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.

I wonder if this is where HIV hides when people who are HIV+ are on meds and the virus is undetectable. I don't really know anything, but it was my first thought.
FWIW, researcher have already discovered that HIV hides in the lymph nodes... But nice try.

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.

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.
If the universe is someone's simulation -- does that mean the stars are just stuck pixels?
GP is just wild speculation, but is there a compelling reason to believe that HIV couldn't hide in multiple places?
This is my signature. There are many like it, but this one is mine.
If you ate it maybe... the parent's point is that smoke is bad for you, same for fine dust. Source doesn't matter as much.
I take it from your post you're not a scientist? I will assume you're an engineer for designing an analogy. If I have a meter stick, that it is a meter can be 'settled' even if our degree of certainty as to how precisely it is a meter is in question. If it is to be used for framing a house, we probably don't even need to check. If we're going to use it to build a machine, then we have to see about measuring its degree of precision. This research showed that while we were correct about how platelets are generated, the progenitor cells can migrate to the lungs. While we have a more precise view than we did before, the previous view is still essentially correct on the important points. Similarly, it can be settled that we have a common ancestor with dogs, even if the precision of our dating for the common ancestor is under frequent revision. This is how science can still be both settled and subject to change.
leukemia is a cancer of the white blood cells. The cells being made in the lungs are platlets, not white blood cells. Not saying the lungs cant make white blood cells, but for now it looks like the major contributor to most blood components is marrow, so that is likely why current marrow targeting treatments work.
