    A stepped-wedge randomised trial on the impact of early ART initiation on HIV-patients’ economic outcomes in Eswatini

    Janina Isabel Steinert et al.
    A stepped-wedge randomised controlled trial shows that early antiretroviral therapy (ART) initiation does not negatively affect the economic welfare of HIV patients in a low-income country.

    Effects of lifelong testosterone exposure on health and disease using Mendelian randomization

    Pedrum Mohammadi-Shemirani et al.
    Long-term increased testosterone improved body composition and bone density, but lowered HDL and raised risks of hypertension, androgenic alopecia, prostate cancer, and spinal stenosis in males.

    Microbiota-derived short chain fatty acids modulate microglia and promote Aβ plaque deposition

    Alessio Vittorio Colombo et al.
    Experiments in a mouse model for Alzheimer’s disease using germ-free and conventionally housed animals reveal that microbiota-derived short-chain fatty acids promote the deposition of cerebral Aβ plaques.

    Increased longevity due to sexual activity in mole-rats is associated with transcriptional changes in the HPA stress axis

    Arne Sahm et al.
    The fact that sexual activity/reproduction doubles the lifespan of certain rodent species is most likely linked to critical changes in the regulation of the hypothalamic–pituitary–adrenal stress axis.

    Limited dishevelled/Axin oligomerization determines efficiency of Wnt/β-catenin signal transduction

    Wei Kan et al.
    In vitro and in cellulo characterization of oligomerization by the cytoplasmic Wnt effector dishevelled and its partner Axin provide new mechanistic principles for Wnt/β-catenin signaling.

    Effects of water, sanitation, handwashing, and nutritional interventions on telomere length among children in a cluster-randomized controlled trial in rural Bangladesh

    Audrie Lin et al.
    In a randomized controlled trial in rural Bangladesh, an intensive, combined water, sanitation, handwashing, and nutrition intervention delivered to compounds of newborn children increased telomere length attrition during their first year of life.

    Synergy and remarkable specificity of antimicrobial peptides in vivo using a systematic knockout approach

    Mark Austin Hanson et al.
    While antimicrobial cocktails are highly effective for defence against pathogenic microbes, the innate immune response may instead employ highly specific peptidic antibiotics to combat certain natural enemies.

    The Ku subunit of telomerase binds Sir4 to recruit telomerase to lengthen telomeres in S. cerevisiae

    Evan P Hass, David C Zappulla
    In yeast, the secondary pathway for recruiting telomerase to chromosome ends requires a component of telomeric transcriptionally silent chromatin.

    Transient rapamycin treatment can increase lifespan and healthspan in middle-aged mice

    Alessandro Bitto et al.
    Three months treatment with the drug rapamycin increases lifespan, alters cancer prevalence, remodels the microbiome, and improves functional measures of health in middle aged mice in a dose- and sex-dependent manner.

    A predictive focus of gain modulation encodes target trajectories in insect vision

    Steven D Wiederman et al.
    Visual neurons in the dragonfly predict the path of a moving target, even when it is occluded or crosses from one eye to the other.
