Wanted: A population genetic theory of biological noise regulation

Darwin’s theory of evolution describes how mean trait values change in response to natural selection over generations. But if mean trait values are subject to natural selection, what about the amount of variation (or noise) around those means?

Genetic underpinnings of chills from art and music

Many people experience chills when listening to music, reading poetry, or viewing art. Yet not everyone feels these reactions in the same way. These differences provide a window into how our brains and bodies respond to art, revealing individual variation in emotional experiences.

Local mitochondrial physiology defined by mtDNA quality guides purifying selection

Using baker’s yeast as a model system, the authors developed a rapid approach that allowed them to track how healthy and mutant mitochondrial DNA variants are inherited when cells divide. They found that cells preferentially retain mitochondrial DNA that supports normal mitochondrial function, even under conditions where respiration is not required.
