...what will it take for sustainable food production to spread? It's clear that scaling up must begin with a sort of scaling down - a distributed system of many local or regional food producers as opposed to just a few massive ones. Since 1935, consolidation and industrialization have seen the number of U.S. farms decline from 6.8 million to fewer than 2 million - with the average farmer now feeding 129 Americans, compared with 19 people...
Supplements: Chemicals In part to help them survive the crowded conditions of feedlots, where infections can spread fast, conventional cattle are given antibiotics in their feed, and sometimes growth hormones, bloods and fats...
...protecting the most vulnerable first. But a new study in the Aug. 20 issue of Science suggests that in this case, the usual practice might not be the best. Rather than inoculating the people likeliest to die from H1N1/09, we may want instead to inoculate the people likeliest to spread it. After all, even the most at-risk among us can't get sick with a virus we never come in contact with. "If you can stop transmission, you can protect the people who are vulnerable," says Jan Medlock, a mathematician at Clemson University and one of the authors...
...Medlock and co-author Alison Galvani of Yale University School of Medicine studied mortality data and data of infectious contacts from the influenza pandemics of 1918 and 1957. They then built a mathematical model to determine the best distribution by age for vaccinations, in order to contain the spread of a theoretical pandemic. In their calculations, the most effective policy was to aim first for inoculating children ages 5 to 19 and adults ages 30 to 39. That's because school-age children are such a powerful nexus of flu infection: they get sick, infect one another in the close...

JetBlue has more than a million Twitter followers, more than any other brand besides Whole Foods, the NBA and Zappos, according to trackingtwitter.com. News of the deal spread across the Twitter-sphere, and about a dozen websites and blogs, like wherewejet.com, have popped up to chronicle JetBlue adventures, share itinerary ideas and find cheap places to sleep.
