  1. Stepping into the Subjunctive World of the Fiction in Game, Film and Novel.

    Title: Stepping into the Subjunctive World of the Fiction in Game, Film and Novel.
    Creator: Mackey, Margaret
    Description: The concept of the subjunctive mode provides a useful key in exploring narrative comprehension in different media. This article reports on a study in which twelve undergraduates, working in groups of three, read a novel, watched a movie, and played a digital game. Analysis of transcripts of their responses reveals that the role of the subjunctive in their developing awareness of the story is an element that crosses media boundaries and allows forms of cross-media comparison.
    Subjects: subjunctive mode, cross-media comparison, film, game, narrative, novel

  2. Myosin-driven peroxisome partitioning in S. cerevisiae.

    Title: Myosin-driven peroxisome partitioning in S. cerevisiae.
    Creator: Fagarasanu, A.
    Description: In Saccharomyces cerevisiae, the class V myosin motor Myo2p propels the movement of most organelles. We recently identified Inp2p as the peroxisome-specific receptor for Myo2p. In this study, we delineate the region of Myo2p devoted to binding peroxisomes. Using mutants of Myo2p specifically impaired in peroxisome binding, we dissect cell cycle–dependent and peroxisome partitioning–dependent mechanisms of Inp2p regulation. We find that although total Inp2p levels oscillate with the cell cycle, Inp2p levels on individual peroxisomes are controlled by peroxisome inheritance, as Inp2p aberrantly accumulates and decorates all peroxisomes in mother cells when peroxisome partitioning is abolished. We also find that Inp2p is a phosphoprotein whose level of phosphorylation is coupled to the cell cycle irrespective of peroxisome positioning in the cell. Our findings demonstrate that both organelle positioning and cell cycle progression control the levels of organelle-specific receptors for molecular motors to ultimately achieve an equidistribution of compartments between mother and daughter cells.

  3. Scale-eating cichlids: From hand(ed) to mouth.

    Title: Scale-eating cichlids: From hand(ed) to mouth.
    Creator: Palmer, A.R.
    Description: Two recent studies in BMC Biology and Evolution raise important questions about a textbook case of frequency-dependent selection in scale-eating cichlid fishes. They also suggest a fascinating new line of research testing the effects of handed behavior on morphological asymmetry.
    Subjects: scale-eating cichlids, morphological asymmetry, handed behavior, mouth bending

  4. The peroxisomal protein importomer: a bunch of transients with expanding waistlines.

    Title: The peroxisomal protein importomer: a bunch of transients with expanding waistlines.
    Creator: Mast, F.D.
    Description: Peroxisomes can import large multimeric protein complexes and even 9-nm gold particles decorated with peroxisome-targeting signals. They achieve these feats of protein passage using a distinctive translocon whose highly dynamic aqueous pore can expand to accommodate the increasing girths of different peroxisome receptor-cargo complexes.
    Subjects: receptor-cargo complexes, peroxisomes, translocons
