DailyDirt: What Kind Of Blood Do You Have?

from the urls-we-dig-up dept

Artificial human blood could make medicine a whole lot easier -- with no more blood drives or inefficient blood matching and possible harmful immune responses to blood transfusions. But until we perfect a way to grow human blood instead of siphoning it out of other people's veins, we're stuck with a somewhat tricky supply chain of a vital fluid. Researchers and vampires are very interested in the field of blood, and if you're not too queasy, check out these links. After you've finished checking out those links, take a look at our Daily Deals for cool gadgets and other awesome stuff.

    Haemoglobin And Chlorophyll ...

    ... both contain the same structure of four pyrrole rings in a ring (yes, a ring of rings) with a metal atom in the middle. In blood (the “haem” part of the molecule) this metal is iron; in plants, it is magnesium.

    The difference in colour (red versus green) comes down to that metal atom.

    "their blood is an extraordinarily 'universal' blood type that can be donated to a wide population of people because it doesn't trigger an immune response." This is completely false--get a new science fact checker. They don't trigger an immune response to the Rh protein, but any other protein in blood is fair game.

    Ants

    Citation needed but as far as I know, ants actually have clear blood.

    Re: Haemoglobin And Chlorophyll ...

    I inherited a rare condition in which instead of a ring of pyrrole rings, my hemoglobin* is structurally an instance of Antoine's Necklace. Makes it difficult for doctors to take a sample in finite time, but the up side is that I can't bleed to death.

    * - I'm in the US, so US spelling. Using 'extra' vowels lands us on the Do Not Fly list.
