quax writes "In the wake of the Fukushima disaster the nuclear industry again faces massive opposition. Germany even decided to abandon nuclear energy altogether and the future of the industry is under a cloud of uncertainty in Japan. But one thing seems to be here to stay for a very, very long time: radioactive waste that has half-lives measured in thousands of years. But there is a technology under development in Belgium that could change all this: A sub-critical reactor design, driven by a particle accelerator can transmute the nuclear waste into something that goes away in about two hundred years. Could this lead to a revival of the nuclear industry and the reprocessing of spent reactor fuel?"

New submitter stacey7165 writes "VMware shared the application architecture story of how they worked with the Ocean Observatory Initiative to build a 'Hubble Telescope' of the ocean. It's comprised of a massive network of global, regional, and coastal sensors that send information to a common framework called the Common Operating Infrastructure (COI). The COI resides in a hybrid cloud powered by VMware and Amazon. To cope with a total of 49 classes and over 700 instruments deployed off of 6 coastlines, and a variety of consumption use cases, the Ocean Observatory Initiative built out the system using a variety of sub-systems loosely coupled through a messaging system powered by RabbitMQ called an 'Exchange.' Organized into a system where message clients pubsub from 'Exchange Points' and 'Exchange Spaces', the system is easier to maintain, extend, and scale. According to the OOI's documentation on release 1, the Integrated Observatory Network uses AMQP 0.9.1 and RabbitMQ-Server v. 2.3.1 on CentOS 5.5."

MrSeb writes with news on work toward flexible batteries good enough for Real World use (you have to power those flexible electrionics somehow). From the article: "LG Chem ... has devised a cable-type lithium-ion battery that's just a few millimeters in diameter, and is flexible enough to be tied in knots, worn as a bracelet, or woven into textiles. The underlying chemistry of the cable-type battery is the same as the lithium-ion battery in your smartphone or laptop — there's an anode, a lithium cobalt oxide (LCO) cathode, an electrolyte — but instead of being laminated together in layers, they're twisted into a hollow, flexible, spring-like helix. flexible batteries have been created before — but they've all just standard, flat, laminated batteries made from sub-optimum materials, such as polymers. As such, as they have very low energy density, and they're only bendy in the same way that a thin sheet of plastic is bendy. LG Chem's cable-type batteries have the same voltage and energy density as your smartphone battery — but they're thin and highly flexible to boot. LG Chem has already powered an iPod Shuffle for 10 hours using a knotted 25cm length of cable-type battery." Original paper (Extreme Tech claims it is paywalled, but it looks like it's not). The hollow core seems to be the key: "Moreover, a nonhollow anode proved to have serious problems with penetration of the electrolyte into the essential cell components such as the separator and active materials ... However, we were able to overcome these drawbacks by devising a unique architecture comprising a skeleton frame surrounding an empty space, that is, a hollow-spiral anode with a multi-helix structure This design enables easy wetting of the battery components with the electrolyte and the hollow space allows the device to compensate for any external mechanical distortion while maintaining its structural integrity. In addition, this helical architecture possibly enables the battery to be more flexible, owing to its similarity to a spring-like structure."

Diggester writes "Researchers at the University of Cape Town in South Africa have developed a pill that can wipe out malaria with a single dose. It's a development that could save millions of lives in Africa alone, not to mention the rest of the world. But there's a teensy weensy little hurdle that must first be overcome: human testing. According to National Geographic, 'Clinical tests are scheduled for the end of 2013. If this tablet is approved in coming years, this achievement will surely usher in a new age for science in Africa. It will save millions upon millions of lives on the continent, helping avoid at least 24 percent of child deaths in sub-Saharan Africa.'"

coondoggie writes "The U.S. Naval Research Laboratory (NRL) researchers said recently that a Navy very high-resolution Doppler radar can actually spot individual raindrops in a cloudburst, possibly paving the way for new weather monitoring applications that could better track or monitor weather and severe storms. According to an NRL release, the very high-resolution 'Mid-Course Radar' was used to retrieve information on the internal cloud flow and precipitation structure. The radar was previously used to track small debris shed from the NASA space shuttle missions during launch. 'Similar to the traces left behind on film by sub-atomic particles, researchers observed larger cloud particles leaving well-defined, nearly linear, radar reflectivity "streaks" which could be analyzed to infer their underlying properties,' NRL stated."

