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.'"

Fletch writes "FCC Chairman Kevin Martin could be in for an uncomfortable spring, as House Energy Committee Chair John Dingel (D-MI) has requested a truckload of FCC paperwork relating to some controversial decisions Martin has made. Those include the FCC's reversal on the a la carte cable issue and newspaper-television cross-ownership restrictions. 'This request has got to be turning the FCC completely upside down. Significantly, it appears to reflect a bipartisan discontent with Martin's performance. Democrats and some Republicans are upset over his recent move to relax one of the agency's key media ownership rules, as well as the rushed manner in which he handled the matter late last year. Other Republicans dislike what they see as Martin's persecution of the cable industry, especially Comcast.' The Committee originally announced its intention to investigate the FCC in January."

An anonymous reader writes "Animals use pheromones to attract each other for sex, and warn each other of danger. Now, Wired reports, military researchers are working to harness the 'human fear' pheromone to create a scent of terror. The pheromone could lead to smell-based terrorist sensors, and new weapons that rely on 'contagious' stress."

Richard Pritches writes in to let us know that MIT errata expert Evangelos Georgiadis has disproved 44 conjectures set by Dr. Stephen Wolfram (founder of Mathematica) in A New Kind of Science. The paper was published in the latest issue of the Journal of Cellular Automata and can be read in PDF form at Prof Edwin Clark's collection of reviews of Wolfram's ANKS. "The formulas provided by Wolfram for these [44] rules are not minimal. Moreover for 8 of these cannot be minimal even by simple inspection since minimal formula sizes for 3-input Boolean functions over this basis never exceeds 5."

Lucas123 writes "Proteus, a Wave Adaptive Modular Vessel that looks like a spider, is so fuel efficient that it can travel 5,000 miles on one load of diesel fuel. The 100-foot-long, 50-foot-wide boat rides on metal and fabric pontoons that have hinges and shock absorbers to flex with the motion of the waves, which helps it to skim over the water at a max speed of 30 knots. It made its debut yesterday in New York harbor."

SonicSpike writes " NASA has discovered a chunk missing from the underside of the space shuttle Endeavour. It was discovered after the shuttle docked with the ISS earlier today. Technicians theorize it may have been caused by ice ripping free of a fuel take during takeoff. From the article:'The gouge — about 3 inches square — was spotted in zoom-in photography taken by the space station crew shortly before Endeavour delivered teacher-astronaut Barbara Morgan and her six crewmates to the orbiting outpost ... On Sunday, the astronauts will inspect the area, using Endeavour's 100-foot robot arm and extension beam. Lasers on the end of the beam will gauge the exact size and depth of the gouge, Shannon said, and then engineering analyses will determine whether the damage is severe enough to warrant repairs. Radar images show a white spray or streak coming off Endeavour 58 seconds after liftoff. Engineers theorize that if the debris was ice, it pierced the tile and then broke up, scraping the area downwind. Pictures from Friday's photo inspection show downwind scrapes."

SkiifGeek writes "Many anti-malware applications use a sandbox as a tool to help identify potentially malicious software. Now knowledge is spreading about techniques and methods that can allow sandboxed software to target the sandbox itself (and by extension the application that applied it). While attacks that specifically target sandboxing applications are probably a little way off, this technology can be considered the logical extension of techniques and procedures to identify the presence of hosted systems (VMWare, Virtual PC, etc.)."

netbuzz writes "SAP's CEO Henning Kagermann uses the undoubtedly lawyered term 'inappropriate download' to describe the company's questionable actions. Henning blames a rogue business unit, but there can be no mistaking the fact that Oracle caught SAP with its hand in the IP jar on this one. The legal proceedings that will follow should prove interesting. 'The admission hurts SAP's reputation in the battle with Larry Ellison's Oracle in the $56 billion market for software that manages tasks such as payroll. The rivalry between SAP and Oracle escalated when Oracle filed its March 22 lawsuit claiming SAP workers hacked into a Web site and stole software codes on a grand scale.'"

