Along with colleagues in Oregon, Denmark, and Germany, researchers at the National Institute of Standards and Technology (NIST) took a closer look at those structures using high-energy synchrotron, revealing that they are coated with an ultra-thin layer of lipid molecules in an upright orientation, according to a recent paper published in the journal Biology Letters. The lipids might function to push away any water beneath the spatulae, allowing them to make closer contact with the surface, said physicist and co-author Tobias Weidner of Aarhus University in Denmark.
