Reply to comment by DreamerOfRain in Is it true the humans could breathe and live in the atmosphere of Venus? by Impossible_Mine_1616

I guess the hard part is that you can't use any materials there to construct anything. Nothing in the foreseeable future would be able to survive a trip to the surface and back. So everything would have to be extraterrestrial. With Mars or a moon colony, the thought is that you could mine raw materials from the surface and use them to construct things. Venus doesn't even have a moon you could mine.

Reply to comment by Stephanie87-123 in Recently a gene therapy for a rare inherited neurodegenerative disorder was approved. How come cure is achieved through bone marrow transplantation? by nickoskal024

So if I understand, in the case of genetic metabolic disorders, introducing the missing metabolic function to modified blood cells helps support non modified cells. Do the toxic compounds move from the native cells to the modified cells where they are properly processed?

Do you know where we are in terms of safety for gene therapy?

Reply to How does the reaction of Fe3O4(s) + H2(g) function? by Sturmwolken

From the equation you've posted you're reacting magnetite with hydrogen gas directly, and generating water vapor and iron as your end products. It's been ages since I calculated enthalpy, but quick searches say you'll need to put in 150kJ of energy per mole reacted.

Said differently, in boring conditions, wet iron rusts, sometimes into magnetite and if it does so, it will evolve off hydrogen gas.
