In this instance I just happen to think this is rather cool.
Using bio-luminescence as a tracker to figure out ways to help people with genetic disorders and diseases. Looks rather freaky though... red and green glowing animals under black light.
I just think it's neat the creativity in the thinking the scientists must have... to think of using the luminescence of jellyfish as a way of marking genes, so you can track how they are working in a body, so you can help people live better lives.
And it's fascinating to me how God created the world in such a way that one part can be useful and helpful to another part. We have to take that seriously. Treating the animals under our care with respect and concern for their overall well-being eh?
