This rhythmicity has been observed in all the “active” LR cycles analyzed so far by the techniques of this paper. In the soil sample that was sterilized at 160º C, there was a residual (and significant) fluctuation (~50 cpm) approximately twice the radioactivity remaining after the purge from the preceding cycle. This fluctuation is marginally periodic but is attenuated by 91.5% compared to the active cycle. In the active cycle of VL2c3, a robust rhythmicity persists for as long as nine weeks. Such persistence is difficult to explain in terms of, for instance, a superoxide chemical reaction9 since such superoxides are immediately destroyed in aqueous media such as the nutrient solution employed in the LR experiments.

The periodic oscillation in LR observed here is highly correlated with a periodic oscillation in HT. A temperature-regulated change in CO2 solubility could at least partially account for the amplitude of the LR oscillation. However, the HT oscillation phase leads the LR oscillation by as much as two hours, an unusual circumstance if this were simply a chemical oscillation driven by thermal fluctuation.
