Brown adipose tissue (BAT) is key for metabolic balance. Here, the authors show that RAP250 deficiency enhances BAT activity. Under these conditions, BAT-derived neuritin-1 regulates thermogenesis and fat metabolism, showing therapeutic promise for obesity and metabolic disorders.

Brain age gaps (BAGs) highlight deviations from healthy brain aging, yet their biophysical underpinnings in aging and dementia are not well understood. Here, the authors use EEG connectivity and generative modeling across diverse populations to reveal that BAGs are influenced by geography, income, sex and education, with implications for understanding accelerated aging and dementia.

The quark structure of the f₀(980) hadron is still unknown after 50 years of its discovery. Here, the CMS Collaboration reports a measurement of the elliptic flow of the f₀(980) state in proton-lead collisions at a nucleon-nucleon centre-of-mass energy of 8.16 TeV, providing strong evidence that the state is an ordinary meson.

Neural mechanisms underlying the construction of distinct barrel maps, and to what extent they rely on the type of sensory receptors are not fully understood. Here authors show that prenatal mystacial whisker ablation triggers a thalamic mechanism that rescales cortical territories, refining upper lip whisker barrels and enhancing sensory resolution, emphasizing a critical developmental process in sensory mapping.

Alfajaro et al identify that a bat MERS-like coronavirus HKU5 uses ACE2 as a receptor from its natural bat reservoir Pipistrellus abramus and American mink. Structural analyses demonstrate a unique interaction between the HKU5 receptor binding domain and bat ACE2. This highlights the receptor flexibility of merbecoviruses and identifies mink as potential intermediate hosts, informing viral surveillance and countermeasure development.

An analysis of 24,202 critical cases of COVID-19 identifies potentially druggable targets in inflammatory signalling (JAK1), monocyte–macrophage activation and endothelial permeability (PDE4A), immunometabolism (SLC2A5 and AK5), and host factors required for viral entry and replication (TMPRSS2 and RAB2A).

Literature produced inconsistent findings regarding the links between extreme weather events and climate policy support across regions, populations and events. This global study offers a holistic assessment of these relationships and highlights the role of subjective attribution.

Crop wild relatives’ genetic diversity is usually not considered in conservation planning. Here, the authors introduce an approach to identify conservation areas based on evolutionary and threat processes, by developing proxies of genetic differentiation, and including taxa’s habitat preferences.

Investigations in wild bats and non-human primates in Brazil and Costa Rica inform about diverse Morbillivirus ecology in neotropical bats and host jumps, and about zoonotic potential of morbilliviruses in Latin America.

Drug resistance remains a major challenge in cancer treatment. Here, the authors identify Connexin43 as target that enhances BRAF/MEKi efficacy by interfering with DNA repair pathways, overcoming drug resistance. They develop an mRNA therapy that improves efficacy and sensitizes resistant cells.

Trees come in all shapes and size, but what drives this incredible variation in tree form remains poorly understood. Using a global dataset, the authors show that a combination of climate, competition, disturbance and evolutionary history shape the crown architecture of the world’s trees and thereby constrain the 3D structure of woody ecosystems.

An artificial reaction centre has been designed that contains a benzimidazole–phenol model of the Tyr–His relay in photosystem II. It has been seen to mimic both the short internal hydrogen bond of the natural relay, and — using electron paramagnetic resonance —the relaxation behaviour that accompanies proton-coupled electron transfer in photosystem II.

Cell-matrix adhesions may increase or decrease in size in response to tension; however, the factors determining which of these responses predominates remain unclear. Hernández-Varas et al. quantify the plastic relationship between adhesion size and tension and use modelling to explain this behaviour.

The amount of water transported southwards by the Deep Western Boundary Current shows a 26% decline since 2014 in mooring array monitoring data, despite the strength of the Atlantic Meridional Overturning Circulation remaining stable.

Wood density is a key control on tree biomass, and understanding its spatial variation improves estimates of forest carbon stock. Sullivan et al. measure >900 forest plots to quantify wood density and produce high resolution maps of its variation across South American tropical forests.

Analysis of 20 chemical and morphological plant traits at diverse sites across 6 continents shows that the transition from semi-arid to arid zones is associated with an unexpected 88% increase in trait diversity.

Known genetic loci account for only a fraction of the genetic contribution to Alzheimer’s disease. Here, the authors have performed a large genome-wide meta-analysis comprising 409,435 individuals to discover 6 new loci and demonstrate the efficacy of an Alzheimer’s disease polygenic risk score.

What is the state of trust in scientists around the world? To answer this question, the authors surveyed 71,922 respondents in 68 countries and found that trust in scientists is moderately high.

Optical amplifiers based on erbium ions typically require high pump power densities to produce gain. Now, an organic optical amplifier material composed of erbium ions and a zinc-based organic chromophore is demonstrated to reach population inversion using low-power visible light.

The authors report shotgun sequences from airborne environmental DNA samples, identifying local biodiversity and enabling deeper analysis of specific species and genomic regions of interest.

The Hedgehog signalling gradient is established by dynamic signalling filopodia (cytonemes). Here, the authors show that EGF signalling may regulate cytoneme dynamics by maintaining basal plasma membrane levels of the Hedgehog co-receptor Ihog in the wing disc epithelium.
