The authors find that Ag-rich nanoprecipitates with sizes up to tens of nanometers can be formed in metallic Ag/Ag₂Se composite flexible films after spark plasma sintering. Moreover, Ag-rich nanoprecipitates play a positive role in increasing the carrier concentration, enhancing the density-of-states effective mass, and mitigating carrier scattering.

Translation and rotation are the two most fundamental forms of diffusion. Here, the authors provide evidence of the coupling between rotation and translation under confinement, and find that asymmetric rotations disrupt the order of molecular diffusion in zeolites, which can be applied to studies of selective separation.

Honeybee behavioral plasticity provides a model to study how brain gene networks regulate behavior. Here, authors show stripe activation in Kenyon cells links gene regulatory networks to behavioral maturation via spatial-cellular coordination.

Available eddy-resolved simulations predict turbulent flows accurately but are too computationally demanding for widespread application. This study presents a Conditional Neural Field Latent Diffusion model that efficiently simulates complex spatiotemporal dynamics in turbulent systems, even within challenging 3D irregular domains.

Adult zebrafish possess the ability to regenerate injured hearts through a complex orchestration of molecular and cellular activities. Here, the authors present a single cell and spatially-resolved atlas of the regenerating zebrafish heart, which serves as a valuable resource for research on heart regeneration.

Subsoils are vital for ecosystem sustainability due to their nutrient stocks and microbial diversity. This study across 40 agricultural sites in China found that, compared with topsoils, subsoils are more sensitive and variable under disturbance, highlighting the need to manage both layers in sustainability efforts.

One of the challenges in studies of quantum many-body physics is finding an efficient way to record the large system wavefunctions. Here the authors present an analysis of the capabilities of recently-proposed neural network representations for storing physically accessible quantum states.

Residue-free water disinfection is vital for safe drinking water. Here the authors develop an electrochemical system for microbial eradication by employing a dual-mode mechanism and a dynamic “live microbe capture–killing–dead microbe desorption” process for continuous and effective disinfection.

Neovaginas are surgically constructed to correct uterovaginal agenesis in women with Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome. Here, in a longitudinal study, the authors characterize the dynamics of neovaginal microbiota assembly, showing resemblance to normal vaginal flora at 6-12 months post-surgery, albeit with a bacterial vaginosis-like structure, and further developed into a structure resembling that of the homeostatic pre-surgery dimple microbiota by 2-4 years post-surgery.

An interim analysis of a single-arm trial in 5 children with hereditary deafness shows that binaural AAV gene therapy is safe and leads to hearing improvement up to 13–26 weeks of follow-up.

Using single-cell transcriptomics, the authors generate a brain cell atlas for the pharaoh ant including individuals of different sexes and castes and show changes in cell composition underlying division of labour and reproductive specialization.

The advantage of living in cities compared with rural areas with respect to height and BMI in children and adolescents has generally become smaller globally from 1990 to 2020, except in sub-Saharan Africa.

Methods to stratify patients according to mortality risk are essential to allocate limited heath resources during the COVID-19 crisis. Here, using machine learning methods, the authors present a mortality risk prediction model for COVID-19 that uses patients’ clinical data on admission to stratify patients by mortality risk.

Methotrexate-loaded tumour-cell-derived microvesicles induce neutrophil-mediated antitumour activity and can relieve biliary obstructions in patients with extrahepatic cholangiocarcinoma.

Radiative cooling is a sustainable subambient cooling technology. Here, authors show a scalable and practical design of a dual-selective thermal emitter that is shown to have enhanced radiative cooling potential over existing typical designs.

The magnetism-mediated assembly of non-Brownian magnetic colloidal particles into a three-dimensional oriented and ramified magnetic network yields permanent fluidic magnets that are used in a self-powered, liquid-based wireless cardiovascular sensor.

Here the authors characterize a monoclonal antibody from a COVID-19 convalescent patient that interferes with SARS-CoV-2 spike binding to ACE2 and has prophylactic and therapeutic activity in non-human primates. Antibody-dependent enhancement of infection is prevented by mutating the Fc region of the antibody.

Exercise could affect the immune system, but whether early-life exercise could benefit immune health in adulthood is not fully understood. Here the authors show that early-life exercise promotes epi-metabolic changes in the liver to potentially benefit immunity in older age and characterise the involvement of pipecolic acid in this process.

Agricultural land-use change affects belowground biodiversity. Here, the authors compare soil microbial communities from natural ecosystems and agricultural systems, finding that agricultural conversion leads to taxonomic and functional homogenisation.

Upon pathogen attack, plants can trigger the “cry for help” response and assemble beneficial rhizobacteria. Here, the authors use nonpathogenic Pseudomonas syringae DC3000 derivatives to elicit a similar “cry for help” response as the wild-type pathogenic DC3000 in Arabidopsis.

Based on marine multiproxy records, a new study outlines the role of larger heat discharge of the pan-Arctic Rivers in determining the pronounced sea ice retreat over the East Siberian Arctic Shelf in the mid-Holocene.

Ebola virus virion protein 35 (VP35) is a cofactor of the viral RNA-dependent RNA polymerase, required for viral assembly and IFN antagonist. Here, Zhu et al. provide evidence that EBOV VP35 induces an AKIP1-mediated (human A kinase interacting protein) activation of the PKA-CREB1 signaling pathway and contributes to viral replication and pathogenesis in vitro and in vivo.

Diarrhoea is a major cause of morbidity and mortality in China. Here, the authors present results from a large sentinel surveillance scheme from 217 hospitals in all 31 provinces in mainland China, including ~150,000 patients with acute diarrhoea and covering years 2009-2018.

Toroidic phases and their phase transitions are notoriously hard to study in natural materials. Now, a direct-kagome spin ice provides access to two low-temperature toroidal phases, ferrotoroidicity and paratoroidicity, as well as to toroidic phase transitions.

China operates a national surveillance program for acute respiratory infections and sampled over 200,000 patients between 2009–2019. Here, the authors present results from this program and describe patterns by age, pathogen type, presence of pneumonia, and season.

Although several advances have been made in chemical Polyethylene (PE) re- and upcycling, energy-efficient and selective catalytic processes are still lacking. Here, the authors show coupling of an industrially relevant coordination copolymerization olefins with a functionalized chain-transfer agent, followed by modular assembly of the resulting telechelic polyolefin building blocks by polycondensation to afford ester-linked PE-based random and block copolymers which exhibit full chemical circularity.

Immune cells produce reactive oxygen species (ROS) to eliminate pathogens, but cell-spontaneous death and ageing may also be induced.
