Effects of ‘Fenton-like’ reactions of ferric oxalate on atmospheric oxidation processes and radiative forcing

The Fenton reaction is a chemical transition involving hydrogen peroxide (H 2 O 2 ) and the ferrous (iron) ion, which acts as a catalyst. This process is used to destroy hazardous contaminants in wastewater through oxidation. In the atmosphere,…

‘Vegan spider silk’ provides sustainable alternative to single-use plastics

Researchers have created a plant-based, sustainable, scalable material that could replace single-use plastics in many consumer products. The researchers, from the University of Cambridge, created a polymer film by mimicking the properties of spider silk, one of the strongest materials…

Bacteria-sized robots take on microplastics and win by breaking them down

Small pieces of plastic are everywhere, stretching from urban environments to pristine wilderness. Left to their own devices, it can take hundreds of years for them to degrade completely. Catalysts activated by sunlight could speed up the process, but getting…

Drone improves odor management in water treatment plants

The bad odors produced by the Waste Water Treatment Plants, known as WWTPs, have become a growing concern in the cities and towns that host these facilities and are considered by citizens to be the main cause of the perception…

Life stage differences shield ecological communities from collapse

A new study by ecologist André de Roos* shows that differences between juveniles and adults of the same species are crucial for the stability of complex ecological communities. The research, published in Proceedings of the National Academy of Sciences , represents a major…

Natural gas pipeline density higher overall in more vulnerable US counties

An analysis led by North Carolina State University researchers found counties with more socially vulnerable populations had a higher density of natural gas pipelines overall. The findings suggest counties that are more socially vulnerable are also at greater risk of…

Plastic in Galapagos seawater, beaches and animals

Plastic pollution has been found in seawater, on beaches and inside marine animals at the Galapagos Islands. A new study – by the University of Exeter, Galapagos Conservation Trust (GCT) and the Galapagos Science Center – found plastic in all…

Aquaculture turns biodiversity into uniformity along the coast of China

Fishery and aquaculture have given rise to an enormous uniformity in the diversity of bivalves along the more than 18,000 kilometer long Chinese coast, biologist He-Bo Peng and colleagues report in this month’s issue of Diversity and Distributions . Climate…

UNH research: Journey of PFAS in wastewater facilities highlights regulation challenges

DURHAM, N.H.–Researchers at the University of New Hampshire have conducted two of the first studies in New England to collectively show that toxic man-made chemicals called PFAS (per-and polyfluoroalkyl substances), found in everything from rugs to product packaging, end up…

Scientists find solution to measure harmful plastic particles in human sewage

Scientists have got up close and personal with human sewage to determine how best to measure hidden and potentially dangerous plastics. As the way microplastics are measured and counted varies from place to place, there is no agreed understanding of…

Food scraps get a bold new life

Tokyo, Japan – Most people don’t think much about the food scraps they throw away; however, investigators from the Institute of Industrial Science at The University of Tokyo have developed a new method to reduce food waste by recycling discarded…

As water sources become scarce, understanding emerging subsurface contaminants is key

USC researchers modeled complex subsurface water flow to help assess the risk of contaminants appearing in high, unsafe concentrations in variable water sources.

Grass replaces plastic in take-away food packaging

Soon, packaging for take-away foods might be completely based on local, sustainable materials instead of fossil-based products. In a new research project, a packaging solution based on upcycled grass fibres is being developed.

Russian wildfires and tropospheric ozone pollution over Northern Tibetan Plateau

Atmospheric ozone, which can regulate the amount of incoming ultraviolet radiation on the Earth’s surface, is important for the atmospheric environment and ecosystems. Tropospheric ozone, primarily originating from photochemical reactions, is the third most prominent greenhouse gas causing climate warming.…
