2021-05-06 Seminar Report

In iTHEMS biology seminar on April 22, Dr. Yukinori Nishigami (Hokkaido Univ.) gave us a talk about his research results, such as modeling the swimming behavior of unicellular organisms in their environment. First, Dr. Nishigami introduced us to the diversity of unicellular eukaryotes and the fact that they have their own specific movements. Many of the participants were amazed at how a small, single-celled organism can move in complex ways using flagella and other mechanisms, and how the cells themselves can move in complex ways.
Next, he talked about the main topic: modeling the phenomenon of ciliate accumulation in a stable environment. Through careful observation and simulation, he modeled the movement and found that the movement of ciliates in such an environment is due to the simple principle of cell shape and mechanosensitivity of cilia. He presented a good example of modeling the behavior of unicellular organisms, which led to a lively discussion at the seminar. Thank you very much, Nishigami-san!
