bacteria<00:00:16.480> are<00:00:16.680> the<00:00:16.840> oldest<00:00:17.279> living<00:00:17.600> organisms
bacteria are the oldest living organisms
bacteria are the oldest living organisms
on<00:00:18.279> the<00:00:18.400> earth<00:00:18.720> they've<00:00:18.920> been<00:00:19.080> here<00:00:19.240> for
on the earth they've been here for
on the earth they've been here for
billions<00:00:19.880> of<00:00:20.119> years<00:00:20.800> and<00:00:20.960> what<00:00:21.160> they<00:00:21.279> are<00:00:21.519> are
billions of years and what they are are
billions of years and what they are are
single<00:00:22.400> cell<00:00:22.960> microscopic<00:00:23.720> organisms<00:00:24.720> so
single cell microscopic organisms so
single cell microscopic organisms so
they're<00:00:25.160> one<00:00:25.439> cell<00:00:25.920> and<00:00:26.039> they<00:00:26.160> have<00:00:26.320> the
they're one cell and they have the
they're one cell and they have the
special<00:00:26.960> property<00:00:27.359> that<00:00:27.519> they<00:00:27.640> only<00:00:27.960> have<00:00:28.279> one
special property that they only have one
special property that they only have one
piece<00:00:28.800> of<00:00:29.039> DNA<00:00:29.560> so<00:00:29.679> they<00:00:29.800> have<00:00:30.160> very<00:00:30.359> few<00:00:30.720> genes
piece of DNA so they have very few genes
piece of DNA so they have very few genes
and<00:00:31.560> genetic<00:00:31.960> information<00:00:32.439> to<00:00:32.599> encode<00:00:33.200> all<00:00:33.320> of
and genetic information to encode all of
and genetic information to encode all of
the<00:00:33.640> traits<00:00:34.120> that<00:00:34.280> they<00:00:34.480> carry<00:00:34.800> out<00:00:35.680> and<00:00:35.760> the
the traits that they carry out and the
the traits that they carry out and the
way<00:00:36.079> bacteria<00:00:36.559> make<00:00:36.719> a<00:00:36.879> living<00:00:37.520> is<00:00:37.640> that<00:00:37.840> they
way bacteria make a living is that they
way bacteria make a living is that they
consume<00:00:38.559> nutrients<00:00:39.079> from<00:00:39.239> the<00:00:39.399> environment
consume nutrients from the environment
consume nutrients from the environment
they<00:00:40.320> grow<00:00:40.559> to<00:00:40.760> twice<00:00:41.160> their<00:00:41.440> size<00:00:41.960> they<00:00:42.120> cut
they grow to twice their size they cut
they grow to twice their size they cut
themselves<00:00:42.800> down<00:00:43.000> in<00:00:43.120> the<00:00:43.239> middle<00:00:43.840> and<00:00:44.000> one
themselves down in the middle and one
themselves down in the middle and one
cell<00:00:44.600> becomes<00:00:45.000> two<00:00:45.520> and<00:00:45.680> so<00:00:45.879> on<00:00:46.079> and<00:00:46.199> so<00:00:46.399> on<00:00:46.559> so
cell becomes two and so on and so on so
cell becomes two and so on and so on so
they<00:00:46.840> just<00:00:47.039> grow<00:00:47.320> and<00:00:47.520> divide<00:00:47.920> and<00:00:48.079> grow<00:00:48.320> and
they just grow and divide and grow and
they just grow and divide and grow and
divide<00:00:49.039> so<00:00:49.360> kind<00:00:49.480> of<00:00:49.640> boring<00:00:50.039> life<00:00:50.600> except
divide so kind of boring life except
divide so kind of boring life except
that<00:00:51.000> what<00:00:51.120> I<00:00:51.199> would<00:00:51.320> argue<00:00:51.640> is<00:00:51.800> that<00:00:51.920> you<00:00:52.120> have
that what I would argue is that you have
that what I would argue is that you have
an<00:00:52.559> amazing<00:00:53.079> interaction<00:00:53.680> with<00:00:53.960> these
an amazing interaction with these
an amazing interaction with these
Critters<00:00:55.120> I<00:00:55.199> know<00:00:55.359> you<00:00:55.520> guys<00:00:55.680> think<00:00:55.840> of
Critters I know you guys think of
Critters I know you guys think of
yourself<00:00:56.320> as<00:00:56.559> humans<00:00:57.239> and<00:00:57.359> this<00:00:57.480> is<00:00:57.719> sort<00:00:57.920> of
yourself as humans and this is sort of
yourself as humans and this is sort of
how<00:00:58.199> I<00:00:58.359> think<00:00:58.519> of<00:00:58.680> you<00:00:58.879> and<00:00:58.960> so<00:00:59.199> this<00:00:59.399> man<00:00:59.719> is
how I think of you and so this man is
how I think of you and so this man is
supposed<00:01:00.280> to<00:01:00.440> represent<00:01:00.960> a<00:01:01.120> generic<00:01:01.559> human
supposed to represent a generic human
supposed to represent a generic human
being<00:01:02.239> and<00:01:02.480> all<00:01:02.600> of<00:01:02.719> the<00:01:02.879> circles<00:01:03.280> in<00:01:03.440> that<00:01:03.600> man
being and all of the circles in that man
being and all of the circles in that man
are<00:01:04.080> all<00:01:04.199> of<00:01:04.360> the<00:01:04.559> cells<00:01:05.159> that<00:01:05.320> make<00:01:05.519> up<00:01:05.720> your
are all of the cells that make up your
are all of the cells that make up your
body<00:01:06.520> so<00:01:06.680> there's<00:01:06.840> about<00:01:07.000> a<00:01:07.159> trillion<00:01:07.680> human
body so there's about a trillion human
body so there's about a trillion human
cells<00:01:08.560> that<00:01:08.680> make<00:01:08.920> each<00:01:09.119> one<00:01:09.320> of<00:01:09.479> us<00:01:10.040> who<00:01:10.240> we
cells that make each one of us who we
cells that make each one of us who we
are<00:01:10.680> and<00:01:10.840> able<00:01:11.040> to<00:01:11.159> do<00:01:11.360> all<00:01:11.479> the<00:01:11.640> things<00:01:11.840> that
are and able to do all the things that
are and able to do all the things that
we<00:01:12.159> do<00:01:12.799> but<00:01:12.920> you<00:01:13.040> have<00:01:13.200> 10<00:01:13.439> trillion<00:01:14.040> bacterial
we do but you have 10 trillion bacterial
we do but you have 10 trillion bacterial
cells<00:01:15.080> in<00:01:15.280> you<00:01:15.439> or<00:01:15.640> on<00:01:15.880> you<00:01:16.280> at<00:01:16.479> any<00:01:16.720> moment<00:01:17.040> in
cells in you or on you at any moment in
cells in you or on you at any moment in
your<00:01:17.360> life<00:01:17.600> so<00:01:17.840> 10<00:01:18.119> times<00:01:18.400> more<00:01:18.680> bacterial
your life so 10 times more bacterial
your life so 10 times more bacterial
cells<00:01:19.920> than<00:01:20.159> human<00:01:20.439> cells<00:01:20.880> on<00:01:21.040> a<00:01:21.200> human<00:01:21.520> being
cells than human cells on a human being
cells than human cells on a human being
and<00:01:22.320> so<00:01:22.479> of<00:01:22.600> course<00:01:22.759> it's<00:01:22.960> the<00:01:23.079> DNA<00:01:23.560> that
and so of course it's the DNA that
and so of course it's the DNA that
counts<00:01:24.119> so<00:01:24.280> here's<00:01:24.479> all<00:01:24.640> the<00:01:24.799> ATS<00:01:25.320> G's<00:01:25.600> and<00:01:25.720> C's
counts so here's all the ATS G's and C's
counts so here's all the ATS G's and C's
that<00:01:26.280> make<00:01:26.439> up<00:01:26.600> your<00:01:26.759> genetic<00:01:27.200> code<00:01:27.479> and<00:01:27.640> give
that make up your genetic code and give
that make up your genetic code and give
you<00:01:27.920> all<00:01:28.040> your<00:01:28.240> Charming<00:01:28.759> characteristics<00:01:29.720> so
you all your Charming characteristics so
you all your Charming characteristics so
so<00:01:30.000> you<00:01:30.079> have<00:01:30.240> about<00:01:30.439> 30,000<00:01:31.119> genes<00:01:31.560> well<00:01:31.680> it
so you have about 30,000 genes well it
so you have about 30,000 genes well it
turns<00:01:32.000> out<00:01:32.200> you<00:01:32.360> have<00:01:32.520> a<00:01:32.720> hundred<00:01:33.079> times<00:01:33.320> more
turns out you have a hundred times more
turns out you have a hundred times more
bacterial<00:01:34.200> genes<00:01:34.960> playing<00:01:35.240> a<00:01:35.439> role<00:01:35.840> in<00:01:36.040> you<00:01:36.240> or
bacterial genes playing a role in you or
bacterial genes playing a role in you or
on<00:01:36.680> you<00:01:37.200> all<00:01:37.360> of<00:01:37.520> your<00:01:37.880> life<00:01:38.520> and<00:01:38.680> so<00:01:39.439> at<00:01:39.600> the
on you all of your life and so at the
on you all of your life and so at the

