DNP Physicists manipulate light on superconducting chips, forge path to quantum computing future

We're still years away from quantum computing becoming an everyday reality, but the physics geniuses over at the University of California Santa Barbara have made a discovery that might speed that process along. A team under professor John Martinis' tutelage has developed a way to manipulate light on a superconducting chip at the quantum level, allowing the group to control the wave forms of released photons with a switch and a resonator. That might not seem like much, but it's ultimately a launching pad for much more. With photons now bowing to researchers' whims, the next step is to see if the particles can securely transfer data over long distances, such as between Earth and orbiting satellites, or just from one end of the world to another. It's a lofty goal to be sure, but nobody said the revolution would be over in a day.

Curiosity rover leaves safe mode, remains in Martian limbo

The Curiosity rover has been in an especially precarious position since late last week, when a memory glitch forced it into a safe mode while NASA prepared a backup and diagnosed the trouble. We're glad to report that the worst is over. Scientists have confirmed that the rover left safe mode later on Saturday and started using its high-gain antenna for communication a day later. However, it's not quite out of the woods yet -- if Mars had woods, that is. The backup is still taking on the information it needs to assume full responsibility, and NASA wants to evaluate the suitability of the one-time primary computer as the new backup. Nonetheless, all the early indicators point to Martian exploration going back on track within days.

Inspiration Mars mission will use human waste for radiation shielding no really, it works

Dennis Tito is planning an ambitious private flyby of Mars for 2018 that will carry all kinds of logistical challenges during its proposed 501-day span, not the least of which is shielding the crew from radiation without consuming valuable resources. The team's solution is a clever one, if not especially pretty: human waste. While the walls of the Inspiration Mars spacecraft will initially be lined with water-filled bags to guard against cosmic rays, their contents will be gradually replaced with er, byproduct that will be dehydrated through the bag (possibly using polyethylene) to reclaim and purify water for drinking. As water-based materials are better at stopping radiation than metal, the approach theoretically represents the best of all worlds with less bulk, a simpler life support system and maximum room for supplies. If the Inspiration Mars group can keep the bags working at high efficiency in space, it won't have to worry about its travelers' safety; their comfort with being surrounded by their own waste may be another matter.

Alt-week peels back the covers on some of the more curious sci-tech stories from the last seven days.

Alt-week 3.2.13: A mission to Mars, robosparrow and facial recognition in fertility treatment

Life -- as they say -- is short. So, you gotta cram in as much as you can while you're here. Right? How about a once in a lifetime trip around Mars? Well, if that's on your bucket list, then you might just be in luck. There's other news pertaining to one of life's biggest events over the fold, too, but we'll leave you to figure out which story that is. Hint: it's not the robotic bird. This is alt-week.

Didn't get enough of the Dragon capsule launch this week? Good news, because after a day's delay due to (now remedied, according to NASA and SpaceX) faults with three clusters of its Draco thrusters, the capsule is set to be grappled by the International Space Station at 6:31AM ET on March 3rd (tomorrow morning). If you'll recall, the mission is mainly aimed at getting refreshed supplies and some experiments up to the space station. As an aside, NASA also notes that Dragon is still set to arrive back on earth for a splashdown on the 25th, as initially planned. If you're up for it, NASA TV coverage starts at 3:30AM the same day and the final berthing process (actually getting the capsule connected to the ISS) should happen after 8AM -- all that said, initial "orbital maneuvers" are set for 2AM, according to a tweet from Elon Musk. For more details on this stage of the mission, including those involved, blast over to the NASA source link below -- and make sure you've got enough coffee ready.

Curiosity rover flipped into 'safe mode' to overcome glitches

NASA's Curiosity rover has mostly had smooth sailing since it touched down on Mars last year. Unfortunately, it's in a more precarious position as of this past Thursday. After noticing corrupted memory files on the robot's primary computer, overseers have kicked Curiosity into a "safe mode" with a backup computer while they determine what's wrong and deliver any viable fixes. Don't think of this like you would the Safe Mode on a Windows PC, though. While the backup can serve as a replacement for the main computer, project manager Richard Cook warns Space.com that it will likely take "several days" to supply enough information that the failsafe can take over. NASA will switch back to the main computer if and when it's ready; if it is, the agency hopes to harden the code against future flaws. Curiosity will effectively stay on ice in the meantime... and not the variety it might want to find.

