What are the significant contributions of Feng Zhang?

Feng Zhang helped scientists learn how to control and change genes, which are like instruction books inside our cells.

Imagine you're building a toy, and the instructions say "put red block on top," but it's actually blue. You want to fix that so your toy looks right. Feng Zhang helped create a special tool called CRISPR, which acts like a pair of scissors that can cut out the wrong part of the instruction book, the blue block, and replace it with the correct one, the red block.

With this tool, scientists can fix mistakes in genes just like you would fix a toy. They can also give new instructions to cells, helping them grow stronger or fight diseases. It's like giving your toy not only the right color but also superpowers!

This tool is used all over the world by scientists who want to understand and improve life, from making plants grow better to helping people stay healthy.
