Clonal or isogenic model organisms allow for controlled replication, but their isolation from natural systems compromises their relevance for ecology and evolution research. However, a substantial number of vertebrate species reproduce clonally in nature and are an underused resource.

Managing power exhaust in fusion reactors is a key challenge, especially in compact designs for cost-effective commercial energy. This study shows how alternative divertor configurations improve exhaust control, enhance stability, absorb transients and enable independent plasma regulation.

M. Valentini et al. study superconducting quantum interference devices (SQUIDs) where the weak link of the Josephson junctions is a germanium 2D hole gas. They report signatures of the tunneling of pairs of Cooper pairs. For a particular microwave drive power, they observe a 100% efficient superconducting diode effect.

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.

An extreme Einstein ring ~10,000 times as bright as the Milky Way in the infrared is studied with VLT/ERIS and ALMA, and the authors find that the lensed galaxy is a starburst with a fast-rotating disk, rather than being driven by a major merger.

The full extent of the genetic basis for hearing impairment is unknown. Here, as part of the International Mouse Phenotyping Consortium, the authors perform a hearing loss screen in 3006 mouse knockout strains and identify 52 new candidate genes for genetic hearing loss.

The genetic basis of metabolic diseases is incompletely understood. Here, by high-throughput phenotyping of 2,016 knockout mouse strains, Rozman and colleagues identify candidate metabolic genes, many of which are associated with unexplored regulatory gene networks and metabolic traits in human GWAS.

A gatemon is a transmon-type superconducting qubit made using a hybrid superconductor-semiconductor approach enabling tunability with electric gates. Here the authors demonstrate a gatemon qubit in planar germanium, which is anticipated to have various advantages.

This study finds that West African ecosystems are generally more productive than equivalent ecosystems in Amazonia. It also suggests that a semi-deciduous forest site in Ghana is the world’s most productive forest measured to date.

In a multicenter research program coordinated by the International Mouse Phenotyping Consortium, Spielmann et al. analyze the cardiac function and structure in ~4,000 monogenic mutant mice and identify 705 mouse genes involved in cardiac function, 75% of which have not been previously linked to cardiac heritable disease in humans. Using the UK Biobank human data, the authors validate the link between cardiovascular disease and some of the newly identified genes to illustrate the resource value and potential of their mutant mouse collection.

Damian Smedley and colleagues report the phenotypic characterization of the first 3,328 genes by the International Mouse Phenotyping Consortium. They develop new mouse models based on genes known to be associated with human mendelian diseases and identify potential disease-associated genes with little or no previous functional annotation.

GRAPE is a software resource for graph learning and embedding that is orders of magnitude faster than existing state-of-the-art libraries, making large-graph analysis feasible in a wide range of real-world applications.

Pregnancy-associated acute kidney injury is a risk factor for maternal and fetal morbidity and mortality and a driver of health inequity worldwide. This Consensus Statement from the Acute Disease Quality Initiative provides recommendations on the causes, diagnosis, management and follow-up of pregnancy-associated acute kidney injury.

Identification and characterization, using a comprehensive embryonic phenotyping pipeline, of 410 lethal alleles during the generation of the first 1,751 of 5,000 unique gene knockouts produced by the International Mouse Phenotyping Consortium.

Discovery of causal variants for monogenic disorders has been facilitated by whole exome and genome sequencing, but does not provide a diagnosis for all patients. Here, the authors propose a Full Spectrum of Intolerance to Loss-of-Function (FUSIL) categorization that integrates gene essentiality information to aid disease gene discovery.

Despite technological advances, chromosome-level assemblies of mammalian genomes are still rare. Here, the authors use PacBio, Chicago and Hi-C approaches to generate a highly contiguous and partially-phased genome assembly for the water buffalo, Bubalus bubalis

Rhombohedral tetralayer graphene aligned to a hexagonal boron nitride substrate hosts gate-tunable superconductivity and quantized anomalous Hall states, and thermodynamic compressibility measurements further show a fractional Chern insulator at zero magnetic field, paving the way for new hybrid interfaces between superconductors and topological edge states.

European forests are intensively exploited for wood products, yet they are also a potential sink for carbon. European forest inventories combined with timber harvest statistics from sixteen European countries show that between 1950 and 2000 forest biomass increased faster than the amount of timber harvests. Silviculture, which has developed over the past 50 years, can efficiently sequester carbon on timescales of decades, while maintaining forests that meet the demand for wood.

Power exhaust is one of the biggest challenges stopping fusion energy. This article shows experimental evidence for strategically shaping the power exhaust region as a solution to this challenge, utilising physics understanding to strike a balance between engineering complexity and power exhaust benefits, consistent with reduced models and simulations.

The International Mouse Phenotyping Consortium reports the generation of new mouse mutant strains for more than 5,000 genes, including 2,850 novel null, 2,987 novel conditional-ready and 4,433 novel reporter alleles.

The emergence of individualized medicine has spurred the need for the development of clinical decision-support systems (CDSSs) based on prediction models of treatment outcome. In radiation oncology, CDSSs combine clinical, imaging and molecular factors to achieve the highest accuracy to predict tumour response. Here, the authors provide an overview of these factors—including survival, recurrence patterns and toxicity—and discuss the methodology behind the multistage development of CDSSs.

Carbon dioxide uptake by the terrestrial biosphere has the potential to mitigate fossil fuel emissions. Comprehensive estimates of Europe's greenhouse-gas balance suggest that any uptake of carbon dioxide by the terrestrial biosphere is offset by methane and nitrous oxide emissions.

Bret Moore et al. from the International Mouse Phenotyping Consortium report the identification of 347 mouse genes that influence ocular phenotypes when knocked out. 75% of the identified genes have not previously been associated with any ocular pathology.
