     Evaluation Summary:

     The gut of honeybees is colonized with stable community of bacterial symbionts. The molecular mechanisms involved in this stable associations are poorly understood. Here Schmidt et. al. focused on the identification of bacterial factors required for the colonization of the bee gut symbiont Frischella perrara. They identified a major regulator involved in controlling the expression of multiple colonization factors in F. perrara which include factors that are either required for the induction of a distinct scab phenotype upon gut colonization, or are involved in promoting colonization through adhesin or the production of secondary metabolites. The work is of potential interest for researchers in the field of host-microbe interactions and symbiosis, and for the study of bee health. The valuable integration of different techniques used in this study and rigor of the experiments lead to solid data and justified conclusions.

     Evaluation Summary:

     This paper reports the surprising observation that the general transcription factor TFIIH, but not transcription, is required for chromosome condensation in frog egg extracts. TFIIH may act by facilitating condensin localization and function. This opens up a lot of interesting new questions and lines of research that promise to add significantly to the field of chromosome biology. It will now be interesting to directly test the mechanism of action, and to examine whether this role of TFIIH extends to somatic cells and other animals.

     Evaluation Summary:

     The authors report that upon exposure of yeast cells to paraquat-induced superoxide production, specific mitochondrial DNA genes encoding electron transport chain proteins are deleted to minimize the generation of endogenous superoxide. Reversible loss of mitochondrial DNA as an adaptive response to paraquat stress is an interesting idea. The data presented appear to support the proposed model, but could be further strengthened as alternative interpretations of the described observations are possible.

   • Curated by eLife

     Evaluation Summary:

     This paper presents a novel computational model of metacognition that parameterizes links between sensory evidence and confidence. The proposed model relies on perceptual decision-making to formalize different sources of noise and bias that impact confidence, with the aim of developing metacognitive metrics that are independent of perceptual sensitivity - a continued endeavor in the field. Despite the clear merits of this approach, more evidence is needed to validate the proposed architecture, which is particularly modular, and may therefore impair the generalizability of the proposed mechanisms.

     The manuscript presents a potentially interesting new method to study alternative splicing at the single-cell level in the mouse. With further testing and benchmarking, this method would be of interest to researchers working with single-cell data and/or interested in alternative splicing.

     Evaluation Summary:

     This paper is of interest to scientists and clinicians within the field of muco-obstructive diseases in the airways, such as cystic fibrosis (CF) and chronic obstructive pulmonary disease (COPD). It identifies the sodium-bicarbonate cotransporter SLC4A4 as a key component of the mechanism by which normal airways prevent the formation of sticky mucus and defend theirselves against bacterial and viral infections.

     Evaluation Summary:

     Lövestam et al. report 76 cryo-EM structures of in vitro assembled recombinant tau filaments, including 27 previously unobserved ones. Together with the recent paper from Scheres and Goedert research groups, the structure-based knowledge of amyloid assembly will be boosted several fold. Most importantly, a few in vitro conditions were found to replicate the amyloid structures from both Alzheimer's disease and chronic traumatic encephalopathy. Those findings will open up new avenues to quickly screen compounds that inhibit filament formation under in vitro conditions, as well as the (self-)assembly process of amyloid fibrils.

     Evaluation Summary:

     Zhou et al. provide a robust study on isotopic and metabolic changes of a soil community across a gradient of different land-use types in Sumatra, Indonesia. By mixing community-based analyses of stable isotopes and size-based metabolic measures, they are able to elucidate, for the first time, important links among plants and the soil food web in tropical ecosystems. This study is of importance to tropical biologists, ecosystem ecologists and biodiversity conservationists aiming to understand the impacts of humans on tropical forests.

     Evaluation Summary:

     This is an excellent, innovative and high quality study that reveals an essential role for isoprenoids within the Plasmodium apicoplast, and demonstrates a likely polyprenol synthase that is required for apicoplast biogenesis. This is an important finding for understanding apicoplast and isoprenoid biology in general, and is significant because synthesis of isoprenoids appears to be the only essential role for the apicoplast in asexual intraerythrocytic stages.

      Evaluation Summary:

      Key steps in the evolution of more complex life involve evolutionary transitions in individuality-the origin of new biological entities (i.e., multicellular organisms). This paper presents a novel criterion for measuring when this transition has occurred, via the presence of trade-off breaking adaptations. This work has considerable merit and will be of particular interest for diverse researchers studying transitions in individuality. Some of the author's overarching claims require further clarification.
