Cornell scientists 3D print ears with help from rat tails and cow ears

Science! A team of bioengineers and physicians over at Cornell University recently detailed their work to 3D print lifelike ears that may be used to treat birth defects like microtia and assist those who have lost or damaged an ear due to an accident or cancer. The product, which is, "practically identical to the human ear," according to the school, was created using 3D printing and gels made from living cells -- collagen was gathered from rat tails and cartilage cells were taken from cow's ears. The whole process is quite quick, according to associate professor Lawrence Bonassar, who co-authored the report on the matter,

"It takes half a day to design the mold, a day or so to print it, 30 minutes to inject the gel, and we can remove the ear 15 minutes later. We trim the ear and then let it culture for several days in nourishing cell culture media before it is implanted."

The team is looking to implant the first ear in around three years, if all goes well.

NASA's Kepler telescope spots smallest planet to date, no aliens

NASA's Kepler telescope is permanently on the lookout for celestial objects of interest, and its latest discovery is a small one. A small planet, to be exact -- in fact, the smallest its encountered during its search. Kepler-37b is a tad larger than our heavenly dance partner, the Moon, and whizzes round a star much like our Sun, with two larger planets in its system for company. NASA's issuing back pats all round, as finding Kepler-37b has highlighted "the precision of the Kepler instrument" (although admittedly, the star's behavior was favorable), and suggests there are many more humble worlds of similar size awaiting our detection. It's unlikely any aliens call Kepler-37b home: it's thought to be rocky, with no atmosphere, and hugs its sun in a 13-day orbit cycle, meaning surface temperature is terribly high. Still, an achievement for Kepler, no doubt, but what we really want it to find is a planet home to beings who can explain the plot-line of Prometheus. We're still a little confused.

MIT imaging chip blends photos with and without flash, keeps detail in noise reduction

Mobile image processing in itself isn't special when even high dynamic range shooting is virtually instant, at least with NVIDIA's new Tegras. A new low-power MIT chip, however, may prove its worth by being a jack of all trades that works faster than software. It can apply HDR to photos and videos through near-immediate exposure bracketing, but it can also produce natural-looking flash images by combining the lit photo with an unassisted shot to fill in missing detail. Researchers further claim to have automatic noise reduction that safeguards detail through bilateral filtering, an established technique that uses brightness detection to avoid blurring edges. If you're wondering whether or not MIT's work will venture beyond the labs, don't -- the project was financed by contract manufacturing giant Foxconn, and it's already catching the eye of Microsoft Research. As long as Foxconn maintains interest through to production, pristine mobile photography won't be limited to a handful of devices.

Did you think 'The Avengers' finale was shot in New York Think again video

Raymond Teller once said that the secret to fooling people is to put in so much more effort than the trick seems worth. It seems that the bods at Industrial Light and Magic followed his wisdom when concocting the effects for The Avengers. If you'd marveled at how seamless the team had blended shots of the Big Apple with the Chitauri invasion, then we've got a surprise for you -- almost none of it is real. Rather than shoot parts of the New York-based finale in the city (or any other city), the effects house created a 20-block "digital playground," complete with individually detailed office windows. Interested in learning just how much of those breathtaking set pieces were filmed in a green screen in New Mexico? Head on past the break.

NTT's Visual SyncAR brings augmented reality to video, spices up the second screen (video)

The second screen has largely asked that you take your eyes away from the action, even if that is to play along in real-time. Visual SyncAR, however, brings that tablet or mobile right back into the thick of things. Developed by Japan's NTT, the platform uses digital watermarks that presents a timecode to the app running on the second device, allowing it to display content in sync with whatever is on the primary display. In the video after the break you can see the concept being illustrated with playful examples that interact with the program, but more useful applications include the ability for users to pull up subtitles for public information videos, or overlay sign language. Naturally, there's also a massive potential for advertisers, who we're sure would be more than keen to embrace the technology, and ably guide you from their commercial to an online outlet or additional promo material. Especially if they're selling a cure for all that inevitable arm ache...

Happy 540th Birthday, Copernicus, have a Google Doodle

It may be obvious now, but when Heliocentrism was cooked up by Nicolaus Copernicus, he was branded a heretic. The idea that the Earth orbited the Sun, conceived without the aid of any equipment, would only be proved half a century later, when Galileo built a telescope and pointed it heavenward. Fortunately, ol' Nick's contribution hasn't been forgotten, and so today's Google Doodle shows the planets all gently orbiting our nearest star.

NBA gives future Daryl Moreys access to the league's entire statistical history

The odds of rising from NBA stat junkie / forum poster to Houston Rockets GM like Daryl Morey did are slim, but thanks to the new NBA.com/Stats page fans have access to more data than ever before. Until now, only league and team personnel have had access to the NBA's complete official stats -- media got access last spring -- with box scores that go as far back as its start in 1946-47, individual stats for anyone who has ever played in the league plus advanced statistical breakdowns and rankings of best lineup combinations. Fan sites like Basketball Reference have filled in the gaps in the past, but this should bring a new level of accuracy and analysis to bear.

