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.

New findings reveal how terrain influenced Mars’s early surface evolution, allowing regions of stable chemical weathering to develop and permanently trap water and minerals, weakening Mars’s climate feedback and limiting long-term hydrological activity.

Du and Haith show that behaviour can become habitual in two different ways, involving response initiation and response preparation.

Scaling up green hydrogen will be difficult if future projects solely depend on expensive subsidies to overcome competitiveness barriers. Policy makers need to implement supportive policies grounded in realistic expectations, focusing on hydrogen-specific support in sectors where electrification isn’t feasible, while also gradually introducing technology-neutral market mechanisms such as carbon pricing.

Whether multimorbidity accelerates brain Aβ deposition in humans remains largely unknown. Here, the authors demonstrate that higher self-reported multimorbidity burden predicts increased brain Aβ accumulation rates in the ADNI cohort.

Nonselective engagement of GPCR signaling pathways by GPCR-targeting drugs can reduce treatment efficacy and cause side effects. The authors show that signaling selectivity in CB2R can be tuned by reshaping allosteric networks, offering insights for more precise therapies.

Fluorogenic RNA aptamers such as Mango are powerful tools for RNA imaging. An ultrabright RNA-activated fluorophore with improved photophysical performance has now been developed using a structure-informed, fragment-based screening approach. This system was studied using high-resolution crystallography and applied to image RNA in cells.

Fusidic acid inhibits translation by locking EF-G to the bacterial ribosome. Here, the authors use cryo-EM to visualize the transient state where resistance protein FusB mediates rescue by inducing large-scale conformational changes of EF-G.

Green ammonia production could contribute to decarbonization and the decentralization of fertilizer production, but it brings critical challenges and risks. Assessing and addressing these challenges in real time will help advance technology and avoid unintended consequences.

Liver macrophages are a major obstacle to extrahepatic drug delivery. This study identifies the receptor–ligand interactions that they use to capture circulating nanoparticles and leverages this understanding to engineer nanoparticles that escape macrophage uptake.

Structural elucidation of the RNA aptamer 'Spinach' reveals that a new G-quadruplex structure forms the fluorophore-binding site that confers the ability of the RNA to function as a GFP mimic.

Genome-wide analyses identify 30 independent loci associated with obsessive–compulsive disorder, highlighting genetic overlap with other psychiatric disorders and implicating putative effector genes and cell types contributing to its etiology.

A pan-cancer genomic analysis reports the effects of structural variations on chromatin domains (TADs). Most TAD disruptions do not result in appreciable changes in expression of nearby genes.

Tumour endothelial cell macropinocytosis is the dominant mechanism for nanoparticle entry into the tumour. Enhanced nanoparticle tumour accumulation may be due to upregulated macropinocytosis membrane ruffling compared with most healthy tissues.

Green hydrogen is a crucial part of plans to achieve climate targets, yet how quickly supply will scale is unclear. Using a technology diffusion model, Odenweller et al. suggest that even if electrolysis capacity grows as quickly as wind and solar power, green hydrogen supply will suffer from short-term scarcity and long-term uncertainty.
