Researchers from Edith Cowan University say magnetite in Western Australia’s Pilbara iron ore could naturally generate hydrogen underground when hot water reacts with it; lab-like conditions and fracture access influence production, and injecting certain solutions could boost output, suggesting a potentially vast clean-energy resource for Australia and future export opportunities.
A reanalysis of Spirit rover measurements from 2004–2010 reveals widespread crystalline hematite and altered magnetite in Martian soil at Gusev Crater, signaling past water-rock interactions and suggesting Mars may have hosted more liquid water than previously thought; the finding, published in Interactions, highlights the ongoing value of reexamining archived mission data with new methods.
New research suggests a possible link between Alzheimer's disease and magnetite, a pollutant commonly found in vehicle exhaust and industrial processes. Studies on mice and human neuron cells exposed to magnetite, iron, and diesel hydrocarbons showed increased formation of amyloid brain plaques, behavioral changes, and immune responses associated with Alzheimer's. The findings, published in Environment International, indicate that air pollution may play a significant role in cognitive decline and dementia, shedding light on the environmental and lifestyle factors contributing to the development of Alzheimer's.
Harvard University-led research suggests that the building blocks of life may have started with the right kind of rocks. The researchers explain how life became molecularly right-handed, with RNA and the sugars that makeup DNA being right-handed molecules. By placing ribo-amino oxazoline (RAO) on magnetite surfaces, researchers could achieve 100% handedness of RAO crystallization, either left or right, depending on the spin-exchange interaction and degree of spin alignment at the active surface. The researchers say the effect is not likely to occur in particle solution contact like mud but rather on sedimentary rock surfaces.
