X-Message-Number: 27766 Date: Sun, 26 Mar 2006 19:44:15 -0800 (PST) From: Doug Skrecky <> Subject: 220'th update on fly longevity experiments This is the 220'th update of my fly longevity experiments. Average temperature was 23.6 C during this run. Estimated maximal longevity using the formula (363 - T*11.2) is 99 days. In runs #121, 123, & 126 white kidney bean at 8% and 12% concentrations extended maximum longevity. However no benefit was seen in run #171 when a white kidney bean extract called phaseolamin was tested. This run tests lower concentrations of phaseolamin, and retests white kidney bean itself. The results were equivocal this time, possibly because an older breeding bottle was used. With respect to the "control two" bottle both phaseolamin, and white kidney bean tended to acquit themselves well. However the longest living fly turned out to be one from the "control one" bottle. I conclude that if white kidney bean or its phaseolamin extract are beneficial, then this effect is likely of marginal significance.
