The temperature-sensitivity of soil dissolved organic carbon (DOC) export is widely debated but limited by the duration of observations. New data from environmental archives supports a pronounced sensitivity between soil DOC leaching and warming.

In this study, the authors present optimization and efficacy testing of apolipoprotein-based lipid nanoparticles for delivering various nucleic acid therapeutics in vivo to immune cells and their progenitors in the bone marrow.

Combining a low-coherence source with silicon nitride ring resonators featuring normal group velocity dispersion enables electrically pumped, high-power microcombs, providing on-chip power up to 158 mW and high-coherence comb lines with linewidths as narrow as 200 kHz.

Polygenic risk scores can help identify individuals at higher risk of type 2 diabetes. Here, the authors characterise a multi-ancestry score across nearly 900,000 people, showing that its predictive value depends on demographic and clinical context and extends to related traits and complications.

When the cracks begin to show.

The effects of pesticides on individual species could propagate into additional community-wide and ecosystem-level effects. Here the authors use a mesocosm experiment to test how a diverse array of herbicides and insecticides disrupt aquatic community structure and ecosystem function.

Alfajaro et al identify that a bat MERS-like coronavirus HKU5 uses ACE2 as a receptor from its natural bat reservoir Pipistrellus abramus and American mink. Structural analyses demonstrate a unique interaction between the HKU5 receptor binding domain and bat ACE2. This highlights the receptor flexibility of merbecoviruses and identifies mink as potential intermediate hosts, informing viral surveillance and countermeasure development.

Here the authors design tripeptides that form dynamic soluble dispersions and undergo phase separation upon drying to assemble into porous particles. This evaporation-driven emulsification can be harnessed to encapsulate and stabilize biomolecules.

Analysis of soundscape data from 139 globally distributed sites reveals that sounds of biological origin exhibit predictable rhythms depending on location and season, whereas sounds of anthropogenic origin are less predictable. Comparisons between paired urban–rural sites show that urban green spaces are noisier and dominated by sounds of technological origin.

Using well-calibrated statistical methods the authors jointly analyze Undiagnosed Diseases Network genomes, identifying known and novel disease genes. Software is publicly available to support future cross-cohort rare disease discovery efforts.

Solar flares provide wide range of observational details about fundamental processes involved. Here, the authors show evidence for magnetic reconnection in a strong confined solar flare displaying all four reconnection flows with plasmoids in the current sheet and the separatrices.

Body size and composition are complex traits that are challenging to characterize due to environmental and genetic influences. Here, Arehart et al. disentangle shared and distinct genetic signals underlying body size and composition.

Relaxor ferroelectrics are of interest for applications such as actuators and sensors because of their very large electromechanical responses. Here the authors show that phonon localization drives the generation of the polar nanoregions that explain this electromechanical behaviour.

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.

Proteomic technologies are capable of identifying thousands of proteins in biological samples, but biomarker applications are lagging. Here the authors use Multiple Reaction Monitoring Mass Spectrometry to delineate peptide signatures that accurately distinguish between defined prostate cancer patient risk groups.

It remains unclear why some paediatric tumours appear to have such a low mutation burden. Here, the authors shed light on this paradox by analysing Wilms tumours using high resolution and high depth sequencing approaches, finding that - due to an unusual clonal architecture - standard methods significantly underestimate the mutation burden at the cellular level.

Current intracortical brain-computer interfaces are subject to recording interface instabilities that degrade decoding performance. Here, the authors present a platform for Nonlinear Manifold Alignment with Dynamics (NoMAD), which stabilizes decoding using models of dynamics for at least 3 months.

The fabrication self-sorting supramolecular gels, containing co-existing homomolecular assemblies with similar physical and chemical properties, is challenging. Here pH-controlled self-sorting gelators are reported, where the order of assembly of each component is predetermined by gelator pK_a.

An analysis of 24,202 critical cases of COVID-19 identifies potentially druggable targets in inflammatory signalling (JAK1), monocyte–macrophage activation and endothelial permeability (PDE4A), immunometabolism (SLC2A5 and AK5), and host factors required for viral entry and replication (TMPRSS2 and RAB2A).

Topological magnetic spin structures such as skyrmions and merons have the potential to be used in magnetic information devices. Now multistep transformations between such structures are demonstrated in a centrosymmetric material.

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.

The authors use laser imaging techniques to capture wind dynamics over the ocean. The fine-scale structure of the airflow within the first centimeters above waves reveals the coexistence of different wind-wave coupling mechanisms.

Delivering functional proteins or protein complexes into cells continues to be a significant challenge. Here, the authors develop efficient systems by using engineered extracellular vesicles to deliver functional cargoes, including CRISPR/Cas9-ribonucleoproteins, both in vitro and in vivo.

Multicomponent supramolecular hydrogels have been prepared using a self-sorting mixture of two different gelators—one of which is photosensitive. Irradiation of the gels through a mask leads to the photosensitive network being selectively removed by a light-triggered gel-to-sol transition in a process that can be used to produce patterned gels with spatially controlled properties.

The utilization of waste heat is an important way of combining energy saving to emission reductions. Here, authors demonstrate a magnetocaloric material as a controlling switch in a thermomagnetic generator for waste heat recovery.

Through neutron scattering experiments coupled with machine learning, the authors uncover the strong role of nuclear quantum effects in the dynamics of ammonia in both its solid and technologically relevant liquid phase.

FeGe is a Kagome metal that exhibits a very rich array of magnetic and electronic phases. Here, using neutron scattering, Chen et al add to this zoo, by showing the emergence of a spin density wave order.

The origins of Alpine valleys are controversial. Topographic data from the Swiss Alps suggest that the valleys have been incised progressively during consecutive glacial–interglacial cycles.

Multisystem inflammatory syndrome in children (MIS-C) onsets in COVID-19 patients with manifestations similar to Kawasaki disease (KD). Here the author probe the peripheral blood transcriptome of MIS-C patients to find signatures related to natural killer (NK) cell activation and CD8+ T cell exhaustion that are shared with KD patients.

Tumor-associated myeloid cells directly support progression of T-cell acute lymphoblastic leukemia (TALL). Here, the authors show that T-ALL cells must contact myeloid cells and activate integrin signaling and downstream FAK/PYK2 kinases to survive.
