Over the past quarter-century there has been considerable innovation in methods for assessing the tempo and mode of evolution in paleobiological data sets. The current literature of these methods ...

Through modeling and experiments, researchers uncover a previously undescribed shape -- they call a 'scutoid' -- adopted by packed epithelial cells during embryonic development; discovery could lead ...

WRAPPING gifts in paper involves converting a 2D shape into a 3D one, which presents plenty of geometrical challenges. Mathematics can help with this, in particular by making sure that you are using ...
