A few years ago,

Prije nekoliko godina,
00:14
with my colleague, Emmanuelle Charpentier,
1
14487
2770
kolegica, Emmanuelle Charpentier,
00:17
I invented a new technology for editing genomes.
2
17281
3258
i ja, izumile smo novu metodu za uređivanje genoma.
00:21
It's called CRISPR-Cas9.
3
21093
2114
Zove se CRISPR-Cas9.
00:23
The CRISPR technology allows scientists to make changes
4
23870
3576
CRISPR metoda omogućuje znanstvenicima da mijenjaju
00:27
to the DNA in cells
5
27470
1855
DNK u stanicama
00:29
that could allow us to cure genetic disease.
6
29349
2906
što bi moglo pomoći u liječenju genetskih bolesti.
00:33
You might be interested to know
7

Možda će vas zanimati da smo
00:34
that the CRISPR technology came about through a basic research project
8
34712
3784
do CRISPR metode došli preko osnovnog istraživanja
00:38
that was aimed at discovering how bacteria fight viral infections.
9
38520
3943
koji je bio usmjeren na otkrivanje načina otpornosti bakterija na virusne infekcije.
00:43
Bacteria have to deal with viruses in their environment,
10
43340
2872
Bakterije se bore s virusima u njihovom okolišu
00:46
and we can think about a viral infection like a ticking time bomb --
11
46236
3664
i virusnu infekciju možemo zamisliti kao tempiranu bombu -
00:49
a bacterium has only a few minutes to defuse the bomb
12
49924
3358
bakterija ima samo nekoliko minuta detonirati bombu
00:53
before it gets destroyed.
13
53306
1610
prije nego što eksplodira.
00:55
So, many bacteria have in their cells an adaptive immune system called CRISPR,
14
55284
5390
Mnoge bakterije u svojim stanicama imaju adaptivni imunosustav koji se zove CRISPR,
01:00
that allows them to detect viral DNA and destroy it.
15
60698
3646
koji im omogućava da otkriju virusni DNK i unište ga.
01:05
Part of the CRISPR system is a protein called Cas9,
16
65148
3968
Dio CRISPR sustava je protein koji se zove Cas9,
01:09
that's able to seek out, cut and eventually degrade viral DNA
17
69140
5949
a koji može pretražiti, izrezivati i na kraju i uništiti virusni DNK
01:15
in a specific way.
18
75113
1262
na specifičan način.
01:17
And it was through our research
19
77054
1502
Kroz naše istraživanje
01:18
to understand the activity of this protein, Cas9,
20
78580
3657
pokušali smo razumjeti aktivnosti ovog proteina, Cas9,
01:22
that we realized that we could harness its function
21
82261
2831
da bi shvatili kako možemo iskoristiti njegovu funkciju
01:25
as a genetic engineering technology --
22
85116
3406
za genetski inženjering -
01:28
a way for scientists to delete or insert specific bits of DNA into cells
23
88546
6951
način kojim znanstvenici brišu ili umeću specifične dijelove DNK u stanice
01:35
with incredible precision --
24
95521
2031
s nevjerojatnom preciznošću -
01:37
that would offer opportunities
25
97576
1667
što bi stvorilo mogućnost
01:39
to do things that really haven't been possible in the past.
26
99267
3072
da radimo stvari koje su prije bile nemoguće.
01:43
The CRISPR technology has already been used
27
103184
2062
CRISPR metoda već se počela koristiti
01:45
to change the DNA in the cells of mice and monkeys,
28
105270
5084
za izmjenu DNK u stanicama miševa i majmuna,
01:50
other organisms as well.
29
110378
1625
kao i drugih organizama.
01:52
Chinese scientists showed recently
30
112527
1755
Kineski su znanstvenici nedavno otkrili
01:54
that they could even use the CRISPR technology
31
114306
2159
da bi mogli koristiti CRISPR metodu
01:56
to change genes in human embryos.
32
116489
2629
za izmjenu gena u ljudskim embrijima.
01:59
And scientists in Philadelphia showed they could use CRISPR
33
119142
3143
Znanstvenici iz Philadelphije koristili su CRISPR
02:02
to remove the DNA of an integrated HIV virus
34
122309
4843
za uklanjanje DNK integriranog virusa HIV-a
02:07
from infected human cells.
