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.

In multiple sclerosis, smoldering inflammation contributes to clinical progression. Using multi-omics data, here the authors link chronic inflammation to senescence-like processes and cellular network changes, suggesting a potential therapeutic target.

In targeted protein degradation, a degrader molecule brings a neosubstrate protein proximal to a hijacked E3 ligase for its ubiquitination. Here, pseudo-natural products derived from (−)-myrtanol—iDegs—are identified to inhibit and induce degradation of the immunomodulatory enzyme indoleamine-2,3-dioxygenase 1 (IDO1) by a distinct mechanism. iDegs prime apo-IDO1 ubiquitination and subsequent degradation using its native proteolytic pathway.

Ramaglia and colleagues show that aberrant formation of B cell-rich lymphoid structures in the brain meninges is associated with high CXCL13:BAFF ratios. Inhibiting the kinase BTK reduces the lymphotoxin signaling needed to sustain such structures, lowers CXCL13:BAFF ratios and reduces cortical tissue injury.

In patients with advanced cancer, the development of brain metastasis (BM) often signals a worsening prognosis with limited therapeutic options. Here, the authors assemble a large, open-source neuroimaging dataset of BM and perform spatial and morphological analysis which they use to develop a framework for function-sparing brain radiotherapy design.

A previously unsampled deep lineage in central Argentina was discovered that had distinctive genetic drift by 8,500 bp and persisted as the main Native American ancestry component in the region up to the present day.

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.

Archaeogenetic study of ancient DNA from medieval northwestern Europeans reveals substantial increase of continental northern European ancestry in Britain, suggesting mass migration across the North Sea during the Early Middle Ages.

Genome-wide data from 400 individuals indicate that the initial spread of the Beaker archaeological complex between Iberia and central Europe was propelled by cultural diffusion, but that its spread into Britain involved a large-scale migration that permanently replaced about ninety per cent of the ancestry in the previously resident population.

Genome-wide ancient DNA data from individuals from the Middle Bronze Age to Iron Age documents large-scale movement of people from the European continent between 1300 and 800 bc that was probably responsible for spreading early Celtic languages to Britain.

Analysis of DNA from ancient individuals of the Near East documents the extreme substructure among the populations which transitioned to farming, a structure that was maintained throughout the transition from hunter–gatherer to farmer but that broke down over the next five thousand years.

Genome-wide sequencing of 180 ancient individuals shows a continuous gradient of ancestry in Early-to-Mid-Holocene hunter-gatherers from the Baltic to the Transbaikal region and distinct contemporaneous groups in Northeast Siberia, and provides insights into the origins of modern Uralic and Yeniseian speakers.

Wood density is an important plant trait. Data from 1.1 million forest inventory plots and 10,703 tree species show a latitudinal gradient in wood density, with temperature and soil moisture explaining variation at the global scale and disturbance also having a role at the local level.

Genome-wide ancient DNA data from 225 individuals who lived in southeastern Europe between 12000 and 500 bc reveals that the region acted as a genetic crossroads before and after the arrival of farming.

An investigation using various methods reports an association between adeno-associated virus 2 and paediatric hepatitis of unknown aetiology.

The history of human populations in the islands of the central and western Mediterranean is poorly understood. Here, the authors generate ancient-DNA data from the Balearic Islands, Sicily and Sardinia, and estimate the level and timing of steppe pastoralist, Iranian and North African ancestries in these populations.

At equilibrium, the ferroelectric polarization is proportional to the strain. At ultrafast timescales, an above-bandgap laser excitation decouples strain and polarization, which, out of equilibrium, is mainly determined by the photoexcited electrons.

Species synchrony is considered a major mechanism of biodiversity–ecosystem stability relationships. Here, by combining theory, modelling and empirical work, the authors show that with time series length species synchrony decreases and its relationship with diversity switches from positive to negative.

This flagship study from the European Solve-Rare Diseases Consortium presents a diagnostic framework including bioinformatic analysis of clinical, pedigree and genomic data coupled with expert panel review, leading to 500 new diagnoses in a cohort of 6,000 families with suspected rare diseases.

Analysis of ancient genomic data of 51 humans from Eurasia dating from 45,000 to 7,000 years ago provides insight into the population history of pre-Neolithic Europe and support for recurring migration and population turnover in Europe during this period.

Genome-wide association analyses identify 30 risk loci for IgA nephropathy. Functional annotations of putative causal genes converge on inflammatory signaling pathways and cytokine ligand–receptor pairs, prioritizing potential new drug targets.

Excessive complement C3 causes synaptic stripping and neurodegeneration. Here, the authors used the experimental autoimmune encephalomyelitis (EAE) model of multiple sclerosis and single-cell RNA sequencing to show that C3 expression defines disease-associated reactive glia. C3 deletion abrogated these pro-inflammatory glia and protected neurons.

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.

Ancient DNA reveals genetic differences between stone-tool users and people associated with ceramic technology in the Caribbean and provides substantially lower estimates of population sizes in the region before European contact.

Gelabert et al. examine genomic and archaeological data from Europe’s earliest farming communities in Central Europe (5500–5000 bce). They find differentiated genetic networks but no evidence of unequal access to resources linked to sex or kin.

Goede et al. combined multiple modalities to define a common tremor network across disorders. This finding may help optimize deep brain stimulation and guide future noninvasive therapies.

Little is known about the recent population history or the effects of endogamy on the Pakistani population. Here the authors examine the impact of the biraderi social stratification system on the population structure of individuals of British Pakistani ancestry in the Born in Bradford cohort.

Different functional variants in ADH1B (and elsewhere) in Europeans and Africans strongly affect risk for alcohol dependence. Dependence only partly genetically correlates with consumption, with strong correlations to other psychiatric disorders.

Studies of cell heterogeneity in white matter in primates have been limited to date. Here the authors describe a marmoset brain cell atlas that bridges rodent and human data, revealing strong gray-white matter glial segregation.

Delimiting populations is crucial for conserving threatened species. Using genome-wide data from the whole of Antarctica, Cristofari et al.show that Emperor penguins are organised into a single global population that have shared demography since the late Quarternary.

Researchers create high ionization states, up to Xe³⁶⁺, using 1.5 keV free-electron laser pulses. The higher than expected ionization may be due to transient resonance-enhanced absorption and the effect may play an important role in interactions of intense X-rays with high-Z elements and radiation damage.
