Mathematicians have discovered a new class of mathematical shapes called soft cells that can be used to describe patterns in living organisms. These shapes, which contain as few sharp corners as possible, are able to fit together snugly and are found in various biological processes and structures, such as muscle cells and nautilus shells. Soft cells have been found to be widespread in the real world, including in architecture and biological growth. The discovery of these shapes could improve our understanding of the geometry and material properties of biological systems. [Extracted from the article]