35
127176
2195
iz inficirane ljudske stanice.
02:10
The opportunity to do this kind of genome editing
36
130217
3131
Mogućnost ovakve vrste uređivanja gena
02:13
also raises various ethical issues that we have to consider,
37
133372
3283
postavlja različita etička pitanja koja trebamo razmotriti
02:16
because this technology can be employed not only in adult cells,
38
136679
3968
zato što se ova metoda može koristiti ne samo na odraslim stanicama,
02:20
but also in the embryos of organisms,
39
140671
2603
nego i na embrijskim stanicama,
02:23
including our own species.
40
143298
3000
uključujući i našu vrstu.
02:26
And so, together with my colleagues,
41
146767
1998
Tako sam, zajedno sa svojim kolegama,
02:28
I've called for a global conversation about the technology that I co-invented,
42
148789
4488
pokrenula globalnu raspravu o ovoj metodi koju smo izumile,
02:33
so that we can consider all of the ethical and societal implications
43
153301
4540
kako bi razmotrili sve etičke i društvene implikacije
02:37
of a technology like this.
44
157865
1724
ovakve metode.
02:40
What I want to do now is tell you what the CRISPR technology is,
45
160056
4939
Ono što želim učiniti je opisati vam CRISPR,
02:45
what it can do,
46
165019
1454
što može činiti,
02:46
where we are today
47
166497
1245
gdje smo danas,
02:47
and why I think we need to take a prudent path forward
48
167766
3022
i zašto mislim da trebamo razborito napredovati
02:50
in the way that we employ this technology.
49
170812
2353
u načinu korištenja ove metode.
02:55
When viruses infect a cell, they inject their DNA.
50
175085
3746
Kada virusi zaraze stanicu ubace svoj DNK.
02:59
And in a bacterium,
51
179363
1476
U bakteriji
03:00
the CRISPR system allows that DNA to be plucked out of the virus,
52
180863
4865
CRISPR sustav omogućava da se DNK izvadi iz virusne stanice,
03:05
and inserted in little bits into the chromosome --
53
185752
3845
i umetne u malim dijelovima u kromosom -
03:09
the DNA of the bacterium.
54
189621
1950
DNK bakterijske stanice.
03:11
And these integrated bits of viral DNA get inserted at a site called CRISPR.
55
191937
5350
Ovi se integrirani dijelovi virusnog DNK umeću u dio koji se zove CRISPR.
03:18
CRISPR stands for clustered regularly interspaced short palindromic repeats.
56
198032
5995
CRISPR je naziv za sljedove između kojih su kratke ponavljajuće palindromske sekvence.
03:24
(Laughter)
57
204051
1001
(Smijeh)
03:25
A big mouthful -- you can see why we use the acronym CRISPR.
58
205076
3373
Mnogo riječi – vidite zašto koristimo akronim CRISPR.
03:28
It's a mechanism that allows cells to record, over time,
59
208890
3988
To je mehanizam kojim stanice mogu tijekom vremena bilježiti
03:32
the viruses they have been exposed to.
60
212902
2682
viruse kojima su bile izložene.
03:35
And importantly, those bits of DNA are passed on to the cells' progeny,
61
215608
4683
A što je najvažnije, dijelovi DNK prenose se na stanice potomke
03:40
so cells are protected from viruses not only in one generation,
62
220315
4533
te su tako zaštićene od virusa ne samo u jednoj generaciji,
03:44
but over many generations of cells.
63
224872
2349
već i u sljedećim generacijama stanica.
03:47
This allows the cells to keep a record of infection,
64
227245
4285
To je način kojim stanice mogu zapamtiti neku infekciju,
03:51
and as my colleague, Blake Wiedenheft, likes to say,
65
231554
2939
i kao što moj kolega, Blake Wiedenheft, voli reći,
03:54
the CRISPR locus is effectively a genetic vaccination card in cells.
66
234517
4956
CRISPR je efektivan način za genetsko cijepljenje stanica.
04:00
Once those bits of DNA have been inserted into the bacterial chromosome,
67
240572
4498
Jednom kada su dijelovi DNK umetnuti u bakterijski kromosom,
04:05
the cell then makes a little copy of a molecule called RNA,
68
245094
4199
stanica može napraviti kopiju molekule koja se zove RNK,
04:09
which is orange in this picture,
69
249317
2015
narančasta je na ovoj slici,
04:11
that is an exact replicate of the viral DNA.
