     Evaluation Summary:

     This study investigates the role of acid sensing channels in pH homeostasis required for normal rhythmic muscle contractions in the defecation cycle of C .elegans. It is of importance to scientists with interest in ASIC channel function, pH homeostasis and the cellular mechanisms underlying generation of ultradian rhythms.

     Evaluation Summary:

     Cui et al. colleagues carried out a longitudinal analysis of blood cell counts in a cohort of patients with ALS patients. They found increased numbers of neutrophils and monocytes that negatively correlated with ALSFRS-R score, but not with rate of disease progression. In addition, increased levels in NK and central memory TH2 T cells correlated with a lower risk of death, while increased levels of CD4 CD45RA effector memory and CD8 T cells were correlated with a higher risk of death. These findings have broad implications for ALS pathogenesis and the development of immune-based ALS therapies tailored to specific immune cell populations.

     Evaluation Summary:

     This paper reports a new species of armored dinosaur from rocks in southwestern China dated to the beginning of the Jurassic Period. This represents the first valid species of armored dinosaur from the Early Jurassic in Asia, as although the presence of armored dinosaurs in Asia has been documented for decades based on isolated jaw bones referred to Thyreophora-the group of armored dinosaurs-none that material was complete enough for diagnosis to a known or new species. This new specimen demonstrates the rapid diversification and distribution of armored dinosaurs across the northern hemisphere early in their evolutionary history.

     Evaluation Summary:

     This manuscript addresses a phenomenon of great interest to researchers in cell metabolism and cancer biology: namely, why do cancer cells often secrete high levels of lactate, despite the presence of abundant oxygen to power nutrient oxidation (Warburg effect). The authors propose that lactate export and subsequent extracellular acidification provides a selective advantage and the concomitant rise in intracellular pH is sufficient to drive flux through glycolysis, thereby sustaining the Warburg effect. This is an intriguing hypothesis that ties together many published observations, but it would require further support both from the technical and conceptual side.

     Evaluation Summary:

     Evolution of ageing remains only partially understood, and this research will be of interest to evolutionary biologists, entomologists, or anyone intrigued by senescence. The authors focus on following a large number of ant (C. obscurior) colonies and provide intriguing data in relation to age-specific mortality and reproduction. The gist of their argument is that the mortality is decreasing with age while reproduction (production of sexuals) is increasing with age, such that there is little evidence of ageing in this species. The experimental design is elegant and the data collection thorough, providing insight into the rarely observed final stages of an ant colonies life. The analyses are mostly sound, but the conclusions would benefit from a broader exploration of the structure and constraints inherent to ant societies.

     Evaluation Summary:

     This manuscript reports an open-source platform for the storage and processing of single-molecule, camera-based, imaging data. This platform would facilitate data sharing and reproducibility and would be of great interest to practitioners of single-molecule imaging experiments, both experienced and new to the field. Although the platform requires a bit more testing, troubleshooting, and documenting, it represents significant and important steps towards unifying and standardizing how the field stores and processes data and towards expanding the base of researchers who can easily employ single-molecule imaging methods.

     Evaluation Summary:

     This manuscript addresses the important topic of how changes in gonadal testosterone relate to alterations in gonadal physiology. An important aspect of gonadal testosterone is that it can be an imperfect measure of symptoms related to testosterone deficiency. Therefore, biomarkers that are reflective of testosterone physiology might enable us to more deeply understand the connections between testosterone concentrations and eu- and hypogonadism. The authors performed a proteomic analysis in blood from 30 healthy males at baseline, treated with medical castration and again with testosterone replacement. Associated proteins identified using an unbiased approach were studied further in an independent cohort of 75 hypogonadal and eugonadal men with infertility. Overall, the authors found that 4-hydroxyphenylpyruvate dioxygenase, insulin-like growth factor-binding protein 6 and fructose-bisphosphate aldolase are candidate circulating protein biomarkers. This body of work is certainly novel and should be of interest to the field in hormonal regulation and physiology.

     Evaluation Summary:

     With the increased interest in phage therapy to treat antibiotic resistant infections, there are questions about the ease at which bacteria evolve phage resistance. To examine this, Castledine et al. cultured a set of bacterial isolates from a patient pre- and during phage therapy and also experimentally evolved a mixture of the bacterial isolates from the patient in the absence or presence of phage in vitro. Overall, the authors observed similarities between the evolutionary outcomes (genomic and phenotypic) in the patient and in vitro.

     Evaluation Summary:

     In this manuscript, the authors use long-term population records for 157 mammal species to investigate how populations respond to annual weather anomalies, whether the responses are explained by species' life-history traits, and whether responses vary among species and biomes. They find that populations of shorter-lived species that have larger litter sizes respond more to weather anomalies than longer-lived species with smaller litter sizes. Their results can help understand and predict how different species may respond to climate change, and ultimately, what makes species more sensitive to climate change.

      Evaluation Summary:

      The manuscript by Wang and colleagues expands our understanding of the neural circuit mechanisms underpinning innate sexual behaviors in Drosophila. It exploits an arsenal of sophisticated tools to demonstrate that the neuropeptide Drosulfakinin (DSK) modulates female sexual receptivity via 71G01-neurons > Dsk-m-neurons > CCKLR-17D3 receptor expressing neurons. The study also introduces new transgenic tools that will be valuable for the community and will be of interest to neuroscientists exploring neuropeptide function and female sexual behavior.
