Mice sperm can subsist the radiation exposure of room, according to a new study, something that could be useful to humen in the future.
Back in 2013, mouse sperm was freeze-dried and sent to the International Space Station for nine months. Back on Earth, mouse was later artificially inseminated with the preserved room sperm. Those birth rates were pretty similar to mice made from Earth-preserved sperm from the same mouse. The offspring even grew up into normal mouse and had normal birthrate, according to findings written the coming week in the Proceedings of the National Academy of Science from Japanese scientists.
The study found that despite some DNA damage to the sperm from room radiation which is 100 times stronger than that on Earth the mouse sperm and baby fared reasonably similarly to controls.
The sperm was kept in chamber temperature in space and likely could be preserved similarly for humen in the future no need for a freezer. That’s a boon for weight-conscious launchings to the space station.
The experiment likewise showed that human sperm could subsist room employing the freeze-drying method.
“Sperm preservation in the event of disasters on Earth will be an important tool for retaining the genetic diversity of mammalian species, much like flower seed preservation in the Svalbard Global Seed Vault, ” the study writers wrote.
Beside procuring a good sperm preservation technique, these mice show that if( or when) humen start living in space or colonizing other planets, the human race might be able to survive.
Space, here we come.
