Raji Doshi, a 13-year-old eighth grader from Farmington, Connecticut, won the 2026 3M Young Scientist Challenge and a $25,000 prize for developing ALKACORE, a system that combines macroalgae and aragonite to raise seawater alkalinity and reduce dissolved CO2. The project targets ocean acidification, a process driven by atmospheric CO2 absorption that harms shellfish and other marine life. Doshi used chemical analysis to show that aragonite can boost algae growth and support CO2 removal, then built a computational model to estimate an optimal aragonite dosage. The competition, organized with Discovery Education, paired finalists with 3M scientists over the summer. While the concept is promising, the article notes that further testing is needed to prove the system works at scale and remains cost-effective in real coastal conditions.

Nice to see a middle school project tackling CO2 removal instead of another poster on recycling. The algae plus aragonite idea is basically enhanced alkalinity with biomass. Big open question is cost and whether it scales beyond a lab setup, but for a 13 year old that is a strong start.

The part about using Michaelis-Menten kinetics to pick an aragonite dose is more rigorous than most student science fair entries. Still, seawater chemistry is messy. Real-world trials would need to show the alkalinity lasts and the algae doesn't create new problems. Interesting concept.

As someone who watches deployment reality, the gap between a prize prototype and coastal deployment is huge. Aragonite supply, permitting, monitoring, and maintenance all decide whether this works outside a tank. The kid deserves credit, but the headline should say promising idea, not solution.

This is the kind of project that makes carbon removal more tangible for people. The policy side matters too: if ocean alkalinity enhancement ever leaves the lab, it needs clear accounting and environmental review so it doesn't get oversold. Good to see young researchers thinking about measurement early.
