Subject: 16'th update on fly longevity experiments
This is the sixteenth update of my fly experiments. The heat wave is
over so I expect life spans will be greater in the sixth run than in the
fifth run. In the fifth run all that looks interesting is activated
charcoal, sucrose and l-proline. Since activated charcoal significantly
outperformed controls in the 3'rd run, I have shortlisted this as a
"probable" life span prolonging supplement for flies.
Since the lower dosage of a supplement almost always results in a
greater life span, I am decreasing the dosages I use in the sixth run. I
am retesting l-proline as well as sage and paprika here. For the first
time I am boiling the water I use. Although flies live longer when live
yeast is added to their food, this result was obtained under highly
sterile laboratory conditions. This might not apply to my less than
completely sanitary home experiments. So I am running two control
bottles, one with added yeast from each breeding bottle to test for the
effect of live yeast. None of the supplement bottles contains live yeast
in this run. The breeding bottles were all created 20 days ago, using
boiled water and a high dose (1.04 gm) of activated charcoal added to 20
gm 4-24 medium.
