Most H₂ used in the chemical industry is derived from fossil fuels. Now it has been shown that coupling native microbial H₂ pathways with engineered alkene biosynthesis and membrane-bound Pd catalysis enables biocompatible hydrogenation of metabolic intermediates in living bacteria. This hybrid chemo-microbial platform supports the carbon-negative synthesis of industrial chemicals from waste-derived feedstocks.

‘Populations residing near nuclear power plants may experience low-level chronic exposure to ionizing radiation through environmental release pathways. In here the authors find higher cancer mortality rates in U.S. counties closer to operational nuclear power plants, with the strongest relative risks observed in older adults.’

This manuscript from Choquette and colleagues finds that sclerostin gene expression is up-regulated in bone by β3-adrenergic signaling via an adipose to bone relay and acts as an endocrine factor to inhibit adipose tissue beiging in mice.

Kelvin waves are elementary excitations of vortex lines, manifesting as propagating helical disturbances in rotational flows. Through spatiotemporal imaging, experimental verification of their dispersion relation has now been achieved.

Neuroinflammation triggers DNA damage and subsequent parthanatos-mediated neuron death. Inhibiting parthanatos in a mouse model of autoimmune inflammation is neuroprotective and reduces disease-associated paralysis.

Circulating tumor cell (CTC) clusters are key drivers of metastasis, yet their formation in tumors lacking classical adhesion molecules is unclear. Here, the authors discover that hyaluronic acid promotes homotypic and heterotypic CTC clustering by initiating early cell contacts and stabilizing mature interactions.

This study shows how the bacterial retron Eco2 defends against viruses. Phage nucleases trigger activation of Eco2, which cuts RNAs, shuts down protein production and stops phage replication.

The combination of within-species variation in pathogen load, the shape of the relationship between pathogen load and infectiousness, and vector feeding preferences shape transmission of multi-host vector-borne pathogens. Here, the authors use experimental and wild bird infection data to characterize the role of 17 host bird species in avian malaria transmission in Hawaii.

CD44 expressed by fibroblastic reticular cells in secondary lymphoid organs regulates trafficking of dendritic cells, and thus has an essential role in the priming of T cells and the adaptive immune response.

The APOE-ε4 allele is the strongest genetic risk factor for late-onset Alzheimer’s disease, but it is not deterministic. Here, the authors show that common genetic variation changes how APOE-ε4 influences cognition.

This study detects Chlamydia pneumoniae in human retina and brain, increasing with AD severity. Retinal pathogen load with Aβ₄₂ may predict AD stage. In models, infection drives Aβ deposition and NLRP3 activation, worsening pathology and cognition.

Mouse models demonstrate that vagal sensory neurons transmit signals from lung adenocarcinoma to the brain, increasing sympathetic efferent activity in the tumour microenvironment and thereby creating a immunologically permissive environment for tumour growth.

This study utilized a longitudinal cohort of adolescents to identify distinct brain signatures linked to ADHD symptom trajectories, revealing that specific cortical and subcortical changes correlate with symptom persistence, remission and emergence, enhancing predictive capabilities for ADHD outcomes.

Hepatic glycogenolysis is essential for protein glycosylation and rhythmic secretion by the liver. Disruptions to hepatic glycogenolysis, caused by congenital diseases or physiological factors such as obesity, caloric restriction and changes to meal timing, alter hepatic protein secretion.

The lowest-frequency gravitational wave background may be shaped by supermassive black hole binaries that scatter nearby stars or dark matter. In this case, the NANOGrav 15-year dataset favours dense galactic centres with 10⁶ solar masses per cubic parsec.

Non-invasive strategies to detect and track activated myeloid cells will facilitate disease diagnosis and monitoring in patients affected by neuroinflammatory disorders. Here, the authors present 18F-FMD, a dendrimer-based PET tracer that detects and monitors activated myeloid cells at different stages (presymptomatic and symptomatic) of Experimental Autoimmune Encephalomyelitis (EAE) in mice and in response to disease-modifying therapies.

The authors present a genetically encoded tool based on a bifunctional enzyme that can regenerate NAD⁺ while executing an engineered glycerol shunt. The tool successfully restored redox imbalance and modulated lipid metabolism in vitro and in a mouse hepatic steatosis model.

Plasmodium vivax reticulocyte binding protein 2b (PvRBP2b) is important for invasion of reticulocytes and PvRBP2b antibodies correlate with protection. Here, Chan et al. isolate and characterize anti-PvRBP2b human monoclonal antibodies and describe mechanisms by which these antibodies inhibit invasion.

A population genomic analysis of 1,854 Listeria soil isolates collected across the contiguous United States identifies geographically prevalent phylogroups with increased pangenome openness and recombination, as a result of adaptation to variable environments.

From 2014–2017, marine heatwaves caused global mass coral bleaching, where the corals lose their symbiotic algae. The authors find, this event exceeded the severity of all prior global bleaching events in recorded history, with approximately half the world’s reefs bleaching and 15% experiencing substantial mortality.

Crohn’s disease is associated with disturbances in the B-cell compartment and secreted antibodies. Here, the authors reveal impaired colonic dimeric IgA responses in patients with Crohn’s disease and verify this phenotype in murine models, demonstrating that mitochondrial dysfunction drives defective mucosal humoral immunity.
