AI Thread Summary
The discussion centers on the potential necessity for Earth-like gravity for human survival, suggesting that living on other planets may be unfeasible. It highlights the possibility of using rotating space stations to create artificial gravity through centripetal acceleration, which could mitigate some effects of low gravity. The conversation also touches on the use of low doses of anabolic steroids to prevent muscle wastage in low-gravity environments, emphasizing minimal side effects. Concerns about long-term colonization of other planets are raised, noting that harsh conditions and the need for biological engineering present significant challenges. Additionally, there are inquiries about the effects of different gravitational environments on embryonic development, referencing past experiments with tadpoles in zero gravity. Overall, the dialogue reflects a cautious outlook on human adaptation to extraterrestrial living conditions.

Our bodies may require a gravity that is equal to that of Earth. If so, then it may never be possible to live on other planets. The future of humanity may therefore be in outer space, for example in rotating space stations.

Does anyone know more about this?

Surely the rotating space stations could rotate at the necessary angular velocity to provide us with sufficient centripetal acceleration?

They could use low doses of anabolic (low androgenic) steroids to prevent muscle wastage. Side effects would be minimal (because of the low doses and the specific nature of the steroids that would be used for this purpose).

I think this largely assumes that the person is returning to Earth someday (in which case bone & muscle loss would be difficult once he/she returns to "normal" gravity). If the person is planning permanent colonization (obviously a goal for future generations), then the problem may not be as great.
 
Other planets are extremely harsh. We could go there at enormous cost, but humans are not made for other planets. Colonization will await serious biological engineering.
 
I also wonder about the effects of different gravity in the embryonic development... I think they grew tadpoles (or a earlier stage, I don't recall) in zero gravity once, and they grew somehow turned in a wrong direction, but I don't remember of other effects, if they completed the development besides that or not...
 

Thread 'Body dysmorphic disorder (BDD)'

https://www.nhs.uk/mental-health/conditions/body-dysmorphia/ Most people have some mild apprehension about their body, such as one thinks their nose is too big, hair too straight or curvy. At the extreme, cases such as this, are difficult to completely understand. https://www.msn.com/en-ca/health/other/why-would-someone-want-to-amputate-healthy-limbs/ar-AA1MrQK7?ocid=msedgntp&cvid=68ce4014b1fe4953b0b4bd22ef471ab9&ei=78 they feel like they're an amputee in the body of a regular person "For...

Thread 'Did they discover another descendant of homo erectus?'

The study provides critical new insights into the African Humid Period, a time between 14,500 and 5,000 years ago when the Sahara desert was a green savanna, rich in water bodies that facilitated human habitation and the spread of pastoralism. Later aridification turned this region into the world's largest desert. Due to the extreme aridity of the region today, DNA preservation is poor, making this pioneering ancient DNA study all the more significant. Genomic analyses reveal that the...

Thread 'Warning of new opiod drug (nitazene) on the streets: Question re strength...'

Whenever these opiods are mentioned they usually mention that e.g. fentanyl is "50 times stronger than heroin" and "100 times stronger than morphine". Now it's nitazene which the public is told is everything from "much stronger than heroin" and "200 times stronger than fentany"! Do these numbers make sense at all? How do they arrive at them? Kill thousands of mice? En passant: nitazene have already been found in both Oxycontin pills and in street "heroin" here, so Naloxone is more...
