Scientists claim to have created a form of aluminum that's nearly transparent to extreme ultraviolet radiation and which is a new state of matter. It's an idea straight out of science fiction, featured in the movie "Star Trek IV." Fusion is a dream of scientists who would create cheap and plentiful power by fusing atoms together, as opposed to nuclear fission that generates electricity today.

Though it looks like a tiny purple blowtorch, a pencil-sized plume of plasma on the tip of a small probe remains at room temperature as it swiftly dismantles tough bacterial colonies deep inside a human tooth. It’s not another futuristic product of George Lucas’ imagination—it’s the exciting work of USC School of Dentistry and USC Viterbi School of Engineering researchers looking for new ways to safely fight tenacious biofilm infections in patients. Two of the study’s authors are Chunqi Jiang, a research assistant professor in the Ming Hsieh Department of Electrical Engineering-Electrophysics, and Parish Sedghizadeh, assistant professor of clinical dentistry...

THE plasma TV isn't dead yet -- but it looks like it's not long for this world. Like the Betamax videotape format and laser disc DVD before it, the plasma TV set -- the favorite of techies -- is losing out to the more popularly priced LCD TV. Pioneer and VIZIO -- the nation's No. 2 set maker -- say they're abandoning the plasma business. With a 22 percent sales drop in the first quarter of 2009 compared to last year -- when the sale of flat-screen TVs overall is sky rocketing -- "the writing is kind of on the...

In their continuing quest to reduce greenhouse gas emissions, state regulators have uncovered a new villain in the war on global warming : your big screen TV Couch potatoes, beware. The California Energy Commission is considering a proposal that would ban California retailers from selling all but the most energy-efficient televisions. Critics say the news standards could take 25 percent of televisions off the market — most of them 40 inches or larger. (snip) Affordable big screen TVs will still be available under the new standards, spokesman Adam Gottlieb said. In fact, he said the regulations will save you money....

In preparation for Sunday's Super Bowl showdown between the Pittsburgh Steelers and Arizona Cardinals, many football fans this weekend will buy or rent the biggest-screen TV they can get their paws on. Most of them, however, will be focusing on the picture quality rather than the impact on their electric bills of having an energy-guzzling mega-screen in their living rooms. But they might have no choice come this time next year: The California Energy Commission this summer is expected to adopt rules that would require retailers by 2011 to sell only TVs that meet federal Energy Star program standards, according...

Short on cash, some put a price on themselves Lean times spurs interest in payment for sperm, eggs, plasma — even hair By JoNel Aleccia Fri., Dec. 5, 2008 Before this fall, it might not have occurred to Michael Aylesworth to swap his sperm for money. But faced with rising bills, a dwindling budget and a fractured economy, the 30-year-old Seattle man took stock of some very personal assets — and decided to sell. “I did it because I’m a student and I’m always broke,” said Aylesworth, who spent several delicate minutes in a small room at the Seattle Sperm...

Researchers at the University of Illinois at Urbana-Champaign developed the microplasma transistor by integrating a conventional microcavity plasma device with an electron emitter. Kuo-Feng (Kevin) Chen and Professor J. Gary Eden, Director of the Laboratory for Optical Physics and Engineering, published their study in a recent issue of Applied Physics Letters. As Eden explained, a plasma transistor could one day have certain advantages compared with conventional transistors. "As you might imagine, this first plasma transistor has not yet been engineered to the degree necessary for a commercial product," Eden told PhysOrg.com. "Nevertheless, it should be mentioned that a microplasma transistor...

GAINESVILLE, Fla. — Flying saucers may soon be more fact than mere science fiction. University of Florida mechanical and aerospace engineering associate professor Subrata Roy has submitted a patent application for a circular, spinning aircraft design reminiscent of the spaceships seen in countless Hollywood films. Roy, however, calls his design a “wingless electromagnetic air vehicle,” or WEAV. The proposed prototype is small – the aircraft will measure less than six inches across – and will be efficient enough to be powered by on-board batteries. Roy said the design can be scaled up and theoretically should work in a much larger...

