00:13
I want you to touch your face.
0
13110
1710
Želim da si dotaknete lice.
00:15
Go on.
1
15406
1271
Slobodno.
00:17
What do you feel?
2
17406
1403
Što osjećate?
00:18
Soft? Squishy?
3
18833
1883
Mekano? Gnjecavo?
00:21
It's you, right? You're feeling you?
4
21313
2610
To ste vi, zar ne? Osjećate sebe?
00:24
Well, it's not quite true.
5
24929
1703
Pa, to nije posve točno.
00:27
You're actually feeling thousands of microscopic creatures
6
27207
3245
Zapravo osjećate na tisuće mikroskopskih stvorenja
00:30
that live on our face and fingers.
7
30476
2541
koja žive na vašem licu i prstima.
00:34
You're feeling some of the fungi
8
34301
1722
Osjećate neke od gljivica
00:36
that drifted down from the air ducts today.
9
36047
2880
koje su danas doletjele zračnim kanalima.
00:38
They set off our allergies
10
38951
1967
Stvaraju alergije
00:40
and smell of mildew.
11
40942
1552
i mirišu na plijesan.
00:43
You're feeling some of the 100 billion bacterial cells
12
43865
4144
Osjećate neke od 100 milijardi bakterijskih stanica
00:48
that live on our skin.
13
48033
1646
koje žive na našoj koži.
00:50
They've been munching away at your skin oils and replicating,
14
50273
3906
Grickaju masnoću s vaše kože, množe se,
00:54
producing the smells of body odor.
15
54203
2262
proizvodeći tjelesne mirise.
00:57
You're likely even touching the fecal bacteria
16
57384
2915
Vjerojatno dodirujete i fekalne bakterije
01:00
that sprayed onto you the last time you flushed a toilet,
17
60323
3660
koje su doletjele na vas zadnji put kada ste pustili vodu u zahodu,
01:04
or those bacteria that live in our water pipes
18
64007
3124
ili one bakterije koje žive u vodovodnim cijevima,
01:07
and sprayed onto you with your last shower.
19
67155
2459
koje su vas poprskale za posljednjeg tuširanja.
01:10
Sorry.
20
70486
1151
Žao mi je.
01:11
(Laughter)
21
71661
1468
(Smijeh)
01:13
You're probably even giving a microscopic high five
22
73153
3564
Vjerojatno dajete mikroskopski pet
01:16
to the two species of mites that live on our faces,
23
76741
3725
dvjema vrstama grinja koje žive na našim licima,
01:20
on all of our faces.
24
80490
1668
na licima svih nas.
01:22
They've spent the night squirming across your face
25
82697
2646
Provele su noć migoljeći se uzduž vašeg lica
01:25
and having sex on the bridge of your nose.
26
85367
2848
i seksajući se na vrhu vašeg nosa.
01:28
(Laughter)
27
88239
2590
(Smijeh)
01:31
Many of them are now leaking their gut contents onto your pores.
28
91790
4162
Mnoge od njih sada ispuštaju sadržaj svojih crijeva na vaše pore.
01:35
(Laughter)
29
95976
2056
(Smijeh)
01:38
Now look at your finger.
30
98056
1464
Sad pogledajte svoj prst.
01:40
How's it feel? Gross?
31
100186
2101
Kakav je osjećaj? Ljigav?
01:42
In desperate need of soap or bleach?
32
102311
2380
Očajnički treba sapun ili izbjeljivač?
01:46
That's how you feel now,
33
106192
1614
Tako se sada osjećate,
01:47
but it's not going to be how you feel in the future.
34
107830
2612
ali nećete se tako osjećati ubuduće.
01:51
For the last 100 years,
35
111274
1925
Posljednjih stotinu godina
01:53
we've had an adversarial relationship
36
113223
1977
imali smo neprijateljsku vezu
01:55
with the microscopic life nearest us.
37
115224
2615
s mikroskopskim životom u našoj neposrednoj blizini.
01:57
If I told you there was a bug in your house
38
117863
2122
Da sam vam rekla da je buba u vašoj kući
02:00
or bacteria in your sink,
39
120009
1234
ili bakterija u sudoperu,
02:01
there was a human-devised solution for that,
40
121267
2327
postojalo bi ljudsko rješenje za to,
02:03
a product to eradicate, exterminate,
41
123618
3136
proizvod koji će istrijebiti, potamaniti,
02:06
disinfect.
