2 Americans, German-American win Nobel in medicine 2013

Two Americans and a German-American won the Nobel Prize in medicine on Monday for discovering how key substances are transported within cells, a process involved in such important activities as brain cell communication and the release of insulin.

This is the first Nobel Prize been announced this year. They said as they research, a lot of people thought they are just crazy.

They spend a lot of time and energy to do the research. I hope later on those will be the finding the cures for some certain diseases.
