The developing vertebrate gut tube forms a reproducible looped pattern as it grows into the body cavity. Here we use developmental experiments to eliminate alternative models and show that gut looping ...

A new experimental technique has recently been developed for characterizing small dislocation loops in the electron microscope by collecting elastic diffuse scattering patterns in the vicinity of ...

For centuries, artists, biologists and mathematicians have been inspired by the recurring patterns of the plant world: the exquisite symmetry of flowers, the sweeping spirals of seeds, spines and ...
