A Brazilian tour company is in hot water, after it was revealed that it was offering tours of Rio de Janeiro slums, including photos with the local drug gang members. For $55 you get a 4 hour tour of Rocinha, the city's largest slum, including a visit to the "bocas de fumo" where traffickers sell drugs to Rio residents. If you don't want to pay for the flight to Brazil, I will drive you into the slums of Detroit for the same price. Pictures with gang members are at their discretion.

A snake gets iced in Cippi's latest adventure.

Jay writes "Firefox 3 Release Candidate 1 is out now. If yours didn't auto-update, then get it while it's hot! The release came a bit early, with Computer World noting: 'As recently as last Saturday, Mozilla's chief engineer said that although the company had locked down RC1's code, it was planning to publicly launch the build in "late May."'" My copy just downloaded — restarting after I save this story. God I hope it's better than the last beta.

Awesome action sequence from Legend of the Seeker.

modernphysics writes "The Outreach Department at Canada's Perimeter Institute for Theoretical Physics offers a wide array of online lecture playbacks examining hot topics in modern physics and beyond. Presentations include Neil Turok's 'What Banged?,' John Ellis with 'The Large Hadron Collider,' Nima Arkani-Hamed with 'Fundamental Physics in 2010,' Paul Steinhardt with 'Impossible Crystals,' Edward Witten with 'The Quest for Supersymmetry,' Seth Lloyd with 'Programming the Universe,' Anton Zeilinger with 'From Einstein to Quantum Information,' Raymond Laflamme with 'Harnessing the Quantum World,' and many other talks. The presentations feature a split-screen presentation with the guest speaker in one frame and their full-frame graphics in the other."

Alex writes "I've just uploaded the video of a piece of classical electronic music I wrote for 2 Guitar Hero controllers and software (which I created). More information about this piece, its software, and the notation involved in playing it is at alexwroten.com/works.asp and alexwroten.com/excuses.html. I just figured people might be interested in finding new ways to use their Guitar Hero mastery ... especially with the hot debate over whether or not it hinders people's musical instruction."

An anonymous reader writes "The folks over at Thought Lab have produced an extremely high-density mobile computing platform in a scooter and have been kind enough to teach us all how to make our own! The end result was a rolling system capable of long-distance war driving, GPS navigation, Skype calls on the road, serving as an Internet hot spot or a low-power pir8 radio station, as well as recording your favorite TV program so you don't miss Lost because you are lost. If that's not over the top enough, you can actually drive your scooter to, say, the Grand Canyon, plug in your electric guitar and perform live over the Web at a whim!"

Aeonite writes "As we all learned in English class, there are three points of view one can employ when writing: first person ("I learned"), second person ("You learned"), and third person ("He learned"). You are about to read a review of Second Person: Role-Playing and Story in Games and Playable Media, a book that addresses the use of second-person narration in games and related media. You are also likely to be eaten by a Grue." Read below for the rest of Michael's review.

A team of scientists at the University of Chicago will be using 22 million processor-hours to simulate the physics of exploding stars. The team will make use of the Blue Gene/P supercomputer at Argonne National Laboratory to analyze four different scenarios for type Ia supernovae. Included in the link is a video simulation of a thermonuclear flame busting its way out of a white dwarf. The processing time was made possible by the Department of Energy's INCITE program. "Burning in a white dwarf can occur as a deflagration or as a detonation. 'Imagine a pool of gasoline and throw a match on it. That kind of burning across the pool of gasoline is a deflagration,' Jordan said. 'A detonation is simply if you were to light a stick of dynamite and allow it to explode.' In the Flash Center scenario, deflagration starts off-center of the star's core. The burning creates a hot bubble of less dense ash that pops out the side due to buoyancy, like a piece of Styrofoam submerged in water."

jackieduvall writes "Medical gauze has received its first upgrade since World War I. Chemists have infused it with nanoparticles derived from kaolin clay, which somehow give it an amazing ability to stop severe bleeding. It was developed when the Navy approached a team of inorganic chemists at the University of California Santa Barbara to solve a problem with QuikClot, a zeolite-based hemostatic agent that became way too hot and caused burns when it came in contact with water or blood. While performing blood clotting tests, they realized that kaolin clay, which has been used as a control for clotting experiments since the 1950s, could also be used as a first aid product." There is a video demonstration alongside the article. It shows the gauze halting the bleeding from a pig's aorta. The blood isn't excessive, but if you're bothered by that sort of thing, you may want to skip the video.

Xandu writes "A documentary film about the BLAST balloon-borne telescope is about to premiere at the Toronto Hot Docs film festival. BLAST is a submillimeter telescope that floats on a balloon 37km in the air while observing the earliest star-formation and earliest galaxies. Its two science flights have been covered on Slashdot, the first from Kiruna, Sweden and the second from McMurdo Station, Antarctica. Virtually all the software used on BLAST is open source, and the kst display program has been discussed here as well. If you live in or near Toronto, it's showing twice, Tuesday evening and Saturday afternoon. The film contrasts the science with the human element and hardships endured while working in such exotic locations. Naturally, the movie trailer is online."
