The authors show that ~100-kyr climate cycles over the past ~800 ka, and even since ~34 Ma, likely arose from a ~2.4-Myr eccentricity-modulated competition between low- and high-latitude continental carbon reservoirs for dominance in carbon cycles.

A cross-sectional study of hospitalized patients with COVID-19 and a longitudinal follow-up study of patients with COVID-19 suggest that SARS-CoV2-specific IgG or IgM seroconversion occurs within 20 days post symptom onset.

Here the authors investigate the involvement of the immune modulator ILF3 in abdominal aortic aneurysm, showing that macrophage ILF3 promotes aneurysm progression by increasing NF-kB activity and inhibiting Keap1-Nrf2 signaling.

A deep learning algorithm shows promising performance in predicting progression to diabetic retinopathy in patients, up to 5 years in advance, potentially providing support for medical treatment decisions and indications for personalized screening frequency in a real-world cohort.

A meta-analysis of genome-wide association studies of type 2 diabetes (T2D) identifies more than 600 T2D-associated loci; integrating physiological trait and single-cell chromatin accessibility data at these loci sheds light on heterogeneity within the T2D phenotype.

The composition of lipid nanoparticles for the delivery of tumour-antigen-encoding mRNA can be optimized via a screening method to enhance antitumour activity via the modulation of the immune activity of helper T cells.

The role of the tumor microenvironment in immunotherapy response in intrahepatic cholangiocarcinoma remains unclear. Here, single cell RNA and TCR sequencing of samples before and after immunotherapy highlights the role of CD8 T-cell status conversion and exhaustion induced by Macro CD5L+ in treatment response.

Consuming fish oil is linked to reduced risk of cardiovascular disease in some populations, but the effects are not consistent across studies. Here the authors report that smooth muscle cell AMPKα2 is required for the protective effects of fish oil on atherosclerosis in mice, and acts via post-translational regulation of the fatty acid receptor GPR120.

Unstable and harsh climates have been implicated as partial causes of Neanderthal demise. Here a speleothem palaeoenvironmental record spanning the Middle to Upper Palaeolithic transition attests to stable and moderate conditions in the Mediterranean during this time suggesting a more complicated picture than previously thought.

It is difficult to control the geometric phase of particles as they undergo quantum tunnelling. Now tuning of the geometric phase of electron spin is demonstrated in tunnelling in a multilayer van der Waals antiferromagnet.

It has been proposed that, during development, clonally related neurons migrate along the same radial glial fibre to form clusters of functionally similar cells; here, sister neurons in the same radial clone are shown to have similar orientation preferences in mice, providing support for this hypothesis.

Long-distance V(D)J recombination is facilitated by contraction of the Igh locus and linear RAG scanning along chromatin, both driven by cohesin-mediated loop extrusion, which allows recombination of widely separated gene segments to occur.

The authors present a frequency-adjustable ferroelectric heterojunction based on K_0.5Na_0.5NbO₃ piezoelectric ceramic, which enabling therapeutic effects in a myocardial infarction animal model by long-term and high-precision transcranial neuromodulation.

Zhong et al. report a CuInP₂S₆ photodetector array that leverages microscopic ion–electron interactions to achieve tuneable photoresponse with light wavelength and intensity. These capabilities enable in-sensor image processing and offer potential assistance for addressing visual deficiencies, such as color blindness.

Understanding the utility of SARS -CoV-2 vaccination platforms and strategies through the emerging pandemic and beyond are critical to understanding the efficacy of such interventions. Here the authors assess nasal delivery of an influenza virus based viral vector for vaccination against SARS-CoV-2 in a hamsters model and assess the induced immunity.

Cell division is governed by the positioning of a cytoskeletal structure called the spindle. Two methods, one based on laser ablation and the other on fluid flow assessments, are now shown to be useful tools for studying spindle positioning.

This study elucidates that d-galacturonic acid and d-glucuronic acid regulate apple fruit softening by repressing MdHb1 expression through the MdMYB2/MdNAC14/MdNTL9-MdHb1 regulatory module, offering new insights into postharvest fruit quality control.

Anomalous conducting behavior of solids may reflect the presence of novel quantum states. Here, Zhang et al. report an increased conductivity in TaAs with a magnetic field applied along the direction of the current, which reveals an inherent property of the Weyl Fermion.

Summertime rainfall over South Asia has declined in the last few decades, possibly due to human aerosols. Here, the authors present a record of Indian monsoon rainfall over the last two millennial and suggest that large natural variability may mask any forced changes in monsoon.

In three-dimensional metals, topological objects known as Weyl nodes can arise from a crossing of the conduction and valence bands. Experiments under high magnetic fields show how Weyl nodes of opposite chiralities can move together to annihilate.

Organic nitrates have potential to enhance efficacy of bioactive molecules and in some cases can reduce side effects, but selective and efficient methods for their synthesis are generally scarce. Here, the authors present a methodology to difunctionalize alkenes, adding a nitrooxy and halogen in high regioselectivity via a hypervalent iodine reagent.

Low level of pyruvate kinase M2 (PKM2) activity in cancer cells is essential for the dependence on aerobic glycolysis. Here the authors show that PKM2 sulfhydration by hydrogen sulfide destabilizes the PKM2 tetramer, leading to reduced PKM2 enzyme activity and enhanced proliferation of breast cancer cells.

Using two cohorts, Liu, Ge, Xiao, Lu and colleagues perform plasma metabolomics and lipidomics, linking reduced sarcosine to sarcopenia diagnosis. In mice, they demonstrate that sarcosine enhances muscle repair, boosts adipose thermogenesis and preserves muscle mass via macrophage modulation.

The regulation of perovskite crystallization is essential for achieving efficient solar cells. Here, authors introduce K₂SnO₃ to induce formation of KI and PbSnO₃ with an ABX₃ structure to enhance film uniformity, achieving efficiency of 28.81% for four-terminal all-perovskite tandem solar cells.

Analysis of ancient DNA, stable isotope data and archaeological evidence from the Fujia archaeological site in eastern China suggests it was populated by a matrilineal Neolithic community between 2750 and 2500 bc.

Azulene-based conjugated systems are of great interests due to their unusual structures and photophysical properties but incorporation of a transition metal into azulene skeleton presents remains elusive. Here, the authors describe an efficient [5 + 2] annulation reaction for the rapid construction of a metalla-dual-azulene.
