You don’t often see the word beautiful in scientific articles. Yet it’s easy to see why cell biologists Niccolò Banterle and Pierre Gönczy used the word when describing a crucial cell structure called the centriole in a recent review. The scientists, of the Swiss Federal Institute of Technology Lausanne, are helping to provide a more precise view of how our cells construct this microscopic marvel.
