Earlier study that showed opposite result was flawed

Cutting calories keeps yeast alive and growing long past the time they’d usually stop reproducing, a large-scale study shows.
The finding, published online the week of July 13 in the Proceedings of the National Academy of Sciences, may come as a relief to researchers who study aging. A 2014 report tracked thousands of Saccharomyces cerevisiae at once and concluded that restricting calories did not lengthen the life span of the baker’s yeast (SN Online: 7/30/14). Longevity researchers contended then that the tracking method was flawed and that restricting calories was still the most tried-and-true way to lengthen life.
