     Evaluation Summary:

     The study addresses a topic that is timely and of general interest. The findings represent a potentially very interesting contribution to the important question of how the brain comes to predict the future, in particular lifelike sequences of events. However, some of the main conclusions would require further statistical support.

     Evaluation Summary:

     The present study uses innovative approaches to further our knowledge of skin immunobiology. The corresponding results explain the expression of langerin on two fractions of dermal DC (CD103+ and CD103-) observed several years ago. The demonstration that epidermal LC do not contribute to LN populations in the steady state is completely unexpected and raises important questions about the in vivo function of the LC-like subset unveiled in the present study.

     Summary: In this paper, the authors proposed a new approach by mounting a PDMS microwells of specific sizes on agar surface to confine swarming and planktonic SM3 cells. They found swarming bacteria exhibit a "single-swirl" motion pattern and concentrated planktonic bacteria exhibit "multi-swirls" motion pattern in the diameter range of 31-90 μm. The phase diagram shows that in smaller wells concentrated planktonic SM3 forms a single vortex and in larger wells swarming SM3 also breaks into mesoscale vortices.

     In addition, they conducted systematic experiments to explore parameters defining the divergence of motion patterns in confinement including cell density, cell length, cell speed and surfactant. They concluded that the single swirl pattern depends on cohesive cell-cell interaction mediated by biochemical factors removable through matrix dilution.

     This paper gives a new method to discern swarmers from planktonic bacteria and carefully studies the factors that influence the formation of bacterial vortices under restriction.

     Summary:

     The reviewers agreed that the paper provides strong in vivo data for a tumor-suppressive role for Mga in lung carcinogenesis. The authors convincingly show that MGA is important in oncogenesis. We note here that MGA is highly understudied (~200 publications) in and of itself despite its involvement with the MYC network for oncogenesis (~41,000 publications at the current time). Given a protein of 3000 amino acids, the number of potential protein partners and PTMs that might modify its tumor suppressor functions are staggering. However, the reviewers also noted that a previous paper has addressed the same topic and the novelty of the data presented here needs to be better explained and additional experiments are needed to strengthen and expand the new aspects.

     Summary:

     In this manuscript the authors perform a retrospective analysis in attempt to delineate the role of goal-directed versus habitual mechanisms underlying choice between drug and non-drug rewards. Specifically, the authors utilized data generated in their laboratory to assess cocaine-versus-saccharin choice following limited and extended training paradigms. A sequential choice model was used to assess the prediction that increased latencies during choice reflect goal-directed control; whereas no change in latencies reflects habitual control. Based on this model, the authors report that rats engage in goal-directed control after limited training, and adopt more habitual responding after extended training. The authors conclude that the sequential choice model is specific to habitual choice.

     While the Reviewers appreciate the approach and conceptual framework described in this manuscript, they are all in agreement that additional data and analyses are needed to better support the claims surrounding goal-directed versus habitual control of reward-seeking behavior. For example, an independent evaluation of whether the target behavior is in fact goal-directed or habitual seems necessary to support such claims. Reviewers’ comments and suggestions for improvement are included below.

      Evaluation Summary:

      In their manuscript titled "Archaeal chromatin 'slinkies' are inherently dynamic complexes with deflected DNA wrapping pathways", Bowerman et al. use an elegant combination of cryo-EM, analytical ultracentrifugation and molecular dynamics simulations to investigate the structure and dynamics of archaeal histone — DNA complexes, termed archaeasomes to distinguish them from eukaryotic nucleosomes. This study builds upon the crystal structure of an archaeasome and the functional analysis of its disruption recently published by the same group (Mattiroli et al, 2017) by analyzing the dynamics of this complex and discussing how these dynamics could relate to archaeal genome biology. How chromatin evolved is a fundamental question in biology, marking a striking departure from the bacterial nucleoid. This current manuscript describes a rigorous biophysical study that not only provides substantial new insights into archaeal genome biology but also raises intriguing questions for future study. This manuscript will therefore no doubt be of interest not only to the archaeal research community but also to the field of chromatin biology.