70
251356
4717
i točna je kopija virusnog DNK.
04:16
RNA is a chemical cousin of DNA,
71
256502
2336
RNK je kemijski rođak DNK,
04:18
and it allows interaction with DNA molecules
72
258862
3953
i omogućava interakciju između molekula DNK
04:22
that have a matching sequence.
73
262839
1999
koje imaju odgovarajuće sekvence.
04:25
So those little bits of RNA from the CRISPR locus
74
265258
3909
Ti mali dijelovi RNK na CRISPR sekvenci
04:29
associate -- they bind -- to protein called Cas9,
75
269191
3789
pridružuju se -- vežu na -- protein koji se zove Cas9,
04:33
which is white in the picture,
76
273004
1935
ovo bijelo na slici,
04:34
and form a complex that functions like a sentinel in the cell.
77
274963
4219
i formiraju kompleks koji funkcionira kao stražar u stanici.
04:39
It searches through all of the DNA in the cell,
78
279206
3414
Pretražuje redom DNK u stanici
04:42
to find sites that match the sequences in the bound RNAs.
79
282644
4252
kako bi pronašao odgovarajuće sekvence na vezanim RNK.
04:46
And when those sites are found --
80
286920
1635
Kada pronađe te sekvence -
04:48
as you can see here, the blue molecule is DNA --
81
288579
3470
kao što možete vidjeti, DNK je plava molekula -
04:52
this complex associates with that DNA
82
292073
2849
ovaj se kompleks veže za DNK
04:54
and allows the Cas9 cleaver to cut up the viral DNA.
83
294946
5302
i omogućava proteinu Cas9 da izreže virusni DNK.
05:00
It makes a very precise break.
84
300272
2356
To čini vrlo precizno.
05:04
So we can think of the Cas9 RNA sentinel complex
85
304096
4400
Možemo zamisliti Cas9 RNK stražarski kompleks
05:08
like a pair of scissors that can cut DNA --
86
308520
3181
kao par škara koji reže DNK -
05:11
it makes a double-stranded break in the DNA helix.
87
311725
3236
i čini dvolančani rez na uzvojnici DNK.
05:14
And importantly, this complex is programmable,
88
314985
3982
Što je najvažnije, ovaj je kompleks programabilan
05:18
so it can be programmed to recognize particular DNA sequences,
89
318991
5200
i može biti programiran da prepozna određene sekvence DNK,
05:24
and make a break in the DNA at that site.
90
324215
3027
i napravi rez na tom mjestu na DNK.
05:27
As I'm going to tell you now,
91
327928
1580
Kao što ću vam sada reći,
05:29
we recognized that that activity could be harnessed for genome engineering,
92
329532
4776
prepoznali smo da se ta funkcija može iskoristiti za genetički inženjering,
05:34
to allow cells to make a very precise change to the DNA
93
334332
4227
što omogućuje stanicama preciznu izmjenu vlastitog DNK
05:38
at the site where this break was introduced.
94
338583
2472
na mjestu gdje je potrebna promjena.
05:41
That's sort of analogous
95
341558
1215
To je djelomično slično
05:42
to the way that we use a word-processing program
96
342797
2708
načinu na koji koristimo program za obradu teksta
05:45
to fix a typo in a document.
97
345529
2280
kako bi ispravili tipografsku grešku.
05:49
The reason we envisioned using the CRISPR system for genome engineering
98
349541
4818
Ono što nas je navelo na korištenje CRISPR sustava za genetički inženjering
05:54
is because cells have the ability to detect broken DNA
99
354383
3619
je to što stanice imaju sposobnost otkriti oštećeni DNK
05:58
and repair it.
100
358026
1192
i popraviti ga.
05:59
So when a plant or an animal cell detects a double-stranded break in its DNA,
101
359780
4931
Kad biljna ili životinjska stanica otkrije grešku na dvostrukom lancu DNK,
06:04
it can fix that break,
102
364735
1597
može to ispraviti
06:06
either by pasting together the ends of the broken DNA
103
366356
3527
tako da zalijepi krajeve slomljenog DNK
06:09
with a little, tiny change in the sequence of that position,
104
369907
4110
s vrlo malom promjenom u sekvenci na tom mjestu
06:14
or it can repair the break by integrating a new piece of DNA at the site of the cut.
