how to find them. The portals, also known as X-points in Scudder-speak, are born from the mingling of Earth's magnetic field with incoming solar winds. These astral connections create flux transfer events (we've got Doc Brown's attention) -- high-energy particle flows responsible for, among other things, the eerie twinkling of the polar auroras. Off the back of Scudder's data wizardry, NASA's planning the 2014 Magnetospheric Multiscale Mission (MMS), sending four craft into the void to observe the portals. Each spacebot is capable of locating them, and when one is found, inviting the others 'round for a study date. Taking a leaf from Scudder's book, Engadget researchers have tracked down a NASA video detailing the mission, located beyond the fold for your convenience.
Spanish researchers to train FIFA referees on calling plays with stereoscopic 3D, won't help catch dives
Spain might be on Cloud Nine after clinching victory in UEFA's Euro 2012, but a team at the Universidad Carlos III de Madrid isn't resting easy. To help referees know when they should blow the whistle, researchers have recorded 500 simulated offside soccer (yes, football) plays in stereoscopic 3D to give refs a more immersive sense of what it's like to make the call on the pitch. The hope is to have FIFA more quickly and accurately stopping play without having to spend too much actual time on the grass. We don't yet know how many referees if any will be trained on the system by the 2014 World Cup, or if it will spread to other leagues -- what we do know is that no amount of extra immersion is needed to catch a theatrically fake injury.
Higgs boson just may, possibly, more or less be proven to exist by ATLAS and CMS teams
We had a false alarm over the possible discovery of the theory-unifying Higgs boson last year, but a bit of poking and prodding in subsequent months may well have given us much more definitive evidence of the elusive particle. According to some rare rumors emerging from Nature, both CERN's ATLAS and CMS detectors have seen particle decay signals suggesting the existence of Higgs to within a 4.5 to 5 sigma level of proof -- in other words, very nearly concrete evidence. That's not quite the 5-plus needed to settle the matter, but it's to a much higher level of certainty than before. As if to add fuel to the fire, ScienceNews even located a briefly posted, CERN-made video (sadly, since pulled) saying bluntly that the CMS team had "observed a new particle." Whether or not there's any substance is another matter. Nature hears that scientists are supposedly still working out what to say at an event on Wednesday, while CERN has made the slightly odd claim to ScienceNews that the yanked video is just one of several pre-recorded segments made to cover possible outcomes -- you know, in that "Dewey defeats Truman" sort of way. Unless the scientists have to go back to the drawing board, though, the focus from now on may be more on learning how Higgs behaves than its very existence. Any significant truth could see researchers proving the validity of the standard model of physics just as we're firing up our Independence Day barbecues.
Researchers create 'rubber-band electronics' material, capable of stretching up to 200 percent (video)
One of the major issues with embedded medical devices is the lack of flexibility in existing electronics. Fortunately, researchers at the McCormick School of Engineering at Northwestern University have developed a new material that can create electronic components capable of stretching to 200 percent of their original size. One of the major obstacles was how stretchable electronics with solid metal parts suffered substantial drops in conductivity but this solution involves a pliable three-dimensional structure made from polymers with 'pores'. These are then filled with liquid metal which can adjust to substantial size and shape changes, all while maintaining strong conductivity. We've embedded a very brief video of the new stretchable material going up against existing solutions -- it's right after the break.
Researchers use 3D printer, sugar, to create a fake artery network for lab-grown tissue
Printing a chocolate heart is easy enough, but how about an actual organ? There are folks working on it, but it turns out those veins of yours aren't exactly a breeze to replicate. Researchers at the University of Pennsylvania and MIT may have found a semi-sweet solution -- dissolving a sugar lattice in a batch of living Jell-O. The research team uses a RepRap 3D printer and a custom extruder head to print a filament network composed of sucrose, glucose and dextran which is later encased in a bio-gel containing living cells. Once the confectionery paths are dissolved, they leave a network of artery-like channels in their void. Tissue living in the gel can then receive oxygen and nutrients through the hollow pipes. The research has been promising so far, and has increased the number of functional liver cells the team has been able to maintain in artificial tissues. These results suggest the technique could have future research possibilities in developing lab-grown organs. MIT Professor Sangeeta Bhatia, who helped conduct the effort, hopes to push the group's work further. "More work will be needed to learn how to directly connect these types of vascular networks to natural blood vessels while at the same time investigating fundamental interactions between the liver cells and the patterned vasculature. It's an exciting future ahead." Scientists at other labs could also get their mitts on the sweet templates since they're stable enough to endure shipping. Head past the break for a video of the innard infrastructure.
