     This is an important manuscript that will be of interest to a broad range of researchers studying immunology, obesity and metabolism, as well as the links between maternal health and pathophysiological responses in the offspring. The comprehensive studies using RNA-seq, scRNA-seq, ATAC-seq and scATAC-seq in human umbilical cord monocytes represent an important resource for understanding the transcriptomic and epigenetic shifts in the monocytes of newborns. The experiments involving stimulation of monocytes with pathogens offer convincing evidence for the dysfunction of monocytes in the newborn.

     Evaluation Summary:

     Chen et al. demonstrate a pro-survival role of the NRF2/DKK1 axis in mesenchymal stem cells. Furthermore, the authors provide evidence that targeting this pathway can enhance survival in response to liver failure in vivo. These data highlight a novel signaling pathway to enhance efficacy of MSCs in promoting regeneration.

     Evaluation Summary:

     Carboxysomes enable the efficient fixation of carbon dioxide in specific bacteria. Phase separation has been invoked as a mechanism that drives the formation of carboxysomes. The current work focuses on the biophysical principles of how one of two essential specific protein components enable spatial regulation over carboxysomes. This important work highlights the connection between oligomerization via specific molecular interactions and phase separation. The work is of interest to the areas of biochemistry and carbon dioxide fixation as well as phase separation.

     Evaluation Summary:

     Drosophila ovarian follicle cells have been utilized as a model system to study organogenesis and epithelial tumorigenesis. The analysis of single-cell transcriptomes of follicle cells now shows that transcriptionally distinct cell populations emerge shortly after induction of loss of polarity. Strengths of the work include the use of advanced single cell omics and imaging analyses to identify cell types and factors playing a role the disruption of polarity and the implications of this work for epithelial cancers. The authors' claims are generally well supported by the data and analyses. Weaknesses include the lack of high magnification images and need to clarify motivation for the study and highlight the biology rather than technical advances in the results section. Overall, this work is viewed as an important contribution to cell biologists who work on the epithelial morphogenesis or tumorigenesis.

     Evaluation Summary:

     This manuscript addresses G protein-coupled receptor signaling and proposes an additional site on Beta-arrestin2 (arrestin 3) as being responsible, in significant part, for the downregulation and likely onward signalling from endosomes of a range of GPCRs. The cell biology appears to be thoroughly carried out and data presented in a statistically appropriate manner. With some textual changes and minor experimental clarification of the route taken and molecules involved, this work will be of broad interest.

     eLife assessment

     This paper provides evidence that an unhealthy lifestyle during adolescence accelerates epigenetic age in adulthood, and that these associations are largely explained by the effect of shared genetic influences. The main strengths of this valuable paper are the relatively large sample size, longitudinal assessment of lifestyle factors, and sophisticated statistical analyses. The paper is methodologically compelling and will be of interest for a broad audience, including individuals working on methylation, epidemiology, and/or ageing.

     Evaluation Summary:

     The authors use high spatial resolution MEG in humans to link two important components (time - transient bursts, space - waves) of neural sensorimotor dynamics by investigating how transient beta bursts propagate in the brain. The authors find two directions of propagating waves during beta bursts. The work links two fundamental aspects of neural dynamics which may yield new insights into the origins of sensorimotor behavior, with wide appeal to neuroscientists and clinicians. The reviewers considered the methodological work largely sound, although concerns were raised by the reviewers to what extent the travelling waves correspond to underlying neural activity or reflect the generative nature of field potentials.

     Evaluation Summary:

     This paper will be of interest to researchers studying meniscus homeostasis and knee osteoarthritis. It uncovers distinct subtypes of cell populations in inner and outer part of human meniscus using single-cell RNA sequencing. In particular, this work further identifies how alterations in meniscal cell populations may contribute to inflammation and osteoarthritis and thus serves as a resource paper for the field.

     Evaluation Summary:

     This manuscript reports the development of a proteo-genomic screening methodology to identify protein-protein interactions between secreted proteins and their cell surface receptors. The authors use a CRISPRa-based approach to overexpress membrane proteins in cells and then use magnetic cell sorting to identify receptors that bind candidate ligands. This approach leads to the identification of several novel interaction pairs that are validated biochemically, including receptor tyrosine phosphatase ligands and other interactions with implications for immune system function. The work is of interest to a wide variety of fields including biochemistry and signaling.

      Evaluation Summary:

      The authors provide a summary of single and double mutants in five self-cleaving ribozymes using next-generation sequencing. They dissect their data in terms of epistasis effects, which provides a new angle to understanding ribozyme function. In principle, this allows conclusions to be drawn on bases involved in pairs and in catalysis that have the potential to be of use to the field, although there is also a series of technical weaknesses that should be addressed.
