Quantum 'compass' promises navigation without using GPS
GPS is vital to modern navigation, but it's extremely fragile. Never mind coverage -- if a satellite fails or there's a jamming attack, it quickly becomes useless. Scientists may have a much more robust answer, though. Scientists have demonstrated a "commercially viable" quantum accelerometer that could provide navigation without GPS or other satellite technology. The device uses lasers to cool atoms to extremely low temperatures, and then measures the quantum wave properties of those atoms as they respond to acceleration.
SpiderMAV drone shoots 'webs' at walls to perch in place
Consumer drones have more or less conquered hovering, but are there easier ways to stay in place? Researchers from Imperial College London have a possible answer: The SpiderMAV, a UAV that shoots ropes that magnetically cling to surfaces to anchor itself in place.
Test can show if the speed of light has changed
Modern science assumes that the speed of light has always been the same. Researchers have suggested that this seeming constant might have changed over time, however, and they now have a way to find out whether or not that's true. Professors João Magueijo and Niayesh Afshordi have developed a prediction that should test for changes in light speed. They've given the fluctuations in density the early universe, detectable through cosmic background radiation, an exact spectral index number based on the theory that light was much faster in the first seconds following the Big Bang (0.96478, if you're curious). If future measurements of the index line up with this number, they'll support the notion that light speed has shifted.
Scientists developed a USB stick that can perform an HIV test
When is comes to HIV tests, a drop of blood and a USB stick may be all patients need in the near future. Scientists at the Imperial College London developed a device with the help of medical testing company DNA Electronics that detects HIV levels in the bloodstream and creates a signal that can be read using a computer or handheld gadget. The disposable testing units could be used to help HIV patients monitor their treatment as well as improve how doctors manage the virus in remote locations.
Gene test spots all known inherited heart conditions
You might never have to worry that you'll fall victim to a heart condition passed along by your family. Researchers have developed a blood test that can reliably detect all known inherited heart problems, like genetically-based arrhythmia -- if doctors know about it, they can spot it. Previous tests only looked at a handful of genes and were only useful in certain circumstances, but the new technique identifies flaws in all 174 genes linked to the potentially life-threatening issues.
Wearable sleeve could improve stroke recovery therapy
When it comes to tools that help stroke victims on their way to recovery, we've seen exoskeletons of sorts to medicine covered clot-busting nanoparticles. But researchers from the University of South Hampton and Imperial College London have something altogether different cooked up: a wireless sleeve that gathers information of how a patient's muscles react during home therapy. As the school tells it, this sleeve, dubbed M-Mark, is the first to bring mechanomyogrpahy sensors (essentially ultra-sensitive microphones that measure muscle contraction) together with tri-axial accelerometers, gyroscopes and magnetometers.
Scientists want to laser-heat stuff to ten million degrees
Researchers at Imperial College London believe that they've created a method that could prove critical in the search for unlimited clean energy. The team has produced a theoretical method that, at least on paper, is capable of super-heating an object to ten million degrees in a fraction of a second. It's hoped that technology like this, if proven in the real world, will form a key component of a fusion reactor that'll provide a warm light for all mankind.
Eye-tracking robot arm lets you paint while you eat
One day, you might not have to even touch a canvas to make a masterpiece. Scientists from Imperial College London have developed a system that lets you paint hands-free through a combination of eye tracking and a robotic arm. All you do is adjust your gaze and blink at the right times -- you can even munch on breakfast while you're in mid-oeuvre. The technology is crude at the moment, but it should eventually become intuitive enough that you can focus on perfecting your style, rather than mastering the basics.
Vibrating pen makes it easier for Parkinson's patients to write
The ARC pen pictured above might look laughably large, but it could be the perfect option for folks with Parkinson's disease. It was created by a group of students from UK's Royal College of Art and the Imperial College London to combat a Parkinson's symptom called micrographia. That's characterized by a patient's handwriting becoming smaller and more cramped as they go along, to the point that it's not readable anymore. This pen prevents that from happening by stimulating key muscles through vibration (it's equipped with motors to make that happen), giving users more control over their hands. Further, its large size makes it more comfortable to hold than regular pens.
