A new study from Tufts University reveals that honey bees fine-tune their nutrient-seeking behavior based on the seasonality of their floral diet. Bees forage for minerals like calcium, magnesium, and potassium in water sources that reflect what's lacking in their pollen-based diet.
Research by University of Sussex professor Constantin Blome found that industry collaboration and consumer pressure can make a big impact in the global drive to stop profits from mineral trade falling into the hands of armed groups. Simple measures such as sharing lists of certified smelters and refineries can help.
A report by Queen's University political researcher Nathan Andrews finds that EITI countries did not perform better than non-EITI countries, despite disclosure of tax and royalty payments. The researchers speculate that the initiative's limited scope and voluntary nature hindered its effectiveness in reversing the resource curse.
Scientists from the University of Exeter will lead a four-year €5.4 million project to discover essential raw materials and minerals in Europe. The team aims to use advanced techniques to expose previously unknown underground resources for high-tech products.
A new study examines trade flows of 71 mineral commodities between 107 countries and finds that regional shortages of essential minerals can lead to cascading shocks and instabilities in the global market. The research proposes policy measures, such as commodity risk taxes, to create more stable markets.
A Norwegian study reveals that fish farming consumes a significant amount of phosphorus, with the industry generating 9,000 tonnes of emissions annually. The researchers propose reusing this waste phosphorus to create new products and reduce pollution, offering potential solutions for Norway's aquaculture industry.
A new study by Alexander Simms and colleagues reveals that uplift rates across the Pacific Coast have been overestimated by an average of 40%, implying a slower rate of shoreline rise. This finding has important implications for coastal management, including earthquake hazards and sea-level rise impacts.
A new study finds that EU consumers waste an average of 123 kg per capita annually, equivalent to 16% of consumed food. The majority of this waste is avoidable, with vegetables, fruit, and cereals being the most wasted due to shorter shelf-life and over-purchasing.
The dominant approach to hip fracture prevention is neither viable nor cost-effective, according to experts. The focus on drug treatment overlooks feasible alternative strategies like physical activity, which can have little to do with osteoporosis but are often overlooked.
Compromise solutions are needed when building roads through sensitive tropical and subtropical areas, say experts. The authors propose four measures to mitigate tensions between roads and protected areas, including early involvement of infrastructure engineers and natural resource managers.
The deep sea provides essential services to humans, including nutrient-rich fish stocks, waste management, and reserves of oil, gas, precious metals, and rare minerals. Its unique ecosystems also host life forms with potential for new antibiotics and anti-cancer chemicals.
A University of Alberta team has discovered a water-rich mineral called ringwoodite, containing 1.5% water by weight, deep beneath the Earth's crust. This finding confirms scientific theories about massive volumes of water trapped between 410-660 km below the surface.
A team of researchers found that microbes engage in market-like behaviors, including comparing bids for commodities, hoarding resources, and eliminating competitors. This discovery has implications for understanding microbial interactions and could lead to new approaches in social microbiology.
The Geological Society of America has published three Special Papers in celebration of its 125th anniversary, showcasing advances in geosciences, technologies, and societal impacts. The volumes highlight the past 50 years' progress, from understanding plate tectonics to exploring space and developing new technologies.
A new Australian study uses a novel modelling tool to calculate the 'material footprint' of 186 countries over two decades, revealing that pressures on raw materials do not decline with economic growth. The results confirm that decoupling of natural resources from economic growth has been exaggerated.
Raimon Tolosana-Delgado's mathematical models help understand rock formation and sediment development, crucial for predicting raw material locations. The prize recognizes his work on developing general models applicable to various raw materials, which could improve exploration and extraction efficiency.
Researchers found high concentrations of gold in termite mounds, indicating a larger deposit underneath. These insects bring up small particles containing gold from the deposit's fingerprint and stockpile it in their mounds.
Researchers at Aalto University estimate that halving food losses globally could provide enough food for an additional 1 billion people, saving 614 kilocalories per person daily. This reduction would require efficient use of resources such as clean water and fertilizers.
Yale researchers developed a methodology to evaluate the importance of scarce metals using supply risk, environmental implications, and vulnerability analysis. The new approach provides a standardized framework for corporations and national governments to inform strategic decision-making around resource use.
