As part of his continuing reporting on the collection of bacteria, viruses, fungi and other microbes that we all harbor, Rob Stein told his listeners about the positive benefits we can derive from our microbiome, the distinctly personal nature of our microbial ecosystems, and the privacy issues that loom now that individuals can readily and inexpensively get their microbes analyzed. One of the pieces included an imaginary bus tour through the microscopic world of the body. Judge Marc Kaufman, a science writer for The Washington Post and other publications, called Stein's stories "a tour de force, as it were…deeply reported, very important and well described. Stein uses his medium extremely well." Naomi Starobin, a project editor at WHYY radio in Philadelphia, said she found Stein's three pieces "totally engaging." Stein used "a lot of creativity and clever use of sound to tell the story," Starobin said. "He fairly presents both the promise and the reality of where the biome research will lead. His trip through the human body feels like the Magic School Bus for adults."
