    Ancient mechanisms for the evolution of the bicoid homeodomain's function in fly development

    Qinwen Liu et al.
    Transgenic animals carrying reconstructed ancestral alleles reveal how two ancient mutations allowed a regulatory protein to evolve a controlling role in embryonic development in flies.

    SIR-2.1 integrates metabolic homeostasis with the reproductive neuromuscular excitability in early aging male Caenorhabditis elegans

    Xiaoyan Guo, L René García
    A protein called SIR-2.1 helps to protect worms from the effects of aging by regulating metabolic processes that would otherwise generate damaging reactive oxygen species.

    The dynamic nature of the human origin recognition complex revealed through five cryoEM structures

    Matt J Jaremko et al.
    The origin recognition complex is a dynamic complex that assumes various conformational states that likely correspond to different steps in replication initiation.

    Probabilistic, spinally-gated control of bladder pressure and autonomous micturition by Barrington’s nucleus CRH neurons

    Hiroki Ito et al.
    Ponto-spinal CRH neurons in Barrington’s nucleus are a core component of an inferential circuit that regulates autonomous micturition and generates voids when the bladder is full.

    Lamellar projections in the endolymphatic sac act as a relief valve to regulate inner ear pressure

    Ian A Swinburne et al.
    The pressure of fluid in the inner ear is controlled by opening of cellular valves in the endolymphatic sac to allow for regulated transepithelial fluid flow.

    Mononuclear diploid cardiomyocytes support neonatal mouse heart regeneration in response to paracrine IGF2 signaling

    Hua Shen et al.
    Neonatal mouse heart regeneration relies on the presence of mononuclear diploid cardiomyocytes, which unites this process with embryonic heart growth and adult heart regeneration.

    A synergy-based hand control is encoded in human motor cortical areas

    Andrea Leo et al.
    The human brain encodes coordinated patterns of joint movements – synergies – to increase the efficiency with which it can control complex hand movements.

    High-resolution structures of kinesin on microtubules provide a basis for nucleotide-gated force-generation

    Zhiguo Shang et al.
    Microtubule attachment fundamentally modifies kinesin's behavior by triggering a ‘clamshell’ opening of the nucleotide cleft, subsequently reversed by ATP binding, that couples to cargo translocation.

    Local emergence in Amazonia of Plasmodium falciparum k13 C580Y mutants associated with in vitro artemisinin resistance

    Luana C Mathieu et al.
    The de novo selection of a mutation responsible for Plasmodium falciparum in vitro artemisinin resistance is confirmed in Guyana, making artemisinin combination therapies vulnerable to complete resistance in this region.

    Functional dichotomy in spinal- vs prefrontal-projecting locus coeruleus modules splits descending noradrenergic analgesia from ascending aversion and anxiety in rats

    Stefan Hirschberg et al.
    The locus coeruleus is organised into functional modules with subsets of noradrenergic neurones independently projecting to the spinal cord and prefrontal cortex to exert discrete, antithetical modulatory actions on a range of pain-related behaviours.
