Learn to cure cancer

A vaccine for cancer is in the works.

Lauren Landry and Chloe Tomblin are the scientists. They look in freezers(冰柜) for bacteria to use in the research. This research has its limitations—mostly because their lab is in a high school.

But Lauren, 16, and Chloe,17 both students are Western Reserve Academy in the US, aren’t put off by the difficulties they face in their cancer immunology(免疫学) class.

“I hope we get to the point where we can get to a vaccine and write a paper,” Lauren said.

Both conduct research into how to engage the immune system in stopping cancer from forming.

Though the lab is in a high school, they don’t use textbooks. The aim is to conduct real cancer research, either by testing the effects of substances on cancer cells or developing vaccines to target the growth of those harmful cells.

The idea for the class came from Robert Aguilar, who has taught at the private school for many years. Students spend the first year learning research techniques. In the second year, students swap(调换) their blue lab coats for white ones. By this stage they are well into their research projects.

“If first-years need any help, they can feel free to ask second-year students,” Aguilar said.

Students form groups to conduct their research. One pair of students has researched the effect of capsaicin(辣椒素) on killing cancer cells. Another has tested the effect of caffeine(咖啡因) on the growth rate of breast cancer(乳腺癌) cells.

But few students get to the point in their research of experimentation with mice, Aguilar said. Lauren and Chloe hope that they can make decent progress in their work.

“We know they’re going to be used for good,” Lauren said. “If it does or doesn’t work, it still has a huge impact.”

Aguilar teaches the students that even research that doesn’t work still contributes to science in some way. He tells students that “the best part of research is failing a lot”.
