If there is one good thing, it will make a lot of people. We are a productive children producer that 7 billion of us now roam the planet. But our reproductive ability can be printed quickly. Because of the many populations, only environmental damage or exploration, we also love to reach out to foreign planets.
And Mars needs mother and father. But because of the brutal radiation scattered on the ground and the difficulty of returning to gravity, it is easier to say than to finish.
Researchers know that space travelers can be harmful to human health by NASA’s Gemini mission in the 1960s. Scientists note that the capacity of bones in the astronaut’s foot before is less than 6% after less than two weeks in space. Contract muscles faster.
And since then, we have learned cosmic rays, anywhere in space and space stations, causing cancer and tissue disease and ultimately proving harmful to DNA and nervous systems.
Spaces are a place that can be regarded as humble, as well as for trained astronauts. Will there be a fragile environment with new embryos, fetuses and infants? How to disrupt our reproductive system at the outset? The answer remains unknown. Scientists do not know if women can even conceive, let alone get pregnant on board.
With the biology that is used against us, researchers are still trying to answer the important questions: how will we make the kid happy and healthy in space?
Sperm, meet the egg
Every aspect of creation of a child in space.No one has ever had sex on the spot, as we know it. Without gravity, the fact of easily holding your partner in hand to do anything can prove difficult.
And then the sperm and functional egg cells still need to be found to start over pregnancy, which requires a lot of mobile cellular action.
Over the past decade, scientists have been working on overcoming the mystery of reproduction in space. After a space race, the astronauts began to transport fish, nematodes, frogs and salamanders in orbit to test the reproductive ability out of the universe.
In a series of disastrous surprises, all of them have produced healthy children. But among successors, scientists attacked the walls. At the Russian satellite site in 1979, male and female male mice failed to cure on a mission of 18.5 days or chose to have no type – a demonstration of practice that can not be found in rats on Earth. The next experiment with rats contains other concerns.
Mouse to assist healthy children who come from frozen sperm who have been flying to the International Space Station for 288 days.
Not like a muddy and fertile friend, the rodenticates are mammals, anatomy, physiology and gene similar to animals.
Teresa Woodruff, vice president of research at the Department of Obstetrics and Gynecology at Northwestern University, states that mice are the same so that all the problems we will see in the first pregnancy should be as we will see in our situation. Other researchers agree.
Only mammals have placenta. So, to know the environmental effects of the environment, we have to use mammals, says Teruhiko Wakayama, director of Yamanashi University’s Advanced Biotechnology Center in Japan.
He has been in the last ten years studying mammals – usually rats – can return to the board. Without gravity Earth pushes all the down, needs to walk, walk and drag the objects back into orbit. As a result, even our bones and muscles are strong.
Because this force is very important for its pregnancy, and it is important for the growing fetus, Wakayama wondered if rats could also contain these conditions.
In 2009, Wakayama extracted eggs and sperm from mice, then dropped them to a device that highlights microgravity (technical terms for directing gravity astronauts). He watched the sperm wing in the eggs and after a few days of microgravity, he and his implant implant embryos in the standard gravity of mice.
The result is mixed
when many healthy and normal kittens are born, many embryos do not develop properly after implantation. As a result, mice have less progeny than mice in normal gravity.
To see if these results remain in space, where high radiation levels are microgravity, Wakayama contacted Japan Aerospace Explo
