Lean people tend to have many more kinds of intestinal bacteria than obese people. Having too few species, regardless of your weight, appears to increase the risk for Type 2 diabetes, heart disease and cancer.

Researchers discovered what appears to be a momentary increase in electrical activity in the brain associated with consciousness. As the brain struggles to survive, it also struggles to make sense of many neurons firing in the survival attempt.

Scientists are investigating the microscopic world that lives in and on our bodies. It's becoming clear that these tiny companions play a much more complex and important role in human health than thought. But we don't yet know enough about the microbiome to use it to prevent and treat disease.

An experimental "gut check" test can tell us more about the bacteria that live inside us. By studying the way the microbial populations change over time, researchers think they may have a new tool for monitoring health.

The tiny organs created from stem cells aren't complete, but they act like regular livers when transplanted into mice, Japanese scientists say. Still, it will be years before the synthetic organs could help people with liver problems, even if further research all works out as hoped.

Donation after cardiac death involves removing organs minutes after life-support has been stopped for patients who still have at least some brain activity. Is that enough time to make sure a person won't recover?

Fecal transplants are being used more often to treat life-threatening bacterial infections. But the Food and Drug Administration worried that the still-experimental procedure put patients at risk. Now it is dropping plans to restrict transplants after doctors and patients complained.

Sarah Murnaghan, 10, has been moved to the adult waiting list for lung transplants. Murnaghan's parents are thrilled for their daughter, who's clinging to life. But a federal judge's ruling is also raising a number of concerns.

Some states have started requiring hospitals to screen their patients for the drug-resistant bacteria known as MRSA. But a study that tested different approaches to reducing infections found that screening first wasn't the most effective approach.

While studying microorganisms on humans is not new, tracking fungi is. In a census of sorts, scientists checked the skin of healthy volunteers. They found an expansive ecosystem of silent inhabitants.

Scientists in Oregon have achieved something that has eluded researchers for years. They have created stem cells that are tailored to individual patients, made from cloned embryos. That would open the door to treating many diseases, including Alzheimer's, Parkinson's, diabetes, spinal cord injuries and many others. But researchers face ethical dilemmas.

The achievement is a long-sought step toward harnessing the potential power of such cells to treat diseases. But the discovery raises ethical concerns because it brings researchers closer to cloning humans.

Instead of rinsing off the pacifier when it falls out of your baby's mouth, new research suggests that sucking it clean for them could help keep them from developing eczema and asthma. Researchers say the harmless bacteria in parents' saliva works by stimulating the babies' immune system.

When gut microbes break down certain foods like red meat and eggs, they produce a compound tied to risks for heart attack, stroke and death, a study found. The research could lead to new ways to prevent heart disease by shifting the mix of gut bacteria.

Researchers say they can measure how much pain someone is experiencing and even watch as prescription painkillers relieve it. The scanning technique could help doctors treat pain better, but the work is also fraught with questions about how the technology could interfere with the relationship between doctors and patients.

Robert G. Edwards, a British physiologist who won a Nobel Prize in 2010 for helping develop in vitro fertilization, died Wednesday. He was 87. Audie Cornish talks with Rob Stein about Edwards' work and the controversy that still surrounds the techniques he helped create.

Philosophers, poets and psychologists have long shared a fascination with dreams. Now Japanese scientists have scanned the brains of dreaming volunteers to create a lexicon of imagery that can be used to detect and decode dreams while a person sleeps.

More and more Americans are opting to live together before they get married. That's according to new federal data. And on average, cohabitations last about 22 months compared to 13 months in 1995.

About 1.2 million people die prematurely every year in China from exposure to outdoor air pollution. Smog has dogged the country as it grows at an explosive rate and burns huge quantities of fossil fuels. But there are signs that the government is beginning to take the issue more seriously.

Anthrax has long been considered one of the most likely weapons a bioterrorist might use. Some researchers think the vaccine should be tested on children to find out if it would be safe to use in an attack. But a presidential bioethics commission says that first, researchers will have to show that children would face no more than "minimal risk."