things as well so there's all kinds of
bacteria<00:02:25.480> on<00:02:25.640> the<00:02:25.800> earth<00:02:26.360> that<00:02:26.519> have<00:02:26.720> no

time and if they are they make you
time and if they are they make you
incredibly<00:02:32.480> sick<00:02:33.480> and<00:02:33.560> so<00:02:33.720> the<00:02:33.879> question<00:02:34.160> for
incredibly sick and so the question for
incredibly sick and so the question for
my<00:02:34.680> lab<00:02:34.959> is<00:02:35.120> whether<00:02:35.319> you<00:02:35.400> want<00:02:35.519> to<00:02:35.720> think
my lab is whether you want to think
my lab is whether you want to think
about<00:02:36.120> all<00:02:36.280> the<00:02:36.519> good<00:02:36.720> things<00:02:36.959> that<00:02:37.200> bacteria
about all the good things that bacteria
about all the good things that bacteria
do<00:02:37.959> or<00:02:38.120> all<00:02:38.280> the<00:02:38.519> bad<00:02:38.800> things<00:02:39.040> that<00:02:39.319> bacteria
do or all the bad things that bacteria
do or all the bad things that bacteria
do<00:02:40.319> the<00:02:40.480> question<00:02:40.760> we<00:02:40.959> had<00:02:41.080> is<00:02:41.239> how<00:02:41.360> could<00:02:41.519> they

do anything at all I mean they're
incredibly<00:02:43.879> small<00:02:44.200> you<00:02:44.360> have<00:02:44.480> to<00:02:44.599> have<00:02:44.680> a
incredibly small you have to have a
incredibly small you have to have a
microscope<00:02:45.519> to<00:02:45.680> see<00:02:45.959> one<00:02:46.360> they<00:02:46.480> live<00:02:46.720> this
microscope to see one they live this
microscope to see one they live this
sing<00:02:47.360> sort<00:02:47.519> of<00:02:47.680> boring<00:02:48.080> life<00:02:48.280> where<00:02:48.440> they<00:02:48.680> grow
sing sort of boring life where they grow
sing sort of boring life where they grow
and<00:02:49.200> divide<00:02:49.800> and<00:02:49.920> they've<00:02:50.159> always<00:02:50.400> been<00:02:50.640> to
and divide and they've always been to

considered to be these asocial reclusive
organisms<00:02:54.519> and<00:02:54.599> so<00:02:54.760> it<00:02:54.879> seemed<00:02:55.159> to<00:02:55.360> us<00:02:55.560> that
organisms and so it seemed to us that
organisms and so it seemed to us that
they're<00:02:55.959> just<00:02:56.200> too<00:02:56.560> small<00:02:57.000> to<00:02:57.200> have<00:02:57.360> an<00:02:57.599> impact
they're just too small to have an impact
they're just too small to have an impact
on<00:02:58.200> the<00:02:58.360> environment<00:02:59.080> if<00:02:59.280> they<00:02:59.440> simply<00:03:00.080> act<00:03:00.400> as
on the environment if they simply act as
on the environment if they simply act as
individuals<00:03:01.680> and<00:03:01.760> so<00:03:01.959> we<00:03:02.080> wanted<00:03:02.360> to<00:03:02.560> think<00:03:02.800> if
individuals and so we wanted to think if
individuals and so we wanted to think if
there<00:03:03.120> couldn't<00:03:03.400> be<00:03:03.560> a<00:03:03.799> different<00:03:04.120> way<00:03:04.360> the
there couldn't be a different way the
there couldn't be a different way the

bacteria live and the clue to this came
bacteria live and the clue to this came
from<00:03:07.920> another<00:03:08.200> Marine<00:03:08.680> bacterium<00:03:09.599> and<00:03:09.680> it's<00:03:09.840> a

a<00:03:19.040> harmless<00:03:19.640> beautiful<00:03:20.159> bacterium<00:03:20.720> that
a harmless beautiful bacterium that
a harmless beautiful bacterium that
comes<00:03:21.120> from<00:03:21.319> the<00:03:21.480> ocean<00:03:22.120> named<00:03:22.360> Vio<00:03:22.799> ferai<00:03:23.599> and

this<00:03:24.000> bacterium<00:03:24.599> has<00:03:24.760> the<00:03:24.959> special<00:03:25.400> property
this bacterium has the special property
this bacterium has the special property
that<00:03:25.959> it<00:03:26.120> makes<00:03:26.480> light<00:03:26.840> so<00:03:27.000> it<00:03:27.080> makes
that it makes light so it makes
that it makes light so it makes
bioluminescence<00:03:28.360> like<00:03:28.599> fireflies<00:03:29.280> make
bioluminescence like fireflies make
bioluminescence like fireflies make
light<00:03:30.120> so<00:03:30.239> we're<00:03:30.400> not<00:03:30.599> doing<00:03:30.959> anything<00:03:31.280> to<00:03:31.439> the
light so we're not doing anything to the
light so we're not doing anything to the
cells<00:03:31.959> here<00:03:32.239> we<00:03:32.400> just<00:03:32.560> took<00:03:32.760> the<00:03:32.920> picture<00:03:33.239> by
cells here we just took the picture by
cells here we just took the picture by
turning<00:03:33.680> the<00:03:33.799> lights<00:03:34.080> off<00:03:34.239> in<00:03:34.360> the<00:03:34.519> room<00:03:35.000> and
turning the lights off in the room and
turning the lights off in the room and
this<00:03:35.319> is<00:03:35.480> what<00:03:35.640> we<00:03:35.760> see<00:03:36.680> and<00:03:36.799> what<00:03:36.920> was
this is what we see and what was
this is what we see and what was
actually<00:03:37.480> interesting<00:03:38.000> to<00:03:38.200> us<00:03:38.400> was<00:03:38.599> not<00:03:38.879> that
actually interesting to us was not that
actually interesting to us was not that
the<00:03:39.319> bacteria<00:03:39.799> made<00:03:40.040> light<00:03:40.480> but<00:03:40.720> when<00:03:41.000> the
the bacteria made light but when the
the bacteria made light but when the
bacteria<00:03:41.720> made<00:03:41.959> light<00:03:42.680> what<00:03:42.840> we<00:03:43.000> noticed<00:03:43.439> is
bacteria made light what we noticed is
bacteria made light what we noticed is
when<00:03:43.799> the<00:03:44.000> bacteria<00:03:44.439> were<00:03:44.680> alone<00:03:45.200> so<00:03:45.360> when
when the bacteria were alone so when
when the bacteria were alone so when
they<00:03:45.599> were<00:03:45.799> in<00:03:45.959> dilute<00:03:46.519> suspension<00:03:47.519> they<00:03:47.640> made
they were in dilute suspension they made
they were in dilute suspension they made
no<00:03:48.200> light<00:03:48.920> but<00:03:49.040> when<00:03:49.159> they<00:03:49.280> grew<00:03:49.560> to<00:03:49.720> a<00:03:49.879> certain
no light but when they grew to a certain
no light but when they grew to a certain
cell<00:03:50.439> number<00:03:51.040> all<00:03:51.239> the<00:03:51.439> bacteria<00:03:52.000> turned<00:03:52.319> on
cell number all the bacteria turned on
cell number all the bacteria turned on
light<00:03:53.360> simultaneously<00:03:54.360> and<00:03:54.439> so<00:03:54.640> the<00:03:54.840> question
light simultaneously and so the question
light simultaneously and so the question
that<00:03:55.400> we<00:03:55.640> had<00:03:55.920> is<00:03:56.120> how<00:03:56.280> can<00:03:56.599> bacteria<00:03:57.280> these
that we had is how can bacteria these
that we had is how can bacteria these
primitive<00:03:57.959> organisms<00:03:58.840> tell<00:03:59.079> the<00:03:59.239> difference
primitive organisms tell the difference
primitive organisms tell the difference
from<00:04:00.000> times<00:04:00.200> when<00:04:00.360> they're<00:04:00.560> alone<00:04:01.159> and<00:04:01.360> times
from times when they're alone and times
from times when they're alone and times
when<00:04:01.720> they're<00:04:01.840> in<00:04:01.959> a<00:04:02.120> community<00:04:02.799> and<00:04:02.920> then<00:04:03.159> all
when they're in a community and then all
when they're in a community and then all
do<00:04:03.680> something<00:04:04.920> together<00:04:05.920> and<00:04:06.040> what<00:04:06.200> we
do something together and what we
do something together and what we
figured<00:04:06.680> out<00:04:06.920> is<00:04:07.040> that<00:04:07.200> the<00:04:07.360> way<00:04:07.560> that<00:04:07.760> they<00:04:07.920> do
figured out is that the way that they do
figured out is that the way that they do
that<00:04:08.360> is<00:04:08.480> that<00:04:08.680> they<00:04:08.879> talk<00:04:09.120> to<00:04:09.360> each<00:04:09.519> other<00:04:10.000> and
that is that they talk to each other and
that is that they talk to each other and
they<00:04:10.280> talk<00:04:10.560> with<00:04:10.680> a<00:04:10.879> chemical<00:04:11.360> language<00:04:12.120> so
they talk with a chemical language so
they talk with a chemical language so
this<00:04:12.480> is<00:04:12.680> now<00:04:12.879> supposed<00:04:13.239> to<00:04:13.360> be<00:04:13.519> my<00:04:13.760> bacterial
this is now supposed to be my bacterial
this is now supposed to be my bacterial
cell<00:04:14.959> when<00:04:15.079> it's<00:04:15.280> alone<00:04:15.920> it<00:04:16.040> doesn't<00:04:16.320> make<00:04:16.560> any
cell when it's alone it doesn't make any
cell when it's alone it doesn't make any
light<00:04:17.479> but<00:04:17.639> what<00:04:17.759> it<00:04:17.919> does<00:04:18.239> do<00:04:18.560> is<00:04:18.680> to<00:04:18.919> make<00:04:19.199> and
light but what it does do is to make and
light but what it does do is to make and
secrete<00:04:20.160> small<00:04:20.560> molecules<00:04:21.199> that<00:04:21.320> you<00:04:21.440> can
secrete small molecules that you can
secrete small molecules that you can
think<00:04:21.759> of<00:04:21.959> like<00:04:22.199> hormones<00:04:23.120> and<00:04:23.240> these<00:04:23.360> are<00:04:23.520> the
think of like hormones and these are the
think of like hormones and these are the
red<00:04:23.960> triangles<00:04:24.880> and<00:04:25.000> when<00:04:25.120> the<00:04:25.280> bacteria<00:04:25.800> is
red triangles and when the bacteria is
red triangles and when the bacteria is
alone<00:04:26.639> the<00:04:26.759> molecules<00:04:27.400> just<00:04:27.560> float<00:04:27.960> away<00:04:28.479> and
alone the molecules just float away and
alone the molecules just float away and
so<00:04:28.840> no<00:04:29.080> light<00:04:29.840> but<00:04:30.000> when<00:04:30.199> the<00:04:30.400> bacteria<00:04:30.880> grow
so no light but when the bacteria grow
so no light but when the bacteria grow
and<00:04:31.360> double<00:04:31.800> and<00:04:31.960> they're<00:04:32.199> all<00:04:32.600> participating
and double and they're all participating
and double and they're all participating
in<00:04:33.639> making<00:04:34.080> these<00:04:34.280> molecules<00:04:35.160> the<00:04:35.360> molecule

