Raji Doshi, 12, designed an algae system to reduce ocean acidity; now eyes $25,000 science prize

Raji Doshi (Image Credit: Young Scientist Lab) A 12-year-old student from Connecticut is drawing attention for tackling one of the world's biggest environmental challenges with an innovative science project. According to the Young Scientist Lab, Raji Doshi designed a project that proposes using algae and natural calcium (aragonite) buffers to help reduce CO₂-driven ocean acidification. Her innovative idea has earned her a place among this year's finalists, where she is now competing for the competition's $25,000 grand prize.A project inspired by a global environmental challengeOcean acidification is a major concern for scientists because the world's oceans absorb a significant amount of the carbon dioxide released into the atmosphere. As more carbon dioxide dissolves in seawater, the water becomes more acidic, making it harder for corals, shellfish and other marine organisms to build and maintain their shells and skeletons.According to her finalist profile on the Young Scientist Lab website, Raji's project explores whether combining algae with natural calcium (aragonite) buffers can help counter this process. The idea is based on the natural ability of algae to absorb carbon dioxid...
