生命形式：细菌、病毒和霉菌
00:21
Our desks, our computers, our pencils, our buildings
2

4104
我们的书桌、计算机、笔、建筑
00:25
all harbor resident microbial landscapes.
3
13698
3456
全是微生物的栖息地
00:29
As we design these things, we could be thinking
4
17154
2760
当我们设计这些物品时，不妨思考一下
00:31
about designing these invisible worlds,
5
19914
2814
关于这些隐形世界的设计
00:34
and also thinking about how they interact
6
22728
2243
同时思考它们如何与
00:36
with our personal ecosystems.
7
24971
2756
我们个人的生态系统互动
00:39
Our bodies are home to trillions of microbes,
8
27727
3643
我们的身体是亿万个微生物的住所
00:43
and these creatures define who we are.
9
31370
2360
这些生物定义了我们
00:45
The microbes in your gut can influence your weight and your moods.
10
33730
3878
肠道中的微生物可影响你的体重和心情
00:49
The microbes on your skin can help boost your immune system.
11
37608
3458
皮肤上的微生物有助于提升你的免疫系统
00:53
The microbes in your mouth can freshen your breath,
12
41066
3009
口中的微生物可使你口气清新
00:56
or not,
13
44075
1472
或正好相反
00:57
and the key thing is that our personal ecosystems
14
45547
2979
最重要的是，我们个人的生态系统
01:00
interact with ecosystems on everything we touch.
15
48526
3068
与我们接触的一切生态系统间的交互作用
01:03
So, for example, when you touch a pencil,
16
51594
1592
因此，例如，当你触摸一支笔时
01:05
microbial exchange happens.
17
53186
2832
即发生微生物交换
01:08
If we can design the invisible ecosystems in our surroundings,
18
56018
4896
如果我们能设计周遭的隐形生态系统
01:12
this opens a path to influencing
19
60914
2623
将开启一条途径
01:15
our health in unprecedented ways.
20
63537
3391
以前所未有的方式影响我们的健康
01:18
I get asked all of the time from people,
21
66928
2464
经常有人问我
01:21
"Is it possible to really design microbial ecosystems?"
22
69392
4070
“设计微生物生态系统是否确实可行？”
01:25
And I believe the answer is yes.
23
73462
2548
我认为答案是肯定的
01:28
I think we're doing it right now,
24
76010
1925
我认为我们此刻正在进行这件事
01:29
but we're doing it unconsciously.
25
77935
3108
但处于不自觉状态
01:33
I'm going to share data with you
26
81043
1965
我想与大家分享一些信息
01:35
from one aspect of my research focused on architecture
27
83008
3728
来自我对建筑的研究之一
01:38
that demonstrates how, through both conscious
28
86736
3126
显示我们如何藉由有意识
01:41
and unconscious design,
29
89862
2210
及无意识的设计
01:44
we're impacting these invisible worlds.
30
92072
3009
影响这些肉眼不可见的世界
01:47
This is the Lillis Business Complex at the University of Oregon,
31
95081
4229
这是奥勒冈大学Lillis商学综合大楼
01:51
and I worked with a team of architects and biologists
32
99310
2684
我与一个由
建筑师和生物学家组成的团队合作
建筑师和生物学家组成的团队合作
01:53
to sample over 300 rooms in this building.
33
101994
4174
在这栋建筑中的300多个房间取样
01:58
We wanted to get something like a fossil record of the building,
34
106168
4010
我们希望得到
类似建筑物化石纪录的数据
类似建筑物化石纪录的数据
02:02
and to do this, we sampled dust.
35
110178
3310
为了达成这个目标，我们搜集灰尘样本
02:05
From the dust, we pulled out bacterial cells,
36
113488
3908
我们从灰尘中分离出细菌细胞
02:09
broke them open, and compared their gene sequences.
37
117396
3404
将它们打破，比较其中的基因序列
02:12
This means that people in my group
38
120800
1727
这意味着我的团队成员
02:14
were doing a lot of vacuuming during this project.
