Scientists have decoded the seismic fingerprints of Iceland's catastrophic glacier outburst floods, discovering repeating earthquake patterns that could help predict when massive water surges will hit downstream infrastructure. The findings offer a new early-warning tool for communities and industries dependent on glacier-fed rivers, where floods can cause billions in damage.EN

Researchers are bringing software design expertise to regenerative agriculture, arguing that sustainable farming requires systematic engineering approaches. The work opens a new frontier for tech professionals to address food security and soil health — areas where traditional design methods have rarely been applied.EN

Researchers reviewed 49 integrated models designed to predict and control nutrient pollution in lakes and reservoirs, finding a patchwork of disconnected tools with uneven global coverage. The analysis reveals a critical gap: most regions lack locally-adapted models to guide water infrastructure investments and pollution control strategies.EN

Geologists traced ancient sand grains in Sweden back to a mountain range that existed 550 million years ago, revealing how sediment traveled thousands of kilometers across a primordial landscape. The finding rewrites understanding of how Baltica—a major continental plate—was shaped and could inform predictions about sediment transport in modern coastal systems facing climate pressures.EN

A new study shows that bisphenol AF, a common replacement for the banned chemical BPA, impairs how muscle cells take up glucose and respond to insulin—potentially explaining why exposure increases type 2 diabetes risk in humans. The finding suggests regulators and manufacturers may need to reassess whether BPA alternatives are genuinely safer.EN

Researchers have for the first time isolated and measured pollution from leisure boat engines in Swedish coastal waters, finding that recreational boating accounts for up to 40% of harmful chemical concentrations in some areas. The discovery has implications for environmental regulation, coastal tourism management, and companies operating in or near heavily trafficked marine areas.EN

A new study finds that players who engage with environmental themes in games develop empathy that translates into real-world concern about sustainability. The finding suggests game design could be a powerful tool for overcoming what researchers call our "crisis of imagination"—the inability to envision radically different, sustainable futures.EN

New research shows Congo's rainforest supplies 10-20% of water for agriculture across Sub-Saharan Africa, with some regions dependent on it for over 40% of their rainfall. As deforestation and climate change accelerate, this hidden dependency creates urgent risks for food security and agricultural investment across the continent.EN

Phthalates—ubiquitous additives in soft plastics, cosmetics, and personal care products—alter gene expression in human endometrial cells in ways that could affect fertility and pregnancy. The finding, based on real-world exposure levels, signals potential reproductive risks that regulators and manufacturers may need to address.EN

A study of Swedish principals reveals practical methods for embedding environmental consciousness into school culture, moving beyond self-interest to collective wellbeing. As educators worldwide grapple with climate literacy and sustainability mandates, these findings show how institutional leadership can drive the mindset changes needed to create systemic environmental action.EN

Researchers have directly observed previously hidden molecular intermediates in a promising catalytic process that converts carbon dioxide into carbon monoxide—a building block for synthetic fuels and chemicals. The discovery clarifies how a rhenium-based catalyst works, potentially unlocking more efficient industrial pathways to turn captured CO2 into valuable products rather than waste.EN

Bangladeshi mothers exposed to air pollutants during pregnancy had daughters who reached puberty earlier than expected, according to new research. The finding raises concerns about how industrial emissions and vehicle exhaust may disrupt child development in vulnerable populations—and could inform environmental health standards globally.EN

Researchers discovered that five persistent pollutants—including DDT and PCBs—disrupt how ovarian cells manage energy, potentially explaining why exposed women struggle with fertility. The finding raises urgent questions for regulators and health officials about legacy chemicals still circulating in the environment decades after bans.EN

New research shows that the way underwater melting occurs at glacier edges dramatically shifts how fast glaciers calve and move — yet scientists lack consensus on which melting models to use. For coastal communities and infrastructure planners relying on sea-level rise projections, this uncertainty could mean significantly underestimating or overestimating future ice loss from Arctic glaciers like Kronebreen in Svalbard.EN

A new textbook synthesizing knowledge from 50+ experts provides the first comprehensive reference on alpine bird ecology as climate change reshapes mountain ecosystems. For conservation organizations, government agencies, and land managers, the resource offers evidence-based strategies for protecting species increasingly threatened by warming temperatures and habitat loss.EN

Researchers have developed small organic compounds that can replace expensive metals in devices that convert sunlight into hydrogen fuel and capture carbon dioxide. The breakthrough could lower the cost of solar fuel technology and accelerate its commercial deployment across industries seeking to decarbonize.EN

Researchers have cracked a persistent problem in solar technology: extracting useful electrons from light without triggering competing thermal reactions that waste energy. By engineering a specialized electrode and pulsing light rather than shining it continuously, they've demonstrated a pathway to more efficient light-driven chemical reactions—a breakthrough with implications for cleaner hydrogen production and industrial synthesis.EN

When COVID-19 lockdowns cut traffic and industrial activity in Sweden, air pollution dropped sharply—and a new study quantifies what permanently cleaner air could achieve. If such improvements held, the region could prevent 1-3% of premature deaths annually while slashing child bronchitis cases by 4%. The finding offers concrete health economics data for regulators and businesses weighing pollution reduction investments.EN

Researchers have quantified how severe geomagnetic storms could damage Sweden's electrical infrastructure over the next 10, 50, and 100 years. The findings give utilities and grid operators concrete data to plan infrastructure upgrades and insurance strategies against a hazard that has already knocked out transformers across the country.EN

European sprat populations show limited genetic diversity despite living in vastly different waters—from oceans to the Baltic Sea. The finding challenges assumptions about how fish adapt to environmental stress and could force fisheries regulators to rethink stock assessments that currently treat some populations as interchangeable.EN

Researchers have mapped exactly how lignin—a waste byproduct from paper mills—captures pollutants from water, finding that hydrogen bonding accounts for 61% of the cleaning power. The discovery could unlock cheaper, faster ways to turn industrial waste into effective water treatment materials, a growing market as regulations on water quality tighten globally.EN

Europe's major cancer research organization is restructuring operations to become environmentally sustainable following COVID-19 disruptions. The shift signals growing pressure on scientific institutions to align with climate goals—a trend likely to reshape funding priorities and operational standards across the academic research sector.EN

Nearly a third of Sweden's public swimming pools exceed safe airborne trichloramine levels, a toxic chlorine byproduct that irritates eyes and lungs.
