A dirty and growing problem: Too few toilets
As the famous book says, everybody poops. That’s 7.8 billion people, worldwide. For the 2.4 billion with no toilet, the process can be complicated.

How to chill an object by sending its heat into space
Researchers have designed a device that can cool an object by radiating its energy into outer space. Think of it as a solar panel in reverse.

Sunlight + gold = steaming water (no boiling needed)
Nano-gold is the new black, at least when it comes to absorbing heat. When tiny gold particles get together, they become energy super-absorbers — turning them black.