An anonymous reader sends this quote from Nature: "David Brady, an engineer at Duke University in Durham, North Carolina, and his colleagues are developing the AWARE-2 camera with funding from the United States Defence Advanced Research Projects Agency (abstract). The camera's earliest use will probably be in automated military surveillance systems, but its creators hope eventually to make the technology available to researchers, media companies and consumers. ... AWARE-2 sidesteps the size issue by using 98 microcameras, each with a 14-megapixel sensor, grouped around a shared spherical lens. Together, they take in a field of view 120 degrees wide and 50 degrees tall. With all the packaging, data-processing electronics and cooling systems, the entire camera is about 0.75 by 0.75 by 0.5 metres in volume. The current version of the camera can take images of about one gigapixel; by adding more microcameras, the researchers expect eventually to reach about 50 gigapixels. Each microcamera runs autofocus and exposure algorithms independently, so that every part of the image — near or far, bright or dark — is visible in the final result. Image processing is used to stitch together the 98 sub-images into a single large one at the rate of three frames per minute."

Harperdog writes "Scott Kemp writes about the similarities between the nuclear arms race and the use of cyberweaponry for offensive purposes. As the article points out, offensive cyberwarfare leaves a nation's own citizenry vulnerable to attack as government agencies seek to keep weaknesses in operating systems (such as Windows) secret. Quoting: 'In the world of armaments, cyber weapons may require the fewest national resources to build. That is not to say that highly developed nations are not without their advantages during early stages. Countries like Israel and the United States may have more money and more talented hackers. Their software engineers may be more skilled and exhibit more creativity and critical thinking owing to better training and education. However, each new cyberattack becomes a template for other nations — or sub-national actors — looking for ideas.'"

snowdon writes "The race for low-latency in finance and HPC has taken a major turn. A bunch of engineers from Australia have 'thrown away the air conditioning' in a traditional switch, to get a 10G fibre-to-fibre latency of less than 130ns! Way faster than more traditional offerings. This lady (video) would tell you that it's equivalent to just 26m of optical fibre. Does that mean we just lose money faster?"

Hugh Pickens writes "AP reports that a fire that swept through a nuclear-powered submarine in dry dock at Portsmouth Naval Shipyard has caused such extensive damage to its forward compartments that the 22-year-old Los Angeles-class attack submarine might have to be scrapped. 'These submarines were designed decades ago. So they're no longer state of the art,' says analyst Loren Thompson. 'If this vessel returns to service, I will be amazed.' The fire broke out while the Miami was on a 20-month stay at the shipyard for an overhaul, and it took firefighters from more than a dozen agencies twelve hours to put out the fire, described as intense, smoky, and a 'hot scary mess.' 'It takes a lot of guts to go into a burning building. But the idea of going into a submarine full of hot toxic smoke — that's real courage,' said U.S. Rep. Chellie Pingree after meeting with the shipyard commander. Firefighters isolated the flames so they would not spread to nuclear propulsion spaces at the rear of the submarine. There was nuclear fuel on board the sub, but the reactor has been shut down for two months and was unaffected. Rear Admiral Rick Breckenridge says an investigation has been launched into what caused the fire, but he expects that investigation to take a long time to complete and wouldn't say if human error has been ruled out as a cause of the fire, or if the focus is on mechanical issues."

ananyo writes "A newly-discovered microbial community living tens of meters beneath the Pacific Ocean floor uses so little oxygen that researchers believe they may be living at the absolute minimum energy requirement needed to subsist. For years, scientists thought that the ascetic conditions of the deep sub-seabed — high pressure, minimal oxygen and a low supply of nutrients and energy — made such environments uninhabitable to any form of life. The discovery extends the lower bound for life (abstract). The surface of Mars, for instance, may be inhospitable, but there may be conditions below the surface that are reminiscent of the deep subsurface on Earth. As microbiologist Bo Jørgensen comments in the Nature piece, while the discovery does not mean there is life on Mars, 'it's now really challenging to show where there is no life.'"

