    Quantification of gene expression patterns to reveal the origins of abnormal morphogenesis

    Neus Martínez-Abadías, Roger Mateu Estivill ... James Sharpe
    Quantitative analyses associating the morphology of developing organs with dynamic gene expression patterns can reveal biological phenomena that cause malformations and malfunction but remain elusive to traditional qualitative assessments.

    Self-organization of kinetochore-fibers in human mitotic spindles

    William Conway, Robert Kiewisz ... Daniel J Needleman
    A biophysical model in which kinetochore microtubules nucleate at kinetochores and growth polward along nematic streamlines quantitatively explains kinetochore microtubule lengths, orientations, and spatially varying dynamics in metaphase human spindles.

    Preliminary paleohistological observations of the StW 573 (‘Little Foot’) skull

    Amélie Beaudet, Robert C Atwood ... Dominic Stratford
    Virtual investigation of the 3.67-million-year-old skull of 'Little Foot' using synchrotron radiation reveals histological details of Australopithecus dental and bone tissues.

    A novel cis-regulatory element drives early expression of Nkx3.2 in the gnathostome primary jaw joint

    Jake Leyhr, Laura Waldmann ... Tatjana Haitina
    Jaw joint regulatory sequence 1 (JRS1) is deeply conserved in most jawed vertebrates and displays a specific enhancer activity in the developing primary jaw joint that contributes to early nkx3.2 gene expression and jaw joint morphology.
