Subject: 101'st update on fly longevity experiments
This is the 101'st update of my fly longevity experiments. Average
temperature was 23.2 C during this run. Estimated maximal longevity using
the formula (363 - T*11.2) is 103 days.
Here I retest each supplement under both ambient light, and under dark
storage conditions. In all cases the day 36, and day 41 survivals were
increased with dark storage, though maximum survival was not always
increased. Possibly the elimination of light induced immune suppression,
may have reduced virally mediated mortality. In any case I have decided to
use the dark storage condition as part of my standard protocol for
subsequent runs.
Tamarind juice increased longevity in a previous run, and this run
retested this juice, and again found increases. Wax gourd drink, like
white gourd drink previously, also increased maximum longevity. The
beneficial result with coffee and milk came as a surprise. However further
testing of coffee/milk will be needed to verify this benefit.