Welcome to The After Math, where we attempt to summarize this week's tech news through numbers, decimal places and percentages.

The After Math Barcelona's mobile bonanza, Big Dog and brain doctors

Barcelona's Mobile World Congress may have formed the backbone for this week's news but there was also notable news elsewhere -- like the fact that Boston Dynamics' upgraded quadruped robot can now throw cinder blocks. We'll be sticking closer to the (safer) events in Spain, however, so take a look for yourself after the break.

Duke University melds two rats' thoughts over the internet we're not sure Spock would approve

Some would say the internet already lets us share every minute detail of our thoughts, much to our followers' dismay. Duke University isn't deterred by our behavior -- if anything, it just took oversharing literally by connecting two rats' minds in an experiment, first in a lab and ultimately online. Electrodes attached to the brain of a host "encoder" rat in Brazil processed the motor-oriented mental activity for a desired behavior, such as pressing a lever on cue, and converted it into a signal that was then received by a "decoder" rat as far away as Duke's US campus. The majority of the time, the decoder rat performed the same action as the encoder. Researchers also found that rewarding the encoder alongside the decoder created a virtuous loop, as treating the first rat for a job well done focused its attention and improved the signal strength.

We're not sure that Vulcans would endorse this kind of mind meld, though: apart from immediately depriving the decoder rat of self-control, prolonged testing led to the same rodent developing additional sympathetic reactions to the encoder. There's also concerns that the test was too binary and didn't reflect the complexity of the whole brain. All the same, Duke's study is proof enough that we can export brainwaves in a meaningful way.

3D Feh MIT has already moved on to 4D printing video

The bad news: just as much of the world is starting to get excited about the prospects of 3D printing, science is moving on to the world of 4D. The good news: in the future, you might not have to assemble that Ikea chair yourself. "4D printing" is the term cientists are using to refer to a technology that MIT's Skylar Tibbits talked up during a recent TED appearance. The fourth "d" here is time, referring to an object that, once printed, is capable of changing shape (over time, naturally).

"Essentially the printing is nothing new," Tibbits told the BBC. "It is about what happens after." So far the concept has been demonstrated with thin strands of plastic, which, once added to water, form into a predetermined shape, using energy from the absorption. Suggested future applications involve furniture, pipes, bikes and buildings. First, however, scientists will have to demonstrate the technology on a larger structure, of course, and they'll explore the possibility of other energy sources, like heat, sound and vibration.

Sony Ericsson Windows Phone prototype slides onto eBay, wants us to call her Julie

eBay is as close as it comes to a genuine Aladdin's cave, and we've seen plenty of ancient rarities, prototypes, sci-fi weaponry, and the odd killer robot go under its gavel. One of the latest artifacts of interest comes from eBay's Netherlands site, which is hosting an auction for a Windows Phone prototype slider known to her friends as Julie (or Jolie, depending on where you look in the listing) from the now defunct Sony Ericsson partnership. The phone that never was from the company that is no longer is allegedly one of only seven units made, and is touted as having an 8-megapixel shooter and 16 gigs of storage. Some digging through the XDA Developers' forum suggests the handset's old Windows Phone 7 ROM is basically non-functional, so don't expect to plug in your SIM and stroll out the door with a useable device. If that doesn't put you off, however, there's no exorbitant entry price, and bids remain sensible, for now. Head to the listing below for more pictures and to get in on the action, but bear in mind the only shipping options are for Europe. Nothing a PM with an outrageous offer won't rectify, surely.

Update: The seller has been in contact to let us know that international shipping is now available, and while the WP7 ROM running on the handset is by no means a final build, there are no issues with voice calling, the camera or Bluetooth.

