Föroreningarnas inverkan på fiskuppväxt hotar mediterrane lagunernas värde som växtkammare för kommersiella arter. Forskare undersökte 93 ungdomsfiskar av gilthuvad havsbraxem från tre tunisiska laguner och fann att föroreningar från industriell aktivitet orsakar mätbara missbildningar i otoliter — hörselbenen som styr fiskens balans och orientering. Tunis Lagoon visade högst metallhalter (bly, nickel) och långlivade organiska föroreningar (PCB, DDT, bromerade flamskyddsmedel). Även då muskelkoncentrationer låg under gränsvärdena för livsmedel, påverkade särskilt koppar, rubidium, strontium och DDT otoliternas utveckling. Vänster otoliter visade större asymmetri, tecken på utvecklingsstörning under miljöstress. Resultaten från Frankrike, Tunisien och Sverige erbjuder nya verktyg för att bedöma föroreningsrisker i känsliga lagunhabitats innan effekterna blir synliga i slutna ekosystem eller livsmedelskedjor.

# Vattensplitting-katalysator kan sänka kostnader för grönt väte Forskare vid Central University of Punjab har utvecklat en nanobälte-baserad katalysator som kombinerar krom(III)oxid och mangankoboltkobolt-spinell för bifunktionell elektrokatalytisk vattensplitting. Materialet är designat för att katalysera både syrgasutveckling och väteproduktion i samma reaktor. Studien utfördes vid flera indiska institutioner inklusive Indian Institute of Technology Indore och University of Delhi. Resultaten presenteras i ACS Applied Nano Materials. För grönväteproducenter är detta relevant eftersom bifunktionella katalysatorer kan minska elektrodkomplexiteten och materialkostnaderna i alkalina elektrolysörer. Spinellbaserade metalloxider erbjuder lägre råvarupris än ädelmetallkatalyser. Tiden från laboratorieresultat till kommersialisering beror på katalysatorns effektivitet och stabilitet över många cykler — metriker som inte är specificerade här. Resultatet tillhör ett större utvecklingsfält men kräver verifiering vid pilotskala.

New research reveals a troubling tradeoff: cutting industrial pollution in Africa, Europe, and the U.S. will improve air quality by 5-7% by 2050, but climate feedbacks will simultaneously increase natural dust emissions that partially cancel those gains. For policymakers and businesses planning health and environmental investments, the finding shows that air quality improvements require accounting for knock-on meteorological effects.EN

A new analysis of European climate policy reveals that 'just transitions'—the framework meant to protect workers and communities during green shifts—are being constantly reshaped by competing actors with opposing agendas. The finding matters because businesses and policymakers betting on stable transition rules may find the goalposts moving.EN

Researchers used remote sensing and GIS technology to accurately estimate wheat and barley planting areas in Iraq's Duhok region. The method offers governments and agricultural businesses a faster, cheaper way to monitor crop production and plan resource allocation in data-scarce regions.EN

A new study tracking the pathogen behind Dutch elm disease across Scandinavia reveals subspecies are migrating northward and interbreeding, potentially creating more aggressive strains. For forestry companies, agricultural policymakers, and urban planners, this suggests the disease's range and severity may expand, requiring updated management strategies for one of Europe's most economically damaging forest pathogens.EN

Scientists have developed the first systematic method to assess how marine technologies—including controversial ocean alkalinity enhancement—affect ecosystems during their entire lifecycle. The guidance addresses a critical gap: companies and regulators currently lack standard tools to evaluate whether climate interventions create unintended environmental damage in coastal waters.EN

Researchers have developed a machine-learning system designed to forecast soil moisture patterns across multiple locations simultaneously. The advance could help agricultural businesses and water managers make faster decisions about irrigation, crop planning, and drought preparedness as climate variability increases.EN

Scientists have developed a method to distinguish natural forests from plantations using satellite imagery, a capability that could reshape how companies and governments monitor biodiversity and verify climate commitments. The technique matters because most forest monitoring tools treat all trees equally, obscuring whether lands actually support wildlife or serve primarily as commercial crops.EN

Researchers have overturned a century-old geological assumption about how mountains stay aloft. The Scandes mountains in northern Scandinavia are buoyed by dense rock far below the crust, not by the thickened crustal roots scientists expected. This finding reshapes understanding of passive continental margins—crucial for oil and gas exploration, mineral deposits, and infrastructure planning across stable coastlines worldwide.EN

A new analysis of the EAT-Lancet dietary guidelines identifies seven ways to make plant-forward eating more nutritionally complete and culturally acceptable. The findings matter to food companies, policymakers, and investors betting on the shift away from animal agriculture: solving these gaps could unlock massive dietary transitions without compromising health.EN

The Arctic-Boreal region absorbs more CO2 than it releases—until you count wildfire emissions. A new analysis shows that when fires are factored in, the region's carbon-sink advantage disappears, undermining a key climate buffer and signaling accelerating warming feedback loops that threaten global climate targets.EN

Researchers calibrated four leading lake temperature models across 73 global lakes and found each excels in different conditions—meaning no single tool can reliably predict water temperatures or forecast ecological changes like greenhouse gas emissions.

A 60-year study shows that involving local communities in wildlife protection allows lions to move safely through inhabited areas, reducing extinction risk. But the research also reveals a critical vulnerability: extreme droughts can undo progress by triggering livestock attacks and retaliatory killings, challenging the sustainability of conservation efforts in climate-stressed regions.EN

Researchers found that drainage of acidic sulfate soils in Scandinavia is loading coastal estuaries with toxic metals like cadmium and nickel, degrading water quality and harming fish habitat. The discovery matters because similar acid soils exist across northern Europe and North America, suggesting widespread coastal contamination from agricultural land use that regulators and water companies haven't fully accounted for.EN

A analysis of 25 million people across seven European countries reveals that poorer communities face significantly higher exposure to air pollution and worse built environments—a disparity that varies sharply by location. The finding suggests environmental inequality is not a universal problem but depends on local context, complicating efforts to design one-size-fits-all policy solutions.EN

A new editorial synthesizes research on hydrothermal vents and cold seeps—extreme ocean environments teeming with unique microbial life. Understanding these ecosystems matters for coastal protection, resource extraction, and predicting how ocean chemistry changes will affect marine food webs and fisheries.EN
