In a breakthrough that’s sure to stir up some controversy, Princeton researchers have reported that they have for the first time created artificial proteins from scratch in the lab that have enabled the growth of living cells. To achieve this, they created genetic sequences never seen in nature and produced completely synthetic proteins that were not modeled on living examples. They then inserted them into living bacteria, many of which thrived with their synthetic molecular machines.
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.
