Understanding how fat molecules are distributed and function in living organisms is key to uncovering mechanisms of aging, disease, and metabolism. Caenorhabditis elegans, a transparent roundworm, is a widely used model for studying fat storage due to its genetic similarity to humans and well-defined anatomy. However, visualizing lipids at high resolution in such a small organism has posed a major technical challenge.
