    Erythropoietin signaling regulates heme biosynthesis

    Jacky Chung et al.
    EPO/JAK2/PKA signaling cascade via AKAP10 relocalization to the outer mitochondrial membrane results in the phosphorylation of the terminal heme synthesis enzyme ferrochelatase, which contributes to heme production in red cells.

    Chemotactic network responses to live bacteria show independence of phagocytosis from chemoreceptor sensing

    Netra Pal Meena, Alan R Kimmel
    Eukaryotic chemotaxis to live bacteria was quantified at a high throughput level, for the first time, and mechanistically examined for the interrelationship between chemotaxis and phagocytosis.

    Sec17/Sec18 act twice, enhancing membrane fusion and then disassembling cis-SNARE complexes

    Hongki Song et al.
    Sec17 (αSNAP) and Sec18 (NSF) are shown to act twice, to promote fusion per se and to recycle SNAREs after fusion.

    Mechanosensory neurons control the timing of spinal microcircuit selection during locomotion

    Steven Knafo et al.
    Bioluminescence monitoring and selective silencing in zebrafish larva reveal a novel sensorimotor circuit modulating speed in the moving spinal cord.

    Chronic pain induces generalized enhancement of aversion

    Qiaosheng Zhang et al.
    Chronic pain distorts intensity coding in the anterior cingulate cortex to give rise to generalized anatomically nonspecific enhancement in pain aversion.

    Epidemiology: Promiscuous bacteria have staying power

    Ruth C Massey, Daniel J Wilson
    Being able to take up DNA from their environment might allow pneumococcal bacteria to colonize the human nose and throat for longer periods of time.

    Cell cycle entry triggers a switch between two modes of Cdc42 activation during yeast polarization

    Kristen Witte et al.
    Optogenetic control of Cdc42 activation during polarization of budding yeast demonstrates a cell cycle regulated switch between two distinct modes of positive feedback.

    Effects of myosin variants on interacting-heads motif explain distinct hypertrophic and dilated cardiomyopathy phenotypes

    Lorenzo Alamo et al.
    Mapping the locations of hypertrophic cardiomyopathy gene variants onto the three-dimensional structures of contractile proteins revealed that these disrupt protein interactions are critical for normal cardiac relaxation and efficient energy usage.