39
122527
3313
在这个计划中进行了许多吸尘工作
02:17
This is a picture of Tim, who,
40
125840
2520
照片中的人是Tim
02:20
right when I snapped this picture, reminded me,
41
128360
2454
就在拍摄这张照片的当下，他提醒我－
02:22
he said, "Jessica, the last lab group I worked in
42
130814
2570
他说，“Jessica，在上个研究团队中”
02:25
I was doing fieldwork in the Costa Rican rainforest,
43
133384
2971
“我的工作是
在哥斯达黎加雨林进行田野调查”
在哥斯达黎加雨林进行田野调查”
02:28
and things have changed dramatically for me."
44
136355
3757
“对我来说
目前的处境简直是天壤之别”
目前的处境简直是天壤之别”
02:32
So I'm going to show you now first what we found in the offices,
45
140112
3752
因此我准备向大家展示
我们在办公室中的第一项发现
我们在办公室中的第一项发现
02:35
and we're going to look at the data through a visualization tool
46
143864
3076
我们将藉由某种视觉工具浏览这些数据
02:38
that I've been working on in partnership with Autodesk.
47
146940
3540
这是我和Autodesk
（3D软件设计公司）长期合作的成果
（3D软件设计公司）长期合作的成果
02:42
The way that you look at this data is,
48
150480
2472
浏览数据的方法是
02:44
first, look around the outside of the circle.
49
152952
3578
先观察圆圈外围
02:48
You'll see broad bacterial groups,
50
156530
3022
你将看见许多不同的菌落
02:51
and if you look at the shape of this pink lobe,
51
159552
2840
如果观察这个粉红叶片状图形
02:54
it tells you something about the relative abundance of each group.
52
162392
3016
它将显示每种菌落的相对数量
02:57
So at 12 o'clock, you'll see that offices have a lot of
53
165408
2496
因此在12点钟方向
你看见办公室存在许多
你看见办公室存在许多
02:59
alphaproteobacteria, and at one o'clock
54
167904
2561
甲型变形菌，在1点钟方向
03:02
you'll see that bacilli are relatively rare.
55
170465
4195
你看见杆菌数量十分稀少
03:06
Let's take a look at what's going on in different space types in this building.
56
174660
4363
我们看看建筑中不同类型空间的情况
03:11
If you look inside the restrooms,
57
179023
2022
如果观察休息室
03:13
they all have really similar ecosystems,
58
181045
3130
它们的生态系统均十分相似
03:16
and if you were to look inside the classrooms,
59
184175
2328
如果观察教室
03:18
those also have similar ecosystems.
60
186503
2866
它们亦拥有相似的生态系统
03:21
But if you look across these space types,
61
189369
2414
但如果纵观这些空间类型
03:23
you can see that they're fundamentally different
62
191783
2397
可看出它们彼此间
03:26
from one another.
63
194180
2155
截然不同
03:28
I like to think of bathrooms like a tropical rainforest.
64
196335
2993
我喜欢将浴室想成热带雨林
03:31
I told Tim, "If you could just see the microbes,
65
199328
2487
我对Tim说，“如果你能看见微生物”
03:33
it's kind of like being in Costa Rica. Kind of."
66
201815
4039
“感觉就像身处哥斯达黎加，多少吧”
03:37
And I also like to think of offices as being a temperate grassland.
67
205854
4523
我也喜欢将办公室想成温带草原
03:42
This perspective is a really powerful one for designers,
68
210377
4212
这个观点对设计师来说十分有用
03:46
because you can bring on principles of ecology,
69
214589
3427
因为你可套用生态学原则
03:50
and a really important principle of ecology is dispersal,
70
218016
2912
生态学中一个十分重要的原则就是分布
03:52
the way organisms move around.
71
220928
2727
即有机体的传播方式
03:55
We know that microbes are dispersed around by people
72
223655
4184
我们知道微生物藉由人类
03:59
and by air.
73
227839
1071
和空气传播
04:00
So the very first thing we wanted to do in this building
74
228910
2837
因此我们希望在这栋建筑中做的第一件事
04:03
was look at the air system.
75
231747
1853
就是观察空气系统
04:05
Mechanical engineers design air handling units
76
233600
3232
机械工程师设计空调系统
04:08
to make sure that people are comfortable,
77
236832
2192
确保人们感到舒适
04:11
that the air flow and temperature is just right.
78
239024
2553
空气流通、气温恰到好处
04:13
They do this using principles of physics and chemistry,
79
241577
3544
他们利用物理和化学原理进行这项工作
04:17
but they could also be using biology.
