RedEaredSlider writes "If you plan on terrorizing the world with cyanide poison, you may have to think up another way. Steve Patterson, at the University of Minnesota’s Center for Drug Design, and his team have made an antidote that can be given with a simple injection. It's based on a sulfanegen triethanolamine (TEA). The sulfanogen allows the body to convert the cyanide to a much less toxic chemical called thiocyanate. It works fast, in minutes rather than hours, and is less involved than current antidotes to administer. It could also be a big help in industrial accidents, in which a few people get injured or killed by cyanide every year."Link to Original Source
RedEaredSlider writes "Fusion is often derided as "the energy source of the future — and it always will be." But now at Sandia they've done the first in a series of experiments that could lead to a working reactor, and one that doesn't require developing new technologies or a tokamak. Using a cylinder of berylium, they showed that you can crush it with a magnetic field, which would in turn crush any (pre-heated) deuterium-tritium mix inside it. That would result in a fusion reaction. The next step is to try the same experiment with real fuel inside. There's still some way to go, but this experiment does show what concrete steps can be taken (assuming each experiment works) on the way to building real fusion power plants."Link to Original Source
RedEaredSlider writes "Researchers from Princeton's School of Engineering and Applied Science have written a program called SSDAlloc, which tells a computer running to pretend that it's running using RAM, even though it's actually accessing the storage (flash) memory.
Most computers are designed to look in the RAM first for the data they need. Only after that does the operating look elsewhere, such as on the hard drive or a flash drive. That kind of hierarchical searching around can really slow things down.
SSDAlloc changes that, basically making a computer pretend the flash is the RAM. That cuts power consumption by up to 90 percent, the researchers say, because flash doesn't need power to run nor does it use the power that hard drives do."Link to Original Source
RedEaredSlider writes "Researchers at MIT have developed a new kind of glass for displays — one that repels water and grit. The bonus: it can be made with exiting technology and equipment. The glass surface is made up of nanometer-scale cones (they actually can stand up to quite a lot of force) that prevent dirt and water from sticking to the surface."Link to Original Source
RedEaredSlider writes "Scientists are looking at the lowly lamprey for inspiration on building a robot that would swim around the insides of people and check for various disorders. The idea is to combine microelectronics with advances in glucose-powered artificial muscles, and use living cells as parts of the sensor. The lamprey-like bot is called a 'Cyberplasm' and would react to the environment the way an animal does."Link to Original Source
RedEaredSlider writes ""Supersonic passenger jet service ended with the Concorde's retirement in October, 2003, but that hasn't stopped people from trying to build a successor. At MIT an aeronautics professor turned to a design that dates to the 1950s to design a biplane that can travel faster than sound.
Qiqi Wang, an assistant professor of aeronautics and astronautics, used Busemann's Biplane, named for Adolf Busemann, as the basis for his idea. Sixty years ago, Busemann proposed that a plane moving at supersonic speeds that had two pairs of wings, almost joined at the tips to form a hollow space, would create an airflow that eliminated sonic booms.""Link to Original Source
RedEaredSlider writes "There are some 7,000 languages spoken in the world, and half of them could be gone by 2100. To rescue these languages, two linguists decided to use a combination of digital recording technology and the Internet.
K. David Harrison and Gregory Anderson are compiling what they call "talking dictionaries." Some of the languages they recorded have never been documented before. In 2010, they made the first recordings of Koro, for example, a language spoken by only a few hundred people in northeastern India.
Some of the work is available online. In one case, a community in Papua New Guinea that speaks a language called Matukar Panau, with only 600 speakers, asked that the language be put on the Internet even though it was only in the last two years that their village received electricity."Link to Original Source
RedEaredSlider writes "Peter Stone, associate professor of computer science at the University of Texas at Austin, has presented an idea at the AAAS meeting today for managing intersections: a computer in a car calls ahead to the nearest intersection it is headed towards, and says it will arrive at a given time. The intersection checks to see if anyone else is arriving then, and if the slot is open, it tells the car to proceed. If it isn't, it tells the car that and the car is responsible for slowing down or stopping.
He says that even with only a few connected cars, the system still works, even if the benefits are still only to those who have the connected vehicles."Link to Original Source
RedEaredSlider writes "Cloaks in time as well as space have been studied as a way to hide things — but they can also reveal. Some work on the time cloaking at Cornell has led some scientists to the idea that you can use the cloaking effect to show whether a signal has been tampered with. Stitching together two pieces of a pulse of light masks any events that take place in the gap between the parts of the pulse, but if you tamper with the signal the gap shows up again."Link to Original Source
RedEaredSlider writes "The ritual of shoe removal has become familiar to air travelers flying inside and out of the United States, but most people still don’t like it. It takes time to do and slows down the security line.
Matthew Staymates of the National Institute of Standards and Technology in Gaithersburg, Maryland, thinks he and his colleagues might have developed a way around having every passenger remove shoes for screening. The trick is to pick up trace amounts of explosives. Staymates came up with a device that blows particles off surfaces and analyze them.
The air jets to blow the particles off the passenger’s shoe would be located in some strategic locations. One version of the device might be a kiosk-style contraption the passengers would step into (similar to the body scanners in use at many airports). The sampling system can collect particles in a few seconds."Link to Original Source
RedEaredSlider writes "One of the limitations of robot kits is that they can be complicated to use and build, and even the simplest ones require some hardware expertise. But now any smart phone can be a robot, thanks to the folks at Romotive.
The concept is quite simple: put a wheeled chassis on a smart phone or iPod Touch that allows for using the device as the “brain.” But that simplicity is what makes the robot, called Romo, powerful. Since the controls are contained entirely within the phone, they can be downloaded as apps. One can add new physical capabilities to Romo -– a claw, or a scoop -– but that doesn’t require any new additions to the phone.
Also, the controls are through the headphone jack. That simplifies the design and means that the robot doesn’t need to be linked with only one brand of smart phone."Link to Original Source
RedEaredSlider writes "Forget radio signals. Two scientists, Abraham Loeb, of Harvard University and Edwin Turner, from Princeton University, have said it may be possible with the next generation of telescopes to pick up the lights from cities on alien planets. On Earth, city lights are so bright they can be seen from space — and their spectral signature differs from that of the gases in the atmosphere and the sun. If one were looking at an alien civilization, one would expect to see the same thing.
The reason they proposed this is that aliens may not generate as much radio energy as their technology improves, given that on Earth we bleed less radio energy into space as we have moved to fiber optics."Link to Original Source
RedEaredSlider writes "Boston Dynamics, with funding from DARPA, has built a robot that simulates human movement and looks a lot like the Terminator. But it isn't designed for hunting down enemy soldiers — it's for testing out military equipment such as chemical and biohazard suits. By moving realistically it can test the suits without needing to call for volunteers."Link to Original Source
RedEaredSlider writes "Eddie, short for Expandable Development Discs for Innovation and Experimentation, is a robot platform developed by Microsoft that uses a Kinect, a DSLR camera as well as an array of infrared sensors to snap party pictures.
Eddie roams the room, looking for a person. Once it finds one, it gets them centered in the image and clicks the shutter. Though the potential for embarrassing shots here is pretty large, one question is what happens to the paparazzi at those big celebrity shindigs. It is a lot easier to control what a robot does and it won't care about a big payout from he tabloids — Kate Moss would have been safe from any revelations about (possible) drug use."Link to Original Source