42
126778
1293
dezinficirati.
02:08
We strive to remove most of the microscopic life in our world now.
43
128663
3875
Danas težimo uklanjanju većine mikroskopskog života u našem svijetu.
02:13
But in doing so, we're ignoring the best source of new technology
44
133642
4693
No, čineći to, zanemarujemo najbolji izvor nove tehnologije
02:18
on this planet.
45
138359
1216
na ovom planetu.
02:20
The last 100 years have featured human solutions to microbial problems,
46
140444
5646
U posljednjih 100 godina svjedočili smo ljudskim rješenjima mikrobnih problema,
02:26
but the next 100 years will feature microbial solutions to human problems.
47
146114
5464
no u sljedećih 100 bit ćemo svjedoci mikrobnih rješenja za ljudske probleme.
02:32
I'm a scientist, and I work with researchers
48
152331
2369
Znanstvenica sam i radim s istraživačima
02:34
at North Carolina State University and the University of Colorado
49
154724
3276
na državnom sveučilištu Sjeverne Karoline i na Sveučilištu u Coloradu,
02:38
to uncover the microscopic life that is nearest us,
50
158024
3594
kako bismo otkrili mikroskopski život koji nam je najbliži,
02:42
and that's often in our most intimate and boring environments,
51
162637
3868
a to je često u našem najintimnijem i najdosadnijem okruženju,
02:46
be it under our couches, in our backyards,
52
166529
3158
bilo to ispod kauča, u dvorištu,
02:49
or in our belly buttons.
53
169711
1419
ili pupku.
02:51
I do this work because it turns out that we know very little
54
171903
2870
Radim na ovome jer se ispostavilo da jako malo znamo
02:54
about the microscopic life that's nearest us.
55
174797
2321
o mikroskopskom životu koji nam je tako blizu.
02:58
As of a few years ago, no scientist could tell you
56
178101
2473
Do nedavno nijedan znanstvenik nije vam mogao reći
03:00
what bugs or microorganisms live in your home --
57
180598
2613
koji kukci ili mikroorganizmi žive u vašem domu -
03:04
your home, the place you know better than anywhere else.
58
184328
3423
u vašem domu, mjestu koje najbolje poznajete.
03:08
And so I and teams of others
59
188427
1740
Tako sam ja s timovima drugih,
03:10
are armed with Q-tips and tweezers
60
190191
2193
naoružana štapićima za uši, pincetama
03:12
and advanced DNA techniques
61
192408
1866
i naprednim tehnikama DNK,
03:14
to uncover the microscopic life nearest us.
62
194298
2592
kako bismo otkrili taj mikroskopski život.
03:18
In doing so, we found over 600 species of bugs
63
198042
4060
Čineći to, našli smo preko 600 vrsta kukaca
03:22
that live in USA homes,
64
202126
1900
koji žive u američkim domovima,
03:24
everything from spiders and cockroaches
65
204050
2497
od paukova i žohara,
03:26
to tiny mites that cling to feathers.
66
206571
2568
do sitnih grinja koje se drže za perje.
03:29
And we found over 100,000 species of bacteria and fungi
67
209910
5325
Našli smo preko 100.000 vrsta bakterija i gljivica
03:35
that live in our dust bunnies,
68
215259
2015
koje žive u našoj prašini,
03:37
thousands more that live on our clothes or in our showers.
69
217298
3534
još na tisuće njih koje žive u našoj odjeći ili tušu.
03:42
We've gone further still,
70
222146
1544
Išli smo i korak dalje
03:43
and we looked at the microorganisms
71
223714
1716
te proučavali mikroorganizme
03:45
that live inside the bodies of each of those bugs in our home.
72
225454
4128
koji žive u tijelima svih kukaca u našem domu.
03:50
In each bug, for example, a wasp,
73
230328
3410
U svakom kukcu, primjerice, u osi,
03:53
we see a microscopic jungle unfold in a petri plate,
74
233762
4210
vidimo mikroskopsku džunglu u Petrijevoj zdjelici,
03:57
a world of hundreds of vibrant species.
75
237996
3277
svijet stotina živahnih vrsta.
04:01
Behold the biological cosmos!
76
241297
2453
Pogledajte biološki kozmos!
