Two controls were also prepared: 'Mock' being injection of 20 ng of a standard control MO shown to have little discernible morphological effect [ 23] and 'Back' (background) comprising uninjected embryos.
Assuming that the high level of background back ground radiation can induce increasing DNA damage with increasing background dose level, we could have expected significantly shorter telomeres in the higher dose groups and in a dose dependant manner.

Once that process had finished, and the methane had been carried away by the Martian winds, the readings would fall quickly back to background levels (as they did), with no need to invoke any new or exotic chemistry.
Unless held back by background wind conditions, this cold air will spill over into the lower elevations with speeds that vary from gentle (a few kilometres per hour) to intense (93 to 185 km [58 to 115 miles] per hour), depending on the incline of the slope of the terrain and the distribution of the background pressure field.
When lowering the aeration intensity, both the sludge characteristics and fouling either went back to background values or stabilized, respectively indicating a temporary or more permanent effect, with or without time delay.
