Researchers Discover A Surprising New Role for Lungs: Making Blood (ucsf.edu)

schwit1 quotes ScienceAlert: In experiments involving mice, the team found that lungs produce more than 10 million platelets (tiny blood cells) per hour, equating to the majority of platelets in the animals' circulation. This goes against the decades-long assumption that bone marrow produces all of our blood components. Researchers from the University of California, San Francisco also discovered a previously unknown pool of blood stem cells that makes this happen inside the lung tissue -- cells that were incorrectly assumed to mainly reside in bone marrow. "This finding definitely suggests a more sophisticated view of the lungs -- that they're not just for respiration, but also a key partner in formation of crucial aspects of the blood," says one of the researchers, Mark R. Looney.
The platelet-producing cells actually migrate from the bone marrow to the lungs.

And this is only now being discovered. Another reminder of how little we know.

Lungs do all the work. Bone marrow gets the credit. Sounds like most bosses. Nothing new or surprising in that.

Burning organic matter of any kind, no matter the source, causes lung cancer, even if it is inhaling from burning fucking oranges and ordinary grass.
This is a general rule proven by chemistry, science, and medicine, and weed being organic is part of it. So no, there is no exception or excuse.

What?!? We DON'T know everything??

I'm sorry, this is wrong. The science has already been settled. You are INCORRECT, go back to the drawing board and do it until you get it right.

THAT's what irks me about that line. If we know everything, if it's all actually settled and done with (except for a few minor lose ends), then we need no more scientists or research -- DO WE? SETTLED science then just becomes dogma, no better than religion.

If "The Ancients" knew everything -- or if the current set of scientists know everything -- then we're done, all we need are yet more marketeers to sell us things in different combinations. That being said, you move forward with what you believe you know but you don't set it in stone, never to be examined again.

Good for these guys.
