a Density maps of swarming in the presence (upper panel) and in the absence of urea (lower panel) for 90 s (scale bar = 2 mm) and (b) the corresponding X axis projection with time (0, 5, 10, 30, 60, and 90 s). c Particle image velocity (PIV) analysis of swarm according to the urea concentration for 2 s (45 s−47 s). The density maps and PIV images are representative of 3 independent experiments. d Expanding area according to the urea concentration for 90 s. Data are presented as mean values and error bars represent the S.D. (n = 3 per group, biological replicates). e The gray scale of ROI region indicated in supplementary Fig. 4c at 30 s. The gray scale of ROI region is representative of 3 independent experiments. Black dot lines indicate the width of ring patten in swarm. Source data are provided as a Source Data file.
