Quantum noise may limit the mechanosensory sensitivity of cilia in the left-right organizer of the vertebrate bodyplan

TL;DR

This paper explores the hypothesis that quantum noise, rather than classical thermal noise, could limit the sensitivity of cilia in vertebrate embryonic development, suggesting quantum mechanics may play a role in biological mechanosensing.

Contribution

It proposes that quantum noise may influence cilia-based mechanosensing in the embryonic left-right organizer, introducing a novel perspective on quantum biology in development.

Findings

Quantum noise may limit cilia sensitivity.

Active cooling could mitigate quantum noise effects.

Quantum biology might be relevant in embryonic mechanosensing.

Abstract

Could nature be harnessing quantum mechanics in cilia to optimize the sensitivity of the mechanism of left-right symmetry breaking during development in vertebrates? I evaluate whether mechanosensing -- i.e., the detection of a left-right asymmetric signal through mechanical stimulation of sensory cilia, as opposed to biochemical signalling -- might be functioning in the embryonic left-right organizer of the vertebrate bodyplan through quantum mechanics. I conclude that there is a possible role for quantum biology in mechanosensing in cilia. The system may not be limited by classical thermal noise, but instead by quantum noise, with an amplification process providing active cooling.
