Microsoft EMG Research Would Let Users Strong-Arm Gadgets Into Submission [Science]

Mind control is one way to control tomorrow's gadgets. Here's another equally cool, equally complex way: Controllers that involve nothing but the electrical impulses taking place everyday in our muscle tissue.

The system, developed as part of a patent filed by Microsoft, uses a series of connectors attached to an armband. The armband leverages Electromyography (EMG). As you can see in the video, this creates a system that translates the electrical activity found in our muscles into instructions for a computer. Or a Guitar Hero air guitar.

The system in the video is shown as a forearm version, but further patent reading reveals a completely wearable network of sensors that would adorn a user's head, arms and legs.

So air guitar and auto-trunks are only the beginning, although we'd need to be extraordinarily aware of our gestures and arm movements should a system become more mainstream, don't you think? I'd hate to flip a guy off on the highway and have my driver's side door pop open. [Muscle Computer Interfaces via Engadget]

Invetech 3D bio-printer is ready for production, promises ’tissue on demand’
Say hello to "the world's first production model 3D bio-printer." What you're looking at is a machine capable of arranging human cells and artificial scaffolds into complex three-dimensional structures, which result in such wonderful things as replacement liver and kidney tissue, or such simple niceties as artificially grown teeth. All we're told of the internal workings is that the bio-printer utilizes laser-calibrated print heads and that its design is the first to offer sufficiently wide flexibility of use to make the device viable. Organovo will be the company responsible for promoting the new hardware to research institutions, while at the same time trying to convince the world that it's not the fifth sign of the apocalypse. Maybe if the printer didn't have a menacing red button attached to it, we'd all be a little less freaked out by it.

Thorium, the Next Uranium [Science]

Wired has a fairly epic look into a material that could make nuclear power both clean and safe called thorium—named after the Norse god of thunder. Of course, scientists recognized its promise back in the 1950s.

Whereas uranium is extremely rare, requires purification and creates waste that will be with us for hundreds of thousands of years, thorium is extremely common, burns more efficiently in reactors and leaves less, less radioactive waste (that can't be turned into a nuke).

In fact, if it weren't for the Soviet Union building uranium reactors in the 60s (and us responding in typical Cold War fashion), we'd probably be using thorium today.

But as Wired explains, thorium may be poised for a comeback. [Wired and Image]

Invetech Delivers World’s First Production Human Tissue Printer [Medicine]

Or, as they call it, a "3D bio-printer." Essentially, it allows scientists to build tissue cell by cell. It's that cool sci-fi medical stuff we all dream about.

"Scientists and engineers can use the 3D bio printers to enable placing cells of almost any type into a desired pattern in 3D," Murphy said. "Researchers can place liver cells on a preformed scaffold, support kidney cells with a co-printed scaffold, or form adjacent layers of epithelial and stromal soft tissue that grow into a mature tooth. Ultimately the idea would be for surgeons to have tissue on demand for various uses, and the best way to do that is get a number of bio-printers into the hands of researchers and give them the ability to make three dimensional tissues on demand."

The system includes software that enables engineers to build a model of the tissue before layering cells with laser-calibrated print heads. So, it seems pretty similar to a standard 3D model printer. Hopefully, most of us will live to see the day when we can have new hearts and livers printed on demand. That would be handy. Teeth would be great in the short term too. That whole Polygrip lifestyle where corn cobs and apples could lead to disaster does not seem appealing. [Livescience]

Transparent Goldfish Developed By Japanese To Reduce Unnecessary Dissections [Science]

From the same land that transparent frogs were created in, comes the see-through goldfish. Japanese scientists hope that due to the organs and heart being visible, it'll eliminate the need to dissect them in schools and laboratories.

To be honest, I don't seem to recall slicing and dicing goldfish in biology class—but then, I was probably hiding in sickbay claiming vegetarianism. Perhaps goldfish dissections are more common in Japanese schools than anywhere else?

Anyway, the goldfish skin and scales lack pigment, which means all organs—including the heart and brain—are visible. Wonder when the same scientists will create transparent humans? [Scienceray]

Universe Ring’s Tiny Imperfection Is a Model of Everything We Know [Rings]

There can be only one Universe Ring. Unless you believe in the Multiverse. Then you can have as many as you want!

