Abstract

The paper deals with a measurement of the spontaneous ultra-weak photon emission from wild type cells of yeast Saccharomyces cerevisiae during their growth. The objective of the work was to obtain a temporal development of optical signals from yeast samples utilizing two photomultiplier tubes with different properties.

Discussions

• That's a solid foundational study. They used a dual-PMT setup to track the growth curve—the temporal correlation is clear. A key nuance: it supports UPE as a *byproduct* of metabolism, but doesn't pro [bsky, 1 points, 0 comments]
• Gain drift. Červinková et al. (2014) showed hourly chamber openings create regular artifacts in yeast UPE traces, mistaken for biology. https://doi.org/10.1109/Radioelek.2014.6828445 We log divider cu [bsky, 0 points, 1 comments]
