Quadrocopters Throwing and Catching an Inverted Pendulum 103

derGoldstein writes "We've seen some very impressive aerobatics performed by quadrocopters before, but this is getting ridiculous. Robohub points to the latest advancement from the Flying Machine Arena, which developed algorithms that allow quadrocopters to juggle an inverted pendulum. One of the researchers working on it said, 'We started off with some back-of-the-envelope calculations, wondering whether it would even be physically possible to throw and catch a pendulum. This told us that achieving this maneuver would really push the dynamic capabilities of the system. As it turned out, it is probably the most challenging task we've had our quadrocopters do. With significantly less than one second to measure the pendulum flight and get the catching vehicle in place, it's the combination of mathematical models with real-time trajectory generation, optimal control, and learning from previous iterations that allowed us to implement this.'"

Homeland Security Stole Michael Arrington's Boat 812

An anonymous reader writes "Michael Arrington, founder of TechCrunch, lives near Seattle and bought a boat there. He ordered it from a company based near him, but across the border in Canada. Yesterday, the company tried to deliver it to him, and it had to clear customs. An agent for the Department of Homeland Security asked him to sign a form. The form contained information about the boat, including its cost. The price was correct, but it was in U.S. dollars rather than Canadian dollars. Since the form contained legal warnings about making sure everything on it is true and accurate, Arrington suggested to the agent that they correct the error. She responded by seizing the boat. 'As in, demanded that we get off the boat, demanded the keys and took physical control of it. What struck me the most about the situation is how excited she got about seizing the boat. Like she was just itching for something like this to happen. This was a very happy day for her. ... A person with a gun and a government badge asked me to swear in writing that a lie was true today. And when I didn't do what she wanted she simply took my boat and asked me to leave.'"

al-Qaeda's 22 Tips and Tricks To Dodge Drones 303

Dr Max writes "Ever wonder how al-Qaeda operates under the watchful eye of the U.S. Army? Well, the Associated Press found a list of 22 of their tips and tricks on avoiding drone strikes. Most of it consists of the obvious: stay in the shadows or under thick trees, don't use wireless communications. However, there are also some less obvious solutions, like the $2,595 Russian 'sky grabber, which can track the drones. Their document (PDF) also suggests covering your roof and car with broken glass. They also claim good snipers can take out the reconnaissance drones, which fly at a lower level. Now the question is: will all of this still be relevant during the robo-apocalypse?"

First Dedicated Asteroid-Tracking Satellite Will Be Canadian 49

cylonlover writes "In the wake of the meteor blast over Russia and the close-quarter flyby of asteroid 2012 DA14 last week, many people's thoughts have turned to potential dangers from above. It is timely then that the Canadian Space Agency will next week launch NEOSSat (Near-Earth Object Surveillance Satellite), the world's first space telescope for detecting and tracking asteroids, satellites and space debris." The meteor incident in Russia has spurred interested in asteroid defense across the globe; donations are pouring in for asteroid-related projects, government officials are making a show of seeming interested, and researchers are stepping up their efforts. Unfortunately, as a related article at Wired notes, we're still a long, long way from having anything more than early warning systems. Quoting: "A new endeavor coming online in 2015 named the Asteroid Terrestrial-impact Last Alert System Project (ATLAS) will provide an early warning system that could provide one week’s notice for city-destroying 45-meter asteroids and three week’s notice for potentially devastating 140-meter objects. ... A more targeted effort comes from the B612 Foundation, which plans to launch the Sentinel telescope in late 2016. This spacecraft would sit inside the orbit of Venus and constantly be on the lookout for killer asteroids, whichever direction they come from. Sentinel will spot nearly all asteroids 150 meters or larger and identify a significant portion of those down to 30 meters in diameter."

Unnecessary Medical Procedures and the Dangers of Robot Surgery 130

Hugh Pickens writes "The LA Times reports that in a new report aimed at improving healthcare and controlling runaway costs, a coalition of leading medical societies has identified nearly 100 medical procedures, tests and therapies that are overused and often unnecessary. The medical interventions — including early cesarean deliveries, CT scans for head injuries in children and annual Pap tests for middle-aged women — may be necessary in some cases, but are often not beneficial and may even cause harm. 'We are very concerned about the rapidly escalating cost of healthcare,' says Dr. Bruce Sigsbee. 'This is not healthy for the country, and something has to be done.' Each of the specialty medical societies has provided a list of five procedures that physicians and patients should question about the overuse of medical tests and procedures that provide little benefit and in some cases harm. A 2012 report from the independent Institute of Medicine estimated total waste in the system at 30%, or $750 billion a year. 'Millions of Americans are increasingly realizing that when it comes to healthcare, more is not necessarily better,' says Dr. Christine K. Cassel." According to pigrabbitbear, it's the robots we should be wary of. He writes "'We are committed to helping victims of robot surgery receive the medical care and compensation they deserve. As both a lawyer and a licensed medical doctor, Dr. Francois Blaudeau has made it his mission to fight for the victims of traumatic complications as a result of botched robot surgery.' That's the opening salvo from the medical malpractice lawyers who run the slick fear factory of a website, BadRobotSurgery.com. According to the doctor-lawyers behind it—doctor-lawyers like Francois Blaudeau, MD, JD, FACHE, FCLM—'thousands of people have suffered severe and critical complications at the hands of surgical robots. In fact, 'robotic surgery has been linked to many serious injuries and severe complications, including death.'

