Stresses determine the shape of life

Patterns are everywhere in nature, from the leopard's spots to the nautilus's spiral shell, but scientists struggle to understand the mechanisms that produce them. Researchers in the US now believe that physics of microtubules is an important piece in the puzzle.

Jim Valles and Jay Tang at Brown University, have worked out that physics is behind the patterns formed by microtubules – proteins that play a fundamental role in cell division and organism development. "What's exciting is that this finding may provide insight into how the shapes that make up the human body are created".
