Nitrogen and phosphorus limitations are both key to spatial patterns and temporal trends in primary production. This global analysis indicates that phosphorus limitation on terrestrial primary productivity has become stronger and is increasing more rapidly than nitrogen limitation.

Ecosystems filter environmental variability through internal regulatory mechanisms, resulting in more predictable carbon fluxes than the weather conditions they experience. Here, the authors find that more productive ecosystems exhibit higher temporal complexity in their carbon cycling. This short-term complexity appears to be increasing over time, potentially indicating greater ecosystem responsiveness to environmental stimuli.

Toghani, Gupte et al. identify semaphorin 4A as a cell-extrinsic factor that protects myeloid-biased hematopoietic stem cells from inflammaging, mainly produced by their progeny—neutrophils—and acting via a negative feedback loop.

In a cluster-randomized trial conducted across 70 medical centers in six countries, a 16-week structured educational program for healthcare providers improved adherence to guidelines for rhythm control but not for stroke prevention in individuals with atrial fibrillation.

Lipid concentration in the serum is one of the most important risk factors for coronary artery disease and can be targeted for therapeutic intervention. A genome-wide association study in >100,000 individuals of European ancestry now finds 95 significantly associated loci that also affect lipid traits in non-European populations. Among associated loci are those involved in cholesterol metabolism, known targets of cholesterol-lowering drugs and those that contribute to normal variation in lipid traits and to extreme lipid phenotypes.

Islands of inversions are regions of the nuclear chart where deformed configurations are energetically favoured over spherical ones. Now experiments show that ⁶²Cr assumes different shapes with excitation energy, which is a signature of such islands.

Bottom-up and top-down approaches are used to quantify global nitrous oxide sources and sinks resulting from both natural and anthropogenic sources, revealing a 30% increase in global human-induced emissions between 1980 and 2016.

Kathryn Lunetta and colleagues report a meta-analysis of 22 genome-wide association studies for age at menopause. They identify 13 loci newly associated with age at natural menopause, including several candidate genes with roles in DNA repair and immune function.

Three key axes of variation of ecosystem functional changes and their underlying causes are identified from a dataset of surface gas exchange measurements across major terrestrial biomes and climate zones.

Phosphorus (P) limitation is pervasive in tropical forests. Here the authors analyse the dependence of photosynthesis on leaf N and P in tropical forests, and show that incorporating leaf P constraints in a terrestrial biosphere model enhances its predictive power.

Large classes of metal clusters are expected to have dipole-allowed electronic transitions in the near-infrared, but precise experimental characterization of such low-lying states is lacking. Here, the authors probe cationic cobalt clusters of 4 to 15 atoms using IR photofragmentation spectroscopy with krypton as a messenger atom to show that low-lying electronic excited states are responsible for the size-dependent radiative decay of these highly excited clusters.

A detailed assessment of the techno-economic potential of enhanced rock weathering on croplands identifies national CO₂ removal potentials, costs and engineering challenges if it were to be scaled up to help meet ambitious global CO₂ removal targets.

Springtails are omnipresent soil arthropods, vital for ecosystems. In the first global assessment of springtails, this study shows a 20-fold biomass difference between the tundra and the tropics, with distinct temperature-related patterns for diversity and metabolism that suggest climate change may restructure the functioning of soil biodiversity.

Michael Talkowski and colleagues analyze balanced chromosomal abnormalities in 273 individuals by whole-genome sequencing. Their findings suggest that sequence-level resolution improves prediction of clinical outcomes for balanced rearrangements and provides insight into pathogenic mechanisms such as altered gene regulation due to changes in chromosome topology.

The transcription factor DAF-16/FOXO is a downstream effector of insulin/insulin-like growth factor signaling and plays an important role in stress resistance and longevity. Here, the authors show that DAF-16/FOXO can form a complex with HLH-30/TFEB to synergistically regulate transcription of target genes in response to certain stress stimuli.

Paul Elliott, Martin Tobin, Cornelia van Duijn and colleagues report a genome-wide association study for pulse pressure and mean arterial pressure, identifying six new loci influencing these two traits.

Yeast and cancer cells both favor sugar fermentation in aerobic conditions. Here the authors describe a conserved mechanism from yeast to mammals where the glycolysis intermediate fructose-1,6-bisphosphate binds Cdc25/Sos1 and couples increased glycolytic flux to increased Ras proto-oncoprotein activity.

During homeostasis T_H1 cells activate a cell-intrinsic inflammatory shutdown program and shift to IL-10 production. Chauss et al. find that this T_H1 homeostatic program is dependent on vitamin D signaling and is disrupted in severe COVID-19.

Investigating the evolutionary origins of montane biodiversity by sampling the entire biota from a single mountain, Mount Kinabalu in Borneo, allows for a better understanding not only of the origins of endemism, but also of this biota’s forecasted response to environmental change.

Leena Peltonen and colleagues report a genome-wide association study of cholesterol and triglyceride levels in 16 population-based cohorts across Europe. Six new loci were identified, and overall a genetic risk score improves the screening of high risk groups for dyslipidemia.

Metabolic dysfunction-associated steatohepatitis (MASH), a primary cause of chronic liver disease (CLD), often leads to advanced CLD stages such as cirrhosis. This Roadmap summarizes the current landscape and challenges of MASH-related compensated cirrhosis clinical trials and explores a way forward for future studies.

The treatment of IBD is currently suboptimal. Continuous monitoring of patients with IBD, patient engagement and early treatment adjustments are still difficult hurdles. E-Health could be an efficient tool to improve these aspects, but the current evidence for its use in IBD is poor. An integrated cost-effective e-health system supported by a stable legal framework is eagerly needed.

Care for patients with tuberous sclerosis complex (TSC) should be coordinated by a multidisciplinary team. This Consensus Statement, which involved input from nephrologists, urologists, geneticists, radiologists, interventional radiologists and pathologists as well as patient representatives, provides an overview of TSC-associated kidney manifestations and outlines current recommendations for the management of kidney involvement in TSC.

An updated set of reporting standards for the development, interpretation and evaluation of polygenic risk scores is presented, which should aid the translation of these scores into clinical applications.

A substantial amount of atmospheric carbon taken up on land is transported laterally from upland terrestrial ecosystems to the ocean. A synthesis of the available literature suggests that human activities have significantly increased soil carbon inputs to inland waters, but have only slightly affected carbon delivery to the open ocean.