number and when the molecule hits a
certain<00:04:43.280> amount<00:04:43.840> that<00:04:44.000> tells<00:04:44.320> the<00:04:44.520> bacteria
certain amount that tells the bacteria
certain amount that tells the bacteria
how<00:04:45.120> many<00:04:45.320> neighbors<00:04:45.840> they<00:04:45.960> are<00:04:46.440> they
how many neighbors they are they
how many neighbors they are they
recognize<00:04:47.240> that<00:04:47.400> molecule<00:04:47.919> and<00:04:48.120> all<00:04:48.320> of<00:04:48.440> the
recognize that molecule and all of the
recognize that molecule and all of the
bacteria<00:04:49.400> turn<00:04:49.680> on<00:04:49.960> light<00:04:50.440> in<00:04:50.680> synchrony<00:04:51.560> and
bacteria turn on light in synchrony and
bacteria turn on light in synchrony and
so<00:04:51.880> that's<00:04:52.120> how<00:04:52.320> bioluminescence<00:04:53.280> Works
so that's how bioluminescence Works
so that's how bioluminescence Works

live in there at high cell number that
molecule<00:05:17.880> is<00:05:18.120> there<00:05:18.440> and<00:05:18.639> they're<00:05:18.919> making
molecule is there and they're making
molecule is there and they're making
light<00:05:20.120> and<00:05:20.240> the<00:05:20.400> reason<00:05:20.680> the<00:05:20.800> squid<00:05:21.080> is
light and the reason the squid is
light and the reason the squid is
willing<00:05:21.400> to<00:05:21.520> put<00:05:21.680> up<00:05:21.800> with<00:05:21.919> these<00:05:22.080> Shenanigans
willing to put up with these Shenanigans
willing to put up with these Shenanigans
is<00:05:22.960> because<00:05:23.280> it<00:05:23.360> wants<00:05:23.840> that<00:05:24.039> light<00:05:24.680> and<00:05:24.759> so
is because it wants that light and so
is because it wants that light and so
the<00:05:25.080> way<00:05:25.280> that<00:05:25.440> this<00:05:25.639> symbiosis<00:05:26.360> works<00:05:26.720> is
the way that this symbiosis works is
the way that this symbiosis works is
that<00:05:27.000> this<00:05:27.199> little<00:05:27.479> squid<00:05:27.880> lives<00:05:28.199> just<00:05:28.440> off

that this little squid lives just off
the<00:05:28.800> coast<00:05:29.160> of<00:05:29.720> Hawaii<00:05:30.240> so<00:05:30.440> just<00:05:30.560> in<00:05:30.759> sort<00:05:30.960> of
the coast of Hawaii so just in sort of
the coast of Hawaii so just in sort of
shallow<00:05:31.560> kneee<00:05:32.160> water<00:05:32.720> and<00:05:32.840> the<00:05:32.960> squid<00:05:33.319> is
shallow kneee water and the squid is
shallow kneee water and the squid is
nocturnal<00:05:34.280> so<00:05:34.479> during<00:05:34.759> the<00:05:34.960> day<00:05:35.280> it<00:05:35.440> buries

nocturnal so during the day it buries
itself<00:05:36.199> in<00:05:36.319> the<00:05:36.520> sand<00:05:36.919> and<00:05:37.080> sleeps<00:05:37.919> but<00:05:38.039> then

itself in the sand and sleeps but then
at<00:05:38.360> night<00:05:38.560> it<00:05:38.720> has<00:05:38.880> to<00:05:39.039> come<00:05:39.199> out<00:05:39.360> to<00:05:39.560> hunt<00:05:40.199> and

organ<00:05:54.440> housing<00:05:54.800> the<00:05:55.039> bacteria<00:05:55.960> and<00:05:56.080> then<00:05:56.199> it

