Maha Farhat, Megan Murray and colleagues report whole-genome sequencing of 116 Mycobacterium tuberculosis strains selected to be representative of both global diversity and drug resistance. The authors develop a new method to search for resistance markers in microbial genomes based on reconstructing a genome-wide phylogeny and identifying regions showing convergent evolution, and they use this method to identify 39 new candidate drug resistance regions in the M. tuberculosis genome.

A high-bandwidth neuromotor interface offers performant out-of-the-box generalization across people.

Whole-genome sequencing, transcriptome-wide association and fine-mapping analyses in over 7,000 individuals with critical COVID-19 are used to identify 16 independent variants that are associated with severe illness in COVID-19.

Olfactory perception of food-derived odors influences feeding behavior, but the underlying neural pathways remain unclear. Here, the authors show that prolonged exposure to food odor suppresses food intake and body weight gain by activating an olfactory bulb–hypothalamus circuit.

The homeostasis of myelin in the central nervous system is highly regulated, but the underlying mechanisms are unclear. Here, the authors show that the FBXW7 protein has a role in constraining myelin growth in the developing and adult central nervous system, preventing the accumulation of myelin abnormalities. FBXW7 acts in part through targeting the MYRF transcription factor for degradation.

Meta-analyses in up to 1.3 million individuals identify 87 rare-variant associations with blood pressure traits. On average, rare variants exhibit effects ~8 times larger than the mean effects of common variants and implicate candidate causal genes at associated regions.

A sound source localization system reveals behavior-dependent vocal emission and thereby unmasks functions of social vocalization.

A survey of sharks and rays on coral reefs within 66 marine protected areas across 36 countries showcases that the conservation benefits of full MPA protection to sharks almost double when accompanied by effective fisheries management.

The AAA protein spastin is needed for cell division and organelle transport. Testing spastin constructs with engineered mutations resulted in the identification of a chemical probe to analyze spastin-specific functions in cells.

Pumas are experiencing increased isolation as human persecution and habitat loss fragment the populations of this once widespread species. Here, the authors estimate the genomic consequences of this isolation by analyzing the genomes of ten pumas from across North and South America.

A transancestral exome-wide association study for body-fat distribution identifies protein-coding variants that are significantly associated with waist-to-hip ratio adjusted for body mass index.

Analysis of exomes and transcriptomes from 100 African American patients with acute myeloid leukemia identifies ancestry-related variation in mutation profiles and survival. Refined risk classification suggests clinical relevance of these ancestry-associated differences.

Shwachman-Diamond Syndrome (SDS) is an inherited ribosome assembly disorder that increases the risk for haematopoietic malignancies. Here, the authors analysed clonal selection and evolution in SDS by sequencing patient-derived haematopoietic stem/progenitor cell colonies and exploring the function of key drivers in model organisms.

Zymoseptoria tritici is an important fungal pathogen of wheat which has spread globally. Here, the authors perform genomic analyses on a collection of ~1100 Z. tritici samples from 42 countries to describe its global spread and elucidate mechanisms of adaptation to different environmental conditions.

Trans-ethnic analyses of exome array data identify new risk loci for type 2 diabetes. Fine-mapping analyses using genome-wide association data show that the index coding variants represent the likely causal variants at only a subset of these loci.

Data from over 700,000 individuals reveal the identity of 83 sequence variants that affect human height, implicating new candidate genes and pathways as being involved in growth.

Exome-wide analysis identifies rare and low-frequency coding variants associated with body mass index. Gene-based meta-analysis and functional studies implicate 13 genes, eight of which are novel, and neuronal pathways as factors in human obesity.

Intraspecies response to climate change is expected to align with genetic affinity. Using the American pika as a case study suggests that divisions of species distributions best explain intraspecific heterogeneity in climate relationships.

We leverage advances in integrated photonics to generate low-noise microwaves with an optical frequency division architecture that can be low power and chip integrated.

Analyses of the proportions of individuals who have completed key levels of schooling across all low- and middle-income countries from 2000 to 2017 reveal inequalities across countries as well as within populations.

Evan Eichler and colleagues present a detailed characterization of the chromosome 15q13.3 microdeletion region. They identify complex structural polymorphisms and find that the rearrangement breakpoints cluster in palindromic GOLGA8 core duplicons, providing evidence that this repeat and its palindromic architecture underlie the evolutionary and disease-related instability of this region.

Segmental duplications in the genome are regions with the potential for the evolution of phenotypic novelties, but their cataloguing has been technically difficult. Here, the evolution and function of human duplications is characterized.

Cities affect biological evolution, but traditionally researchers focus on the biophysical influence of urban environments. Instead, this Review explores how the social processes of religion, politics and war drive wildlife evolution by shaping urban conditions.

This study reports that flavivirus transmission by mosquitoes to mice is increased if mosquitoes feed subsequently on non-infectious blood, possibly because feeding causes microperforations in the gut. Modelling shows this could explain how A. aegypti can sustain an explosive epidemic such as Zika virus despite its perceived poor vector competence.
