    Super Spy variants implicate flexibility in chaperone action

    Shu Quan et al.
    Lab-evolved 'super Spy' chaperones show enhanced flexibility, which allows them to bind to and stabilize proteins more effectively than natural chaperones.

    Central Dicer-miR-103/107 controls developmental switch of POMC progenitors into NPY neurons and impacts glucose homeostasis

    Sophie Croizier et al.
    Loss miRNA maturation in proopiomelanocortin (POMC) neurons causes metabolic dysregulation and favors the differentiation of Pomc progenitors into neuropeptide Y neurons, a developmental process that appears to specifically involve miR-103/107.

    Sustained NPY signaling enables AgRP neurons to drive feeding

    Yiming Chen et al.
    A specific neuropeptide is responsible for the ability of AgRP neurons to generate long-lasting hunger.

    Antagonistic modulation of NPY/AgRP and POMC neurons in the arcuate nucleus by noradrenalin

    Lars Paeger et al.
    The coordinated differential modulation of satiety signaling POMC- and hunger signaling AgRP- neurons in the arcuate nucleus of the hypothalamus assigns an important role to noradrenalin to promote feeding.

    Non-enzymatic primer extension with strand displacement

    Lijun Zhou et al.
    Relying on RNA fragments derived from degradation or partial template copying, non-enzymatic primer extension with strand displacement offers a novel and prebiotically plausible approach to RNA self-replication.
