The pet trade puts reptiles and amphibians at risk: close legal gaps now

Nature, Published online: 14 September 2026; doi:10.1038/d41586-026-02852-3

Patchy legislation means that animals are routinely taken from their natural habitats and sold in other countries. Fresh national and international measures could help to stop this exploitation.

Breaking timescales with generative sampling of conformational transitions

Nature, Published online: 09 September 2026; doi:10.1038/s41586-026-11025-1

A generative committor-guided path-sampling framework reconstructs rare biomolecular transition pathways and reveals the underlying thermodynamics and kinetics without using predefined collective variables or brute-force sampling, at an acceptable computational cost.

Within-family effect of ancestry on complex traits in a Mexican population

Nature, Published online: 09 September 2026; doi:10.1038/s41586-026-11039-9

This study uses a within-family design to identify significant ancestry differences in complex traits such as height and type 2 diabetes in a genetically diverse population from Mexico City.

Neocortical long-range inhibition promotes cortical synchrony and sleep

Nature, Published online: 09 September 2026; doi:10.1038/s41586-026-10876-y

In mice, a sparse population of sleep-active long-range inhibitory neurons in the neocortex promote widespread cortical synchronization and sleep, revealing a cortical mechanism that contributes to the regulation of sleep.

An operational perturbation proteomics-based virtual cell model

Nature, Published online: 09 September 2026; doi:10.1038/s41586-026-11001-9

Temporal protein-abundance measurements from systematically perturbed breast cancer cell lines were generated to develop ProteinTalks, a virtual cell model that functions as an operational tool for diverse drug discovery tasks.

PLA2G2D in tumour-draining lymph nodes regulates anti-tumour immunity

Nature, Published online: 09 September 2026; doi:10.1038/s41586-026-10954-1

A specific population of macrophages that express high levels of the enzyme PLA2G2D in tumour-draining lymph nodes is associated with poor prognosis in patients, and inhibiting PLA2G2D improves anti-tumour immunity in mouse models.

Foaming photopolymers as a high-resolution biomimetic printing platform

Nature, Published online: 09 September 2026; doi:10.1038/s41586-026-10968-9

Deep-foam photolithography uses light-controlled polymer foaming to create high-resolution, multifunctional microstructures with tunable optical, wetting and fluid-handling properties for advanced manufacturing applications.

Advancing conflict research and response through satellite-derived data

Nature, Published online: 09 September 2026; doi:10.1038/s41586-026-11004-6

Integrating satellite-derived war-damage data with text-based fatality records through improvement, enrichment and fusion mitigates limitations inherent in each source, revealing complex violence dynamics beyond fatality-centric paradigms, as case studies from Ukraine and Myanmar illustrate.