Fujitsu, NICT create indoor navigation for the blind using ultrawideband, Android phones, kind hearts
There's no shortage of navigation outdoors, and even a little bit of help indoors, but there's been precious little aid for the blind indoors -- leaving them little choice but to move cautiously or get outside help. Fujitsu and Japan's NICT have crafted a system that gives the sightless a greater level of autonomy inside through ultrawideband-based impulse radio. A grid of UWB radios positioned around a room gauge the distances between each other and transmit the data to a PC, which then talks to the traveler's Android phone. The device then gives spoken directions based on a 12-o'clock system and far subtler distances than GPS can manage: the positioning is accurate to within a foot. While the indoors navigation is only just getting a demo this week, it's already being refined to detect objects in the room as well as to help even the fully sighted. If Fujitsu and NICT have their way, buildings ranging from hospitals to malls will have their own turn-by-turn navigation. For some, the freedom of movement could be a life-changer.
New fuel cell keeps on going even once the fuel's dried up
Vanadium oxide seems to be the go-to guy in power storage right now. A new solid-oxide fuel cell -- developed at Harvard's School of Engineering and Applied Sciences -- that can also store energy like a battery, also uses the stuff. In the new cell, by adding a VOx layer it allows the SOFC to both generate and store power. Example applications would be situations where a lightweight power source is required, with the potential to provide reserve juice should the main fuel source run out. The team who developed the cell usually work with platinum-based SOFCs, but they can't store a charge for much more than 15 seconds. By adding the VOx, this proof of concept extended that by 14 times, with the potential for more lifespan with further development. Especially handy if you're always running out of sugar.
University of Tokyo builds a soap bubble 3D screen, guarantees your display stays squeaky clean (video)
There are waterfall screens, but what if you'd like your display to be a little more... pristine? Researchers at the University of Tokyo have developed a display that hits soap bubbles with ultrasonic sound to change the surface. At a minimum, it can change how light glances off the soap film to produce the image. It gets truly creative when taking advantage of the soap's properties: a single screen is enough to alter the texture of a 2D image, and multiple screens in tandem can create what amounts to a slightly sticky hologram. As the soap is made out of sturdy colloids rather than the easily-burst mixture we all knew as kids, users won't have to worry about an overly touch-happy colleague popping a business presentation. There's a video preview of the technology after the jump; we're promised a closer look at the technology during the SIGGRAPH expo in August, but we don't yet know how many years it will take to find sudsy screens in the wild.
New system lets you type with your brain using MRIs
This isn't mind reading, per say. Instead Bettina Sorger, Joel Reithler, Brigitte Dahmen and Rainer Goebel at Universiteit Maastricht have figured out a way to monitor the flow of blood in the brain and associate the images captured using an MRI with the letters of the alphabet. The whole system takes about an hour to learn and configure for each individual. Trials focused on healthy individuals, but clearly its the paralyzed and people suffering from diseases like ALS that have the most to gain. Sorger hopes to enable "locked-in" patients to finally be able to communicate with the outside world by thinking out letter at a time. Obviously, patients aren't going to be able to install an MRI in their homes, much less lug one around with them. The data collected could be used to finely tailor less accurate but more portable systems for patients that monitor electrical or light signals. If you're interested in the real nitty-gritty you can check out the complete research paper at the source link.
Researchers partially automate CPU core design, aim to fast track new PC processor production
Tired of the year wait (or more) in between new silicon architecture offerings from Chipzilla and AMD? Well, if some Wolfpack researchers have anything to say about it, we'll measure that wait in months thanks to a new CPU core design tool that automates part of the process. Creating a new CPU core is, on a high level, a two step procedure. First, the architectural specification is created, which sets the core's dimensions and arranges its components. That requires some heavy intellectual lifting, and involves teams of engineers to complete. Previously, similar manpower was needed for the second step, where the architecture spec is translated into an implementation design that can be fabricated in a factory. No longer. The aforementioned NC State boffins have come up with a tool that allows engineers to input their architecture specification, and it generates an implementation design that's used to draw up manufacturing blueprints. The result? Considerable time and manpower savings in creating newly designed CPU cores, which means that all those leaked roadmaps we're so fond of could be in serious need of revision sometime soon.
