This image shows the cell wall of an actively growing bacteria. It comes from a recently published paper describing how a team of researchers added different colored fluorescent dyes during various phases of bacterial cell growth to capture images of the parts of the cell wall that grew when exposed to the colorants. In a release describing the work, authors discussed how the method could improve the accuracy of identifying and measuring bacterial cell wall growth and advance the development of new antibiotics.
