    "abstract": "Commenting on the paper \"Swarming Ring Patterns in Bacterial Colonies Exposed\nto Ultraviolet Radiation\" of A.M. Delprato et al., Phys. Rev. Lett 87, 158102\n(2001) we point out that their observed ring pattern formation by colonies of\nsoil bacteria Bacillus subtilis exposed to ultra violet (UV) radiation might be\ncaused by the artificial confinement of motile bacteria evolved to live in a\n3-dimensional environment to a 2-dimensional geometry. We propose that to\ninvestigate the reaction of Bacillus subtilis to UV radiation coming from\nabove, a seminal experiment should have a 3-dimensional setup.",
