Popping Frozen Poop Pills Can Stave Off Dangerous Bacterial Infections

Fecal transplants are an effective way to combat C. difficile infections, but they're typically delivered by enema or a tube down the digestive system. Not pleasant.

Are gut bacteria the reason people who live in cold regions get fat?

Numerous animals, humans included, have adapted to living in cold climates by increasing their body size. And now, researchers have found that people living in colder regions have more obesity-related gut microbes than their warm-region counterparts.

Eventually they can become two distinct species. But new research now suggests it's not always incompatible DNA that halts interbreeding — sometimes it's incompatible… » 7/22/13 3:40pm 7/22/13 3:40pm

Rise in allergies has nothing to do with exposure to disease

Back in the late 1980s, scientists suggested that the sudden spike in allergy sufferers was the result of living in sterile homes and overzealous hygiene practices. Our immune systems, went the thinking, weren't being exposed to potentially important infections. A recent report, however, indicates that this "Hygiene… » 10/03/12 9:40am 10/03/12 9:40am

When people explode during colonoscopies

Few people, if any, look forward to colonoscopies. They're annoying to prepare for. (Liquid diet? No thank you.) They're invasive. (It's a camera. In your butt.) They're scary. (Even if it's just a routine screening, there's always a chance your doctor will find something up there that requires medical attention.) … » 9/24/12 11:13am 9/24/12 11:13am
