In many places, including the U.S., up to 25% of potable household water is used to flush the toilet. Contrast this with the estimate that only about 5% of our potable water is used for drinking, and one has to wonder (as we do) if there isn't a better approach in a world of increasing drought, [...]

The next frontier of at-home health tracking is flush with data: the toilet. Researchers and companies are developing high-tech toilets that go beyond adding smart speakers or a heated seat. These smart facilities are designed to look out for signs of gastrointestinal disease, monitor blood pressure or tell you that you need to eat more fish, all from the comfort of your personal throne.

A flying toilet might sound cool. You could imagine a hovercraft into which you can pee or poop. But the reality is a lot less fun. A flying toilet is a plastic bag into which someone relieves himself. Then? It’s thrown away. Pretty gross, right? So why would anyone do that? Because a great many [...]
