It's old news. There is even “And Dream of Sheep” — Grey’s Anatomy, Season 15 Episode 17.
That’s the episode where they mention using tilapia fish skin to treat burns.
Original U.S. air date: March 14, 2019.
Doesn't make it any less interesting. And in spite of it not being new, it doesn't look like it's out of the experimental stage: the article mentions it's difficult to get the tilapia skin processed and sterilized.
The article is 9 years old so that may no longer be the case
Old news comes off dismissive. Doesn’t have to be a brand new discovery to be noteworthy.
2019? I'm surprised they kept it running for that long.
