If you're hip to repurposing old tech for new inventions, Invisible is right up your alley. The Greensboro-based unit calls themselves a "mechanical music museum" and "a reverse engineered folk science daydream" when describing their elaborate set of sound-making contraptions and recycled video equipment. The outfit's effort The New Obsolete was part of the Moogfest happenings this weekend, and our curiosity was immediately piqued. This particular performance is labeled as "an exploded view of the strange romance between humans and technology."

Among all of the self-constructed instruments is the Selectric Piano: a typewriter that uses both computer and piano parts to control a keyboard. Each keystroke by the typist corresponds to a note added to collective soundscape and a mounted video camera allows the audience to keep tabs on the textual component. The project also showcases an object known as Elsewhere's Roof. The device controls a set of drum and percussion tools with water dropping into a few rather hi-tech Mason jars. In addition to arsenal of noise makers, multi-channel video and library of collected audio (via tape decks and turntables, of course) rounds out the lot. We were able to catch one of the stellar showings, so hit the gallery below for a look at the wares while a snippet of the action awaits beyond the break.

Invisible: The New Obsolete

Commercialization of carbon nanotubes is one of the holy grails of next-gen computing, and IBM thinks it's made crucial steps toward making this a reality. This isn't the first time that we've heard such a claim, of course, but IBM's considerable resources will make this particularly interesting. The specific problem it's been tackling is placing enough semiconducting nanotubes together to be useful in commercial chips, with current attempts being more in the hundreds, rather than billions that would be required. The new approach uses ion-exchange chemistry that allows controlled placement of nanotubes at two orders of magnitude greater than before, with a density of roughly a billion per square centimeter. To achieve this, the nanotubes are mixed with a soap-like substance that makes them water-soluble. Next, a substrate comprising two oxides and a hafnium oxide "trench" is immersed in the soap-solution, which results in the nanotubes attaching to the hafnium oxide canals with a chemical bond. Simple when you think about it! IBM hopes that as the materials and method are readily accessible now, that industry players will be able to experiment with nanotube technology at a much greater scale. Though, as we've become accustomed, there's no solid timescales on when this might realistically unfold.

We like to tell ourselves that learning by doing is the best strategy for improving our skills, but we seldom apply that philosophy to our robots; with certain exceptions, they're just supposed to know what to do from the start. Researchers at the Technical University of Darmstadt disagree and have developed algorithms proving that robot arms just need practice, practice, practice to learn complex activities. After some literal hand-holding with a human to understand the basics of a ping-pong swing, a TUD robot can gradually abstract those motions and return the ball in situations beyond the initial example. The technique is effective enough that the test arm took a mere hour of practice to successfully bounce back 88 percent of shots and compete with a human. That's certainly better than most of us fared after our first game. If all goes well, the science could lead to robots of all kinds that need only a small foundation of code to accomplish a lot. Just hope that the inevitable struggle between humans and robots isn't settled with a ping-pong match... it might end badly.

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

If, like us, you struggle to read the front of the Corn Flakes box of a morning, you likely gave up any hope of cracking ancient codes long ago. If you didn't, however, then your time might be now -- as one of the oldest scripts know to man is still up for grabs. Prefer just to observe? No problem, as we've got super-Earth-searching satellites, military mice and vertical farms, all for your viewing reading pleasure. If you hadn't guessed already, this is alt-week

They say a picture is worth a thousand words, but this just leaves us speechless. Pictured above is a compressed 108,500 x 81,500 pixel image of 84 million stars across central parts of the Milky Way. Taken by the VISTA survey telescope at the ESO's Paranal Observatory in Chile, this 9-gigapixel photo is the result of thousands of individual images being meshed together. If it were printed out at the average resolution of a standard book it would measure a mind-boggling 9 x 7 meters. Using three separate infrared filters, VISTA is able to see through dust fields that normally obscure the view of an optical telescope. By studying this monumental image, astronomers hope to gain a better understanding of how galaxies form and evolve. If you'd like to take a look at this galactic work of art in its entirety, you can do so by visiting the source link below.

Nintendo may have left its Vitality Sensor by the wayside, but researchers at Boston Children's Hospital are using heart rate monitoring in a video game to teach children with anger issues how to temper their emotions. Dubbed RAGE (Regulate and Gain Emotional) Control, the game tasks players with blasting hostile spaceships while keeping their heart rate from exceeding a predefined limit. If a gamer's pulse rises above the ceiling, they'll lose the ability to shoot until they can ease their pulse back down. A group of 18 kids who received standard treatments and played the game for five, 15-minute-long sessions had better control of their heart rate and lower anger levels than a group that only used traditional treatments. Currently, a controlled clinical trial of RAGE Control is underway and there are plans to take the concept a step further with toys and games suited for younger children. Look out below for the full press release or tap the second source link for the team's paper in the Journal of Adolescent Psychiatry.

