NC State’s coiled nanowire discovery could lead to stretchable electronic devices

Cotton may very well be the fabric of our lives, but it’d sure feel a lot better draped across our skin if we could incorporate stretchable electronic devices into it. That’s the goal of NC State’s own Dr. Yong Zhu, who has worked with a team of gurus to create “the first coils of silicon nanowire on a substrate that can be stretched to more than double their original length.” Essentially, this type of breakthrough brings us one (major) step closer to “incorporating stretchable electronic devices into clothing, implantable health-monitoring devices, and a host of other applications.” Compared to prior studies on buckling, this particular approach one-ups those focusing on freestanding nanowires, with the new coils’ mechanical properties enabling them to be “stretched an additional 104 percent beyond their original length.” That’s a lot of technobabble, for sure, but what you need to realize is just how amazing your life will be as soon as The Zhu Crew figures out how to improve the reliability of the electrical performance when the coils are stretched to the limit. Flexible PMPs woven into your ski jacket? Bendable LCDs sewn right into your car’s headrests? The future… it’s here.

Study shows love for music relates to brain chemical, not to My Chemical Romance

It would make sense that people listen to music for the sheer pleasure of it, right? That’s what we thought, but apparently there’s a scientific reason for this. Scientists have discovered that when Earthlings listen to pleasurable music, one particular chemical is loosed in the gord. The study, conducted by Robert Zatorre and Valorie Salimpoor of McGill University in Montreal, concluded that when the participants tuned into instrumental pieces they were familiar with, their brains released dopamine into the striatum — an area of the noggin linked with anticipation and predictions. According to PET scans, the members of the study unleashed the chemical 15 seconds before a climaxical moment in a song, signaling the possibility that humans may actually release it in anticipation and not as a reaction to a wailing solo. Bonus point? Chopped and screwed tracks unleashed forty times more dopamine. Just kidding, but it’s probably true.

4G Shocker! Study finds consumers want what they fail to understand

We’ve certainly seen our fair share of 4G devices in the Las Vegas sun (well, convention center) this year, but as you might have guessed, a recent study finds that increased awareness does not necessarily equal increased understanding. As the Nielsen Company recently discovered, the majority (54 percent) of consumers who know or care about 4G were relying on the old International Telecommunications Union definition of mobile data speeds over 100 Mb/s, even though carriers have sort of been making up their own rules (for instance, T-Mobile and AT&T are calling their HSPA+ networks 4G). And what to make of the large percentage of people who think that 4G somehow refers to the iPhone 4? That one’s a perpetual head-scratcher. But in the end, the study finds that none of that really matters: almost three in ten consumers are gearing up to buy a 4G device within the next twelve months. And \that’s what really matters, right?

Late mid-week shocker: young adults get their ‘news’ from the ‘net, not from television

In what is undoubtedly a shocking and groundbreaking revelation, the Pew Research Center has conducted a recent study which has caused it to conclude that young adults now get their news predominantly from the internet, rather than from television (and even less from ham radio). According to the study, which the center seems to have been conducting yearly for a while now, 67 percent of adults under 30 said in 2010 that the ‘net was their primary source of news, up from 34 percent in 2007. Curiously, respondents could choose up to two ‘main’ news sources, so 52 percent report that television is a main news source in 2010, down from 68 percent in 2007. While none of this probably comes as any surprise to any of you, our readers, it does tend to explain that strange and ever-growing tendency we’ve noticed in our friends of talking about things like Groupon, Facebook, and some meme some webpage made up to sell something as if they were talking about actual news.

Shocker! Media addicts suffer withdrawal symptoms, just like real addicts

…and we’re all media addicts, aren’t we? A recent study conducted by the International Center for Media & the Public Agenda (ICMPA) certainly seems to indicate that this is indeed the case. The premise was pretty straightforward: students at twelve universities around the world were instructed to abstain from using all media for twenty-four hours. The results were somewhat predictable: across the board, going without television was somewhat easy to do, while abstaining from text messaging and instant messaging brought on withdrawal symptoms: “When I did not have those two luxuries,” wrote one student, “I felt quite alone and secluded from my life. Although I go to a school with thousands of students, the fact that I was not able to communicate with anyone via technology was almost unbearable.” According to Dr. Roman Gerodimos of the University of Portsmouth both psychological and physical symptoms were reported by the young techno-junkies.

