A briefcase full of poop changed my life.

00:16
Ten years ago, I was a graduate student
1
16810
1880
00:18
and I was helping judge a genetic engineering competition
2
18714
2674
00:21
for undergrads.
3
21412
1221
00:22
There, I met a British artist and designer named Alexandra Daisy Ginsberg.
4
22657
3941
00:26
She was wearing the white embroidered polo shirt
5
26622
2381
00:29
of the University of Cambridge team
6
29027
1729
00:30
and holding a silver briefcase,
7
30780
1580
00:32
like the kind that you would imagine is handcuffed to your wrist.
8
32384
3284
00:35
She gestured over from a quiet corner
9
35692
1784
00:37
and asked me if I wanted to see something.
10
37500
2000
00:39
With a sneaky look, she opened up the suitcase,
11
39803
2230
00:42
and inside were six glorious, multicolored turds.
12
42057
5115
00:47
The Cambridge team, she explained,
13
47609
1674
00:49
had spent their summer engineering the bacteria E. coli
14
49307
2913
00:52
to be able to sense different things in the environment
15
52244
2762
00:55
and produce a rainbow of different colors in response.
16
55030
2944
00:57
Arsenic in your drinking water?
17
57998
1729
00:59
This strain would turn green.
18
59751
1569
01:01
She and her collaborator, the designer James King,
19
61344
2381
01:03
worked with the students and imagined the different possible scenarios
20
63749
3293
01:07
of how you might use these bacteria.
21
67066
1762
01:08
What if, they asked, you could use them
22
68852
2028
01:10
as a living probiotic drink and health monitor, all in one?
23
70904
4286
01:15
You could drink the bacteria and it would live in your gut,
24
75785
2768
01:18
sensing what's going on,
25
78577
1291
01:19
and then in response to something,
26
79892
1628
01:21
it would be able to produce a colored output.
27
81544
2268
01:23
Holy shit!
28
83836
1167
01:25
The Cambridge team went on to win
29
85027
1579
01:26
the International Genetically Engineered Machine competition,
30
86630
2873
01:29
or iGEM for short.
31
89527
1360
01:30
And as for me, those turds were a turning point.
32
90911
3309
01:34
I am a synthetic biologist,
33
94744
1571
01:36
which is probably a weird term that most people aren't familiar with.
34
96339
3278
01:39
It definitely sounds like an oxymoron.
35
99641
2055
01:41
How can biology, something natural,
36
101720
2290
01:44
be synthetic?
37
104034
1167
01:45
How can something artificial be alive?
38
105225
3055
01:48
Synthetic biologists sort of poke holes
39
108788
1915
01:50
in that boundary that we draw between what is natural and what's technological.
40
110727
4279
01:55
And every year, iGEM students from all over the world
41
115030
2650
01:57
spend their summer
42
117704
1214
01:58
trying to engineer biology to be technology.
43
118942
3068
02:02
They teach bacteria how to play sudoku,
44
122034
2715
02:04
they make multicolored spider silk,
45
124773
2868
02:07
they make self-healing concrete
46
127665
2150
02:09
and tissue printers and plastic-eating bacteria.
47
129839
3302
02:13
Up until that moment, though,
48
133165
1396
02:14
I was a little bit more concerned with a different kind of oxymoron.
49
134585
3215
02:18
Just plain old genetic engineering.
50
138180
2056
02:20
The comedian Simon Munnery once wrote
51
140260
2088
02:22
that genetic engineering is actually insulting to proper engineering.
52
142372
4892
02:27
Genetic engineering is more like throwing a bunch of concrete and steel in a river
53
147288
3865
02:31
and if somebody can walk across, you call it a bridge.
54
151177
2790
02:34
And so synthetic biologists were pretty worried about this,
55
154411
2785
02:37
and worried that genetic engineering was a little bit more art that science.
56
157220
3690
02:41
They wanted to turn genetic engineering into a real engineering discipline,
57
161369
4103
02:45
where we could program cells and write DNA
58
165496
3905
02:49
the way that engineers write software for computers.
59
169425
3668
02:53
That day 10 years ago started me on a path that gets me to where I am now.
60
173117
4524
02:57
Today, I'm the creative director
61
177665
1618
02:59
at a synthetic biology company called Ginkgo Bioworks.
62
179307
2824
03:02
"Creative director" is a weird title
63
182433
1721
03:04
for a biotech company were people try to program life
64
184178
2556
03:06
the way that we program computers.
65
186758
2000
03:09
But that day when I met Daisy,
66
189165
2055
03:11
I learned something about engineering.
67
191244
1841
03:13
I learned that engineering isn't really just about equations
68
193109
2840
03:15
and steel and circuits,
69
195973
1777
03:17
it's actually about people.
70
197774
2016
03:19
It's something that people do, and it impacts us.
71
199814
2515
03:22
So in my work,
72
202353
1208
03:23
I try to open up new spaces for different kinds of engineering.
73
203585
3648
03:27
How can we ask better questions,
74
207633
2333
03:29
and can we have better conversations
75
209990
1731
03:31
about what we want from the future of technology?
