    From zebra stripes to a honeycomb lattice, nature features breathtaking patterns. Now, physicists based in China have found a way to recreate these natural motifs in 3-D — using just a little electricity. Their new device discharges plasma — air and argon gas charged with electricity — or the same stuff found in neon lights. Using different voltages, the researchers were able to create various 3-D shapes in the plasma. “To experts, this work could advance the development of plasma physics,” co-inventor Lifang Dong of Hebei University told the NewsHour. “But to non-experts, it could explain a whole range of...

UM Professor Daniel Reisenfeld is a member of the Cassini research team... One of the instruments on Cassini measures the planet's magnetosphere - the charged particles, known as plasma, that are trapped in the space surrounding Saturn by its magnetic field. One of Cassini's past discoveries is that Saturn's plasma comprises water ions, which are derived from Saturn's moon Enceladus, which spews water vapors from its Yellowstone-like geysers. Knowing that the water ions would not be able to accumulate indefinitely, the team of...

    Researchers could be one step closer to producing energy through nuclear fusion with word that a device called the stellarator is set to go online later this year in Germany. The largest contraption its kind, the Wendelstein 7-X fusion device is housed in a branch of the Max Planck Institute for Plasma Physics (IPP) near Munich. It won’t actually produce energy, the Institute said, but will be used to test the “specially shaped magnet coils which produce a magnetic cage which confines the plasma and keeps it away from the walls of the plasma vessel.”

    If you think the image above looks frightening, you’re right. The crazy contraption pictured in the image is the first portable railgun, a futuristic projectile launcher associated most commonly with the military or NASA. The man in the image above isn’t in the military, and he’s not a NASA engineer. Instead, he’s a civilian who used some engineering smarts, some widely available parts and a 3D printer to create a functioning weapon that can fire graphite, aluminum, tungsten and even plasma projectiles at speeds of more than 560 mph. And then there’s the best part: There are videos of this...

    US researchers have developed a new way to create glowing orbs of plasma similar to ball lightning in the lab, allowing them to study their chemical and physical properties. The work could help scientists unravel the mysteries of this very rare natural phenomenon.Ball lightning has been known for millennia, but its rarity and short lived nature – typically lasting between 1 and 10 seconds – has prevented it from being studied and understood. In recent years, however, lab experiments that mimic ball lightning have been developed.One method involves a glowing discharge produced above an aqueous electrolyte solution. However, high...

    Governments should tax plasma screen televisions because of the large amount of energy they consume, according to a leading expert on climate change. Professor Paul Ekins, who studies the economics of climate change, said taxing plasma screens would reflect their "greater climate change burden". This would encourage development and take-up of more energy efficient diode screens, Professor Ekins said. He said government could label energy hungry appliances as a first step. Plasma televisions, which are 50% bigger than their cathode-ray tube equivalents, consume about four times more energy, according to the government-funded Energy Saving Trust.

That's essentially what a collaboration of accelerator physicists has accomplished, using electrons for their racecars and plasma for the afterburners. Because electrons already travel at near light's speed in an accelerator, the physicists actually doubled the energy of the electrons, not their speed.

    There are many reasons to buy an HDTV now. 1) Your team could be good this year. 2) There’s more stuff on high-definition TV than ever. 3) Prices are dropping. If you’re looking, here are some things you should know: DLP •Millions of tiny mirrors reflect light to produce a picture. You can recognize DLP (digital light processing) sets in the store: They’re the big, boxy televisions. LCD •Electrically charged liquid crystals untwist just enough to let the correct shade of light pass through. PLASMA •Bits of gas are ignited to produce light. FAQs Which is better, LCD or plasma?...
  • China to test its 'artificial sun'

    BEIJING, July 24 (UPI) -- The first plasma discharge from China's experimental advanced superconducting research center -- the so-called "artificial sun" -- is set to occur next month. The discharge, expected about Aug. 15, will be conducted at Science Island in Hefei, in east China's Anhui Province, the Peoples Daily reported Monday. Scientists told the newspaper a successful test will mean the world's first nuclear fusion device of its kind will be ready to go into actual operation, the newspaper said. The plasma discharge will draw international attention since some scientists are concerned with risks involved in such a process....

