Teddy Bearer of Bad News
He looks cute and cuddly, but that plush toy crushed to your child's breast might be destroying him. The stuffing inside Teddy is almost identical to materials that are used to absorb volatile chemicals in scientific laboratories—so, effectively, Teddy is a magnet for toxins. Researchers at Chatham College in Pittsburgh tested 11 plush toys and found high concentrations of the poisonous insecticide DDT, as well as PBDEs, chemicals linked to learning impairments in rodents exposed during brain development. And while recycling is usually the way to go, one toy labeled as made from recycled materials had PBDE levels about 20,000 times those of the other toys. The researchers have not yet tested best-selling toys like Li'l Miss Asbestos and Edible Lead-y Bull for toxins.

The Most Deliciously-Named Species Ever
An ancient echidna (or spiny anteater) has been given the species designation Kryoryctes cadburyi as a result of a lost bet. Yes, thats "cadburyi," as in Cadbury chocolate. Paleontologist Tom Rich led an archaeological dig at Australia's Dinosaur Cove from 1984 to 1994, where he expected to find, predictably, dinosaur bones. When a student asked what she would get if she found a mammal bone, Rich, confident they would find none, promised a cubic meter (about a ton) of chocolate to anyone who dug up a mammal specimen.
As fate would have it, a bone from an early echidna turned up, but Rich had no idea who found the bone. He did, however, know that he was on the hook for $10,000 of chocolate. Luckily, he tapped a connection at the Cadbury factory in Melbourne, and his team was invited to a showing of a cubic-meter slab of cocoa butter (normal chocolate doesn't hold together at that volume) and then invited to dig in to Cadbury chocolate bars.
Then, as a trade for services rendered, the ancient echidna was named in honor of the company whose factory made Rich's debt disappear.

Stop Global Warming: Eat Less Meat
Drive that Bugatti Veyron straight to your local vegan eatery. A University of Chicago study recently calculated that a person can better reduce emission of greenhouse gases by going vegan than by switching to a hybrid. A typical meat-and-potatoes (hold the potatoes) American causes the emission of 1.5 more tons of CO2 each year than a typical vegan. By contrast, a standard gas-guzzling car emits just over one more ton each year than a hybrid Toyota Prius. (source: the Guardian)
Gooooooooooooooooal!
European soccer is more exciting than any American sport, say the freedom-hating anti-patriots at Los Alamos National Laboratory in New Mexico. The researchers assumed that what makes a sport exciting is a favored team losing to an underdog. They found that English Premier League soccer has a higher rate of upsets than any of the major American leagues in football, baseball, hockey or basketball. Of the American sports, the researchers found baseball to be the most exciting and football to be the most predictable. The scientists note that frequent upsets mean evenly matched teams and therefore more competitive leagues. When the best teams increase their strength at the expense of weaker teams, upsets are less likely to occur. Nobody loves a dynasty...except Yankee fans.