04:05
So many of the species you're looking at right now
77
245351
2429
Mnoge vrste koje sada gledate
04:07
don't yet have names.
78
247804
1227
još nemaju ni ime.
04:09
Most of the life around us remains unknown.
79
249723
2823
Većina života oko nas ostaje nepoznata.
04:13
I remember the first time I discovered and got to name a new species.
80
253650
3503
Sjećam se svog prvog otkrića i imenovanja nove vrste.
04:17
It was a fungus that lives in the nest of a paper wasp.
81
257177
3494
Bila je to gljivica koja živi u gnijezdu papirne ose.
04:20
It's white and fluffy,
82
260695
2225
Bijela je i čupava
04:22
and I named it "mucor nidicola,"
83
262944
2544
i nazvala sam je "mucor nidicola,"
04:25
meaning in Latin that it lives in the nest of another.
84
265512
3003
što na latinskom znači da živi u tuđem gnijezdu.
04:29
This is a picture of it growing on a dinosaur,
85
269772
2844
Ovo je slika te gljivice kako raste na dinosauru
04:32
because everyone thinks dinosaurs are cool.
86
272640
3097
jer svi misle da su dinosauri "kul".
04:36
At the time, I was in graduate school,
87
276506
2316
U to vrijeme, bila sam na početku studija
04:38
and I was so excited that I had found this new life form.
88
278846
3722
i jako uzbuđena jer sam našla taj novi oblik života.
04:42
I called up my dad, and I go,
89
282592
1776
Nazvala sam tatu i rekla,
04:44
"Dad! I just discovered a new microorganism species."
90
284392
3418
"Tata! Upravo sam otkrila novu vrstu mikroorganizma."
04:48
And he laughed and he goes,
91
288394
1501
Nasmijao se i odgovorio mi,
04:49
"That's great. I hope you also discovered a cure for it."
92
289919
3268
"Odlično. Nadam se da si našla i lijek za nju."
04:53
(Laughter)
93
293211
1446
(Smijeh)
04:54
"Cure it."
94
294681
1172
"Lijek."
04:57
Now, my dad is my biggest fan,
95
297022
2707
Moj tata je moj najveći obožavatelj,
04:59
so in that crushing moment where he wanted to kill my new little life form,
96
299753
4370
pa u tom trenutku kad je htio da ubijem svoj novi mali oblik života,
05:04
I realized that actually I had failed him,
97
304147
2546
shvatila sam da sam ga zapravo iznevjerila
05:06
both as a daughter and a scientist.
98
306717
2161
kao kćer i znanstvenica.
05:08
In my years toiling away in labs and in people's backyards,
99
308902
3926
Tijekom godina mukotrpnog rada u laboratorijima i dvorištima,
05:12
investigating and cataloging the microscopic life around us,
100
312852
3680
dok sam istraživala i popisivala mikroskopski život oko nas,
05:16
I'd never made clear my true mission to him.
101
316556
2536
nikad mu nisam objasnila svoju pravu misiju.
05:20
My goal is not to find technology
102
320264
1916
Moj cilj nije naći tehnologiju
05:22
to kill the new microscopic life around us.
103
322204
2400
koja će ubiti mikroskopski život koji nas okružuje.
05:25
My goal is to find new technology from this life, that will help save us.
104
325135
4132
Moj cilj je naći novu tehnologiju u tome životu, koji će nas spasiti.
05:31
The diversity of life in our homes is more than a list of 100,000 new species.
105
331315
5752
Raznolikost života u našim domovima više je od liste od 100.000 novih vrsta.
05:37
It is 100,000 new sources of solutions to human problems.
106
337091
3968
To je 100.000 novih izvora rješenja ljudskih problema.
05:42
I know it's hard to believe that anything that's so small
107
342268
2701
Znam da je teško vjerovati da išta tako sitno
05:44
or only has one cell
108
344993
1158
ili jednostanično
05:46
can do anything powerful,
109
346175
1319
može biti tako moćno,
05:47
but they can.
110
347518
1337
ali može.
05:48
These creatures are microscopic alchemists,
111
348879
2845
Ova bića su mikroskopski alkemičari,
05:51
with the ability to transform their environment
112
351748
2858
sposobni promijeniti svoje okruženje
05:54
with an arsenal of chemical tools.
113
354630
2319
arsenalom kemijskih sredstava.
