“Calif. teen takes $100K national science prize”
WASHINGTON (AP) — A high school student from California won a $100,000
scholarship Monday for research that created a tiny particle she likened to
a "Swiss army knife of cancer treatments" because of its precision in
targeting cancer tumors.
Angela Zhang, 17, of Cupertino, Calif., won top individual honors at the
Siemens Foundation's annual high school science competition, which announced
winners in Washington. Top team honors went to a pair of students from Oak
Ridge, Tenn., for their research using gaming technology to analyze the
motion involved in walking. Cassee Cain and Ziyuan Liu, both 17, will share
a $100,000 scholarship.
Six individuals and six teams were competing for the awards, which are in
their 13th year. Zhang, the only female individual finalist, said her
research was in part motivated by her family. Her great grandfather had
liver cancer and her grandfather died of lung cancer when she was in seventh
grade.
"I asked, 'Why does this happen. Why does cancer cause death? What are we
doing to fix this and what can I do to help,'" said the Monta Vista High
School senior.
Zhang said the particle she designed improves on current cancer treatments
because it delivers a drug directly to tumor cells and doesn't affect
healthy cells around it. The particle is also able to release a drug when
activated by a laser. The idea is still years away from being used in
patients, however. Zhang says it could take 25 years between clinical trials
and other steps before her research is helping patients.
The team winners, Cain and Liu, got their inspiration from video game
technology normally used to track a person's movements for dance, sport and
fitness games. The pair of seniors from Oak Ridge High School developed
software that uses the technology to analyze the way a person walks. They
hope their software can ultimately be used to help people who wear
prosthetic limbs improve their walk. Currently, people who have prosthetic
limbs generally have to travel to labs to get that kind of help, but Cain
and Liu say that because their software uses readily available technology it
could be more widely used and also taken to developing countries.
"Anything that has a joint we can track, really, just depending on what we'
re interested in or what the doctor is interested in," said Cain, who is
also the drum major in her high school marching band and a costume designer
for the drama club.
The runners-up in the team and individual competitions went home with $50,
000 scholarships. Second place in the individual competition was Brian Kim
of New York, who studied ways to more efficiently pack objects into a space.
The second-place team winners were Edgar Wang, Wayne Shu and Justin Yuan of
Troy, Mich., whose research could help treat Alzheimer's disease and stroke. |
