     Rodberg et al. show systemic β adrenergic antagonism reduces engagement in decision-making, particularly in female rats, and reduces task-related encoding in neural activity. This is a valuable finding that addresses a gap in the field, however, the understanding of the direct contribution of β adrenergic receptors to the observed effects is incomplete. Further, the theoretical grounds, data analyses, and results could be improved in several ways.

     This work provides fundamental new insight into fine axonal morphologies based solely on extracellular action potential recordings. They provide compelling evidence of fine resolution in mapping functional connections between neurons. The work may have broad use in neurobiology, bioengineering, stem cell biology, as well as tissue engineering in functional characterization.

     This important paper provides web based interface for cross-tissue analysis of omics datasets from – so far – two different human populations, with compelling evidence that the tool can be used to make meaningful scientific discoveries. Conceptually, these analyses are relevant for any systems biologist or bioinformatician who is interested in integrating large population datasets. Currently, the resource is already of use for scientists studying the HMDP or using GTEx data, and we hope to see updates in the coming years that incorporate more populations and more datatypes, which could make it a general tool for a wide community.

     The manuscript represents an important contribution to an ongoing discussion about the substrate binding site and mechanism of the Bile Acid Sodium Symporter (BASS) family of transporters. Structural and biochemical analysis of a bacterial homolog, ASTBnm, in complex with its native substrate (not bile acids, but a vitamin A precursor, pantoate) show a new binding site that is consistent with classical proposals for elevator-type transport mechanisms. Molecular dynamics (MD) simulations highlight the improved stability for the substrate in the active site when ions are present, suggesting a binding order during the transport cycle. The structural studies, binding assays, and MD simulations are convincing.

     This fundamental study significantly advances our understanding of how parasites evade the host complement immune system. The new cryo-EM structure of the trypanosome receptor ISG65 bound to complement component C3b is highly compelling and well-supported by biochemical experiments. This work will be of broad interest to parasitologists, immunologists, and structural biologists.

     This study identifies two new transporters in the apicoplast, a non-photosynthetic organelle of apicomplexan parasites. While this is important work, it only partially reveals how essential these transporters are, as it does not address the metabolic function of the transporters for the parasite. Although the evidence is still incomplete, the results should be of interest to parasitologists and eukaryotic cell biologists.

     This study includes fundamental findings on protein evolution, namely that changes in function are largely attributable to pairwise rather than higher-order interactions, and that epistasis potentiates rather than constrains evolutionary paths. Compelling evidence supporting the conclusions is provided by applying a new model to a previously generated experimental dataset on deep mutational scanning of the DNA-binding domain (DBD) of steroid hormone receptor. The implications of this work are of considerable interest to protein biochemistry, evolutionary biology, and numerous other fields.

     This valuable work on the paleovegetation history of Iceland has implications for the field of paleoecology, and the deglaciation history of Iceland and additional localities in Northern America and Europe via woody shrub colonization. The study uses a sedimentary ancient DNA metabarcoding approach to study this historic process. The strength of evidence is solid, with the methods (analysis of sedimentary DNA) and data analyses broadly supporting the claims.

     This important study examined the use of dantrolene, a Ryanodine Receptor stabilizer, in slowing pathological progression of pressure-overload heart failure in a guinea pig model and reducing arrhythmias. Convincing data were collected and analyzed using validated methodology and can be used as a starting point for future studies of dantrolene in Ca2+ handling in ROS production and further deterioration of cardiac function in chronic heart failure.

      The paper represents a novel application of recursion theory to the long call vocalisations of orangutans to demonstrate repetitive, rhythmic sub-structuring. The authors use detailed acoustic analyses to show compelling evidence for self-embedded and nested isochronic motifs. These fundamental results have the potential to significantly advance current approaches used to compare nonhuman communication systems with human language.
