'Time reversal' allows wireless broadband under the sea
Playing garbled acoustic messages backwards could take wireless
broadband communication beneath the waves, boosting the speed of data
transfers to submarines, undersea robots and data collection devices by
up to three times.
Wireless communication in the ocean is difficult because water molecules absorb radio waves very efficiently, an effect exploited by microwave ovens.
Acoustic signals travel better, but also degrade quickly due to echoes, ambient noise, swirling currents and, again, water absorbing the signals.
But a technique called acoustic time reversal can change that. The trick cleans up underwater sound signals, extending their range and capacity.
William Kuperman and colleagues at the Scripps Institution of Oceanography in La Jolla, California, US, and researchers from the NATO Undersea Research Centre in La Spezia, Italy, have been testing the technique in the Mediterranean.
Time reversal exploits the way undersea acoustic signals typically arrive clouded by echoes that travel at different speeds. For example, a "ping" may arrive as three separate sounds
Dubai plans 'moving' skyscraper
The world's first moving building, a 80-storey
tower with revolving floors giving an shifting shape, will be built in
Dubai, its architect says.
The Dynamic Tower design is made up of 80 pre-fabricated apartments which will spin independently of one another.
"It's the first building that rotates, moves, and changes shape," said architect David Fisher, who is Italian, at a news conference in New York.
"This building never looks the same, not once in a lifetime," he added.
The 420-metre (1,378-foot) building's apartments would spin a full 360 degrees, at voice command, around a central column by means of 79 giant power-generating wind turbines located between each floor.
The slender building would be energy self-sufficient as the turbines would produce enough electricity to power the entire building and even feed extra power back into the grid, said the Italian architect at the unveiling of the project in New York.
The apartments, which will take between one and three hours to make a complete rotation, will cost from $3.7m to $36m.
There are also plans to build a similar, 70-storey skyscraper in Moscow.
"I call these buildings designed by time, shaped by life," said the Florence-based architect. "These buildings will open our vision all around, to a new life."
The skyscraper will cost an estimated $700m to build and should be up and running in Dubai in 2010.

Download: FurMark v1.4.0
FurMark is a small OpenGL benchmark focused on fur rendering. The rendering algorithm is highly multipass (100 passes) and each pass (or layer) uses a GLSL (OpenGL Shading Language) vertex / pixel shader to make the hairs finer and finer. To increase the fur realism, two dynamic lights are used for self shadowing. The benchmark offers several options allowing the user to tweak the rendering: fullscreen / windowed mode, MSAA selection, window size, duration. The benchmark also includes a GPU Burner mode (stability test).
This benchmark requires an OpenGL 2.0 compliant graphics card: NVIDIA GeForce 5/6/7/8 (and higher), AMD/ATI Radeon 9600 (and higher) or a S3 Graphics Chrome 400 series with the latest graphics drivers.
The startup interface allows you to tweak the benchmark features such as:
- Benchmark mode or stability test mode (for overclockers)
- Fullscreen or windowed for each type of run mode
- Window size selection (standard or custom)
- MSAA samples selection
- Benchmarking parameters: time based or frames based
- Contest Mode

The Radeon 4870 review on Guru3D
Let me tell you a bit what is going on. AMD initially prevented 4850 & 4870 boards from being send out by it's board-partners to the press as AMD wanted to have full control over the launch. Last week at a press-briefing, AMD indeed handed out 4850 samples to the press, yet did not have 4870 samples available. These boards will definitely be available in very low volume at launch.
We where informed that these would be send out by AMD soon. Now originally today the 4850 should have been released and the 4870 at the 3rd of next month. Yet last week AMD's partners already had the 4850 board in store and on sale. Therefore AMD decided to lift the embargo, move forward the 4850 launch (which we reviewed for you) and then also move forward the 4870 launch, yet that one to be released today.
The board partners again where not allowed to ship out 4870 samples to the press, while they have them. Therefore last Monday AMD send out a 4870 board to Guru3D, yet .. it's missing somewhere in the mystic shipping mages. AMD can't even provide as much as a tracking number.
That's enough nonsense for a week AMD, I've arranged samples through board-partners which should arrive soon after which we'll have our review ready, yet I refuse this article to be another quickie / fast written review so with the 4870 we'll go in depth and wide.
More soon. Until then, check out our Radeon Series 4000 (4850) review.

NVIDIA GeForce GTX 260
NVIDIA GTX 280's little brother inspected
Roughly a week ago NVIDIA launched their GeForce GTX 200 series of products. Guru3D already published three separate articles on the GeForce GTX 280, but we figured it's about time to have a look at the little brother of the 280, the GeForce GTX 260. A product that is priced much more aggressively than it's bigger brother at 399 USD.
Obviously we'll have a chat about the differences between the GTX 260 and 280, strip her nekked and show you some photo's, but then it's time for the real deal. Gaming testing performance with the latest gaming titles, some overclocking .. and our verdict.

test: XFX GeForce 9800 GTX Black Edition review
XFX GeForce 9800 GTX Black Edition
What people seem to forget though is that there are even faster than GTX+ products on the market, now priced very competitive as well. The card we review is the XFX GeForce 9800GTX Black Edition. The fun thing is, it has even faster than GTX+ clocks and will be priced at an amazing 239-249 USD. What we'll do today is have a look at that Radeon HD 4850 performance and compare it with the default GeForce 9800 GTX and then the XFX GeForce 9800 GTX Black Edition.
Baby - Mommy of all modern computers turns 60 years !
The world's first stored-program electronic digital computer successfully executed its first program on 21st June 1948. That program was written by Tom Kilburn who, along with the late F.C. (Freddie) Williams designed and built the machine. It was called the "Small Scale Experimental Machine", but was soon nicknamed the "Baby". It is also sometimes known as the Mark 1 prototype. In modern terms the prototype Baby had a RAM (random access memory) of just 32 locations or
Sony Lost Over $3 Billion To PS3 Cost
Pricing the PlayStation 3 below its production cost caused Sony to lose $2.16 billion in 2007 and $1.16 billion in 2008, the company revealed today.
Sony's fiscal 2008 annual report delineated potential risk factors to its investors, outlining that "the large-scale investment required during the development and introductory period of a new gaming platform may not be fully recovered." The loss figures were provided as an example of the "significant negative impact" introducing a new platform can cause at first.
"In the past, large-scale investment relating to capital expenditures and research and development for the manufacture of key components, including semiconductors supplied for [PlayStation 3] was also recorded within the Electronics segment," the company said.
In order to stay competitive, said Sony, it had to invest large amounts of money in research and development to introduce the PlayStation 3 into the market, and these sorts of expenditures don't always get recouped, especially if a platform "fail[s] to achieve such favorable market penetration... resulting in a significant negative impact on Sony's profitability."
Even if it can recoup its investment, Sony said, it's still possible to have lost large amounts of money on the platform's introductory period, and even a successful PS3 might take a while to replace what it cost to produce. These possible outcomes are currently a risk for the company, S

Turbo Module Arctic Cooling
Arctic Cooling launched its RC Turbo Module (a memory cooler) and we'll finally be seeing it in stores next month.
The dual-fan cooler, pictured below, attaches to Arctic RC-cooled memory and promises to lower temperatures.
Artic claims a 74 per cent drop in temperature, when compared to RAM without a cooler, is achieved via two 1500rpm 60mm fans that are said to be "extremely quiet", ideal for the discerning overclocker.
Arctic Cooling states that the RC Turbo Module is suitable for one to four RAM modules, and comes complete with a six year limited warranty. If it's the RAM-cooler you've been waiting for, it'll be available in July at a MSRP of
