We had... a lot of space news yesterday. Some of which we'll get to. But I'll jump to what I see today which is longterm health in space. We've poasted a few poasts on microgravity mitigation.
The focus today is on kidney damage. Not just stones; damage. It seems that weightlessness causes the kidneys to lose the ability to process calcium.
I vaguely recall that stones can form due to germs damaging the kidney and, well... space does a number on the immune system as well. Something called "quercetin" can help with germs, for short shuttle hops (like the Starliner).
Overall if we get hibernation, which I agree we'll need to reduce food-/oxygen-/water-demand for a long voyage; hibernation too will need to be within spingrav.
