A decade of BGC-Argo and plankton records shows North Pacific heatwaves reshape food webs and trap small particles in midwater, slowing deep-ocean carbon export. Impacts vary by event, underscoring the need for sustained ocean monitoring.

ColdBrew is a machine learning-based method that predicts the probability of cryogenic crystallographic waters to be present at room temperature, which links to their relative energies and displaceability by ligands.

Global trends in species richness in the deep sea are poorly explored. This study uses occurrence records of Asteroidea to show that species richness in the deep benthos is restricted below ~1.5 °C but correlated with temperature and nutrient flux, despite different patterns across oceans and latitudes.

The importance of oxygen in supporting early animal ecosystems is unclear because most proxies are unable to distinguish well-oxygenated from intermediate waters. Here, the authors show that early skeletal animals were restricted to well-oxygenated habitats, suggesting they had a high metabolic oxygen demand.

Agricultural runoff adds sulfate to Florida wetlands, which increases production of toxic methylmercury at moderate sulfate concentrations that is assimilated in fish. The study helps predict wetland responses to management and climate variables.

Marine spatial planning is used to co-ordinate multiple ocean uses, and is frequently informed by tradeoffs and composite metrics. Here, Lester et al. introduce an approach that plans for multiple uses simultaneously whilst balancing individual objectives, using a case study of aquaculture development in California.

The protein corona formed on nanoparticles can impact bioactivity. Here the authors show that the protein corona on lipid nanoparticles alters their function and reduces transfection efficiency, showing the importance of considering the protein corona in designing lipid nanoparticle-based therapeutics.

Demystifying the spawning strategies of fish can help us understand their evolutionary drivers and better inform fisheries management. This study reveals the spawning strategies of pelagic fish, showing that the benefits of co-located spawning across time and space outweigh the potential drawbacks.

Many inland waters seasonally or permanently dry up, thus exposing sediments to the atmosphere. Here the authors show that a substantial amount of CO₂ is emitted from these dry sediments, increasing current inland water carbon flux estimates by 6%.

The ocean emits the greenhouse gas methane, but its vastness renders estimations challenging. Here the authors use machine learning to map global ocean methane fluxes, finding a disproportionate contribution from shallow coastal waters, and a link between primary production and methane cycling.

Zaxinone is a novel ligand of the strigolactone (SL) receptor DWARF14 (D14) in Arabidopsis. It competitively binds the active site of D14 and acts as a long-lasting, non-hydrolysable antagonist of SL by blocking the interaction between D14 and MAX2.

Native state proteomics of PV interneurons revealed unique molecular features of high translational and metabolic activity, and enrichment of Alzheimer’s risk genes. Early amyloid pathology exerted unique effects on mitochondria, mTOR signaling and neurotransmission in PV neurons.

Precambrian rocks host a deep hydrosphere, but where dissolved sulfate, crucial for microbial life, comes from is unclear. At 2.4 km depth in the Canadian shield, Li et al. find that oxidation of sulfides in the host rocks creates sulfate thus providing a long-term mechanism for the deep biosphere sulfate.

Eutrophication increases the acidity of coastal waters. Model simulations suggest that the drop in pH in coastal waters of the northern Gulf of Mexico since pre-industrial times is greater than that expected from eutrophication and ocean acidification alone.

Phaeocystales are ecologically significant nanoplankton whose evolutionary history and functional diversity remain incompletely characterized. Here, the authors integrate genomic and transcriptomic data to reveal their lineage diversification, metabolic plasticity, and adaptation to polar and temperate regimes.

The use of antimicrobial agents can exacerbate the proliferation of antimicrobial resistance genes, which can put public health at risk; evaluating this risk requires proper monitoring. An extensive investigation of Australian wastewater reveals a distinct correlation between the type of antimicrobial used and the socioeconomic status of the population.

Observations from 12 hydrocast stations along a transect crossing the North Atlantic from the subtropical gyre to the northern European shelf provide evidence of large amounts of nanoplastics throughout the entire water column.

Commensal Candida albicans enhances the virulence and dissemination of Salmonella enterica subsp. enterica serovar Typhimurium.

Increasing atmospheric carbon dioxide levels are causing ocean acidification, compromising the ability of some marine organisms to build and maintain support structures. An analysis of mussels from a submarine volcano setting with natural low-pH conditions shows low shell thicknesses and growth rates, but survival over up to four decades.

Lipid nanoparticles (LNPs) are a versatile class of clinically approved drug delivery vehicles, particularly for nucleic acid cargoes, but they often suffer from instability issues. Here, the authors report that the room temperature stability of small interfering RNA LNPs formulated with unsaturated ionizable lipids can be improved by inclusion of mildly acidic, antioxidant-containing buffers.

This study deduces from first principles how sea ice and seawater shape light spectra in fundamentally different ways. The loss of sea ice may thus trigger changes in both the pigment and species composition of primary producers in polar ecosystems.

Mellor et al. report that deficiency of GABARAPL1, an ATG8-specific linking protein, impairs diastolic function in diabetic mice. This effect can be reversed by gene delivery of the gene encoding GABARAPL1 in diabetic mice and a human organoid model of type 2 diabetes.

The Panoptes antiphage system defends bacteria by detecting phage-encoded counter-defences that sequester cyclic nucleotide signals, triggering membrane disruption and highlighting a broader strategy of sensing immune evasion through second-messenger surveillance.

A mass spectrometry-based approach globally identifies protein regulators of metabolism and reveals the role of LRRC58 in controlling cysteine catabolism.

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.

The Antarctic Circumpolar Current (ACC) since the Last Interglacial is reconstructed, showing orbital-scale shifts in ACC position driven by eccentricity and precession, possibly counteracting the predicted southward shift due to global warming.

Whether paternal pre-conceptual SARS-CoV-2 infection impacts sperm RNA content, or effects offspring phenotypes, has not been previously investigated. Here authors report changes in sperm noncoding RNAs in SARS-CoV-2 infected sires and increased anxiety-like behaviors in offspring.

The photosynthetic production of oxygen in the ocean is thought to have begun at least 2.7 billion years ago. The geochemistry of marine sediments deposited 2.6 billion years ago suggests that ocean margins were oxygenated at least 100 million years before the first significant increase in atmospheric oxygen concentrations.

A post-translational backbone extension acyl rearrangement (BEAR) reaction has now been developed that converts a ribosomal protein product into a new product containing a β-peptide, γ-peptide or δ-peptide backbone. BEAR reactions represent a general strategy to install extended backbones into genetically encoded proteins and peptides expressed in cells.
