     Evaluation Summary:

     This important and exciting paper demonstrates that the blind cavefish, known for its lack of eyes and increased number of lateral line hair cells, also exhibit physiological adaptations to increase lateral line sensitivity. The authors demonstrate that these adaptations have convergently evolved in multiple populations that have independently colonized cave environments. By leveraging the numerous strengths of the cavefish model, the authors are able to show precisely how neural circuits can be affected by adaptation to the environment.

     Evaluation Summary:

     The process of secretory vesicle formation, transport, and fusion in yeast has mainly been characterized through biochemical and genetic means. Only limited information was available about the detailed timeline and order of events. This study fills the gap with a high-resolution temporal analysis, which provides new insights into when key components arrive and depart and how they promote vesicle tethering and fusion. The work is experimentally strong, and improvements to the presentation will ensure that the findings are communicated effectively.

     Evaluation Summary:

     This paper describes a microfluidic approach to determine the viscoelastic properties of living cells from their deformation in a fluid flow. Its implementation seems accessible and the method offers the possibility to perform measurements on a large number of cells. This technique could eventually be used in many laboratories, including those not specialized in cell mechanics.

     Evaluation Summary:

     The premise behind this manuscripts is that concepts from thermodynamics and statistical mechanics can be used to understand brain states and the transitions between such states, just like it is done with transitions between solid and liquid states in well define thermodynamic systems. While this is an interesting attempt to use thermodynamic concepts and equations to analyze fMRI signals, the legwork needed to meaningfully translate those concepts to understand their actual physiological meaning and their relationship to brain function has not yet been achieved.

     Evaluation Summary:

     The paper describes a re-analysis of a public fMRI data set which includes measures of resting state connectivity and separate task-based scans of memory encoding and memory retrieval tasks. The paper proposes an analysis method termed "information transfer" that reveals functional interactions between various brain networks during encoding and retrieval as well as differences in these interactions during encoding vs. retrieval. While the methods are potentially interesting, the payoff-or new insight afforded by these methods compared to existing methods-is not fully established.

     This paper provides a comprehensive co-mutation analysis of over 30 thousand cancer patients and 1700+ cancer cell lines to identify associations with prognosis and drug resistance that could have translational value for clinical practice. Once validated, it would provide a useful framework for precision oncology.

     Evaluation Summary:

     This work provides an insightful analysis of how animals can use different types of sniffing to quickly find the sources of odorants in natural, often turbulent, environments. As it turns out, the air near the ground is less turbulent but does not provide high precision information about the location of sources that are far away. To get that kind of information, animals have to pause and sniff in the air. Authors show that the relative balance between sniffing near the ground and in the air shifts as the animals approach the source and that this shift matches optimal strategies that can be pursued based on partially observable statistical models of the environment. The paper also includes a very useful set of simulations of odorant flow in the presence of obstacles that will be made publicly available.

     Evaluation Summary:

     The manuscript studies the heterogeneity of megakaryocytes using single cell RNA-seq and identifies a subpopulation of CXCR4-high megakaryocytes with immune modulatory roles. The authors also perform functional studies which show that this subpopulation of megakaryocytes promotes bacterial phagocytosis by macrophages and neutrophils. This work would be of significant interest to researchers in the fields of immunology and host defense as well as researchers studying hematopoiesis and megakaryocyte biology because it provides new perspectives on megakaryocyte heterogeneity as well as the role of megakaryocytes in host defense and immune function.

9. Prefrontal PV interneurons facilitate attention and are linked to attentional dysfunction in a mouse model of absence epilepsy

     Evaluation Summary:

     The manuscript by Ferguson and Huguenard examined the mechanism underlying attentional deficits in the haploinsufficient Scn8a mouse model of absence epilepsy. Using a detection behavior paradigm where detection of the cue was dependent on the attention level, they show that Scn8a+/- mice perform worse than controls when cues are of intermediate duration. In the medial prefrontal cortex (mPFC), high gamma-band power, which is presumed to be mediated by activity in parvalbumin-positive (PV+) interneurons, was reduced in Scn8a+/- mice, but optogenetic stimulation of these neurons at low gamma-frequency normalized performance on the cue-based attention task. The results of this study identify mPFC PV dysfunction, rather than seizure activity, as a potentially important cellular substrate, for attention during cue-presentation.

      Evaluation Summary:

      This ms examines changes in brain region size in several groups of weakly electric fishes, the Mormyroidea, and the Gymnotiformes and weakly electric catfishes (Synodontis spp.), which evolved electroreception independently of mormyrids. These are an interesting group for examination of mosaic growth. Many analyses are thoughtful and well executed, but there is some concern about whether the observed volumetric decreases are a consequence of the method.
