Submission + - Nanoresonators create ultra-high-res displays (linuxfordevices.com)

TuurlijkNiet writes: Eat your heart out, 'Retina display'. A new technology unveiled yesterday will allow creating pixels eight times smaller than the ones on Apple's iPhone 4, eliminate the need for polarizer layers, and allow screens to make much more efficient use of available light, say University of Michigan researchers. The pixels in the nanoresonator displays are about ten times smaller than those on a typical computer screen, and about eight times smaller than the pixels on the iPhone 4, which are about 78 microns, according to Guo. Such pixel densities could make the technology useful in projection displays, as well as wearable, bendable or extremely compact displays, according to the researchers.

Submission + - China Unveils Plans to Mine the Yellow Sea Floor (china.org.cn)

eldavojohn writes: Details are limited but state media is reporting on $75 million being put into a new research facility in Qingdao, Shandong Province that will conduct research into mining the sea floor. From the article, 'Scientists believe sea beds at a depth of 4,000 to 6,000 meters hold abundant deposits of rare metals and methane hydrate, a solidified form of natural gas bound into ice that can serve as a new energy source.' The research center's first goal is to do surveying and exploration with a new submersible named "Jiaolong" (a mythical aquatic Chinese dragon). Hopefully these quests yield energy resources to curb growing demand for resources like liquefied coal in China.

Submission + - Ask Slashdot: Best video surveillance system 1

An anonymous reader writes: I need an inexpensive video surveillance system (about four fixed cameras and one PTZ) which i can control it through the Internet. It must work for a distance of over 30 m (100ft) both day and night and it must be compatible with a Linux server. What do you recommend me to use?

Submission + - iPad tactile object recognition system (geek.com)

An anonymous reader writes: The guys over at the Volumique blog have a different idea as to how to tackle apps for Apple’s devices. They aren’t just thinking about a digital activity on such devices, they are experimenting with using physical objects through Apple’s multi-touch screens.

Imagine being able to buy the playing pieces for a board game, but then loading up an app on your iPad for the actual board. The pieces would be recognized when placed on the iPad’s screen, it would even recognize which direction they were facing. This may sound like an impossible feat unless you use a much more expensive device like Microsoft Surface, but Bertrand Duplat and Etienne Mineur at Volumique already have it working.

Submission + - 1 Molecule Computes 1000s Times Faster Than PC (popsci.com) 1

alexhiggins732 writes: A Single Molecule Computes Thousands of Times Faster than Your PC

A demo of a quantum calculation carried out by Japanese researchers has yielded some pretty mind-blowing results: a single molecule can perform a complex calculation thousands of times faster than a conventional computer.

A proof-of-principle test run of a discrete Fourier transform — a common calculation using spectral analysis and data compression, among other things — performed with a single iodine molecule transpired very well, putting all the molecules in your PC to shame.

GenThrift writes: Model air plane enthusiast captures criminals with home made drone survailance "A MODEL aeroplane equipped with a camera has inadvertently captured graffiti artists at work in the southern suburbs, leading to their arrest.The aerial surveillance was carried out over the Aldinga Bay Surf Life Saving Club in March by an model aircraft enthusiast using what police described as a "slow -flying electric remote-controlled aeroplane".The modified aircraft was rigged with a camera, attached with a rubber band, which had been set to capture images every 1.5 seconds.The images proved much more interesting than the plane owner was expecting — they captured graffiti vandals at work.The plane operator sent the pictures to South Coast police who used them to identify the alleged offenders." http://www.news.com.au/adelaidenow/story/0,22606,25480726-5006301,00.html
