You've probably seen the pyramidal diagram of Maslow’s hierarchy of needs. It's straightforward enough but, it might be a bit too subjective to really measure human needs.

We used to think having a distinct left and right brain was something unique to humans. But brain lateralization has now been found in everything from chickens to spiders! Does this change our theories for why some brains work that way?

Dating back more than 800 years, chocolate is deeply woven into the Indigenous history of Oaxaca, Mexico. TED Fellow Germán Santillán talks about his work reviving the Mixtec technique used to prepare this ancient delicacy by training a...

Have you ever moved? Some animals move too! And if an animal moves from one place to another for weather or food, it's called migration!

Hank introduces us to the "simplest" of the animals, complexity-wise: beginning with sponges (whose very inclusion in the list as "animals" has been called into question because they are so simple) and finishing with the most complex...

Interactions between species are what define ecological communities, and community ecology studies these interactions anywhere they take place. Although interspecies interactions are mostly competitive, competition is pretty dangerous,...

Hank brings us to the next level of ecological study with ecosystem ecology, which looks at how energy, nutrients, and materials are getting shuffled around within an ecosystem (a collection of living and nonliving things interacting in...