05:57
This means that they can live anywhere on this planet,
114
357745
2983
To znači da mogu živjeti bilo gdje na ovom planetu
06:00
and they can eat whatever food is around them.
115
360752
2387
i mogu jesti bilo što oko sebe.
06:04
This means they can eat everything from toxic waste to plastic,
116
364372
4309
To znači da mogu jesti sve, od toksičnog otpada to plastike
06:09
and they can produce waste products like oil and battery power
117
369895
4515
i mogu proizvoditi otpad kao što je ulje i baterijski pogon
06:14
and even tiny nuggets of real gold.
118
374434
2842
pa čak i sitne komadiće pravog zlata.
06:18
They can transform the inedible into nutritive.
119
378549
3561
Oni nejestivo mogu pretvoriti u hranjivo.
06:22
They can make sugar into alcohol.
120
382567
2382
Šećer mogu pretvoriti u alkohol.
06:25
They give chocolate its flavor,
121
385746
1913
Oni čokoladi daju okus,
06:27
and soil the power to grow.
122
387683
1736
a tlu snagu za rast.
06:30
I'm here to tell you
123
390273
1167
Ovdje sam da vam kažem
06:31
that the next 100 years will feature these microscopic creatures
124
391464
3147
da ćemo sljedećih 100 godina gledati kako ova mikroskopska bića
06:34
solving more of our problems.
125
394635
1605
rješavaju naše probleme.
06:36
And we have a lot of problems to choose from.
126
396780
2273
Imamo problema na pretek.
06:39
We've got the mundane: bad-smelling clothes or bland food.
127
399582
3927
Imamo one dosadne: smrdljivu odjeću ili bezukusnu hranu.
06:44
And we've got the monumental:
128
404284
2037
Imamo i one ogromne:
06:46
disease, pollution, war.
129
406345
3301
bolest, zagađenje, rat.
06:51
And so this is my mission:
130
411146
1684
Ovo je moja misija:
06:52
to not just catalog the microscopic life around us,
131
412854
3230
ne samo popisati mikroskopski život koji nas okružuje,
06:56
but to find out what it's uniquely well-suited to help us with.
132
416108
3249
nego naći i ono jedinstveno što nam odgovara, kako bi nam pomoglo.
07:00
Here's an example.
133
420501
1365
Evo primjer.
07:01
We started with a pest,
134
421890
1632
Započeli smo sa štetočinom,
07:03
a wasp that lives on many of our homes.
135
423546
2348
osom koja živi u domovima mnogih od nas.
07:06
Inside that wasp, we plucked out a little-known microorganism species
136
426527
4927
Iz te ose iščupali smo slabo znanu vrstu mikroorganizma,
07:11
with a unique ability:
137
431478
1389
jedinstvenu po tome
07:13
it could make beer.
138
433595
1235
što može stvarati pivo.
07:15
This is a trait that only a few species on this planet have.
139
435706
3525
Ovo je osobina koju ima samo nekoliko vrsta na planetu.
07:19
In fact, all commercially produced beer you've ever had
140
439255
2861
Zapravo, sva komercijalna piva koja ste ikad kušali,
07:22
likely came from one of only three microorganism species.
141
442140
3503
vjerojatno su potekla od jedne od samo tri vrste mikroorganizama.
07:26
Yet our species, it could make a beer that tasted like honey,
142
446549
4082
No, naša vrsta može utjecati na to da pivo ima okus meda
07:31
and it could also make a delightfully tart beer.
143
451416
2642
ili da stvori izvrsno tart pivo.
07:34
In fact, this microorganism species that lives in the belly of a wasp,
144

Zapravo, ova vrsta mikroorganizma koja živi u trbuhu ose,
07:39
it could make a valuable sour beer
145
459427
2297
može napraviti kiselo pivo
07:41
better than any other species on this planet.
146
461748
3459
bolje nego ijedna druga vrsta na ovom planetu.
07:46
There are now four species that produce commercial beer.
147
466496
3124
Trenutno postoje četiri vrste koje proizvode komercijalno pivo.
07:51
Where you used to see a pest,
148
471017
2315
Dosad ste vidjeli štetočinu,
07:53
now think of tasting your future favorite beer.
149
473356
2937
a sad pomislite na kušanje vašeg budućeg najdražeg piva.
07:57
As a second example,
150
477745
1529
Za drugi primjer,
07:59
I worked with researchers to dig in the dirt in people's backyards.
