  "account": "Microplastics pose a growing threat to soil and water, harming ecosystems and entering the food chain. Researchers in the Czech Republic have developed microscopic robots capable of removing these tiny plastic particles from both soil and water environments. Using magnetic nickel nanoparticles, these microbots can spin, tumble, and navigate through liquid and soil, actively binding to and extracting microplastics. In lab tests, the microrobots removed 94% of polystyrene and 89% of PET plastic particles from water in just an hour, and achieved 81% and 72% removal rates for polystyrene and PET in soil. While promising, further field trials and addressing potential risks such as metal ion leaching and incomplete retrieval are needed before widespread implementation. This innovative microrobotic platform offers a sustainable solution for active decontamination of both aquatic and terrestrial ecosystems.",
  "summary": "Microplastics, which are plastic particles under 5 millimeters, are a major and growing threat in both soil and water. They damage soil fertility, disrupt nutrient cycling, harm aquatic and terrestrial life, and can move through the food chain. That makes cleaning them up an urgent priority.",