A Berkeley Lab research team in California has successfully restored a 134 year-old audio recording. The historic audio was originally captured in 1878 by a phonograph designed by Thomas Edison, which consisted of a cylinder wrapped in tinfoil that used a stylus to record sound on the surface of the material. Due to the foil's frailty, recordings were only good for a few playbacks on Edison's phonograph. To restore this century-old mixtape, the research team created a 3D model of the grooves in the foil and ran it through a software that recreated the original audio track. As for the great mystery of the recording's contents, it's a 23-second horn instrumental followed by what is believed to be political writer Thomas Mason reciting Mary Had a Little Lamb and Old Mother Hubbard. Using modern technology for playback, the restored recording is set to have a listening party this week at the Museum of Innovation and Science in New York.

We've all had that moment where we sit in front of the keyboard and have trouble just getting started. It can be an especially dire problem when the 30-day deadline of National Novel Writing Month (NaNoWriMo) looms overhead, and that was enough for inventor Steve Hoefer to craft his own USB progress meter. The Arduino-based contraption advances a real-world dial or gauge as the word count reaches the NaNoWriMo servers, giving that extra incentive to meet a daily goal or hit the ultimate 50,000-word mark on time. Hoefer characterizes it as a simple project for those who know their way around an Arduino controller; the toughest part for them may just be constructing the box that keeps the meter presentable. Full instructions are available after the break, although we'd hurry to build the meter before November starts. It could all too easily be the source of the very procrastination we're trying to avoid.

3D render? The latest submission to deviantART? No, that's a microscopic photo of the blood-brain barrier in a live zebrafish embryo taken by Dr. Jennifer Peters and Dr. Michael Taylor at 20X magnification, and it's the latest winner of Nikon's annual Small World Photomicrography Competition. Not surprisingly, the runners-up in the contest (drawn from some 2,000 submissions) are just as impressive -- hit the links below for a look at all of them. Those interested in having themselves featured next year (and taking home up to $3,000 in Nikon gear) have until April 30th to get their submissions in for the next competition.

While Boston Dynamics' Cheetah has already premiered, speeding along on its robot-friendly treadmill, we've now got a better glimpse at how the similarly DARPA-funded human-hunting obstacle-scaling Atlas fares, courtesy of its ancestor. That's the Pet-Proto you can see in the video below, balancing and leaping across narrow terrain, conducting its own "autonomous decision-making" and keeping upright -- all very important points for DARPA's own Robotics Challenge, a competition where winners will gain access to their very own modified version of the Atlas for future disaster response tests. Watch the Pet-Proto gradually advance towards camera right after the break. And we'll sleep with one eye open.

At today's prices, building a Six Million Dollar Man would cost around $31 million. Of course, being a TV show means the Office of Scientific Intelligence doesn't have too many bionic employees, but that might not the case in the future. Nicolas Giuseppone and a team at the Université de Strasbourg and CNRS have created thousands of nano-machines to replicate the movement of human muscle fibers. Weaving them all together, the machines are able to make a coordinated contraction movement that stretches and contracts. For the moment, the supramolecular polymers can only stretch a matter of micrometers, but in the future they could be used to create artificial muscles, small robots or even materials that can move. Hopefully it'll also give us the power to leap tall buildings, so we'll be outside practicing our sound effects.

Dodging the issues of spectrum auctions and more cell towers, researchers at MIT have discovered that they can use an algebraic equation to improve data speeds by reducing dropped packets. It's these dropped packets that can build up congestion across a wireless network, as devices attempt to recoup these missing data nuggets. But instead of sending typical packets, MIT's Research Laboratory of Electronics created an equation that describes a series of packets. If a packet fails to deliver, then the receiving device is apparently able to "solve" the missing chunk, with the processing load on phones, routers and base stations apparently negligible.

The tech, which can also seamlessly transition a data stream between wireless internet and LTE, has already been tested on WiFi networks over at MIT; when two percent of data packets were dropped, speeds were boosted from 1Mbps to 16Mbps. If five percent of packets were being lost, the researchers then saw bandwidth increase from 0.5Mbps to 13.5Mbps. Companies are apparently already licensing the tech, although MIT isn't revealing more on this just yet. Muriel Medard, project lead, said that there were currently "very severe inefficiencies that should be remedied before you consider acquiring more resources" -- namely more spectrum and hardware, although the gains seen in these early tests are yet to be replicated in real life. There's more on the science and development at the source link below.

Things are buzzing late Monday afternoon at Carnegie Mellon's Planetary Robotics Lab Highbay. Outside, in front of the garage door-like entrance, a trio of men fills up a kiddie pool with a garden hose. Just to their left, an Enterprise rent-a-truck backs up and a handful of students raise two metal ramps up to its rear in order to drive a flashy rover up inside. I ask our guide, Jason Calaiaro, what the vehicle's final destination is. "NASA," he answers, simply. "We have a great relationship with NASA, and they help us test things."

