The abundant salt in the atmosphere above the Amazon basin has long been attributed to the Atlantic Ocean. But now, using the Advanced Light Source, scientists have found that much of it originates much more locally: fungal spores in the rainforest. Pinpointing the origin will improve climate models and understanding of rainforest ecosystems. Read more »
Meteorites Suggest Galvanic Origins for Martian Organic Carbon
Nanoscale analyses of Martian meteorites suggest that organic carbon on Mars may have been formed by electrochemical reactions between briny liquids and volcanic minerals, as might occur in a galvanic cell. The study has major implications for astrobiology and could also shed light on the reactions that led to life on the early Earth. Read more »
