Researchers craft all-electric spintronics, vie for guest spot on Mindfreak

Unfortunately for us, we've no certified rocket scientist on staff. That said, we're absolutely convinced that the whiz-kids over at the University of Cincinnati are more than up to the task of improving a science that may or may not actually be useful in real things before 3028. As we continue to hear more about spintronics (described as "transistors that function by controlling an electron's spin instead of its charge"), a team of UC researchers have stumbled upon a novel way to control an electron's spin orientation using purely electrical means. In fact, one member calls this discovery the "holy grail of semiconductor spintronics," though we're guessing it'll still be a few years centuries before our hard drives are fetching data 100,000x faster and our batteries last longer than our desire to use them.

NC State gurus develop new material to boost data storage, conserve energy

We've all assumed that anything's possible when dabbling in the elusive realm of spintronics, and it seems as if a team at NC State University is out to prove just that. While using their newfound free time on Saturdays (you know, given that the football team has quit mid-season), Dr. Jagdish Narayan and company have utilized the process of selective doping in order to construct a new type of metallic ceramic that could be used to create a "fingernail-size computer chip to store the equivalent of 20 high-definition DVDs or 250 million pages of text." The material could also be used (in theory, anyway) to create a new generation of ceramic engines that could withstand twice the heat of normal engines and hit MPG ratings of 80. Granted, this all sounds like wishful thinking at the moment, but we wouldn't put it past the whiz kids in Raleigh to bring this stuff to market. Too bad the athletic director doesn't posses the same type of initiative.

Prosthetic, robotic 'Smart Hand' has feelings, too

Researchers in Italy and Sweden have spent the last ten years developing what they call the "Smart Hand," a prosthetic hand which enables feeling in its fingertips. The hand -- which was recently wired up to a test patient through a surgical procedure -- has four motors and forty sensors which are linked directly to the brain. In the surgery, the nerve endings of the patient were linked up to receptors in the hand, which allows for feeling in the fingertips of the hand, even though the hand is not really a part of his body. In the video after the break, you can see the greater precision and dexterity this hand allows for. Though the research still needs to be refined before practical use, it looks pretty far along -- and pretty awesome -- to us.

Physicists calculate the end of Moore's Law, clearly don't believe in Moore's Law


If you're looking for pundits with an end date for Moore's Law, you don't have to look far. You also don't have to look far to find a gaggle of loonies who just knew the world was ending in Y2K, so make of that what you will. The latest duo looking to call the demise of the processor mantra that has held true for two score comes from Boston University, with physicists Lev Levitin and Tommaso Toffoli asserting that a quantum limit would be achieved in around 75 to 80 years. Scott Aaronson, an attention-getter at MIT, expects that very same limit to be hit in just 20 years. Of course, there's plenty of technobabble to explain the what's and how's behind all this, but considering that the brainiacs of the world can't even agree with Gordon Moore's own doomsday date, we're choosing to plug our ears and keep on believin' for now.

Mad scientists figure out how to write memories to brains, take over Earth

Call us crazy, but we're guessing one Gero Miesenböck of the University of Oxford has been watching just a wee bit too much Fringe. Gero here, along with a few of his over-anxious colleagues, has seemingly figured out a way to actually write memories onto a fruit fly's brain using only a laser pen and three-fourths of a Ouija board. We know what you're thinking, and we're thinking the same. But all terrifying thoughts aside, what if boffins could burn memories of hard lessons learned into our minds without us having to suffer through them first? You know, like upgrading to Snow Leopard.

Large Hadron Collider staying cool at just a hair above absolute zero temperatures

Ah, Large Hadron Collider, our old frienemy, how close is thy doomsday clock now? Closer than it was last week, naturally, especially now that the temperature in each of its eight sectors has been dropped to 1.9 Kelvin, or -271 degrees Celsius / -456 Fahrenheit, depending on your equivalent measurement of choice. While pretty much lethal for humans, that's still twice as warm as the Boomerang Nebula some 5,000 light years away from our fair planet, making it a veritable vacation spot for those carnivorous inhabitants of the Centaurus constellation (not that they'd really want to make that big of a trek without some sort of pre-planned hotel accommodations, but we digress). The chill is all a part of the massive science experiment's ramp up to its second half of November relaunch -- assuming the personification of Higgs boson doesn't pop in via its proverbial TARDIS equivalent wearing a cape and carrying an anti-LHC particle gun, that is.

