Carbon Dioxide and Lifespan in Drosophila
1 Reply
My first post to this blog began with a fascinating study by Scott Pletcher that found odor from yeast can accelerate the ageing of dietary restricted Drosophila. His group recently published another study that adds to our understanding (1), which I summarize below.
The investigators chose carbon dioxide (CO2) to study because of its known role in behavioral signaling in insects, so it was speculated that it may mediate the perception of food availability; fruit produce it as well as live yeast. Read more [...]
