How atomic defects can program carbon quantum dots for future light-based technologies
How atomic defects can program carbon quantum dots for future light-based technologies
Carbon quantum dots (CQDs) are tiny carbon-based nanomaterials that have attracted increasing attention as environmentally friendly alternatives to conventional heavy-metal quantum dots. They are lightweight, photostable and potentially biocompatible, and their light absorption a
Breaking it down: how to limit the environmental impact of your body after death
From cardboard coffins and natural burials to water-based cremation, Australians are increasingly open to alternative farewells – but the key is to planChange by degrees offers life hacks and sustainable living tips each Saturday to help reduce your household’s carbon footprintGo
Burned-home soils showed uneven lead, arsenic contamination after Los Angeles wildfires
A chemical analysis of residential soils and ash around California homes burned by the Eaton and Palisades wildfires in early 2025 revealed wide variation in contamination by potentially harmful elements, including lead, according to a study published in Environmental Science and
Unintended climate trade-off: Clean air policies intensify urban heat island in humid citi
Researchers at the University of Hong Kong (HKU) have uncovered a critical, underrecognized trade-off in global environmental policies: While essential for improving public health, large-scale air pollution reductions are unintentionally intensifying warm-season surface urban hea

Great Barrier Reef drilling reveals repeated collapse, regrowth and migration since last i
An international expedition including University of Sydney researchers has pieced together the clearest picture yet of how the Great Barrier Reef responded to dramatic environmental change over the past 30,000 years. Multiple studies since the expedition more than 10 years ago ha
Deep-sea extremophile yields protein that forms super stable biofilm
Deep-sea extremophile yields protein that forms super stable biofilm
Scientists discovered a protein secreted by a deep-sea extremophile—an organism adapted to extreme environmental conditions—that self-assembles into a biofilm and is highly stable, boosting its potential for biomedical applications.
Tailored supplier strategies could cut emissions better than one-size-fits-all procurement
Tailored supplier strategies could cut emissions better than one-size-fits-all procurement
Companies hoping to reduce the environmental impact of their purchasing should tailor relationships with suppliers to different types of products rather than relying on a single procurement strategy, according to research published in the International Journal of Procurement Mana
How PFAS chain length influences environmental fate and water treatment
How PFAS chain length influences environmental fate and water treatment
Per- and polyfluoroalkyl substances (PFAS), often referred to as "forever chemicals," are among the most persistent contaminants found in water systems worldwide. Their strong carbon-fluorine bonds make them highly resistant to degradation, allowing them to remain in the environm

Spatially explicit population model can improve pesticide risk assessments in agricultural
A team of international scientists and risk assessment experts has developed a foundational blueprint for an innovative population model designed to improve environmental safety testing for agricultural pesticides. The tool, named APODEMUS (A POpulation Dynamical spatially Explic
New way to clean up environmental pollution using phage bioaugmentation
The ability of bacteria to remove pollutants from soil, water, mine waste and other environments could be supercharged by a "friendly" compatible virus, according to a study led by Flinders University. The new insights, published in Communications Biology, suggest phage virus bio