76
211745
2443
03:34
How can we understand the technological
77
214212
2571
03:36
but also social and political and economic reasons
78
216807
2857
03:39
that GMOs are so polarizing in our society?
79
219688
2770
03:42
Can we make GMOs that people love?
80
222482
2000
03:45
Can we use biology to make technology that's more expansive and regenerative?
81
225315
5624
03:50
I think it starts by recognizing that we, as synthetic biologists,
82
230963
3770
03:54
are also shaped by a culture that values "real engineering"
83
234757
3923
03:58
more than any of the squishy stuff.
84
238704
2000
04:01
We get so caught up in circuits and what happens inside of computers,
85
241561
4029
04:05
that we sometimes lose sight of the magic that's happening inside of us.
86
245614
3642
04:09
There is plenty of shitty technology out there,
87
249280
2638
04:11
but this was the first time that I imagined poop as technology.
88
251942
4468
04:16
I began to see that synthetic biology was awesome,
89
256434
3532
04:19
not because we could turn cells into computers,
90
259990
2762
04:22
but because we could bring technology to life.
91
262776
2809
04:25
This was technology that was visceral,
92
265609
1889
04:27
an unforgettable vision of what the future might hold.
93
267522
3150
04:30
But importantly, it was also framed as the question
94
270696
2453
04:33
"Is this the kind of future that we actually want?"
95
273173
2404
04:35
We've been promised a future of chrome,
96
275601
2476
04:38
but what if the future is fleshy?
97
278101
2881
04:41
Science and science fiction
98
281006
2111
04:43
help us remember that we're made of star stuff.
99
283141
2587
04:45
But can it also help us remember the wonder and weirdness
100
285752
2674
04:48
of being made of flesh?
101
288450
1675
04:50
Biology is us,
102
290149
1285
04:51
it's our bodies, it's what we eat.
103
291458
2206
04:53
What happens when biology becomes technology?
104
293688
3312
04:57
These images are questions,
105
297709
2079
04:59
and they challenge what we think of as normal and desirable.
106
299812
3658
05:03
And they also show us that the future is full of choices
107
303796
2927
05:06
and that we could choose differently.
108
306747
2000
05:09
What's the future of the body, of beauty?
109
309279
3277
05:12
If we change the body, will we have new kinds of awareness?
110
312580
3553
05:16
And will new kinds of awareness of the microbial world
111
316506
2678
05:19
change the way that we eat?
112
319208
1898
05:21
The last chapter of my dissertation was all about cheese that I made
113
321130
3513
05:24
using bacteria that I swabbed from in between my toes.
114
324667
3066
05:28
I told you that the poop changed my life.
115
328244
2190
05:30
I worked with the smell artist and researcher Sissel Tolaas
116
330458
2762
05:33
to explore all of the ways that our bodies and cheese are connected
117
333244
5044
05:38
through smell and therefore microbes.
118
338312
2746
05:41
And we created this cheese
119
341082
1436
05:42
to challenge how we think about the bacteria
120
342542
2932
05:45
that's part of our lives
121
345498
1460
05:46
and the bacteria that we work with in the lab.
122
346982
2476
05:49
We are, indeed, what we eat.
123
349482
2222
05:51
The intersection of biology and technology
124
351728
2190
05:53
is more often told as a story of transcending our fleshy realities.
125
353942
4087
05:58
If you can upload your brain to a computer,
126
358053
2033
06:00
you don't need to poop anymore after all.
127
360110
1968
06:02
And that's usually a story that's told as a good thing, right?
128
362102
3075
06:05
Because computers are clean, and biology is messy.
129
365201
5317
06:10
Computers make sense and are rational,
130
370542
2599
06:13
and biology is an unpredictable tangle.
131
373165
3335
06:17
It kind of follows from there
132
377331
1390
06:18
that science and technology are supposed to be rational,
133
378745
3205
06:21
objective
134
381974
1452
06:23
and pure,
135
383450
1953
06:25
and it's humans that are a total mess.
136
385427
2621
06:28
But like synthetic biologists poke holes
137
388407
2238
06:30
in that line between nature and technology,
138
390669
3032
06:33
artists, designers and social scientists
139
393725
2476
06:36
showed me that the lines that we draw between nature, technology and society
140
396225
4273
06:40
are a little bit softer than we might think.
141
400522
2373
06:42
They challenge us to reconsider our visions for the future
142
402919
3480
06:46
and our fantasies about controlling nature.
143
406423
2937
06:49
They show us how our prejudices, our hopes and our values
144
409384
3587
06:52
are embedded in science and technology
145
412995
2227
06:55
through the questions that we ask and the choices that we make.
146
415246
2983
06:58
They make visible the ways that science and technology are human
147
418253
4348
07:02
and therefore political.
148
422625
1635
07:04
What does it mean for us to be able to control life
149
424284
2484
07:06
for our own purposes?
150
426792
1547
07:08
The artists Oron Catts and Ionat Zurr
151
428363
1849
07:10
made a project called "Victimless Leather,"
152
430236
2135
07:12
where they engineered a tiny leather jacket
153
432395
2888
07:15
out of mouse cells.
154
435307
1469
07:16
Is this jacket alive?
