Biologists and mathematicians team up to explore tissue folding: An algorithm developed to study the structure of galaxies helps explain a key feature of embryonic development

Scientists have now discovered a key feature of embryonic tissue that helps explain how this process is carried out so faithfully each time. In a study of fruit flies, they found that the reproducibility of tissue folding is generated by a network of proteins that connect like a fishing net, creating many alternative pathways that tissues can use to fold the right way.
