Quantum Teleporter:

Q-Teleportation has been successful on smaller objects according to a Study. “We were able to perform a quantum teleportation experiment for the first time ever outside a university laboratory,” said Rupert Ursin, a researcher at the Institute for Experimental Physics at the University of Vienna in Austria. In q-Teleportation it is the quantum states of the objects that are destroyed and recreated, and not the objects themselves. Therefore, q-Teleportation cannot teleport animate or inanimate matter (or energy) in its physical entirety. The device thus creates a replica of an original thing  at a new position and the original thing ceased to exist once the replicas were created. (via National Geographic.)

360º 3-D Holographic Displays:

The ZCam^TM is a video camera that can capture depth information (which is used to build the 3D model) along with video and is produced by 3DV Systems. The technology is based on the Time of Flight principle. In this technique, 3D depth data is generated by sending pulses of infra-red light  into the scene and detecting the light reflected from the surfaces of objects in the scene. Using the time taken for a light pulse to travel to the target and back, the distance can be calculated and used to build up 3D depth information for all objects in the scene.

Nano Firefly:

Light things without electricity?:

Fireflies light up summer lawns at dusk through chemical reactions, which take place between a light-emitting substance and its related enzyme. Luciferin and luciferase, respectively, could provide a natural, electricity-free glow for ambient lighting and other uses. But previous experiments to this end have not yielded very bright light.

Now researchers at Syracuse University have a new method for capturing firefly light, by using nanorods doped with luciferase. The resulting system is 20 to 30 times more efficient than other attempts at producing bright light, they say. Future Christmas light displays, night-lights and other dim but decorative lighting made with this method wouldn’t need any batteries or electrical outlets to shine brightly.

The trick was changing the scope of the interactions between the luciferin and the luciferase, according to Mathew Maye, assistant professor of chemistry at Syracuse. The team attached genetically modified luciferase to a core of nanorods made from cadmium-based semiconductor material. These are similar to quantum dots, but in this case they’re quantum rods. Then the researchers added the luciferin, which serves as a fuel for the fiery glow. When the chemicals interact, they release energy, which is transferred to the nanorod. That’s what actually makes the nanorod glow.

The researchers found that changing the size of the nanorod core, as well as lengthening or shortening the rods, can produce new colors. Where fireflies can only produce that trademark yellowish glow, this nano-device can produce hues of green, red and orange, even producing infrared light.

The team still needs to study how to transfer more energy to make the glow last longer, and how to make the system work on a larger scale. But it could conceivably work in lighting displays, they say. The research appears in ACS Nano Letters.

Bionic Eye:

A new bionic eye implant could allow blind people to recognize faces, watch TV and even read. Nano Retina’s Bio-Retina is one of two recent attempts to help patients with age-related macular degeneration, which affects 1.5 million people in the U.S. Although a similar implant, Second Sight’s Argus II, has been on the market in Europe since last year, it requires a four-hour operation under full anesthesia because it includes an antenna to receive power and images from an external apparatus. The Bio-Retina implant is smaller because it doesn’t have an antenna. Instead, the implant captures images directly in the eye, and a laser powers the implant remotely. Because of Bio-Retina’s compact size, an ophthalmologist can insert it through a small incision in the eye in 30 minutes—potentially more appropriate for seniors. The Bio-Retina will generate a 576-pixel grayscale image. And clinical trials could begin as soon as next year.

1. DON GLASSES

Ordinary-looking glasses contain a battery, a power-delivering laser apparatus and working lenses (to help with vision problems such as nearsightedness and astigmatism).

2. SHINE LASER POWER

The near-infrared laser beam, gentle enough to shine harmlessly through the eye onto the implant, provides up to three milliwatts of power to a photovoltaic cell on the eye implant. The light is invisible, so it won’t interfere with sight.

3. CAPTURE IMAGE

Photoreceptors pass light information to an image processor that translates each image pixel into a series of electrical pulses that represent a particular shade of gray.

4. TRIGGER NEURONS

(Inset) Six hundred needle electrodes (wrapped in biocompatible silicon and sapphire to prevent the formation of scar tissue) penetrate the retina. Each electrode represents one pixel, sending pulses of electricity to stimulate the eye’s neurons, which transmit the image to the brain.
