Zhang et al. show that decreasing mitochondrial pyruvate carrier expression redirects glycolytic intermediates and leads to heart failure, which is prevented or reversed with a high-fat or ketogenic diet.

The role of non-structural carbohydrates (NSC) in mediating the impacts of drought in tropical trees is unclear. Here, the authors analyse leaf and branch NSC in 82 Amazon tree species across a Basin-wide precipitation gradient, finding that allocation of leaf NSC to soluble sugars is higher in drier sites and is coupled to tree hydraulic status.

A study reports the measurement of the polarization degree and angle of X-rays from Sagittarius A^* reflected off a nearby cloud, indicating an X-ray flare about 200 years ago.

Authors explore the utility of CD5L for treating experimental sepsis. CD5L deficiency exacerbates experimental sepsis. Conversely, administration of recombinant CD5L in WT mice augments neutrophil function, enhances bacterial control, and mitigates inflammation, leading to substantial improvements in disease outcomes.

The Amazon rainforest is dominated by relatively few tree species, yet the degree to which this hyperdominance influences carbon cycling remains unknown. Here, the authors analyse 530 forest plots and show that ∼1% of species are responsible for 50% of the aboveground carbon storage and productivity.

Laboratory experiments reveal the underlying mechanism of turbulent reconnection, including electron acceleration. These findings are directly relevant for studies of flares in the solar corona.

The cystic fibrosis transmembrane conductance regulator anion channel can adopt an alternate conformation of its nucleotide-binding domain, which affects channel activity and, under certain conditions, leads to unfolding and protein degradation.

A pan-Amazon study of forests shows large variations in drought tolerance traits and finds that forests in regions of pronounced climate change are losing biomass and may be operating beyond their hydraulic limits.

Whether or not marine protected areas (MPAs) deliver positive outcomes for both people and nature remains a challenging question. Using a statistical matching approach, this study provides quantitative evidence of co-benefits for fish and people associated with MPAs in the Mesoamerican region.

The world’s tropical forests represent a terrestrial carbon sink, yet its size is uncertain. Espírito-Santo et al.characterize full Amazon disturbances combining forest inventories and remote sensing data, and use statistical modelling to quantify the Amazon aboveground forest carbon balance.

Sah and colleagues show that the volume-sensitive ion channel SWELL1 regulates adipocyte insulin-PI(3)K-AKT2 signalling, glucose uptake and lipid content through interactions with GRB2/Cav1.

The impact of the DART spacecraft on the asteroid Dimorphos is reported and reconstructed, demonstrating that kinetic impactor technology is a viable technique to potentially defend Earth from asteroids.

Keratinocytes require glucose for injury- or inflammation-driven but not homeostatic proliferation, and glucose-transport blockade blocks psoriasis-like pathology in experimental models.

A targeting method for lentiviral vectors relying on the use of single-chain antibodies recognizing cell-surface antigens is applied to generate lentiviral vectors specific for endothelial cells, hematopoietic progenitors and neurons.

Analysis of age of onset and disease duration in a large, international cohort of people with SOD1-ALS shows that there is a distinct phenotype and that onset and progression are decoupled.

Chromatin looping plays an important role in gene regulation and the ability to manipulate loops would aid in understanding how this occurs. Here the authors present CLOuD9, a system that uses dimerized Cas9 complexes to selectively and reversibly establish chromatin loops.

A study comparing the pattern of single-nucleotide variation between unique and duplicated regions of the human genome shows that mutation rate and interlocus gene conversion are elevated in duplicated regions.

The behavior of exosomes in vivo is not completely elucidated. Here the authors develop a genetically engineered mouse model (ExoBow) to trace the distribution of exosomes, showing local and inter-organ communication networks, either specific or shared between healthy pancreas and pancreatic ductal adenocarcinoma.

Emelia Benjamin and colleagues report a meta-analysis of genome-wide association study data for atrial fibrillation, a condition associated with stroke and heart failure, in five European community-based cohorts of the CHARGE consortium. They report an association in ZFHX3 to atrial fibrillation, with replication in an independent cohort from the German AF Network.

Comprehensive multi-omics of Babesia duncani reveals evolution, drug sensitivity and virulence.

The function of RNA-binding domain abundant in Apicomplexans (RAP) protein family members is largely unknown. Here, using high-throughput functional genomics, including metabolomics, Hollin et al. characterize two RAP proteins that are essential for Plasmodium falciparum survival and control mitochondrial rRNAs.

CDK4/6 inhibitor resistance is common in breast cancer. Here, the authors show that p16 overexpression may be linked to reduced efficacy of CDK4/6 inhibition, and show that the combination with PI3K inhibitors may increase anti-tumour effects.

Alterations in cis-regulatory elements (CREs) can contribute to pancreatic diseases. Here the authors combine chromatin profiling and interaction points with in vivo reporter assays in zebrafish to uncover functionally equivalent human CREs, helping to predict disease-relevant enhancers.

Experimental simulations of galaxy-forming conditions using lasers show that the Biermann battery generates seed magnetic fields, which turbulence can amplify to affect galaxy evolution.

Herpes simplex virus-1 encephalitis is linked to variants in a small nucleolar RNA, suggesting a new mechanism for antiviral immunity in cortical neurons.

Historical accounts of the mortality outcomes of the Black Death plague pandemic are variable across Europe, with much higher death tolls suggested in some areas than others. Here the authors use a ‘big data palaeoecology’ approach to show that land use change following the pandemic was spatially variable across Europe, confirming heterogeneous responses with empirical data.

In laboratory experiments, strong magnetic fields at the boundary of a plasma can be generated by means of laser-wakefield acceleration, enabling the study of magnetization processes in scaled versions of astrophysical plasmas.

Opinions on climate policy in the United States are politically polarized. Here, survey research shows that opinion polarization on the Green New Deal developed rapidly due to decreasing support among Republicans, which was associated with exposure to conservative media and increasing familiarity with the policy.

Efficient, large-scale genomic analysis is facilitated on the cloud by a computational tool with error-diagnosing and self-healing capabilities.

It is unclear how metabolic regulation affects development of the skeleton. Here, the authors show that deletion of the glucose transporter Glut1 (Slc2a1) both prior to and following chondrogenesis in the mouse limb impairs chondrocyte proliferation and shortening of the limbs, modulated by BMP signaling.

Germline mutations in the DNMT3A gene can cause an overgrowth syndrome associated with behavioural and hematopoietic phenotypes. Here the authors describe a mouse model of this syndrome that recapitulates many of these features, including conserved alterations in DNA methylation in the blood cells of both species.

Dumesnil et al. report that cholesterol esters (CE), which only melt above body temperature, form supercooled liquid crystalline lipid droplets (LD). Triacylglycerols (TG) solubilize CE to help CE LD nucleation. Through clustering TGs in the ER membrane, seipin controls CE LD nucleation sites.

GM-CSF is involved in control over M. tuberculosis infection. Here the authors show that GM-CSF reduces type 1 interferon driven neutrophil recruitment, NETosis and bacterial growth in the lungs of infected mice, and provide evidence that this NETosis occurs in infected humans who are not responsive to antibiotic therapy.
