The core mechanism — damage signals and repair cycles

1:05:06don't do mitosis. They don't cell divide. So once you have them, you have them. So maintaining the cell state of a neuron is way more important than, let's say, skin cells. Skin cells, if you've got something that's bad, you shed it, you make new ones because those things are going through mitosis all the time. Muscle cells as well, they're replicating all the time. Neurons, on the other hand, you got what you got. And so you need to maintain it, right? which is why animals with neurons might require sleep because DNA damage in a neuron is way more important to fix than anything [clears throat] else. >> And so in order to protect your limited neurons, make sure you share the pod with a friend because what better way to stretch out and exercise those neurons

1:05:48than listening to the from first principles podcast. It's for your brain health. >> Yes. So if they ask you this podcast helps my mental health, my biological mental health >> by stretching and pulling and keeping flexy >> and then get some sleep right after because then that'll actually studies have shown that you know sleep actually consolidates that memory into long-term storage. So you might actually remember something that we're talking about. >> It's it's for your health. That's why you listen to the pod. Great story number two. We started with string theory. >> Yeah. Then we went into this sort of biology, neuroscience, sleep story, understanding a little bit more about sleep having a larger scope of value

1:06:32>> to to other sort of animals within the animal kingdom. >> And we're going to end this episode with a space story. >> Yes. >> Uh story number three is about dark matter. Yes. >> Dark Matters First Frontier and the Discovery of Cloud9. Not that Cloud9, a different Cloud N. Or is it? >> Or is it? I don't know. I don't know how it was named, honestly. We will get to that question, but astronomers may have found the first example of a primordial gas cloud trapped in a dark matter halo offering a rare glimpse into how the

1:07:13universe's first structures formed billions of years ago. This is coming in the Astrophysical Journal letters on January 7th from the Space Telescope Science Institute, the Universita Daglas Dudi de Milano Bioca, University of Victoria and another placement I think they might be third place in our stories of the University of Wisconsin. >> Wisconsin is doing well in our stories. >> They this they are performing very very highly. Um, so what makes Cloud9, the
