The Moon always shows the same face to the Earth. The reason is simple: it rotates on its axis in exactly the same time it takes to orbit our planet. Even though we cannot see it, we might assume the hidden side is similar to the one we know… but it is not, and we may now finally understand why.
Alien life in caves
When we think about the search for extraterrestrial life, we often imagine giant telescopes pointed at distant stars or rovers digging through Martian dust. But another surprising frontier in understanding how life might exist on other worlds lies beneath our feet.

But what is really happening in your body, and why does mint create such a vivid impression?