CCNY, UC Berkeley develop lasers that could rewrite quantum chips, spin those atoms right round
Computers are normally limited by the fixed nature of their chipsets: once the silicon is out of the factory, its capabilities are forever locked in. The City College of New York and University of California Berkeley have jointly developed a technique that could break chips free of these prisons and speed along quantum computing. They found that hitting gallium arsenide with a laser light pattern aligns the spins of the atoms under the rays, creating a spintronic circuit that can re-map at a moment's notice. The laser could be vital to quantum computers, which can depend heavily or exclusively on spintronics to work: a simple shine could get electrons storing a much wider range of numbers and consequently handling many more calculations at once. Research is only just now becoming public, however; even though gallium arsenide is common in modern technology, we'll need to be patient before we find quantum PCs at the local big-box retail chain. Despite this, we could still be looking at an early step in a shift from computers with many single-purpose components to the abstracted, all-powerful quantum machines we've held in our science fiction dreams.
Google simulates the human brain with 1000 machines, 16000 cores and a love of cats
Don't tell Google, but its latest X lab project is something performed by the great internet public every day. For free. Mountain View's secret lab stitched together 1,000 computers totaling 16,000 cores to form a neural network with over 1 billion connections, and sent it to YouTube looking for cats. Unlike the popular human time-sink, this was all in the name of science: specifically, simulating the human brain. The neural machine was presented with 10 million images taken from random videos, and went about teaching itself what our feline friends look like. Unlike similar experiments, where some manual guidance and supervision is involved, Google's pseudo-brain was given no such assistance. It wasn't just about cats, of course -- the broader aim was to see whether computers can learn face detection without labeled images. After studying the large set of image-data, the cluster revealed that indeed it could, in addition to being able to develop concepts for human body parts and -- of course -- cats. Overall, there was 15.8 percent accuracy in recognizing 20,000 object categories, which the researchers claim is a 70 percent jump over previous studies. Full details of the hows and whys will be presented at a forthcoming conference in Edinburgh.
New wireless transmission tech hits 2.56Tbps, leaves WiFi feeling inadequate
Stoked about the gigabit speeds your new 802.11ac WiFi router is pumping out? One group of scientists hailing from NASA's Jet Propulsion Laboratory and universities in the US, Israel and China isn't so impressed, having generated a wireless signal clocking in at 2.56Tbps. Proof of the feat was published in Nature Photonics, which details their use of orbital angular momentum (OAM) to make the magic happen. Current wireless protocols alter the spin angular momentum (SAM) of radio waves to hold info, and by combining both methods the team was able to pack eight data steams into a single signal, resulting in the mouth-watering number noted above. The best part is, applying different levels of OAM twist to SAM-based transmissions theoretically allows an infinite number of streams per signal, meaning seriously increased bandwidth without the need for additional frequency. So far the wireless tests have only been conducted over a measly 1m, but the scientists reckon it'll work at distances up to 1km and that the concept could also be used to boost speeds in existing fiber-optic cables. As with many scientific advances, it's unlikely hardware capable of such speeds will be available any time soon, so 802.11ac will have to suffice... for now.
Chinese astronauts go hands-on, manually dock with orbiting module
Looks like China continues to add to its space cred after recently joining the rarefied ranks of countries that have successfully docked craft in the final frontier. Fresh off from the recent joining of the Shenzhou 9 capsule with the Tiangong 1 orbiting module, China's three astronauts have now replicated the feat manually, according to the Washington Post . For the uninitiated, the first docking was done via remote control from the ground. The mission has had plenty of firsts for China so far, including the country's first female astronaut. It also serves as a precursor to establishing China's first permanent space station, a 60-ton facility that's about a sixth of the size of the International Space Station but is slightly bigger than NASA's old Skylab.

