This paper presents a Graph Attention Network (GAT) approach to model spatial dependencies in soil samples for predicting microplastics and organic matter, achieving high R² values but limited cross-validation generalization due to small sample size.
Researchers found that sterilized soil continues to consume oxygen and release carbon dioxide for years, suggesting metabolic-like reactions can occur outside living cells. The finding, published in Science Advances, may imply that some biochemical processes predate life on Earth.
