13-Year-old Raji Doshi named America's Top Young Scientist for inventing an algae-aragonite alkalinity system to reduce CO2-driven ocean acidification

Raji spent the summer competing against nine other finalists and ultimately secured the win during final Challenge events at 3M global headquarters in
Raji's project, Engineering a Novel Durable Algae-Aragonite Alkalinity System to Reduce CO2-Driven Ocean Acidification, tests whether macroalgae cultivation paired with natural calcium carbonate buffers could create a durable, low-cost system for reducing coastal acidification, a growing threat to marine ecosystems. The solution reflects the 3M Young Scientist Challenge's focus on encouraging middle school students to think creatively, apply the power of STEM, and develop real-world solutions that can make a meaningful impact. Through carbonite chemistry analysis, Raji demonstrated the efficacy of aragonite in increasing algae biomass, removing carbon dioxide, and substantially lowering dissolved carbon dioxide. She also developed a Michaelis-Menten computational model to identify an optimal aragonite dose, a step toward making climate solutions more practical for coastal communities.
"The 3M Young Scientist Challenge highlights the incredible potential of young people to tackle real-world challenges through science," said
Each 3M Young Scientist Challenge finalist is paired with a 3M scientist who mentors and works with them one-on-one over the summer to transform their ideas from concept to prototype. This year's winner was paired with
"Raji's project reminds us that when you're passionate about something, you can use that interest to change the world," said Isabelle. "She loves collecting seashells and was distressed that ocean acidification is starting to damage the seashells and the creatures that live inside them. It was that passion that led her to create ALKACORE to address the ocean acidification issue."

"When students have the support to follow their curiosity, their ideas can grow into real-world innovation," said
Now in its 19th year, the 3M Young Scientist Challenge continues to inspire and challenge middle school students to think creatively and apply the power of STEM to develop real-world solutions. Former America's Top Young Scientists have given TED Talks, filed patents, founded nonprofits, and made the
The award-winning competition supplements the 3M and Discovery Education program Young Scientist Lab, which provides no-cost dynamic digital resources for students, teachers, and families to explore, transform, and innovate the world around them. All the resources are also available on Discovery Education Experience, the essential companion for engaged PreK-12 classrooms.
