It's less about managed culls and more about raising funds for conservation.

Hot take, I'll offer an alternative perspective. Obviously, poaching is one of the most disgusting crimes. Sourcing animal parts for folk remedies is reprehensible.

Responsibly managed hunting generates a ton of money, some of which which gets invested into the local community and into conservation efforts.

The key word here is responsible. If a land manager shared wealth in an equitable fashion with the locals, and demonstrates careful management of animal herds by close monitoring of populations, that's responsibility. I wouldn't want to hunt on lands owned by, say, a literal nazi in South Africa. But, unfortunately, as long as we live under capitalism, I have a hard time imagining a different way to encourage the world to preserve our natural resources.

Ducking autocorrect strikes again. Astrocytes

That's a surprising statement to me. Honestly, those aren't even the most important. Glutamate is the most common neurotransmitter in the brain. But dopamine, norepinephrine, and serotonin are responsible for some very "classic" bodily functions like reward, adrenaline, and sleep.

Now, hormones are typically separate from the brain - there's a barrier between neurons and your circulating blood maintained by astrocytes. This is the so-called blood-brain barrier. I do not know if there are examples of Oxytocin and Epinephrine crossing the BBB, as I did not study it. https://en.wikipedia.org/wiki/Blood%E2%80%93brain_barrier?wprov=sfla1

Sorry, that was maybe too pithy for a science post. https://www.smbc-comics.com/?id=3339

Dopamine does a lot in the brain. Much of its function depends on where it's active. When released in the ventral tegmental area, it causes reward and happiness. In the basal ganglia, dopamine helps us coordinate movement.

Since I'm already on my soapbox, I'd like to point out there's more than 3 neurotransmitters. These are the basic ones:

  • Dopamine - reward and muscle movement
  • Acetylcholine - motor neurotransmitter
  • Glutamate - primary excitation transmitter, important for memory and overall function
  • GABA - primary inhibitor transmitter
  • Glycine - inhibitor in the spinal cord
  • Serotonin - the other happy hormone, involved in a lot of complex stuff like sleep, depression, and hunger
  • Norepinephrine - fight or flight, adrenaline
  • Epinephrine - the other fight or flight hormone
  • Oxytocin - the nipple clamp hormone

This one tilts me the hardest. It's like saying a 3-ligjt stoplight only uses 33% of it's lights.

Actually, no, the bio soster shares the same biological father. This was an embryo adoption, not IVF

Personally, I disagree. The baby's bio sister is, literally, a biological sister whose DNA comes from the same parents.

The limiting factor in utero is the health of the placenta. Past a certain point, the organ no longer functions and the baby does not survive. This is why (at least in the US) inductions are required past a certain point.

Because, I shit you not, it's cheaper than adoption in the US.

I forget the name of the app, but we used a potty tracker. Basically, once we realized our puppy went to the bathroom X hours after eating or drinking, we took him outside a few minutes before then.

I've also heard you can take those pee pads and gradually move them closer to the door until they're outside.

Mingus is one of my favorites.

 

I got into an interesting discussion at work about an MRI sequence I've never used before. For context, I did a bunch of brain imaging in grad school, and now at work I'm encountering things that aren't the brain. Shocking.

The technique in question is trying to look at the amount of cartilage in a joint. I assumed the best way to identify potential problems with the MRI is to use a phantom like this one: https://www.truephantom.com/product/adult-knee/. We did this in grad school, but our phantom was basically an expensive jug of fancy water, which, apparently, looks enough like a brain to calibrate the machine.

It turns out the hospital just takes a random resident, puts them in the MRI, and takes MRIs of their joints. I'm assuming it's because the hospital doesn't want to pay $10k for a fancy fake knee.

So now I'm curious, if the radiologists and radiology-adjacent folks are out there, how many different phantoms do your teams own?