The Universe portion of this concept ring lies in the tiny dot. Within the dust particle-sized imperfection lies a tiny model. A model of what theorists like Stephen Hawking say our Universe looks like. You'll need some magnification to see it clearly, but it's there, inspired by scientists like Stephen Hawking and the anthropic theory.

Artist/creator To22 says the ring "puts our daily pursuits into perspective and reminds us that we are always a part of something bigger."

That's well and good and all, but I can seriously see this being used instead as a geek's dream wedding band. "I gave you the Universe, baby." Or something. Let me know if she/he says yes. [The Universe Ring via MAKE]

Mysterious Earth’s Core Plume Shifting the Magnetic North Pole [Science]

The north magnetic pole is moving at 37 miles-a-year toward Russia, which means they're stealing it. Or the Earth's core is fluxing. Actually, nobody really knows what's happening. I just hope it's not a prelude to a catastrophic magnetic shift.

Arnaud Chulliat—geophysicist at the Institut de Physique du Globe de Paris—says that there's a mysterious magnetic plume that is pushing the north pole at an increasing speed. The plume comes from deep in the Earth's core, says Chulliat, which is believed to be made of iron, with molten rock spinning around like a dynamo. This is what creates Earth's magnetic field. I have to admit that these theories sound a lot more logic that my theory of a malfunction in the giant sphere that powers our home planet—the one full of gargantuan unobtanium-powered machines created by Atlantis' scientists in 20,000BC—but whatever.

Meanwhile, regular scientists have evidence that the Earth's magnetic field flips every 300,000 years. The problem here is that 780,000 years have passed since the last polarity change, which means that a new shift could be imminent. There's proof that the field's strength is falling down at a very fast rate over the last two hundred years, a fact that has lead some experts to believe it could disappear completely over the next 1,000 years before it flips. Other boffins believe that this is just a fluctuation in the field.

If the first theory finally happens, the whole process will have catastrophic consequences to human civilization and nature. Without a magnetic field, nothing will protect us against space radiation. The weather will go completely gaga, and the Sun will fry all our communications and navigation services, not to talk about all of us. At the same time, countless migrational species will get lost, affecting food chains and causing mayhem through the entire planet.

Fun, huh? But fret not, my dear Earthlings, as this may not be related to the acceleration of the pole movement. The only thing we know for sure is that the magnetic north pole has been moving since 1904 northeastward at 9 miles a year, accelerating in 1989 until it reached its current 34 to 37 miles a year speed in 2007. Chulliat says that it's difficult to forecast when the pole will arrive to Russia, if it finally does.

Whatever the case is, this is yet another reminder that life may be even shorter than it already is, so stop surfing the web now, go out, and enjoy it. [National Geographic]

How to Make Your Baby a Genius: The Science Quilt [Science]

Now here's how to ensure your child's Nobel Prize. Babies might not understand the theory of relativity (or words even), but maybe this science quilt will have the little tot thinking early enough to get a jump-start on the competition.

I love the way that images representing atomic physics are laid on top fabric featuring dinosaurs riding in a wagon. It's what I imagine a quilt made by They Might Be Giants would look like.

Check out the link for the rest of the images. And good luck, kid. We're all expecting you to cure cancer now. No pressure. [Reddit]

Slo Mo Duck’s Corkscrew Penis Showcases the Majesty of Nature [Science]

Here is a slow-mo video of a scientist making a duck have sex with corkscrew-shaped beakers. It is one of the craziest things I've ever seen. Merry Christmas!

You're going to want to check out Carl Zimmer's full article about what exactly is going on here. Essentially, evolution has caused duck penises and duck vaginas to adapt into pretty wild and complex contraptions, with the penises unfurling into clockwise corkscrew shapes while the vaginas have evolved into counter-clockwise passageways with multiple pockets. And you thought your vagina was impressive!

Seriously, go check out the article to give this video some context. If nothing else, it'll provide you with a deeply inappropriate anecdote to tell your extended family over dinner tonight. [Discover Magazine]