Okian Warrior writes "Tattoo artist Jersey from Dynasty Tattoo (in New Jersey) implanted sub-dermal magnets in his arm to wear his iPod touch like a watch. From the article: '“Those magnets are actually called micro-dermal anchors, and in body piercing they are very common. The tops are actually just 5 millimetre magnetic tops,” he said. “I took the ends of magnets and actually adhered them to the back of the iPod, and that’s how they click into my skin.” He added: “I can go for a run and it won’t come off. I’ve already taken it to the gym and jogged with it on.”'"

Lucas123 writes "Researchers at UCLA have created an online crowdsourcing game designed to let players help doctors in key areas of the world speed the lengthy process of distinguishing malaria-infected red blood cells from healthy ones. So far, those playing the game have collectively been able to accurately diagnose malaria-infected blood cells within 1.25% of the accuracy of a pathologist performing the same task (PDF). The researchers hope that users of the game can help eliminate the high cost and sometimes poor accuracy of diagnosis in areas like sub-Saharan Africa, where malaria accounts for some 20% of all childhood deaths."

An anonymous reader writes "Researchers from the University of Lugano, Switzerland, and other universities from the U.S. and Europe organize a competition to automatically identify sexual predators in chat logs. The task is described as: 'The goal of this sub-task is to identify classes of authors, namely online predators. You will be given chat logs involving two (or more) people and have to determine who is the one trying to convince the other participants(s) to provide some sexual favor. You will also need to identify the particular conversation where the person exploits his bad behavior.' Their data set covers hundreds of chat logs with dozens of true positives (i.e., chats where one is trying to hit on another)."

kodiaktau writes "An interesting article from the BBC News Magazine explores the reasons why most fantasy worlds use British as their primary accent. Citing specific examples from recent and upcoming shows and movies like Lord of The Rings, The Hobbit and Game of Thrones, the article concludes British accents are 'sufficiently exotic,' 'comprehensible' and have a 'splash of otherness.' It would be odd to think of a fantasy world having a New Jersey accent, or even a Mid-West accent, which tends to be the default for TV and movies in the U.S., but how do UK viewers feel about having British as a default? More specifically, what about the range of UK accents, like Scottish, Welsh, Cockney? The International Dialects of English Archive shows at least nine regional sounds, with dozens of sub-regional pronunciations in England alone. In the U.S., there have always been many regional accents that might be used in interesting ways. Filmmakers should consider looking at speech accents from other areas of the world to create more interesting dialects."

An anonymous reader writes "Ian O'Neill suggests in an opinion piece at Al Jazeera that brown dwarves and nomad planets (planets not orbiting any star) could be a much needed stepping stone on our way to foreign stars. Quoting the article: 'In February, a fascinating paper was published in the Monthly Notices of the Royal Astronomical Society detailing calculations on how many "nomad planets" the Milky Way must contain after estimating our galaxy's mass from how much gravity it exerts on surrounding space. Scientists from the Kavli Institute for Particle Astrophysics and Cosmology (KIPAC) had uncovered something surprising — there are likely many more planets in the Milky Way than stars. ... Louis Strigari and his Kavli team calculated that there must be 100,000 planets for every star in the Milky Way (PDF). That's a lot of planets! But how can this be? Every star can't have tens of thousands of planets ranging from Pluto-sized to Jupiter-sized. This planetary "excess" actually suggests the existence of planets that were born without a star — nomad planets. ... we need all the help we can get if we are to venture to another star, so these ultracool brown dwarfs could become much-needed "stepping stones" for future starships to refuel on their light-years of journey time. There may be the possibility that these sub-stellar objects may even become more desirable targets for interstellar travellers. After all, there may be dozens of these invisible objects between here and Proxima just waiting to be uncovered by the sophisticated infrared telescopes of the future; they'd certainly make for more accessible scientific curiosities.'"

