A recent study found that the 105-year-old 'Adrian' helmet used by the French army in WWI can provide better protection from overhead blasts than a combat helmet widely used by the U.S. military.

"That was very surprising, actually," says Joost Op 't Eynde, the Belgian bio-engineering doctoral candidate at Duke who led the research project comparing three separate WWI-vintage helmets with the ACH model."It was only after the tests that we saw that the modern helmet was not better. And then we saw that, in certain scenarios, the French Adrian helmet had performed better.
"The protection of the warfighter afforded by helmets from threats ranging from bullets, shrapnel, blasts, vehicle collisions, and parachute landings has improved with improved helmet design and materials," the report's authors write."However, the level of protection from nonfatal brain tissue injuries, which may have health consequences beyond the acute phase, is not known.
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.
