Our day-to-day lives exist in what physicists would call an electrically neutral environment. Desks, books, chairs and bodies don't generally carry electricity and they don't stick to magnets. But life on Earth is substantially different from, well, almost everywhere else. Beyond Earth's protective atmosphere and extending all the way through interplanetary space, electrified particles dominate the scene. Indeed, 99% of the universe is made of this electrified gas, known as plasma.
NASA's new Mars rover is heading for a risky do-or-die touchdown next month to assess conditions for life on the planet, but the U.S. space agency may not know for hours whether it arrived safely, managers said on Monday.
Forget videos of cute kittens or good deals on iPads. For the past few months, Google has been quietly turning its search capabilities to something far more challenging: criminals.
Through a labyrinth of hallways deep inside a 1950s-era building that has housed research that dates back to the origins of U.S. space travel, a group of scientists in white coats is stirring, mixing, measuring, brushing and, most important, tasting the end result of their cooking.
The flawless launch of the SpaceX Falcon 9 rocket on May 22, 2012 is another successful step for maxon motor ag in the use of high precision motors in the astronautics industry. The crucial tasks of the maxon motors in the SpaceX mission included orienting the solar arrays of the Dragon spacecraft towards the sun to provide the power supply.
Los Angeles (July 13 2012). Nuclear weapons testing may at first glance appear to have little connection with climate change research. But key Cold War research laboratories and the science used to track radioactivity and model nuclear bomb blasts have today been repurposed by climate scientists. The full story appears in The Bulletin of the Atomic Scientists, published by SAGE.
Fuel cells are inefficient because the catalyst most commonly used to convert chemical energy to electricity is made of the wrong material, a researcher at Case Western Reserve University argues. Rather than continue the futile effort to tweak that material - platinum - to make it work better, Chemistry Professor Alfred Anderson urges his colleagues to start anew.
Massive explosions on the sun unleash radiation that could kill astronauts in space. Now, researchers from the U.S. and South Korea have developed a warning system capable of forecasting the radiation from these violent solar storms nearly three hours (166 minutes) in advance, giving astronauts, as well as air crews flying over Earth's polar regions, time to take protective action.
Fire in enclosed military environments such as ship holds, aircraft cockpits and ground vehicles is a major cause of material destruction and jeopardizes the lives of warfighters. For example, a shipboard fire on the aircraft carrier USS George Washington in May 2008 burned for 12 hours and caused an estimated $70 million in damage.
Apple's withdrawal from an environmental ratings registry has prompted at least one city - San Francisco - to stop buying its computers.
Pluto may have been kicked out of the planet club, but it has gained yet another companion.
A team from the Navy Unmanned Combat Air System program office tested communication software for the Unmanned Combat Air System Carrier Demonstration (UCAS-D) program aboard the aircraft carrier USS Harry S. Truman (CVN 75) during its sea trials, July 7-10. The UCAS-D program, based at the Naval Air Systems Command (NAVAIR) on Naval Air Station (NAS) Paxutent River, Md., is designed to demonstrate the ability for the unmanned, autonomous X47-B unmanned air vehicle...
Honeywell announced the release of its new Basic Board Mount Pressure Sensors, NBP Series. These are a cost-effective, basic performance, mV output, unamplified, uncompensated, high quality, and high resolution solution for customers seeking high-volume, economical board mount pressure sensors.
Transducers USA has introduced their new piezo ceramic MLCT (Multilayer Ceramic Transmitter) series. Its unique simple acoustic multi-layer ceramic construction produces a high output of 80 Db with only 16V low driving voltage. Its milliwatt of power consumption and high conversion efficiency lead to an even broader range of applications.With an overall size of 30 X 20 X 1.5mm, the series is ideal for flat and narrow spaces.
Intelliconnect (Europe) Ltd. announced a complete range push-pull connectors that rival screw and locking types. The company states they offer panel designers space savings since there is no need for a coupling-tool or locking by hand and fast and easy mating and un-mating for
British mogul Richard Branson says he and his two children Holly and Sam will be on the first space flight of his Virgin Galactic venture next year.
So far, the scorecard for missions to Mars reads attempts 40, successes 14.
Scientists are using the world's biggest telescope, buried deep under the South Pole, to try to unravel the mysteries of tiny particles known as neutrinos, hoping to shed light on how the universe was made. The mega-detector, called IceCube, took 10 years to build 2,400 meters below the Antarctic ice.
Astronomers have puzzled over why some extremely faint dwarf galaxies spotted in our Milky Way galaxy's backyard contain so few stars. The galaxies are thought to be some of the tiniest, oldest, and most pristine galaxies in the Universe. They have been discovered over the past decade by astronomers using automated computer techniques to search through the images of the Sloan Digital Sky Survey.
I recently read a report that the Department of Defense received over 80,000 counterfeit components from a now-defunct Shenzhen-based broker named "Hong Dark Electronics." After reading this, I felt two things: amusement and terror. I felt amusement that the DoD has been authorizing purchases from a Shenzhen-based broker (and in turn receiving various types of counterfeit components)...
W. L. Gore & Associates has developed new cable-based antennas (often referred to as leaky lines or leaky feeders) that improve signal propagation without increasing the amount of hardware required on an airplane. Ideal for both wide-body and single-aisle passenger aircraft, GORE Cable-Based Antennas provide reliable access to different wireless protocols so passengers can easily connect to in-flight entertainment, Internet servers, and email accounts
Teseq has introduced a new magnetic field coil that generates fields up to 1200 A/m during magnetic field testing.
ICP DAS USA, Inc. introduced I-7540D-WF, its CAN to Wi-Fi Converter, which will allow CAN bus devices to communicate with other CAN bus devices over wireless Wi-Fi networks.
An advanced telescope imaging system that started taking data last month is the first of its kind capable of spotting planets orbiting suns outside of our solar system. The collaborative set of high-tech instrumentation and software, called Project 1640, is now operating on the Hale telescope at the Palomar Observatory in California after more than six years of development by researchers and engineers at the American Museum of Natural History, the California Institute of Technology, and the Jet Propulsion Laboratory (JPL). The project's first images demonstrating a new technique that creates extremely precise "dark holes" around stars of interest were presented today at the International Society for Optics and Photonics (SPIE) Astronomical Telescopes and Instrumentation meeting in Amsterdam by Ben R. Oppenheimer, an associate curator in the Museum's Department of Astrophysics and principal investigator for Project 1640.
Polonium first hit the headlines when it was used to kill KGB agent-turned-Kremlin critic Alexander Litvinenko in London in 2006. This week, Yasser Arafat's widow has called for the late Palestinian leader's body to be exhumed after scientists in Switzerland found elevated traces of radioactive polonium-210 on clothing he allegedly wore before his death in 2004.
