     eLife Assessment

     This important study measures how 52 of the 58 human receptor tyrosine kinases move in the membrane of living cells, one molecule at a time, before and after stimulation, and provides a comparative resource for the field. The evidence for these measurements is solid: the raw movies and tracking results are publicly deposited, and openly available code reproduces the analysis of movement states on a representative subset, although the tracking step relies on commercial software. The evidence linking these movement patterns to the regulation of cell growth is incomplete, because it rests on correlations with public datasets the authors did not test experimentally. The work will interest cell biologists and biophysicists who study membrane receptors and signalling.

     eLife Assessment

     This study provides valuable evidence that the metabolically activated proteostasis regulator AA147 preferentially suppresses T helper 17 cell differentiation, implicating nuclear factor erythroid 2-related factor 2 (NRF2), reduced reactive oxygen species (ROS) levels, and proteasome-dependent degradation of RORγt in this effect. The findings are supported by solid evidence from complementary pharmacological, genetic, biochemical, transcriptomic, proteomic, and cellular approaches. However, the precise mechanistic link between NRF2 activation, ROS reduction, and RORγt degradation remains to be fully elucidated.

     This useful study describes a well-designed lightweight head-mounted microscope that uses structured illumination to suppress out-of-focus background fluorescence, potentially enhancing real-time decoding of neuronal activity. However, the evidence for its central performance claims is incomplete: whereas the method shows improvement compared to unprocessed conventional images, typical image processing steps widely used in the field generated similar results, suggesting a limited practical advance.

     eLife Assessment

     This valuable study uses longitudinal single-animal tracking in the Buridan arena to examine recovery of visually guided behavior after optic lobe injury in Drosophila and identifies a potential role for Myc-dependent neural progenitor activation in this process. The evidence is incomplete, as key controls and analyses are lacking to exclude alternative explanations for the behavioral recovery and to firmly establish the requirement for progenitor activation.

     This important study uses multi-session fMRI and multivariate analyses to investigate how interocular suppression affects binocular disparity representations across the human visual cortex. The authors provide convincing evidence that interocular suppression weakens disparity-related information in the dorsal visual stream, particularly in V3A and IPS. The findings further suggest that suppression alters anticorrelated binocular disparity representations and reduces coordinated disparity-related information across dorsal visual areas. Together, these results advance our understanding of how binocular integration and interocular suppression interact and highlight the involvement of higher-level dorsal visual regions in these processes.

     In this useful study, Du and colleagues report a fossil specimen of a swimming flap probably belonging to the radiodont Amplectobelua symbrachiata from a new locality of the early Cambrian Chengjiang Biota. The authors interpret a W-shaped notch as the first evidence of healed injuries on an apex predator of the Cambrian. With this reasonable and solid evidence, the manuscript has potential significance for understanding ecological interactions among high trophic levels in the Cambrian.

     eLife Assessment

     An in vivo imaging medium raises the refractive index of the fluid surrounding cells in the brain, rendering living tissue more accessible to light for in vivo experimentation. This important approach enables imaging neurons more brightly and at greater depth than in untreated tissue. Solid evidence, consisting of both optical and electrophysiological neural activity recordings in brain slices and in living mice, demonstrate a clearing effect, albeit subtle, and not without a significant impact on mice behavior, which limits the use of the proposed method. This work will be of relevance to any optical studies of in vivo tissue.

     This important work substantially advances our understanding of non-synaptic biophysical mechanisms underpinning associative learning. The evidence supporting the conclusions is convincing, with rigorous behavioural assays and state-of-the-art electrophysiology. The work will be of broad interest to neurobiologists and biophysicists.

     eLife Assessment

     This valuable study advances our understanding of how feature expectations influence visual perception and eye movements independently of presaccadic attention. The primary findings - showing that feature expectation and presaccadic attention modulate visual sensitivity through distinct, non-interacting processes - are supported by solid evidence from a carefully controlled factorial design and two psychophysical experiments. However, support for the proposed mechanistic interpretation is incomplete, as the experimental design does not fully distinguish expectation effects from stimulus repetition or separate expectation - related changes in eye-movement timing from stimulus-induced inhibition, and certain aspects of the statistical analysis and perceptual threshold procedures require clarification.

      This useful study shows that loss of Samp1, a protein at the boundary of the cell nucleus, disrupts muscle cell development and is accompanied by changes in gene activity and genome organization. Some of the evidence is solid, but data to support the overall claims is judged to be incomplete. Controlled experiments and mutants to establish whether the changes in organization contribute to impaired development or follow from it would elevate the work. This work will be of interest to those in the genome organization and developmental fields.
