Young Plano scientist honored at the White House

A Plano Independent School District student has come up with a possible breakthrough in the battle against cancer. Williams High School junior Amy Chyao of Plano was among the young people hosted by President Obama on October 18, 2010 for the first-ever White House Science Fair. The event honored winners in a variety of science, technology, engineering and math competitions.

Amy Chyao developed a photosensitized for photodynamic therapy using light energy to activate a drug that kills cancer cells. "Photodynamic therapy has a lot of promise because it specifically only attacks cancer cells," she explained to President Obama. 

Amy Chyao isn't just a science whiz; she participated in the National Spelling Bee at age 13. That won her a trip to the White House in 2007, where she received a signed photo of first lady Laura Bush. (10/18/10)
