“Is Laminin All That Louie Giglio Says It Is?”

There are some crazy-popular YouTube videos featuring Louie Giglio about a cross-shaped molecule called Laminin that holds us together. What’s your take on it?

As a biologist myself I was intrigued when I heard about it and watched one of his YouTube videos. He really had to pump the crowd to get the reaction he wanted when he put it on screen. He almost always uses the crafted diagram, not an actual photograph, because the diagram shows the cross far better. Seemed a little forced to me.

Some observations:

1. The cross is not Jesus, so we are not held together by a symbol of Jesus. The cross is just the symbol of crucifixion, maybe.
2. Any adhesion molecule is going to need a way to interlock with another and this shape works well.
3. As mentioned above, when you see an electron micrograph (tiny tiny photo) the cross shape is not so clear. Textbooks will naturally lay it out differently.
4. Sorry, no goose bumps for me.