sense how much Starlight or Moonlight is
sense how much Starlight or Moonlight is
hitting<00:06:00.639> its<00:06:00.919> back<00:06:01.479> and<00:06:01.600> it<00:06:01.720> opens<00:06:02.000> and<00:06:02.199> closes
hitting its back and it opens and closes
hitting its back and it opens and closes
the<00:06:02.720> shutter<00:06:03.280> so<00:06:03.479> the<00:06:03.600> amount<00:06:03.800> of<00:06:03.919> light
the shutter so the amount of light
the shutter so the amount of light
coming<00:06:04.360> out<00:06:04.479> of<00:06:04.639> the<00:06:04.759> bottom<00:06:05.360> which<00:06:05.479> is<00:06:05.639> made
coming out of the bottom which is made
coming out of the bottom which is made
by<00:06:06.000> the<00:06:06.160> bacterium<00:06:07.160> exactly<00:06:07.639> matches<00:06:08.000> how
by the bacterium exactly matches how
by the bacterium exactly matches how
much<00:06:08.360> light<00:06:08.599> hits<00:06:08.800> the<00:06:08.960> Squid's<00:06:09.400> back<00:06:09.800> so<00:06:10.000> the
much light hits the Squid's back so the
much light hits the Squid's back so the
squid<00:06:10.440> doesn't<00:06:10.680> make<00:06:10.840> a<00:06:11.039> Shadow<00:06:11.840> so<00:06:12.000> it
squid doesn't make a Shadow so it
squid doesn't make a Shadow so it
actually<00:06:12.520> uses<00:06:13.000> the<00:06:13.160> light<00:06:13.400> from<00:06:13.560> the
actually uses the light from the
actually uses the light from the
bacteria<00:06:14.280> to<00:06:14.520> counter<00:06:14.880> illuminate<00:06:15.400> itself<00:06:15.840> in
bacteria to counter illuminate itself in
bacteria to counter illuminate itself in
an<00:06:16.199> anti-predation<00:06:17.199> device<00:06:17.759> and<00:06:17.840> so<00:06:18.039> it<00:06:18.160> so
an anti-predation device and so it so
an anti-predation device and so it so
predators<00:06:18.919> can't<00:06:19.160> see<00:06:19.400> its<00:06:19.599> shadow<00:06:20.039> calculate
predators can't see its shadow calculate
predators can't see its shadow calculate
its<00:06:20.639> trajectory<00:06:21.160> and<00:06:21.319> eat<00:06:21.560> it<00:06:21.960> and<00:06:22.039> so<00:06:22.199> this<00:06:22.319> is
its trajectory and eat it and so this is
its trajectory and eat it and so this is
like<00:06:22.599> the<00:06:22.759> stealth<00:06:23.120> bomber<00:06:23.520> of<00:06:23.720> the
like the stealth bomber of the
like the stealth bomber of the
ocean<00:06:25.440> but<00:06:25.560> then<00:06:25.720> if<00:06:25.800> you<00:06:26.000> think<00:06:26.240> about<00:06:26.440> it
ocean but then if you think about it
ocean but then if you think about it
this<00:06:26.800> squid<00:06:27.199> has<00:06:27.400> this<00:06:27.639> terrible<00:06:28.199> problem
this squid has this terrible problem
this squid has this terrible problem
because<00:06:28.720> it's<00:06:28.919> got<00:06:29.080> this<00:06:29.280> D<00:06:29.720> ing<00:06:30.199> thick
because it's got this D ing thick
because it's got this D ing thick
culture<00:06:30.880> of<00:06:31.120> bacteria<00:06:31.639> and<00:06:31.759> it<00:06:31.919> can't<00:06:32.240> sustain
culture of bacteria and it can't sustain
culture of bacteria and it can't sustain
that<00:06:33.360> and<00:06:33.440> so<00:06:33.639> what<00:06:33.800> happens<00:06:34.120> is<00:06:34.360> every
that and so what happens is every
that and so what happens is every
morning<00:06:35.080> when<00:06:35.199> the<00:06:35.319> sun<00:06:35.560> comes<00:06:35.800> up<00:06:36.000> the<00:06:36.120> Squid
morning when the sun comes up the Squid
morning when the sun comes up the Squid
goes<00:06:36.680> back<00:06:36.800> to<00:06:36.960> sleep<00:06:37.199> it<00:06:37.319> buries<00:06:37.680> itself<00:06:38.000> in
goes back to sleep it buries itself in
goes back to sleep it buries itself in
the<00:06:38.280> sand<00:06:38.880> and<00:06:39.000> it's<00:06:39.160> got<00:06:39.280> a<00:06:39.479> pump<00:06:39.840> that's
the sand and it's got a pump that's
the sand and it's got a pump that's
attached<00:06:40.360> to<00:06:40.479> its<00:06:40.599> circadian<00:06:41.240> rhythm<00:06:41.840> and
attached to its circadian rhythm and
attached to its circadian rhythm and
when<00:06:42.080> the<00:06:42.199> sun<00:06:42.520> comes<00:06:42.759> up<00:06:43.039> it<00:06:43.280> pumps<00:06:43.639> out<00:06:43.919> like
when the sun comes up it pumps out like
when the sun comes up it pumps out like
95%<00:06:45.039> of<00:06:45.160> the<00:06:45.319> bacteria<00:06:46.199> and<00:06:46.319> so<00:06:46.479> now<00:06:46.639> the
95% of the bacteria and so now the
95% of the bacteria and so now the
bacteria<00:06:47.240> are<00:06:47.440> dilute<00:06:48.120> that<00:06:48.280> little<00:06:48.479> hormone
bacteria are dilute that little hormone
bacteria are dilute that little hormone
molecule<00:06:49.319> is<00:06:49.520> gone<00:06:49.759> so<00:06:49.960> they're<00:06:50.080> not<00:06:50.240> making
molecule is gone so they're not making
molecule is gone so they're not making
light<00:06:50.840> but<00:06:50.960> of<00:06:51.080> course<00:06:51.240> the<00:06:51.400> squid<00:06:51.720> doesn't
light but of course the squid doesn't
light but of course the squid doesn't
care<00:06:52.280> it's<00:06:52.440> asleep<00:06:52.840> in<00:06:52.960> the<00:06:53.080> sand<00:06:53.800> and<00:06:53.919> as<00:06:54.080> the
care it's asleep in the sand and as the
care it's asleep in the sand and as the
day<00:06:54.440> goes<00:06:54.720> by<00:06:54.960> the<00:06:55.160> bacteria<00:06:55.680> double<00:06:56.120> they
day goes by the bacteria double they
day goes by the bacteria double they
release<00:06:56.680> the<00:06:56.840> molecule<00:06:57.400> and<00:06:57.520> then<00:06:57.680> light
release the molecule and then light
release the molecule and then light
comes<00:06:58.199> on<00:06:58.599> at<00:06:58.759> night<00:06:59.080> exactly<00:06:59.680> when<00:06:59.800> the<00:06:59.919> squid
comes on at night exactly when the squid
comes on at night exactly when the squid
wants<00:07:00.599> it<00:07:01.520> and<00:07:01.639> so<00:07:01.840> first<00:07:02.039> we<00:07:02.160> figured<00:07:02.479> out<00:07:02.720> how
wants it and so first we figured out how
wants it and so first we figured out how
and<00:07:03.440> this<00:07:03.639> bacterium<00:07:04.160> does<00:07:04.360> this<00:07:04.560> but<00:07:04.680> then<00:07:04.800> we
and this bacterium does this but then we
and this bacterium does this but then we
brought<00:07:05.120> the<00:07:05.280> tools<00:07:05.560> of<00:07:05.759> molecular<00:07:06.280> biology
brought the tools of molecular biology
brought the tools of molecular biology
to<00:07:07.120> this<00:07:07.280> to<00:07:07.400> figure<00:07:07.720> out<00:07:07.960> really<00:07:08.240> what's<00:07:08.479> the
to this to figure out really what's the
to this to figure out really what's the
mechanism<00:07:09.840> and<00:07:10.000> what<00:07:10.160> we<00:07:10.360> found<00:07:10.759> so<00:07:11.000> this<00:07:11.080> is
mechanism and what we found so this is
mechanism and what we found so this is
now<00:07:11.479> supposed<00:07:11.840> to<00:07:11.960> be<00:07:12.240> again<00:07:12.479> my<00:07:12.680> bacterial
now supposed to be again my bacterial
now supposed to be again my bacterial
cell<00:07:13.840> is<00:07:13.960> that<00:07:14.120> vibrio<00:07:14.560> fishery<00:07:15.000> has<00:07:15.120> a

cell is that vibrio fishery has a
protein<00:07:15.879> that's<00:07:16.080> the<00:07:16.240> red<00:07:16.520> box<00:07:16.960> it's<00:07:17.120> an
protein that's the red box it's an
protein that's the red box it's an
enzyme<00:07:17.919> that<00:07:18.080> makes<00:07:18.360> that<00:07:18.560> little<00:07:18.800> hormone

molecule<00:07:19.879> the<00:07:20.000> red<00:07:20.240> triangle<00:07:21.160> and<00:07:21.240> then<00:07:21.400> as
molecule the red triangle and then as
molecule the red triangle and then as
the<00:07:21.680> cells<00:07:22.000> grow<00:07:22.360> they're<00:07:22.520> all<00:07:22.680> releasing
the cells grow they're all releasing
the cells grow they're all releasing
that<00:07:23.280> molecule<00:07:23.800> into<00:07:24.039> the<00:07:24.199> environment<00:07:24.720> so
that molecule into the environment so
that molecule into the environment so
there's<00:07:25.120> lots<00:07:25.319> of<00:07:25.520> molecule<00:07:26.120> there<00:07:26.840> and<00:07:26.960> the
there's lots of molecule there and the
there's lots of molecule there and the

pathogenicity with chorum sensing and so
pathogenicity with chorum sensing and so
that's<00:09:05.079> how<00:09:05.240> it<00:09:05.360> works<00:09:05.680> we<00:09:05.839> also<00:09:06.120> then<00:09:06.279> went<00:09:06.480> to
that's how it works we also then went to
that's how it works we also then went to
look<00:09:06.839> at<00:09:07.000> what<00:09:07.079> are<00:09:07.240> these<00:09:07.519> molecules<00:09:08.040> so
look at what are these molecules so
look at what are these molecules so
these<00:09:08.320> were<00:09:08.480> the<00:09:08.640> red<00:09:08.880> triangles<00:09:09.560> on<00:09:09.760> my
these were the red triangles on my
these were the red triangles on my

slides before and so this is the vibal
slides before and so this is the vibal
fisheri<00:09:12.800> molecule<00:09:13.320> this<00:09:13.440> is<00:09:13.560> the<00:09:13.720> word<00:09:14.040> that
fisheri molecule this is the word that
fisheri molecule this is the word that
it<00:09:14.320> talks<00:09:14.680> with<00:09:15.079> and<00:09:15.200> then<00:09:15.320> we<00:09:15.480> started<00:09:15.720> to
it talks with and then we started to
it talks with and then we started to
look<00:09:15.959> at<00:09:16.160> other<00:09:16.480> bacteria<00:09:17.320> and<00:09:17.440> these<00:09:17.560> are

just a smattering of the molecules that
just a smattering of the molecules that
we've<00:09:20.040> discovered<00:09:20.680> and<00:09:20.800> what<00:09:20.920> I<00:09:21.079> hope<00:09:21.279> you<00:09:21.440> can
we've discovered and what I hope you can
we've discovered and what I hope you can
see<00:09:22.240> is<00:09:22.360> that<00:09:22.519> the<00:09:22.640> molecules<00:09:23.079> are<00:09:23.279> related<00:09:24.040> so