105
374041
6283
ili može ispraviti oštećenje umetanjem novih sekvenci DNK na mjestu loma.
06:21
So if we have a way to introduce double-stranded breaks into DNA
106
381054
4973
Ako imamo način kojim možemo inducirati dvolančane lomove na DNK
06:26
at precise places,
107
386051
1580
na određenom mjestu,
06:27
we can trigger cells to repair those breaks,
108
387655
2809
možemo potaknuti stanicu na popravak tih lomova
06:30
by either the disruption or incorporation of new genetic information.
109
390488
5023
poremećajem ili ugradnjom nove genetske informacije.
06:35
So if we were able to program the CRISPR technology
110
395936
3242
Ako možemo pomoću CRISPR metode
06:39
to make a break in DNA
111
399202
2323
inducirati oštećenje DNK
06:41
at the position at or near a mutation causing cystic fibrosis, for example,
112
401549
6269
na mjestu ili blizu mjesta mutacijekoja uzrokuje, primjerice, cističnu fibrozu,
06:47
we could trigger cells to repair that mutation.
113
407842
3505
mogli bismo potaknuti stanicu na ispravak mutacije.
06:52
Genome engineering is actually not new, it's been in development since the 1970s.
114
412464
5103
Genetički inženjering nije nova stvar, u razvoju je od 1970-ih.
06:57
We've had technologies for sequencing DNA,
115
417591
2751
Postoje metode za sekvenciranje,
07:00
for copying DNA,
116
420366
1595
kopiranje,
07:01
and even for manipulating DNA.
117
421985
2380
čak i za manipuliranje DNK.
07:04
And these technologies were very promising,
118
424969
3136
Ove su metode bile vrlo obećavajuće,
07:08
but the problem was that they were either inefficient,
119
428129
4406
ali problem je što su ili nedovoljno učinkovite
07:12
or they were difficult enough to use
120
432559
2333
ili problematične za upotrebu
07:14
that most scientists had not adopted them for use in their own laboratories,
121
434916
4802
pa ih mnogi znanstvenici nisu usvojili za upotrebu u svojim laboratorijima,
07:19
or certainly for many clinical applications.
122
439742
4165
a zasigurno ni za mnoge kliničke primjene.
07:24
So, the opportunity to take a technology like CRISPR and utilize it has appeal,
123
444722
7000
Mogućnost da se metoda kao što je CRISPR upotrijebi je privlačna
07:32
because of its relative simplicity.
124
452101
3001
zbog svoje relativne jednostavnosti.
07:35
We can think of older genome engineering technologies
125
455126
3769
Možemo starije metode genetskog inženjeringa
07:38
as similar to having to rewire your computer
126
458919
3659
usporediti s prespajanjem vašeg računala
07:42
each time you want to run a new piece of software,
127
462602
3770
svaki put kada želite pokrenuti novi softver,
07:46
whereas the CRISPR technology is like software for the genome,
128
466396
3764
a CRISPR je metoda kao stoftver za genom,
07:50
we can program it easily, using these little bits of RNA.
129
470184
3486
možemo ju lako isprogramirati, korištenjem dijelića RNK.
07:54
So once a double-stranded break is made in DNA,
130
474658
3093
Jednom kada je dvostruki lom napravljen na DNK,
07:57
we can induce repair,
131
477775
2087
možemo potaknuti popravak
07:59
and thereby potentially achieve astounding things,
132
479886
3446
i time postići potencijalno zapanjujuće stvari,
08:03
like being able to correct mutations that cause sickle cell anemia
133
483356
4159
kao što su popravljanje mutacija koje uzrokuje anemiju srpastih stanica
08:07
or cause Huntington's Disease.
134
487539
2351
ili Huntigtonovu bolest.
08:09
I actually think that the first applications of the CRISPR technology
135
489914
3461
Zapravo mislim da će se prve primjene CRISPR metode
08:13
are going to happen in the blood,
136
493399
2269
dogoditi u krvožilnom sustavu,
08:15
where it's relatively easier to deliver this tool into cells,
137
495692
4753
gdje je relativno lakše koristiti ovu metodu na stanicama
08:20
compared to solid tissues.
