Can We Predict Which Teens Are Likely To Binge Drink? Maybe

Originally published on Wed July 2, 2014 6:07 pm

More than half of 16-year-olds in the United States have tried alcohol. While many of them learn to drink responsibly, some go on to binge on alcohol, putting themselves at risk for trouble as adults. Researchers still aren't sure why that is.

But it may be possible to predict with about 70 percent accuracy which teens will become binge drinkers, based on their genetics, brain function, personality traits and history, according to a study published Wednesday in Nature.

Medicare spending on breast cancer screening for women age 65 and older has jumped nearly 50 percent in recent years. But the rise in price was not associated with an improvement in the early detection of breast cancer.

Researchers at the Yale School of Medicine found that Medicare spending on breast cancer screening rose from $666 million in the years 2001-2002 to $962 million in the years 2008-2009.

So why the big increases in costs?

At an altitude of nearly 3 miles, the Tibetan plateau is an extreme place to live. It's cold, it's hard to grow food, and there's about 40 percent less oxygen in the air than there is at sea level.

Somehow, though, native Tibetans are adapted to it. Their bodies — and their blood in particular — work differently than those of people used to lower altitudes. The Tibetans' advantage might be thanks to an ancient inheritance.

A prestigious scientific journal Wednesday took the unusual step of retracting some high-profile research that had generated international excitement about stem cell research.

The British scientific journal Nature retracted two papers published in January by scientists at the Riken research institute in Japan and at Harvard Medical School that claimed that they could create stem cells simply by dipping skin and blood cells into acid.

Blame it on the animal crackers. A plastic jar of the treats was too enticing for a young bear in New Jersey, which got its head irretrievably wedged in the container. When people approached it to help, the 28-pound bear cub got scared — and climbed 40 feet up a tree, where it became stuck.

The incident happened in Ringwood, a small New Jersey town that's situated among forests and parkland. Workers from the state Environmental Protection Department and other local agencies got the cub safely back down and cut the jar off its head — but not before taking a photo of its plight.
