The roundworm Caenorhabditis elegans has been a staple of biology research for almost 50 years, but, thanks to advances in molecular-biology techniques, scientists are just now able to study how multiple genes (C. elegans has 20,470 genes in its genome) act in concert to produce complex organs. In an anesthetized worm’s healthy gonad, eggs start out as tiny cells [upper right corner] and snake around counterclockwise as they mature.
Simply put, pills are stupid. They don't know what's going on in your body when you take them, they don't know the optimal time to release their medication, and they certainly can't vary their own dosage levels on the fly.
