We didn’t want to write about it. Seriously, we didn’t. Sure, Michael Phelps has digital technology, the 24-hour news cycle and precision blown glass to blame for his plight but we’re better than that.* But when US Swimming went and suspended Phelps for two months for, ultimately, acting his age, we felt compelled to write something. The 'Science' part of Popular Science restricts us from condemning the insanity of the punishment (note, however, they did nothing following his 2003 DUI).

Our most popular and addictive drugs come from plant toxins; caffeine, tobacco, cannabis, cocaine, heroin, are all derived from what are supposed to be poisons. These toxins were developed by plants to ward off herbivores who would otherwise eat them. So why is it that we not only tolerate them, but have found ourselves in a position of craving them, sometimes desperately? It is a paradox at which researchers are taking a fresh look.
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.
