Ketchup? Somehow I don't think we'll see it in football helmets.

The non-Newtonian fluid you are most familiar with is ketchup.  Flows slowly then more quickly once you whack the bottle and it jumps from your hamburger to your significant other.

Agreed, Gorksi. The more we learn about brain injuries, the more I believe my Thanksgiving football-watching marathons are apt to change.

These result seems familiar.  The brain mechanically is weakest preventing collision with the skull in rotation towards the temples. The brain stem has poor torsional rigidity.

The research into footbal injuries is useful in determining the cause. But I don't think this will help eliminate the problem. High impact from a tackle not only damages the brain it also damages the rest of the body as well. Some football players have trouble walking, getting out of bed, etc. A helmet would not help them. I'm afraid the only solution, sometime in the future, will be to limit contact. Football will never be the same.

Admittedly, the term "non-Netwonian" was only vaguely familiar to me, naperlou. I had to ask for an explanation. I agree, though, it's a cool application.

Chuck, this is a really cool application of technology.  The use of more detailed sensors is an important step.  The solution using non-Newtonian materials is really interesting.  The name, though, is kind of strange.  I understand it, but using non in a name always seems strange to me.  It is like NoSQL in the Big Data field.
