Actually I'm gonna write another post. It's not a review of a video but just something I've been wondering about. Specifically, hard biological limits and extremophiles.
My favorite way to approach things, whenever I start wondering about anything at all, is to experiment with all possible edge cases. It really puts things into perspective sometimes and exposes certain characteristics/behaviors.
For example, what is the highest (and lowest) possible temperature a human can sustain? The highest core body temp would be around 43∘C (109.4∘F) before the proteins start breaking down.
Yet, extremophiles like Thermus Thermophilius are capable of surviving at much higher temperatures, so what gives?
Turns out mesophiles' proteins offer more flexibility, but that trades off for less heat stability, unlike thermophiles who are very rigid but super stable.
This article has a cool graph on how heat destroys proteins:
