Breaking Wind: Flatology and How Scientists Study Farts California Academy of Sciences - California Academy of Sciences Called "America's funniest science writer" by the Washington Post, author Mary Roach takes us down the hatch on an unforgettable tour of our insides. The alimentary canal is classic Roach terrain: the questions inspired by our insides are as taboo, in their own way, as the cadavers in Stiff, and every bit as surreal as the universe of zero gravity explored in Packing for Mars. Why is crunchy food so appealing? Why is it so hard to find names for flavors and smells? Why doesn't the stomach digest itself? How much can you eat before your stomach bursts? Can constipation kill you? Did it kill Elvis? We meet scientists who tackle the questions no one else thinks —or has the courage —to ask. And we go on location to a pet food taste-test lab, a bacteria transplant, and into a live stomach to observe the fate of a meal. Like all of Roach's books, GULP! is as much abou

What does this disaster mean long-term for the nuclear industry? Mike Atkinson: It gives us an opportunity to reconsider very carefully our options in nuclear safety, alternative energy sources. Does the radiation from an event of this size as far as safety goes eventually spread all over the world? There is always a possibility that a nuclear reaction can spread radioactivity over large distances. In this particular situation there is less energy in the reactor building so that high level deposition of spread is extremely unlikely." So we’re talking about weather and wind direction I suppose? The wind is a major factor, the wind drives the radioactivity in different directions, depe
