A groundbreaking study has provided new insights into the extensive impact of metal mining contamination on rivers and floodplains across the world, with an estimated 23 million people believed to be affected by potentially dangerous concentrations of toxic waste. The study used a new georeferenced global database of 185,000 metal mines compiled by the team alongside a combination of process-based modelling and empirical testing to predict the dispersal of mine waste in river systems to offer a comprehensive understanding of the environmental and health challenges associated with metal mining activities, examining both historical and active mining operations. With the rapid growth of metal mining crucial to the world making the transition to green energy, the study provides governments, mining companies, environmental regulators, and communities impacted by mining operations with a tool to understand the impacts of environmental impact of mining. Ultimately it is hoped that this will make it easier to mitigate the environmental effects of historical and present mining and help to minimise the impacts of future mining development on communities, while also protecting food and water security.

Almost 80% of plastic in the waste stream ends up in landfills or accumulates in the environment. Scientists have now developed a technology that converts a conventionally unrecyclable mixture of plastic waste into useful chemicals, presenting a new strategy in the toolkit to combat global plastic waste.

Sewage pollution, whether treated or untreated, was found to be the primary driver of increased nutrients, algae, and sewage fungus in rivers. Sewage discharge also radically altered plant, animal, and microbe communities, increasing the abundance of harmful species. Run-off from agriculture was also found to lower water quality and be particularly harmful for sensitive insect groups.

Using engineered microbes as microscopic factories has given the world steady sources of life-saving drugs, revolutionized the food industry, and allowed us to make sustainable versions of valuable chemicals previously made from petroleum. But behind each biomanufactured product on the market today is the investment of years of work and many millions of dollars in research and development funding. Scientists want to help the burgeoning industry reach new heights by accelerating and streamlining the process of engineering microbes to produce important compounds with commercial-ready efficiency.

Scientists have found a plant gene that drives the growth of root hairs, the tiny structures that help plants find water and nutrients in the soil. The gene, dubbed 'BUZZ,' causes faster-growing, denser webs of roots and may also determine how plants find and use nitrates, a prime source of nitrogen essential to plant growth. Nitrates are also used in fertilizers that can pollute the environment as runoff, and this genetic discovery could ultimately help plant scientists find ways to grow crops more sustainably.

Exposure to endocrine-disrupting chemicals like PFAS and phenols are implicated in hormone-mediated cancers of the breast, ovaries, skin and uterus. To learn more about the environmental exposures experienced by women who developed these cancers, researchers analyzed data from NHANES and found that women who reported having cancer had significantly higher levels of these chemicals in their bodies.

Researchers have genetically engineered a marine microorganism to break down plastic in salt water. Specifically, the modified organism can break down polyethylene terephthalate (PET), a plastic used in everything from water bottles to clothing that is a significant contributor to microplastic pollution in oceans.