80
245121
4374
但也可利用生物学
04:21
If you look at the microbes
81
249495
2112
如果观察这栋建筑中
04:23
in one of the air handling units in this building,
82
251607
3050
某个空调系统里的微生物
04:26
you'll see that they're all very similar to one another.
83
254657
3991
将发现其中生态均十分相似
04:30
And if you compare this to the microbes
84
258648
3535
如果将它与
04:34
in a different air handling unit,
85
262183
2144
不同空调系统中的微生物比较
04:36
you'll see that they're fundamentally different.
86
264327
2712
将发现两者截然不同
04:39
The rooms in this building are like islands in an archipelago,
87
267039
3551
这建筑中的房间就像孤立群岛中的岛屿
04:42
and what that means is that mechanical engineers
88
270590
2857
这意味着机械工程师
04:45
are like eco-engineers, and they have the ability
89
273447
2676
如同生态工程师，有能力
04:48
to structure biomes in this building the way that they want to.
90
276123
5584
以他们想要的方式
建构这栋建筑中的生物群落
建构这栋建筑中的生物群落
04:53
Another facet of how microbes get around is by people,
91
281707
4108
另一个传播微生物的方式是藉由人类
04:57
and designers often cluster rooms together
92
285815
3167
设计师通常将房间设计在一处
05:00
to facilitate interactions among people,
93
288982
2055
促进人们的交流
05:03
or the sharing of ideas, like in labs and in offices.
94
291037
3472
或分享彼此的看法，就像实验室和办公室
05:06
Given that microbes travel around with people,
95
294509
2674
考虑微生物随着人们四处传播
05:09
you might expect to see rooms that are close together
96
297183
2673
你或许预期相距不远的房间
05:11
have really similar biomes.
97
299856
2255
存在十分相似的生物群落
05:14
And that is exactly what we found.
98
302111
2480
这正是我们发现的结果
05:16
If you look at classrooms right adjacent to one another,
99
304591
3167
如果观察彼此相邻的教室
05:19
they have very similar ecosystems,
100
307758
2199
它们拥有十分相似的生态系统
05:21
but if you go to an office
101
309957
3139
但如果观察
05:25
that is a farther walking distance away,
102
313096
3048
与其相距甚远的办公室
05:28
the ecosystem is fundamentally different.
103
316144
2736
其中的生态系统则大不相同
05:30
And when I see the power that dispersal has
104
318880
4545
当我发现促使
05:35
on these biogeographic patterns,
105
323425
2280
生物地理学分布的力量之后
05:37
it makes me think that it's possible
106
325705
2559
意识到或许可藉此
05:40
to tackle really challenging problems,
107
328264
3736
解决一些充满挑战的问题
05:44
like hospital-acquired infections.
108
332000
2461
例如医院内感染
05:46
I believe this has got to be, in part,
109
334461
2606
我认为其中部分原因必定在于
05:49
a building ecology problem.
110
337067
3643
建筑物的生态问题
05:52
All right, I'm going to tell you one more story about this building.
111
340710
3792
好，我将告诉大家
更多关于这栋建筑的故事
更多关于这栋建筑的故事
05:56
I am collaborating with Charlie Brown.
112
344502
3465
我与Charlie Brown合作
05:59
He's an architect,
113
347967
1541
他是一名建筑师
06:01
and Charlie is deeply concerned about global climate change.
114
349508
5333
Charlie十分关切全球气候变化
06:06
He's dedicated his life to sustainable design.
115
354841
2944
毕生致力于永续建筑设计
06:09
When he met me and realized that it was possible for him
116
357785
3096
当他遇上我之后，意识到自己有机会
06:12
to study in a quantitative way
117
360881
2176
以量化方式进行研究
06:15
how his design choices impacted
118
363057
2576
了解他的设计选择如何影响
06:17
the ecology and biology of this building,
119
365633
2960
这栋建筑的生态和生物系统
06:20
he got really excited, because it added a new dimension to what he did.
120
368593
4509
他十分兴奋，因为
这为他的工作增添一个新层面
这为他的工作增添一个新层面
06:25
He went from thinking just about energy
121
373102
1868
他从仅思考能源问题
06:26
to also starting to think about human health.
