Climate change can alter when and how animals grow, breed, and migrate, but it is unclear whether this allows populations to persist. This global study shows that shifts in seasonal timing are key to helping vertebrate species maintain population growth under global warming.

Kinematic measurements of the Perseus galaxy cluster reveal two drivers of gas motions: a small-scale driver in the inner core associated with black-hole feedback and a large-scale driver in the outer core powered by mergers.

Five-year survival data and biomarker analysis of the PRADO extension cohort of the phase 2 OpACIN-neo trial, in which patients with high-risk stage III melanoma received neoadjuvant ipilimumab and nivolumab and underwent pathologic response-directed surgery and adjuvant therapy, show 71% event-free survival and 88% overall survival, with tumor mutational burden, IFNγ signature and PD-L1 expression associated with favorable outcomes.

Nagahata, Kato and Yamada et al. provide cryo-electron microscopy structures of four phylogenetically diverse RNA-guided nucleases—HfmIscB, TbaIscB, YnpsCas9 and NbaCas9—each in complex with its guide RNA and target DNA, providing insights into CRISPR–Cas9 evolution.

Genomic analyses of DNA from modern individuals show that, about 800 years ago, pre-European contact occurred between Polynesian individuals and Native American individuals from near present-day Colombia, while remote Pacific islands were still being settled.

The distinct architecture of the Escherichia coli membrane transporter LetA mediates lipid trafficking across the bacterial envelope in partnership with the tunnel-like complex LetB.

A cortical premotor network in HVC, once initiated, can sustain and regulate the sequential production of zebra finch song syllables without major extrinsic inputs.

It has been proposed that language meaning is represented throughout the cerebral cortex in a distributed ‘semantic system’, but little is known about the details of this network; here, voxel-wise modelling of functional MRI data collected while subjects listened to natural stories is used to create a detailed atlas that maps representations of word meaning in the human brain.

Understanding collective behaviour is an important aspect of managing the pandemic response. Here the authors show in a large global study that participants that reported identifying more strongly with their nation reported greater engagement in public health behaviours and support for public health policies in the context of the pandemic.

The highest-quality JWST spectra reveal that little red dots are young supermassive black holes shrouded in dense cocoons of ionized gas, where electron scattering, not Doppler motions, broadens their spectral lines.

A national classification system of wetland hydrologic connectivity to streams, which could be applied globally, demonstrates and advances current understanding of how wetland connectivity affects surface water quality.

The electronic behaviour of complex oxides such as LaNiO₃ depends on many intrinsic and extrinsic factors, making it challenging to identify microscopic mechanisms. Here the authors demonstrate the influence of oxygen vacancies on the thickness-dependent metal-insulator transition of LaNiO₃ films.

Melting from the Greenland Ice Sheet triggers land uplift beneath the ice sheet and changes to Earth’s gravitational field and rotation axis, a process called Glacial Isostatic Adjustment. Lewright et al. find that this process will lead to a local sea level fall along Greenland’s coast over this century.
