Ponca City, We Love You writes "New technologies could soon allow scientists to generate acomplete wiring diagram of a piece of brain. With an estimated 100 billion neurons and 100 trillion synapses in the human brain, creating an all-encompassing map of even a small chunk is a daunting task. Only one organism's complete wiring diagram now exists: that of the microscopic worm C. elegans, which contains a mere 302 neurons. The C. elegans mapping effort took more than a decade to complete. Research teams at MIT and at Heidelberg in Germany are experimenting with different approaches to speed up the process of mapping neural connections. The Germans start with a small block of brain tissue and bounce electrons off the top of the block to generate a cross-sectional picture of the nerve fibers. They then take a very thin slice, 30 nanometers, off the top of the block. 'Repeat this [process] thousands of times, and you can make your way through maybe the whole fly brain,' says the lead researcher. They are training an artificial neural network to emulate the human process of tracing neural connections to speed the process about 100- to 1000-fold. They estimate that they need a further factor of a million to analyze useful chunks of the human brain in reasonable times."Read more of this storyat Slashdot.
Reservoir Hill writes "Sailors have been telling stories for centuries about monstrous ocean waves that tower over a hundred feet in the air and toss ships around like corks. While these were once dismissed as nautical myth, but a few years back synthetic aperture radar from ESA's ERS satellites helped establish the existence of these 'rogue' waves and study their origins. Such waves were far more common than anyone had expected. Now a researcher in Madrid has developed software that can detect rogue waves from radar images, with the possibility of providing advance warning to ships at sea. The software uses a mathematical model to evaluate and process the spatial and temporal dimensions of waves inferred from the interaction between the radar's electromagnetic energy and the sea surface. The result is displayed in a color-coded image."Read more of this storyat Slashdot.
The_Rook writes "The Discovery Institute, more a lawyer mill than a scientific institution, copied Harvard University's BioVisions video 'The Inner Life of the Cell,' stripped out Harvard's copyright notice, credits, and narration, inserted their own creationist-friendly narration, and renamed the video 'The Cell As an Automated City.' The new title subtly suggests that a cell is designed rather than evolved."Read more of this storyat Slashdot.
Tech.Luver writes "Astronauts spent seven hours in space to finish preparing the International Space Station for its next addition — Europe's first permanent space laboratory, the Columbus laboratory — which is sitting in the cargo bay of space shuttle Atlantis at Cape Canaveral, Florida launch pad — set to lift off on December 6."Read more of this storyat Slashdot.
Xight writes "The Santa Fe Reporter has up an article about a portable nuclear reactor, about the size of a hot tub. Despite it's 'small' size the company that is planning to develop the product (Hyperion Power Generation), claims it could power up to 25,000 homes. 'Though it would produce 27 megawatts worth of thermal energy, Hyperion doesn't like to think of its product as a reactor. It's self-contained, involves no moving parts and, therefore, doesn't require a human operator. "In fact, we prefer to call it a 'drive' or a 'battery' or a 'module' in that it's so safe," Hyperion spokeswoman Deborah Blackwell says. "Like you don't open a double-A battery, you just plug [the reactor] in and it does its chemical thing inside of it. You don't ever open it or mess with it."' If all goes according to plan, Hyperion could have a factory in New Mexico by late 2012, and begin producing 4,000 of these reactors."Read more of this storyat Slashdot.
Nanotech Coward writes "The unknown human health and environmental impacts of nanotechnology are a bigger worry for scientists than for the public, according to a new report in the journal Nature Nanotechnology. The new report was based on a national telephone survey of American households and a sampling of 363 leading U.S. nanotechnology scientists and engineers. It reveals that those with the most insight into a technology with enormous potential — and that is already emerging in hundreds of products — are unsure what health and environmental problems might be posed by the technology."Read more of this storyat Slashdot.