122
374970
3488
转为同时将人类健康纳入考虑
06:30
He helped design some of the air handling systems
123
378458
3861
他协助设计了一些
06:34
in this building and the way it was ventilated.
124
382319
2194
这栋建筑的空调系统及通风方式
06:36
So what I'm first going to show you is
125
384513
2722
因此我首先要展示的是
06:39
air that we sampled outside of the building.
126
387235
3559
我们从户外取样的空气
06:42
What you're looking at is a signature of bacterial communities
127
390794
4167
图中显示的是户外空气中的细菌群落
06:46
in the outdoor air, and how they vary over time.
128
394961
3976
以及它们如何随时间改变
06:50
Next I'm going to show you what happened
129
398937
2988
接下来我将向大家展示
06:53
when we experimentally manipulated classrooms.
130
401925
3649
我们以教室进行实验的情形
06:57
We blocked them off at night
131
405574
1615
我们于夜间将它关闭
06:59
so that they got no ventilation.
132
407189
2266
因此教室无法通风
07:01
A lot of buildings are operated this way,
133
409455
2177
许多建筑采用这种方式
07:03
probably where you work,
134
411632
1751
或许你的工作地点正是如此
07:05
and companies do this to save money on their energy bill.
135
413383
2971
公司藉由这种方式节省电费
07:08
What we found is that these rooms remained relatively stagnant
136
416354
3927
我们发现这些房间的空气几乎静止不动
07:12
until Saturday, when we opened the vents up again.
137
420281
3059
直到我们周六再次将它打开
07:15
When you walked into those rooms,
138
423340
1582
当你走进那些房间时
07:16
they smelled really bad,
139
424922
1975
气味十分难闻
07:18
and our data suggests that it had something to do with
140
426897
3102
我们的数据显示
07:21
leaving behind the airborne bacterial soup
141
429999
3067
这和空气中残留的菌落有关
07:25
from people the day before.
142
433066
2679
来自前一天于此活动的人们
07:27
Contrast this to rooms
143
435745
2172
相较于
07:29
that were designed using a sustainable passive design strategy
144
437917
4281
采用被动式永续策略设计的房间
07:34
where air came in from the outside through louvers.
145
442198
3780
户外空气可由百叶窗进入
07:37
In these rooms, the air tracked the outdoor air relatively well,
146
445978
4797
这些房间的空气成分与户外空气极为相似
07:42
and when Charlie saw this, he got really excited.
147
450775
2135
目赌这个结果时，Charlie非常兴奋
07:44
He felt like he had made a good choice
148
452910
2111
他感到自己藉由设计
07:47
with the design process
149
455021
1734
做了一个好选择
07:48
because it was both energy efficient
150
456755
2395
因为这不仅符合能源效率需求
07:51
and it washed away the building's resident microbial landscape.
151
459150
5289
也能带走残留在建筑中的微生物
07:56
The examples that I just gave you are about architecture,
152
464439
3042
我刚刚展示的是关于建筑的例子
07:59
but they're relevant to the design of anything.
153
467481
2513
但这和任何设计都息息相关
08:01
Imagine designing with the kinds of microbes that we want
154
469994
4170
想象我们希望设计的微生物种类

ABOUT THE SPEAKER
Jessica Green - Engineer and biodiversity scientistJessica Green wants people to understand the important role microbes play in every facet of our lives: climate change, building ecosystems, human health, even roller derby -- using nontraditional tools like art, animation and film to help people visualize the invisible world.
Why you should listen
Jessica Green, a TED2010 Fellow and TED2011 Senior Fellow, is an engineer and ecologist who specializes in biodiversity theory and microbial systems. As a professor at both the University of Oregon and the Santa Fe Institute, she is the founding director of the innovative Biology and the Built Environment (BioBE) Center that bridges biology and architecture.
Green envisions a future with genomic-driven approaches to architectural design that promote sustainability, human health and well-being. She is spearheading efforts to model buildings as complex ecosystems that house trillions of diverse microorganisms interacting with each other, with humans, and with their environment. This framework uses next-generation sequencing technology to characterize the “built environment microbiome” and will offer site-specific design solutions to minimize the spread of infectious disease and maximize building energy efficiency.
