Sorry sextonauts, making the first baby in space baby is going to prove difficult because embryonic stem cells don't act the same way in zero gravity. So is it cyborg humans or banging aliens?
Scientist have shown how full-grown adults suffer the longer they stay in microgravity - living in zero-G causes muscles and bones to weaken, and makes the heart beat irregularly. And now, Australian researchers have found microgravity tampers with stem cells. In tests, 64% percent of stem cell proteins were fundamentally different from how they would be in normal gravity. And the changes weren't good. Most of the altered proteins would weaken bones and allow increased oxidative damage to DNA. Damage was also done to proteins involved with the immune system, proper cell division, calcium levels, and much more.
Clearly, gravity is somehow responsible for a vital part of the body's mechanical or circulatory feedback, helping to keep bones and blood vessels healthy. My layman idea? Artificial gravity! Problem solved? Perhaps, and then you can save all the zero-G sex for kinkier times...
