    These systems are coupled, so that whenever bone is broken down, newly formed layers take its place—neither should happen without the other, in a healthy adult. In space, however, there is an increase in osteoclast activity due to microgravity. This is a problem because osteoclasts break down the bones into minerals that are reabsorbed by the ...

    Eventually, White wrote about the effect in his book The Overview Effect — Space Exploration and Human Evolution (1987), [13] which has a fourth edition (2021). [11] White's work did not attain broad influence until the 2010s—a period of increased societal divisions and a new prospect of private space travel. [14]

  6. [citation needed] Little is known about the physical and psychological effect of long-duration microgravity and the high radiation that occurs in deep space. In addition, on Mars the crew members will be subjected to a gravity field that is only 38 percent of Earth gravity, and the effect of this situation on their physical and emotional well ...

    Phi; the symbol used for integrated information. Integrated information theory (IIT) proposes a mathematical model for the consciousness of a system. It comprises a framework ultimately intended to explain why some physical systems (such as human brains) are conscious, [1] and to be capable of providing a concrete inference about whether any physical system is conscious, to what degree, and ...
