Professor Wu Yilin of Department of Physics discovered that bacteria, which seem to randomly move, in fact go in a similar speed and oscillate in predictable elliptical spheres when individual movements of each cell are filtered out from the defocusing images. It is revealed by physical tracers and image-processing techniques that the weak individual interactions of bacteria will drive each other to form a similar group orbit, which lead to a loose pattern of collective oscillation.
Apart from sharing the findings earlier in Nature, Professor Wu continues to search for the clues explaining the formation and structure of bacterial biofilms, which could help suggest ways to affect antibiotic resistance, treat cancer-tumor cells dispersion and migration inside body, and more importantly, provide insights to the research in ecology and human health.