depicted<00:10:14.160> on<00:10:14.360> this<00:10:14.519> slide<00:10:15.200> this<00:10:15.360> is<00:10:15.480> your<00:10:15.680> skin
depicted on this slide this is your skin
depicted on this slide this is your skin
so<00:10:16.560> this<00:10:16.640> is<00:10:16.880> just<00:10:17.399> a<00:10:17.560> picture<00:10:17.880> a<00:10:18.040> micrograph
so this is just a picture a micrograph
so this is just a picture a micrograph
of<00:10:18.760> your<00:10:18.920> skin<00:10:19.279> anywhere<00:10:19.600> on<00:10:19.760> your<00:10:19.920> body<00:10:20.200> it
of your skin anywhere on your body it
of your skin anywhere on your body it
looks<00:10:20.560> pretty<00:10:20.760> much<00:10:21.040> like<00:10:21.279> this<00:10:21.720> and<00:10:21.880> what<00:10:22.000> I
looks pretty much like this and what I
looks pretty much like this and what I
hope<00:10:22.320> you<00:10:22.440> can<00:10:22.600> see<00:10:22.800> is<00:10:22.920> that<00:10:23.079> there's<00:10:23.440> all
hope you can see is that there's all
hope you can see is that there's all
kinds<00:10:24.000> of<00:10:24.240> bacteria<00:10:24.839> there<00:10:25.399> and<00:10:25.480> so<00:10:25.640> we
kinds of bacteria there and so we
kinds of bacteria there and so we
started<00:10:26.079> to<00:10:26.320> think<00:10:26.640> if<00:10:26.800> this<00:10:27.000> really<00:10:27.320> is<00:10:27.560> about
started to think if this really is about
started to think if this really is about
Communication<00:10:28.519> in<00:10:28.760> bacteria<00:10:29.560> and<00:10:29.680> it's<00:10:29.880> about
Communication in bacteria and it's about
Communication in bacteria and it's about
counting<00:10:30.600> your<00:10:30.760> neighbors<00:10:31.279> it's<00:10:31.560> not<00:10:31.800> enough
counting your neighbors it's not enough
counting your neighbors it's not enough
to<00:10:32.279> be<00:10:32.480> able<00:10:32.760> to<00:10:32.959> only<00:10:33.320> talk<00:10:33.760> within<00:10:34.120> your
to be able to only talk within your
to be able to only talk within your
species<00:10:35.200> there<00:10:35.399> has<00:10:35.560> to<00:10:35.720> be<00:10:35.839> a<00:10:35.959> way<00:10:36.160> to<00:10:36.320> take<00:10:36.480> a
species there has to be a way to take a
species there has to be a way to take a
census<00:10:37.200> of<00:10:37.399> the<00:10:37.519> rest<00:10:37.720> of<00:10:37.839> the<00:10:38.000> bacteria<00:10:38.519> in
census of the rest of the bacteria in
census of the rest of the bacteria in
the<00:10:38.880> population<00:10:39.839> so<00:10:40.000> we<00:10:40.160> went<00:10:40.399> back<00:10:40.519> to
the population so we went back to
the population so we went back to
molecular<00:10:41.240> biology<00:10:41.720> and<00:10:41.839> started<00:10:42.200> studying
molecular biology and started studying
molecular biology and started studying
different<00:10:43.000> bacteria<00:10:43.880> and<00:10:44.079> what<00:10:44.200> we<00:10:44.399> found<00:10:44.800> now
different bacteria and what we found now
different bacteria and what we found now
is<00:10:45.160> that<00:10:45.399> in<00:10:45.600> fact<00:10:46.000> bacteria<00:10:46.560> are
is that in fact bacteria are
is that in fact bacteria are
multilingual<00:10:47.920> so<00:10:48.120> they<00:10:48.279> all<00:10:48.680> have<00:10:49.000> a<00:10:49.279> species
multilingual so they all have a species
multilingual so they all have a species
specific<00:10:50.360> system<00:10:50.720> they<00:10:50.839> have<00:10:50.959> a<00:10:51.120> molecule
specific system they have a molecule
specific system they have a molecule
that<00:10:51.800> says<00:10:52.120> me<00:10:52.760> but<00:10:52.880> then<00:10:53.000> running<00:10:53.399> in
that says me but then running in
that says me but then running in
parallel<00:10:54.079> to<00:10:54.279> that<00:10:54.480> is<00:10:54.600> a<00:10:54.839> second<00:10:55.200> system<00:10:55.560> that
parallel to that is a second system that
parallel to that is a second system that
we've<00:10:56.120> discovered<00:10:56.639> that's<00:10:56.920> generic<00:10:57.680> so<00:10:57.839> they
we've discovered that's generic so they
we've discovered that's generic so they
have<00:10:58.120> a<00:10:58.320> second<00:10:58.639> enzyme<00:10:59.040> that<00:10:59.320> makes<00:10:59.480> a<00:10:59.680> second
have a second enzyme that makes a second
have a second enzyme that makes a second
signal<00:11:00.839> and<00:11:01.079> it<00:11:01.200> has<00:11:01.360> its<00:11:01.519> own<00:11:01.839> receptor<00:11:02.519> and
signal and it has its own receptor and
signal and it has its own receptor and
this<00:11:03.079> molecule<00:11:03.720> is<00:11:03.880> the<00:11:04.040> trade<00:11:04.399> language<00:11:04.839> of
this molecule is the trade language of
this molecule is the trade language of
bacteria<00:11:05.959> it's<00:11:06.120> used<00:11:06.399> by<00:11:06.560> all<00:11:06.800> different
bacteria it's used by all different
bacteria it's used by all different
bacteria<00:11:07.839> and<00:11:07.959> it's<00:11:08.160> the<00:11:08.360> language<00:11:08.760> of<00:11:09.040> inter
bacteria and it's the language of inter
bacteria and it's the language of inter
species<00:11:10.440> communication<00:11:11.440> and<00:11:11.519> so<00:11:11.760> what
species communication and so what
species communication and so what
happens<00:11:12.639> is<00:11:12.760> that<00:11:13.040> bacteria<00:11:13.560> are<00:11:13.760> able<00:11:14.120> to
happens is that bacteria are able to
happens is that bacteria are able to
count<00:11:14.920> how<00:11:15.040> many<00:11:15.360> of<00:11:15.519> me<00:11:15.959> and<00:11:16.120> how<00:11:16.240> many<00:11:16.440> of<00:11:16.600> you
count how many of me and how many of you
count how many of me and how many of you
and<00:11:17.200> they<00:11:17.399> take<00:11:17.680> that<00:11:17.880> information<00:11:18.600> inside
and they take that information inside
and they take that information inside
and<00:11:19.320> they<00:11:19.560> decide<00:11:20.320> what<00:11:20.600> tasks<00:11:21.040> to<00:11:21.240> carry<00:11:21.519> out
and they decide what tasks to carry out
and they decide what tasks to carry out
depending<00:11:22.320> on<00:11:22.519> who's<00:11:22.720> in<00:11:22.839> the<00:11:22.959> minority<00:11:23.720> and
depending on who's in the minority and
depending on who's in the minority and
who's<00:11:24.079> in<00:11:24.240> the<00:11:24.399> majority<00:11:25.000> of<00:11:25.240> Any<00:11:25.560> Given
who's in the majority of Any Given
who's in the majority of Any Given
population<00:11:27.720> and<00:11:27.800> so<00:11:27.959> then<00:11:28.160> again<00:11:28.320> we<00:11:28.440> turn<00:11:28.639> to
population and so then again we turn to
population and so then again we turn to
chemistry
chemistry
chemistry
and<00:11:30.079> we<00:11:30.279> figured<00:11:30.560> out<00:11:30.760> what<00:11:30.920> this<00:11:31.160> generic
and we figured out what this generic
and we figured out what this generic
molecule<00:11:32.079> is<00:11:32.240> so<00:11:32.399> that<00:11:32.519> was<00:11:32.680> the<00:11:32.880> pink<00:11:33.240> ovals
molecule is so that was the pink ovals
molecule is so that was the pink ovals
on<00:11:33.800> my<00:11:34.000> last<00:11:34.279> slide<00:11:34.880> this<00:11:35.000> is<00:11:35.200> it<00:11:35.480> it's<00:11:35.600> a<00:11:35.880> very
on my last slide this is it it's a very
on my last slide this is it it's a very
small<00:11:36.720> five<00:11:37.079> carbon<00:11:37.480> molecule<00:11:38.320> and<00:11:38.519> what<00:11:38.680> the
small five carbon molecule and what the
small five carbon molecule and what the
important<00:11:39.200> thing<00:11:39.360> is<00:11:39.519> that<00:11:39.680> we<00:11:39.800> learned<00:11:40.240> is
important thing is that we learned is
important thing is that we learned is
that<00:11:40.680> every<00:11:41.000> bacterium<00:11:41.639> has<00:11:41.959> exactly<00:11:42.440> the
that every bacterium has exactly the
that every bacterium has exactly the
same<00:11:42.839> enzyme<00:11:43.320> and<00:11:43.440> makes<00:11:43.920> exactly<00:11:44.480> the<00:11:44.639> same
same enzyme and makes exactly the same
same enzyme and makes exactly the same
molecule<00:11:45.560> so<00:11:45.720> they're<00:11:45.959> all<00:11:46.200> using<00:11:46.639> this
molecule so they're all using this
molecule so they're all using this
molecule<00:11:47.279> for<00:11:47.519> interspecies<00:11:48.440> communication
molecule for interspecies communication
molecule for interspecies communication
so<00:11:49.600> this<00:11:49.720> is<00:11:49.920> the<00:11:50.120> bacterial<00:11:50.920> espiranto
so this is the bacterial espiranto
so this is the bacterial espiranto
and<00:11:53.720> so<00:11:53.920> once<00:11:54.120> we<00:11:54.279> got<00:11:54.519> that<00:11:54.680> far<00:11:54.959> we've
and so once we got that far we've
and so once we got that far we've
started<00:11:55.480> to<00:11:55.600> learn<00:11:55.839> that<00:11:56.040> bacteria<00:11:56.440> can<00:11:56.680> talk
started to learn that bacteria can talk
started to learn that bacteria can talk