138
500469
2121
u odnosu na čvrsta tkiva.
08:23
Right now, a lot of the work that's going on
139
503905
2404
Puno se posla koji se sada odvija
08:26
applies to animal models of human disease, such as mice.
140
506333
3969
odnosi na životinjske modele ljudskih bolesti, kao što su miševi.
08:30
The technology is being used to make very precise changes
141
510326
3269
Metoda se koristi kako bi napravili vrlo precizne promjene
08:33
that allow us to study the way that these changes in the cell's DNA
142
513619
5171
koje omogućavaju proučavanje načina na koji ove promjene u staničnom DNK
08:38
affect either a tissue or, in this case, an entire organism.
143
518814
4320
utječu na tkiva ili, u ovom slučaju, na cijeli organizam.
08:43
Now in this example,
144
523515
1207
U ovom smo primjeru,
08:44
the CRISPR technology was used to disrupt a gene
145
524746
3793
CRISPR metodom poremetili gene
08:48
by making a tiny change in the DNA
146
528563
2767
učinivši malu promjenu u DNK
08:51
in a gene that is responsible for the black coat color of these mice.
147
531354
4444
u genu koji je odgovoran za crnu boju krzna ovog miša.
08:56
Imagine that these white mice differ from their pigmented litter-mates
148
536219
5018
Zamislite da se ovaj bijeli miš razlikuje od svojih obojanih sustanara
09:01
by just a tiny change at one gene in the entire genome,
149
541261
4667
samo po maloj genskoj promjeni u cijelom genomu,
09:05
and they're otherwise completely normal.
150
545952
1990
a po svemu je ostalome sasvim normalan.
09:07
And when we sequence the DNA from these animals,
151
547966
2891
Kada sekvencioniramo DNK ovih životinja,
09:10
we find that the change in the DNA
152
550881
2626
uočavamo da se promjena u DNK
09:13
has occurred at exactly the place where we induced it,
153
553531
3142
nalazi na upravo onom mjestu na kojem smo ju inducirali
09:16
using the CRISPR technology.
154
556697
1762
koristeći CRISPR metodu.
09:19
Additional experiments are going on in other animals
155
559662
2724
Dodatni se pokusi vrše na drugim životinjama
09:22
that are useful for creating models for human disease,
156
562410
4095
koje su korisne za stvaranje modela za ljudske bolesti,
09:26
such as monkeys.
157
566529
1603
kao naprimjer majmunima.
09:28
And here we find that we can use these systems
158
568156
3226
Zaključili smo da ovakav sustav možemo koristiti
09:31
to test the application of this technology in particular tissues,
159
571406
3802
za testiranje uporabe ove metode u određenim tkivima,
09:35
for example, figuring out how to deliver the CRISPR tool into cells.
160
575232
5073
primjerice, kako dostaviti CRISPR u stanice.
09:40
We also want to understand better
161
580329
2148
Također želimo bolje razumjeti
09:42
how to control the way that DNA is repaired after it's cut,
162
582501
3627
kako kontrolirati način na koji je DNK popravljen nakon reza,
09:46
and also to figure out how to control and limit any kind of off-target,
163
586152
5681
ali i shvatiti kako ćemo kontrolirati i ograničiti bilo koji neciljan
09:51
or unintended effects of using the technology.
164
591857
3237
ili nenamjeran učinak korištenja ove metode.
09:56
I think that we will see clinical application of this technology,
165
596356
6150
Mislim da ćemo vidjeti ovu metodu u kliničkoj uporabi,
10:02
certainly in adults,
166
602530
1512
zasigurno kod odraslih,
10:04
within the next 10 years.
167
604066
1603
u sljedećih 10 godina.
10:05
I think that it's likely that we will see clinical trials
168
605693
3134
Mislim da je moguće da će postojati klinička ispitivanja,
10:08
and possibly even approved therapies within that time,
169
608851
3429
a vjerojatno i odobrene terapije unutar tog vremena,
10:12
which is a very exciting thing to think about.
170
612304
2713
što je vrlo uzbudljiva stvar, kad razmislite.
