NASA Goes Hypersonic In X-43a TestEdwards (AFP) - Mar 27, 2004 
In what NASA says is a first for aviation an unmanned X-43A hypersonic research aircraft was dropped from a modified B-52 aircraft before rocketing away and firing up its revolutionary scramjet engine to push the "plane" to Mach 7. According to the latest information the X-43 broke the world speed aviation record, briefly flying at 7,700 kilometers (4,780 miles) per hour -- seven times the speed of sound, NASA said. Full report here. |

Bright Light Yields Unusual Vibes
Montreal - Mar 29, 2004By bombarding very thin slices of several copper/oxygen compounds, called cuprates, with very bright, short-lived pulses of light, Ivan Bozovic, a physicist at the U.S. Department of Energy's Brookhaven National Laboratory, and his collaborators have discovered an unusual property of the materials: After absorbing the light energy, they emit it as long-lived sound waves, as opposed to heat energy. Studying 3-D Materials In 1-D 
Montreal - Mar 29, 2004Research by Young-June Kim, a physicist at the U.S. Department of Energy's Brookhaven National Laboratory, may help determine how a class of materials already used in electronic circuits could be used in optical, or light-based, circuits, which could replace standard electrical circuits in telecommunications, computer networking, and other areas of technology. |
Rover Teams Prepare For Extended Mission
Pasadena - Mar 29, 2004NASA's Spirit will begin trekking toward hills on its eastern horizon in the next few days, entering a new phase of the rover's exploration of Mars just before its prime three-month mission ends and its extended mission begins, rover team members said today. Study Clarifies Evolutionary History Of Early Complex Single-Celled Life 
Tysons Corner VA - Mar 27, 2004A billion years ago (the Neoproterozoic age), complex single-celled organisms, the acritarchs, began to develop, grow, and thrive. Almost a billion years later, the study of the evolutionary history of acritarchs began to bog down amid inconsistencies in the diversity of species. |
Meteorological Information More Easily Available To Chinese Public
Beijing - Mar 29, 2004As a meteorological monitoring system consisting of 400 radars, 1,606 automatic meteorological stations and six satellites was put in place in China by the end of 2003, meteorological information becomes increasingly accessible to the Chinese society. Evicting Einstein 
Huntsville - Mar 29, 2004Sooner or later, the reign of Einstein, like the reign of Newton before him, will come to an end. An upheaval in the world of physics that will overthrow our notions of basic reality is inevitable and currently a horse race is underway between a handful of theories competing to be the successor to the throne. |
Docking With Precision
Houston TX - Mar 26, 2004The skills astronauts need to dock the Space Shuttle with the International Space Station (ISS) may be more familiar to school students than adults. The training simulator astronauts use to learn docking skills is found in many American homes; a video game console. ISS Crew Breathe Easy 
Washington - Mar 29, 2004The oxygen-producing Elektron unit aboard ISS continues to function well since it was restarted early last Saturday. Expedition 8 Commander Michael Foale and Flight Engineer Alexander Kaleri spent two days last week replacing a liquids unit and a water flow system of the Russian Elektron, in the Zvezda Service Module. The Elektron separates water into oxygen and hydrogen with oxygen used onboard, while the hydrogen is vented overboard. |
UK Eyes Key Role In Next Space Scope
London - Mar 29, 2004The Hubble Space Telescope has brought the wonder and spectacle of the Universe into every home. Its successor, the James Webb Space Telescope (JWST) due to be launched in 2011, will have a 6.5 metre diameter mirror - 2.5 times larger than Hubble's - enabling it to produce even sharper and more spectacular images from the farthest depths of the cosmos. Self-Assembling Proteins May Repair Tissue 
Baltimore - Mar 29, 2004Protein hydrogels can be genetically engineered to promote the growth of specific cells Johns Hopkins University researchers have created a new class of artificial proteins that can assemble themselves into a gel and encourage the growth of selected cell types. |
Type Of Buckyball Shown To Cause Brain Damage In Fish
Anaheim - Mar 29, 2004Researchers have found that a type of buckyball�a carbon nanoparticle that shows promise for electronic, commercial and pharmaceutical uses � can cause significant brain damage in fish. Composite Fibers With Carbon Nanotubes Offer Improved Properties 
Anaheim - Mar 29, 2004A new class of fibers Strong and versatile carbon nanotubes are finding new applications in improving conventional polymer-based fibers and films. For example, composite fibers made from single-walled carbon nanotubes (SWNTs) and polyacrylonitrile � a carbon fiber precursor � are stronger, stiffer and shrink less than standard fibers. |
