God gave lobsters hard outer armor to protect them from predators and a segmented tail to propel them quickly through the water. So far, engineers have yet to develop a material as flexible, yet sturdy, as the one God designed for the lobster tail. Massachusetts Institute of Technology (MIT) researchers recently set up a series of experiments to explore how the translucent membrane that covers lobster tail joints allows the creature flexibility without leaving it vulnerable.

Since Chinese scientist He Jiankui announced in November that he used the CRISPR gene-editing tool to produce the first genetically altered human babies, international leaders have discussed ways to tighten genome-editing guidelines. But if a rogue scientist in China could sidestep his country’s regulations, what safeguards can stop amateur do-it-yourselfers?
