India has installed its first "Liquid Tree" — a water-filled structure packed with microalgae that absorb CO₂ and release oxygen through photosynthesis — functioning as a compact, even more efficient air-purifying alternative for dense urban areas where planting real trees is difficult. The harvested algae can also be used as plant fertilizer, adding a circular-economy dimension to the system.

Africa warms at twice the global average, and excessive heat can bring health problems. A simple solution is showing great effect: a coat of heat-reflective white paint on a rooftop can lower indoor temperatures enough to protect sleep and reduce the risk of serious illness. A trial across four communities in South Africa and Ghana is already showing residents feeling cooler — with full health results on the way.
