    Scientists no longer have to worry about their rat sperm bottle rupturing during transportation
    .


    Japanese researchers have invented a method to freeze dried sperm on a plastic film of weighing paper so that the sample can withstand the test of sending it by postcard


    "When I developed a method of preserving mouse sperm, that is, freeze-drying it on a piece of paper, I thought it should be able to be mailed by postcard, so when the rat babies were actually born after mailing, I was very impressed.
    "The first author Daiyu Ito of Yamanashi University in Japan said, "Compared with any other method, the postcard method is simpler and cheaper
    .


    We believe that sperm never thought that one day it would be put in the mailbox


    Ito is a member of Teruhiko Wakayama's laboratory, which was the first team to successfully freeze-dry and preserve mammalian sperm.
    They sent the sperm to the space station to study the effects of space radiation on young mice
    .


    Sperm is initially stored in a glass ampoule, or glass bottle; although these bottles are small, they are bulky and easily broken, making the sperm they carry unusable


    Therefore, considering these obstacles, the laboratory began to look for a new preservation method-neither damaged nor too much storage space
    .


    Plastic films are most suitable because they are compact and will not break


    Through this new preservation method, the sperm of thousands of mouse strains can be stored in a book, which scientists call the "sperm book
    .


    " The book was stored in a refrigerator at -30°C until further use in experiments


    Ito, Wakayama and their team wanted to figure out whether the sperm could still be effective even after being mailed dozens of miles.
    To their delight, it did indeed work
    .


    Scientists were able to post mouse sperm in the "sperm book" via postcards by pasting a plastic film on the postcards without any protective measures


    Scientists believe that once the "sperm book" and mailing methods are perfected, they will have a huge impact on their research fields worldwide
    .


    Their next goal is to be able to store at room temperature for at least one month


    "It is now recognized that genetic resources are the wealth of mankind in the future
    .


    Although many genetic characteristics are not necessary for survival, it is necessary to preserve them according to the environmental background
