Ancient DNA analysis reveals that sheep were domesticated over 11,000 years ago in the Fertile Crescent. By 8,000 years ago, early farmers were selectively breeding them. Sheep have been intertwined ...

The brain is the most well-protected organ in the human body, but it has a surprisingly high amount of microplastic pollution, according to a study published in Nature Medicine on Monday.
