Main outcome of study (acc. to author)

The novel experimental setup chosen in this study allowed to track single cells and derived colonies thereof and thus to determine the cell cycle time and the growth rate (wich is indeed the inverse of the cell cycle time). The findings revealed that the cell cycle time for an individual cell could be shortened or prolongated by microwave exposure at around 41.782 GHz.
