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.

That's not quite the same thing - the 7 digit phone number has more to do with short-term memory capacity than visual perception. Miller's Law of short-term memory is we can store 7 +/- 2 items at a time, depending how complex they are.

Night and day difference for me, thanks for upgrading!

I'm a tall guy that fenced in college. You're a monster. But every fencer consents for this torture, so you can keep on keepin' on.

PhD in neuroscience here. I didn't specifically study musicology, but i did study the neuroscience of music.

The theory that holds the most water, in my opinion, is that music activates all the same parts of the brain as motor processing. It makes us want to move, and to make predictions about what's coming next. People like makimg predictions. It's also a pro-social activity that encourages bonding and communication. These are typically positive experiences.

Edit: you mentioned we like the breaking of patterns in music. Very true, we love syncopation. But we don't tap our foot to the rhythm, we groove to the beat.

I'm jealous. I have a hard time getting it to the table, but when it's there I'm living my best life.

I studied parts of the basal ganglia, part of the dopaminergic circuits of motor control. I'm not sure if it's a poorly written (news) article or the scientist was overstating his position - I don't know any neuroscientists who think dopamine is "sprayed" across the brain.

Edit: The paper is a breakthrough because it's reporting the first-ever direct imaging of dopamine signaling. But the news article mischaracterizes it.

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?
