    Hedgehog signaling is required for endomesodermal patterning and germ cell development in the sea anemone Nematostella vectensis

    Cheng-Yi Chen et al.
    The dependence of Nematostella germ cell specification on zygotic Hedgehog pathway activity supports the hypothesis that the eumetazoan common ancestor segregated its germline by inductive signals rather than maternal determinants.

    The Mla pathway in Acinetobacter baumannii has no demonstrable role in anterograde lipid transport

    Matthew J Powers et al.
    An outer membrane vesicle pulse-chase assay demonstrates that the Acinetobacter baumannii Mla system is a retrograde lipid transporter.

    Efficient sampling and noisy decisions

    Joseph A Heng et al.
    An efficient coding theory for higher-level cognitive processes reveals that humans efficiently adapt to contextual distributions by economizing on environmental prior information.

    A regulatory pathway that selectively up-regulates elongasome function in the absence of class A PBPs

    Yesha Patel et al.
    Balanced peptidoglycan synthesis requires regulators, including sigma-I and WalKR, that coordinate the diffusive action of class A PBPs and the directional motion of the MreB-directed elongasome.

    Direct reprogramming of human smooth muscle and vascular endothelial cells reveals defects associated with aging and Hutchinson-Gilford progeria syndrome

    Simone Bersini et al.
    Direct reprogramming of smooth muscle cells from HGPS patients revealed that BMP4 is a key contributor of vascular degeneration and might represent a new therapeutic target.

    CD163 and pAPN double-knockout pigs are resistant to PRRSV and TGEV and exhibit decreased susceptibility to PDCoV while maintaining normal production performance

    Kui Xu et al.
    The double-gene-knockout pig is a valuable model to help understand the mechanisms of CD163 and pAPN in the infection of multiple viruses and offers excellent breeding materials for disease-resistant pigs.

    Measuring protein stability in the GroEL chaperonin cage reveals massive destabilization

    Ilia Korobko et al.
    Protein stability in the cage formed by the chaperonin GroEL and its cofactor GroES is reduced by more than 5 kcal mol-1 relative to that in bulk solution.

    Vibrio deploys type 2 secreted lipase to esterify cholesterol with host fatty acids and mediate cell egress

    Suneeta Chimalapati et al.
    Considering the course of a pathogen's evolution, there appears to be interplay between secretion systems, providing unique, synergistic mechanisms to support a successful lifestyle for possibly pathogenesis, symbiosis and/or parasitosis.

    Estrogen exacerbates mammary involution through neutrophil-dependent and -independent mechanism

    Chew Leng Lim et al.
    Estrogen aggravates mammary involution through lysosome-mediated cell death, neutrophil recruitment via CXCR2 signalling, neutrophil-mediated inflammation and adipocyte repopulation.

    Concentration-dependent mortality of chloroquine in overdose

    James A Watson et al.
    Most chloroquine regimens trialled for the treatment of COVID19 will not result in life-threatening cardiovascular toxicity.
