      eLife Assessment

      The use of DNA tethers is an important advance for studying how motor proteins respond to load. The authors use a convincing methodology to investigate the detachment and reattachment kinetics of kinesin-1, 2, and 3 motors against loads oriented parallel to the microtubule. As the manuscript stands, the conclusions drawn from the experiments, as well as the overall interpretation of the results, are incompletely supported by the presented data, and the novelty over previous reports appears less clear.

      The mechanistic basis for the potential health benefits of NAD⁺ precursors remains incompletely understood. This manuscript provides a useful assessment of the role of SIRT1 in mediating the effects of NMN in mice fed a high-fat diet. The study addresses a key question, though some of the conclusions appear only partially supported by the presented data.

      The authors identify a novel, conserved link between glycolytic flux and sulfur amino acid metabolism that governs fungal morphological differentiation independently of the cAMP-PKA pathway. This represents an important conceptual advance in understanding metabolic control of development and virulence. While the evidence supporting this connection is compelling, the mechanistic basis of how glycolysis regulates the Met30/Met4 axis requires further experimental clarification.

      This valuable study provides insights into the role of Pten mutations in SHH-medulloblastoma, by using mouse models to resolve the effects of heterozygous vs homozygous mutations on proliferation and cell death throughout tumorigenesis. The experiments presented are convincing, with rigorous quantifications and orthogonal experimentation provided throughout, and the models employing sporadic oncogene induction, rather than EGL-wide genetic modifications, represent an advancement in experimental design. However, the study remains limited, such that the biological conclusions do not extend greatly from those in the extant literature. This could be addressed with additional experimentation focused on cell cycle kinetic changes at early stages, as well as greater characterization of macrophage phenotypes (e.g., microglia vs circulating monocytes). The work will be of interest to medical biologists studying general cancer mechanisms, as the function of Pten may be similar across tumor types.

      The manuscript by Hensley and Yildez studies the mechanical behavior of kinesin under conditions where the z-component of the applied force is minimized. The important study shows that much of the mechanical information gleaned from the traditional "one bead" with attached kinesin approach was probably profoundly influenced by the direction of the applied force. The data are convincing, but in some cases the amount of data collected appears to be smaller than optimal.

      This useful manuscript reports findings indicating that cell cycle progression and cytokinesis both play a role in the transition of early to late neural stem cell fates. The imaging data are solid and mostly support the conclusions. However, experimental details are missing, the method of quantitation could be improved, and orthogonal approaches are needed to confirm the findings, which are based on loss-of-function approaches and are not sufficient to support some of the authors' conclusions. Lastly, there is no investigation of the underlying mechanism linking the cell cycle or cytokinesis to the changes (or lack thereof) of early and late NSC fates.

      The authors used a Bayesian modeling framework to fit behavior and serotonin neuron activity to reward history across multiple timescales. A key goal was to distinguish value coding from other influences, particularly thirst, by comparing model fits across neurons. Although the question and approach are valuable, several limitations of the current manuscript mean that support for the conclusions is incomplete.

      This important study investigates how the nervous system adapts to changes in body mechanics using a tendon transfer surgery that imposes a mismatch between muscle contraction and mechanical action. Using electromyography (EMG) to track muscle activity in two macaque monkeys, the authors conclude that there is a two-phase recovery process that reflects different underlying strategies. However, neither monkey's data includes a full set of EMG and kinematic measurements, and the two datasets are not sufficiently aligned with each other from a behavioural point of view; as a result, the evidence supporting the conclusions is solid but could be improved.

This package is a valuable resource for researchers with computational expertise, implementing a framework for the detection of directed social interactions within a group and an interactive tool for reviewing and correcting behavior detections. However, the strength of evidence that the method is widely applicable remains incomplete, performance on benchmark dyadic datasets is comparable to existing approaches, and performance scores on collective behavioral datasets are low. While the package can analyze behavior in large groups of animals, it only outputs dyadic interactions within these groups and does not account for behaviors where more than two animals may be interacting.

The authors elegantly use 2D template matching to provide solid evidence that Unbend outperforms the previously reported method of Unblur by the same authors. The paper would benefit from the inclusion of a similar analysis for established alternative methods, such as MotionCor2.
