Lineage and organ signals sequentially build organ intrinsic nervous systems
Nature, Published online: 13 May 2026; doi:10.1038/s41586-026-10490-ySystems-level analyses of organ intrinsic nervous systems reveal that these networks are initially configured by lineage-dependent programmes, and their architecture and molecular identity are refined by intra-organ specific local cues.
SNOR promotes translation restart after dormancy
Nature, Published online: 13 May 2026; doi:10.1038/s41586-026-10530-7High-resolution in situ cryo-electron tomography in Schizosaccharomyces pombe identifies SNOR protein, which binds to ribosomes during dormancy induced by glucose depletion, priming them for rapid reactivation of protein synthesis upon glucose repletion.
Mesoscale atomic engineering in a crystal lattice
Nature, Published online: 13 May 2026; doi:10.1038/s41586-026-10431-9Electron-beam control enables deterministic placement of tens of thousands of atomic defects in three-dimensional crystals, creating stable, programmable artificial matter for scalable quantum and nanoscale technologies.
Large-scale discovery, analysis and design of protein energy landscapes
Nature, Published online: 13 May 2026; doi:10.1038/s41586-026-10465-zAn analysis of 5,778 domains 28–64 amino acids in length reveals hidden variation in conformational fluctuations, even between sequences sharing the same fold and global folding stability.
Sleep chart of biological ageing clocks in middle and late life
Nature, Published online: 13 May 2026; doi:10.1038/s41586-026-10524-5A cross-organ, multi-omics U-shaped relationship between sleep duration and biological ageing clocks highlights the potential of sleep optimization to promote healthy ageing, lower disease risk and extend longevity.
Obesity rise plateaus in developed nations and accelerates in developing nations
Nature, Published online: 13 May 2026; doi:10.1038/s41586-026-10383-0Global analysis of obesity trends from 1980 to 2024 in 200 countries and territories using data from 4,050 population-based studies reveals that framing obesity as a single global epidemic masks the highly varied dynamics across countries and age groups.
A synaptic locus of song learning
Nature, Published online: 13 May 2026; doi:10.1038/s41586-026-10510-xCombining a computational framework and optogenetic and chemogenetic manipulations within and downstream of the cortico-basal ganglia circuit identifies the specific cortico-basal ganglia synapses that drive the acquisition and expression of rapid vocal changes during juvenile song learning.
White matter micro- and macrostructure brain charts for the human lifespan
Nature, Published online: 13 May 2026; doi:10.1038/s41586-026-10454-2Integration of data representing 35,120 brain scans from diverse global studies enables construction of reference charts that define normative microstructural and macrostructural properties across the human lifespan for research and clinical diagnosis.
Street sellers and private physicians fuel antibiotic overuse
Nature, Published online: 13 May 2026; doi:10.1038/d41586-026-01374-2Limited access to medical professionals and irresponsible prescribing practices are contributing to antimicrobial resistance in low-resource settings.
Old antibiotics are being revived to fight new threats
Nature, Published online: 13 May 2026; doi:10.1038/d41586-026-01379-xThe last antimicrobial peptide was developed decades ago. Now, drug-resistant bacteria are forcing scientists to take a fresh look at this class of antibiotic.
Fast and furious: the gaseous outflows of quasars in the early Universe were extreme
Nature, Published online: 13 May 2026; doi:10.1038/d41586-026-01485-wObservations from the James Webb Space Telescope reveal that extremely fast, galaxy-scale outflows from luminous objects called quasars were much more frequent, and on average more powerful, about one billion years after the Big Bang than at later cosmic epochs. These outflows could easily escape their host galaxies and regulate the evolution of early massive galaxies.
Growth charts reveal how the brain’s ‘communication highways’ change throughout life
Nature, Published online: 13 May 2026; doi:10.1038/d41586-026-01318-wStudies of white matter — the tissue used for communication between brain regions — have revealed substantial changes in people with neurological diseases and disorders. The creation of white-matter brain charts enables individual deviations from the typical structure to be assessed using magnetic resonance imaging (MRI) brain scans.
Can AI tools assess coding assignments?
Nature, Published online: 13 May 2026; doi:10.1038/d41586-026-01139-xYulu Hou and her partner experimented with using ChatGPT to automate marking of undergraduate assignments. Here’s what they learnt.
