Molecular Model of a Gas Vesicle (IMAGE) Delft University of Technology Caption This picture shows a detailed molecular model of a gas vesicle, a buoyancy device for microbes filled with gas. The vesicle has large pores in its wall to let gas through, but prevents water from entering due to its extremely water repellent interior. The model is available for researchers in a public data repository (zenodo.org/record/6458345).