10:15
And because of the excitement around this technology,
171
615041
2501
Zbog uzbuđenja oko ove metode,
10:17
there's a lot of interest in start-up companies
172
617566
3293
mnogo je zanimanja u novim tvrtkama
10:20
that have been founded to commercialize the CRISPR technology,
173
620883
4762
koje su osnovane kako bi komercijalizirale CRISPR metodu,
10:25
and lots of venture capitalists
174
625669
1489
ali i puno smjelih kapitalista
10:27
that have been investing in these companies.
175
627182
2572
koji ulažu u ove tvrtke.
10:31
But we have to also consider
176
631242
1573
Moramo još razumjeti da se
10:32
that the CRISPR technology can be used for things like enhancement.
177
632839
3622
CRISPR metoda može koristiti za stvari kao što je poboljšanje.
10:36
Imagine that we could try to engineer humans
178
636485
3044
Zamislite da probamo stvoriti ljude
10:39
that have enhanced properties, such as stronger bones,
179
639553
4435
koji bi imali poboljšane značajke, kao što su jače kosti,
10:44
or less susceptibility to cardiovascular disease
180
644012
4071
ili manju sklonost kardiovaskularnim bolestima
10:48
or even to have properties
181
648107
1511
ili imaju značajke
10:49
that we would consider maybe to be desirable,
182
649642
2399
koje bismo možda smatrali poželjnijima,
10:52
like a different eye color or to be taller, things like that.
183
652065
4441
kao što je druga boja očiju ili visina, takve stvari.
10:57
"Designer humans," if you will.
184
657942
1846
Nazovimo to dizajniranim ljudima.
11:00
Right now, the genetic information
185
660780
2390
Upravo sada, genetske informacije
11:03
to understand what types of genes would give rise to these traits
186
663194
4493
za razumijevanje tipa gena koji bi doveli do takvih osobina
11:07
is mostly not known.
187
667711
1733
uglavnom su nepoznate.
11:09
But it's important to know
188
669468
1246
Ali važno je znati
11:10
that the CRISPR technology gives us a tool to make such changes,
189
670738
4285
da je CRISPR metoda alat koji će omogućiti takvu vrstu promjene,
11:15
once that knowledge becomes available.
190
675047
2507
jednom kada znanje postane dostupno.
11:18
This raises a number of ethical questions that we have to carefully consider,
191
678651
4111
Ovo postavlja brojna etička pitanja koja je potrebno pomno razmotriti,
11:22
and this is why I and my colleagues have called for a global pause
192
682786
4215
i to je razlog zašto smo kolege i ja pozvali na globalnu stanku
11:27
in any clinical application of the CRISPR technology in human embryos,
193
687025
4746
u kliničkoj primjeni CRISPR metode na ljudskim embrijima,
11:31
to give us time
194
691795
1151
kako bismo uspjeli
11:32
to really consider all of the various implications of doing so.
195
692970
4377
razmotriti različite implikacije za to.
11:37
And actually, there is an important precedent for such a pause
196
697743
3843
Zapravo, postoji važan presedan za takvu stanku
11:41
from the 1970s,
197
701610
1319
iz 1970-ih,
11:42
when scientists got together
198
702953
1864
kada su se znanstvenici sastali
11:44
to call for a moratorium on the use of molecular cloning,
199
704841
3830
i zatražili moratorij na korištenje molekularnog kloniranja,
11:48
until the safety of that technology could be tested carefully and validated.
200
708695
5955
dok se sigurnost metode pažljivo ne testira i opravda.
11:55
So, genome-engineered humans are not with us yet,
201
715506
5140
Genski uređeni ljudi još ne postoje,
12:00
but this is no longer science fiction.
202
720670
2647
no to više nije znanstvena fantastika.
12:04
Genome-engineered animals and plants are happening right now.
203
724179
4365
Genski uređene životinje i biljke sada su stvarnost.
12:09
And this puts in front of all of us a huge responsibility,
204
729069
4053
Ovo nam svima nameće veliku odgovornost
12:13
to consider carefully both the unintended consequences
205
733146
4577
da pažljivo razmotrimo neželjene posljedice
12:17
as well as the intended impacts of a scientific breakthrough.
206
737747
4046
kao i željene učinke ovog znanstvenog otkrića.
12:22
Thank you.
207
742190
1152
Hvala.
