Abstract
Owing to the limited printing space in JCBFM and our current backlog of papers waiting to go to print, new word limits and figure/table limits have been instituted for our journal. You will find these in the Guide to Authors, which can be located on the submission website and on the www.nature.com/jcbfm website. Although these new limits were instituted in August, we will not be returning any manuscripts that do not meet the new limits until 1 October 2007. Please review the new limits before submitting a new manuscript to JCBFM.
