We are a team of doctors and world top people who work in the hospital. We want to do something new to help people get better quicker and more easily, so they can live a longer and happy life. 

To do this, we have a deeper look at blood and try the new things out first on cells and then on humans. Another group of women and men make some kind of light that can be followed within the human body to track these mad cells. This light can be seen by the doctors and then used to help make people feel better.
