The Dumbo octopus is just one of the amazing creatures filmed by the most recent voyage of the E/V Nautilus.

Structures in some butterflies' wings are actually part of their ears.

Machines can translate some of the biological functions of plants into synthesizer sounds. But are these synthesized translations the same thing as music?

How does a plant — incapable of waving its arms or screaming — attract attention and spread its seed? By evolving a powerful stink or an attractive color, of course.