Stretchable, serpentine lithiumion battery works at three times its size

While we've seen more than a few flexible batteries in our day, they're not usually that great at withstanding tugs and pulls. A team-up between Northwestern University and the University of Illinois could give lithium-ion batteries that extreme elasticity with few of the drawbacks you'd expect. To make a stretchable battery that still maintains a typical density, researchers built electrode interconnects from serpentine metal wires that have even more wavy wires inside; the wires don't require much space in normal use, but will unfurl in an ordered sequence as they're pulled to their limits. The result is a prototype battery that can expand to three times its normal size, but can still last for eight to nine hours. It could also charge wirelessly, and thus would be wearable under the skin as well as over -- imagine fully powered implants where an external battery is impractical or unsightly. There's no word yet on whether there will be refined versions coming to real-world products, but we hope any developments arrive quickly enough to give stretchable electronics a viable power source.

Firefighters already use infrared cameras to find people in burning buildings, but the technology can't distinguish between a person's heat and that of the surrounding fire. That's because a zoom lens is needed to concentrate the infrared rays in a way that enables the apparatus to form a human-readable image. Fortunately, a team of researchers from the Italian Institute of Optics has developed a system that ditches the lens in favor of digital holography that produces detailed 3D images in the darkness. The hardware isn't out of short trousers just yet, but the team is planning to develop a portable version for field work -- and chief Pietro Ferraro hopes that the idea will be co-opted by the aerospace and biomedical industries, too. Curious to see what all the fuss is about? Head on past the break for a video.

DARPA trying again to develop a highspeed VTOL aircraft

If at first your unmanned aerial vehicles don't succeed... try, try again? After a series of unsuccessful tests with the Boeing X-50 Dragonfly and Groen Heliplane, the US government is once again trying to develop a high-speed, vertical takeoff-and-landing (VTOL) aircraft. DARPA just announced the VTOL X-Plane program, a 52-month, $130 million project with one mission: to build an aircraft that can exceed 300 knots, achieve a hover efficiency of 75 percent or better, and hit a cruise lift-to-drag ratio of 10 or more.

In layman's terms, such an aircraft would be faster than a traditional helicopter, but still have better hover efficiency than a modern high-speed 'copter. Sounds like a sensible idea, right? The thing is, DARPA doesn't know yet how such a thing would look: for now, the agency is merely soliciting proposals, with a particular emphasis on smaller, non-traditional companies nimble enough to develop products quickly. So if you've got any good ideas, may as well head on over to the source link, we guess, and try your luck.

MIT algorithm teaches robots to think outside of the mechanical box video

Although robots are getting better at adapting to the real world, they still tend to tackle challenges with a fixed set of alternatives that can quickly become impractical as objects (and more advanced robots) complicate the situation. Two MIT students, Jennifer Barry and Annie Holladay, have developed fresh algorithms that could help robot arms improvise. Barry's method tells the robot about an object's nature, focusing its attention on the most effective interactions -- sliding a plate until it's more easily picked up, for example. Holladay, meanwhile, turns collision detection on its head to funnel an object into place, such as balancing a delicate object with a free arm before setting that object down. Although the existing code for either approach currently requires plugging in existing data, their creators ultimately want more flexible code that determines qualities on the spot and reacts accordingly. Long-term development could nudge us closer to robots with truly general-purpose code -- a welcome relief from the one-track minds the machines often have today.

Nexus One launched into space on CubeSat, becomes first PhoneSat in orbit (video)

Google's Nexus One has dreamt of space travel for a while now, but on Monday it was finally launched into orbit aboard a CubeSat dubbed STRaND-1, which was developed by Surrey Satellite Technology and the University of Surrey's Surrey Space Centre. STRaND-1 now holds the honor of being the first PhoneSat and UK CubeSat that has made it into orbit. Alongside the HTC-made handset are an altitude and orbit control system, two propulsion setups and a Linux-based computer with a "high-speed" processor. After the Tux-friendly rig conducts a battery of tests, it'll relinquish control of much of the satellite's functions to the smartphone, which still runs Android.

Not only will the mission test how commercial, off-the-shelf tech can survive in the vacuum and conduct experiments, but it'll squeeze in some fun courtesy of apps developed by winners of a competition held last year. An app called 360 will let folks back on terra firma request their own snapshots of earth taken with the phone's shooter and pin them to a map. Ridley Scott might like to say no one can hear you scream in space, but another application loaded onto the device will put that to the test by playing user-submitted shrieks and recording them with the handset's microphone as they playback. Hit the break for more details and a brief video overview of the satellite, or jab the more coverage links to partake in the app shenanigans.
