Why Don't Sheep Shrink In The Rain?
Adults Biology
Getting wet isn't REALLY what makes wool shrink; it merely exacerbates the friction between the wool fibers, which is stronger in one direction than another, so when agitated in the washer or dryer, they migrate in relation to each other in a process called "felting."

How does your immune system work? - Emma Bryce
Adults Biology
The immune system is a vast network of cells, tissues, and organs that coordinate your body's defenses against any threats to your health.

Emma Bryce takes you inside the body to find out.
What are mini brains? - Madeline Lancaster
Adults Biology
Shielded by our thick skulls and swaddled in layers of protective tissue, the human brain is extremely difficult to observe in action. 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.
