He can't drive himself to work, but his latest research is changing the way doctors train. Some kids are making big marks on medicine.

Fourteen-year-old Tony Hansberry wants to practice medicine.

"I've always had a passion for medicine," Tony told Ivanhoe.

The high school freshman designed a study that’s now benefiting medical students twice his age.

"The project I did was, basically, the comparison of novel laparoscopic instruments in doing a hysterectomy repair," Tony explained.

He found a specialized sewing tool is quicker than a traditional needle for a particular kind of minimally invasive surgery.

Now, Brent E. Seibel, M.D., Assistant Professor at the University of Florida College of Medicine in Jacksonville, Fla., wants to make a change to his syllabus.

"I didn’t include that device as one of the stations or steps we use in the simulation center, but now I will," Dr. Seibel told Ivanhoe.

What's this whiz kid's secret to success? His parents say a rigorous study schedule with some fun mixed in.

"Being able to capture a child and understand what a child's interests might be is important," Tony's father told Ivanhoe.

Educators are using high school internships and other programs to boost the number of young people interested in medicine. It’s projected the doctor deficit could reach 200,000 by the year 2020.

Duke University student Josh Sommer isn’t yet out of college, but he’s also making a big mark on medicine.

"When you’re 18 years old, and you say, 'OK, I have a disease. The average survival is seven years,' you start thinking, what am I going to do in the next five years?" Josh told Ivanhoe.

While a rare bone cancer threatens his life, he works alongside scientists to find a cure. He also runs the Chordoma Foundation -- raising money for research and awareness.

Proof that age doesn't matter if you want to change the face of medicine.

Tony attends a special medical magnet school that allows him to take advanced classes in medicine. Experts advise kids as young as 10 who are interested in a profession to seek out internships and shadowing positions.
