Would you lose weight if money were at stake?

You might want to lose weight, but the noticeable benefits seem so far off in the future that you continually procrastinate. You need a reason to get more fit right now - how about money?

A new study in the journal Archives of Internal Medicine reinforces this idea that if money were on the line, you might start on a healthier path. Web and mobile tools are cropping up to help you do this yourself - but first, a word about the study.

Low levels of Fukushima cesium found in West Coast tuna

Scientists hope to test new samples of Pacific bluefin tuna after low levels of radioactive cesium from Japan's Fukushima Daiichi nuclear accident turned up in fish caught off California in 2011, researchers reported Monday.

The bluefin spawn off Japan, and many migrate across the Pacific Ocean. Tissue samples taken from 15 bluefin caught in August, five months after the meltdowns at Fukushima Daiichi, all contained reactor byproducts cesium-134 and cesium-137 at levels that produced radiation about 3% higher than natural background sources – but well below levels considered dangerous for human consumption, the researchers say.

Cesium-137 has a radioactive half-life of about 30 years, and traces of the isotope still persist from above-ground nuclear bomb tests in the 1950s and '60s. But cesium-134, which has a half-life of only two years, "is inarguably from Fukushima Daiichi," Stanford University marine ecologist Dan Madigan told CNN.

Friendships influence kids' activity levels

While children do not make or break friendships based on physical activity, a new study suggests their social network of friends can greatly influence how much they move. The research was published in the journal Pediatrics on Monday.

"We tend to think of teenagers as being very influential amongst their peers, but now we're seeing this in a younger age group as well," said study author Sabina Gesell, assistant professor of Pediatrics at the Vanderbilt University School of Medicine.

Beware the germs in pools

It's almost the beginning of summer and you know what that means: Swim season is here. But beware. No matter how clean they may look, public pools could have nasty germs lurking in the water causing them to be more like public bathrooms.

A recent survey conducted by the Water Quality and Health Council found one in five Americans admit to using a public pool for quick relief (urinating) and seven in 10 confessed to skipping a shower before going for a swim.

According to the Centers for Disease Control and Prevention, a pre-swim shower removes sweat, cosmetics and other dirt that could mix with chlorine to create irritants in pool water.

What is Ehlers-Danlos Syndrome?

Gioia found out she had Ehlers-Danlos Syndrome at the age of 7. For years her parents had struggled to figure out why their daughter was so easily injured, but doctors couldn’t offer a diagnosis.

Ehlers-Danlos Syndrome is actually a group of genetic disorders that cause problems with a patient’s connective tissues, according to Dr. Salman Kirmani, an expert on EDS at the Mayo Clinic. Collagen and other proteins in the connective tissues act like glue to support your skin, bones, blood vessels and internal organs.

There are three main types of EDS – hypermobility, classical, and vascular – but many others exist. A specific diagnosis is determined by the degree of symptoms a patient experiences.