to<00:11:57.000> each<00:11:57.120> other<00:11:57.360> with<00:11:57.480> this<00:11:57.680> chemical
to each other with this chemical
to each other with this chemical
language<00:11:58.560> but<00:11:58.680> what<00:11:58.760> we<00:11:58.880> started<00:11:59.360> think<00:11:59.519> is
language but what we started think is
language but what we started think is
that<00:11:59.800> maybe<00:12:00.040> there's<00:12:00.240> something<00:12:00.600> practical
that maybe there's something practical
that maybe there's something practical
that<00:12:01.279> we<00:12:01.399> can<00:12:01.560> do<00:12:01.839> here<00:12:02.079> as<00:12:02.240> well<00:12:02.680> so<00:12:02.880> I've<00:12:03.000> told
that we can do here as well so I've told
that we can do here as well so I've told
you<00:12:03.320> that<00:12:03.519> bacteria<00:12:03.959> do<00:12:04.160> have<00:12:04.320> all<00:12:04.480> these
you that bacteria do have all these
you that bacteria do have all these
social<00:12:05.040> behaviors<00:12:05.639> that<00:12:05.839> they<00:12:06.399> communicate
social behaviors that they communicate
social behaviors that they communicate
um<00:12:07.519> with<00:12:07.680> these<00:12:07.880> molecules<00:12:08.440> and<00:12:08.560> of<00:12:08.720> course
um with these molecules and of course
um with these molecules and of course
I've<00:12:09.160> also<00:12:09.399> told<00:12:09.639> you<00:12:09.760> that<00:12:09.880> one<00:12:10.000> of<00:12:10.120> the
I've also told you that one of the
I've also told you that one of the
important<00:12:10.720> things<00:12:11.000> they<00:12:11.120> do<00:12:11.600> is<00:12:11.720> to<00:12:11.959> initiate
important things they do is to initiate
important things they do is to initiate
pathogenicity<00:12:13.480> using<00:12:13.800> corm<00:12:14.120> sensing<00:12:14.839> so<00:12:15.000> we
pathogenicity using corm sensing so we
pathogenicity using corm sensing so we
thought<00:12:15.519> what<00:12:15.639> if<00:12:15.800> we<00:12:15.959> made<00:12:16.279> these<00:12:16.519> bacteria
thought what if we made these bacteria
thought what if we made these bacteria
so<00:12:17.399> they<00:12:17.639> can't<00:12:18.000> talk<00:12:18.399> or<00:12:18.639> they<00:12:18.839> can't<00:12:19.120> hear
so they can't talk or they can't hear
so they can't talk or they can't hear
couldn't<00:12:20.279> these<00:12:20.519> be<00:12:20.800> new<00:12:21.079> kinds<00:12:21.320> of
couldn't these be new kinds of
couldn't these be new kinds of
antibiotics<00:12:22.519> and<00:12:22.680> of<00:12:22.800> course<00:12:22.959> you've<00:12:23.199> just
antibiotics and of course you've just
antibiotics and of course you've just
heard<00:12:23.680> and<00:12:23.800> you<00:12:23.959> already<00:12:24.279> know<00:12:24.639> that<00:12:24.920> we're
heard and you already know that we're
heard and you already know that we're
running<00:12:25.480> out<00:12:25.600> of<00:12:25.800> antibiotics<00:12:26.600> bacteria<00:12:26.959> are
running out of antibiotics bacteria are
running out of antibiotics bacteria are
incredibly<00:12:27.800> multi-<00:12:28.399> drug<00:12:28.680> resistant<00:12:29.240> right
incredibly multi- drug resistant right
incredibly multi- drug resistant right
now<00:12:29.560> and<00:12:29.720> that's<00:12:29.959> because<00:12:30.279> all<00:12:30.440> of<00:12:30.560> the
now and that's because all of the
now and that's because all of the
antibiotics<00:12:31.480> that<00:12:31.600> we<00:12:31.760> use<00:12:32.440> kill<00:12:32.880> bacteria<00:12:33.600> so
antibiotics that we use kill bacteria so
antibiotics that we use kill bacteria so
they<00:12:33.920> either<00:12:34.199> pop<00:12:34.440> the<00:12:34.600> bacterial<00:12:35.079> membrane
they either pop the bacterial membrane
they either pop the bacterial membrane
they<00:12:35.760> make<00:12:35.959> the<00:12:36.199> bacterium<00:12:36.639> so<00:12:36.800> it<00:12:36.920> can't
they make the bacterium so it can't
they make the bacterium so it can't
replicate<00:12:37.639> its<00:12:37.839> DNA<00:12:38.600> we<00:12:38.760> kill<00:12:39.120> bacteria<00:12:39.600> with
replicate its DNA we kill bacteria with
replicate its DNA we kill bacteria with
traditional<00:12:40.240> antibiotics<00:12:41.000> and<00:12:41.160> that<00:12:41.399> selects
traditional antibiotics and that selects
traditional antibiotics and that selects
for<00:12:42.279> resistant<00:12:42.760> mutants<00:12:43.560> and<00:12:43.680> so<00:12:43.880> now<00:12:44.079> of
for resistant mutants and so now of
for resistant mutants and so now of
course<00:12:44.480> we<00:12:44.639> have<00:12:44.800> this<00:12:45.160> Global<00:12:45.760> problem<00:12:46.399> in
course we have this Global problem in
course we have this Global problem in
infectious<00:12:47.120> diseases<00:12:48.079> so<00:12:48.240> we<00:12:48.399> thought<00:12:48.639> well
infectious diseases so we thought well
infectious diseases so we thought well
what<00:12:48.920> if<00:12:49.040> we<00:12:49.160> could<00:12:49.360> sort<00:12:49.519> of<00:12:49.680> do<00:12:49.959> Behavior
what if we could sort of do Behavior
what if we could sort of do Behavior
modifications<00:12:51.360> just<00:12:51.519> make<00:12:51.800> these<00:12:52.079> bacteria
modifications just make these bacteria
modifications just make these bacteria
so<00:12:52.920> they<00:12:53.199> can't<00:12:53.480> talk<00:12:54.079> they<00:12:54.240> can't<00:12:54.560> count<00:12:54.920> and
so they can't talk they can't count and
so they can't talk they can't count and
they<00:12:55.240> don't<00:12:55.480> know<00:12:55.760> to<00:12:55.959> launch<00:12:56.360> virulence<00:12:57.360> and
they don't know to launch virulence and
they don't know to launch virulence and
so<00:12:57.639> that's<00:12:57.880> exactly<00:12:58.240> what<00:12:58.360> we've<00:12:58.560> done<00:12:58.760> and
so that's exactly what we've done and
so that's exactly what we've done and
we've<00:12:59.199> sort<00:12:59.320> of<00:12:59.440> taken<00:12:59.760> two<00:13:00.079> strategies<00:13:01.000> the
we've sort of taken two strategies the
we've sort of taken two strategies the
first<00:13:01.440> one<00:13:01.720> is<00:13:01.880> we've<00:13:02.079> targeted<00:13:02.560> the<00:13:02.760> intras
first one is we've targeted the intras
first one is we've targeted the intras
species<00:13:03.880> communication<00:13:04.600> system<00:13:05.120> so<00:13:05.279> we've
species communication system so we've
species communication system so we've
made<00:13:05.720> molecules<00:13:06.240> that<00:13:06.440> look<00:13:06.720> kind<00:13:06.880> of<00:13:07.160> like
made molecules that look kind of like
made molecules that look kind of like
the<00:13:07.480> real<00:13:07.800> molecules<00:13:08.480> which<00:13:08.600> you<00:13:08.760> saw<00:13:09.279> but
the real molecules which you saw but
the real molecules which you saw but
they're<00:13:09.560> a<00:13:09.680> little<00:13:09.880> bit<00:13:10.120> different<00:13:10.680> and<00:13:10.800> so
they're a little bit different and so
they're a little bit different and so
they<00:13:11.120> lock<00:13:11.399> into<00:13:11.720> those<00:13:12.000> receptors<00:13:12.600> and<00:13:12.760> they
they lock into those receptors and they
they lock into those receptors and they
Jam<00:13:13.720> recognition<00:13:14.440> of<00:13:14.560> the<00:13:14.720> real<00:13:15.000> thing<00:13:15.639> and<00:13:15.760> so
Jam recognition of the real thing and so
Jam recognition of the real thing and so
by<00:13:16.199> targeting<00:13:16.720> the<00:13:16.880> red<00:13:17.160> system<00:13:17.800> what<00:13:17.920> we<00:13:18.040> are
by targeting the red system what we are
by targeting the red system what we are
able<00:13:18.440> to<00:13:18.639> do<00:13:19.000> is<00:13:19.160> to<00:13:19.320> make<00:13:19.720> species<00:13:20.360> specific
able to do is to make species specific
able to do is to make species specific
or<00:13:21.240> disease<00:13:21.920> specific<00:13:22.720> anticor<00:13:23.360> sensing
or disease specific anticor sensing
or disease specific anticor sensing
molecules<00:13:24.600> we've<00:13:24.839> also<00:13:25.079> done<00:13:25.279> the<00:13:25.440> same<00:13:25.720> thing
molecules we've also done the same thing
molecules we've also done the same thing
with<00:13:26.079> the<00:13:26.240> pink<00:13:26.600> system<00:13:27.240> we've<00:13:27.440> taken<00:13:27.720> that
with the pink system we've taken that
with the pink system we've taken that
Universal<00:13:28.480> molecule<00:13:28.920> and<00:13:29.279> and<00:13:29.399> turned<00:13:29.680> it
Universal molecule and and turned it
Universal molecule and and turned it
around<00:13:30.120> a<00:13:30.199> little<00:13:30.399> bit<00:13:30.600> so<00:13:30.760> that<00:13:30.880> we've<00:13:31.079> made
around a little bit so that we've made
around a little bit so that we've made
antagonists<00:13:32.320> of<00:13:32.480> the<00:13:32.639> inter<00:13:33.199> species
antagonists of the inter species
antagonists of the inter species
communication<00:13:34.320> system<00:13:34.959> and<00:13:35.199> these<00:13:35.480> the<00:13:35.680> hope
communication system and these the hope
communication system and these the hope