Fantastic Lad writes "Chinese leaders hailed images sent back from the country's first lunar satellite on Monday, saying they showed their nation had thrust itself into the front ranks of global technological powers. China plans to launch its third manned rocket, Shenzhou VII, into space in October 2008 and may send an astronaut on a space walk, a Shanghai paper said. But a space official downplayed plans to put a man on the moon."There are no plans at the moment to send anyone on to the moon. I've heard of foreign reports which say China will put a man on the moon by 2020, but I don't know of such a plan," said Sun Laiyan, head of the China National Space Administration. "Please don't give us any more pressure. But I'm confident one day we'll put an astronaut on the moon," he told a news conference."Read more of this storyat Slashdot.
Researchers at Sandia National Laboratories in California are developing a new neutron scatter camera that they claim will be able to detect radiation through much more shielding and at much greater distances than traditional tech. "The neutron scatter camera consists of elements containing proton-rich liquid scintillators in two planes. As neutrons travel through the scintillator, they bounce off protons like billiard balls. This is where "scatter" comes into play -- with interactions in each plane of detector elements, the instrument can determine the direction of the radioactive source from which the neutron came. [...] Computers record data from the neutron scatter camera, and using kinematics, determine the energy of the incoming neutron and its direction. Pulse shape discrimination is employed to distinguish between neutrons and gamma rays."Read more of this storyat Slashdot.
Smivs writes to mention that a new 3D scanner, unveiled at the Radiological Society of North America, has been in use for the last month at the Metro Health medical center in Cleveland, Ohio. This new scanner allows for much more detailed scans of the entire body in just under one minute also cutting the exposure to x-rays by as much as 80%. The cost of the new tech has not yet been released.Read more of this storyat Slashdot.
coondoggie writes to tell us that a new freighter set to launch in December will be receiving a hefty dose of power from a kite the size of a football field. The 460-foot ship, owned by the Beluga shipping company, hopes to see as much as a 50% drop in fuel consumption during optimal conditions. "The SkySails system consists of a towing kite with rope, a launch and recovery system and a control systemfor the whole operation. The control system acts like the autopitot systems on an aircraft, the company says. Autopilot software sends and receives data about the sail etc to make sure the sail is set at its optimal position. The company also says it provides an optional weather routing system so that ships can sail into optimal wind conditions.The kites typically fly at about 1,000 feet above sea level, thereby tapping winds that can be almost 50% stronger than at the surface.

AnonymousHack writes "Swiss and MIT researchers have developed a wearable kit that will capture your every move for mapping onto a virtual character. It's almost as accurate as the camera-based motion capture used in studios to develop games. The team have recorded people's movements in completely new locations — like driving a car — previously out of reach. There is even a video of it in action."Read more of this storyat Slashdot.
HeavensBlade23 sends in an article from the German site Spiegel Online about mounting evidence that nuclear radiation may not be as deadly as has been widely believed. The article cites studies by German, US, and Japanese researchers concluding, for example, that fewer than 800 deaths are attributable to the after-effects of radiation in over 86,500 survivors of the Hiroshima bombing. Other surprisingly low death rates are reported in studies of Chernobyl and of a secret Siberian town called Mayak, devoted to producing plutonium, that was abandoned after a nuclear accident in 1957.Read more of this storyat Slashdot.
ZDOne writes "ZDNet UK has put together a list of some of the biggest obstacles preventing information technology from achieving its true potential, in terms of development and progress. Microsoft's stranglehold on the desktop makes the list, as does the chip-makers' obsession with speed. 'There is more to computing than processor speed -- a point which can be easily proven by comparing a two-year-old PC running Linux with a new PC buckling under the weight of Vista. Shrinking the manufacturing process to enable greater speed has proven essential, but it's running out of magic ... What about smarter ways of tagging data? The semantic web initiative runs along these sorts of lines, so where is the hardware-based equivalent?'"Read more of this storyat Slashdot.
Invisible Pink Unicorn writes "One of the most comprehensive analyses of genetic variation ever undertaken supports the theory that the ancestors of modern native peoples throughout the Americas came from a single source in East Asia across a northwest land bridge some 12,000 years ago. One particular discovery is of a 'unique genetic variant widespread in natives across both continents — suggesting that the first humans in the Americas came in a single migration or multiple waves from a single source, not in waves of migrations from different sources.' The full article is available online from PLoS."Read more of this storyat Slashdot.
