New soil test could reveal how soil microbes help feed plants
Scientists have streamlined a method for measuring DNA-bound phosphorus in soil, making it cheaper and easier while preserving its accuracy. The technique could reveal how soil microbes help recycle phosphorus and ultimately support more sustainable fertilizer and nutrient management.
1.7-billion-year-old fossils reveal a crucial clue to the rise of complex life
Scientists studying ancient Australian rocks uncovered more than 12,000 fossils from some of the oldest known eukaryotes on Earth. These early complex cells lived in settings ranging from coastal mudflats to the open sea, but only where oxygen was available. Oxygen-free environments contained simpler microbes instead. The findings strengthen the idea that oxygen played a crucial role in the emergence of complex life.