is<00:13:36.160> that<00:13:36.360> these<00:13:36.480> will<00:13:36.639> be<00:13:36.760> used<00:13:37.160> as
is that these will be used as
is that these will be used as
broadspectrum<00:13:38.160> antibiotics<00:13:39.160> that<00:13:39.279> work
broadspectrum antibiotics that work
broadspectrum antibiotics that work
against<00:13:39.920> all<00:13:40.240> bacteria<00:13:41.160> and<00:13:41.279> so<00:13:41.399> to<00:13:41.600> finish
against all bacteria and so to finish
against all bacteria and so to finish
I'll<00:13:42.040> just<00:13:42.199> show<00:13:42.399> you<00:13:42.560> the<00:13:43.000> strategy<00:13:44.000> and<00:13:44.160> this
I'll just show you the strategy and this
I'll just show you the strategy and this
one<00:13:44.440> I'm<00:13:44.560> just<00:13:44.720> using<00:13:45.160> the<00:13:45.399> inters<00:13:45.760> species
one I'm just using the inters species
one I'm just using the inters species
molecule<00:13:46.600> but<00:13:46.760> the<00:13:47.000> logic<00:13:47.320> is<00:13:47.560> exactly<00:13:47.959> the
molecule but the logic is exactly the
molecule but the logic is exactly the
same<00:13:48.800> so<00:13:49.000> what<00:13:49.120> you<00:13:49.240> know<00:13:49.480> is<00:13:49.600> that<00:13:49.880> when<00:13:50.040> that
same so what you know is that when that
same so what you know is that when that
bacterium<00:13:50.720> gets<00:13:50.880> into<00:13:51.160> the<00:13:51.360> animal<00:13:51.759> in<00:13:51.959> this
bacterium gets into the animal in this
bacterium gets into the animal in this
case<00:13:52.440> a<00:13:52.600> mouse<00:13:53.199> it<00:13:53.320> doesn't<00:13:53.680> initiate
case a mouse it doesn't initiate
case a mouse it doesn't initiate
virulence<00:13:54.920> right<00:13:55.079> away<00:13:55.680> it<00:13:55.880> gets<00:13:56.120> in<00:13:56.440> it
virulence right away it gets in it
virulence right away it gets in it
starts<00:13:56.920> growing<00:13:57.320> it<00:13:57.440> starts<00:13:57.800> secreting<00:13:58.440> its
starts growing it starts secreting its
starts growing it starts secreting its
corn<00:13:59.120> sensing<00:13:59.480> molecules<00:14:00.279> it<00:14:00.519> recognizes
corn sensing molecules it recognizes
corn sensing molecules it recognizes
when<00:14:01.360> it<00:14:01.560> has<00:14:01.759> enough<00:14:02.160> bacteria<00:14:02.759> that<00:14:02.920> now
when it has enough bacteria that now
when it has enough bacteria that now
they're<00:14:03.240> going<00:14:03.360> to<00:14:03.560> launch<00:14:03.920> their<00:14:04.160> attack<00:14:04.600> and
they're going to launch their attack and
they're going to launch their attack and
the<00:14:04.920> animal<00:14:05.399> dies<00:14:06.199> and<00:14:06.279> so<00:14:06.440> what<00:14:06.560> we've<00:14:06.720> been
the animal dies and so what we've been
the animal dies and so what we've been
able<00:14:07.120> to<00:14:07.320> do<00:14:07.880> is<00:14:08.040> to<00:14:08.240> give<00:14:08.480> these<00:14:08.720> virulent
able to do is to give these virulent
able to do is to give these virulent
infections<00:14:09.800> but<00:14:09.920> we<00:14:10.079> give<00:14:10.240> them<00:14:10.440> in
infections but we give them in
infections but we give them in
conjunction<00:14:11.399> with<00:14:11.519> our<00:14:11.800> anti-m<00:14:12.519> sensing
conjunction with our anti-m sensing
conjunction with our anti-m sensing
molecules<00:14:13.399> so<00:14:13.560> these<00:14:13.680> are<00:14:13.880> molecules<00:14:14.399> that
molecules so these are molecules that
molecules so these are molecules that
look<00:14:14.839> kind<00:14:15.000> of<00:14:15.160> like<00:14:15.320> the<00:14:15.440> real<00:14:15.680> thing<00:14:15.920> but
look kind of like the real thing but
look kind of like the real thing but
they're<00:14:16.199> a<00:14:16.320> little<00:14:16.480> bit<00:14:16.759> different<00:14:17.120> which
they're a little bit different which
they're a little bit different which
I've<00:14:17.440> depicted<00:14:17.839> on<00:14:18.040> this<00:14:18.199> slide<00:14:18.920> and<00:14:19.040> what<00:14:19.199> we
I've depicted on this slide and what we
I've depicted on this slide and what we
now<00:14:19.560> know<00:14:20.000> is<00:14:20.120> that<00:14:20.240> if<00:14:20.360> we<00:14:20.480> treat<00:14:20.759> the<00:14:20.920> animal
now know is that if we treat the animal
now know is that if we treat the animal
with<00:14:21.480> a<00:14:21.680> pathogenic<00:14:22.279> bacterium<00:14:22.839> a<00:14:23.079> multi-drug
with a pathogenic bacterium a multi-drug
with a pathogenic bacterium a multi-drug
resistant<00:14:24.240> pathogenic<00:14:24.800> bacterium<00:14:25.759> in<00:14:26.199> the
resistant pathogenic bacterium in the
resistant pathogenic bacterium in the
same<00:14:26.600> time<00:14:26.880> we<00:14:27.079> give<00:14:27.360> our<00:14:27.720> anti-m<00:14:28.519> sensing<00:14:28.800> MO
same time we give our anti-m sensing MO
same time we give our anti-m sensing MO
molecule<00:14:29.800> in<00:14:30.040> fact<00:14:30.480> the<00:14:30.639> animal<00:14:31.040> lives<00:14:31.680> and<00:14:31.800> so
molecule in fact the animal lives and so
molecule in fact the animal lives and so
we<00:14:32.120> think<00:14:32.360> that<00:14:32.560> this<00:14:32.720> is<00:14:32.959> the<00:14:33.120> next
we think that this is the next
we think that this is the next
generation<00:14:34.000> of<00:14:34.199> antibiotics<00:14:34.959> and<00:14:35.120> it's<00:14:35.320> going
generation of antibiotics and it's going
generation of antibiotics and it's going
to<00:14:35.680> get<00:14:35.839> us<00:14:36.120> around<00:14:36.560> at<00:14:36.639> least<00:14:36.839> initially<00:14:37.399> this
to get us around at least initially this
to get us around at least initially this
big<00:14:37.959> problem<00:14:38.360> of<00:14:38.600> resistance<00:14:39.600> so<00:14:39.759> what<00:14:39.880> I<00:14:39.959> hope
big problem of resistance so what I hope
big problem of resistance so what I hope
you<00:14:40.399> think<00:14:40.680> is<00:14:40.800> that<00:14:41.079> bacteria<00:14:41.639> can<00:14:41.880> talk<00:14:42.079> to
you think is that bacteria can talk to
you think is that bacteria can talk to
each<00:14:42.440> other<00:14:42.880> they<00:14:43.040> use<00:14:43.399> chemicals<00:14:43.959> as<00:14:44.160> their
each other they use chemicals as their
each other they use chemicals as their
words<00:14:44.959> they<00:14:45.120> have<00:14:45.240> an<00:14:45.440> incredibly
words they have an incredibly
words they have an incredibly
complicated<00:14:47.079> chemical<00:14:47.480> lexicon<00:14:48.079> that<00:14:48.199> we're
complicated chemical lexicon that we're
complicated chemical lexicon that we're
just<00:14:48.720> now<00:14:48.959> starting<00:14:49.600> to<00:14:49.759> learn<00:14:50.120> about<00:14:50.920> and<00:14:51.079> of
just now starting to learn about and of
just now starting to learn about and of
course<00:14:51.519> what<00:14:51.680> that<00:14:51.839> allows<00:14:52.320> bacteria<00:14:52.800> to<00:14:53.079> do
course what that allows bacteria to do
course what that allows bacteria to do
is<00:14:53.600> to<00:14:53.880> be<00:14:54.839> multicellular<00:14:55.839> right<00:14:56.000> and<00:14:56.120> so<00:14:56.360> in
is to be multicellular right and so in
is to be multicellular right and so in
the<00:14:56.759> spirit<00:14:57.040> of<00:14:57.199> Ted<00:14:57.560> they<00:14:57.680> are<00:14:57.920> doing<00:14:58.320> things
the spirit of Ted they are doing things
the spirit of Ted they are doing things
together<00:14:59.240> because<00:14:59.519> it<00:14:59.680> makes<00:14:59.959> a<00:15:00.199> difference
together because it makes a difference
together because it makes a difference
right<00:15:01.040> so<00:15:01.639> what<00:15:01.800> happens<00:15:02.120> is<00:15:02.279> that<00:15:02.480> bacteria
right so what happens is that bacteria
right so what happens is that bacteria
have<00:15:03.199> these<00:15:03.519> Collective<00:15:04.079> behaviors<00:15:04.880> and<00:15:05.040> they
have these Collective behaviors and they
have these Collective behaviors and they
can<00:15:05.440> carry<00:15:05.720> out<00:15:06.040> tasks<00:15:06.480> that<00:15:06.680> they<00:15:06.800> could
can carry out tasks that they could
can carry out tasks that they could
never<00:15:07.519> accomplish<00:15:08.040> if<00:15:08.240> they<00:15:08.440> simply<00:15:08.880> acted<00:15:09.440> as
never accomplish if they simply acted as
never accomplish if they simply acted as
individuals<00:15:10.839> and<00:15:11.199> and<00:15:11.320> what<00:15:11.440> I<00:15:11.519> would<00:15:11.720> hope
individuals and and what I would hope
individuals and and what I would hope
that<00:15:12.120> I<00:15:12.240> could<00:15:12.600> further<00:15:13.000> argue<00:15:13.360> to<00:15:13.560> you<00:15:14.040> is
that I could further argue to you is
that I could further argue to you is
that<00:15:14.440> this<00:15:14.560> is<00:15:14.680> the<00:15:14.839> invention<00:15:15.360> of
that this is the invention of
that this is the invention of
multicellularity<00:15:16.560> bacteria<00:15:17.079> have<00:15:17.199> been<00:15:17.360> on

