The End of Glasses? Eye-Shaping Contacts Might Cure Nearsightedness

techcrunch.com
Unless you’re a Hipster, eyeglasses are a major pain: kids wearing them get bullied, they’re expensive, they don’t play well with sports, and they can’t make up for perfect 20/20 vision. Finally, there may be a cure for nearsightedness (“Myopia”) on horizon. Biomedical scientist David Trolio has experimented with a...

Naval researchers soak up the sun below sea level with special solar cells

www.engadget.com
Have you ever harbored delusions of living in an underwater city inhabited by the likes of Ariel or those aliens from The Abyss? Yeah, well keep dreaming, because this engineering feat won't necessarily lead to that (the fictional mer people part, that is). What it will pave the way...

New Hybrid Solar Cells Harness More Of The Sun’s Light Spectrum

techcrunch.com
Scientists at the University of Cambridge in the UK have found a way to improve the efficiency of photovoltaic cells by as much as 25% through harnessing more of the sun’s spectrum than most traditional silicon-based solar cells can. The new design, developed at the university’s Cavendish Laboratory in the...

Embrace the light! Researchers built all-optical device for faster broadband

gigaom.com
Researchers at the University of Minnesota have built an all-optical device that is able to flip a switch. The technology might strike many as esoteric, but getting light to change state (from on to off) based only on a signal from another light is a big deal that could pave...

The first quantum entanglement of photons through space and time

www.extremetech.com
Ready for a mind-bending news story that will forever change your perception of life? Quantum physicists in Israel have successfully entangled two photons that don't exist at the same time. They create one photon and measure its polarization, destroying it -- they then create another photon, and though it never...

Scientists create the first universal quantum network, are scared to restart the router

www.engadget.com
We all know that most networks are, well, just not "quantumy" enough. Good news, then, that German boffins at the Max Planck Institute of Quantum Optics have created the first "universal quantum network." We've been hearing about plain old quantum computing since the first qubit was sent, but now we...

Xbox One: Watch the new Kinect detect a heart rate from across the room

www.geekwire.com
Microsoft has significantly upgraded the sensing capabilities of the second-generation Kinect sensor that will ship with the newly announced Xbox One game console. One example: The Kinect can detect a user’s heart rate optically. See the video above for a demonstration of the capability during a tour of the...

This Camera Can See Around Corners

www.businessinsider.com
This camera can see actually see around corners by scattering a laser pulse and reassembling photons as they return to the lens, reports Nature. It looks a little elementary at the moment, but military and security applications seem most obvious. Check out this very accessible video for a more...

The devices we carry around tend to evolve much quicker than energy sources inside them. If you need proof of that, just look at the ubiquitous lithium ion battery, which has seen little improvement for over a decade. That may all change within the next few years with advances...

A Schrödinger cat with eight lives: quantum entanglement of eight photons

arstechnica.com
One of the most mind-blowing areas of quantum mechanics is entanglement: two or more particles separated in space can have physical properties that are correlated. A measurement performed on one particle will tell us the result of the same measurement taken on an entangled particle. Entanglement is important but...

Quantum teleportation achieved over ten miles of free space

arstechnica.com
Quantum teleportation has achieved a new milestone or, should we say, a new ten-milestone: scientists have recently had success teleporting information between photons over a free space distance of nearly ten miles, an unprecedented length. The researchers who have accomplished this feat note that this brings us closer to...

Chinese scientists claim that they have teleported material over a distance of ten miles with 89% fidelity: Teleportation over distances of a few hundred meters has previously only been accomplished with the photons traveling in fiber channels to help preserve their state. In this particular experiment, researchers maximally entangled two...
