Researchers from Rice University have found a type of amoeba that practices a sort of "primitive farming behavior." When their bacteria food become scarce, the Dictyostelium discoideum will group together and form a "fruiting body" that will disperse bacteria spores to a new area. From the article: "The behavior falls short of the kind of 'farming' that more advanced animals do; ants, for example, nurture a single fungus species that no longer exists in the wild. But the idea that an amoeba that spends much of its life as a single-celled organism could hold short of consuming a food supply before decamping is an astonishing one. More than just a snack for the journey of dispersal, the idea is that the bacteria that travel with the spores can 'seed' a new bacterial colony, and thus a food source in case the new locale should be lacking in bacteria." It's good to know that even a single celled creature is not immune to the pull of Farmville.

A Japanese aquarium is using the greenest energy possible to power the lights on its Christmas tree, an electric eel. From the article: "Each time the eel moves, two aluminum panels gather enough electricity to light up the 2-meter (6 ft 6 in) tall tree, decked out in white, in glowing intermittent flashes."

digitaldc writes "Pollution in Beijing was so bad Friday the US embassy, which has been independently monitoring air quality, ran out of conventional adjectives to describe it, at one point saying it was 'crazy bad.' The embassy later deleted the phrase, saying it was an 'incorrect' description and it would revise the language to use when the air quality index goes above 500, its highest point and a level considered hazardous for all people by US standards. The hazardous haze has forced schools to stop outdoor exercises, and health experts asked residents, especially those with respiratory problems, the elderly and children, to stay indoors."

tetrahedrassface writes "When I was very young, my dad took me on a trip to his parents' farm. He wanted to show me 'The Crater.' We walked a long way through second generation hardwoods and finally stood on the rim of a hole that has no equal in this area. As I grew up, I became more interested in The Crater, and would always tell friends about it. It is roughly 1,200 feet across and 120 feet deep, and has a strange vibe about it. When you walk up to it, you feel like something really big happened here. Either the mother of all caves is down there, or a large object smashed into this place a long, long time ago. I bought aerial photos when I was twelve and later sent images from GIS to a geologist at a local university. He pretty much laughed me out of his office, saying that it was a sinkhole. He did wish me luck, however. It may be sinkhole. Who knows? Last week I borrowed a metal detector and went poking around, and have found the strangest shrapnel pieces I have ever seen. They are composed of a metal that reacts strongly to acids. The largest piece so far reacted with tap water and dish-washing detergent. My second trip today yielded lots of strange new pieces of metal, and hopefully, one day the truth will be known. Backyard science is so much fun. And who knows; if it is indeed a cave, maybe Cerberus resides there."

Dog owners can sleep easy tonight because physicists have discovered how rapidly a wet dog should oscillate its body to dry its fur. Presumably, dogs already know. From the article: "Today we have an answer thanks to the pioneering work of Andrew Dickerson at the Georgia Institute of Technology in Atlanta and a few buddies. But more than that, their work generates an interesting new conundrum about the nature of shaken fur dynamics. Dickerson and co filmed a number of dogs shaking their fur and used the images to measure the period of oscillation of the dogs' skin. For a labrador retriever, this turns out to be 4.3 Hz."

rhettb writes "In a spectacularly creative effort to rid Guam of the brown tree snake, an invasive species which has ravaged local wildlife and angered local residents, the US Department of Agriculture is planning to 'bomb' the island's rainforests with dead frozen mice laced with acetaminophen. While it might not seem difficult to purge an island of snakes, the snake's habit of dwelling high in the rainforest canopy has so far thwarted efforts to rid the island of the pest. Eradicating the snake is a priority because it triggers more than 100 power outages a year at a cost of $1-4 million and has driven at least 6 local bird species to extinction."