Access to these stats means we can evaluate games at a much deeper level to know precisely why the Lakers are so bad this season, or which combinations of players are giving the Knicks their best advantage. SAP announced the project back in July as a part of its marketing deal with the league, as it gets to show off its database chops building a system that can handle such a large number of requests on so much info. Hopefully other leagues follow suit and encourage this level for interaction with fans, although we suspect it would take more than a few Moneyball-esque calculations to fix squads like the Bobcats. Hit the source link below to satisfy a jones for numerics or find the perfect angle for your LeBron vs. Kobe argument, although last night's All-Star Game may have given all the ammo necessary.

Researchers testing frugal autonomous car system, aim for $150 price tag (video)

Google certainly has pockets deep enough to trick out self-driving cars with any kind of pricey gear, but researchers at the University of Oxford have begun testing a solution that aims to keep things affordable. Currently, the system leverages an array of low-profile stereo cameras and lasers that rings up at about £5,000 (approximately $7,750), but the next goal is to knock the price down to £500, and eventually to a cool £100 (roughly $150). "Really, we do need to solve the engineering challenges of not relying on expensive sensors, but relying on cheap sensors," Professor Paul Newman told the Telegraph. "But doing some really smart things with those cheap sensor feeds."

Rather than a vehicle that acts as a chauffeur at all times, Newman's vision for the modified Nissan Leaf, dubbed RobotCar, is for it to take control on select occasions. While drivers go about their commute, the system composes a 3D map of the car's environs and commits it to memory. When the auto identifies a familiar setting and feels confident about its ability to take the reigns, it could let the driver know it's ready to assume control. Right now, the automobile's been tested on private roads, but the team behind it is working with the UK's Department of Transportation to roll it onto public streets. Head past the jump for a glimpse of RobotCar in action.

Large Hadron Collider goes silent for two years of repairs and retrofits

We've long known that the Large Hadron Collider would need to take a break, but that doesn't take the edge off of the moment itself: as of Valentine's Day, the particle accelerator has conducted its last test for the next two years. The giant research ring will undergo sweeping repairs and upgrades that should should give it the superconducting connectors needed to hit the originally planned 14TeV of combined collision energy, versus the 8TeV it's been limited to almost since the beginning. CERN's machine arguably earned the downtime. After a rough start, it went on to produce rafts of collision data and healthy evidence of the elusive Higgs boson. If you're still down, think of the hiatus as doing us a favor -- it postpones any world-ending disasters until around 2015.

NOVA's Earth From Space documentary shows us our connected planet from above video

We've already had a meteorite shower to remind us that Earth is just a small part of a much, much larger universe. If that wasn't enough perspective for you, PBS is offering a follow-up through NOVA's newly streaming "Earth From Space" documentary. The two-hour show illustrates how our planet's individual climates and ecosystems are really part of one larger unit, with ripple effects that we didn't always anticipate until an abundance of earth observation satellites made them clear. You'll have to be an American to watch before the documentary, at least before it arrives in disc form on April 2nd. Every Earth citizen can still watch the trailer after the break.

If you fancy getting cosy with an asteroid that's got the destructive power of a nuclear arsenal, today's your lucky day. The wittily-named 2012 DA14 will sail past Australia at a distance of 17,510 miles early this afternoon, and while it won't be visible with the naked eye, NASA's got a few telescopes that'll do the job. It'll come into range at around 2:00pm ET, and is expected to be at its brightest about 25 minutes afterward. If your boss is sympathetic and you don't wanna miss a thing, head on past the break to catch the livestream, which started at 12:00pm ET. As for us? We're gonna spend the next few hours looking for Bruce Willis' phone number.

Meteorite shower crashes in Russia video

A meteorite shower has crash landed across Russia's Ural region, injuring over 250 900 people and damaging buildings in six cities. Residents in Chelyabinsk reported shaking ground, windows shattering and car alarms going off as the rocks fell to Earth. Officials in the country say that the shower began after a larger meteor disintegrated in the lower atmosphere, causing the fragments to wreak the (currently) non-lethal havoc. If you'd like to compare how wrong (or right) Michael Bay got it in Armageddon, head on past the break for some footage.

Autodesk partners with Lego to create interactive 3D Mindstorm plans

If you think it's hard putting the "Lego Discovery Fire Station" together, how about building and wiring a fully-functioning Mindstorm EV3 robot? To give you a leg up, the Danish toy outfit's joining forces with Autodesk to put together 3D interactive building instructions for the latest generation of Mindstorm mechs. The effects and 3D software firm will use its Inventor Publisher software to create interactive plans that run on iPads, Android devices and web browsers for five different 'bots. That way, you'll be able to actually put on your builder's hat and not just giggle enthusiastically at the final result.

Ready for a new radar system? The UK could be, if a new study is deemed a success. Thales, a French aerospace company which manufactures traditional radar systems, has received funding from the UK's Technology Strategy Board to study the feasibility of using TV signals to locate planes and choppers through a technology called "passive radar." According to the BBC, the system would monitor the timing of TV signals reflected from aircraft, which would enable equipment to display an exact location, while measuring the Doppler effect would provide speed and direction information.

Though it's not based on GPS, the new system would reportedly be more accurate and efficient than what's in use today, while also serving to free up spectrum that could be used for an upcoming 5G network. Unconvinced frequent fliers need not worry, however -- the country's existing radar infrastructure would remain intact throughout the test period, and air traffic control officials won't be switching to the new system unless it's sanctioned, which, considering the significance of such a move, could take some time.
