The most effective form of vitamin B12 is methylcobalamin. The body uses methylcobalamin directly, so it’s very easily absorbed. The same goes for dibencozide, which the body uses for muscle development among other things. Canadians do not get dibencozide – they can only get it from the U.S. Cyanocobalamin is crap – don’t use it. Smokers should use methylcobalamin, as it will bond to the cyanide in the body and will be excreted though urine.
Locusta was one of the first recorded professional chemists. She was employed by several royal Romans, and even established a school for other chemists. Here’s why it was best not to piss off either her or her students.
Cyanide poisoning is not a nice way to go. Essentially it’s open-air suffocation. Cyanide ions in the body interact with an enzyme called cytochrome oxidase. This enzyme works with hemoglobin in the blood. It preferentially picks up cyanide when it should be picking up oxygen, meaning the body slowly dies for lack of “air.”
There’s a classic joke about how to get intoxicated at hospitals by claiming you drank methanol to get an IV with an ethanol solution. It’s not that methanol will kill you or make you blind… The problem is that the liver enzyme alcohol dehydrogenase turn methanol into formaldehyde (or methyl aldehyde). Ethanol binds to the same enzyme to inhibit the production of formaldehyde.
We all love seafood — but the ocean can be a terrifying place. The ocean depths are home to some deadly and poisonous creatures… so of course, people always try to eat them. Here are the scariest fish dishes you could possibly eat.
The article is incorrect – they’re not beheading the squid. They’re cutting its abdomen off. The brain of a squid is wrapped around its esophagus (between its eyes) – it’s very much is alive and very much with brain when they start to pour soy sauce on it.
The fact that a cephalopod brain is wrapped around its esophagus is what renders those fantasies of future cephalopod overlords so silly, because a bigger brain would mean they’d starve to death.
In 1982, seven people died in the Chicago area due to an unknown mal-intended person replacing Johnson & Johnson Tylenol tablets with cyanide tablets. This was an extremely big deal and it completely changed the world in a few different ways let’s look at how.
