Submission Statement:

This is a news article that elaborates how a team of scientists succeeded in growing up "mini guts" of humans inside mice. This is a useful advancement for humanity because it means we may be able to test some drugs or medicines on these mice without having to apply it on humans.

Which by turn, could help in developing some drugs for all of humanity. Or at least, test the side effects of already-existing drugs.

The Biotech applied is an impressive work, I invite you to read the article to see how it was done.
