Traders writing (i.e., selling) put options are, therefore, the insurers. But why should their opinions affect the most (mis)quoted measure of volatility, the VIX? Many justify using options pricing because options traders are supposedly more sophisticated investors; options are considered more complex than their underlying stocks. But these are the same "sophisticated" investors who suffered enormous losses over mortgage-based securities. Can we really trust an index derived from their (mis)pricings...
...more we think in terms of are we doing everything that is within our power to affect good outcomes, and then expect responsibility from all our institutions - government, business, non-for-profit sector - then I think that's a pretty good recipe for the continued success of the American experiment. And when people see a lack of responsibility - it's part of the reason why people are furious about the bank bailouts - then they feel betrayed, particularly when they're acting responsibly in their own lives...
...HealthMap about disease flare-ups in your area. The idea is to further broaden the net of health information beyond official sources.

"We're not sure what kind of response we'll see, but the idea is to develop a two-way flow of information," says Freifield...
...findings, published in the journal Hypertension, offers a potentially new understanding of how pollutants can affect the heart. While previous studies have linked bad air - specifically, air laden with fine particulates smaller than 2.5 microns in diameter - with higher rates of heart disease and stroke, it wasn't clear exactly how the particulates did their damage. Nor was it clear which of the many components of urban air were the most hazardous - the fine particulates from burning fossil fuels that come from exhaust pipes, or the ozone gases that permeate most densely packed city streets...
...known as the circadian rhythm. Eating at inappropriate times may disturb the body's natural rhythm, setting off a string of metabolic reactions that ultimately lead to weight gain. "Because our bodies are naturally cued to eat at certain times of the day, dining at the wrong time might affect the body's ability to maintain its energy balance," he explains, meaning that our body starts to use its calories differently than it normally would. That in turn could cause fluctuations in numerous hormones, including an increase in ghrelin and a decrease in leptin - the two key hormones that govern...
