When you eat a cup of yogurt, billions of bacteria make their way to your gut. Some researchers believe that these "probiotics" can be good for you, alleviating everything from bowel disease to allergies. Now, a team of researchers has shown that, at least in mice, supplementing food with a helping of "good" bacteria can cause profound metabolic changes, including some that may be linked to weight loss.

This idea foretells an exciting and potentially revolutionary future in which microbial interventions can correct metabolic abnormalities.
