    SCGN deficiency results in colitis susceptibility

    Luis F Sifuentes-Dominguez, Haiying Li ... Ezra Burstein
    A novel mutation in SCGN is associated with risk for inflammatory bowel disease and implicates the intestinal neuroendocrine compartment in the pathogenesis of this disorder.

    Unified bursting strategies in ectopic and endogenous even-skipped expression patterns

    Augusto Berrocal, Nicholas C Lammers ... Michael B Eisen
    Drosophila melanogastereven-skipped enhancers control transcriptional bursting by modulating frequency and amplitude, regardless of varying transcription factor inputs, even when mutated to express in embryonic regions not under selective pressure.

    Structures reveal opening of the store-operated calcium channel Orai

    Xiaowei Hou, Shana R Burstein, Stephen Barstow Long
    The structure of the calcium channel Orai in an open conformation reveals a dilated pore and gives insight into mechanisms of ion permeation and calcium selectivity.

    A continuum model of transcriptional bursting

    Adam M Corrigan, Edward Tunnacliffe ... Jonathan R Chubb
    Rather than switching between discrete on and off states, gene transcription exists in a spectrum or continuum of states, with a slowly changing initiation rate modulating the levels of activity.

    Mixed-mode oscillations and population bursting in the pre-Bötzinger complex

    Bartholomew J Bacak, Taegyo Kim ... Ilya A Rybak
    Computational modeling reveals the mechanisms by which a diverse group of neurons in the brainstem generates rhythmic breathing in mammals.

    Climate-mediated cooperation promotes niche expansion in burying beetles

    Syuan-Jyun Sun, Dustin R Rubenstein ... Sheng-Feng Shen
    Cooperation enables burying beetles to outcompete flies and adapt to a wider range of temperatures as thermal generalists.

    Dopamine enhances model-free credit assignment through boosting of retrospective model-based inference

    Lorenz Deserno, Rani Moran ... Raymond J Dolan
    Cooperation between model-free and model-based control systems is boosted by enhancing dopamine levels.

    Localization of spontaneous bursting neuronal activity in the preterm human brain with simultaneous EEG-fMRI

    Tomoki Arichi, Kimberley Whitehead ... Lorenzo Fabrizi
    Direct measure of neural and hemodynamic activity in the developing human brain shows that the insula is a major source of transient bursting events that are critical for cortical maturation.
