Here's your inspiring story for the day: 17-year-old Samantha Garvey of Long Island moved into a homeless shelter with her family a year ago, but she still managed to become one of 300 semi-finalists for the annual Intel Science Talent Search. Garvey conducted a two and a half year study on aquatic ecosystems, which she describes in the video above. She says her family's situation "motivates me to do the work I do. I want a better life. I want a home. I want to show other people that even though you're going through something bad, there's a brighter side to everything."
