Getting Under Our Skin

Explore how our bodies change and age over time, and the three common markers scientists use to measure aging. -- If you want to learn a tree’s age, you can count their rings. When it comes to humans, scientists have yet to find any visible traits that mark our age with the same specificity. But in the past few decades, they’ve discovered small, invisible markers hidden within the body that do change over time. Juulia Jylhävä shares what these markers can tell us about our health, history, and future. Lesson by Juulia Jylhävä, directed by Flaka Kokolli, Diellza Franca, Flammorum Animation Studio.

Luckily, scientists can use brain organoids — pencil eraser-sized masses of cells that function like human brains but aren’t part of an organism — to look closer. How do they do it? And is it ethical? Madeline Lancaster shares how to make a brain in a lab. Lesson by Madeline Lancaster, animation by Adam Wells. Thank you so much to our patrons for your support!

But can anyone learn to smell with the sensitivity of those experts? Alexandra Horowitz shares three simple steps to a better nose. Lesson by Alexandra Horowitz, animation by Black Powder Design.
