This is not a glow-in-the-dark gummy worm. Instead, it's the cell wall of actively growing bacteria. By adding different colored fluorescent dyes during various phases of bacterial cell growth, scientists captured images of the parts of the cell wall that grew when exposed to the colorants. This new method will enable researchers to pinpoint and measure bacterial cell wall growth with a high level of accuracy, and it may help scientists develop new and improved antibiotics. Read
