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."

jamie writes "Fantasy author Sir Terry Pratchett says he was so excited after being knighted by the Queen that he decided to make his own sword to equip himself for his new status... the author dug up 81kg of ore and smelted it in the grounds of his house, using a makeshift kiln built from clay and hay and fueled with damp sheep manure."

disco_tracy writes "A California inventor has filed a patent for a coffin that screws into the ground vertically. The reason? It greatly reduces excavation labor and burial costs, decreases land use, and opens up more space for burials in unused areas of a cemetery. Writer Clark Boyd also lists 5 other unconventional burial options, including lye, ecopods, GPS devices that track bodies buried without headstones, cryogenics and — my favorite — getting buried in the sky."

jerryjamesstone writes "Everybody is into rail these days; it is the greenest way to get around next to a bike. Leonid Mulyanchik has been into it for years since before the Berlin Wall fell, since before the first Macintosh, building his own private underground Metro railway system. English-Russia says that he has been doing it with his pension, that it is all legal and approved and that he is still at it. Gizmodo calls it 'Partly the traditional, inspiring, one man against all odds type of persistence, but more the obsessive, borderline insane persistence.'" Update: 06/02 07:33 GMT by T : And if you're the type to visit Burning Man, you can actually ride a home-made monorail this summer, too.

Hugh Pickens writes "The NY Times reports that state legislators in Wisconsin raced against the clock to pass a bill designating Lactococcus lactis as Wisconsin's official state microbe. 'The first time I heard the idea, I thought, I've got more important things to do than spending my time honoring a microbe,' says Gary Hebl, a Democratic state representative who proposed the bill which, he says, would make Wisconsin the first state in the nation to grant such a designation, 'but this microbe is really a very hard worker,' added Hebl, referring to the bacterium supported by the Department of Bacteriology at UW — Madison used to make cheddar, Colby, and Monterey Jack cheese. The proposal faced only one detractor in committee ('the opponent was clearly lactose-intolerant,' says Hebl), and there was no sign of a last-minute campaign from other bacteria, so by evening, the Assembly had approved the measure, 56 to 41. In case there were any doubts about Wisconsin's priorities, a separate bill also awaits consideration in Madison, declaring cheese Wisconsin's state snack."

SlideRuleGuy writes "In a bold and bizarre attempt to destroy evidence seized during a federal raid, a New York City man grabbed a flash drive and swallowed the data storage device while in the custody of Secret Service agents. Records show Florin Necula ingested the Kingston flash drive shortly after his January 21 arrest outside a bank in Queens. A Kingston executive said it was unclear if stomach acid could damage one of their drives. 'As you might imagine, we have no actual experience with someone swallowing a USB.' I imagine that would be rather painful. But did he follow his mother's advice and chew thoroughly, first? Apparently not, as the drive was surgically recovered."

astroengine writes "After 4 years of processing the highest resolution photographs the Hubble Space Telescope could muster, we now have the highest resolution view of Pluto's surface ever produced. Most excitingly, these new observations show an active world with seasonal changes altering the dwarf planet's surface. It turns out that this far-flung world has more in common with Earth than we would have ever imagined."

cremeglace writes "Have you ever noticed that the first cowboy to draw his gun in a Hollywood Western is invariably the one to get shot? Nobel-winning physicist Niels Bohr did, once arranging mock duels to test the validity of this cinematic curiosity. Researchers have now confirmed that people indeed move faster if they are reacting, rather than acting first."

alphadogg writes "The US IT market will grow by 6.6% as high-tech spending rebounds in 2010, according to Forrester Research's latest estimates. The research firm based its projections on data reported for 2009, though its fourth quarter numbers are incomplete. Forrester says hints of a recovery surfaced in the third quarter, and now the company expects the global IT market to grow by 8.1% in 2010. Forrester's US and Global IT Market Outlook: Q4 2009 reads: 'The tech downturn of 2008 and 2009 is unofficially over, while the Q3 2009 data for the US and the global market showed continued declines in tech purchases (as we expected). We predict that the Q4 2009 data will show a small increase in buying activity, or at worst, just a small decline.'"

grrlscientist writes "While living and working as a marine biologist in Maldives, Charles Anderson noticed sudden explosions of dragonflies at certain times of year. He explains how he carefully tracked the path of a plain, little dragonfly called the Globe Skimmer, Pantala flavescens, only to discover that it had the longest migratory journey of any insect in the world."

Astronomers from UC Berkeley have identified 33 pairs of waltzing black holes, closing the gap somewhat between the observed population of super-massive black hole pairs and what had been predicted by theory. "Astronomical observations have shown that 1) nearly every galaxy has a central super-massive black hole (with a mass of a million to a billion times the mass of the Sun), and 2) galaxies commonly collide and merge to form new, more massive galaxies. As a consequence of these two observations, a merger between two galaxies should bring two super-massive black holes to the new, more massive galaxy formed from the merger. The two black holes gradually in-spiral toward the center of this galaxy, engaging in a gravitational tug-of-war with the surrounding stars. The result is a black hole dance, choreographed by Newton himself. Such a dance is expected to occur in our own Milky Way Galaxy in about 3 billion years, when it collides with the Andromeda Galaxy."

Researchers from the School of Medicine at the University of California have shown that the more germs a child is exposed to, the better their immune system in later life. Their study found that keeping a child's skin too clean impaired the skin's ability to heal itself. From the article: "'These germs are actually good for us,' said Professor Richard Gallo, who led the research. Common bacterial species, known as staphylococci, which can cause inflammation when under the skin, are 'good bacteria' when on the surface, where they can reduce inflammation."