With the iPhone release coming soon there is no shortage of stories being submitted. Here is an overview of all of its features and specifics on its technical workings. A list of applications is out and still growing. There are warnings however that some applications and peripherals won't be ready or compatible in time for the release. Finally with all the hype associated with the iPhone, we have a reminder of some previous Apple products that ended with a whimper instead of a roar.

cyrusmack writes "Hot on the heels of the bad news regarding the defeat of all open formats bills, New York has become the latest in an area that has seen a flurry of activity already this year. In the article on InfoWorld, it's pretty clear that this bill is significantly watered down from what other states have attempted to do this year. You can bet Microsoft will be there in force, just as it has been elsewhere."

CptRevelation writes "Microsoft has released more detailed information on the patents supposedly in breach by the open-source community. Despite their accusations of infringement, they state they would rather do licensing deals instead of any legal action. 'Open-source programs step on 235 Microsoft patents, the company said. Free Linux software violates 42 patents. Graphical user interfaces, the way menus and windows look on the screen, breach 65. E-mail programs step on 15, and other programs touch 68 other patents, the company said. The patent figures were first reported by Fortune magazine. Microsoft also said Open Office, an open-source program supported in part by Sun Microsystems Inc., infringes on 45 patents. Sun declined to comment on the allegation.'"

Tomorrow is Mother's Day in the US, and Newsweek's N'Gai Croal rightly estimates that many gamers owe a lot to their mothers. Because they indulged what they likely initially saw as a strange choice of hobby, we have a thriving gaming industry to enjoy today. The Level Up site offers an interview with a woman on the Newsweek staff who learned to tolerate those 'console things', and another piece where N'Gai interviews his own mom about his games-related past. "N'Gai: Growing up, you allowed us kids to have a computer, but we weren't allowed to have a videogame machine. What was your thinking behind that? Yvonne Croal: Well, in my estimation at that time, videogames were just another silly game. We certainly didn't want you to be spending 24/7 playing these games that we considered not productive in any way." If you're still looking for a gift for your own mom, Pop Cap is giving away a free copy of Bejeweled to anyone that signs up for their newsletter. Worked on my mom. Happy Mother's Day.

ghostcorps recommends a writeup in The Australian by columnist Phillip Adams about a new windmill design that extracts water from air. The article gives few details of how it works, because patent protection is not yet in place, but what is revealed sounds promising. "[Max] Whisson's design has many blades, each as aerodynamic as an aircraft wing, and each employing 'lift' to get the device spinning... They don't face into the wind like a conventional windmill; they're arranged vertically, within an elegant column, and take the wind from any direction... The secret of Max's design is how his windmills, whirring away in the merest hint of a wind, cool the air as it passes by... With three or four of Max's magical machines on hills at our farm we could fill the tanks and troughs, and weather the drought. One small Whisson windmill on the roof of a suburban house could keep your taps flowing. Biggies on office buildings, whoppers on skyscrapers, could give independence from the city's water supply. And plonk a few hundred in marginal outback land — specifically to water tree-lots — and you could start to improve local rainfall."

XorNand writes "With the explosive growth of the Web in the previous decade, many predicted the birth of a new, well-paying, and in-demand profession: the Webmaster. Yet in 2007, this person has somehow vanished; even the term is scarcely mentioned. What happened? A decade later I'm left wondering: Who killed the Webmaster?"

EggsAndSausage writes "Microsoft has granted, in a roundabout way, that Vista has 'high impact issues.' It has put out an email call for technical users to participate in testing Service Pack 1, due out later this year, which will address 'regressions from Windows Vista and Windows XP, security, deployment blockers and other high impact issues.' It's hard to know whether to be reassured that Service Pack 1 is coming in the second half of 2007, and thus that there is a timeframe for considering deployment of Vista within businesses, or to be alarmed that Microsoft is unleashing an OS on the world with 'high impact issues' still remaining." In other news, one blogger believes that Vista is the first Microsoft OS since Windows 3.1 to have regressed in usability from its predecessor (he kindly forgives and dismisses Windows ME). And there's a battle raging over the top 10 reasons to get Vista or not to get Vista.
