  • These bacteria are not passive riders, these are incredibly important, they keep us alive.
  • 这些细菌不是顺从的乘客,他们难以置信得重要,他们让我们活着。
  • They cover us in an invisible body armor that keeps environmental insults out so that we stay healthy.
  • 它们是我们身上的无形盔甲,阻断来之环境的伤,保持我们的健康。
  • They digest our food, they make our vitamins, they actually educate your immune system to keep bad microbes out.
  • 它们消化食物,制造维他命,它们还指导你的免疫系统将有害微生物阻挡在体外。
  • So they do all these amazing things that help us and are vital for keeping us alive, and they never get any press for that.
  • 它们尽心尽职干活,帮助我们,维护我们的生命,却从没有因此得到过报道。
  • But they get a lot of press because they do a lot of terrible things as well.
  • 反而却因为它们同时做的许多坏事而时常见报。
  • So, there's all kinds of bacteria on the Earth that have no business being in you or on you at any time,
  • 地球上有无数种细菌,有些在任何时候都绝对不应该出现在你的体内体表,
  • and if they are, they make you incredibly sick.
  • 然而假如你不幸遇到了,那你一定会病得很厉害。
  • And so, the question for my lab is whether you want to think about all the good things that bacteria do, or all the bad things that bacteria do.
  • 所以, 我们实验室研究的问题是,正是你想知道的,细菌做的所有好事或者细菌做的所有坏事。
  • The question we had is how could they do anything at all?
  • 我们曾经提出一个疑问: 它们究竟是怎么做到的?
  • I mean they're incredibly small, you have to have a microscope to see one.
  • 我指的是,它们是那么细微,用显微镜才能看到一个。
  • They live this sort of boring life where they grow and divide, and they've always been considered to be these asocial reclusive organisms.
  • 它们的生活好像只是单调乏味的成长与分裂,而且长久以来被认为是不善社交的隐居生命体。
  • And so it seemed to us that they are just too small to have an impact on the environment if they simply act as individuals.
  • 所以在我们看来,它们实在是太渺小,如果单枪匹马,根本到无法对环境产生任何影响。
  • And so we wanted to think if there couldn't be a different way that bacteria live.
  • 所以我们正在探讨细菌是不是有着特殊的生存方式。
  • And the clue to this came from another marine bacterium, and it's a bacterium called Vibrio fischeri.
  • 解答这个问题的线索,来自一种叫做费氏弧菌的海洋细菌。
  • And what you're looking at on this slide is just a person from my lab holding a flask of a liquid culture of a bacterium,
  • 你们在这张幻灯看到的,是我实验室的一个工作人员握着一瓶装满这种细菌的培养液,
  • a harmless beautiful bacterium that comes from the ocean, named Vibrio fischeri.
  • 这是一种来自海洋的、美丽而且无害的细菌,叫做费氏弧菌。
  • And this bacterium has the special property that it makes light, so it makes bioluminescence, like fireflies make light.
  • 这种细菌的特性是会发光,产生生物荧光,像萤火虫一样。
  • So we're not doing anything to the cells here.
  • 我们没有对这些细胞做任何处理。
  • We just took the picture by turning the lights off in the room, and this is what we see.
  • 我们只是把房间灯关了,然后照了这张照片,这是我们所见到的情形。
