     Evaluation Summary:

     This paper is of interest to researchers studying cardiac regeneration and regeneration in general. Given the multiple papers characterizing interstitial cell types during mammalian cardiac injury response, this type of characterization in one of the leading regeneration model systems is overdue. The authors utilize single cell sequencing approaches to identify dynamics and key features of interstitial cell populations during zebrafish cardiac regeneration, which largely supports the claims of the paper. The data presented here have the potential to serve as a valuable reference resource for future studies, although some of the conclusions, in particular those on the function of tal1 and mmp14, are not yet sufficiently supported by data.

     Evaluation Summary:

     This work analyzes how meaningful connections develop in the nervous system. Studying the dissociated neuronal cultures, the authors find that the information processing connections develop after 5-10 days. The direction of the information flow is influenced by neuronal bursting properties: the early bursting neurons emerge as sources and late bursting neurons become sinks in the information flow.

     Evaluation Summary:

     This manuscript reports that ppGpp accumulation is necessary for acclimation to nitrogen starvation in a model plant Arabidopsis. The authors also showed a ppGpp-mediated downregulation of chloroplast gene transcription and a coordinated plastid-nuclear gene expression under nitrogen deficiency. This represents a solid new step in our understanding of plant responses to nitrogen-limiting conditions as well as on the role of ppGpp in plants and possibly throughout the green lineage.

     Evaluation Summary:

     The study presents novel results on spontaneous fluctuations in pupil dilation in relation to the spectral dynamics in a large sample of human participants. The study is based on MEG recordings allowing for quantifying these relations in time and space. The data provide important new insight into the temporal and spatial characteristics of pupil-linked changes in cortical states which form the basis for incorporating this insight in future clinical and cognitive neuroscience studies.

     Evaluation Summary:

     This manuscript studies a topic of interest to developmental biologists using a combination of optogenetics, biophysical concepts, and mathematical modeling. How in plane contractile forces cause out of plane shape changes is a relevant open question, and the optogenetic tools developed in this work provide a new strategy to address the question.

     Evaluation Summary:

     The possibility that local or systemic hypoxia regulates aspects of the immune system has attracted widespread interest over the last decade or more. Previous work has implicated regulatory T cells in at least some of these responses, and has demonstrated that over-activation of a specific hypoxia inducible factor (HIF) isoform, HIF-2alpha has the potential to driven pro-inflammatory lymphoproliferative responses characterized by defective regulatory T cells. The current work demonstrates that genetic activation of these hypoxia-signalling pathways that is restricted to the regulatory T cell lineage is sufficient to drive this type of immune activation. The work is important since it provides a focus for study of the mechanism, for which the authors make a proposal based on mis-localization of regulatory T cells. It is also important in focussing a key questions (requiring further study) as to whether physiological or pathological hypoxia, specifically affecting these cells, will drive such a response and/or whether the lymphoproliferative phenotype could be affected adversely or beneficially by agents that are being used to upregulate or downregulate hypoxia-signalling pathways in other settings.

     This manuscript from Bishop et al aims to quantify the hypoxic and hyperoxic ventilatory response in the marmoset, an increasingly more common primate research model. The strongest contribution of the paper is the presentation of an analysis toolkit to perform unsupervised analyses of respiratory data, which are not widely available.

     Evaluation Summary:

     This is an intriguing study using cleverly designed stimuli to investigate the representation of physical stability in the human brain. This paper will be of interest to readers wondering when human cognition uses generalizable pattern matching similar to that used by machine learning algorithms, and when it relies on more specialized processes evolved for specific tasks. The well-crafted experiments generally support the authors' major claim.

      Evaluation Summary:

      This manuscript describes the presence of two discernable populations of pancreatic delta cells in a zebrafish model. One of these subsets of delta cells is suggested to facilitate the regeneration of functional beta cell mass following beta cell ablation. This observation is of interest to investigators studying islet regeneration.
