Explanation: You are a spaceship soaring through the universe. So is your dog. We all carry with us trillions of microorganisms as we go through life. These multitudes of bacteria, fungi, and archaea have different DNA than you. Collectively called your microbiome, your shipmates outnumber your own cells. Your crew members form communities, help digest food, engage in battles against intruders, and sometimes commute on a liquid superhighway from one end of your body to the other. Much of what your microbiome does, however, remains unknown. You are the captain, but being nice to your crew may allow you to explore more of your local cosmos.

说明: 你是一艘航行在宇宙中的太空船,你的狗狗也是。在我们生命的历程中,我们全都携带着数以兆计的微生物。这些巨量的细菌、真菌和古生菌 ,它们的去氧核糖核酸 (DNA)和我们的不同。这些在你体内,总称为微生物组的船伴,在数量上胜过你的细胞。你的船员组成一个个不同的社区,它们协助你消化食物,参与反抗入侵者的战斗,有时甚至经由液体超级通道,从你的身体的一端通行到另一端。然而,你的微生物组大部分的功能目前仍然不明。你虽然是船长,但善待你的船员,或许能让你有更多时日探索你所在的宇宙小区。 (microbiome 微生物组)
