Tackling football concussions head-on. I’m Bob Hirshon and this is Science Update.
Concussions have been plaguing football and materials scientist Ainissa Ramirez says that bighorn sheep could inspire solutions.
AINNISSA RAMIREZ (Author and former Yale materials scientist):
The horns are made out of a protein called keratin. Keratin is a very spongy, elastic kind of material and it absorbs some of the force.
She says it also spreads the impact out over time.
When a collision happens, the horns give a little bit and so that increases the time of impact, so the force that’s translated through the horns, through the head to the brain reduces.
If we decided to have football players with helmets with horns, there would be total buy-in, and if they said it’s also going to prevent concussions, then I think we’ve got a win-win.
I wouldn’t say to add the horns, but what we are saying is adopt some of the materials that would be in keratin into the helmet.
