wait if it's about eDNA? why were they swabbing salamander's cheeks?
it's environmental DNA.

Maybe you're trying to match individuals to dissemination, idk man neither of us were there
"How much DNA do salamanders absorb from the environment, and how much of that gets incorporated into their DNA?" I would assume.
WHAT?
eDNA is the idea of taking a environmental sample like water or air, and finding traces of DNA and figuring out what creatures live in the area. you wouldn't take a sample from an animal mouth to check for eDNA.
you could tell what salamanders live in a pond by getting eDNA from the water, but no real point in checking the DNA in the salamander mouth.
maybe to double check results for testing.
I'd be pretty impressed if salamanders readily incorporated environmental transposons into their genome. Don't octopuses rewrite their genetics on the fly though? I think I remember reading something about that years ago
This is what it's like being a psych nurse talking to an ICU nurse. It's the difference between
You put what WHERE???
and
The patient put what WHERE???
I love the exchange, but the backdrop of capitalism demanding results is grim.
I just want everyone to enjoy exploring and sharing without worrying about grants...
Eh, until we're truly a post scarcity society (if such a thing is even possible) scientist would have to justify use of resources no matter what the system we use.
Stop bringing your practical realism into my dreamworld moral absolutism
You use resources you have to justify them. Maybe to a voluntary committee. Maybe to a Soviet. Maybe to the supreme leaders appointee. Maybe to a sub unit of the technocratic cabal.
Since you're going to have to explain yourself anyway, may as well just do whatever you want and explain it to the court afterwards.
My wife and many of her friends are in medical fields, while myself and several of their spouses are in technical fields. We've had almost exactly the same exchanges.
Even in medicine, there are big blind spots between specialties. My radiologist who did my wife’s sonogram was like “yeah I got into this because I fucking hate needles. If I wanted to go into nursing I’d need to use them a lot. So here I am, doing all of the non-invasive stuff instead.”
Same with me and my wife except she's in civil design
I help elderly with their technology. A coworker does outreach for community events. We would both rather choke on a revolver than do the others job.
This is my dunderhead comparison. Look mom I'm like the science people in the meme
What the frog is eDNA?
How Edna writes her name when she forgets she has caps lock on.
Environmental DNA, apparently.
Ah, like when you monitor sewage for diseases.
Searching for it I mainly got Dame Edna Average and while she looks a bit like a salamander that didn't seem right.
I was immediately thinking about all the different prefixes for RNA and eDNA did not make any sense. Maybe "expressed DNA" but that's just the transcriptome and that also RNA again.
I only recently heard this for the first time too, when i watched this video about deep sea eDNA https://www.youtube.com/watch?v=8i95R3tgJIs
measuring cell stress (literally how much you can deform a cell) as a factor that can influence its development is a bit of a hot crossover field in Physics and Biology atm
I worked on that a bit! Never realized it had such a crossover potential. Also considering how physicists cant stand biologists and probably vice versa.