years humans couple hundred thousands so
we<00:15:22.600> think<00:15:22.880> bacteria<00:15:23.600> made<00:15:23.839> the<00:15:24.000> rules<00:15:24.519> for<00:15:24.720> how

and<00:15:28.360> we<00:15:28.519> think<00:15:28.720> by<00:15:29.040> studying<00:15:29.480> bacteria<00:15:30.160> we're
and we think by studying bacteria we're

multicellularity in the human body so we
multicellularity in the human body so we
know<00:15:34.880> that<00:15:35.040> the<00:15:35.199> principles<00:15:35.600> and<00:15:35.720> the<00:15:35.839> rules

of primitive organisms the hope is that
of primitive organisms the hope is that

well I hope that what you've learned is
well I hope that what you've learned is
that<00:15:46.759> bacteria<00:15:47.199> can<00:15:47.440> distinguish<00:15:48.000> self<00:15:48.360> from

that bacteria can distinguish self from

others so by using these two molecules
others so by using these two molecules
they<00:15:50.639> can<00:15:50.759> say<00:15:51.040> me<00:15:51.560> and<00:15:51.720> they<00:15:51.839> can<00:15:51.959> say<00:15:52.279> you<00:15:52.800> and
they can say me and they can say you and
they can say me and they can say you and
again<00:15:53.240> of<00:15:53.360> course<00:15:53.600> that's<00:15:53.720> what<00:15:53.880> we<00:15:54.040> do<00:15:54.319> both
again of course that's what we do both
again of course that's what we do both
as<00:15:54.759> mole<00:15:55.199> in<00:15:55.519> in<00:15:55.600> a<00:15:55.759> molecular<00:15:56.279> way<00:15:56.519> and<00:15:56.600> then
as mole in in a molecular way and then
as mole in in a molecular way and then
also<00:15:57.079> in<00:15:57.199> an<00:15:57.360> outward<00:15:57.839> way<00:15:58.279> but<00:15:58.440> I<00:15:58.560> think<00:15:58.720> about
also in an outward way but I think about
also in an outward way but I think about
the<00:15:59.160> molecular<00:15:59.680> stuff<00:16:00.160> this<00:16:00.279> is<00:16:00.519> exactly<00:16:01.000> what
the molecular stuff this is exactly what
the molecular stuff this is exactly what
happens<00:16:01.440> in<00:16:01.600> your<00:16:01.839> body<00:16:02.319> it's<00:16:02.480> not<00:16:02.639> like<00:16:02.759> your
happens in your body it's not like your
happens in your body it's not like your
heart<00:16:03.160> cells<00:16:03.440> and<00:16:03.560> your<00:16:03.720> kidney<00:16:04.000> cells<00:16:04.279> get
heart cells and your kidney cells get
heart cells and your kidney cells get
all<00:16:04.560> mixed<00:16:04.880> up<00:16:05.079> every<00:16:05.319> day<00:16:05.600> and<00:16:05.759> that's
all mixed up every day and that's
all mixed up every day and that's
because<00:16:06.360> there's<00:16:06.600> all<00:16:06.800> of<00:16:07.040> this<00:16:07.319> chemistry
because there's all of this chemistry
because there's all of this chemistry
going<00:16:08.120> on<00:16:08.639> these<00:16:08.839> molecules<00:16:09.399> that<00:16:09.560> say<00:16:09.959> who
going on these molecules that say who
going on these molecules that say who
each<00:16:10.399> of<00:16:10.600> these<00:16:10.759> groups<00:16:11.000> of<00:16:11.120> cells<00:16:11.519> is<00:16:12.000> and
each of these groups of cells is and
each of these groups of cells is and
what<00:16:12.319> their<00:16:12.560> tasks<00:16:13.040> should<00:16:13.279> be<00:16:13.839> and<00:16:13.959> so<00:16:14.240> again
what their tasks should be and so again
what their tasks should be and so again
we<00:16:14.680> think<00:16:15.079> that<00:16:15.319> bacteria<00:16:15.880> invented<00:16:16.440> that<00:16:16.680> and
we think that bacteria invented that and
we think that bacteria invented that and
then<00:16:16.959> you've<00:16:17.240> just<00:16:17.440> evolved<00:16:17.839> a<00:16:17.920> few<00:16:18.079> more
then you've just evolved a few more
then you've just evolved a few more
bells<00:16:18.519> and<00:16:18.680> whistles<00:16:19.319> but<00:16:19.480> all<00:16:19.600> of<00:16:19.759> the<00:16:19.920> ideas
bells and whistles but all of the ideas
bells and whistles but all of the ideas
are<00:16:20.680> in<00:16:20.959> these<00:16:21.240> simple<00:16:21.639> systems<00:16:22.160> that<00:16:22.319> we<00:16:22.639> can
are in these simple systems that we can
are in these simple systems that we can
study<00:16:23.839> and<00:16:23.920> then<00:16:24.079> the<00:16:24.240> final<00:16:24.560> thing<00:16:24.720> is<00:16:24.920> again
study and then the final thing is again
study and then the final thing is again
just<00:16:25.240> to<00:16:25.440> reiterate<00:16:25.959> that<00:16:26.079> there's<00:16:26.319> this
just to reiterate that there's this
just to reiterate that there's this
practical<00:16:27.079> part<00:16:27.360> and<00:16:27.480> so<00:16:27.680> we've<00:16:27.880> made<00:16:28.120> these
practical part and so we've made these
practical part and so we've made these
anti<00:16:28.920> form<00:16:29.199> sensing<00:16:29.920> molecules<00:16:30.440> that<00:16:30.560> are
anti form sensing molecules that are
anti form sensing molecules that are

being developed as new kinds of
being developed as new kinds of
Therapeutics<00:16:33.240> but<00:16:33.360> then<00:16:33.480> to<00:16:33.639> finish<00:16:33.920> with<00:16:34.079> a

also made proor sensing molecules so
also made proor sensing molecules so
we've<00:16:41.000> targeted<00:16:41.519> those<00:16:41.720> systems<00:16:42.160> to<00:16:42.319> make<00:16:42.519> the

ridiculous in the natural world it was
ridiculous in the natural world it was
done<00:17:24.640> by<00:17:24.760> a<00:17:24.959> child<00:17:25.559> so<00:17:25.919> science<00:17:26.360> is<00:17:26.559> done<00:17:26.880> by
