California researchers have created a tissue-engineered small-scale small intestine in mice, a breakthrough for regenerative medicine and a step toward growing new intestines for humans. The process re-creates all the layers of cells that make up a functioning intestine.
There are certain areas of expertise that came naturally to us over the years: cars, space, aviation, and computers, to name a few. During the first half of the past century, we even provided practical features for scientifically-minded housewives. But children and babies? Not so much. Hence this compilation of PopSci's most dubious child-rearing technologies.
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.
