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."

astroengine writes "Building on previous studies by the Hubble Space Telescope, new analysis of gravitational lensing data has revealed the most detailed map of the distribution of dark matter yet. The distribution appears as a beautiful ghost-like or ethereal haze and could have serious ramifications on our understanding as to how galaxy clusters form and evolve."

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."

MMBK writes "It's the ultimate salvagepunk experiment, building a telegraph out of things found in the woods. From the article: 'During the summer of 2009, artist Jamie O’Shea of the organization Substitute Materials set out to test whether or not electronic communication could have been built at any time in history with the proper knowledge, and with only tools and materials found in the wilderness of New Jersey.'"

Not that it will change anything, but researchers at Bristol University say that your dog might be a gloom-monger. In addition to the downer dogs, the study also found a few that seemed happy no matter how uncaring the world around them was. "We know that people's emotional states affect their judgments and that happy people are more likely to judge an ambiguous situation positively. What our study has shown is that this applies similarly to dogs," said professor Mike Mendl, an author of the study and head of animal welfare and behavior at Bristol University.

Pope Benedict XVI has warned that people are in danger of being unable to discern reality from fiction because of new technologies, and not old books. "New technologies and the progress they bring can make it impossible to distinguish truth from illusion and can lead to confusion between reality and virtual reality. The image can also become independent from reality, it can give birth to a virtual world, with various consequences -- above all the risk of indifference towards real life," he said.

An anonymous reader writes "The Advanced Concepts Team of the European Space Agency is celebrating World Space Week (4-10 October 2010) with the release of 'The Space Game,' an online game for interplanetary trajectory design. The Space Game is an online crowdsourcing experiment where you are given the role of a mission designer to seek the best path to travel through space. The interactive game, coded in HTML5, challenges the players to devise fuel-efficient trajectories to various bodies of the Solar System via a user-friendly interface. The aim of the experiment is get people from all ages and backgrounds to come up with better strategies that can help improve the effectiveness of the current computer algorithms. As part of the events organized worldwide for Space Week, the first problem of the game is to reach Jupiter with the lowest amount of propellant. The best scores by 10 October will be displayed on the Advanced Concepts Team website and the three best designs will also receive some ESA prizes."

angry tapir writes "Nintendo's 3DS, the first portable game device with 3D graphic technology, will go on sale in Japan on Feb. 26 next year. The 3DS will cost ¥25,000 (US$298), Satoru Iwata, Nintendo's president, told a packed news conference in Chiba, Japan. It will launch in Europe, Australia and the US in March." Nintendo also detailed a number of games that will launch at or near the same time, and they said the online shop would get some improvements

Gksksla writes "Scientists in Australia and Hong Kong have conducted a comprehensive study to discover how different body measurements correspond with ratings of female attractiveness. The study, published in the Journal of Evolutionary Biology, found that across cultural divides young, tall and long armed women were considered the most attractive."

Born 14 weeks early, Lexi Lacey owes her life to some MacGyver inspired doctors and a sandwich bag. Lexi was so small at birth that even the tiniest insulating jacket was too big, but she fit into a plastic sandwich bag nicely. ''The doctors told us they had never known a baby born as prematurely as Lexi survive. She was so tiny the only thing they had to keep her body temperature warm was a sandwich bag from the hospital canteen — it's incredible to think that saved her life," says her mom.

tetrahedrassface writes "When the Sociolinguistics Symposium met earlier this month swearing scholar Timothy Jay revealed that an increase in child swearing is directly related to an increase in adult swearing. It seems that vulgarity is increasing as pop culture continues to popularize vulgarities. The blame lies with media, public figures, politicians, but mostly ourselves. From the article: 'Children as young as two are now dropping f-bombs, with researchers reporting that more kids are using profanity — and at earlier ages — than has been recorded in at least three decades.'"
