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.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
