    A flagellate-to-amoeboid switch in the closest living relatives of animals

    Thibaut Brunet et al.
    The closest living relatives of animals, the choanoflagellates, switch from a flagellate to an amoeboid phenotype under confinement.

    Hydrodynamics of sponge pumps and evolution of the sponge body plan

    Seyed Saeed Asadzadeh et al.
    The architecture of flagellated chambers in sponge pumps is linked to that of body plan, supporting the current view that the sponge aquiferous system evolved from an open-type filtration system.

    Sonic hedgehog signaling directs patterned cell remodeling during cranial neural tube closure

    Eric R Brooks et al.
    Closure of the cranial neural tube, which is essential for mammalian development, is driven by spatially and temporally patterned cell remodeling events that require positionally regulated Sonic hedgehog signaling.

    Topological constraints in early multicellularity favor reproductive division of labor

    David Yanni et al.
    Mathematical modeling shows that reproductive specialization is strongly favored in sparse networks of cellular interactions that reflect the morphology of early multicellular organisms, even when benefits of specialization are saturating.

    Breakage of the oligomeric CaMKII hub by the regulatory segment of the kinase

    Deepti Karandur et al.
    Activation and autophosphorylation of CaMKII releases the regulatory segment, which can then bind to and destabilize the hub assembly by trapping large fluctuations in the hub architecture.

    The genetic factors of bilaterian evolution

    Peter Heger et al.
    Advanced orthology clustering of bilaterian and non-bilaterian sequences identifies 157 bilaterian-specific genes which are linked to key morphological features of this animal group.

    Genome expansion in early eukaryotes drove the transition from lateral gene transfer to meiotic sex

    Marco Colnaghi et al.
    Lateral gene transfer is unable to resist mutation accumulation in large genomes, leading to selective pressure for the origin of meiotic sex in the first eukaryotes.

    The Sec1/Munc18 protein Vps45 holds the Qa-SNARE Tlg2 in an open conformation

    Travis J Eisemann et al.
    Whereas in a paradigmatic structure an SM protein chaperone clamps its client SNARE shut, a second structure demonstrates that an SM protein can also hold its SNARE open to promote assembly.

    Skd3 (human ClpB) is a potent mitochondrial protein disaggregase that is inactivated by 3-methylglutaconic aciduria-linked mutations

    Ryan R Cupo, James Shorter
    Skd3 (human ClpB) is a potent ATP-dependent mitochondrial protein disaggregase that is activated by the rhomboid protease, PARL, and inactivated by MGCA7-linked mutations.

    Genome editing enables reverse genetics of multicellular development in the choanoflagellate Salpingoeca rosetta

    David S Booth, Nicole King
    Genome editing in the choanoflagellate Salpingoeca rosetta opens newfound possibilities to functionally probe choanoflagellate genes that may illuminate the origin of their closest relatives, the animals.