A Sacramento city councilwoman visited a Japanese energy plant last week to watch plasma torches vaporize garbage at temperatures hotter than the sun's surface. She returned more confident that the technology could help her hometown solve its garbage dilemma. "It's clearer than the Campbell's Soup plant," said Lauren Hammond, comparing the puff of white steam coming out of the Ushanti plasma gasification plant with that of the landmark factory on Franklin Boulevard. The Sacramento City Council will vote Tuesday on whether to continue negotiating with a Sacramento firm that wants to make California's capital the first American city to use...

Million-Degree Plasma Found in Orion 01/19/2008 The Orion nebula, an object of beauty to stargazers (picture, Hubble view) is pervaded by plasma heated to two million degrees Kelvin, reported astronomers in Science.1 Two funnel-shaped regions of x-ray emitting plasma in the extended nebula were observed by astronomers using the X-Ray Multi-Mirror (XMM)-Newton satellite. “The energy requirement to heat the large-scale x-ray emitting plasma is severe,” they said. What could heat up gas to emit 55 billion trillion trillion ergs per second? Not the molecular flows of gas in the nebula. Not the microjets from numerous young stars. Their suggestion: “The...

All current plasma TVs and many LCDs could be removed from sale by 2011. (File photo) (Reuters/Las Vegas Sun: Steve Marcus) A report commissioned by the Federal Government says there is a growing demand for plasma and LCD televisions, which use more power than traditional TV sets. It says energy rating labels are needed to tell consumers about the performance of the TVs. But under a proposed six-star rating system, most current plasma TVs do not meet the requirements and could be removed from sale. The report also suggests "minimum energy performance standards" be introduced which would eliminate the worst...

THE Conservatives will propose banning plasma screens and other energy-guzzling electrical goods in a report to be unveiled next week. The proposals target white goods like fridges and freezers, as well as TVs, personal computers and DVD players that use too much energy or operate on stand-by. The ideas come from a Conservative group set up by David Cameron to develop policies to protect the environment and although the measures to make household electrical appliances more energy efficient are not binding on Mr Cameron, they are thought likely to be warmly received by the Tory leader. The group will also...

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.

Imagine a car that accelerates from zero to sixty in 250 feet, and then rockets to 120 miles per hour in just one more inch. 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. The researchers—from the Department of Energy's Stanford Linear Accelerator Center (SLAC), the UCLA Henry Samueli School of Engineering and Applied Science, and the University of Southern California Viterbi School of Engineering—published their...

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...

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...

PowerPage.org 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"...

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.

Scientists have reacted angrily to the revelation that the US military is funding development of a weapon intended to deliver an "excrutiating bout of pain" from over a mile away. The "Pulsed Energy Projectile" (PEP) device "fires a laser pulse that generates a burst of expanding plasma when it hits something solid", the New Scientist explains. If you happen to be that something solid, then you get temporarily incapacitated without suffering permanent injury. That's the theory, but pain reasearchers fear that the proposed riot control weapon could be used for torture, and further doubt a solid ethical basis for the...

Nice TV, shame about the picture10:00 30 January 2005 Exclusive from New Scientist Print Edition Barry Fox If you are planning to buy one of the new ultra-wide flat-screen TVs, beware. On show in the shops, they bowl customers over with the sheer size of the images they display. But in many cases, once buyers get them home they quickly realise that the picture quality leaves a lot to be desired. This is because many flat-screen sets simply stretch pictures designed for smaller screens. Doing this makes the pictures' coarse line structure and low pixel count all too obvious. High-definition...

SAN DIEGO -- If you're light, it's fairly easy to travel at your own speed -- that is to say 186,282 miles per second or 299,800 kilometers per second. But if you are matter, then it's another matter altogether.Nothing we know of zips along more quickly than light. Einstein, nearly 100 years ago, said it's not possible. For us, the speed limit makes strange sense: Go faster than light, and you could return before you've left, become your own grandpa, or perform other leaps of cosmic logic.Fast forward a century.

Various companies are currently trying to perfect the technology behind a new type of flat-panel display that will rely on diamonds or carbon nanotubes--two forms of pure carbon--to produce images. Theoretically, these "field effect displays," or FEDs, will consume less energy than plasma or liquid crystal display (LCD) TVs, deliver a better picture and even cost less. The development of FEDs underscores the rapid changes taking place in what had been a relatively staid TV market.
