Scientists demonstrate unjammable radar based on quantum imaging
Author: Stacey Cook
Unfortunately for those in the opponent monitoring game, advanced aircraft-equipped anti-detection systems could outfox radar by intercepting the signal and sending back an untrue image, as revealed above. Nevertheless, specialists from the University of Rochester have figured out a technique to beat such a jamming system that harnesses the quantum properties of light. By polarizing photons prior to delivering them to objects to be scanned, any attempt at modifying the returning photons triggered quantum disturbance that was simple to spot, in the form of the extremely high polarization mistakes received the second untrue image. According to the group, such a a system can “effortlessly be recognized and integrated into contemporary optical varying and imaging systems,” with a little work, making it considerably harder to beat radar systems. Inspect the source for even more “light” reading, provided that quantum mechanics does not break your brain.

Researchers demonstrate world’s first mind-controlled robotic legs
Author: Jamie Colby
Specialists at the Long Coastline Veterans Affairs Medical Center and the University of California, Irvine have successfully shown a pair of robotic legs controlled by the user’s mind, possibly opening the door for brand-new sorts of smart prostheses for paraplegic individuals. Presenting their outcomes in a paper posted on arXiv, they explain how the unit utilizes a cap to measure EEG signals from the brain, translating them into bodily movements.
While future improvements might enable the user to change speed and direction and perform actions such as sitting down and standing up, the existing execution of the system is only capable of alternating between binary “idling” and “walking” states. Another issue is so-called “false …

Leaked Windows 8 pre-beta install screenshots demonstrate theme color picker
Author: Mark Jeffries
- Windows 8 color picker
Screenshots of a near final copy of Windows 8 beta leaked to the Internet over the weekend.
The screenshots demonstrate a number of setup customisations available in the beta version of Windows 8. Theme colors for the Windows 8 Start Screen experience can be selected prior to install and it appears most of the colors on the slider are dark blue, pink, green and purple variants. Win8china posted the screenshots over the weekend.
Little is known about the feature set of Microsoft’s Windows 8 beta. Recently leaked screenshots indicate that Microsoft will allow users to change the Start Screen color and the Start Screen background image in beta copies of Windows 8. Microsoft has previously detailed some other minor improvements to the Windows 8 beta. Users will be able to create, name and rearrange Start Screen groups as well as navigate with the Windows 8 Apps screen in a better way. Microsoft is planning to group applications to make it easier for users to identify them in Windows 8 beta. Windows Media Center will also return to Windows 8 beta alongside the typical Windows games, DVD creator and .NET 3.5. All were missing from the developer preview, made available in September.

Chinese scientists demonstrate 2Mbps internet connection over LED
Author: James Cliff
LED data transmission used to be all the rage — we fondly remember beaming Palm Pilot contacts via IrDA. Then we got omni-directional Bluetooth and building-penetrating WiFi, and put all that caveman stuff behind us. But now, scientists the world over are looking to bring back line-of-sight networking, and the latest demonstation has Chinese researchers streaming video to a laptop with naught but ceiling-mounted blue LEDs. The Chinese Academy of Sciences claims to have realized a 2Mbit per second internet connection that transmits data simply by modulating the flicker of the little diodes, and imperceptibly enough to have them serve as room lighting as well. Like Boston University before them, the Chinese scholars see short-range LED networks controlling smart appliances as well. It’s not quite the gigabit speed you’d get from laser diodes, but this way you’ll get more mileage out of those expensive new bulbs.
