To look at the evolution of modern bird feathers, we must start a long time ago, with the dinosaurs from whence they came. We see early incarnations of feathers on dinosaur fossils, and remnants of dinosaurs in a bird’s wish bone.
Carl Zimmer explores the stages of evolution and how even the reasons for feathers have evolved over millions of years.

How Does Toothpaste Make Orange Juice Taste Bad? [Bytesize Science]
In our latest episode, we take on a common breakfast disturbance - the foul taste of orange juice after you brush your teeth.
Toothpaste is loaded with a cornucopia of chemicals that add flavors, body, texture, and most importantly, the ability to clean your teeth. One compound in particular, a detergent known as sodium lauryl sulfate is responsible for the suds that you produce when brushing. As it turns out, this compound has an interesting effect on your mouth’s taste receptors.
Watch the video to find out exactly how SLS affects your sense of taste, and be prepared to amaze your friends at breakfast when you drop chemical facts on why this bitter combo leads to such a puckered up, gross experience.
