    Autocatalytic microtubule nucleation determines the size and mass of Xenopus laevis egg extract spindles

    Franziska Decker et al.
    Quantitative microscopy and theory show that the size of Xenopus laevis egg extract spindles is controlled by a spatially-regulated autocatalytic growth mechanism driven by microtubule-stimulated microtubule nucleation.

    Activity of the C. elegans egg-laying behavior circuit is controlled by competing activation and feedback inhibition

    Kevin M Collins et al.
    The neural circuit that regulates egg-laying behavior in nematode worms is activated by egg production, coupled to the circuit that generates movement, and inhibited by sensory feedback from egg release.

    Adaptive thermal plasticity enhances sperm and egg performance in a model insect

    Ramakrishnan Vasudeva et al.
    Sperm and egg development are temperature sensitive, enabling males and females to significantly improve their reproductive success by matching gamete function to varying thermal environments for fertilisation and offspring development.

    Optical detection of three modes of endocytosis at hippocampal synapses

    Natali L Chanaday, Ege T Kavalali
    Single synaptic vesicle imaging shows that kinetically distinct endocytic pathways are differentially regulated by calcium and temperature, and influence the fidelity of synaptic vesicle protein retrieval.

    Single synapse evaluation of the postsynaptic NMDA receptors targeted by evoked and spontaneous neurotransmission

    Austin L Reese, Ege T Kavalali
    In a population of mammalian central synapses, spontaneous and evoked neurotransmitter release processes are independently distributed; yet, postsynaptic receptors within a single synapse preferentially receive neurotransmitter from only one mode of release.

    Spontaneous neurotransmission signals through store-driven Ca2+ transients to maintain synaptic homeostasis

    Austin L Reese, Ege T Kavalali
    Individual neurons can adjust the strength of their synapses by using spontaneous calcium influx through NMDA receptors to trigger the release of additional calcium from intracellular stores, which can in turn be used to regulate protein synthesis.

    The kinetoplastid-infecting Bodo saltans virus (BsV), a window into the most abundant giant viruses in the sea

    Christoph M Deeg et al.
    Bodo saltans virus defines the most abundant giant viruses in the ocean and highlights the genomic plasticity, rooted in evolutionary arms races, that gave rise to giant viruses.

    Human VMPFC encodes early signatures of confidence in perceptual decisions

    Sabina Gherman, Marios G. Philiastides
    Simultaneous EEG-fMRI reveals neural representations of decision confidence unfolding prior to explicit perceptual choices, in a region of the ventromedial prefrontal cortex typically linked to reward processing and value-based decisions.

    MutSα maintains the mismatch repair capability by inhibiting PCNA unloading

    Yoshitaka Kawasoe et al.
    Biochemical analysis in Xenopus egg extracts reveals that the MutSα mismatch sensor retains the DNA-bound replication clamp to maintain a post-replicative temporal window permissive to strand-specific repair of mismatches.

    Lamina-specific cortical dynamics in human visual and sensorimotor cortices

    James J Bonaiuto et al.
    Cortical oscillations in human MEG are lamina-specific, with low-frequency activity predominating in deep, and high-frequency activity in more superficial layers of sensory and motor cortices.
