  This important study advances our understanding of population-level immune responses to influenza in both children and adults. The strength of the evidence supporting the conclusions is compelling, with high-throughput profiling assays and mathematical modeling. The work will be of interest to immunologists, virologists, vaccine developers, and those working on mathematical modeling of infectious diseases.

  eLife Assessment

  This study presents a valuable assessment of increased similarity in visual appearance combined with an increased chemical difference between two butterfly species in sympatry compared with differences between three populations of one of the two species in allopatry. While the evidence is solid, its interpretation in terms of evolutionary responses to shared predators (visual signals) and avoiding between-species mating (chemical signals) is overstated due to the lack of direct experimental evidence.

  Using several hundreds of samples and cutting-edge genomic methods, including BioNano, PacBio, HiFi, and advanced bioinformatic pipelines, the authors identify six large chromosomal inversions segregating in over 100 species of Lake Malawi cichlids. This important study provides compelling evidence for the presence of these six inversions, their differential distribution among populations, and the association of chromosome 10 inversion with a sex-determination locus. This work also provides a starting point for further investigating the role of these inversions with respect to local adaptation, speciation, sex determination, hybridization, and ILS in cichlids, which represent ~5% of the extant vertebrate species and are one of the most prominent examples of adaptive radiations.

  This study reveals the important role of upstream open reading frames (uORFs) in limiting the translational variability of downstream coding sequences. Through a combination of computational simulations, comparative analyses of translation efficiency across different developmental stages in two closely related Drosophila species, and manipulative, experimental validation of translation buffering by an uORF for a gene, the authors provide convincing evidence supporting their conclusions. This work will be of broad interest to molecular biologists and geneticists.

  eLife Assessment

  This important study provides evidence of a deeply conserved role for the gene Mirror in providing positional identity in the posterior part of butterfly and fly wings, despite increased morphological complexity of butterfly wings. The findings are solid for the field of evo-devo. However, the tools in butterflies are more limited than in Drosophila and it is more difficult to determine which specific cells are mutant and whether the effect of mutation is cell-intrinsic. The work will be of interest to evolutionary and developmental biologists working on insect wing evolution and the evolution of patterning more generally.

  eLife Assessment

  Combining experiments in microfluidic devices and computer simulation, this study provides a valuable analysis of the relevant parameters that determine the motility of (multicellular) magnetotactic bacteria in sediment-like environments. The study presents convincing evidence that there is an optimum in the biological parameters for motile life under such conditions.
