When giraffes speak, this scientist listens

Dr. Bonnie Baird can talk to animals — but she doesn’t chirp or growl. Instead, she carefully observes the behavior of the many species that call Woodland Park Zoo home. Though the creatures can't say how they feel, Bonnie uses data to translate their behavior into something we can understand and respond to. Are the giraffes happy? Do penguins get too hot? Can the sheep get a good night’s sleep? As the zoo’s animal welfare scientist, Baird answers these questions and more to help keep the animals healthy and content.

Why an octopus might think like an alien

To understand how aliens might think, Dominic Sivitilli went to the bottom of the sea to find the closest thing: an octopus. Its sophisticated nervous systems and sensitive suckers allow it to do incredible things like escape aquariums — but Sivitilli is learning how each of an octopus' eight arms might actually have a mind of its own. We don’t know yet if alien life exists. But if they do, they might think like an octopus.
