Hasta La Gadget!

Teams at the Large Hadron Collider must be developing a knack for producing tangible evidence of theoretical particles. After orchestrating 2 million collisions between lead nuclei and protons, like the sort you see above, the collider’s Compact Muon Solenoid group and researchers at MIT suspect that stray, linked pairs of gluon particles in the mix were signs of color-glass condensate, a currently theory-only form of matter that sees gluons travel in liquid-like, quantum-entangled waves. The clues aren’t definitive, but they were also caught unexpectedly as part of a more routine collision run; the team is curious enough that it’s looking for more evidence during weeks of similar tests in January. Any conclusive proof of the condensate would have an impact both on how we understand particle production in collisions as well as the ways gluons and quarks are arranged inside protons. If so, the CMS and MIT teams may well answer a raft of questions about subatomic physics while further justifying CERN’s giant underground rings.

You wouldn’t immediately think of the ear’s cochlea as an energy source, but MIT knows that every mammal effectively has a pair of very small power plants because of the ionized environment. School researchers are trying to harness that energy through a new sensor that exploits the whole ear canal system. As eardrum vibrations naturally create a usable voltage from brain signals, the prototype can build enough charge in a capacitor to drive a very low-power wireless transmitter that relays the electrochemical properties of the ear and potentially diagnoses balance or hearing problems. The beauty of the system is its true self-sustainability: once the transmitter has been been jumpstarted with radio waves, it powers itself through the resulting transmissions. Energy use is also sufficiently miserly that the sensor doesn’t interrupt hearing. Work is still early enough that there’s a long way to go before such implants are part of any treatments, but there’s hope that future chip iterations could help fix inner ear maladies, not just report on them. Something tells us, however, that the doctor won’t ask us to take two dubstep tracks and call back in the morning.

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.

Last time we checked in with the 3D printing upstarts over at Formlabs, their Kickstarter was doing splendidly, having over doubled its initial funding target. Well, less than a month later, and with the money still rolling in, the current total stands (at time of writing) at a somewhat impressive $2,182,031 — over 20 times its initial goal. When we heard that the team behind it, along with some all important working printers, rolled into town, how could we resist taking the opportunity to catch up? The venue? London’s 3D print show. Where, amongst all the printed bracelets and figurines, the FORM 1 stood out like a sore thumb. A wonderfully orange, and geometrically formed one at that. We elbowed our way through the permanent four-deep crowd at their booth to take a closer look, and as the show is running for another two days, you can too if you’re in town. Or you could just click past the break for more.

Have you played the game Scribblenauts? I am quite sure that those who have given it a go would have most likely fallen in love with the title. Well, if you have a penchant for drawing stuff using a pencil, then this particular pencil from MIT is a little bit extra special. Chemists from MIT have managed to use a pencil where its graphite “lead” has been replaced by a special material that is known as carbon nanotubes. Basically, lines of carbon nanotubes are drawn on specially treated paper, and whenever an electrical current is fired through the paper, the change in resistance will be a sign that depicts the bonding of gas molecules to the nanotubes. So far, MIT’s test sensor has managed to detect small traces of ammonia gas successfully, and eventually, the whole idea of this exercise is to develop it in a way for it to function with just about any kind of gas. A smart pencil, if you will.
