Sizing up cells: study finds possible regulator of growth
Modern biology has attained deep knowledge of how cells work, but the mechanisms by which cellular structures assemble and grow to the right size largely remain a mystery. Now, Princeton University researchers may have found the key in the nucleolus.

Proteins pull together as cells divide
Like a surgeon separating conjoined twins, cells have to be careful to get everything just right when they divide in two. Otherwise, the resulting daughter cells could be hobbled, particularly if they end up with too many or two few chromosomes.
