In this undated photo provided by the Gilbert family shows Dylan Gilbert, 7, of Naperville, Ill., demonstrating how he helped collect samples of bacteria from his foot during a 2012 study. Dylan’s father, microbiologist Jack Gilbert of Argonne National Laboratory, led the Home Microbiome Project that analyzed bacteria in seven homes around the country, including his own, and found the microbes that normally live in people’s bodies quickly move onto their doorknobs, countertops and floors.