An anonymous reader writes "For over 70 years, transmission electron microscopy (TEM), which 'looks through' an object to see atomic features within it, has been constrained by the relatively poor lenses which are used to form the image. The new method, called electron ptychography, dispenses with the lens and instead forms the image by reconstructing the scattered electron-waves after they have passed through the sample using computers. Scientists involved in the scheme consider their findings to be a first step in a completely new epoch of electron imaging. The process has no fundamental experimental boundaries and it is thought it will transform sub-atomic scale transmission imaging."

New submitter dcraid writes with a quote from El Reg: "Microsoft's cloudy platform, Windows Azure, is experiencing a major outage: at the time of writing, its service management system had been down for about seven hours worldwide. A customer described the problem to The Register as an 'admin nightmare' and said they couldn't understand how such an important system could go down. 'This should never happen,' said our source. 'The system should be redundant and outages should be confined to some data centres only.'" The Azure service dashboard has regular updates on the situation. According to their update feed the situation should have been resolved a few hours ago but has instead gotten worse: "We continue to work through the issues that are blocking the restoration of service management for some customers in North Central US, South Central US and North Europe sub-regions. Further updates will be published to keep you apprised of the situation. We apologize for any inconvenience this causes our customers." To be fair, other cloud providers have had similar issues before.

First time accepted submitter superfast-scooter writes "I wanted to let the community know of a research project I've been fortunate to be part of — it's a rural electrification project called SharedSolar at the Modi Research Group at Columbia University. The project has 17 pilot sites in sub-Saharan Africa to-date, providing prepaid energy services to over 3000 people who did not have access to electricity — a fraction of the over 1.3 Billion worldwide. The lab has been developing custom software applications to integrate off-the-shelf hardware components, and also provide the operational and management mechanisms needed. Communications with the sites are over the mobile networks. Consumers can recharge their accounts using either cellphones, or visit a designated local vendor who can do it at the site using an Android app. Software residing locally makes each site autonomous, and the online platform allows for remote visibility, localized consumer interactions and integration with payment solutions. And we're planning on deploying soon in Haiti and Kenya."

Griller_GT writes "According to the top researchers of the Fraunhofer-Institut für Arbeitswirtschaft und Organization (IAO) in Stuttgart, the human mind is set up to work at its best under the open sky, with changing illumination caused by clouds passing overhead. The unvarying glare of office lighting is sub-optimal, therefore, and in order to wring the last ounce of efficiency from German workers whose productivity has already been pushed to unprecedented heights they have decided to rectify this with a LED cloud ceiling."

Hugh Pickens writes "The magnitude-9.0 Tohoku-Oki temblor, the fifth-most powerful quake ever recorded, triggered a tsunami that doubled in intensity over rugged ocean ridges, amplifying its destructive power at landfall, as seen in data from NASA and European radar satellites that captured at least two wave fronts that day, which merged to form a single, double-high wave far out at sea. This wave was capable of traveling long distances without losing power. Ocean ridges and undersea mountain chains pushed the waves together along certain directions from the tsunami's origin. 'It was a one-in-10-million chance that we were able to observe this double wave with satellites,' says study team member Y. Tony Song. 'Researchers have suspected for decades that such 'merging tsunamis' might have been responsible for the 1960 Chilean tsunami that killed about 200 people in Japan and Hawaii, but nobody had definitively observed a merging tsunami until now.' The study suggests scientists may be able to create maps that take into account all undersea topography, even sub-sea ridges and mountains far from shore to help scientists improve tsunami forecasts."
