Replacement for aging doppler radar being tested

longacre writes "Due to its limited range and slow scan times, the backbone of weather prediction in the US since the early 1990s, the NEXRAD radar system, is deeply flawed in the eyes of meteorologists. A new system being tested by researchers at the NOAA and four universities called the Collaborative Adaptive Sensing of the Atmosphere (CASA) network aims to fill the holes left by NEXRAD, using radar nodes piggybacked onto existing infrastructure, such as rooftops and cell towers. From the article: 'Based on faster and more comprehensive data collection, [Distributed Collaborative Adaptive Sensing] processing can refocus the CASA radars on a particularly interesting part of a storm (like an area that looks like it might develop a tornado) without losing track of an entire storm cell. "The system is continuously diagnosing the atmosphere and reallocating resources using wireless Internet as a backbone," says [the CASA team director].' Testing has begun in Oklahoma, Houston, and Puerto Rico, and initial installations could begin in 5 years."

Linux cluster supercomputer performs surgery on dog

An anonymous reader writes "In April, the Lonestar supercomputer, a Dell Linux Cluster with 5,840 processors at the Texas Advanced Computing Center in Austin, performed laser surgery on a dog in Houston without the intervention of a surgeon. The article describes the process: 'The treatment itself is broken into four stages: 1) Lonestar instructs the laser to heat the domain with a non-damaging calibration pulse; 2) the thermal MRI acquires baseline images of the heating and cooling of the patient's tissue for model calibration; 3) Lonestar inputs this patient-specific information and recomputes the optimal power profile for the rest of the treatments; and 4) surgery begins, with remote visualizations and evolving predictions continuing throughout the procedure.'"

A home lab/shop for kids?

sharp-bang writes "When I was growing up, my Dad let my brother and I have the run of his wood shop, and kept up a steady stream of Lego kits, Estes model rockets, chemistry sets, Heathkit projects, and other fun science stuff from the Edmund Scientific catalog, and the rest was history. I'd like to give my kids that kind of experience. If your kids were interested in science, computers, robots, and building stuff, how would you build and outfit a lab/shop for them (and you) to play in?"

Swarming ants destroy electronics in texas

AntOverlords writes "Voracious swarming ants that apparently arrived in Texas aboard a cargo ship are invading homes and yards across the Houston area, shorting out electrical boxes and messing up computers. They have ruined pumps at sewage pumping stations, fouled computers and at least one homeowner's gas meter, and caused fire alarms to malfunction. They have been spotted at NASA's Johnson Space Center and close to Hobby Airport, though they haven't caused any major problems there yet."

Rocket racing league ready to launch

capnkr sends us to Wired for the story of the long-delayed Rocket Racing League, which we discussed when it launched in 2005. It seems the league is finally ready to get off the ground. At a press conference at the Yale Club in New York, RRL CEO Granger Whitelaw said rocket-powered planes will fly their first exhibition race in August at the EAA AirVenture air show in Oshkosh, Wisconsin, with at least three more races to follow in 2008. "The Rocket Racing League on Monday detailed plans to move from a sci-fi fantasy to a full-fledged commercial enterprise — including 'vertical drag races' using rockets."

Mysterious sound waves can destroy rockets

Ponca City, We love you writes "Scientists believe that powerful and unstable sound waves, created by energy supplied by the combustion process, were the cause of rocket failures in several US and Russian rockets. They have also observed these mysterious oscillations in other propulsion and power-generating systems such as missiles and gas turbines. Now, researchers at the Georgia Institute of Technology have developed a liquid rocket engine simulator and imaging techniques to help demystify the cause of these explosive sound waves and bring scientists a little closer to being able to understand and prevent them. The team was able to clearly demonstrate that the phenomenon manifests itself in the form of spinning acoustic waves that gain destructive power as they rotate around the rocket's combustion chamber at a rate of 5,000 revolutions per second. Researchers developed a low-pressure combustor to simulate larger rocket engines then used a very-high-speed camera with fiber optic probes to observe the formation and behavior of excited spinning sound waves within the engine. 'This is a very troublesome phenomenon in rockets,' said Professor Ben Zinn. 'These spinning acoustic oscillations destroy engines without anyone fully understanding how these waves are formed. Visualizing this phenomenon brings us a step closer to understanding it.'"

Spread your ashes on the moon

Celestis Inc., has pioneered the sending of cremated remains into suborbital space on rockets and now it wants to start a service that would send your ashes to the surface of the moon. The new service starts at $10,000 for a small amount of ashes from one person and could begin as early as next year. The Company currently offers a service that will spread your ashes on the sound stage where the original moon landing was shot for $100.

Nasa's new lunar rover in action

holy_calamity writes "New Scientist has video of Nasa's new Chariot lunar rover in action on simulated moon surface in Houston. As the associated story explains, the two-ton "truck" has a top speed of 20km/hour and is currently fitted with a plough, with additional back hoe and drill attachments to come. Sure it's not glamorous — more of a lunar tractor — but sure looks handy for establishing that permanent moon base NASA wants."

Municipal wifi moves ahead in houston

Highlander404 sends word of one city that is bucking the trend of failing city Wi-Fi projects: Houston is investing most of the $5 million Earthlink paid to get out of its muni Wi-Fi contract to build out 10 free wireless network "bubbles" in low-income parts of the city. Access points will be in city-owned facilities to keep costs down. Houston's mayor said that over the long term the bubbles could be connected and the areas between them added to the network. The activation of the first of these zones was announced Monday. Upload and download speeds are said to be 3 Mbps.

Space planes to meet 'big demand' for tourism

Mab_Mass writes "Widespread space tourism is getting closer to reality, reports the BBC. In fact, Aerospace company EADS sees that sector of the tourism market being so lucrative that it will need a 'production line' of rockets to satisfy the needs of rich travelers. '[EAD's] market assessment suggests there would be 15,000 people a year prepared to part with some 200,000 euros (£160,000) for the ride of a lifetime. [EADS subsidiary] Astrium anticipates it be will be producing about 10 planes a year.'"