Mice run through Quake, Princeton neuroscientists scan their brains for traces of evil (video)

Want to know just how prevalent technology has become in our lives? Now even lab mice get Quake-derived virtual reality playgrounds to navigate instead of their old school wooden mazes. In all honesty, this appears a significant and praiseworthy advancement, as the Princeton team have succeeded in mapping brain activity right down to the cellular level, with real-time tracking of single neurons now possible. The Orwellian-looking setup above is necessary in order to keep the mouse's head immobile, and thus capable of being studied, while the animal moves around and its brain performs motion-related tasks. Go past the break to see a schematic of the scanner and a quite unmissable video of it in action.

Might Higgs boson be a time-traveling ne'er do well out to destroy the LHC?


We've certainly seen our fair share of crackpot theories regarding the Large Hadron Collider, and quite frankly the whole thing is becoming rather old hat. That said, when the New York Times comes up with something as far out as this, we most certainly have to share it with you. It seems that way back in July, 2007 two theoretical physicists (Danish string theory pioneer Holger Bech Nielsen and the Japanese physicist Masao Ninomiya), proposed an unlikely explanation as to why the LHC and the Superconducting Supercollider before it seem to be particularly accident prone. According to science writer Dennis Overbye, the Higgs boson (which the collider has been designed to observe) "might be so abhorrent to nature that its creation would ripple backward through time and stop the collider before it could make one, like a time traveler who goes back in time to kill his grandfather." Makes sense, right? Of course, we don't have any idea how these elementary particles might actually conduct the business of destroying equipment, but that hasn't stopped the duo from proposing a novel way to test this theory.

According to a paper published earlier this month, a simple deck of cards could be made, either out of construction paper or, if you're feeling high tech, simulated on a computer. The deck would have one card indicating that the LHC should be shut down, and a much larger number of cards (maybe 100 million or so) that indicate that everything is good to go. If you draw the death card, as it were, you can bet that the shadowy hand of the Higgs boson is stretching back in time, telling you to halt the operation. Between all this and the proposed hyperdrive propulsion tests we came across a couple days ago, things are starting to get very Philip K. Dick over at CERN. Can we make one suggestion? Instead of a random number generator, why not Tarot cards? Or a Ouija board? You know, go for a Halloween vibe.

Dow's POWERHOUSE solar shingles get along with non-solar siblings, your HOA

Oh sure, massive photovoltaic installations on rooftops are nothing terribly new, but by and large, the ones we've seen are stuck on massive warehouses or elaborate stadiums in foreign lands. Dow Chemical is doing its darnedest to change all that with the introduction of the POWERHOUSE line of solar shingles. As you'd expect, these solar shingles are aimed at roofers looking to tip their hats to Ma Earth while providing shelter for well-endowed homeowners, and unlike most of the futuristic alternatives, these actually look somewhat similar to traditional shingles. Dow claims that "affordability" will be a feature when they become widely available in 2011, but we're understandably skeptical of such a claim given just how pricey solar roofs currently are (and you know, considering the company's for-profit standing).

IBM's ultra-cheap DNA Transistor dream could lead to personalized medicines, confusion

Are you ready to get your nerd on? No, seriously -- are your rimmed glasses and pressed slacks at the ready? Good. IBM has just announced a full-on research project that intends to drive the cost of DNA sequencing down from millions of dollars to under $1,000. The reason? An ultra-cheap, silicon-based DNA Transistor could essentially "pave the way to read human DNA easily and quickly, generating advancements in health condition diagnosis and treatment." Moreover, it could eventually lead to personalized genome analysis and personalized medicines, meaning that your weekly dose of pills may literally have your name written on them. Just think -- with this breakthrough in place, you might just live long enough to see the Robot Apocalypse. Fun! Video's after the break.

