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.

Most patients with B-cell leukemia respond to chimeric antigen receptor T cell (CAR T) therapy, yet many relapse due to loss of CAR T function. Here, the authors show that the metabolism of CAR T from short- and long-term responders is different, which may explain why CAR T lose functionality.

Dynamos can generate magnetic fields, which are present across various scales in space plasmas. Here, the authors show evidence for a turbulent dynamo in the terrestrial magnetosheath, indicating that Earth’s magnetosheath may be used as a natural laboratory for testing dynamo theories and simulations.

Here, the authors use high-resolution mapping and observe exponential decay from the edge of four precursors to coral aragonite skeleton in Stylophora pistillata.

Most studies assessing food self-sufficiency look at calories and neglect nutrient gaps. Comparing food demand and potential food production under land and water constraints, this study quantifies 9 key nutrient gaps for each of African’s 54 countries.

Therapy to allergy often targets a specific allergen without addressing cross-reactivity. Here the authors develop a consensus, cross-reactive allergen, use mRNA-lipid nanoparticle immunization to induce specific, neutralizing IgG responses, but find no therapeutic effects in mouse allergy models, hinting the need for further optimization prior to translation.

DNA methylation heterogeneity and dynamics hinder distinguishing early pathological changes from normal variation. Here, the authors identify stable sites whose disruption is linked to blood cancers, aging, and cardiovascular risk.

Multiple myeloma involves alterations to T cell function, but mechanisms underlying disease evolution remain unclear. Here the authors find that, unlike solid cancers, multiple myeloma lacks exhausted T cells and is instead characterized by antigen-driven terminal memory T cell differentiation, which may be driven by tumour-intrinsic features including tumour burden and antigen-presentation gene expression.

Long-term patterns of physical activity and the importance of consistent adherence to the recommended level remain poorly understood. Here, the authors show that maintaining physical activity over the long term offers added benefits beyond activity volume alone for chronic disease prevention.

Here, the authors propose the Antarctic Ecosystem Value Index, an Earth systems model-based measure of marine ecological value. The index identifies potential present and future high-value locations, which often fall within coastal polynyas.

A technique called condense-seq has been developed to measure nucleosome condensability and used to show that mononucleosomes contain sufficient information to condense into large-scale compartments without requiring any external factors.

Freshwater ecosystems and biodiversity are declining quickly. By integrating global environmental, socioeconomic, and biological data, this study identifies the key conditions associated with imperilment of freshwater fishes.

Werner et al. present the results of the 201 Trial, a 12-week randomized, double-blind placebo-controlled phase 2a study of risvodetinib, in patients with early untreated Parkinson’s disease. Risvodetinib was found to be safe and well tolerated.

Humans alter the daily timing of animal activity, potentially reshaping predator–prey interactions. This meta-analysis reveals that larger species tend to “lose” under human disturbance, with large predators overlapping less with their prey, and large prey overlapping more with their predators.

This trial found spinal cord stimulation was well tolerated in people with gait-impaired Parkinson’s disease. It suggests that longer use improved lower-body motor symptoms while reducing thalamic hypermetabolism and cholinergic overactivity.

Native top-down proteomics reveals epidermal growth factor receptor–estrogen receptor-alpha (EGFR–ER) signaling crosstalk in breast cancer cells and dissociation of nuclear transport factor 2 (NUTF2) dimers to modulate ER signaling and cell growth.

The burden of dengue disease in infants has increased in Brazil over the last 25 years. Here, the authors analyse spatiotemporal heterogeneity in disease incidence to characterise the contribution of changing maternal immunity to infant dengue risk.

KRAS is an oncogene that switches between a GDP-bound inactive state and a GTP-bound active state. Recently developed KRAS G12C inhibitors are specific to the GDP-bound inactive state. Here, the authors develop a class of covalent KRAS G12C inhibitors capable of targeting both states for the treatment of KRAS-driven cancer.

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.

Plasma p-tau217 tests used to develop clocks that predict when cognitively unimpaired individuals would develop symptoms of Alzheimerʼs disease.

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.

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.

Polyamides (PAs) or nylons are types of plastics with wide applications, but due to their accumulation in the environment, strategies for their deconstruction are of interest. Here, the authors screen 40 potential nylon-hydrolyzing enzymes (nylonases) using a mass spectrometry-based approach and identify a thermostabilized N-terminal nucleophile hydrolase as the most promising for further development, as well as crucial targets for progressing PA6 enzymatic depolymerization.

Interferon-activated natural killer cells attack the immune helpers that support antibody development against multiple SARS-CoV-2 variants.

It is unclear whether the harsh abiotic conditions of drylands hinder biological invasions. This global analysis shows that drylands are vulnerable to non-native plants and are likely to become more so as native plant diversity declines and grazing pressure intensifies.

In a study of four brain-dead human decedents, extracorporeal liver cross-circulation using genetically modified pig livers provides essential hepatic functions, supporting the feasibility of this approach for temporary liver support as a bridge to organ transplantation.

In a randomized experiment in Chelsea, Massachusetts, USA, lower-income individuals who received cash transfers reduced calorie deficits and increased consumption of nutrient-dense, higher-cost foods. Their findings highlight the critical role that income support may have in a high-income country to reduce hunger.

While therapies targeting type I BRAF mutations have been developed, there are limited options for those with type II and III mutations. Here, the authors identify a subset of BRAF-mutant non-small cell lung cancer patients and characterise the pan-RAF inhibitor exarafenib, demonstrating efficacy in preclinical models and investigating subsequent resistance mechanisms.

Vestibular schwannomas that are caused by genetic mutations in the NF2 gene are hard to treat and lead to hearing loss. Here authors show in a mouse model that faithfully represents the human condition that combination therapy with anti-PD-1 and anti-VEGF inhibits tumor growth via normalizing the tumor vasculature and enhances T and NK cell antitumor cytotoxicity via upregulation of NKG2D.

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.