151
479298
3356
radila sam s istraživačima i kopala po prljavštini tuđih dvorišta.
08:03
There, we uncovered a microorganism that could make novel antibiotics,
152
483313
4057
Otkrili smo mikroorganizam koji može sačinjavati nove antibiotike,
08:07
antibiotics that can kill the world's worst superbugs.
153
487394
3133
antibiotike koji mogu ubiti najgore superkukce svijeta.
08:11
This was an awesome thing to find,
154
491510
3209
To je bilo odlično otkriće,
08:14
but here's the secret:
155
494743
1378
ali evo tajne:
08:16
for the last 60 years,
156
496984
1920
posljednjih 60 godina,
08:18
most of the antibiotics on the market
157
498928
2289
većina antibiotika na tržištu
08:21
have come from similar soil bacteria.
158
501241
2209
potekla je od slične bakterije iz tla.
08:24
Every day, you and I and everyone in this room
159
504089
3025
Svaki dan, vas, mene i sve u ovoj prostoriji
08:27
and on this planet,
160
507138
1742
i na ovom planetu,
08:28
are saved by similar soil bacteria that produce most of our antibiotics.
161
508904
4419
spašava slična bakterija iz tla koja proizvodi i većinu naših antibiotika.
08:35
Where you used to see dirt,
162
515045
1673
Dosad ste vidjeli zemlju,
08:36
now think of medication.
163
516742
1931
sad mislite na lijekove.
08:40
Perhaps my favorite example comes from colleagues
164
520222
2646
Moj najdraži primjer dolazi od kolega
08:42
who are studying a pond scum microorganism,
165
522892
2896
koji proučavaju mikroorganizam u močvarnom otpadu,
08:45
which is tragically named after the cow dung it was first found in.
166
525812
3619
a koji je tragično nazvan prema kravljem izmetu u kojem je prvotno nađen.
08:50
It's pretty unremarkable and would be unworthy of discussion,
167
530208
3958
Prilično je neupečatljiv i ne bi bio vrijedan spomena,
08:54
except that the researchers found that if you feed it to mice,
168
534190
3522
da istraživači nisu otkrili da ako se time nahrani miševe,
08:57
it vaccinates against PTSD.
169
537736
2051
nastaje cjepivo protiv PTSP-a.
09:01
It vaccinates against fear.
170
541662
1904
To je cjepivo protiv straha.
09:05
Where you used to see pond scum, now think of hope.
171
545238
3222
Dosad ste vidjeli samo otpad, sad mislite na nadu.
09:09
There are so many more microbial examples
172
549897
2404
Još je mnogo primjera mikroba
09:12
that I don't have time to talk about today.
173
552325
2144
o kojima danas nemam vremena govoriti.
09:14
I gave you examples of solutions that came from just three species,
174
554942
5384
Dala sam vam primjere rješenja koja su došla od samo tri vrste,
09:20
but imagine what those other 100,000 species in your dust bunnies
175
560350
4346
no, zamislite što bi tih ostalih 100.000 vrsta u vašoj prašini
09:24
might be able to do.
176
564720
1273
moglo učiniti.
09:26
In the future, they might be able to make you sexier
177
566571
3328
U budućnosti bi vas mogli učiniti privlačnijima,
09:30
or smarter
178
570578
1307
ili pametnijima,
09:32
or perhaps live longer.
179
572855
1877
ili dugovječnijima.
09:36
So I want you to look at your finger again.
180
576303
2152
Stoga, želim da ponovno pogledate svoj prst.
09:39
Think about all those microscopic creatures
181
579005
2286
Pomislite na sva ta mikroskopska stvorenja
09:41
that are unknown.
182
581315
1447
koja su nepoznata.
09:42
Think about in the future what they might be able to do
183
582786
3005
Pomislite što bi oni mogli učiniti u budućnosti,
09:45
or make
184
585815
1173
ili stvoriti,
09:47
or whose life they might be able to save.
185
587528
2146
ili čiji život bi mogli spasiti.
09:50
How does your finger feel right now?
186
590891
1803
Kako sad osjećate svoj prst?
09:53
A little bit powerful?
187
593322
1505
Moćan je?
09:56
That's because you're feeling the future.
188
596384
2027
To je zato što osjećate budućnost.
09:59
Thank you.
189
599030
1162
Hvala.
