This study provides novel insight into the process by which surgical injury places the intestinal epithelium at risk for colonization by pathogenic microbes and impairment of its regenerative capacity via loss of its microbiota. We show that fecal tr

A free-falling stream of liquid quickly breaks into droplets because of surface tension, a result of the attraction between molecules. Surprisingly, a similar effect can occur in a falling stream of a granular material such as sand. Surface tension i
