Humans are truly specialists of all terrains. - A team of four Italian Gruppo Operativo Incurson (Operational Raider Group) combat swimmers emerging from a Salvatore Todaro (S526)-class diesel attack submarine. #military #capable #tactical #ocean #deepblue #frogman #swim #human #deadly
Galena is the principle ore of lead, and forms glistening silver cubes with almost unnaturally perfect shapes. Although lead is normally extremely flexible, the sulphur content of galena makes it extraordinarily brittle and reactive to chemical treatment.
Galena is capable of taking an equally heavy toll on workers and amateur researchers who are exposed to it.
Contact with specimens may lead to lead dust exposure, while workers in mines face a high risk of poisoning from contact with the mineral and the deadly dusts released through production.
Once extracted, the lead content from this mineral poses environmental and health threats during treatment and extraction.
Galena has a cubic fracture, and if hit with a hammer, the crystal will shatter into multiple smaller replicas of its original shape.
I don’t know why but the Httyd Dragons are incredibly hard to make (at least with beads).
What are your favourite dragons ever? Not just from Httyd - I mean OF ALL TIME :D Mine are Toothless, Smaug and Shinerai <3 And maybe the Ukrainian Ironbelly from Harry Potter. The Gringotts dragon. This one was lovely too.
“For everybody, it was a disease of south-eastern Asia and Australia,” Eric Bertherat from the World Health Organisationtold Angus Chen at NPR. “But we are discovering that this disease is present in many other regions worldwide.” In some areas, the death rate can also be very high, “up to 70 percent” says Bertherat. This is especially common if not treated correctly. “It’s a big burden, equivalent to rabies, and that’s a severe disease.”
The bacteria that causes it, Burkholderia pseudomallei, lives in soil and can either be inhaled or enter the body through cuts and breaks in the skin. It causes septicaemia, which is an overactive immune response triggered by an infection. This causes a whole body inflammation, which can lead to death if not treated.
is not a manmade product like many think. It is one of most terrifying minerals on the planet. Where other minerals act as toxins through their chemistry and sicken victims of accidental poisoning.
Asbestos conducts full scale mechanical sabotage on the human lung. Asbestos is a fully natural category of minerals composed of silica the most abundant of Earth’s hard elements, iron, sodium and oxygen.
Asbestos deposits consist of aggregates of thousands of tiny, fibrous crystals that can become airborne and lodged in the human lung, these can be seen in image 3.
Carcinogenic effects occur through persistent irritation of the lung tissues, leading to scarring.
Asbestos formations can also be uncovered among any set of silica rocks, warranting caution when exploring. Strangely, natural weathering leads to natural distribution of asbestos in Earth’s atmosphere, as a result, many humans carry some asbestos fibres in their lungs.
