Submission + - Fossilized sea scorpion was larger than a person (www.cbc.ca)

hereisnowhy writes: A giant fossilized claw discovered in Germany belonged to an ancient sea scorpion that was much bigger than the average man, an international team of geologists and archaeologists reported Tuesday. In a report in the Royal Society's journal Biology Letters, the team said the claw indicates that sea scorpion Jaekelopterus rhenania was almost 2.5 metres long, making it the largest arthropod — an animal with a segmented body, jointed limbs and a hard exoskelton — ever found. In the report, the authors said the scorpion exceeds previous size records for arthropods by almost half a metre.

Submission + - Ethanol demand is increasing food prices worldwide

hereisnowhy writes: The rising demand for corn as a source of ethanol-blended fuel is largely to blame for increasing food costs around the world, the CBC reports. Increased prices for ethanol have already led to bigger grocery bills for the average American — an increase of $47 US compared to July 2006. In Mexico last year, corn tortillas, a crucial source of calories for 50 million poor people, doubled in price. The increase forced the government to introduce price controls. The move to ethanol-blended fuel is based in part on wide-spread belief that it produces cleaner emissions than regular gasoline. But a recent Environment Canada study found no statistical difference between the greenhouse gas emissions of regular unleaded fuel and 10 per cent ethanol-blended fuel. Environmental groups have argued that producing ethanol — whether from corn, beets, wheat or other crops — takes more energy than is derived from the product.
