US To Send Radiation-Hardened Robots To Japan 183

CWmike writes "The United States is sending specialized robots to Japan to help officials there get control of the Fukushima nuclear power plants damaged in this month's devastating earthquake and tsunami. Dr. Peter Lyons, an acting assistant secretary for nuclear energy with the DoE, said the robots, which could be sent into areas that would be dangerous for humans to enter because of high radiation levels, could begin to give officials readings on the environment inside the nuclear power plants. Lyons told the US Senate on Tuesday, 'We are moving expeditiously to ship not only the robots but also operators who perhaps will be used to train Japanese operators. We don't know yet how close the operators will need to be to the site.' Asked about getting information about the state of the damaged reactors, Lyons said the robots could provide some information. 'Certainly not all we need, but some,' he said."

MIT Drone Finds Its Way Using Kinect Vision 77

garymortimer writes "This MIT multicopter is able to fly in GPS denied environments by creating a 3D map of its surroundings on the fly (no pun intended) based on point clouds generated by a Kinect. Also pretty handy for avoiding trees and other obstacles outside at low level. This processing is onboard, unlike other systems that depend on motion capture rigs."

Mars Rover Down? Spirit Stays Silent 91

astroengine writes "One year after NASA's Mars Exploration Rover Spirit stopped communicating with Earth, mission managers have announced that they will give the stranded rover one more month to send a signal before they scale back the search. But things aren't looking good. In the words of JPL-based Mars rover driver Scott Maxwell, 'Spirit was so close to us, just a year ago. Snap your fingers, and she's a hundred million miles distant and we can't even prove she's alive.'"

Does 3D Make Your Head Happy Or Ache? 281

MojoKid writes "Nintendo has quasi-acknowledged that its 3DS can cause headaches and should not be used by children under 7. The glasses-free 3D handheld gaming device launched this week. Meanwhile, new research commissioned by the Blu-ray Disc Association is trying to improve the health image of 3D. Its research shows that the brain is more attentive when watching a 3D movie than when watching HD or SDTV, making the movie a more pleasurable experience. The issue, doctors say, is that 3D works by tricking the brain into making you think you are physically moving in relation to your surroundings. But you aren't. So your inner ear is not experiencing the movement that corresponds to what the eyes are seeing. This doesn't normally happen in real life. No one would deny that 3D is more immersive; that's why people like it, particularly for gaming. But the question is ... does the brain love 3D or not? Answer: not really."

Browser Power Consumption Compared 274

theweatherelectric writes "Over on the IE Blog they've posted a power consumption comparison of the five major browsers. They write: 'Power consumption is an important consideration in building a modern browser and one objective of Internet Explorer 9 is to responsibly lead the industry in power requirements. The more efficiently a browser uses power the longer the battery will last in a mobile device, the lower the electricity costs, and the smaller the environment impact. While power might seem like a minor concern, with nearly two billion people now using the Internet the worldwide implications of browser power consumption are significant.'"

Things Get Worse at Fukushima 1122

An anonymous reader writes "Radiation levels are skyrocketing around Japan's Fukushima nuclear plant as reports indicate that a radioactive core has overheated and melted through its containment vessel and onto a concrete floor. Radiation levels inside reactor two were recently gauged at 1,000 millisieverts per hour — a level so high that workers could only remain in the area for 15 minutes under current exposure guidelines."

Artificial Leaf Could Provide Cheap Energy 326

sciencehabit was one of several readers to tip news of a sunlight-harvesting artificial leaf, writing: "Nearly all the energy we use on this planet starts out as sunlight that plants use to knit chemical bonds. Now, for the first time, researchers at the Massachusetts Institute of Technology have created a potentially cheap, practical artificial leaf that does much the same thing—providing a vast source of energy that's easy to tap. The new device is a silicon wafer about the shape and size of a playing card coated on either side with two different catalysts. The silicon absorbs sunlight and passes that energy to the catalysts to split water into molecules of hydrogen and oxygen. Hydrogen is a fuel that can be either burned or used in a fuel cell to create electricity, reforming water in either case. This means that in theory, anyone with access to water can use it to create a cheap, clean, and available source of fuel."

Intel Replaces Consumer SSD Line, Nixes SLC-SSD 165

Lucas123 writes "Intel today launched a line of consumer solid state drives that replaces the industry's best selling X25-M line. The new 320 series SSD doubles the top capacity over the X25-M drives to 600GB, doubles sequential write speeds, and drops the price as much as 30% or $100 on some models. Intel also revealed its consumer SSDs have been outselling its enterprise-class SSDs in data centers, so it plans to drop its series of single-level cell NAND flash SSDs and create a new series of SSDs based on multi-level cell NAND for servers and storage arrays. Unlike its last SSD launch, which saw Intel use Marvell's controller, the company said it stuck with its own processing technology with this series."

