A global research network monitoring the Amazon for 30 years reports in this study that tree size increased by 3% each decade.

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.

The replication stress response ensures genomic stability throughout DNA duplication. Here, the authors show that VCP/p97 extracts the DNA polymerase α/Primase complex from chromatin, preventing excessive priming in the lagging strand and reducing the activation of the replication stress response.

Olfactomedin-2 is a pleiotropic glycoprotein emerging as a regulator of energy homeostasis via the hypothalamus. The present findings functionally connect adipose-specific OLFM2 to obesity, and highlight its significance in maintaining adipocyte commitment to avoid metabolic disease.

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.

The relative contribution of intrinsic and extrinsic factors to astrocyte heterogeneity is unknown. Using heterotropic transplantation of septal astrocytes with distinct lineage origins, we show that local factors specify their ultimate identities.

Through gene knockout experiments, Sicinski and colleagues reveal a role for cyclin C as a haploinsufficient tumour suppressor in T-cell acute lymphoblastic leukaemia, acting through phosphorylation of intracellular Notch1, mediating its degradation.

Huntington’s disease (HD) is caused by misfolding of mutant Htt protein. The authors find that in HD models, the decreased expression of heat shock transcription factor 1 that usually protects against protein misfolding, is in part caused by elevated CK2α’ kinase and Fbxw7 E3 ligase expression.

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.

Activity-dependent gene expression is thought to involve translocation of Ca²⁺/calmodulin (CaM) to the nucleus. Here, the authors examine a translocation-deficient mutant of γCaMKII, a Ca²⁺/CaM shuttle protein, to show that translocation of Ca²⁺/CaM is required for memory and synaptic plasticity.

The authors analyse tree responses to an extreme heat and drought event across South America to understand long-term climate resistance. While no more sensitive to this than previous lesser events, forests in drier climates showed the greatest impacts and thus vulnerability to climate extremes.

The advantage of living in cities compared with rural areas with respect to height and BMI in children and adolescents has generally become smaller globally from 1990 to 2020, except in sub-Saharan Africa.

The RNA methyltransferase activity of SPOUT1/CENP-32 is crucial for accurate mitotic spindle organization. Here, the authors describe a neurodevelopmental disorder caused by bi-allelic pathogenic SPOUT1 variants with reduced activity and compromised function in spindle organization.

Inventory data from more than 1 million trees across African, Amazonian and Southeast Asian tropical forests suggests that, despite their high diversity, just 1,053 species, representing a consistent ~2.2% of tropical tree species in each region, constitute half of Earth’s 800 billion tropical trees.

Lopez-Otin and colleagues report that NF-κB signalling hyperactivation in progeria syndrome fibroblasts inhibits their reprogramming into iPS cells. Blockade of this pathway or the downstream factor DOTL1 rescues senescence-related phenotypes.

The ability of cancer cells to survive in anchorage-independent conditions correlates with cancer aggressiveness.
