Humanity’s Last Exam, a multi-modal benchmark at the frontier of human knowledge, is designed to be an expert-level closed-ended academic benchmark with broad subject coverage.

Microbial decomposition of plant litter initially increases the molecular diversity of dissolved organic matter, but prolonged microbial recycling diminishes this diversity, highlighting how microbial metabolism influences soil carbon turnover.

South American cordilleran orogenic systems have repeated complex magmatic and deformation histories. Here the authors analyze detrital zircons found in the Amazon deep-sea fan that record mountain-building events and reveal cycles of orogenesis with periods of ~60–90 Myr since the Phanerozoic.

Improved vaccines and antivirals are needed for many enveloped viruses. Here, the authors identify sulfur-based small molecules that disrupt viral membrane properties, inhibiting fusion and entry, and safely inactivate influenza virus. The resulting inactivated influenza vaccine is protective in mice.

Chronic care manages long-term, progressive conditions, while acute care handles short-term ones. Here, authors show chronic conditions account for most of the global health burden, with 68% of DALYs and 93% of YLDs attributed to chronic care needs.

Viral pathogen load in cancer genomes is estimated through analysis of sequencing data from 2,656 tumors across 35 cancer types using multiple pathogen-detection pipelines, identifying viruses in 382 genomic and 68 transcriptome datasets.

Previous studies have disagreed over whether efficient or inefficient network structures should be more effective in promoting group performance. Here, Barkoczi and Galesic demonstrate that which structure is superior depends on the social learning strategy used by individuals in the network.

A global network of researchers was formed to investigate the role of human genetics in SARS-CoV-2 infection and COVID-19 severity; this paper reports 13 genome-wide significant loci and potentially actionable mechanisms in response to infection.

Bacterial genes required for plant colonization are highly host- and organ-specific. An efflux pump detoxifies specific Arabidopsis glucosinolates to protect commensal bacteria from plant chemical defenses during colonization.

DNA origami enables precise nanoscale self-assembly. Authors here show how programmable control of interactions and binding angles yields curved surfaces of diverse geometries, broadening the design space for synthetic nanostructures.

Microglia mediate the early and selective degeneration of corticostriatal synapses and the development of cognitive deficits in presymptomatic Huntington’s disease via the complement cascade.

The phenotype and function of immune cells could change during spaceflight. Here the authors use simulated microgravity, coupled to validation with spaceflight data, to assess whether there are distinct gene expression changes in resting and TLR 7/8 stimulated PBMCs and found conserved changes in IFN signalling, the cytoskeleton, IL-6 and sirtuin signalling.

Scientists disagree about area-based conservation’s role in addressing biodiversity loss. This Perspective examines how conservation scientists, land systems scientists and political ecologists approach these debates differently and argues that environmental data justice frameworks can bridge epistemic divides, helping researchers to develop more effective and equitable conservation interventions.

Whole-genome sequencing, transcriptome-wide association and fine-mapping analyses in over 7,000 individuals with critical COVID-19 are used to identify 16 independent variants that are associated with severe illness in COVID-19.

Analysis of data from multiple instruments reveals a giant exoplanet in orbit around the 0.2-solar-mass star TOI-6894. The existence of this exoplanetary system challenges assumptions about planet formation and it is an excellent target for atmospheric characterization.

cSplotch compares spatial transcriptomics data across ages and regions of mouse colon tissue.

Analysing camera-trap data of 163 mammal species before and after the onset of COVID-19 lockdowns, the authors show that responses to human activity are dependent on the degree to which the landscape is modified by humans, with carnivores being especially sensitive.

McGavern and colleagues identified a CD8⁺ T cell population that expresses GZMK in ʽtau-richʼ brains, where it may play a protective role against neurodegeneration.

Inbreeding depression has been observed in many different species, but in humans a systematic analysis has been difficult so far. Here, analysing more than 1.3 million individuals, the authors show that a genomic inbreeding coefficient (FROH) is associated with disadvantageous outcomes in 32 out of 100 traits tested.

Adipose tissue accommodates large volume changes upon expansion, but the molecular mechanisms involved are not fully understood. Here, Aboy et al. describe CAV1 Y14 phosphorylation as required for appropriate adipocyte caveolae flattening and homeostasis.

Resistance to first line treatment is a major hurdle in cancer treatment, that can be overcome with drug combinations. Here, the authors provide a large drug combination screen across cancer cell lines to benchmark crowdsourced methods and to computationally predict drug synergies.

What is the state of trust in scientists around the world? To answer this question, the authors surveyed 71,922 respondents in 68 countries and found that trust in scientists is moderately high.

MetaGraph enables scalable indexing of large sets of DNA, RNA or protein sequences using annotated de Bruijn graphs.

Topological growth control can produce colloidal rods with specific, adjustable lengths. Using an external magnetic field and metamorphic patterns, authors assemble paramagnetic colloidal spheres into walking bipeds, whose length determines their movement towards or away from an active zone.

Drug delivery implants suffer from diminished release profiles due to fibrous capsule formation over time. Here, the authors use soft robotic actuation to modulate the immune response of the host to maintain drug delivery over the longer-term and to perform controlled release in vivo.

GEOTRACES sampling of deep water from the Atlantic, Pacific and Southern oceans allows an estimate of the amount (tripled in surface waters) and distribution (two-thirds increase in water less than a thousand metres deep) of anthropogenic mercury accumulating in the global ocean.

Spectroscopic measurements confirm that when water is adsorbed on drops of an alkali alloy at low pressure a gold-coloured metallic layer forms as electrons rapidly move from the drop into the water.

African swine fever (ASF) is diminishing pork production in East Asia, especially China, but the global economic costs of ASF are unclear. Mason-D’Croz et al. model the effect of Chinese ASF outbreak scenarios on the global pork market, predicting pork, beef and poultry price increases and a decline in per capita calorie intake in China.

A multiancestry genome-wide association study of chronic alanine aminotransferase elevation identifies candidate risk loci for nonalcoholic fatty liver disease, with replication in external cohorts defined by histology or imaging.

The authors analyzed the whole-exome sequences of over 16,000 individuals and found that very rare variants predicted to disrupt the SETD1A gene confer substantial risk for schizophrenia. Damaging variants in SETD1A were also associated with diverse, severe developmental disorders, providing an important genetic link between schizophrenia and other neurodevelopmental disorders.

Here the authors dissect the developmental and functional relationship between tumor-responsive cytotoxic T cells in the tumor versus the tumor-draining lymph nodes (tdLNs), finding that stem-like T_PEX cells dependent on MYB in the tdLNs are required for CD8⁺ T cell tumor infiltration and ICB responses.

Literature produced inconsistent findings regarding the links between extreme weather events and climate policy support across regions, populations and events. This global study offers a holistic assessment of these relationships and highlights the role of subjective attribution.

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.
