Abstract

Organisms interact with abiotic factors like temperature, light, and magnetic fields, shaping their behavior and adaptation. While Earth's magnetic field aids navigation in various species, the molecular mechanisms of magnetosensation remain unclear. This study uses Caenorhabditis elegans to investigate magnetosensation, leveraging its genetic tractability and rapid lifecycle. We identify key molecular components involved in magnetic field detection and assess their roles. Additionally, we explore the effects of reduced magnetic fields, simulating Martian conditions, on biological functions.

Beyond magnetosensation, we examine transgenerational adaptation by studying inherited pathogen avoidance behavior in C. elegans. By investigating how environmental experiences influence progeny, we aim to uncover epigenetic mechanisms of adaptation. This research enhances our understanding of sensory biology, environmental adaptation, and potential challenges for life in space.
