Obesity has increased dramatically in the last two decades, yet so have awareness campaigns saying appearance does not matter.    The cultural miasma is hardest on its youngest members and even kids aged 10 and 11 are concerned about their image, according to new research.  

A study of 4254 Canadian schoolchildren has shown a direct association between Body Mass Index (BMI) and satisfaction with their body shape. The research in BMC Public Health, says girls are happiest when thinnest but boys have it even worse - they are unhappy when they are too skinny or too fat.

Researchers from NIST and the University of Maryland have found what they say is a simple method of sandwiching organic molecules between silicon and metal, two materials fundamental to electronic components - perhaps overcoming one of the principal obstacles in creating switches made from individual molecules, the ultimate in miniaturization for the electronics industry.

Worried that your cold revenge plans won't come to fruition before you shake off that mortal coil?  A new Web site, www.DeathRiskRankings.com, developed by researchers and students at Carnegie Mellon University, says they can help you plan your schedule accordingly.

The tool allows users to query publicly available data from the United States and Europe, and compare mortality risks by gender, age, cause of death and geographic region. The Web site not only gives the risk of dying within the next year, but it also ranks the probable causes and allows for quick side-by-side comparison between groups.

Birds have a wide variety of vibrant plumages and have evolved various chemical and physical mechanisms to produce these beautiful colors over millions of years.  When did feathers first get iridescence, the quality of changing color depending on the angle of observation, such as the rainbow of colors seen in an oil slick?  We may be closer to an answer.   

A team of paleontologists and ornithologists has pushed the date back and discovered evidence of vivid iridescent colors in feather fossils more than 40 million years old.  It's the first evidence of a preserved color-producing nanostructure in a fossilized feather, according to their article in Biology Letters.

Kudzu has overgrown almost 10 million acres in the southeastern United States but imagine that  instead of being a nuisance it could sprout into a dietary supplement. Scientists in Alabama and Iowa are reporting the first evidence that root extracts from kudzu show promise as a dietary supplement for a high-risk condition, metabolic syndrome, that affects almost 50 million people in the United States alone.

J. Michael Wyss and colleagues note in the new study that people with metabolic syndrome have obesity, high blood pressure, high blood cholesterol, and problems with their body's ability to use insulin. Those disorders mean a high risk for heart attacks, strokes, and other diseases. Scientists have been seeking natural substances that can treat the metabolic syndrome.

If you listened to the media, a bailout of GM was good for investors.  A few months later, the stock was wiped out.   But if you paid attention to Ford Motor Company while the media ignored them, who said a bailout was a terrific idea for its competitors and then refused government money, you may have made 300% on that stock in the last 5 months.

The media being bad arbiters of quality economic advice is nothing new - they have never claimed to be otherwise because they report what they are told.  Yet the tone of advocacy the media often takes today, especially in its more popular personality-driven news shows, might lead you to believe they know what they are talking about.
