PHOENIX (NEWS CENTER) — Maine high schoolers competed at the Intel International Science & Engineering Fair in Phoenix this week.

Demetri Maxim, a senior at Gould Academy, won first place in his category for his work in developing a way to grow kidney cells from skin tissue. He was awarded three other awards Thursday night.

Paige Brown, a senior at Bangor High School, also won first place in her category for designing a method for removing the pollutant phosphorus from stormwater.

One of Paige's schoolmates at Bangor High, Sydney McDonald, also competed at the fair. She's developed an idea for artificial muscles powered by the body's own electrical current.

Congratulations to all three.
