The country's largest long-term care insurer is making it tougher for people — especially women — to buy its policy.

Genworth Financial has announced that starting this spring it will begin taking gender into account when setting premiums on new policies. The reason: Women account for two out of every three dollars spent on claims, says Thomas Topinka, a company spokesman.

It's an important question for American families and the nation as a whole: Why do so many kids weigh too much?

There are recent hints the epidemic may be abating slightly. Still, one in every three American kids is overweight or obese.

Hoping to reduce unnecessary antibiotics use, the American Academy of Pediatrics on Monday issued new guidelines for how doctors should diagnose and treat ear infections.

Prehistoric humans didn't have toothbrushes. They didn't have floss or toothpaste, and they certainly didn't have Listerine. Yet somehow, their mouths were a lot healthier than ours are today.

"Hunter-gatherers had really good teeth," says Alan Cooper, director of the Australian Centre for Ancient DNA. "[But] as soon as you get to farming populations, you see this massive change. Huge amounts of gum disease. And cavities start cropping up."

An ear, unsurprisingly, is difficult to make from scratch. Ear cartilage is uniquely flexible and strong and has been impossible for scientists to reproduce with synthetic prostheses.

If a child is born without one, doctors typically carve a replacement ear out of rib cartilage, but it lacks the wonderfully firm yet springy qualities of the original ear. And it often doesn't look so good.

So why not print one?

The most heated part of the fight between the Obama administration and religious groups over new rules that require most health plans to cover contraception actually has nothing to do with birth control. It has to do with abortion.

Specifically, do emergency contraceptives interfere with a fertilized egg and cause what some consider to be abortion?

Sticking to a diet is a challenge for many people, but starting next year, Americans may have an even bigger, financial incentive to keep their weight in check. The new health care law includes a provision that would allow employers with more than 50 employees to require overweight workers who do not exercise to pay more to cover their insurance costs.

Some employers, inspired in part by the success of shows like The Biggest Loser, are already designing weight-loss programs that use money to succeed where willpower has failed.

What if, before your children were born, you could make sure they had the genes to be taller or smarter? Would that tempt you, or would you find it unnerving?

What if that genetic engineering would save a child from a rare disease?

As advancements in science bring these ideas closer to reality, a group of experts faced off two against two in an Intelligence Squared U.S. debate on the proposition: "Prohibit Genetically Engineered Babies."

Wouldn't it be great, considering how many of us are overweight, if carrying a few extra pounds meant we'd live longer?

A recent analysis of nearly 100 published studies involving almost 3 million people found, surprisingly, that being a little overweight was associated with a lower risk of death than having a normal weight or being obese.

Many of the drugs we take aren't actually digested — they pass through our bodies, and down through the sewer pipes. Traces of those drugs end up in the bodies of fish and other wildlife. Nobody's sure what effect they have.

Now, a paper being published in Science magazine finds that drugs for anxiety drugs — even at these very low levels — can affect the behavior of fish.