155
436800
2190
07:19
What does it take to grow it and keep it this way?
156
439014
3277
07:22
Is it really victimless?
157
442315
1595
07:23
And what does it mean for something to be victimless?
158
443934
2611
07:27
The choices that we make
159
447022
1214
07:28
in what we show and what we hide in our stories of progress,
160
448260
3500
07:31
are often political choices that have real consequences.
161
451784
3703
07:35
How will genetic technologies shape the way that we understand ourselves
162
455511
4253
07:39
and define our bodies?
163
459788
1429
07:41
The artist Heather Dewey-Hagborg made these faces
164
461241
2598
07:43
based on DNA sequences she extracted from sidewalk litter,
165
463863
3055
07:46
forcing us to ask questions about genetic privacy,
166
466942
3203
07:50
but also how and whether DNA can really define us.
167
470169
3698
07:54
How will we fight against and cope with climate change?
168
474249
3138
07:57
Will we change the way that we make everything,
169
477411
2222
07:59
using biological materials that can grow and decay alongside us?
170
479657
4103
08:03
Will we change our own bodies?
171
483784
2293
08:06
Or nature itself?
172
486101
1841
08:07
Or can we change the system that keeps reinforcing those boundaries
173
487966
4110
08:12
between science, society, nature and technology?
174
492100
3096
08:15
Relationships that today keep us locked in these unsustainable patterns.
175
495220
4341
08:19
How we understand and respond to crises
176
499585
2198
08:21
that are natural, technical and social all at once,
177
501807
3040
08:24
from coronavirus to climate change,
178
504871
2245
08:27
is deeply political,
179
507140
1707
08:28
and science never happens in a vacuum.
180
508871
2706
08:32
Let's go back in time
181
512165
1214
08:33
to when the first European settlers arrived in Hawaii.
182
513403
2529
08:36
They eventually brought their cattle and their scientists with them.
183
516488
3516
08:40
The cattle roamed the hillsides,
184
520028
2175
08:42
trampling and changing the ecosystems as they went.
185
522227
2910
08:45
The scientists catalogued the species that they found there,
186
525161
3468
08:48
often taking the last specimen before they went extinct.
187
528653
3032
08:52
This is the Maui hau kuahiwi,
188
532117
2214
08:54
or the Hibiscadelphus wilderianus,
189
534355
2206
08:56
so named by Gerrit Wilder in 1910.
190
536585
2382
08:59
By 1912, it was extinct.
191
539276
2579
09:01
I found this specimen in the Harvard University Herbarium,
192
541879
3285
09:05
where it's housed with five million other specimens from all over the world.
193
545188
4164
09:09
I wanted to take a piece of science's past,
194
549376
2738
09:12
tied up as it was with colonialism,
195
552138
2158
09:14
and all of the embedded ideas
196
554320
1392
09:15
of the way that nature and science and society should work together,
197
555736
4071
09:19
and ask questions about science's future.
198
559831
2833
09:23
Working with an awesome team at Ginkgo,
199
563109
1905
09:25
and others at UC Santa Cruz,
200
565038
1944
09:27
we were able to extract a little bit of the DNA
201
567006
2603
09:29
from a tiny sliver of this plant specimen
202
569633
2500
09:32
and to sequence the DNA inside.
203
572157
2111
09:34
And then resynthesize a possible version
204
574292
3147
09:37
of the genes that made the smell of the plant.
205
577463
3166
09:40
By inserting those genes into yeast,
206
580653
2373
09:43
we could produce little bits of that smell
207
583050
2513
09:45
and be able to, maybe, smell
208
585587
1738
09:47
a little bit of something that's lost forever.

Working again with Daisy and Sissel Tolaas,
210
589682
2023
09:51
my collaborator on the cheese project,
211
591729
2489
09:54
we reconstructed and composed a new smell of that flower,
212
594242
4034
09:58
and created an installation where people could experience it,
213
598300
3031
10:01
to be part of this natural history and synthetic future.
214
601355
3396
10:06
Ten years ago, I was a synthetic biologist
215
606482
2048
10:08
worried that genetic engineering was more art than science
216
608554
2975
10:11
and that people were too messy
217
611553
1667
10:13
and biology was too complicated.
218
613244
2000
10:15
Now I use genetic engineering as art
219
615641
2960
10:18
to explore all the different ways that we are entangled together
220
618625
3020
10:21
and imagine different possible futures.
221
621669
2230
10:23
A fleshy future
222
623923
1699
10:25
is one that does recognize all those interconnections
223
625646
3296
10:28
and the human realities of technology.
224
628966
2658
10:31
But it also recognizes the incredible power of biology,
225
631927
3512
10:35
its resilience and sustainability,
226
635463
1945
10:37
its ability to heal and grow and adapt.
227
637432
2999
10:40
Values that are so necessary
228
640455
1963
10:42
for the visions of the futures that we can have today.
229
642442
2595
10:45
Technology will shape that future,
230
645061
2310
10:47
but humans make technology.
231
647395
2000
10:49
How we decide what that future will be
232
649696
2613
10:52
is up to all of us.
233

Thank you.
