Dinosaur Feather Color Discovered 219

anzha writes "Do you remember being a kid and told we'd never know what colors the dinosaurs were? For at least some, that's no longer true. Scientists working in the UK and China have closely examined the fossils of multiple theropods and actually found the colors and patterns that were present in the fossilized proto-feathers. So far, the answer is orange, black and white in banded and other patterns. The work also thoroughly thrashes the idea that fossils might not be feathers, but collagen fibers instead. If this holds up, Birds Are Dinosaurs. Period. And colorful!"

Why Most Published Research Findings Are False 259

Hugh Pickens writes "Researchers have found that the winner's curse may apply to the publication of scientific papers and that incorrect findings are more likely to end up in print than correct findings. Dr John Ioannidis bases his argument about incorrect research partly on a study of 49 papers on the effectiveness of medical interventions published in leading journals that had been cited by more than 1,000 other scientists, and his finding that, within only a few years, almost a third of the papers had been refuted by other studies. Ioannidis argues that scientific research is so difficult — the sample sizes must be big and the analysis rigorous — that most research may end up being wrong, and the 'hotter' the field, the greater the competition is, and the more likely that published research in top journals could be wrong. Another study earlier this year found that among the studies submitted to the FDA about the effectiveness of antidepressants, almost all of those with positive results were published, whereas very few of those with negative results saw print, although negative results are potentially just as informative as positive (if less exciting)."

XKCD Invited To New Yorker "Cartoon-Off" 231

UnknowingFool writes "Farley Katz, who draws for New Yorker magazine, ran into xkcd.com's Randall Munroe in a grocery store. He challenged Munroe to a cartoon-off — each cartoonist to produce drawings about the Internet as envisioned by the elderly, String Theory, 1999, and one's favorite animal eating one's favorite food. In the ensuing short interview, Munroe describes XKCD as 'a webcomic about stick figures who do math, play with staple guns, mess around on the Internet, and have lots of sex. It's about three-fourths autobiographical.'"
