For me, octopuses strike the perfect balance of cool and cuddly. But would I want one to rescue me? Scientists in Israel have captured the first slow-motion video of an octopus crawling, which could help us design robots flexible enough to squeeze through collapsed buildings as part of rescue operations.

I love this example of how nature can inform technology. Evolution is ruthless in selecting the most efficient way of doing things, and we should actively study the natural world to find solutions for human problems.
