Bees Reveal Nature-Nurture Secrets 84

Posted by samzenpus from the spare-the-rod-and-spoil-the-bee dept.
NoFear writes "The nature-nurture debate is a 'giant step' closer to being resolved after scientists studying bees documented how environmental inputs can modify our genetic hardware. The researchers uncovered extensive molecular differences in the brains of worker bees and queen bees which develop along very different paths when put on different diets. The research was led by Professor Ryszard Maleszka of The Australian National University's College of Medicine, Biology and Environment, working with colleagues from the German Cancer Institute in Heidelberg, Germany and will be published next week in the online, open access journal PLoS Biology."

Going Faster Than the Wind In a Wind-Powered Cart 315

Posted by Soulskill from the any-way-the-wind-blows dept.
Shawnconna writes "Can a wind cart travel faster than the wind? A group of makers say, 'Yes!' Make: Online has published a story about the Blackbird wind cart that just set a record. This is a follow-up to an earlier story in which Charles Platt built a cart based on a viral video where a guy claimed he'd built a wind-powered vehicle that could travel downwind faster than the windspeed. Charles built one and said it didn't work. Heated debates broke out in forums, on BB, and elsewhere on the Net. In the ensuing time, a number of people have built carts and claimed success, most principally, Rick Cavallaro. He got funding from Google and JOBY to build and test a human-piloted cart. They claim success, with multiple sensor systems on board, impartial judges and experts in attendance."
