June 24, 2013 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?

Bad bug: The bacterium Clostridium difficile kills 14,000 people in the United States each year.
June 18, 2013 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.

To fight antibiotic-resistant staph germs like these, a study suggests disinfecting the skin of all intensive care patients.
May 29, 2013 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.
Fungi (cyan) surround a human hair within the skin. A study in the journal Nature shows the population of fungi on human skin is more diverse that previously thought.

May 22, 2013 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.

May 16, 2013 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.

May 15, 2013 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.

Sucking may be one of the most beneficial ways to clean a baby's dirty pacifier, a study found
May 6, 2013 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.

April 24, 2013 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.

April 10, 2013 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.

April 4, 2013 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.

April 2, 2013 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.

The anthrax vaccine has been given to more than 1 million adults in the military. But no one knows how well it would work in children.
March 19, 2013 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."
