  "account": "In the heart of Pittsburgh, a city known for its steel industry, lies a brownfield site known as Hazelwood Green. Once a bustling hub of steel production, the site now stands as a testament to the resilience of life. Despite decades of pollution from the industrial era, the soil beneath Hazelwood Green has become a thriving ecosystem, teeming with billions of microorganisms. These microscopic inhabitants have not only adapted to the toxic environment but have also evolved to utilize the pollutants as a food source, effectively cleaning up the area. The transformation of Hazelwood Green from an industrial wasteland to a center for research and technology is a testament to the power of adaptation and evolution. By studying the microbial communities present in the soil, scientists can gain valuable insights into how these microorganisms have survived and thrived in the face of pollution, potentially paving the way for more effective strategies in cleaning up other brownfield sites around the world.",
  "summary": "Across Appalachia and the Rust Belt region, including throughout the city of Pittsburgh, former industrial sites are being transformed into new neighborhoods, research centers and technology hubs.",
