Dhaka, June 28 -- Scientists have developed a new 'photosynthetic' material capable of absorbing carbon dioxide (CO2) from the atmosphere that could one day be used in buildings to combat climate change.

The innovative material was created by Swiss researchers using blue-green algae, known as cyanobacteria, which convert CO2, sunlight, and water into oxygen and sugars through photosynthesis.

Under specific nutrient conditions, the material can also transform CO2 into sturdy, eco-friendly construction components and solid minerals such as limestone. This provides permanent carbon storage while strengthening the material, the researchers said.

"Cyanobacteria are among the oldest life forms in the world. They are highly efficient at photo...
