Mining's effect on fish warrants better science-based policies

A new paper published in Science Advances synthesizes the impact of metal and coal mines on salmon and trout in northwestern North America, and highlights the need for more complete and transparent science to inform mining ...

Metal nanoparticles serves as plant growth regulators

Engineered nanomaterials (EMs) negatively or positively affect plant growth and development attributed to their physiochemical properties, application, and concentrations. Previous studies have shown that ferroferric oxide ...

Urban density strongly correlates with house sparrow health

House sparrows (Passer domesticus) have adapted to urban environments, which are changing and growing faster than ever before. A range of both biotic and abiotic factors—including habitat fragmentation, changing food availability, ...

Polluted land can be planted with flowers and tobacco

Zinnia (popular ornamental flowers) and tobacco adapt to copper in the soil. They accumulate heavy metal in the roots and limit the transport of copper to the aerial parts of the plant: stem, leaves, and beyond. At the same ...

Decontaminating heavy metal water using protein from plant waste

Scientists from Nanyang Technological University, Singapore (NTU Singapore), in collaboration with ETH Zurich, Switzerland (ETHZ), have created a membrane made from a waste by-product of vegetable oil manufacturing that can ...

Using microbrewery waste to synthesize carbon quantum dots

For a few years now, spent grain, the cereal residue from breweries, has been reused in animal feed. This material could also be used in nanotechnology. Professor Federico Rosei's team at the Institut national de la recherche ...

Catching microplastics with spider webs

Flies, mosquitoes, dust and even microplastics—spider webs capture whatever travels through the air. Researchers at the university have now for the first time tested if they can get an overview of plastic particles in the ...
