Sumary of ‘Space pups’: Mouse sperm stored on space station produces healthy young:
- Japanese researchers found mouse sperm exposed to high levels of cosmic radiation for nearly six years produced a large brood of healthy, unremarkable “space pups.”.
- Their study was published Friday in Science Advances — which noted no signs so far of Mousezillas or rodent Hulks..
- Developmental biologist and lead author Teruhiko Wakayama told AFP on Thursday that there was little difference between mice fertilized by space sperm and sperm that had remained confined to our planet..
- In 2013, Wakayama and colleagues at the University of Yamanashi in Japan launched three boxes, each containing 48 ampoules of freeze-dried sperm, to the ISS for the long-term study..
- Freeze-dried sperm was selected for the experiment because it can be preserved at room temperature, rather than needing a freezer..