Phase change memory breakthrough could lead to gigahertz-plus data transfers, make SSDs seem pokey
Often considered the eventual successor to flash, phase change memory has had a tough time getting to the point where it would truly take over; when it takes longer to write data than conventional RAM, there's clearly a roadblock. The University of Cambridge has the potential cure through a constant-power trick that primes the needed hybrid of germanium, antimony and tellurium so that it crystalizes much faster, committing data to memory at an equally speedy rate. Sending a steady, weak electric field through the substance lets a write operation go through in just 500 picoseconds; that's 10 times faster than an earlier development without the antimony or continuous power. Researchers think it could lead to permanent storage that runs at refresh rates of a gigahertz or more. In other words, the kinds of responsiveness that would make solid-state drives break out in a sweat. Any practical use is still some distance off, although avid phase change memory producers like Micron are no doubt champing at the bit for any upgrade they can get.
Google's Turing doodle celebrates his genius, reminds us how dumb we are (video)
This week sees many corners of the globe celebrating the 100th anniversary of the birth of Alan Turing. A man whose contribution to the worlds of tech and gadgets is immeasurable -- a sentiment not lost on Google. Today, geeks and norms worldwide will be waking up to possibly the most complex doodle to date. Can you set the machine and spell out "Google"? If you can, you'll be sent off to lots more information about the man himself. This isn't the only thing Mountain View's done to keep his legacy alive, having previously helped Bletchley Park raise funds to purchase (and display) Turing's papers, and more recently helping curators at London's Science Museum with its Codebreaker - Alan Turing's Life and Legacy exhibition. If you haven't already, head to Google.com and pop your logic hat on, and if you get stuck, head past the break for a helpful video.
Negative radiation pressure in light could make some tractor beams real, we're already sucked in
Developing a real, working tractor beam has regularly been an exercise in frustration: it often relies on brute force attempts to induce a magnetic link or an air pressure gap, either of which falls a bit short of science fiction-level elegance. The Technion-Israel Institute of Technology's Mordechai Segev has a theory that would use the subtler (though not entirely movie-like) concept of negative radiation pressure in light to move objects. By using materials that have a negative refraction index, where the light photons and their overall wave shape move in opposite directions, Segev wants to create a sweet spot where negative radiation pressure exists and an object caught in the middle can be pushed around. His early approach would use extremely thin crystals stacked in layers to manipulate the refraction. As it's theorized, the technology won't be pulling in the Millennium Falcon anytime soon -- the millimeters-wide layer intervals dictate the size of what can be pulled. Nonetheless, even the surgery-level tractor beams that Segev hopes will ultimately stem from upcoming tests would bring us much closer to the future that we've always wanted.
All-carbon solar cell draws power from near-infrared light, our energy future is literally that much brighter
What's this orange-like patch, you ask? It's a layer of carbon nanotubes on silicon, and it might just be instrumental to getting a lot more power out of solar cells than we're used to. Current solar power largely ignores near-infrared light and wastes about 40 percent of the potential energy it could harness. A mix of carbon nanotubes and buckyballs developed by MIT, however, can catch that near-infrared light without degrading like earlier composites. The all-carbon formula doesn't need to be thickly spread to do its work, and it simply lets visible light through -- it could layer on top of a traditional solar cell to catch many more of the sun's rays. Most of the challenge, as we often see for solar cells, is just a matter of improving the energy conversion rate. Provided the researchers can keep refining the project, we could be looking at a big leap in solar power efficiency with very little extra footprint, something we'd very much like to see on the roof of a hybrid sedan.
MIT thaumaturges work to turn any windowed room into a camera obscura
Those interested in criminology, forensics or the basics of voyeurism probably have a decent grasp on what a camera obscura is. For everyone else in the audience, allow us to explain. Used since way before your birth, these chambers are designed with an optical device that projects an image of its surroundings on a screen; you just need a room with a hole in one side, which allows a fine amount of light to pass through. If you've ever watched [insert crime drama here], you've probably seen those magical investigators take a blurred shot of a room wall, zoom it in and somehow draw conclusions about the origins of life. Now, MIT's own Antonio Torralba and William Freeman have developed a method that can "transform the entire setting into a pinhole camera." In other words, any room with a window can be repurposed for forensics. On that note, you should probably consider moving your... operations center to a windowless bunker, STAT.