Radioactive Water Found In Two Reactor Buildings 442

RedEaredSlider writes "Japan's Nuclear and Industrial Safety Agency said it detected several kinds of radioactive material in the water on the floor of reactor buildings at the Fukushima Daiichi nuclear power plant. The isotopes found in the water were cobalt-76, technetium-99, silver-108, iodine-131, iodine-134, four isotopes of cesium, barium-140 and lanthanum-140. All have half-lives measured in hours or days, with the exception of cesium-137."

Americans Favor Moratorium On New Nuclear Reactors 964

An anonymous reader writes "While a drop in public support for nuclear power would be expected after an incident like the Fukushima reactor crisis, the nuclear disaster in Japan has triggered a much stronger response among Americans. When Japan — the nation that President Obama held up as an example of safe nuclear power being used on a large-scale basis — is unable to effectively control its considerable downside, Americans are understandably leery about the same technology being used even more extensively in this nation. And safety concerns about the existing nuclear plants also deserve serious attention."

It is amazing to watch and all the more amazing when you realize that it flaps its wings and all of the control is via a torsion drive which twists the wings during each flap. The whole thing depends on the constant intervention of the software to keep it under control."

Ask Slashdot: How Do You Choose a Windows Laptop? 898

jfruhlinger writes "I'm a Mac guy. When our 2004-era Windows XP laptop, which was used primarily by my wife, died last summer, I got myself a new MacBook Pro and she inherited my still serviceable 2008 MacBook. But after about six months, she hasn't gotten used to it, and wants a Windows machine. I don't have an ideological problem with this — it'd be her computer, and we've got a bit of money stashed away to pay for it. But trying to pick one out is my job, and I find the the whole process bewildering. Apple's product differentiation is great at defeating the paradox of choice — you have a few base models, the difference between which is quite obvious, and you can customize each. The Windows world seems totally different. Even once I've settled on a vendor for a Windows laptop (something I haven't done yet), each seems to have a bewildering array of product lines with similar specs. Often models that you find in electronics or office supply stores that seem promising in terms of form factor are exclusive to those stores and can't be found online. Obviously people do navigate this process, but I'm just feeling out of my depth. How would Slashdotters go about picking a solid, basic laptop for Web surfing and document editing that won't be obsolete in two years?"

Turning Your E-Reader Into a Cheap Tablet 193

grahamsaa writes "NPR's Weekend Edition aired a story today on how rooting the Nook Color can turn it into a full fledged and relatively inexpensive Android tablet. The story claims that the process takes about half an hour, and only requires the purchase of a Nook and a microSD card, and points listeners to a YouTube tutorial on how to root the device. Could this signal a change in how mainstream users see devices like this? Could rooting Android devices like the Nook ever become mainstream?" We ran a story about this in December, and I haven't seen a flood of hacked readers anywhere so I doubt that tablet makers have anything to worry about.

Kinect's AI Breakthrough Explained 97

mikejuk writes "Microsoft Research has just published a scientific paper (PDF) and a video showing how the Kinect body tracking algorithm works — it's almost as impressive as some of the uses the Kinect has been put to. This article summarizes how Kinect does it. Quoting: '... What the team did next was to train a type of classifier called a decision forest, i.e. a collection of decision trees. Each tree was trained on a set of features on depth images that were pre-labeled with the target body parts. That is, the decision trees were modified until they gave the correct classification for a particular body part across the test set of images. Training just three trees using 1 million test images took about a day using a 1000-core cluster.'"

Inside a Verizon Wireless Superswitch 107

An anonymous reader writes "Geek.com has posted a walkthrough of a Verizon Wireless Superswitch, a 45,000 square foot, $50 million facility. From the article: 'The Superswitch we visited, located in Orlando, Fl., is one of about 25 across the US. These control centers are designed to handle mobile calls, SMS, MMS, and mobile broadband for their respective regions. This particular Superswitch faces a somewhat unique problem given its unfortunate proximity to extreme weather conditions, and as such is re-enforced to survive a Category 5 hurricane and still provide service to its area. While definite numbers were unavailable, this center handles millions of calls and texts, as well as tens of thousands of gigabytes of mobile data on an average day, and is designed to scale up rapidly for large events or emergencies.'"

The First Plastic Computer Processor 73

jcombel writes "There's been a lot of talk lately about developing replacements for silicon; how about a nearly-transparent film of plastic, woven into clothing or affixed directly to equipment? From the article, 'Researchers in Europe used 4,000 plastic, or organic, transistors to create the plastic microprocessor, which measures roughly two centimeters square and is built on top of flexible plastic foil. ... The processor can so far run only one simple program of 16 instructions. The commands are hardcoded into a second foil etched with plastic circuits that can be connected to the processor to "load" the program. This allows the processor to calculate a running average of an incoming signal, something that a chip involved in processing the signal from a sensor might do.'"