How Sequestration Will Affect Federal Research Agencies 277

carmendrahl writes "Unless Congress and the White House act before March 1, the automatic across-the-board spending cuts known as the sequester will kick in. And federal agencies are bracing for the fiscal impact. Federal agencies and the White House are releasing details about how these cuts will affect their operations. If the cuts take effect, expect fewer inspections to the food supply, cuts to programs that support cleanups at former nuclear plants, and plenty of researcher layoffs, among other things."

NASA's Basement Nuclear Reactor 368

cylonlover writes "If Joseph Zawodny, a senior scientist at NASA's Langley Research Center, is correct, the future of energy may lie in a nuclear reactor small enough and safe enough to be installed where the home water heater once sat. Using weak nuclear forces that turn nickel and hydrogen into a new source of atomic energy, the process offers a light, portable means of producing tremendous amounts of energy for the amount of fuel used. It could conceivably power homes, revolutionize transportation and even clean the environment."

CAPTCHA Using Ad-Based Verification 174

mk1004 writes "Yahoo news has an article explaining how the text-based CAPTCHA is giving way to ad-based challenge/response. It's claimed that users are faster at responding to familiar logos, shortening the amount of time they spend proving that they are human. From the article: 'Rather than taking just a mere glance to figure out, recent studies show that a typical CAPTCHA takes, on average, 14 seconds to solve, with some taking much, much longer. Multiply that by the millions and millions of verifications per day, and Web users as a whole are wasting years and years of their lives just trying to prove they're not actually computers. This has led many companies to abandon the age-old system in favor of something not only more secure, but also easier to use for your average Webgoer: Ad-based verification, which can actually cut the time it takes to complete the task in half.'"

Mosquitoes Beginning To Ignore DEET Repellent 232

Copper Nikus writes "An article at the BBC makes a shocking claim about mosquitoes. It appears some individual insects in the wild have developed the ability to ignore the very popular DEET repellent after a first exposure. From the article: 'To investigate why this might be happening, the researchers attached electrodes to the insects' antenna. Dr Logan explained: "We were able to record the response of the receptors on the antenna to Deet, and what we found was the mosquitoes were no longer as sensitive to the chemical, so they weren't picking it up as well. "There is something about being exposed to the chemical that first time that changes their olfactory system - changes their sense of smell - and their ability to smell Deet, which makes it less effective."'"

RIAA: Google Failing To Demote Pirate Websites 165

Nerval's Lobster writes "The Recording Industry Association of America (RIAA) claims that Google has failed in its attempt to lower the search-results rankings of so-called 'pirate' Websites. "We have found no evidence that Google's policy has had a demonstrable impact on demoting sites with large amounts of piracy," read the report's summary (PDF). 'These sites consistently appear at the top of Google's search results for popular songs or artists.' Last August, Google indicated that it would start lowering the search-result rankings of Websites with high numbers of 'valid' copyright removal notices. 'This ranking change should help users find legitimate, quality sources of content more easily—whether it's a song previewed on NPR's music website, a TV show on Hulu or new music streamed on Spotify,' Amit Singhal, Google's senior vice president of Engineering, wrote in a corporate blog posting at the time. Google, which receives millions of copyright removal notices every month, also offers a counter-notice tool for those who believe their Websites have been unfairly targeted for copyright violations."

New Process Takes Energy From Coal Without Burning It 365

rtoz writes "Ohio State students have come up with a scaled-down version of a power plant combustion system with a unique experimental design--one that chemically converts coal to heat while capturing 99 percent of the carbon dioxide produced in the reaction. Typical coal-fired power plants burn coal to heat water to make steam, which turns the turbines that produce electricity. In chemical looping, the coal isn't burned with fire, but instead chemically combusted in a sealed chamber so that it doesn't pollute the air. This new technology, called coal-direct chemical looping, was pioneered by Liang-Shih Fan, professor of chemical and biomolecular engineering and director of Ohio State's Clean Coal Research Laboratory."

DRM Lawsuit Filed By Independent Bookstores Against Amazon, "Big Six" Publishers 155

concealment writes "Three independent bookstores are taking Amazon and the so-called Big Six publishers (Random House, Penguin, Hachette, HarperCollins, Simon & Schuster and Macmillan) to court in an attempt to level the playing field for book retailers. If successful, the lawsuit could completely change how ebooks are sold. The class-action complaint, filed in New York on Feb 15., claims that by entering into confidential agreements with the Big Six publishers, who control approximately 60 percent of print book revenue in the U.S., Amazon has created a monopoly in the marketplace that is designed to control prices and destroy independent booksellers."

Millionaire Plans Mission To Mars In 2018 97

littlesparkvt writes in with news about the possibility of a privately funded Mars mission. "Millionaire Dennis Tito became the first paying customer to make a trip to the International Space Station and now he wants to launch a privately funded mission to Mars in 2018. Dennis paid a reported 20 Million to ride aboard a Russian rocket to the International Space Station and has since stayed out of the spotlight, until now. There’s no word whether the trip will include humans, there will be more information on that fact next week. Considering there is little time to train a crew for the mission the flight in 2018 will most likely be an unmanned probe. There’s also a possibility that the first mission to Mars from this private investor will harbor supplies for future astronauts. Plants and food are a possibility as they would take much less space than a full human crew."
