Elephant seals wearing head sensors and swimming deep beneath Antarctic ice have helped scientists better understand how the ocean's coldest, deepest waters are formed, providing vital clues to understanding its role in the world's climate.
Beijing hotly denies accusations of official involvement in massive cyberattacks against foreign targets, insinuating such activity is the work of rogues. But at least one piece of evidence cited by experts points to professional cyberspies: China's hackers don't work weekends.
Dire warnings from Washington about a "cyber Pearl Harbor" envision a single surprise strike from a formidable enemy that could destroy power plants nationwide, disable the financial system or cripple the U.S. government. But those on the front lines say it isn't all about protecting U.S. government and corporate networks from a single sudden attack. They report fending off many intrusions at once from perhaps dozens of countries, plus well-funded electronic guerrillas and skilled criminals.
The White House has moved to make the results of federally funded research available to the public for free within a year, bowing to public pressure for unfettered access to scholarly articles and other materials produced at taxpayers' expense."Americans should have easy access to the results of research they help support," John Holdren, the director of the White House Office of Science and Technology Policy, wrote on the White House website.
Crystek’s new CVCO55CXT-5580-5685 Coaxial Resonator Oscillator (CRO) is a coaxial-based VCO with an internal proprietary frequency doubler. The CVCO55CXT family’s frequency doubling, 2X fundamental technology reaches new performance levels of lower phase noise and much lower harmonics over the competition, while achieving lower current consumption in the process.
(Reuters) - India will launch its first mission to Mars this year, President Pranab Mukherjee said on Thursday, as the emerging Asian nation looks to play catch up in the global space race alongside the United States, Russia and its giant neighbor China.
"Star Trek" star William Shatner and tens of thousands of the show's fans are leading a charge to name one of Pluto's newly discovered moons after the character Spock's home planet. Shatner, who played Captain James T. Kirk on the Starship Enterprise on the program launched in 1966, proposed the name earlier this month in response to an appeal from scientists for help in choosing the names of two newly discovered Pluto moons.
Inclination sensors provide precise precision control, continuous positioning of rotational movementsFebruary 21, 2013 4:31 pm | Balluff Inc. | Product Releases | Comments
Balluff's new liquid-based inclination sensors measure the deviation on a horizontal axis of up to 360°. With an extremely high accuracy of 0.1°C, a resolution of 0.01° and a temperature drift of just 0.01% /10K, they are the ideal choice for solar -thermal power plant and renewable energy applications that require angle measurement or constant rotary monitori
Craig Underwood of Surrey Space Centre, University of Surrey, gives his talk titled 'The Micro/Nano-Satellite Revolution'. Recorded at NPL on 19 February 2013.
By studying the origins of different isotope ratios among the elements that make up today's smorgasbord of planets, moons, comets, asteroids, and interplanetary ice and dust, Mark Thiemens and his colleagues hope to learn how our solar system evolved.
An international team of astronomers has used nearly three years of high precision data from NASA's Kepler spacecraft to make the first observations of a planet outside our solar system that's smaller than Mercury, the smallest planet orbiting our sun.
Since when did waggling a joystick become more valorous than pulling a trigger? It hasn’t, you say? The newly-minted Distinguished Warfare Medal — created to honor cyberwarriors and drone pilots — would rank above the Bronze Star and Purple Heart, and the military community is incensed.
Tecnalia is participating in the SECUREMETRO project which is aimed at the development and investigation of protective systems for metro vehicles that can enable us to travel with a greater level of safety in the case of a disastrous event.
Scientists have found more than 50 tiny fragments of a meteor that exploded over Russia's Ural Mountains, and preliminary tests are turning up information about its contents. However, local residents seem more interested in the black market value of the fragments. As they search for their own pieces of the meteor, sales offers already are filling the Internet, and police are warning all purchasers to prepare for possible fraud.
Take that, free world! For all you naysayers out there who thought Iran’s clown car, er ... stealth fighter ... smelled a bit fishy, the Islamic Republic has the ultimate retort: a badly-Photoshopped image of the Qaher-313 set against stock photo #3.
The Pentagon said it plans to continue using lithium-ion batteries on the new F-35 fighter jet despite problems with similar batteries that have grounded Boeing Co's new 787 airliner and are causing Airbus to rethink their use on its A350 jet. Joe DellaVedova, spokesman for the Pentagon's $396 billion F-35 program office...
NASA is set to launch a new Earth-observing satellite designed to carry on the tradition of documenting changes to the planet's glaciers, forests and coastlines. Mission managers gave the OK earlier this week to proceed with Monday's launch. The Landsat satellite was scheduled to be lifted into orbit from the Vandenberg Air Force Base in California aboard an Atlas V rocket.
You can call it a snowstorm of historic proportions. You can call it the return of New England's blizzard of 1978. You can call it simply dangerous. And you can even call it Nemo. But don't call it hype. The new director of the National Weather Service says some may be getting carried away in describing the winter storm bearing down on the Northeast. But he says the science is simple and chilling.

Three NASA scientists teamed up to develop and demonstrate NASA's first wide-field-of-view soft X-ray camera for studying "charge exchange," a poorly understood phenomenon that occurs when the solar wind collides with Earth's exosphere and neutral gas in interplanetary space.
"Watson," no, not Sherlock's sidekick, but the famous supercomputer who beat the world's best human at Jeopardy, is going back to school. IBM is sending the Watson system to Rensselaer Polytechnic Institute, so it can improve its "thinking" skills. Because making robots more human always works out just fine.
So it turns out that the new Iranian stealth fighter may be as genuine as the Islamic Republic’s concern for human rights. The regime unveiled the jet, 'Qaher 313', on Saturday, and the blogosphere immediately went to work debunking what could be one of the laziest forgeries of all time.
Holt Integrated Circuits today announced the introduction of HI-8435, a new 3.3V, 32-channel, discrete-to-digital sensing IC with SPI interface and built-in lightning protection. The sense input thresholds and hysteresis are programmable via the 20MHz SPI bus and all 32 sense output states may be read with a single SPI command.
Jay Leno's garage is known for some of the most impressive vehicles in the world, and parked inside was the Army Materiel Command's Fuel Efficient Demonstrator here, Feb. 4. Gen. Dennis L. Via, commanding general of Army Materiel Command, and Grace Bochenek, AMC's chief technology officer, showcased the Fuel Efficient Demonstrator, or FED, on Leno's Internet car show called Jay Leno's Garage.
A pair of big, blimp-like craft, moored to the ground and flying as high as 10,000 feet, are to be added to a high-tech shield designed to protect the Washington D.C. area from air attack, at least for a while.The bulbous, helium-filled "aerostats" - each more than three quarters the length of a football field at 243 feet
