In the name of Science

When I first laid eyes on this photo, I thought: Kawaii! Cute leh!

Then I read on. This little white mouse's spine was deliberately injured, then injected with blue food colouring (explains the blue) and observed for effects of the dye on treating spinal cord injuries. The mouse was killed 6 weeks after this experiment for further examination. Well, the brave sacrifice of this little mouse did show scientists that blue dye do have some positive effects on spinal cord trauma and the colour goes off in a week. Will this work for humans in future? Or will it be red, yellow or green food colouring that does the final magic?

I suddenly shudder at what we do in the name of science. For full report of this article, it's at National Geographic News
