    An atlas of the binding specificities of transcription factors in Pseudomonas aeruginosa directs prediction of novel regulators in virulence

    Tingting Wang et al.
    The transcription factor (TF)-binding specificities of Pseudomonas aeruginosa allow us to predict virulence-associated TFs and their target genes, which will facilitate to find effective treatment and prevention for its associated diseases.

    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.

    Selenium supplementation inhibits IGF-1 signaling and confers methionine restriction-like healthspan benefits to mice

    Jason D Plummer et al.
    Dietary selenium supplementation confers to mice all of the short-term healthspan benefits of the longevity-promoting intervention methionine restriction, and thus may represent a method to promote healthy aging in mammals.
