Researchers have developed a new, lightweight foam made from carbon nanotubes that, when used as a helmet liner, absorbed the kinetic energy caused by an impact almost 30 times better than liners currently used in US military helmets. The foam could prevent or significantly reduce the likelihood of…
If you actually read the article, it explains that a combination of linear and rotational energy result in a shear-type movement of the brain that could cause significantly more severe brain injury compared to a linear movement. This tech would reduce the rotational energy experienced by the brain if successful.
People not reading the article seems to be an even worse problem than on Reddit. At least there if you kept scrolling you’d find someone who read the article while here oftentimes all of the top level comments haven’t and are up voted by those who also haven’t read it.
