This week on Curious-ish, Greta takes science to the streets of Chapman University where she asks the campus what they are curious about in the world. A double-major physics and philosophy student, Julianna, asks the question “why don’t we see the color blue often in nature?”. After Julianna gives the question her best shot with her own answer, Greta takes a deep dive into all things blue in nature. From sea life, to birds, to plants, to even human eyes, the color blue is rarely found in our natural environment and when it is, most of the time it isn’t actually blue at all! Finding an actual blue pigment in nature is very rare and only a couple animals have the ability to produce a blue pigment within their body. Greta uncovers what these creatures are and how they do it with the help of plenty of research from many different sources, all cited below for you listeners to browse! Besides the color blue, Greta answers questions from Curious-ish listeners regarding bird migration, how our personality is formed, the de-extinction of animals (if we can even call it that), and so much more! Submit your own questions at imgettingcuriousish.com to hear your question answered by Greta on next week’s episode! Don’t miss out on this week’s Fast Fact that you can share with your friends near the end of the episode! Let’s further our curiosity together in this week’s episode of Curious-ish.
