An anonymous reader writes "Remember, about a month ago, when a researcher claimed he had a proof that P != NP? Well, the proof hasn't held up. But blogs and news sites helped spur a massive, open, collaborative effort on the Internet to understand the paper and to see if its ideas could be extended. This article explains what happened, how the proof was supposed to work, and why it failed."

astroengine writes "Could we detect a huge volcanic eruption on an exoplanet 30 light-years from Earth? Possibly, say scientists from the Harvard-Smithsonian Center for Astrophysics. What's more, there may be an opportunity for us to spot the ashy pollution ejected into the exoplanetary atmosphere when NASA's James Webb Space Telescope is launched in 2014. According to Discovery News, this would be a huge discovery if an Earth-like world was found to have active volcanoes: 'A geologically active terrestrial planet may be more suitable for life. It recycles crust, unleashes greenhouse gasses, opens new environmental niches, and generally provides a dynamic environment for advantageous life forms.'" According to a related story at the BBC, we should soon be able to detect the presence of oceans on distant worlds as well. The JWST will be able to resolve the reflection of light off an ocean's surface from 20-30 light-years away.

epee1221 writes "Markus Persson, a.k.a. Notch, the developer of Minecraft, posted on his development blog today that PayPal limited his account with unspecified cause on August 25th. Since then, payments for the alpha version of Minecraft have continued accumulating while Notch has been unable to withdraw them, and the account now contains over €600,000. PayPal recently told him it may take up to two more weeks for things to get sorted out and that if they conclude that there is funny business involved, they will keep the money." This unfortunate news followed an announcement a few days ago that he and a friend would be starting a studio of their own to continue development on Minecraft and start working on a new project.

An anonymous reader writes "Stem cell tourism is a booming and troubling industry, in which clinics in places like Mexico, China, and India offer rich tourists experimental stem-cell-based treatments, none of which have been approved by the FDA here in the US. (Check out some of these creepy sites that offer treatments for everything from autism to MS, and even the 'very common ailment called aging.') But in one positive development, Costa Rica just shut down its top stem cell clinic. Said the country's health minister, 'This isn't allowed in any serious country in the world.'"

RickJWagner writes "CodeIgniter is a multi-purpose, open source PHP web application framework that can dramatically reduce the amount of coding required in developing a full-featured website. This book promises to introduce the reader to the most productive APIs and demonstrate their usage with minimal code snippets. In that regard, I think the book lives up to its promise." Read on for the rest of RickJWagner's review.

Jamie noted a blog that says "PostgreSQL 9.0 beta 2 just got released this week. We may see another beta before 9.0 is finally released, but it looks like PostgreSQL 9.0 will be here probably sometime this month. Robert Treat has a great slide presentation showcasing all the new features."

An anonymous reader writes "Gartner is saying it's time to plan your migration now (if you havent already done it). I for one know my company still has loads of users still on XP, citing training costs (time and money) rather than software license fees. Is my company alone in wanting to stay in the 1990s or is Windows 7 the way forward?"

Chinobi writes "Di Gao, an assistant professor at the Department of Chemical and Petroleum Engineering at the University of Pittsburgh, has developed a method of separating oil from water within just seconds using a cotton cloth coated in a chemical polymer that makes it both hydrophilic (it bonds with the hydrogen atoms in water) and oleophobic (oil-repelling), making it absolutely perfect for blocking oil and letting water pass through. Gao tested his filter successfully on Gulf Oil water and oil and has an impressive video to demonstrate the results." This is a laboratory demonstration; the technology hasn't been tested at scale.

Stoobalou writes with news that MSI is planning a big shift towards UEFI (universal extensible firmware interface) at the end of 2010, possibly spelling the beginning of the end of the BIOS as we know it. "It's the one major part of the computer that's still reminiscent of the PC's primordial, text-based beginnings, but the familiarly clunky BIOS could soon be on its deathbed, according to MSI. The motherboard maker says it's now making a big shift towards point-and-click UEFI systems, and it's all going to kick off at the end of this year. Speaking to Thinq, a spokesperson for the company in Taiwan who wished to remain anonymous said, 'MSI will start to phase in UEFI starting from the end of this year, and we expect it will be widely adopted after three years.'"

nk497 writes "It's no surprise that professional gamers aren't quite as fit as elite athletes, but they do have something in common. According to a British academic, top-level players show similar psychological attributes as top athletes, such as the ability to manage anxiety, and have reaction times on par with fighter pilots. Dr. Micklewright said, 'When I first got asked to do [the study], my initial reaction was "don't be ridiculous, gaming is nothing like sport." But the more I thought about it, the more similarities [became clear], and I became more and more convinced that it was close in many ways to sport.' While sitting in front of a screen might not have the same physical demands as running a marathon, neither do playing snooker or darts. Still, while gamers show good reflexes, their health was worse than expected, with one 20-something professional player showing the same aerobic health as a 60-year-old smoker." This story is based on a BBC radio report which you can currently hear, although that link seems to say that it won't last.

An anonymous reader writes "LimeWire owes the major record labels one point five trillion dollars, at a conservative estimate. At least, that's what an RIAA lawyer says. He also wants LimeWire shut down and its assets frozen, says Ray Beckerman's Recording Industry vs The People blog."

technology_dude found an unsurprising but amusing little story that BP is buying keywords on Google and Yahoo for things like "Oil Spill" to help spin some damage control. I guess if you can't plug your spill, the least you can do is try to clog the flow of information.

leetrout writes "SpaceX has successfully launched a two-stage rocket, the Falcon 9, into Earth orbit from Cape Canaveral Air Force Station. 'Liftoff came after hours of delay, sparked initially by launchpad telemetry problems, then by a sailboat that strayed into a restricted area of the launch range. The day's first countdown was aborted at virtually the last second, due to a problem with the engine parameters, but the launch software was adjusted and a second countdown went all the way to the end.'" Update: 06/04 20:16 GMT by S : Reader mrcaseyj points out Spaceflight Now's coverage, which includes a number of pictures from the launch.

Calopteryx writes "New Scientist reports that in 2005, researchers predicted two potential signatures of life on Titan. Now, thanks to research done with the help of the Cassini spacecraft, both have been seen, although non-biological chemical reactions could also be behind the observations. NASA's writeup has further details: 'One key finding comes from a paper online now in the journal Icarus [abstract] that shows hydrogen molecules flowing down through Titan's atmosphere and disappearing at the surface. Another paper online now in the Journal of Geophysical Research maps hydrocarbons on the Titan surface and finds a lack of acetylene. This lack of acetylene is important because that chemical would likely be the best energy source for a methane-based life on Titan, said Chris McKay, an astrobiologist at NASA Ames Research Center, Moffett Field, Calif., who proposed a set of conditions necessary for this kind of methane-based life on Titan in 2005. One interpretation of the acetylene data is that the hydrocarbon is being consumed as food. But McKay said the flow of hydrogen is even more critical because all of their proposed mechanisms involved the consumption of hydrogen.'"

saintory writes "Shuttle Atlantis landed this morning after flying its final official mission. In its 25-year service, the shuttle Atlantis has logged over 120 million miles." After a successful mission to deliver a research module to the International Space Station, the craft landed at Kennedy Space Center, and will "go through the normal flow of prelaunch preparations in order to serve as the 'launch-on-need' vehicle for Endeavour's STS-134 mission, the last scheduled flight of the Space Shuttle Program." Congratulations to the people aboard and on the ground who engineered the shuttle's successful return.
