Shipud writes "The National Academies Press are offering all their books for free in PDF format. These are all the publications of the National Academy of Sciences, National Academy of Engineering, Institute of Medicine, and National Research Council. Lots of great stuff there, and now for free."

flintmecha writes "A group of British schoolchildren may be the youngest scientists ever to have their work published in a peer-reviewed journal. In a new paper in Biology Letters, children from Blackawton Primary School report that buff-tailed bumblebees can learn to recognize nourishing flowers based on colors and patterns. The paper itself is well worth reading. It's written entirely in the kids' voices, complete with sound effects (part of the Methods section is subtitled, ''the puzzle'duh duh duuuhhh') and figures drawn by hand in colored pencil."

disco_tracy writes "Silkworms have been modified to produce spider silk, creating a fabric that could be used in everything from bulletproof clothing to artificial tendons." For some reason, this is far less revolting to me than the idea of spider silk being milked out of goats.

sfraggle writes "Kotaku has an interesting review of Doom (the original!) by Stephen Totilo, a gamer and FPS player who, until a few days ago, had gone through the game's 17-year history without playing it. He describes some of his first impressions, the surprises that he encountered, and how the game compares to modern FPSes. Quoting: 'Virtual shotgun armed, I was finally going to play Doom for real. A second later, I understood the allure the video game weapon has had. In Doom the shotgun feels mighty, at least partially I believe because they make first-timers like me wait for it. The creators make us sweat until we have it in hand. But once we have the shotgun, its big shots and its slow, fetishized reload are the floored-accelerator-pedal stuff of macho fantasy. The shotgun is, in all senses, instant puberty, which is to say, delicately, that to obtain it is to have the assumed added potency that a boy believes a man possesses vis a vis a world on which he'd like to have some impact. The shotgun is the punch in the face the once-scrawny boy on the beach gives the bully when he returns a muscled linebacker.'"

A few days back we discussed some of the problems caused by the demise of Intelsat's Galaxy 15, including possible degradation of GPS and its WAAS refinement. Now reader crimeandpunishment writes in with another damage scenario, one which could affect vastly more people — interference with cable TV programming across the US. "A TV communications satellite is drifting out of control thousands of miles above the Earth, threatening to wander into another satellite's orbit... Galaxy 15 continues to receive and transmit satellite signals, and they will probably interfere with the second satellite, known as AMC 11, if Galaxy 15 drifts into its orbit as expected around May 23... [A spokesman] said one option would be using AMC 11's propulsion system to shift that satellite about 60 miles (100 kilometers) away to an orbit that's still within its carefully prescribed 'orbital box' but as far away as possible from Galaxy 15."

supersloshy writes "Last year, 2D Boy, the developers of the popular independent game World of Goo, had a pay-what-you-want birthday sale with curious results. For the next seven days, Wolfire Games is attempting the same kind of sale, but with some new twists. Wolfire Games' Humble Indie Bundle contains five independent games (World of Goo, Aquaria, Gish, Lugaru HD, and Penumbra) with no DRM and they are all cross-platform. In addition to directly supporting the developers of these five games, part of the money also goes to the Electronic Frontier Foundation and the Child's Play Charity. No matter how much you spend, you also get to choose who your money goes to (charity only, developers only, evenly, or custom)."
