Cree Introduces 200 Lumen/Watt Production Power LEDs

ndverdo writes “Cree just announced production power LEDs reaching 200 lumen/watt. Approximately doubling the previous peak LED light efficiency, the new LEDs will require less cooling. This should enable the MK-R series to finally provide direct no-hassle replacements to popular form-factors such as MR-16 spots and incandescent lighting in general. The LEDs are sampling and it is stated that ‘production quantities are available with standard lead times.'” Read more of this story at Slashdot.

Magnetically lifted graphite moves by laser, may lead to light-based maglev vehicles (video)

Magnetic levitation is central to the fastest trains we know today, but it’s that dependence on electromagnets and rails that limits how and where it’s used for transportation. Aoyama Gakuin University has a unique alternative: changing the material properties themselves. By floating graphite over a bed of circular magnets, taking advantage of its tendency to generate an opposing magnetic field, researchers can move the graphite just by blasting its edge with a laser. The heat skews the magnetic behavior of that area enough to unbalance the graphite, either in a specific direction or a spin. The research team believes it could lead to maglev transportation or even energy converting turbines that are steered solely by light, with no contact or outside guides: maglev vehicle pilots could have much more control over where they go. Getting to that point will require a much larger scale, but successful development could give technology a very literal lift.

World’s Longest High-Speed Rail Line Opens In China

An anonymous reader writes “Today China continued rolling out the future of high speed rail by officially unveiling the world’s longest high-speed rail line — a 2,298-kilometer (1,428-mile) stretch of railway that connects Beijing in the north to Guangzhou in the south. The first trains on the new route hit 300 kph (186 mph), cutting travel time between the two cities by more than half.” Read more of this story at Slashdot.

California’s marijuana boom is wreaking havoc on the environment

The Los Angeles Times is reporting that the dramatic rise in pot farms in Northern California is starting to take a toll on the surrounding environment. Agricultural practices like water-siphoning, pesticide spraying, and littering are having a noticeable effect on what is a very fragile ecosystem. More »

FDA Closer To Approving Biotech Salmon

An anonymous reader writes with a story about the possibility of genetically engineered salmon showing up on your table. “A controversial genetically engineered salmon has moved a step closer to the consumer’s dining table after the U.S. Food and Drug Administration said Friday the fish didn’t appear likely to pose a threat to the environment or to humans who eat it. AquAdvantage salmon eggs would produce fish with the potential to grow to market size in half the time of conventional salmon. If it gets a final go-ahead, it would be the first food from a transgenic animal – one whose genome has been altered – to be approved by the FDA.” Read more of this story at Slashdot.

Bee Venom Has “Botox-Like Effect,” Is Worth 7 Times As Much As Gold

dryriver writes “The BBC reports that cosmetic products using Bee Venom as an ingredient are a new ‘hot seller’ in the cosmetics market. Bee venom is said to have an effect on female skin similar to Botox injections, tightening the skin and making wrinkles and other signs of aging appear less pronounced than before. Unlike Botox, however, bee venom does not need to be injected, and can be absorbed through the skin naturally as an ingredient of cosmetic skin creme. Now comes the kicker: A special electrified device that causes bees to sting a synthetic membrane and release their venom can harvest about one gram of bee venom from 20 bee hives. That one gram of bee venom is worth a whopping 350 dollars. This makes Bee Venom almost seven times more valuable than Gold, which, in comparison, is worth only about 53 Dollars per 1 gram.” Read more of this story at Slashdot.

Typingpool: Human Audio Transcription Parallelism

theodp writes “Silly rabbit, parallel processing is not just for Big Data! Building on techniques outlined by Andy Baio back in 2008, Wired writer and 20% Doctrine evangelist Ryan Tate has released Ruby-based software called Typingpool to make audio transcriptions easier and cheaper. ‘Typingpool chops your audio into small bits and routes them to the labor marketplace Mechanical Turk,’ Tate explains to his reporter pals, ‘where workers transcribe the bits in parallel. This produces transcripts much faster than any lone transcriber for as little one-eighth what you pay a transcription service. Better still, workers keep 91 percent of the money you spend.’ Remember to Use the Force for Good, Tate adds.” Read more of this story at Slashdot.

Acquire a transhuman Compass Sense with a kit-built anklet

The North Paw is a kit for an anklet that subtly vibrates your on the side of your ankle that faces north, so that you attain a kind of subliminal “Compass Sense” like those possessed by certain birds. What makes it way more awesome than a regular compass? Persistence. With a regular compass the owner only knows the direction when he or she checks it. With this compass, the information enters the wearer’s brain at a subconscious level, giving the wearer a true feeling of absolute direction, rather than an intellectual knowledge as with a regular compass. Because of the plasticity of the brain, it has been shown that most wearers gain a new sense of absolute direction, giving them a superhuman ability to navigate their surroundings. The original idea for North Paw comes from research done at University of Osnabrück in Germany. In this study, rather than an anklet, the researchers used a belt. They wore the belt non-stop for six weeks, and reported successive stages of integration. North Paw ( Thanks, Lucas )
