How about a pair of coronal mass ejections

A new forecast for the United States suggests designer burberry outlet that 42 percent adult Americans could be obese and 11 percent severely obese by the year 2030. The estimates are part of two Institute of Medicine (IOM) reports issued Monday and Tuesday at the U.S. Centers for Disease Control and Prevention’s (CDC’s) Weight of the Nation conference in Washington. The scientists who conducted the research say a strategy requiring action across all levels of society is needed to reverse the problem of obesity. IOM figures indicate that 34 percent of adults in the U.S. currently are obese, and six percent are severely obese. Severe obesity generally is defined Burberry handbags outlet, cheap burberry bags on sale, 60% off as being about 45 kilograms overweight. One IOM study concludes the source of America’s overweight epidemic is an environment that promotes obesity, rather than a lack of individual willpower. The co-authors made a long list of recommendations, including focusing heavily on schools where children spend most of their days, cutting farm subsidies that prohibit U.S. farmers from planting fruits and vegetables, and taxing sugar-sweetened beverages such as carbonated soda. The IOM report also urges that healthy food and drink choices be more widely available to allow Americans to make better choices, not only at restaurants, but while louis vuitton sunglasses at school, shopping or at entertainment and sports venues. A "monster sunspot" more than 60,000 miles wide could send some powerful solar flares toward Earth on Wednesday, NASA says. The sunspot -- actually a group of four spots, each larger than Earth, and smaller spots -- emerged over the weekend and was spotted by the orbiting Solar Dynamics Observatory and amateur astronomers, Spaceweather.com reported (via Space.com). It tossed off a moderately strong M-class flare today, and is expected to follow up with even stronger flares, possibly even X class. Sunspot AR 1476 is so big that a photographer in the Philippines captured it at sunset, without a solar telescope. But Spaceweather offers potential sungazers this crucial warning: Even when the sun is dimmed by clouds and haze, louis vuitton set looking into the glare can damage your eyes. Looking through unfiltered optics is even worse. If you chose to photograph the low sun, use the camera's LCD screen for viewfinding. Sunspots don't excite you? How about a pair of coronal mass ejections, or a dark, coronal hole that has opened in the sun's atmosphere and is hurling solar winds toward us? Good chance of strong geomagnetic activity, including auroras. Want to know the space weather now? NOAA has it. The latest sun show comes three weeks after the Louis vuitton shoes discount for women sale outlet spectacular eruption captured by the solar orbiter.
