The tiny air-filled bubbles some photosynthetic microorganisms use as flotation devices could be engineered into powerful biomedical applications. Rice University bioengineers created a road map of the protein-protein interactions that…
Different materials allow substances to pass through their narrow channels based on the size of the substance compared to the channel opening and whether the material is rigid or flexible.…
