  1. Research Culture: Creating SPACE to evolve academic assessment

    Ruth Schmidt et al.
    The San Francisco Declaration on Research Assessment (DORA) has developed a new tool called SPACE to support universities and institutions working to improve the assessment of research.

    Dorsal periaqueductal gray ensembles represent approach and avoidance states

    Fernando MCV Reis et al.
    Distinct dorsal periaqueductal gray ensembles encode threat approach and avoidance behavioral states.

    Distinct cytoskeletal proteins define zones of enhanced cell wall synthesis in Helicobacter pylori

    Jennifer A Taylor et al.
    The helical bacterium Helicobacter pylori patterns cell wall synthesis using two distinct cytoskeletal proteins, CcmA and MreB, to achieve its characteristic shape.

    Dorsal premammillary projection to periaqueductal gray controls escape vigor from innate and conditioned threats

    Weisheng Wang et al.
    Activity in the hypothalamic dorsal premammillary nucleus predicts future escape from threat, represents escape velocity, and controls escape velocity via a projection to the brainstem.

    Innovation of heterochromatin functions drives rapid evolution of essential ZAD-ZNF genes in Drosophila

    Bhavatharini Kasinathan et al.
    Heterochromatic sequences evolve rapidly, as do ZAD-ZNF genes-encoding proteins involved in heterochromatin functions, explaining why evolutionarily dynamic ZAD-ZNF genes are more likely to be essential in Drosophila.

    Computational modeling identifies embolic stroke of undetermined source patients with potential arrhythmic substrate

    Savannah F Bifulco et al.
    In models reconstructed from MRI scans of patients with embolic stroke of undetermined source, computational simulations reveal that fibrosis has the intrinsic capacity to sustain arrhythmia drivers when subjected to triggered activity known to exist in patients with atrial fibrillation.

    A bipartite iron-dependent transcriptional regulation of the tryptophan salvage pathway in Chlamydia trachomatis

    Nick D Pokorzynski et al.
    Analysis of the atypical tryptophan biosynthetic operon of Chlamydia trachomatis revealed the simultaneous regulation of transcriptional initiation and termination by an iron-dependent repressor, expanding known regulatory mechanisms of this pathway.

    Pharmacologic ATF6 activating compounds are metabolically activated to selectively modify endoplasmic reticulum proteins

    Ryan Paxman et al.
    The small molecule, 147, is a pro-drug that preferentially activates ATF6 signaling through a mechanism involving localized metabolic activation and selective covalent modification of ER resident proteins involved in regulating ATF6 activity.

    Hypothemycin, a fungal natural product, identifies therapeutic targets in Trypanosoma brucei

    Mari Nishino et al.
    Hypothemycin, which inhibits a number of protein kinases, kills the T. brucei parasites that cause sleeping sickness and reveals new therapeutic targets for the disorder.

    Non-genetic inheritance restraint of cell-to-cell variation

    Harsh Vashistha et al.
    Quantitative measurement of epigenetic memory and inheritance dynamics.