This is your brain. This is your brain on video games

Sure, you’ve probably seen countless scientific studies involving video games — but have you have you ever wondered what your brain actually looked like while your playing video games? Well, feast your eyes on the image above. That’s an MRI scan of New York Times writer Matt Richtel’s brain that was captured while he played a simple driving game — all in the name of science (and journalism), of course. As Richtel notes, however, that’s just one example of the ways researchers are using such technology to “map the ethereal concept of attention,” and scientists have turned up some other interesting findings as of late. Researchers at the University of Utah, for instance, have found that people’s ability to juggle two tasks begins to drop off in their 30s and then sharply drops in their 40s, which contradicts earlier suspicions that people’s ability to multitask only began to degrade when they’re much older. Some other researchers are still suspicious of those findings, however, and Dr. Gazzaley of the University of California at San Diego is quick to point out that all of this research is still in the earliest stages — he’s expecting some more detailed findings next year when his team expands their tests and begin to incorporate EEG monitoring as well.

Lightning photographed by superfast X-ray camera, Nikola Tesla nods with approval

You know, we could just leave you with the image above and be done here, but its backstory is almost as cool. Researchers at the Florida Institute of Technology have built a 1,500-pound X-ray camera that can shoot ten million frames a second and then pointed it at a nearby flash of lightning to try and learn more about it. How did they know where the lightning would strike? Well, in true scientific fashion, they caused it themselves! This was done by shooting rockets into thunderstorms, with attached wires directing the flow of energy down into their target zone. The imagery produced from the X-ray sensor is actually extremely low-res — a 30-pixel hexagonal grid is all you get — but it’s enough to show that X-ray radiation is concentrated at the tip of the lightning bolt. What good that knowledge will do for the world, we don’t know, but we’re sure it’ll provide nice fodder for the next round of superhero empowerment stories.

Stereoscopic copy-paste finally brings that clone tool into the third dimension (video)

Stereoscopic copy-paste finally brings that clone tool into the third dimension (video)

With the right software anybody can be photo editing guru, eliminating redeye, removing unsightly blemishes, and maybe adding an image of Godzilla lurking in the background just for fun. However, if you’ve been unlucky enough to try to do the same in 3D you know just how distinctly unsatisfying that experience can be. Maybe not for long. Thanks to NewScientist we just caught a glimpse of an October presentation made by Swiss engineers Joren van Baar and Wan-Yen Lo called “Stereoscopic 3D Copy & Paste.” It is, basically, exactly what it sounds like, tools that let you define various objects and planes on a stereoscopic image, similar to how you might grab a shape with the magic wand tool, and then duplicate it and move that shape around on both parts of the 3D photo. The software handles re-creating shadows, automatically tackling occlusion too, and while the results aren’t perfect, particularly if you’re trying to change perspective or partially occlude an object behind something that’s transparent, it certainly trumps trying to do it by hand. Check out the video below and take a moment to be thankful that you didn’t have to buy gifts for all those kids above.

New solar machine could generate hydrogen fuel, food for your future vehicle

We’re hesitant to file this one in the folder marked “Awesome Things That’ll Never Happen,” but it’s definitely on the watch list. A new prototype solar device has been concocted to convert sunlight into fuel, much in the same way a plant does. Eco-minded folks will probably understand that conventional photovoltaic panels “must use the electricity they generate in situ,” and thus, cannot deliver energy at night; this here device takes a rather unorthodox approach, using the sun’s rays along with ceria (a magical, marvelous metal oxide) to “break down carbon dioxide or water into fuels which can be stored and transported.” In theory, at least, the device could be used to create hydrogen and / or carbon monoxide, with the former being obviously useful for fueling up hydrogen-based cars of the future. Sadly, the existing prototype is horribly inefficient — only around 0.7 percent of the solar energy can be converted into fuel — but researchers are adamant that they can boost that to nearly 20 percent in time. We’ll check back in a decade or so to see how things are progressing.

Visualized: world’s largest neutrino observatory rivals Guatemala sinkhole

Without question, one of the images from 2010 will be the insane, almost incomprehensible sinkhole that emerged in Guatemala earlier this year, but this particular shot from the South Pole does an outstanding job of vying for equal attention. Coming directly from the University of Wisconsin-Madison, this is a look into the planet’s largest neutrino observatory, which was just completed after half a decade of work with $279 million. The goal? To detect “subatomic particles traveling near the speed of light,” and when you have an ice-bound telescope that encompasses a cubic kilometer of Antarctic ice, well… you’ve high hopes for success. Will this pipe into the underworld finally lead us to understanding Dark Matter? Will century-old mysteries of the universe finally have answers? Even if not, we’re envisioning a heck of an entry fee when it’s converted into the world’s longest firehouse pole and marketed to affluent tourists who make the trip down.