    Ball lightning – the mysterious slow-moving spheres of light occasionally seen during thunderstorms – has been created in the lab. Researchers at the Max Planck Institute for Plasma Physics and the Humboldt University in Berlin have used underwater electrical discharges to generate luminous plasma clouds resembling ball lightning that last for nearly half a second and are up to 20 centimetres across. They hope that these artificial entities will help them understand the bizarre phenomenon and perhaps even provide insights into the hot plasmas needed for fusion power plants. You can watch a super-slow-motion video of the ball lightning here...

    Sandia National Laboratories has developed a machine that produces plasmas that exceed temperatures of two billion degrees Kelvin -- hotter than the interiors of stars, the Labs' scientists say. The principle mission of the "Z machine" was to create a high radiation output environment through which to test computer codes responsible for maintaining a safe and reliable nuclear weapons stockpile. The results of the tests show the machine accomplishes just that. But, the hot outputs, the unexpected results of a non-nuclear reaction, might be able to explain how astrophysical entities like solar flares maintain their extreme temperatures. The energy also...

    The night sky could soon be lit up with gigantic three-dimensional adverts, thanks to a Japanese laser display that creates glowing images in thin air. The system is being developed by the National Institute of Advanced Industrial Science and Technology (AIST) in Tokyo, in collaboration with Burton Inc and Keio University. “We believe this technology may eventually be used in applications ranging from pyrotechnics to outdoor advertising,” says a spokesman for AIST. According to Burton Inc, the technology might also be used for emergency distress signals or even temporary road signs. The display utilises an ionisation effect which occurs when...
  • Agreement to Commercialize Advanced NASA Rocket Concept

    NASA has signed an agreement with Houston-based Ad Astra Rocket Co. that paves the way for commercialization of a promising advanced plasma rocket system that has evolved over the past 25 years. The Variable Specific Impulse Magnetoplasma Rocket (VASIMR) is a type of propulsion system that produces a plasma exhaust at temperatures similar to those in the interior of the sun. The system may generate rocket thrust with performance hundreds of times higher than that of present chemical rockets. The increased performance could mean dramatic reductions in fuel requirements. While conventional rocket nozzles would melt under the extreme temperatures, VASIMR...

    The wraps came off high-definition DVD players at this year's annual Consumer Electronics Show, offering the final component to replicate the movie theater experience at home. And while a fierce DVD format war likely will delay the mass adoption of such devices, digital video is here to stay - the Consumer Electronics Association trade group estimates 25 million U.S. homes will have a high-def TV set by year's end. But big, expensive flat-panel sets aside, this year's gadget show offered plenty of smaller screens for video... Yahoo Inc., DirecTV, Starz Entertainment Group and Sony were also among the companies getting...
  • Apple to Announce 42'' and 50'' Plasma Viiv Displays?

    01/06/2006 11:36:55 PM PST · by Panerai · 15 replies · 651+ views
    Mac Rumors ^ | 01/06/2006 posts an unusual report claiming that Apple would be releasing 42inch and 50inch Plasma Displays at Macworld San Francisco. That possibility alone would be quite unusual for Apple, but the report describes that the new plasma displays will be powered by Intel's recently announced Viiv multimedia platform running Mac OS X 10.4.4 for x86 (Intel). Prices for the displays/computers are reportedly $2599 and $3299. The report is unusual in that it is written as a story, presumably to hide the source of the information. Of note, ThinkSecret has recently suggested that Apple will be releasing a larger than 30"...

    Gizmos land among CES 'mega-trends' as U.S. sales rocket It's all about portable music players and flat-panel TVs. One look around the floor of the Las Vegas Convention Center confirms that, with much of the space devoted to companies pitching all manner of MP3 devices and big- screen televisions. And no wonder - U.S. shipping revenues of portable MP3 players in the first 11 months of last year were up 224 percent over 2004. And sales of flat-panels - LCD and plasma sets - are expected to go from $6 million in 2005 to $10 million this year, helped by...

    The 'double layer thruster' is a new kind of ion drive which could give much more power than existing versions. It works by accelerating charged particles between two layers of argon plasma, gas where the atoms have been stripped of electrons. Esa says it has 'proven the principle', and will proceed with simulations and perhaps bigger prototypes. Esa already uses an ion drive on its Smart 1 Moon probe, and the US space agency Nasa deployed one on Deep Space 1, which flew out to Comet Borrelly in 2001.
