    An aging-independent replicative lifespan in a symmetrically dividing eukaryote

    Eric C Spivey et al.
    A high throughput, full lifespan microscopic analysis reveals that fission yeast does not age but has a finite replicative lifespan.

    True S-cones are concentrated in the ventral mouse retina and wired for color detection in the upper visual field

    Francisco M Nadal-Nicolás et al.
    Unique 'true' S-cone and S-cone bipolar cell distribution patterns in the mouse retina are previously unappreciated anatomical features that support enhanced short-wavelength signaling for color detection above horizon.

    Mouse rods signal through gap junctions with cones

    Sabrina Asteriti et al.
    Electrophysiological recordings show that cones in the eyes of mice are able to receive strong input from rods via gap junctions, supporting the view that this route plays an important role in vision.

    Novel ATP-cone-driven allosteric regulation of ribonucleotide reductase via the radical-generating subunit

    Inna Rozman Grinberg et al.
    Structural and functional characterization of an unanticipated mode of allosteric activity regulation in ribonucleotide reductases controlled by an ATP-cone in the radical-generating subunit.

    Organisms with alternative genetic codes resolve unassigned codons via mistranslation and ribosomal rescue

    Natalie Jing Ma et al.
    Cells resolve unassigned codons with near-cognate suppression, frameshifting, and ribosomal rescue mechanisms, demonstrating that unassigned codons are permissible in both natural and engineered genetic codes as barriers to horizontal gene transfer.

    Noninvasive quantification of axon radii using diffusion MRI

    Jelle Veraart et al.
    Cell-specific architectural properties such as the axon diameter of the white matter of the human brain can be quantified accurately and non-invasively using diffusion magnetic resonance imaging.

    The rate of transient beta frequency events predicts behavior across tasks and species

    Hyeyoung Shin et al.
    Across species, tasks and recording modalities, the rate of transient neocortical beta frequency (15-29Hz) events strongly predicts perceptual ability, providing fundamental mechanistic insight, with implications for tracking and manipulating brain dynamics.

    Akt1-Inhibitor of DNA binding2 is essential for growth cone formation and axon growth and promotes central nervous system axon regeneration

    Hyo Rim Ko et al.
    Akt mediated S14 phosphorylation of Id2 augments its protein stability and growth cone localization, promoting growth cone formation and axon growth in the developing neuron and contributing to axon regeneration in the damaged hippocampus slice.

    Learning precise spatiotemporal sequences via biophysically realistic learning rules in a modular, spiking network

    Ian Cone, Harel Z Shouval
    A computational model shows that it's possible to learn and replay extended temporal sequences in a network of spiking neurons with a modular architecture and a biologically realistic learning rule.

    The Na+/Ca2+, K+ exchanger NCKX4 is required for efficient cone-mediated vision

    Frans Vinberg et al.
    Molecular, genetic, and functional analysis is used to show that the olfactory Na+/Ca2+, K+ exchanger NCKX4 is expressed in cone photoreceptors and is critical for the wide operating range and high temporal resolution of cone-mediated vision.
