Fiddler Crabs Are Found to Hoover Up and Break Down Microplastic Particles Microplastic particles were found to be ingested and fragmented by fiddler crabs in polluted mangroves. This behavioral adaptation was studied by scientists. Study Setting and Goals First, polluted mangrove forests in Turbo, Colombia were selected as field sites.Then, fluorescent polyethylene microplastics were introduced…

Hydrogen Emissions Are Indirectly Heating Earth and Supercharging Methane New research shows that emissions of hydrogen have risen since 1990 and now amplify climate warming through effects on methane, the potent greenhouse gas. Hydrogen’s Indirect Climate Role First, the global hydrogen budget was comprehensively assessed by an international consortium of scientists.Then, hydrogen was found to…

Fine Air Pollution Particles Linked to Early Immune Changes That Precede Autoimmune Disease A new study by McGill University researchers has found that fine particulate air pollution — tiny airborne particles small enough to enter the bloodstream — is associated with early changes in the immune system that often occur before the onset of autoimmune…

Wildfires Reshape Forest Soils for Decades, Göttingen Research Reveals An international research team led by the University of Göttingen has found that wildfires don’t just burn vegetation — they fundamentally alter soil structure, chemistry, and nutrient cycles in forest ecosystems for more than a decade after the flames have gone. This long-term imprint on soil…

Most U.S. Rivers Lack Adequate Protection From Human Impacts, New Study Shows A first-of-its-kind assessment of river protections across the United States reveals a startling conservation gap: the vast majority of U.S. rivers — including waterways that provide drinking water, habitat, and recreation — have little to no formal protections against human activities such as…

Global Aviation Emissions Could Be Halved by Maximising Efficiency, Oxford Study Shows A new study co-led by the University of Oxford suggests that global aviation emissions could be reduced by 50–75% by focusing on operational efficiency — without cutting flights or waiting for future fuels. Published in Nature Communications Earth & Environment, the research analysed…

Wildfires and Prescribed Burns May Emit 21% More Air Pollution Than Previously Estimated New research published in Environmental Science & Technology (American Chemical Society) shows that wildfires and prescribed burns emit significantly more air-polluting organic compounds than earlier estimates suggested — especially intermediate- and semi-volatile organic compounds that readily form harmful fine particles in the…

After Years of Plastic Cleanup, Coastal Marine Ecosystems Show Signs of Recovery Decades of persistent coastal cleanup efforts — from removing trash by hand to implementing plastic bans and improving waste management — are now yielding signs of ecological recovery in shorelines and nearshore waters. Recent observations from multiple regions show that when the flow…
