Study Finds Century-old Combat Helmet Superior Shield Against Brain Trauma

That's because ever since the first modern combat helmet came out in 1915, these so-called"brain buckets" have been designed to protect heads not from invisible shock waves, but from shrapnel, bullets and other blunt physical objects.done by a team of Duke University researchers finds that the 105-year-old"Adrian" helmet used by the French army in World War I can provide better blast protection than the Advanced Combat Helmet widely used by the U.S. military.
"The geometry of the helmet can make a big difference," says Op 't Eynde."I'm not sure a crest or something like it would work with a modern design, but just being aware of how the geometry might affect the way that the head and the brain might experience a shock wave is definitely something that I think should be kept in mind in helmet design."
Others, though, insist that a lack of a complete understanding of how blast waves affect the brain should not be an obstacle to coming up with helmets that do a better job of shielding soldiers' brains. "We've spent billions of dollars — I did, as vice chief of staff — researching traumatic brain injury and post traumatic stress, and we really haven't gotten much return on that investment," says Chiarelli.

New Study Finds Reading Comprehension Down Amongst Dumb Fucks Perusing This HeadlineYOUR LOCATION—Discovering a complete failure to understand simple English prose that was nothing short of unbelievable, a new study published Friday found reading comprehension is down significantly amongst the dumb fucks reading this right now. “Our data found that exactly zero of the knuckle-dragging dimwits currently reading this article are capable of processing words and deriving meaning from them,” said the study’s lead researcher, Caroline Yates, who described an alarming, across-the-board decline in the ability to comprehend nuance and discern subtext among the drooling rabble of perplexed simpletons casting their empty, glazed-over eyes on this page. “In fact, we found that you probably just had to reread that last sentence because you fucking morons didn’t know that ‘perplexed’ is a synonym for ‘confused.’ So let us spell this out for you: You no read good. You bad at word knowing.” Yates added that the inability of our shit-for-brains readers to mentally grasp these very words would not stop the numbskulls from smashing their keyboards like fucking Neanderthals to post the most asinine, meaningless babble possible in the comments.