Calaiaro is the CIO of Astrobotic Technology, an offshoot of the school that was founded a few years back, thanks to Google's Lunar X Prize announcement. And while none of the handful of vehicles the former student showcases were made specifically with the government space agency in mind, given the company's history of contractual work, we could well see them receive the NASA stamp of approval in the future. Asked to take us through the project, Calaiaro tells us, quite confidently, that the trio of vehicles behind us are set to "land on the moon in 2015," an ambitious goal set to occur exactly three weeks from last Friday.

Welcome to Growing Up Geek, a feature where we take a look back at our youth, and tell stories of growing up to be the nerds that we are. This week, we have our very own Philip Palermo!

In case you couldn't tell from that pirate / bandit / pimp / vampire pictured above, I sometimes have trouble making up my mind. It took me forever to decide what I wanted to be that Halloween -- figuring out what I wanted to be when I grew up has taken even longer.

It's strange to think that a few landmark tech purchases during my life helped make who I am today. Our family's first computer, the NES, a used DSLR -- just the simple act of bringing tech home and experimenting with it seemed to shape, reshape and re-reshape my projected career path.

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

Most mornings, we wake up with little to no idea what happened the day before, let alone last week. Fortunately, they don't let us run important scientific research projects. Or maybe they do, and we just forgot? This week (and most others as it goes) we definitely leave it to the pros, as we get some insightful glimpses at some important origins. Ball Lightning, the moon and even us humans are the benefactors of those tireless scientists, who work hard to explain where it all comes from. There's also a planet with four stars that sees the first few paragraphs of its origin story excitedly written out. One thing we never forget, however, is that this is alt-week.

Trying to launch a concerted nonprofit video campaign can feel like tilting at windmills: you might have one moment of undivided attention from viewers before they're off to watch cats and Nigerian pygmy goats. Google wants to make the most of that time through its YouTube Campaigns initiative. The strategy brings on-video overlays and channel sections that show viewers both a progress meter for the campaign as well as a handy links to explore and share what they've found. If all goes well, charities and like-minded organizations get more donations and YouTube views, while we in the general public are reminded that there's more to life than K-pop videos. It certainly beats manning the phones for a celebrity fundraiser.

One way that sensors can track your position without using an array of satellites is by measuring your acceleration as you move around -- but unless you're piloting a jumbo jet, current devices aren't very accurate. Researchers at Caltech hope to change all that with a new, ultra-sensitive accelerometer they developed, which uses laser light to detect motion changes. The scientists managed to shrink a so-called large-scale interferometer down to micro-scale sizes, creating a device "thousands of times faster than the most sensitive sensors used today." That could allow a smartphone with such a micro-sensor to detect your exact position even while inside a grocery store, and flash "ads and coupons for hot dog buns" while you're in the bread aisle, according to Caltech. All that sounds good, but we can perhaps think of more inspiring uses for the new tech.

Japan's four-inch FITSAT-1 orbiters were released from Japan's Kibo laboratory on the ISS last week to (literally) start their world tour, and astronauts aboard the station captured the wee satellites being dwarfed by giant solar arrays and our own blue rock on their way to orbit. Soon they'll be writing "Hi this is Niwaka Japan" in Morse code using intense flashes of LED light, first to Japan and then across the globe, starting next month. To catch them floating away from the International Space Station's cozy confines, hit the source.

While Felix Baumgartner landed safely on the ground just a matter of hours ago, the internet is still resonating with the sound of tweets, status updates and YouTube clicks, all thanks to what was one of the most spectacular human endeavors in recent history. The mission was simple, to send a man up in a balloon higher than ever before, and have him safely jump to the ground. This kind of "simple" is usually anything but -- if you just look past the well-manicured exterior. Which, as luck would have it is exactly what we did.

With the cheers of success still ringing in his ears, we got some quality time with Art Thompson, the technical project director, and Baumgartner's earliest collaborator on the Stratos mission. We wanted to know a little bit more about what went on behind the scenes, and Thompson was more than happy to oblige. They're understandably proud of what they just achieved.

Cardboard never ceases to amaze. Having been deployed in gramophones, stereos and even digital cameras, one inventor now believes it can be used to make the ideal bicycle. Izhar Gafni, from Israel, spent 18 months just folding the material every-which-way in order to discover a strong enough design, and now he claims his technique is almost ready for mass production. His maintenance-free bike uses a "secret" mix of organic materials to make it waterproof and fireproof, and is then lacquered to give it a friendlier appearance. It's expected to cost a mere $20 and weigh about 20 lbs (9 kg) -- that's 65 percent lighter than an average metal ride. In fact, this bicycle doesn't use any metal parts at all -- the solid tires are made of reconstituted rubber and a car timing belt is used instead of a chain. It lacks the swank of a Faraday Porteur, perhaps, but then you could buy 175 of these for the same money. Want proof that it actually works? The bike's not-so-featherweight inventor takes it for a spin after the break.
