Researchers mapping the European High Arctic have identified an unusually thick and dense section of Earth's crust beneath the Varanger Peninsula—a geological anomaly that challenges understanding of how continental crust forms. The discovery could reshape models used in resource exploration and climate-relevant studies of Arctic geology.EN

When Iceland's Lakagígar volcano erupted in 1783, it triggered a chain reaction across Sweden: crop failures, grain shortages, soaring prices, and a mortality spike lasting two years. The study maps how compound climate disasters compound human suffering—a warning for policymakers and businesses preparing for similar risks today.EN

Researchers have identified a biological signature that reveals when massive plankton blooms ended millions of years ago, offering a new tool to track ocean productivity shifts. The finding could help predict how today's oceans might respond to warming and changing nutrient conditions.EN

Researchers have developed a copper-based catalyst that converts CO2 directly into acetate, a building block for chemicals and fuels. The breakthrough could help industries reduce emissions while creating value from captured carbon—a key step toward making carbon capture economically viable at scale.EN

Researchers have developed a molecular platform that improves water-splitting catalysis, a critical step toward converting sunlight directly into usable fuels. The coordination-adaptive approach could accelerate commercial deployment of artificial photosynthesis systems, reducing reliance on fossil fuels while creating new markets in green hydrogen and synthetic fuels.EN

Researchers have validated implants that deliver pharmaceutical doses to free-swimming fish, offering the first reliable method to measure real-world drug contamination impacts on wildlife. The finding matters to regulators, pharma companies, and water utilities facing pressure to understand pharmaceutical pollution risks across entire ecosystems.EN

The Nordic countries launched a new mobility program in 2025 to eliminate bureaucratic obstacles for workers, students, and entrepreneurs crossing borders. The initiative targets competitive disadvantages from fragmented markets, positioning the region to better compete globally while simplifying operations for multinational companies.EN

Researchers have identified a technique to detect large, previously invisible chemical byproducts created when water treatment plants disinfect drinking water. The discovery matters because these undetected compounds may pose health risks—and water utilities now have a tool to monitor and reduce them.EN

A new study of Swedish wildfire survivors reveals that disasters damage far more than forests and homes—they disrupt people's sense of time, belonging, and generational continuity. For policymakers and business leaders planning disaster resilience, the finding suggests recovery strategies must address psychological and social fractures, not just physical reconstruction.EN

Swedish researchers found that schools have particularly high concentrations of polychlorinated alkanes—chemicals used in flame retardants and plastics—in indoor dust and surface films. The discovery suggests building ventilation and age significantly influence toxic chemical buildup, with implications for facility management, product regulation, and indoor air quality standards.EN

Swedish researchers found that beetle populations respond very differently to forest cover depending on latitude and longitude—a pattern that flips the conventional wisdom about habitat protection. For forestry companies and conservation planners, this means a one-size-fits-all approach to forest management won't work, and strategies must account for subtle geographic factors to protect biodiversity.EN

A new analysis of agricultural policy across EU and Swedish governance levels reveals that digital farming technologies are widely promoted, yet policy documents rarely spell out how they combat climate change or protect biodiversity. For agritech companies and policymakers, the finding exposes a critical gap: without explicit linkage to environmental outcomes, investment in farm digitalization may not deliver the sustainability returns governments expect.EN

Researchers have developed a precise method to detect invisible fluoride pollution that was skewing water quality measurements. The breakthrough matters because industrial and environmental regulators rely on these tests to monitor contamination from forever chemicals—and inaccurate results could hide genuine risks to drinking water supplies.EN

Researchers have developed a decision-support system that uses flood forecasts to help emergency managers allocate resources where they'll do the most good—protecting critical infrastructure and services. As climate change makes flooding more frequent and severe, the tool could help municipalities and utilities reduce cascading failures and economic losses during disasters.EN

Researchers have developed a method that automatically transfers semantic labels from building design models to 3D scans, eliminating months of manual annotation work. For construction firms and engineers deploying AI to analyze building performance and safety, this breakthrough could cut dataset preparation costs by half while accelerating AI model deployment in the field.EN

Researchers have created a unified method to track how building materials impact the environment across multiple lifecycles—addressing a major blind spot in renovation projects. The framework lets developers and policymakers measure real circularity gains and make smarter decisions about material reuse, potentially cutting waste and costs across billions in annual renovation spending.EN

Researchers discovered diverse microbial communities living in deep subsurface aquifers on minimal energy, yet they mysteriously stopped growing even when fed nutrients. The finding could reshape understanding of how microbes survive in extreme environments—with implications for geothermal energy, carbon storage, and predicting contamination in groundwater systems.EN

<p>Per- and polyfluoroalkyl substances (PFAS) are environmentally persistent chemicals associated with a wide range of adverse health effects, yet individual PFAS compounds may exert distinct toxicological...EN

Researchers created a predictive model for tracking a protected Swedish orchid using only publicly available forest data—no expensive field surveys needed. The approach achieved 88% accuracy and could help governments and land managers identify conservation priorities at a fraction of traditional costs.EN

Researchers have mapped exactly how much old-growth oak forest and grassland Europe's most vulnerable species need to survive — a critical tool for land managers and conservationists planning restoration. The findings could reshape how governments and private landowners prioritize habitat protection across fragmented landscapes.EN

Researchers are questioning whether climate science's "tipping point" concept can reliably predict social and economic upheaval. The debate matters because governments and businesses increasingly rely on tipping point models to forecast everything from supply chain collapse to political instability—yet the science underpinning those predictions remains deeply uncertain.EN

Scientists discovered living methane-producing microbes deep inside a terrestrial meteorite crater, generating gas from oil and other carbon sources. The finding could reshape understanding of Earth's deep subsurface ecosystem and has implications for subsurface resource management and modeling of early planetary atmospheres.EN

Researchers have identified why the Ganga River carries unusual isotopic signatures that alter ocean composition—findings that matter for understanding global weathering cycles and predicting how mountain rivers will respond to climate change. The work reveals how seasonal patterns and rock types upstream drive chemical changes that ripple downstream to the world's oceans.EN

A new study shows that Nepal's Himalayan rivers transport far more organic carbon to the ocean than previously measured, driven by seasonal patterns and mountain erosion. The finding challenges how scientists calculate the global carbon cycle and suggests a significant climate variable has been underestimated by policymakers and companies managing carbon budgets.EN

A new analysis of renewable energy systems for Swedish homes finds that ground source heat pumps and solar panels can deliver positive financial returns—but only under specific energy price and interest rate conditions. For property owners and real estate investors, the findings offer concrete guidance on renovation choices that balance climate goals with bottom-line economics.EN
