plastick (1607981) writes "In their experiments, researchers employed human embryonic stem cells, which possess the extraordinary ability to become any other cell. To simulate microgravity on Earth, the scientists used a NASA-designed machine which kept the cells nourished with oxygen and nutrients while constantly spinning to keep the cells in a state of freefall for 28 days.

After this experiment, the cells showed vast differences on the molecular level, with 64 percent of their proteins differing from those grown under normal gravity. Specifically, these microgravity-exposed cells generated more proteins that degrade bone and fewer proteins with antioxidant effects. Antioxidants protect against reactive oxidants that can damage DNA.

Microgravity also influenced levels of a broad range of other proteins. These include those involved in cell division, the immune system, the muscle and skeletal systems, calcium levels within cells, and cell motility.

These findings in embryonic stem cells may not bode well for attempts at procreation in microgravity."

  • Sex in space sounds great to me.

    Conception and subsequent embryonic growth in microgravity environments may be a bad idea.

    Accordingly, contraception for everybody. If you don't like it, don't leave the planet. (We won't miss you, anyway.)

We will have solar energy as soon as the utility companies solve one technical problem -- how to run a sunbeam through a meter.
