invisibility cloak

3D-print your own invisibility cloak, kind of

While we remain dubious about the legitimacy of using the word "invisible" when visible light isn't involved, that's what a team of engineers at Duke University have dubbed their creation. Seven years ago, they demonstrated their first "invisibility cloak" in a laboratory; now, thanks to 3D printing, the fabrication process is a lot more accessible.

The object -- which looks more like a Frisbee made of Swiss cheese than a wearable cape a la Harry Potter -- has a large hole in the center, with seemingly random holes in the disc. The size, shape, and placement of these holes have actually been determined using algorithms to disguise any object placed in the center hole from microwave beams aimed through the side of the disc, making it appear as though the object isn't there. … Read more

Scientists claim they made event invisible

Think of all the things you wish you'd never seen happen.

Your auntie making that speech at Thanksgiving dinner about birds, bees, and Bieber. Your lover accusing you of infidelity with an alien. Every last minute of "From Justin to Kelly."

Well, now some very clever Cornell people want to offer you hope, mingled with fact.

Research published in Nature magazine, helpfully translated by the Associated Press, declares that these scientists successfully managed to time-cloak an event--so that, to naked and disbelieving eyes, it never happened.

They say they did it by interrupting the light flow in … Read more

Picture this: Invisibility cloak made from glass

Once or twice a year, we bring all you "Harry Potter" fans news of yet another invisibility cloak under development. So it is that we return with word of another scientist promising to help you perform your wizardry in secret.

This time, it's Elena Semouchkina who's venturing into H.G. Wells territory. An associate professor of electrical and computer engineering at Michigan Tech University, Semouchkina has found a way to use magnetic resonance to route rays of light around objects, making the objects undetectable by the human eye.

Other researchers have bent visible light using things … Read more

Cloak of invisibility becomes more foreseeable

It came too late for Jesse James. There was a time, indeed, when John Edwards might have found it very useful, but that time has surely passed.

In life, timing is everything. So while researchers at Karlsruhe Institute of Technology in Germany claim that they have made a breakthrough in invisible-cloak technology, there are far too many mortal souls who can only wish that they would hurry up.

According to the Associated Press, the German scientists managed to successfully hide from greedy eyes a tiny bump in a layer of gold.

When I say "tiny," I mean 0.… Read more

The 404 412: Where we celebrate Halloween in August

Alli (aka Heavy from the old days) joins us on today's show and as usual, she brings up the wackiest topics. Today's tangents include Halloween costume ideas, time travel, and super powers...oh, and some stories from the Internet, too!

We always love having Alli on the show because she always brings up the weirdest topics of discussion. Case in point: Halloween costumes...it's the end of August! It's going to be hard to top last year's costumes but Alli has a great idea for a DOUBLE costume: Jon & Kate Plus 8--it's the perfect costume for us, aside from the fact that we'd have to stand next to each other all night and somehow abduct eight babies. This might be our last Halloween.

Next, we move onto a rundown of 10 joke technologies that sort of became real, but we actually only get into the invisibility cloak before getting sidetracked into our most desired super power. Jeff wishes he had the power to tan, I go with the ability to morph into a potted plant, and Alli just wishes she could get out of The 404 studio.

Plenty of more stories to get to, but don't just read about them here, listen to the show! We've got Bob Dylan voicing a GPS system (replete with our awful impersonations), the UK's disturbingly graphic "texting while driving" PSA, and Microsoft's tasteless Photoshop incident. You don't want to miss this episode!.

Buzz Out Loud 785: Don't cross the Olympic streams

We tried to give NBC the benefit of the doubt when it comes to Olympic streaming, but then we tried it. And it's ridiculous. Also, we wonder if the iPhone makes you fat, even as it fattens Steve Jobs' wallet. We also discuss the technicalities of invisibility cloaks, and opt-out of Obama's aggressively hip Internet outreach campaign.

Invisibility cloak on the horizon, scientists say

Scientists say they are a step closer to developing materials that will render people and other objects invisible.

Researchers say they can redirect light around 3D objects using metamaterials--artificially engineered structures created at a nano scale that contain optical properties not found in nature, according to an Associated Press report.

People see objects as a result of the light reflecting or scattering off them. This new mixture of materials has "negative refractive" properties that keep light from being absorbed or reflected by the object, allowing only the light from behind the object to be seen. Essentially, the material … Read more
