Today, President Obama welcomed more than 100 students from across the country for the second annual White House Science Fair, an opportunity that gave the students a chance to show off their research projects. Angela Zhang, a local high school senior who took the top prize at the Siemens Competition in Math, Science and Technology back in December, was among the participants. Zhang, who was mentored by Stanford radiologist Zhen Cheng, PhD, won a $100,000 scholarship for what one scientist called "a Swiss army knife for cancer treatment" -- a multifunctional nanoparticle that combines treatment and imaging in a single unit. In the video above, she describes her work to CBS News.
