      This valuable study presents findings on the role of the ubiquitin-conjugating enzyme UBE2D/eff in maintaining proteostasis during aging. The evidence supporting the conclusions is solid, although one reviewer had concerns about the readout for protein aggregation and the loss-of-function studies. In the future, mechanistic insights explaining the impact of UBE2D/eff deficiency on the accumulation of poly-ubiquitinated proteins and in shortening lifespan would be interesting. The present study is of broad interest to cell biologists working in aging and age-related diseases.

      The manuscript describes human intracranial neural recordings in the auditory cortex during speech production, showing that the effects of delayed auditory feedback correlate with the degree of underlying speech-induced suppression. This is an important finding, as previous work has suggested that speech suppression and feedback sensitivity often do not co-localize and may be distinct processes, in contrast with findings in non-human primates where there is a strong correlation. The strength of the evidence is convincing, with appropriate experimental methods, data, and analysis.

      This useful study addresses the interesting and challenging problem of how neural networks (including possibly the brain) can optimize performance while multi-tasking. The authors address this problem by introducing an information-theoretic framework that balances the costs of control and of automaticity to achieve a desired level of overall performance. They present detailed analyses of this framework, but overall the manuscript is not easily accessible to a broad audience, and the supporting evidence is currently incomplete (but could be greatly improved with substantial revisions). They use information-theoretic terminology in non-standard ways that are not clearly explained, leading to difficulties in interpreting the framework and comparing it to other computational approaches, and the relationship between their findings and empirical data is not always clear.

      This fundamental study describes patterns of anatomical connectivity between the cortex and the thalamus using magnetic resonance imaging data in humans and non-human primates. The measures are related to numerous other modalities to develop a robust understanding of the organisation of the system. The authors provide convincing evidence that there is a difference between sensory and association cortices in terms of their connectivity with the thalamus, which may have downstream effects on brain function. This work will be of interest to neuroscientists interested in the organization and dynamics of cortico-thalamic circuits.

The authors provide compelling evidence that the summed effects of all invertebrates (with large-sized invertebrates being more active in summer and small-sized invertebrates in winter) on decomposition rates result in similar levels of leaf litter decomposition across seasons. The work will be of broad relevance to ecosystem ecologists interested in soil food webs, and researchers interested in modeling carbon cycles to understand global warming.

      This study presents important findings on the differential activity of noradrenergic and dopaminergic input to dorsal hippocampus CA1 in head-fixed mice traversing a runway in a virtual environment that is familiar or novel. The data are rigorously analysed, and the observed divergence in the dynamics of activity in the dopaminergic and noradrenergic axons is solid. Future studies, using specific manipulations of the two distinct midbrain inputs combined with behavioral testing, are required to strengthen the claim that distinct signals to the hippocampus cause distinct behavioral effects.

      This important study introduces a new cortical circuit model for predictive processing. Simulations effectively illustrate that, with appropriate synaptic plasticity, a canonical layer 2/3 cortical circuit - comprising two classes of interneurons providing subtractive and divisive inhibition - can generate uncertainty-modulated prediction errors by pyramidal neurons. The model is compelling; although it relies on many assumptions and has not yet been compared directly to data, the model does align with empirical observations and yields a range of testable predictions. The study is expected to be of great interest to those involved in cortical and predictive processing research.

      TDP-43 mislocalization is a key feature of some neurodegenerative diseases, but cellular models are lacking. The authors endogenously-tagged TDP-43 with a C-terminal GFP tag in human iPSCs, followed by expression of an intrabody-NES that targeted GFP to the cytosol. They convincingly report physical mislocalization and functional depletion of TDP-43, as measured by microscopy and RNAseq. This method will be valuable to investigators studying the biological consequences of TDP-43 mislocalization and the methodology is in line with the current state-of-the-art.

The findings of this important work are that abnormal ECGs that are associated with higher risk of sudden cardiac death are predicted to have almost no relationship with left ventricular ejection fraction, which is conventionally used as a risk factor for arrhythmia. The conclusions are based on compelling evidence for the need of incorporating additional risk factors for assessing post-myocardial infarction patients.

      The authors analyses describe a novel mechanism by which a retrotransposon-derived LTR may be involved in genomic imprinting and demonstrate imprinting of the ZDBF2 locus in rabbits and Rhesus macaques using allele-specific expression analysis. This imprinting of the ZDBF2 locus correlates with transcription of GPR1-AS orthologs. The accompanying genomic analysis is very well executed allowing for the conclusions reached in the manuscript. The revisions made at the request of the reviewers in this important manuscript strengthen the evidence from the genomic analyses, and as a result, the evidence is now convincing and will be informative to the genomics and developmental biology communities.

While this potentially useful study addresses a significant area of pancreatic cancer research, the lack of evidence demonstrating nuclear localization of K17 in human PDAC and the excessive reliance on a single cell line reduce the significance of the work. Moreover, the weak phenotypes of K17 phosphosite mutants provide incomplete support for the authors' mechanistic model.
