Stanford bioengineer David Camarillo knows all too well that bicycling is the leading cause of sports- and activity-related concussion and brain injury in the United States. He's had two concussions as the result of bicycling accidents. While he doesn't doubt that wearing a helmet is better than no helmet at all, Camarillo thinks that traditional helmets don't protect riders as well as they could.
"Foam bike helmets can and have been proven to reduce the likelihood of skull fracture and other, more severe brain injury," said Camarillo, an assistant professor of bioengineering at Stanford.
