Analog tape disks degrade, digital storage media is temperature-sensitive, and books (print on paper) are still some of the best ways to store data long-term, at least until five-dimensional storage came along to change all of that, jumping us from centuries to eons in scope.

Researchers at the University of Southampton’s Optical Research Center have developed a 5D storage technique that can keep data safe for billions of years, etching it onto thermally-stable discs with femotsecond laser bursts. Think: Superman’s memory crystals, except real.

The medium can hold a stunning 360 terabytes per disc and withstand temperatures of up to 1,000 degrees Celsius, but kept in ideal conditions have a shelf life of 14 billion years. Human-readable etchings at larger scales allow the discs to be marked for future identification.

The trick is in the layering of nanoscale dots, defined by three points in space as well as their size and orientation, constituting their fourth and fifth dimensions. Light traveling through the disc is read with a polarizer. In the past three years, the team has upped the storage capacity from a few hundred kilobytes to its currency status.

“It is thrilling to think that we have created the technology to preserve documents and information and store it in space for future generations,” Professor Peter Kazansky from the ORC said in a statement. “This technology can secure the last evidence of our civilisation: all we’ve learnt will not be forgotten.”

Using ultrasonic arrays to create pressure on users’ hands, this new approach to telehaptic holography allows people to touch and feel at a distance, sharing an enhanced holographic experience way beyond virtual reality.

Aerial imaging panels in the “Haptoclone” system create the visual portion of the shared illusion, which can be experienced simultaneously by different users around the world.

A Kinect sensor translates motions by both users in realtime responses, moving holographic objects in shared three-dimensional spaces and emitting pressure accordingly.

“It would be great to allow people in different locations to communicate with one another while experiencing a sense of touch. We could, for example, put a transparent glass here and divide the room,” explained researcher Yasutoshi Makino. “Imagine if you were in a zoo, and there was a lion on the other side of the glass that you could have the sensation of touching.”

For now, there remain significant limitations, particularly when it comes to the ultrasonic pressures applied – there are safety limits keeping those sensations from being as complete as they might be in reality. So while you can toss a ball back and forth, bear hugs may be a ways off yet.

Arthur C. Clarke’s idea that “Any sufficiently advanced technology is indistinguishable from magic” has been cited by laymen for decades to explain the seemingly unexplainable. But now, a piece of technology exists that even scientists can’t really wrap their heads around. British scientist Robert Shawyer created a space engine that requires no propellant and can keep going indefinitely, provided the hardware doesn’t suffer any damage. It’s what the scientific community would call impossible. The rest of us might be inclined to call it magic. Recently, NASA confirmed that this “impossible” engine actually works.

The EmDrive converts microwaves into thrust via a mechanism that can’t quite be explained by conventional physics. Microwaves are generated with electricity which could be provided by solar power; these microwaves then bounce around in a closed container, somehow providing thrust that requires no propellant at all. In Shawyer’s experiments – and in a subsequent Chinese experiment which validated Shawyer’s results – enough thrust was produced to operate a standard satellite thruster. (The above video is Shawyer’s EmDrive moving itself during a 2007 test.)

Shawyer and the Chinese team had achieved the impossible, but no one believed their findings. Shawyer tried for years to get someone in the scientific community to take his work seriously, but it wasn’t until American scientist Guido Fetta built his own propellant-less microwave thruster that people started to pay attention. Fetta worked with NASA’s advanced propulsion team to test the microwave thrust method and, to everyone’s astonishment (except Shawyer’s, of course), found that it worked. The success of the experiment flies in the face of the law of conservation of momentum, making it unexplainable by conventional physics. The team even made modifications to the design that should have made it fail, but somehow it still worked. NASA’s version only produced a tiny fraction of the power that Shawyer’s EmDrive achieved, but the fact that it produced any thrust at all has been enough to draw the attention of the worldwide scientific community.

NASA’s paper on the experiment doesn’t go into much detail about the actual mechanism that makes this seemingly-impossible engine work. They do, however, hint at the possibility that the force is produced by interacting with the quantum vacuum virtual plasma. In other words, the engine could be using quantum mechanics which we can’t quite explain just yet. If true, the EmDrive (or the Cannae Drive, as Fetta calls his version) could be the most incredible breakthrough in the history of space travel. The need for on-board propellant is probably the biggest hurdle in deep space exploration, and a propellant-free engine that could theoretically travel forever could make it possible for us to venture farther from Earth than conventional physics would ever allow.

What would you give – particularly on those stressed-out mornings when you’re running late – to be able to charge your smartphone in a mere half minute? An Israeli startup called StoreDot has developed a prototype that does exactly that, even if the battery is completely dead.

The secret used in the amazing charger is called quantum dot technology. It relies on microscopic nanocrystal batteries made of semiconductor materials. StoreDot calls their version of the technology “nanodots,” and they hope to completely change the world of mobile device batteries. The technology is much greener than current mobile batteries and, amazingly, also costs less.

As of yet, as seen in the video above, the StoreDot device is big and bulky, and nowhere near ready to be used in a phone. But the external charging capabilities are enough for us – we’d love to get our hands on a prototype, no matter how clunky and cumbersome it might be. According to StoreDot, we’re about a year away from seeing this technology built inside phones, and another two years away from seeing it get powerful enough to last a whole day. By 2017 or so, we should all be carrying around smart devices with quantum magic happening inside them.

Aircraft anti-detection systems have gotten incredibly complex. So complex, in fact, that they can intercept a radar signal and send back a picture of something other than the aircraft (see the images below). Researchers at the University of Rochester in New York have figured out a better way to outsmart the outsmarters by exploiting the quantum properties of photons. Attempting to measure a photon always destroys its quantum properties, so the team posited that they could shoot polarized photons at aircraft to create images of the craft.

If an enemy were to intercept those photons and send them back in a deceptive pattern to indicate that the measured object is a different shape or in a different location, it would be immediately obvious. This is because the act of manipulating the photons would always change their delicate quantum properties. As seen in the sample images above, a manipulated image is simple to detect thanks to the high rate of polarization errors in the returned signal. The system isn’t flawless as there are still ways for very savvy adversaries to crack it – but there are also ways to fix those vulnerabilities.
