Elucidation of the mechanism by which microorganisms that do not flow downstream automatically oppose the flow

 
If you write the contents roughly
This result is expected to contribute to the prediction of the habitat distribution of ciliates, which indirectly support our diet and the global environment, and the improvement of the prediction accuracy of environmental changes that accompany it.
 

Due to the shape of the cells and the nature of the cilia, the swimming microorganism ciliate Tetrahymena opposes the flow near structures in the water ... → Continue reading
