Mice sperm can survive the radiation exposure of distance, as per a new study, something which could be helpful to humans in the future.
Back in 2013, mouse sperm was freeze-dried and delivered to the International Space Station for 2 months. Back on Earth, mice were then artificially inseminated using the preserved distance semen. Those arrival rates were pretty similar to mice generated from Earth-preserved sperm from the same mice. The offspring grew up into normal mice also had normal fertility, based on findings released this week in the Proceedings from the National Academy of Sciences from Japanese scientists.
The analysis found that despite some DNA damage to the semen from area radiation which is 100 times stronger than that on Earth the mice hens and sperm fared pretty similarly to controls.
The sperm has been kept in room temperature in distance and likely could be kept similarly for people in the long term no need for a freezer. That is a boon for weight-conscious sticks into the space station.
The experiment also revealed that the human sperm can survive space using the freeze-drying technique.
“Sperm preservation in the event of disasters on Earth will be an important tool for maintaining the genetic diversity of species, so similar to plant seed preservation in the Svalbard Global Seed Vault,” the study authors wrote.
Beside locating a great sperm preservation method, these mice show that when (or if) humans start living in distance or colonizing other planets, the human race may have the ability to survive.
Space, here we are.
