An eighteen-year-old high school student from Utah won the top prize in the Intel Science Talent Search in the United States. The winner received a computer and a scholarship for a college education.

More than 1,500students from across the country entered projects in the competition this year. Their research included chemistry, medicine, physics, mathematics, engineering, and computer science-almost every area of science.

Forty students were invited to Washington, D.C. for the final judging. A group of scientists judged them on their research abilities, critical thinking skills and creativity. The judges also questioned the students about scientific problems before deciding on the winners.

The top winner received 100,000 dollars for college. Shannon Babb of American Fork High School studied the water quality of tile Spanish Fork River in Utah for six years. She found that people have a harmful effect on the river through human activity, including agriculture. And she suggested ways to improve the water quality in the future. These include educating the public not to put household chemicals down the drains（下水道）, which lead to the river eventually.

Seventeen-year-old Yi Sun of the Hanker School in San Jose, California, earned the second place. He won a 75,000-dollar scholarship for new discoveries about a mathematical theory known as random walks. His work could help computer scientists and chemists. Yi Sun was born in China.

The third-place winner was also seventeen and born in China. Yuan “Chelsea” Zhang of Montgomery Blair High School in Rockville, Maryland, won a 50,000-dollar scholarship. She researched the molecular genetics（分子遗传学）of heart disease. Her findings could aid the development of new medicines.

The Intel Science Talent Search is the oldest science competition for high school students in the United States. It is 65 years old this year. Past winners have gone on to receive six Nobel prizes and other top honors in science and math.
