The other two SEALs, including Lieutenant Metcalf, had a different type of damage in the same blast-affected areas. Star-shaped helper cells called astrocytes in their brains appeared to have been repeatedly injured and had grown into gargantuan, tangled masses that barely functioned. The lab plans to publish findings on the astrocyte injuries soon. Recent studies suggest that damage is caused when energy waves surging through the brain bounce off tissue boundaries like an echo, and for a few fractions of a millisecond, create a vacuum that causes nearby liquid in the brain to explode into bubbles of vapor. Those tiny explosions are violent enough to blow brain cells apart in a process known as cavitation.  @MarvClowder @deliverator @clive that's literally brain damages by #Sonar with cavitational bubbles and shit temporarily forming beyond the threshhold that makes one nauseous, incapacitates or kills a person... This seems rather expectable... The first two lines of the Wikipedia article on cavitation: Cavitation in fluid mechanics and engineering normally refers to the phenomenon in which the static pressure of a liquid reduces to below the liquid's vapour pressure, leading to the formation of small vapor-filled cavities in the liquid. When subjected to higher pressure, these cavities, called "bubbles" or "voids", collapse and can generate shock waves that may damage machinery. @MarvClowder @deliverator @clive and now.realize.that the strongest sonars can make water boil around them on full blast and that a lethal noise level is possible for literal miles... And whilst friendly submarines should.cease using sonar whilst divers are out, SEALs usually don't tend to be get deployed in friendly waters... ^  @rustoleumlove @MarvClowder @deliverator @clive basically samenreason you can see bubbles in an ultrasonic cleaner... Now imagine this happening within someone's brain... - There's a reason one doesn't put an,ultrasonic on a human head (even if there wasn't a skull making it pointless to try amd see shit)... |

Dr. Perl said privacy rules bar him from discussing specific cases, but members of the families who provided brains to study say the lab found interface astroglial scarring in six of the eight SEALs who died by suicide.
