Rats Breathe Air From Lungs Grown In the Lab 112

Posted by timothy from the decellularization-is-cheating dept.
cremeglace writes "'For the first time, an animal has drawn a breath with lungs cultivated in the lab.' Although preliminary, the results might eventually lead to replacement lungs for patients. Researchers at Yale University have successfully applied a technique called decellularization that involves using detergent to remove all of the cells from an organ, leaving a scaffold consisting of the fibrous material between cells."

        Yeah; if you want to see impressive lungs, look at a bird.

        The impressive thing about a whale's lungs, is the percentage of air exchanged in one breath. The impressive thing about a bird's lungs is the percentage of oxygen they can take from the air.

You'll get much better results searching for that than trying combinations of "lungs fill with fluid."

      Honesty, as a dirty cigarette smoker, I would love the applications of this in the future. Seeing as smoking cigarettes is mostly consensual (granted your not encroaching on other peoples relative airspace, being tarnished with smoke on a crowded bus, or throwing your butts all over the damned place), I think this would be cool for the average person who enjoys cigarettes. The psychology of the previous statement (the enjoys portion) could obviously be argued, under the wing of the psychological / biological additions department.

      But if I am smoker that participates in my habit respectful of the wishes of other, courteous in my carcinogen ingestion, would it be such a travesty if there were an abundant supply (IE, people who haven't consensually and knowingly destroyed their lungs getting first priority, and the excess up for auction / sale), giving the smoker the ability to purchase new lungs. This understandably does not counteract the hundreds of other detriments to the body smoking yields, but at least of the the major concern of many.

      Of coarse any medical procedure that encourages a habit so vocally hated (yet balance book loved **tax revenue**), the average politician would have nothing of it the eyes of an irrational voter not seeing all sides of the argument for pay-per-lung adoption schemes, despite the process doling out fair opportunities to those in genuine need, I believe political rhetoric of fire-and-brimstone proportions would kill such a proposition before it even hit the table.

          In some countries smokers put in MORE money into the system than take out. The "limited dollars" often come from them in the first place. For example in the UK, smoking related problems cost the national health care system 5 billion UK pounds a year, but the tobacco tax revenue is about 10 billion a year.

          So just increase the tobacco tax in your country till it evens out or you get a net gain. Legit drug money...

          I'm a nonsmoker and I'm fine if smokers want to make extra contributions to society, and die younger in countries where "aging population" is a concern. As long as there are nonsmoking places and smoking places (don't ban smoking in restaurants/pubs etc, just tax establishments that allow smoking more- then you allow choice and don't miss out on revenue).

          People (especially children) should be educated on the dangers of smoking, but once they are adults smoking is not really a big problem to me. Second hand smoke might shorten my lifespan, big deal, bad drivers might shorten/ruin my life even more.
