Scientists unveil image of quantum entanglement for the first time ever
For the first time ever, physicists have captured an image of quantum entanglement. In a paper published in the journal of Scientific Advances, scientists from the University of Glasglow shared the first known image of a Bell entanglement. The photo depicts two photons interacting and sharing physical states for a brief instant -- an event that occurs regardless of the actual distance between the particles.
'Unprecedented' 3D magnetic interactions could change computing
The field of spintronics, or spin electronics, uses an electron's spin and its magnetic movement to encode instructions and other data. It's sometimes seen as an alternative to electronics, which relies on the electron's charge to encode data. While spintronics has the potential to increase data processing speeds, boost storage capacity and offer increased data resilience, it's been limited because physicists could only move the electrons -- or tiny magnetic particles -- around a single atomic layer. Now, researchers have found a way to move information from magnets in one layer to magnets in another. They hope the discovery will lead to new possibilities for data storage and computing.
Digital music may not have saved the environment after all
Logic would suggest that music downloads and streaming are good for the environment. You're not buying physical copies, right? Not so fast -- there's a chance things could be worse. Researchers have published a study suggesting that greenhouse gas emissions are higher now than they were when physical media was all the rage. While going digital has reduced the amount of plastic, the combination of extra power demands and the sheer popularity of music (you can listen to virtually anything for $10 per month, after all) may have offset other gains. Where vinyl produced 346 million pounds of greenhouse gasses at its height in 1977, downloads and streaming are estimated to pump out 441 million to 772 million pounds.
Researchers digitally reconstruct the face of a legendary Scottish king
Robert the Bruce, a medieval warrior and hero-king of the Scottish people, is something of an enigma. While his exploits in battle against both domestic rivals and British occupiers have been well-documented, descriptions of his physical appearance have long been lost to history. But thanks to a collaborative effort between researchers at the University of Glasgow and Liverpool John Moores University (LJMU), we may finally know what he looked like.
Research shows eye-reflections in photos could be used to identify criminals
Did you ever watch CSI's tech boffins zoom into a photo, grab the reflection in someone's eye, and through processing magic generate a full facial image of the wanted criminal? If, like us, you rolled your eyes at the program's "Hollywood" technology, then maybe you did so too soon (again). Researchers at the University of Glasgow, Scotland, have effectively done just that. Okay, so the team was using near perfect conditions: a 39-megapixel Hasselblad H2D camera, shooting a subject from one meter away, in perfect lighting, but the results proved the idea is well within the realms of science fact. When looking at a close up of a subject's eye, the team was able to grab an image between 27 to 36 pixels wide by 42 to 56 pixels high showing the face of one of the "bystanders" they had organised to be in the subject's view. The reflected images proved good enough that when volunteers were asked to match the small image with that of the actual bystander, or someone of similar appearance, results came in well above chance averaging between 70- and 84 percent. As well as assisting in criminal investigations, the researchers claim the technique could also yield 3D environments, when images can be taken from both eyes. Of course, real-world application would require similarly optimal conditions, but as technology advances, the researches claim this could be an ever increasing scenario.
University of Glasgow scientists print drugs in 3D, pave the way for in-home pharmacies
Breaking Bad in 3D? If recent work by a team of University of Glasgow scientists persists, that could soon be a hard reality -- just without the glasses. Taking what's typically been the province of sanitized laboratories and moving it outside, the group's devised an efficient method that makes use of commercial-grade three-dimensional printers to create "reactionware vessels": custom-designed, polymer gels that house and aide in chemical reactions. The technique, already viable on a larger, albeit slower scale, is not quite ready for primetime, but with future refinements could eventually trickle down into small businesses, or third-world countries where it'd be used for rapid medical treatment. And, in a hypothetical scenario that'll likely provoke scrutiny from the FDA and DEA, consumers might one day be able to save a trip to the drugstore and simply print from home -- a decidedly different spin on designer drugs -- using apps. Of course, this is all just speculation of potential future applications. We trust that humanity and enterprise will put this medication replication to noble use -- until it hits the club, that is.
Scientists attempt to give spark of life to all-synthetic metal cells
Just because it hasn't happened yet, doesn't mean it can't; at least that's what a Scottish research group is hoping as it attempts to create reproductive synthetic cells made completely from metal. At this stage, the idea of sentient metallic life remains a distant sci-fi dream, but researchers at the University of Glasgow have already birthed iChells -- inorganic chemical cells. These bubbles, formed from the likes of tungsten, oxygen and phosphorus, can already self-assemble, possess an internal structure, and are capable of the molecular in-and-outs expected of its biological counterparts. Researchers are still tackling how to give these little wonders the ability to self-replicate, and possibly evolve -- further cementing our doom post-Robot Apocalypse. Check out our future synthetic overlord's first steps in a video after the break.
Optical tweezers manipulate microscopic objects using an iPad, raw brainpower (video)
Okay, so maybe the whole brainpower thing is a distant second to the iPad itself, but still -- being a rocket scientist probably doesn't hurt when manipulating microscopic objects via a multitouch display. That's the kind of setup that students and boffins alike have going at England's University of Bristol, where iTweezers are being used to control a tiny rod about 300 nanometers wide, amongst other things. Essentially, the iPad is able to display what's under a microscope via a wireless display transfer, and then, touch points are converted into laser movements that are used to handle objects that are far smaller than those visible particles clogging up your left ear right now. All told, a user can select up to 11 different objects, and in theory, the iPad could enable scientists to do this remotely. Hey, we're all about new and improved ways to telework. Vid's below, kiddos.
Researchers create ultra-fast '1,000 core' processor, Intel also toys with the idea
We've already seen field programmable gate arrays (or FPGAs) used to create energy efficient supercomputers, but a team of researchers at the University of Glasgow led by Dr. Wim Vanderbauwhede now say that they have "effectively" created a 1,000 core processor based on the technology. To do that, the researchers divvied up the millions of transistors in the FPGA into 1,000 mini-circuits that are each able to process their own instructions -- which, while still a proof of concept, has already proven to be about twenty times faster than "modern computers" in some early tests. Interestingly, Intel has also been musing about the idea of a 1,000 core processor recently, with Timothy Mattson of the company's Microprocessor Technology Laboratory saying that such a processor is "feasible." He's referring to Intel's Single-chip Cloud Computer (or SCC, pictured here), which currently packs a whopping 48 cores, but could "theoretically" scale up to 1,000 cores. He does note, however, that there are a number of other complicating factors that could limit the number of cores that are actually useful -- namely, Amdahl's law (see below) -- but he says that Intel is "looking very hard at a range of applications that may indeed require that many cores."

Keio University developing 'olfactory printer,' AromaRama due for a resurgence
We're not entirely sure why people keep trying to bring back Smell-O-Vision, although Keio University's success in printing scents using a modified printer gives us hope that this sort of thing might someday be somewhat feasible -- and useful. It works by using an off-the-shelf Canon printer that's been given a "scent jet," Kenichi Okada told New Scientist. "We are using the ink-jet printer's ability to eject tiny pulses of material to achieve precise control." The scent dissipates quickly, after one or two human breaths. And while specific scents can be printed, there is as of yet no way to build a general purpose device. According to the University of Glasgow's Stephen Brewster: "We don't yet know how to synthesize all the scents we want. There is no red-green-blue for smell -- there are thousands of components needed." That's OK with us. In our experience, it's usually better that people keep their smells to themselves.
