Conch Shells Inspire Next Generation Helmets, Body Armor (rdmag.com)
New submitter omaha393 writes: Researchers at MIT used a 3D printing approach to develop a biomimetic composite capable of withstanding 70-85% more resistance than typical helmet designs. The material was manufactured using a composite of hard and soft printable polymers called VeroMagenta and TangoBlackPlus. The polymers were printed to overlay in a specific pattern that mimics conch shell molecular hierarchy, thus preventing cracks from spreading and offering a substantially more crack-resistant material. The researchers propose the material can be custom tailored and readily printed for future helmets and body armor manufacturing. The study has been published in Advanced Materials.

"AGGGHHH TOO MANY OHMS!! LITERALLY 1 MILLION OHMS! I'M NOT... going.. to... hey, wow this is a nice helmet! I really couldn't have withstood that resistance for much longer. Thanks ConchHat, you saved me!"
Nothing posted to
A scientific paper was published but you need to pay to read it. Some guy reads it or maybe skims it and to meet a quota, he writes a quick summary of the paper but doesn't include any illustrations of a conch shell. Omaha393 sees this summary and submits a quick summary of that summary to Slashdot where BeauHD writes a quick introduction and posts it on the main page of Slashdot. Nobody will read that summary of a summary yet they will discuss and debate the pros and cons of a broad generalization of the topic and some may even post racial slurs because they thinks it's clever. Penis.
I wonder if this would help football players. Something to keep concussions from happening with such frequency.
This specific development? Probably not. It sounds as though this material is about as hard as current football helmets, and perhaps harder. Impact causes concussions because sudden acceleration or deceleration of the head causes the brain to hit the inside of the skull. But perhaps the knowledge and techniques gained here might allow them create padding for football helmets that absorbs impacts better than the current materials.
'The Economy' is a giant Ponzi scheme whose most pitiable suckers are the youngest among us and the yet-unborn.
No, that can be fixed by putting leather helmets back in the game. Bet those defensive players won't be putting their heads down then!

Bullshit. Go do some simple fact checking. It's illegal for felons, as are guns, but I can buy and wear body armor if I so desire.
...to get a conch on the head?
I've calculated my velocity with such exquisite precision that I have no idea where I am.

My information was dated, you are correct. So many things to keep track of over the course of 6 decades, heh! Great news, IMHO! Hopefully many lives will be saved as a result. There were decisions on relevant court cases and precedents set so that there is no restrictions on civilian body armor (except in a crime, sane as a hammer, really). I will note however that many US suppliers/distributors/sellers will still refuse to sell without LEO-LEA/Gov credentials, despite it not being illegal to sell to the general law-abiding public. Curiously, some places which refuse non-credentialed in-person sales will sell online without any credentials required. Israel has a strong export market to the US for top quality BA as a result.
With all the terrible decisions coming out of the courts over the last few decades, seemingly on 'turbo' the last couple decades, it's a pleasant surprise when they actually get it right!

Progressivism (aka US 'Liberalism'): Ideas so good they need a police/surveillance-state to enforce.
Too bad that by law, this can't legally protect a civilian life from a gunshot.
Whose law . . . ? In which country . . . ? Do you, by any chance, live in a fascist dictatorship . . . ? Or a police/surveillance-state . . . ?
Around my parts, wearing body armor in public spaces is required by law for safety reasons. Kinda sorta like wearing seat belts is required in some places.
Body armor is illegal for non-LEO/military personnel . . .
. . . which is not a problem for us, as we are all LEO/military personnel. Folks in other parts get baptized at birth; we get deputized at birth. Firearm ownership is mandatory for home protection. Each household needs at least a PDW, like a Tavor, an H&K MP7A1 or a Beretta Mx4 and additionally a sawed-off tactical shotgun with phosphorous Dragon's Breath loads: "Feel THAT burn, Senator Sanders!"
Some animals are more equal than others.
That is a corollary to Kurt Gödel's Incompleteness Theorem, but his biographers have no definitive information on what firearms he carried. Phone calls to the Institute for Advanced Studies near Princeton University inquiring about the body armor worn by faculty members were answered with:
"Eh?"
