Understanding these ecosystems matters for coastal protection, resource extraction, and predicting how ocean chemistry changes will affect marine food webs and fisheries.EN

A 3,000-year sediment analysis reveals that land-use changes—not just modern industry—fundamentally altered nutrient cycling in the Baltic Sea. The finding suggests policymakers must address agricultural practices spanning centuries, not just recent decades, to restore coastal water quality and protect fisheries worth billions annually.EN

Scientists say biodiversity forecasts are dangerously incomplete because they ignore how climate change reshapes land use—triggering deforestation, development, and habitat conversion that amplifies wildlife decline. Better integration of land-use and climate models is essential for accurate planning and investment decisions in conservation and land management.EN

Researchers have identified photosynthetic microorganisms—algae and cyanobacteria—that can break down microplastics in water and soil while simultaneously converting sunlight and CO2 into useful compounds like proteins and lipids. The finding could enable a self-sustaining cleanup technology with economic value, offering businesses and governments a potentially cost-effective remediation pathway for one of the planet's most pervasive pollutants.EN

Understanding these plasma dynamics matters to telecom, energy, and aerospace sectors that depend on accurate space weather forecasting.EN

A Swedish research team extracted a 2-km-deep rock core capturing 500 million years of geological history, revealing how two ancient continents collided to form Scandinavia. The findings could improve understanding of how similar tectonic events created mineral deposits and shaped subsurface conditions—insights valuable for energy exploration, carbon storage, and geothermal resource development.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

Researchers have identified genetic markers that predict brain deterioration in cognitively normal adults years before memory problems emerge. The finding could enable early screening and intervention strategies, reshaping how companies approach insurance risk assessment and how health systems allocate preventive care resources.EN

New research reveals that frozen Arctic soils currently absorb more carbon dioxide than they release—but this carbon sink is fragile and shrinking toward the poles. As permafrost thaws from climate change, it risks unleashing vast methane stores, threatening climate targets and forcing costly revisions to emissions forecasts that underpin corporate and government climate strategies.EN

A Norwegian university in Svalbard has developed a novel graduate program using the Arctic's extreme geology—volcanism and tectonic activity—as a living laboratory for students. The approach demonstrates how remote, data-poor regions can become valuable research hubs, potentially lowering costs and expanding access to climate and Earth science expertise globally.EN

Researchers found that combining digestate—a byproduct of biogas production—with phosphogypsum, a waste product from fertilizer manufacturing, can effectively trap heavy metals in polluted soil. The finding offers waste management companies and soil remediation firms a low-cost way to address contamination while repurposing industrial waste streams.EN

Researchers found that sea spray aerosols are releasing persistent fluorinated pollutants back into the atmosphere at rates rivaling all known industrial sources combined. The discovery upends assumptions about where these toxic 'forever chemicals' circulate globally, with implications for air quality regulations, chemical restrictions, and long-term environmental liability across industries.EN

Researchers modified a common cyanobacterium to pump out fatty acids—the building blocks of biofuel—when facing harsh conditions like salt exposure and nutrient scarcity. The breakthrough could enable more efficient production of renewable oils from engineered microorganisms, potentially opening a scalable alternative to fossil fuels and agricultural feedstocks.EN

A major review of how researchers quantify nature's worth identifies three distinct value frameworks: intrinsic (nature's inherent worth), instrumental (what it does for us), and relational (our connection to it). The finding could help policymakers and businesses move beyond conflicting valuations to make more effective conservation and environmental decisions.EN

Scientists have reconstructed the world's earliest marine food webs from 500-million-year-old fossils, revealing how predatory animals fundamentally altered ocean chemistry and atmospheric cycles. The findings suggest that the emergence of consumer-driven ecosystems—not just photosynthesis—was critical to shaping Earth's climate, with implications for understanding how biodiversity drives planetary systems today.EN

A first-of-its-kind analysis of peatland fire records across three continents shows that climate shifts—not just human activity—drive dangerous carbon release from these carbon-rich ecosystems. As global temperatures rise, the findings suggest peatland fires could accelerate, threatening major atmospheric carbon releases and complicating climate mitigation strategies.EN

Researchers sequencing leatherback and green turtle genomes discovered that the two species evolved radically different sensory and immune systems to survive distinct ocean environments. The findings could reshape how conservationists breed and protect declining populations, and offer clues about how marine animals adapt to climate-driven habitat shifts.EN

Scientists have released two decades of flood prediction data and daily real-time forecasts through a free public platform, enabling governments and businesses to better prepare for extreme weather. The system accurately predicts river flooding in over 93% of the world's catchments, offering a critical tool for protecting infrastructure and lives as climate change intensifies hydrological extremes.EN

Researchers in Svalbard have deployed a network of automated weather stations across a remote fjord to monitor atmospheric conditions in one of Earth's fastest-warming regions. The freely available data could improve weather forecasting, support offshore operations, and help scientists understand how Arctic warming reshapes global climate patterns.EN

A new study shows that planting trees, creating green spaces, and other nature-based solutions, when deployed strategically across European cities, could eliminate more than half of urban carbon emissions by 2030. The research suggests that smart spatial planning of these solutions—combined with existing climate measures—makes carbon neutrality achievable for early-adopting cities within this decade.EN

A new study reveals that rising seawater temperatures consistently favor slow-growing bacteria over fast-growing ones—a shift that's independent of nutrient changes. The finding provides a framework for predicting how microbial communities will evolve as oceans warm, with implications for fisheries, carbon cycling, and marine ecosystem health.EN

Svenska kommuner implementerar digitala klimatlösningar långsammare än pilotprojekten föreslår. En undersökning av elva kommuner i Viable Cities-initiativet identifierar vad som krävs för att skala lösningarna från försök till faktisk drift. Huvudproblemet är symbolisk adoption — kommunerna anammar verktygen utan att faktiskt integrera dem i dagliga arbetsprocesser. Mellanledningen motarbetar ofta förändringen, och begreppsförvirring gör det svårt att mäta framgång. Forskarna från Göteborgs universitet fann att framgångsrik skalning kräver tre villkor: stabil ledning som driver arbetet långsiktigt, integration i befintliga rutiner, och strategisk användning av offentlig upphandling för att låsa in efterfrågan. Kollegiala nätverk mellan kommuner sprider kunskap effektivt, men låg organisatorisk kapacitet bromsar många. Resultaten omvärderar hur innovation faktiskt sprids — processen är inte linjär utan kräver strukturell förankring för att lyckas.

A new analysis of wastewater treatment plants reveals that the EU's stricter pollution standards could drive up chemical costs by 50% depending on how utilities implement them.
