Federal officials warned Tuesday that an especially dangerous group of superbugs has become a significant health problem in hospitals throughout the United States.

These germs, known as carbapenem-resistant Enterobacteriaceae, or CRE, have become much more common in the last decade, according to the Centers for Disease Control and Prevention. And the risk they pose to health is becoming evident.

Scientists believe a little girl born with HIV has been cured of the infection.

She's the first child and only the second person in the world known to have been cured since the virus touched off a global pandemic nearly 32 years ago.

Doctors aren't releasing the child's name, but we know she was born in Mississippi and is now 2 1/2 years old — and healthy. Scientists presented details of the case Sunday at a scientific conference in Atlanta.

Robert Lustig wants to convince the world that sugar is making us very sick. And lately he's turned to an unconventional field – econometrics – to do it.

Lustig rounded up statisticians and epidemiologists to look at the relationship between food and diabetes risk. The paper, published this week in the journal PLoS One, found that the more sugar on the market in 175 countries, the higher the country's diabetes rate.

When NPR, the Robert Wood Johnson Foundation and the Harvard School of Public Health asked parents and caregivers in our new poll whether getting a good night's sleep is important, families overwhelmingly told us that sleep is a high priority.

But almost all said that it's difficult to pull off. And studies suggest this is especially true for teenagers.

Most cases of sexual assault or harassment on school campuses don't attract national attention.

There's great enthusiasm among some global health leaders about a bold – some say radical — strategy to prevent pregnant women from transmitting HIV to their newborns.

But skeptics worry that the approach, dubbed Option B+, will pit pregnant women with HIV against others infected with the virus, diverting resources from the broader struggle against the pandemic.

After a devastating earthquake hit Haiti in 2010, governments and foundations from around the world pledged more than $9 billion to help get the country back on its feet.

Only a fraction of the money ever made it. And Haiti's President Michel Martelly says the funds aren't "showing results."

Researchers say more young American women are being diagnosed with advanced breast cancer.

It's a newly recognized trend. The numbers are small, but it's been going on for a generation. And the trend has accelerated in recent years.

Most families know that their kids need to exercise. In a poll that NPR recently conducted with the Robert Wood Johnson Foundation and the Harvard School of Public Health, practically all of the parents surveyed said it's important for their kids to exercise. But about one-third of them said that can be difficult.

Dealing Coke to customers called "heavy users." Selling to teens in an attempt to hook them for life. Scientifically tweaking ratios of salt, sugar and fat to optimize consumer bliss.

In his new book, Salt Sugar Fat: How the Food Giants Hooked Us, Pulitzer Prize-winning journalist Michael Moss goes inside the world of processed and packaged foods.

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.

Ancient Chompers Were Healthier Than Ours

Feb 24, 2013

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.
