Scientists invent photosynthetic 'living' material that sucks CO2 out of the atmosphere

Swiss scientists have created a "living" material with blue-green algae that could help fight climate change. The photosynthetic material converts CO2, sunlight, and water into oxygen, sugars, and solid carbonate minerals, strengthening itself over time. In tests, it efficiently sequestered CO2 for 400 days, storing about 26 mg of CO2 per gram. Researchers propose using it as a building facade coating to absorb atmospheric CO2, with potential applications in architecture and carbon sequestration.