An anonymous reader writes "Peter Jansen, a PhD student and member of the RepRap community, has constructed a working prototype of an inexpensive table-top laser cutter built out of old CD/DVD drives as an offshoot of his efforts to design an under $200 open-source Selective Laser Sintering (SLS) 3D printer. Where traditional laser cutters use powerful, fixed-focus beams, this new technique dynamically adjusts the focal point of the laser using a reciprocating motion similar to a reciprocating saw, allowing a far less powerful and inexpensive laser diode to be used. The technique is currently limited to cutting black materials to a depth of only a few millimeters, but should still be useful and enabling for Makers and other crafters. The end-goal is to create a hybrid inexpensive 3D printer that can be easily reconfigured for 2D laser cutting, providing powerful making tools to the desktop."

A traffic jam on the Beijing-Tibet expressway has now entered its ninth day and has grown to over 62 miles in length. This mother-of-all delays has even spawned its own micro-economy of local merchants selling water and food at inflated prices to stranded drivers. Can you imagine how infuriating it must be to see someone leave their blinker on for 9 days?

yukk writes "Mark Suppes, a web developer for Gucci, is working on his own personal fusion reactor. His work in a NYC warehouse using $35,000 of his own money and $4,000 raised on a website has made him the 38th independent researcher recognized as creating a working fusion reactor. How's that for a hobby?"

mmmscience writes "In 2009, a series of small earthquakes shook the region of L'Aquila, Italy. Seismologists investigated the tremors, but concluded that there was no direct indication of a big quake on the horizon. Less than a month later, a magnitude 6.3 earthquake killed more than 300 people. Now, the chief prosecutor of L'Aquila is looking to charge the scientists with gross negligent manslaughter for not predicting the quake."

vlangber writes "Joel Spolsky wrote a famous blog post back in 2000 called 'Things You Should Never Do, Part I,' where he wrote the following: '[T]he single worst strategic mistake that any software company can make: They decided to rewrite the code from scratch.' Here is a story about a software company that decided to rewrite their application from scratch, and their experiences from that process."

An anonymous reader tips a PC Authority review of some of the biggest technical goofs of all time. "As any computer programmer will tell you, some of the most confusing and complex issues can stem from the simplest of errors. This article looking back at history's big technical mistakes includes some interesting trivia, such as NASA's failure to convert measurements to metric, resulting in the Mars Climate Orbiter being torn apart by the Martian atmosphere. Then there is the infamous Intel Pentium floating point fiasco, which cost the company $450m in direct costs, a battering on the world's stock exchanges, and a huge black mark on its reputation. Also on the list is Iridium, the global satellite phone network that promised to make phones work anywhere on the planet, but required 77 satellites to be launched into space."

cremeglace writes "No one had seen a laser reflector that Soviet scientists had left on the moon almost 40 years ago, despite years of searching. Turns out searchers had been looking kilometers in the wrong direction. On 22 April, a team of physicists finally saw an incredibly faint flash from the reflector, which was ferried across the lunar surface by the Lunokhod 1 rover. The find comes thanks to NASA's Lunar Reconnaissance Orbiter, which last month imaged a large area where the rover was reported to have been left. Then the researchers, led by Tom Murphy of the University of California, San Diego, could search one football-field-size area at a time until they got a reflection."

TigerWolf2 writes with this excerpt from a Reuters story carried by Yahoo: "Inspired by a standard office inkjet printer, US researchers have rigged up a device that can spray skin cells directly onto burn victims, quickly protecting and healing their wounds as an alternative to skin grafts. ... Tests on mice showed the spray system, called bioprinting, could heal wounds quickly and safely, the researchers reported at the Translational Regenerative Medicine Forum."

SlashD0tter writes "Many older sound cards were shipped with line-out, microphone-in, and a line-in jacks. For years I've used such a line-in jack on an old Windows 2000 dinosaur desktop that I bought in 2000 (600 Mhz PIII) to capture the stereo audio signal from an old Technics receiver. I've used this arrangement to recover the audio from a slew of old vinyl LPs and even a few cassettes using some simple audio manipulating software from a small shop in Australia. I've noticed only recently, unfortunately, that all of the four laptops I've bought since then have omitted a line-in jack, forcing me to continue keeping this old desktop on life support. I've looked around for USB sound cards that include a line-in jack, but I haven't been too impressed by the selection. Is the line-in jack doomed to extinction, possibly due to lobbying from vested interests, or are there better thinking-outside-the-box alternatives available?"
