Samsung took the leap and delivered Quantum Dot TV ahead of the competition and now they’ve setting their eyes on something more revolutionary: Holographic TV.

Engineers from the University of California, San Diego have brought together a couple of nascent technologies that could result in inexpensive and long-lasting electronic devices. The team created a magnetic ink that can print a variety of self-healing components.
The ink is loaded with inexpensive microparticles made of neodymium that are magnetically oriented in such a way that if the material rips, each side of the tear is attracted to the other. This allows components printed with the ink to self-repair tears as wide as 3 mm, which the researchers claim is a new record.
We’ve seen similar properties in boron nitride nanosheets that can repair themselves even after being cut in half, but that material doesn’t conduct electricity. Batteries have been developed that can be self-repaired when they rupture in a similar fashion and other components have been implanted with capsules that rupture when cracks develop in the circuits, releasing a liquid that fills in the crack and dries instantly to restore conductivity.

In a development beneficial for both industry and environment, UC Santa Barbara researchers have created a high-quality coating for organic electronics that promises to decrease processing time as well as energy requirements.
“It’s faster, and it’s nontoxic,” said Kollbe Ahn, a research faculty member at UCSB’s Marine Science Institute and corresponding author of a paper published in Nano Letters (“Molecularly Smooth Self-Assembled Monolayer for High-Mobility Organic Field-Effect Transistors”).

Since the arrival of flat-screen TVs, there’s not been a whole lot to get excited about in the world of televisions — how many ways can you improve on a big slab of glass, after all? Well, how about by making it almost invisible when you’re not using it?
That’s the thinking behind a new prototype from Panasonic that’s just been shown off at the CEATEC electronics expo in Japan this week. When switched on, it’s just like a normal TV. When switched off, it’s as transparent as glass, meaning you can see the wall or shelving behind.
Panasonic describes it as the “future of display screens” — although as you might expect, the company’s staying tight-lipped about the technology behind its transparent TV, just in case its competitors have something similar in mind.

I said on here the other day about TV’s that would turn into windows.
Panasonic showed off a prototype version at the CES technology conference this year, but it used LED technology, and the screen was so dim it had to be underlit to work.
The new version is bright and clear — coming to life with the press of a button or the wave of a hand.
A Panasonic spokesperson said that the technology was still in development, and that ‘transparent’ TVs were unlikely to hit the market for three years at least.

The majestic auroras have captivated humans for thousands of years, but their nature – the fact that the lights are electromagnetic and respond to solar activity – was only realized in the last 150 years. Thanks to coordinated multi-satellite observations and a worldwide network of magnetic sensors and cameras, close study of auroras has become possible over recent decades. Yet, auroras continue to mystify, dancing far above the ground to some, thus far, undetected rhythm.
Using data from NASA’s Time History of Events and Macroscale Interactions during Substorms, or THEMIS, scientists have observed Earth’s vibrating magnetic field in relation to the northern lights dancing in the night sky over Canada. THEMIS is a five-spacecraft mission dedicated to understanding the processes behind auroras, which erupt across the sky in response to changes in Earth’s magnetic environment, called the magnetosphere.
These aurora images were taken in 2013 from the ground looking up with a network of all-sky cameras spread across Canada, studying auroras in collaboration with THEMIS. Taking images of aurora from the ground in conjunction with satellite data taken from above the atmosphere gives scientists a more comprehensive picture of how and why auroras form.

Read more China receives first data from unique ‘hack-proof’ quantum satellite The first Chinese quantum radar was developed by the Intelligent Perception Technology Laboratory of the 14th Institute in CETC, according to Xinhua news agency. CETC stands for Electronics Technology Group Corporation, a defense and electronics firm.
The radar was tested in mid-August, Xinhua said in a Thursday report.
The system was able to detect a target at a range of 100 kilometers in a real-world environment, the report said. The device employs single photon detection technology.
