Analysis combining multiple global tree databases reveals that whether a location is invaded by non-native tree species depends on anthropogenic factors, but the severity of the invasion depends on the native species diversity.

Species’ traits and environmental conditions determine the abundance of tree species across the globe. Here, the authors find that dominant tree species are taller and have softer wood compared to rare species and that these trait differences are more strongly associated with temperature than water availability.

Examining drivers of the latitudinal biodiversity gradient in a global database of local tree species richness, the authors show that co-limitation by multiple environmental and anthropogenic factors causes steeper increases in richness with latitude in tropical versus temperate and boreal zones.

The oxygen evolution reaction proceeds over a surface that undergoes (frustrated) phase transitions to accommodate bias-dependent excess charge. Now it has been shown that this excess charge is intimately linked to the interfacial solvation of ions and the pre-organization of the transition state, providing insight into intrinsic catalyst activities.

Polygenic risk scores for Alzheimer’s disease derived from individuals of European ancestry can show improved performance in multiancestry settings after incorporating genome-wide association summary statistics from diverse populations.

Here, the authors show that comparing patients-matched glioma-initiating cells with neural stem cells enables the discovery of patient-specific mechanisms of disease and the identification of effective drugs

Targeted nanodrug delivery is crucial to treat respiratory diseases, but profiling the delivery and dynamics of nanoparticles (NPs) within the lung is a challenging task. Here, the authors present LungVis 1.0, an AI-driven 3D imaging ecosystem to profile inhaled substances in distinct lung regions while uncovering the role of tissue-resident macrophages in the fate of NPs.

The stress-induced martensitic transformation in shape-memory alloys shows a strong size-effect on the critical stress for superelasticity.

CRISPR/Cas9 technology has been used for genome engineering in vivo. Here, the authors use a transfection technique to deliver multiple guide RNAs to the pancreas of adult mice, allowing genetic screening and chromosome engineering in pancreatic cancer.

Molecular networking connects molecules based on their fragment ion mass spectra (MS²), but may leave adduct species from the same molecular family separate. To address this issue, the authors develop a networking approach that fuses MS¹- and MS²-based networks and integrate it into the GNPS environment.

Applying the concept of ecosystem energetics to a grassland biodiversity experiment, the authors show that the storage and flow of energy across the whole trophic network, both above- and belowground, becomes more efficient as plant diversity increases.

Nielsen et al. show that granulin is secreted by metastasis-associated macrophages to promote pancreatic cancer metastasis. Granulin activates hepatic stellate cells, which secrete periostin, thereby resulting in a fibrotic, pro-metastatic liver milieu.

Research on biodiversity–ecosystem functioning relationships tends to focus on single trophic groups. This analysis of two biodiversity experiments, representing forests and grasslands, shows that plant diversity promotes ecosystem multifunctionality not only directly, but also by enhancing the diversity of other trophic levels.

Induction of cardiac contractility, although desirable for restoring heart function, often has long-term detrimental effects. From studies on RKIP, an upstream regulator of β-adrenergic receptor signaling, Schmid et al. show that cardiac contractility in mice can be increased in a well-tolerated manner through the balanced activation of the β1 and β2 subtypes of the adrenergic receptor.

The involvement of cell death pathways in the early stage of pancreatic ductal adenocarcinoma (PDAC) development, especially KRAS-dependent acinar-to-ductal metaplasia (ADM), remains to be investigated. Here, the authors find that TAK1 mediates cell survival during ADM transdifferentiation through suppression of apoptosis and necroptosis, which could be targeted for prevention and treatment of PDAC.

Species-rich plant communities often have higher productivity than monocultures. Here, the authors analyse biodiversity-ecosystem functioning experiments in grasslands and forests and find that the biodiversity effects on community productivity strengthen over time thanks to shifts in contributions of species with different resource acquisition traits.

Although chromatin remodelers have been shown to align nucleosome arrays to barriers and to generate spacing regularity among nucleosomes within arrays, it has remained unclear how the distance to barrier and the spacing length are determined in absolute terms. Here, the authors reveal that remodelers contain a ‘ruler’ element that sets remodeler-specific alignment and spacing distances when generating nucleosome arrays.