12:23
(Applause)

(Pljesak završava)
12:33
Bruno Giussani: Jennifer, this is a technology with huge consequences,
210
753535
3894
Bruno Giussani: Jennifer, ovo je metoda koja nosi velike posljedice,
12:37
as you pointed out.
211
757453
1151
kao što ste istaknuli.
12:38
Your attitude about asking for a pause or a moratorium or a quarantine
212
758628
5172
Vaš stav i molba za stankom ili moratorijem ili karantenom
12:43
is incredibly responsible.
213
763824
2020
izuzetno je odgovoran.
12:46
There are, of course, the therapeutic results of this,
214
766733
2548
Postoje, naravno, terapijski rezultati ovoga,
12:49
but then there are the un-therapeutic ones
215
769305
2150
ali postoje i oni neterapijski,
12:51
and they seem to be the ones gaining traction,
216
771479
2180
a oni, čini se, dobivaju najviše pažnje,
12:53
particularly in the media.
217
773683
1246
posebice u medijima.
12:54
This is one of the latest issues of The Economist -- "Editing humanity."
218
774953
4166
Ovo je jedan od zadnjih brojeva The Economista – „Uređivanje čovječanstva“
12:59
It's all about genetic enhancement, it's not about therapeutics.
219
779143
3819
Sve je o genetskom poboljšanju, a ne o liječenju.
13:03
What kind of reactions did you get back in March
220
783541
2282
Kakve ste reakcije dobili u ožujku
13:05
from your colleagues in the science world,
221
785847
2017
od svojih kolega u znanstvenom svijetu,
13:07
when you asked or suggested
222
787888
1358
kada ste pitali, predložili
13:09
that we should actually pause this for a moment and think about it?
223
789270
3316
da bi trebali napraviti stanku na trenutak i razmisliti o svemu?
13:13
Jennifer Doudna: My colleagues were actually, I think, delighted
224
793054
3001
Jennifer Doudna: Moje su kolege, zapravo bili oduševljeni
13:16
to have the opportunity to discuss this openly.
225
796079
2245
što imaju priliku otvoreno razgovarati.
13:18
It's interesting that as I talk to people,
226
798348
2346
Zanimljivo je da u razgovoru s ljudima,
13:20
my scientific colleagues as well as others,
227
800718
2468
kolegama znanstvenicima, ali i drugima,
13:23
there's a wide variety of viewpoints about this.
228
803210
2310
vidim da postoje razni pogledi na sve ovo.
13:25
So clearly it's a topic that needs careful consideration and discussion.
229
805544
3674
Jasno je da su za ovu temu potrebni pažljivo razmatranje i rasprava.
13:29
BG: There's a big meeting happening in December
230
809242
2215
BG: Važan se sastanak održava u prosincu ove godine
13:31
that you and your colleagues are calling,
231
811481
1976
koji ste sazvali vi i vaši kolege,
13:33
together with the National Academy of Sciences and others,
232
813481
2767
zajedno s Nacionalnom akademijom znanosti i drugima,
13:36
what do you hope will come out of the meeting, practically?
233
816272
3292
što mislite, što će proizaći iz njega?
13:39
JD: Well, I hope that we can air the views
234
819588
2366
JD: Nadam se da možemo obznaniti poglede
13:41
of many different individuals and stakeholders
235
821978
3600
različitih individualaca i dioničara
13:45
who want to think about how to use this technology responsibly.
236
825602
4292
koji žele razmišljati o tome kako ovu metodu odgovorno upotrebljavati.
13:49
It may not be possible to come up with a consensus point of view,
237
829918
3102
Možda neće biti moguće doći do zajedničkog stajališta,
13:53
but I think we should at least understand
238
833044
1993
ali mislim da, kako napredujemo,
13:55
what all the issues are as we go forward.
239
835061
1972
trebamo razumjeti svu materiju.
13:57
BG: Now, colleagues of yours,
240
837057
1406
BG: Neke vaše kolege,
13:58
like George Church, for example, at Harvard,
241
838487
2079
kao što je George Church s Harvada, primjerice,
14:00
they say, "Yeah, ethical issues basically are just a question of safety.
242
840590
3436
kažu, „Etička su pitanja samo pitanja sigurnosti.
14:04
We test and test and test again, in animals and in labs,
243
844050
2654
Mi neprestano testiramo na životinjama i u laboratoriju,
14:06
and then once we feel it's safe enough, we move on to humans."
