    Output variability across animals and levels in a motor system

    Angela Wenning et al.
    Population output variability in a motor control system varies across levels (CPG, motor neurons, muscles) and can be ascribed to life history differences among animals and in some cases to differences between bilaterally homologous elements.

    Hidden synaptic differences in a neural circuit underlie differential behavioral susceptibility to a neural injury

    Akira Sakurai et al.
    Animal-to-animal variability in neural circuit elements is often hidden under normal conditions, but becomes functionally relevant when the system is challenged by injury.

    The Natural History of Model Organisms: Advancing biology through a deeper understanding of zebrafish ecology and evolution

    David M Parichy
    The zebrafish is a premier model organism for biomedical research, with a rich array of tools and genomic resources, and combining these with a fuller appreciation of wild zebrafish ecology could greatly extend its utility in biological research.

    Science Forum: Unit of analysis issues in laboratory-based research

    Nick R Parsons et al.
    A simulation study is used to demonstrate how mistakes in identifying the experimental unit and the unit of analysis can lead to incorrect analyses and inappropriate inferences when reporting research studies.
  1. Research: Theory, models and biology

    Wenying Shou et al.
    Theoretical ideas have a rich history in many areas of biology, and new theories and mathematical models have much to offer in the future.

    DNA Replication: Rethinking origin licensing

    Stephen P Bell
    Human cells that lack a subunit in their origin recognition complex are viable, which suggests the existence of alternative mechanisms to initiate DNA replication.
