Poking fun at a complex new system for classification of diseases is surprisingly easy and enjoyable.

Yes, there are codes your doctor will be able to use someday to submit bills for treatment of a dolphin bite (W5601XA), being struck by a dolphin (W5602XA) or "other contact" with a dolphin (W5603XA). And that's just the start.

Is there arsenic in your rice? Probably. That's the news behind a study that found surprisingly high levels of arsenic in rice-based organic toddler formula and energy bars.

One toddler formula with organic brown rice syrup as the primary ingredient had arsenic concentrations six times the federal limit of 10 parts per billion for arsenic in drinking water.

Cereal bars that contained rice products like brown rice syrup or rice flour had arsenic levels ranging from 23 to 128 parts per billion, according to researchers at Dartmouth College, who tested the products.

The man who tried to blow up a U.S. passenger plane three Christmases ago was sentenced to life in prison in a Detroit courtroom today. Umar Farouk Abdulmutallab, 25, boarded Northwest Flight 253 in Amsterdam on Dec. 25, 2009, with a massive bomb hidden in his underwear. As the plane approached Detroit, he tried to detonate the explosives. They failed to go off.

Four months ago, on the second day of his criminal trial, Abdulmutallab pleaded guilty.

Amanda Knox, the U.S. college exchange student who won an appeal to overturn her murder conviction in Italy last October, has signed a deal to write a memoir — for which she'll earn nearly $4 million, according to reports.

The plane landed at Benghazi airport, about an hour late, which seemed just about right to most people on board. Elderly women sported tattoos from their bottom lip to the tip of their chin; several men carefully removed plants that somehow survived being crushed in the overhead luggage bins.

Between lingering New Year's resolutions and impending Lenten restraint, it's the season when many people are inspired to get healthy by refusing foods they normally delight in.

Increasingly, we're seeing elimination diets that promise weight loss and a tantalizing bonus: detoxification.

"Cleansing diets" trade on this most alluring idea: By limiting our intake of food to a few super-pure items, we can free up the body to get rid of all the gunk accumulated in our cells.

Surely you've noticed that when people move from place to place and stay for a while, they tend to pick up the local accent. We could use Madonna as an example, but we're pretty sure her British accent started before she jumped the pond.

Anyway, in a new study published in the journal Animal Behaviour, two scientists found young pygmy goats, which are known as kids, do something similar.