244
846728
3916
i kada pomislimo da je dovoljno sigurno, prijeći ćemo na ljude.“
14:10
So that's kind of the other school of thought,
245
850668
2581
Ovo je drugačiji način razmišljanja,
14:13
that we should actually use this opportunity and really go for it.
246
853273
3148
da bi trebali ovu priliku u potpunosti iskoristiti.
14:16
Is there a possible split happening in the science community about this?
247
856445
3778
Je li moguće u znanstvenoj zajednici imati podijeljena mišljenja o ovome?
14:20
I mean, are we going to see some people holding back
248
860247
2460
Hoćemo li vidjeti neke ljude kako se suzdržavaju
14:22
because they have ethical concerns,
249
862731
1794
jer imaju etičke brige,
14:24
and some others just going forward
250
864549
1687
a druge kako grabe priliku
14:26
because some countries under-regulate or don't regulate at all?
251
866260
3296
jer neke zemlje slabo ili uopće ne reguliraju etička pitanja?
14:29
JD: Well, I think with any new technology, especially something like this,
252
869580
3845
JD: Mislim da sa svakom novom metodom, a posebno nekom kao što je ova,
14:33
there are going to be a variety of viewpoints,
253
873449
2785
uvijek postoje različita stajališta,
14:36
and I think that's perfectly understandable.
254
876258
3341
i mislim da je to sasvim razumljivo.
14:39
I think that in the end,
255
879623
1512
Mislim da će na kraju
14:41
this technology will be used for human genome engineering,
256
881159
4951
ova metoda biti korištena za genomski inženjering ljudi,
14:46
but I think to do that without careful consideration and discussion
257
886134
4317
ali raditi to bez pažljivog razmatranja i rasprave
14:50
of the risks and potential complications
258
890475
2937
o rizicima i mogućim komplikacijama
14:53
would not be responsible.
259
893436
1539
ne bi bilo odgovorno.
14:54
BG: There are a lot of technologies and other fields of science
260
894999
2979
BG: Postoje mnoge metode i druga znanstvena polja
14:58
that are developing exponentially, pretty much like yours.
261
898002
2771
koja se eksponencijalno razvijaju, slično kao i vaše.
15:00
I'm thinking about artificial intelligence, autonomous robots and so on.
262
900797
4033
Govorim o umjetnoj inteligenciji, samoupravljajućim robotima i tako dalje.
15:05
No one seems --
263
905199
1167
Čini se da ništa -
15:06
aside from autonomous warfare robots --
264
906390
2508
osim ratnih samoupravljajućih robota --
15:08
nobody seems to have launched a similar discussion in those fields,
265
908922
4705
nije pokrenulo sličnu raspravu na tim poljima,
15:13
in calling for a moratorium.
266
913651
1410
i pozvao na moratorij.
15:15
Do you think that your discussion may serve as a blueprint for other fields?
267
915085
4071
Mislite li da će vaša rasprava možda poslužiti kao predložak za ostala polja?
15:19
JD: Well, I think it's hard for scientists to get out of the laboratory.
268
919180
3519
JD: Mislim da je znanstvenicima teško napustiti laboratorij.
15:22
Speaking for myself,
269
922723
1153
Govoreći o sebi,
15:23
it's a little bit uncomfortable to do that.
270
923900
2616
malo je nelagodno to učiniti.
15:26
But I do think that being involved in the genesis of this
271
926540
3914
Ali mislim da uključenost u nastanak ovoga
15:30
really puts me and my colleagues in a position of responsibility.
272
930478
3856
mene i moje kolege stavlja na odgovornu poziciju.
15:34
And I would say that I certainly hope that other technologies
273
934358
3430
Mogu reći da se iskreno nadam da će ostale metode
15:37
will be considered in the same way,
274
937812
2646
biti razmotrene na isti način,
15:40
just as we would want to consider something that could have implications
275
940482
3398
kao što bismo mi htjeli razmotriti nešto što bi moglo imati implikacije
15:43
in other fields besides biology.
276
943904
1927
u drugim poljima, a ne samo u biologiji.
15:45
BG: Jennifer, thanks for coming to TED.
277
945855
1952
BG: Jennifer, hvala ti na dolasku na TED.
15:47
JD: Thank you.
