China Plans 770,000 km of Underground Utility Network Upgrades in Next Five Years

China's State Council has approved the "15th Five-Year Plan" for urban renewal, detailing plans to construct and renovate approximately 770,000 kilometers of underground utility networks. This initiative, requiring an investment of around 5 trillion yuan, is expected to stimulate GDP growth of 7.5 to 10 trillion yuan and create about 2.8 million jobs annually, significantly enhancing urban safety and resilience.

Vast underground fungal network mapped, stretching 110 quadrillion kilometers

Scientists have mapped a global network of microscopic fungi, arbuscular mycorrhizal fungi (AM fungi), stretching an estimated 110 quadrillion kilometers. These networks, often called the "wood wide web," support plant life by helping them absorb nutrients and water, store carbon, and maintain ecosystem health. The discovery highlights their crucial role in climate change mitigation and raises concerns about their decline in agricultural lands due to intensive farming practices.