Nobel Prize in Physics shared by CCD inventors, fiber optics pioneer


It's not every year that the Nobel Prize in Physics falls within our scope of coverage, but this year turned out to a big exception, as the Royal Swedish Academy of Sciences has deemed it fit to recognize two breakthroughs in the fiber optics and digital photography. The first of those (and half of the $1.4 million prize) goes to Charles K. Kao, whose work in the mid-60s getting light to travel long distances through glass strands made the fiber optic cables we have today possible. The second half of the prize is divided between Canadian Willard S. Boyle and American George E. Smith, who both worked at Bell Labs in Murray Hill, New Jersey, and invented the so-called charge-coupled device semiconductor, better known to anyone that has ever looked at a digital camera spec list as a CCD.

Video: OLED technology explained using a pickle and an Igor

Say bub, do you care to know what all that OLED jazz is about? We'll bet you do, but you don't wanna read some dry polysyllabic academic paper written by five guys during their time away from the lab. What you want is a sharp demonstration, preferably by an MIT professor, that goes straight to the point of what an Organic Light Emitting Diode is. Igor, roll in the pickle, please. Okay, he's not an Igor, his name is Vladimir Bulovic, but he does a terrific job of explaining how the passing of electric current excites organic molecules into creating those luscious ultra-bright colors we lust after that can fit inside ridiculously small spaces. Slide past the break to see the vid in full, and yes, it's just as weird as you think it'll be.

Time Telescope greatly improves optical data transmission, won't undo your past mistakes


Researchers at Cornell have developed a "time telescope" from silicon waveguides that work like the two lenses of a telescope (or microscope) to compress and decompress data. Using the method, they were able to shift a 24-bit light pulse from 2.5 nanoseconds to 92 picoseconds in length without losing any information -- delivering the it to its destination 27 times faster than traditional fiber optics. Of course, the current 24-bit limit is too small for real world use, but it is a start -- and since this uses industry-supported fabrication technology, there's a chance that we may actually get our hands on one of these things in the not-too-distant future. Insert your own Marty McFly joke here.

Carbon nanotubes find yet another purpose, could star in ultra-reliable batteries


Carbon nanotubes are kind of like peanuts. They both seem pretty simple at first glance, but with a little work, you can make pretty much anything out of 'em. Take this case, for example, as MIT boffins have discovered that by forming the tube-shaped molecules of pure carbon into minuscule springs, they could be "capable of storing as much energy, pound for pound, as lithium-ion batteries." The real kicker is exactly how they'd do it -- "more durably and reliably." Essentially, these newfangled cells could be left alone for years on end without losing their charge, and unlike conventional batteries, these wouldn't suffer from performance degradation when exposed to temperature extremes. Of course, anything as pie-in-the-sky as this is probably at least a decade or so out from Walmart shelves, but considering that the group responsible has already filed a patent, we'd say they're pretty confident in the possibilities.

Colored solar panels work without direct sunlight, double as PAR Can filters

With eco-friendliness on everyone's mind, it's no shock to see more and more progress being made in the realm of solar. Shortly after hearing that boffins across the way were swapping carbon nanotubes for silicon, a Tel Aviv-based startup is now hoping to push its colored panels into the mainstream thanks to their ability to work sans direct sunlight. Granted, the tinted cells have only shown a 12 percent efficiency rate in testing, but they can reportedly be produced for around half of what a conventional panel costs. In essence, the cost savings comes from the dearth of silicon within, as GreenSun Energy has discovered that power can be generated by simply diffusing available sunlight over the whole panel and allowing nanoparticles to handle the rest. We'll invite you to visit the links below for the science behind it, but we're just interested in helping Ma Earth while replacing every windows in our apartment with a stained glass alternative.
