When her colleague Jie Xiao approached her to make an illustration for a journal article, Jennifer Fairman didn't know just how challenging the assignment would be. Xiao was studying E. coli bacteria. Her team had revealed the arrangement of proteins, including one called FtsZ, at the site where an E. coli bacterium divides. Though she was working for a scientific audience, Fairman says she hopes the layperson can appreciate the complexity of the microscopic world in the image. Harold Erickson, a cell biologist at Duke University who has studied FtsZ but wasn't involved in the research, called the model "quite an achievement."