'Bleeding' pants can show paralympians that they're injured
One of the biggest worries paralympians have is sustaining injuries in areas where they won't be able to feel it. After all, if they don't even know they're injured, they might end up bleeding to death. That's why a group of students from London's Imperial College and The Royal College of Art have teamed up to create Bruise pants, which show paralympians where they're injured and how severe it is. The designers sewed pressure-sensitive films made by Fuji onto a pair of Lycra leggings, marking vital points where injuries would be most damaging. In the event that any of those areas sustain impact damage, the film develops a red stain similar to blood seeping through cloth. If the color's showing up as a deep, dark magenta, that means it's time to stop and find the medics.
Scientists find a way to create matter from light
Scientists have long theorized that you can create matter from light by colliding photons, but proving that theory has been a different story -- you need the right high-energy particles to even think of trying. However, it looks like that once-impossible dream is close to becoming reality. Researchers at Imperial College London have discovered a technique that should produce electrons and positrons by colliding two sets of super-energetic photons. To create the first batch of photons, you have to first blast electrons with a laser, and then shoot them at a piece of gold; you produce the other batch by firing a laser at the inside of a small gold can to produce a thermal radiation field. If you collide the two photon sources inside the can, you should see electrons and positrons spilling out.
Med students develop knife that can detect cancerous tissues within seconds
Here's one for the medical journals: researchers at London's Imperial College have created a high-tech scalpel that can differentiate between cancerous and non-cancerous tissue as it cuts. The team calls it the iKnife (intelligent knife), and by analyzing vapors created during electrosurgical dissection in real time, it takes only seconds to distinguish healthy flesh from affected tissue. The device's inventor, Zoltan Takats, says it has the potential to speed up cancer surgery considerably, as current analysis techniques performed mid-operation can take up to 30 minutes. It could also prevent follow-up surgeries prompted by undetected cancer cells. Unfortunately, the iKnife still has to go through more tests before we can add it to our arsenal of weapons against cancer -- until then, we'll just have to make do with run-of-the-mill electrosurgical knives.

Experimental game dev AI launches first official game, free for the holidays
"Angelina" is the brainchild of Imperial College London computer science PhD student Michael Cook, and it's just helped craft its first official game release: A Puzzling Present. You read that correctly -- a computer AI helped to develop, test, and produce a full on video game (which was subsequently released to the Google Play store late last week). The game's even free, should you not trust a synthetic brain to produce your Santa-based mobile platformers. Cook revealed his project to the world back in March as part of his PhD work -- he calls it, "an investigation into the ways in which software can design creatively." And while the theme of A Puzzling Present isn't exactly what we'd call wildly creative, Cook promises the level design and sheer fun to be top notch. Or at least he's hoping as much, lest Angelina's algorithms need adjusting -- regardless, the game is currently free on Android, should you wish to test your wits against a cold, calculating machine (and who doesn't?).
NPL, Imperial College create room-temperature maser, promise more sensitive beams
Masers, or microwave lasers, have rarely been as viable as their regular counterparts; they need temperatures near absolute zero, exotic vacuum chambers or strong magnets just to run at all, which safely rules out carrying a maser as a pocket pointer. The National Physical Laboratory and Imperial College London might put that gap in practicality to bed after developing a maser that can run at room temperatures. Instead of using ruby to boost the microwave strength, the scientists rely on a less pronounceable p-terphenyl crystal treated with pentacene that can handle ordinary amounts of heat. There's still much work left in refining the technology: it has yet to stay active for sustained periods, only works in a narrow bandwidth and chews through an ample amount of power. Once it's given the appropriate polish, however, the extra sensitivity of the improved maser could be a boon for medical scanning, bomb disposal or even future space communication that could punch through the atmosphere.
Researchers use off-the-shelf parts to let you write emails with your eyes (video)
There's a lot of research to help the spinal cord or stroke-injured become more self-sufficient, but it often takes some exotic paraphernalia. To buck that trend, scientists from Imperial College London showed that subjects could perform relatively hard tasks like writing messages and playing Pong using eye movement -- with a mere $35-worth of parts. They even showed how well the system worked, with subjects scoring within 20 percent of an able-bodied person after a scant 10 minutes of practice. The tracker works with two video console cameras and a pair of eyeglasses that, after calibration, can precisely track the pupils -- allowing them to control a cursor or move a paddle. The researchers also figured out how to "click" the eye-mouse by winking, and can even use more precise adjustments to calculate gaze depth -- meaning subjects will be able to perform more complex tasks in the future, like guide a motorized wheelchair. While by no means the first eye-tracking system we've seen, it's by far the most economical. Check the video after the break to see how it works.
