audiovideodisco writes "Even among octopuses, the Argonaut must be one of the coolest. It gets its nickname — 'paper nautilus' — from the fragile shell the female assembles around herself after mating with the tiny male (whose tentacle/penis breaks off and remains in the female). For millennia, people have wondered what the shell was for; Aristotle thought the octopus used it as a boat and its tentacles as oars and sails. Now scientists who managed to study Argonauts in the wild confirm a different hypothesis: that the octopus sucks air into its shell and uses it for ballast as it weaves its way through the ocean like a tiny submarine. The researchers' beautiful video and photographs show just how the Argonaut pulls off this trick. The regular (non-paper) nautilus also uses its shell for ballast, but the distant relationship between it and all octopuses suggests this is a case of convergent evolution."

According to the New York Times, CougarLife.com had been paying Google $100,000 a month since October. The Mountain View company has now cancelled the contract, saying that the dating site is 'nonfamily safe.'"
Julie188 writes "Researchers from the University of Virginia have found that current algae biofuel production methods consume more energy, have higher greenhouse gas emissions and use more water than other biofuel sources, such as switchgrass, canola and corn. The researchers suggest these problems can be overcome by situating algae production ponds behind wastewater treatment facilities to capture phosphorous and nitrogen — essential algae nutrients that otherwise need to come from petroleum."
An anonymous reader sends in a nostalgic piece about Dungeons & Dragons and the influence it's had on games and gamers for the past 36 years. Quoting: "Maybe there was something in the air during the early '70s. Maybe it was historically inevitable. But it seems way more than convenient coincidence that Gygax and Arneson got their first packet of rules for D&D out the door in 1974, the same year Nolan Bushnell managed to cobble together a little arcade machine called Pong. We've never had fun quite the same way since. Looking back, these two events set today's world of gaming into motion — the Romulus and Remus of modern game civilization. For the rest of forever, we would sit around and argue whether games should let us do more or tell us better stories."
garylian writes "Massively is reporting that the South Korean Supreme Court has stated that virtual currency is the equivalent of real-world money. For those of you who might not be drawing the link, the core there is that selling in-game currency for real money is essentially just an exchange of currency and perfectly legal in South Korea. This could have sweeping implications for RMT operations the world over, not to mention free-to-play games and... well, online games in general. The official story is available online from JoongAng Daily."
Arvisp writes "According to a blog post by former Google China president Kai-Fu Lee, Apple plans to produce nearly 10 million tablets in the still-unannounced product's first year. If Lee's blog post is to be believed, Apple plans to sell nearly twice as many tablets as it did iPhones in the product's first year."
Actually he is right. If you calculate the probability of being hit by an asteroid in one month to be 1e-20 and the probability of you being wrong is 1:50. Then the *worst* case probability of being hit by an asteroid absent any other information is ~1:50. However, in real life there is always other information. So someone may have shown with absolute certainty that the worst case probability of being hit by an asteroid is no more than 1e-6. In that case the *worst* case probability is ~0.98e-6. For the LCH the other information is that these types of collision have been happening for eons without destroying the universe. So even if the physicists are fallible the probability of destroying the universe is not that great.
