How did this scientist make the invisible visable, using bioluminescence?
The first 4 minutes of this video are very interesting. The next part is much more complicated!

PHENYLKETONURIA (PKU)
Phenylketonuria (PKU) is a rare metabolic disorder which occurs in people who are missing an enzyme that the body needs to use phenylalanine. Phenylalanine is an essential amino acid (a building block for proteins in the body), meaning the body needs it for health but cannot make it. You have to get it from food. When someone does not have the enzyme, that causes high levels of phenylalanine to build up. If it is not treated before 3 weeks of age, PKU can cause severe, irreversible mental retardation. In the United States, newborns are tested for PKU during the first 48 - 72 hours of life. People with PKU must eat a diet that avoids phenylalanine and take tyrosine supplements to have optimum brain development and growth.