Intel funnels $40 million into global network of research laboratories
Like any tech company worth its weight in silicon, Intel puts plenty of cash into research, often partnering with outside labs and schools that are less concerned with turning every project into a multi-billion dollar product. After throwing $30 million at Carnegie Mellon last year to open two new labs, Chipzilla is investing $40 million more in a global network of university research centers. Over the next five years that money will be rolled out to what the company is calling, Intel Collaborative Research Institutes (ICRI). The ICRI are based on the same premise as Intel's Science and Technology Centers, like those opened at Mellon, except with a global reach. Two existing labs, the Intel Visual Computing Institute at Saarland University and the Intel-NTU Connected Context Computing Center at National Taiwan University are being rolled into the program. In addition, three new centers are being opened up, including ICRIs for Sustainable Connected Cities in the United Kingdom, Secure Computing at the Technische Universität Darmstadt and Computational Intelligence at the Technion-Israel Institute of Technology. For more info on what sort or work they'll be doing at the various labs check out the PR after the break.
Angelina: the experimental AI that's coming for our game dev jobs
Ok so, maybe Angelina couldn't have created Skyrim all on her own, but the experimental AI from Michael Cook (a computer scientist at Imperial College London) is still quite impressive. The artificial dev is able program enemy behavior, layout levels, and distribute power ups with random attributes. While many elements of a game like Space Station Invaders (which you can play at the more coverage link) are designed by human hands, it's Angelina's ability to act as a composer building something fun from the various ingredients that's so interesting. Before setting a level in stone she plays through the possible combinations, determining which will be most enjoyable for a human player. Hit up the source link for loads more info.
Scientists produce stronger T-rays, bring Tricorders closer to reality
A group of scientists from Imperial College London and Singapore's Institute of Materials Research and Engineering (IMRE) have developed a new technique that could have far reaching impacts for Star Trek fans everywhere. It all involves something known as Terahertz (THz), or T-rays: electromagnetic rays that have already been used in full-body airport scanners and have the potential to be used across a much broader range of medical and environmental applications. Because every molecule can be uniquely identified within the THz range, these T-rays can be used to pick up on cancerous cells and other biological matter, perhaps even within a Tricorder-like scanner. Now, Imperial College's Stefan Maier and his team of scientists say they've found a way to create a stronger beam of T-rays, using so-called "nano-antennas" to generate an amplified THz field. In fact, this field can produce about 100 times more power than most other THz sources, which could allow for sharper imaging devices. "T-rays promise to revolutionize medical scanning to make it faster and more convenient, potentially relieving patients from the inconvenience of complicated diagnostic procedures and the stress of waiting for accurate results," Maier explained. "Thanks to modern nanotechnology and nanofabrication, we have made a real breakthrough in the generation of T-rays that takes us a step closer to these new scanning devices."

Growing Up Geek: Richard Lai
Welcome to Growing Up Geek, an ongoing feature where we take a look back at our youth and tell stories of growing up to be the nerds that we are. Today, we have our very own Senior Associate Editor, Richard Lai, who also happens to be the Editor-in-chief of Engadget Chinese. I've come to the point in life where I stop paying attention to my age, though it's still fun to make people guess it for their reaction -- you'll find out after the break, but here's a hint: I've spent the same number of years in both Hong Kong and the UK, plus a couple of years in Australia. Such a combination has turned me into a Chinese guy who speaks both British English and two Chinese dialects while holding an Australian passport; but I tend to skip all this and say that I'm a spy with many gadgets.
Nanopore DNA sequencing technique promises entire genome in minutes or your money back
Those vaguely affordable DNA tests that promise to tell you just how likely you are to be stricken by some horrible and unavoidable genetic affliction in the future? They only look at a tiny fraction of the bits and bobs and bases that make up your genetic code. There's a race on to develop a quick and inexpensive way to sequence a human's entire genome, a process that costs about a million thousands of dollars now and takes ages but, via the technique under development at Imperial College London, could be done in a few minutes for a couple of bucks in 10 years. The process relies on nanopores, which are the go-to tech for companies trying to pull this off. Basically, a DNA strand is pushed through a 2nm hole on a silicon chip and, as it moves through, that chip is able to use an electrical charge to read the strand's coding sequence. That is then spit out to a supercomputer to crunch the numbers at a speed of 10 million bases per second and, within minutes, you too can have some hard data to make you freak out about the future -- and maybe a place to put your iPod, too. Update: As many of you pointed out, there are multiple places to get your full genome scanned now for prices in the mere thousands of dollars. Pocket change, really.
