1
00:00:00,080 --> 00:00:06,160
this is no regular pc coolant but rather

2
00:00:04,279 --> 00:00:10,880
bioluminescent coolant that you are about to watch us create with the help

3
00:00:08,320 --> 00:00:15,280
of the genetically engineered bacteria that is behind us over there

4
00:00:13,280 --> 00:00:21,760
it isn't the kind of thing you'd run in your pc 24 7 at least not exactly like

5
00:00:18,400 --> 00:00:23,279
this but the biotechnology involved blew

6
00:00:21,760 --> 00:00:29,119
my mind so let's have a chat about how we built the

7
00:00:25,920 --> 00:00:30,640
world's first bioluminescent gaming pc

8
00:00:29,119 --> 00:00:34,719
or as i call it the anglerfish

9
00:00:32,960 --> 00:00:39,360
they don't have claws it's more like teeth but minor details

10
00:00:37,440 --> 00:00:43,200
minor details like our sponsor war thunder war thunder is an online

11
00:00:41,360 --> 00:00:47,039
military vehicle combat game that's free to play and a ton of fun try it out for

12
00:00:45,280 --> 00:00:51,719
free down below today and get some special bonus items for signing up

13
00:00:58,640 --> 00:01:03,920
let's go back in time to before the anglerfish came to life though today

14
00:01:02,239 --> 00:01:09,920
we're joined by the fine folks from nioka Labs whose main area of focus is

15
00:01:07,119 --> 00:01:13,760
creating a sustainable glow stick by using bioluminescence to create the

16
00:01:11,920 --> 00:01:17,600
light instead of harsh chemicals that can seep into the environment after

17
00:01:15,280 --> 00:01:21,759
disposal in nature whether we're talking about a bacteria or a jellyfish

18
00:01:19,520 --> 00:01:27,360
bioluminescence is created by combining two main compounds luciferin and

19
00:01:24,240 --> 00:01:29,360
luciferase these are generic catch-all

20
00:01:27,360 --> 00:01:33,200
words to describe actually a wide variety of different chemicals kind of

21
00:01:31,200 --> 00:01:37,360
like how we say a battery has to have an anode and a cathode but the exact

22
00:01:35,680 --> 00:01:41,680
materials that they're made of can vary greatly the combo we're using today is

23
00:01:39,360 --> 00:01:46,880
derived from gaussian princeps a deep sea crustation that naturally glows blue

24
00:01:45,040 --> 00:01:51,520
the only challenge is that these guys wouldn't be particularly happy trapped

25
00:01:48,960 --> 00:01:57,280
inside a glow stick or your computer so instead the folks from nioka Labs take

26
00:01:53,920 --> 00:02:00,159
the natural recipe from these guys and

27
00:01:57,280 --> 00:02:04,240
then they get bacteria to fart out those same compounds that are needed to

28
00:02:01,920 --> 00:02:08,640
produce the reaction the first step of this process is locating the chunk of a

29
00:02:06,560 --> 00:02:13,520
creature's dna that is responsible for bioluminescence to find the specific

30
00:02:11,280 --> 00:02:19,200
sequence you need one protein to separate the two strands of dna and read

31
00:02:15,920 --> 00:02:20,879
a single strand creating rna the rna is

32
00:02:19,200 --> 00:02:24,640
the code that will produce another protein that will execute a function in

33
00:02:22,800 --> 00:02:29,360
the cell when bioluminescence is occurring you freeze the cell read the

34
00:02:27,280 --> 00:02:33,519
rna that's floating around in there and then you try to link it to the function

35
00:02:31,280 --> 00:02:37,680
of interest once you've figured out what bit of genetic code is responsible for

36
00:02:35,200 --> 00:02:41,440
bioluminescence you order a primer off the internet which contains short

37
00:02:39,760 --> 00:02:46,800
segments of the dna you need to make copies of along with dna segments that

38
00:02:44,319 --> 00:02:52,480
are already present in the bacteria you then take a boatload of the dna primer

39
00:02:49,680 --> 00:02:56,959
and chuck it into this guy right here the thermal cycler

40
00:02:54,640 --> 00:03:01,760
this bad boy heats up the dna to around 100 degrees celsius at which point the

41
00:02:59,440 --> 00:03:05,440
double strands separate into single strands because they can't stay together

42
00:03:03,760 --> 00:03:10,239
at such high temperatures then you just get to hope that when it

43
00:03:08,480 --> 00:03:14,560
cools back down the segments from your primer dna will bind to the regions of

44
00:03:12,800 --> 00:03:18,640
the longer dna strands that are complementary

45
00:03:15,840 --> 00:03:24,319
from here a protein comes in and repairs the dna turning that single strand back

46
00:03:21,440 --> 00:03:30,080
into a double strand and in the process adding the bit of dna code that you need

47
00:03:26,879 --> 00:03:32,480
for bioluminescence do this 20 or so

48
00:03:30,080 --> 00:03:36,720
more times and you get loads of copies of the dna that you want to put into

49
00:03:34,239 --> 00:03:42,319
your bacteria to make it glow from here you shoot all that dna into

50
00:03:39,360 --> 00:03:46,799
the bacteria essentially injecting code and the bacteria will read that code and

51
00:03:44,560 --> 00:03:52,239
create the luciferase needed for our bioluminescent reaction but enough talk

52
00:03:50,159 --> 00:03:56,720
let's do it thanks to reductions in the cost of equipment and supplies this kind

53
00:03:54,640 --> 00:04:01,920
of biological science can actually be performed at home all you will need is

54
00:03:59,439 --> 00:04:05,599
some pipettes oops some pipette tips

55
00:04:03,760 --> 00:04:10,080
some kind of media so this is essentially the food for our live

56
00:04:07,599 --> 00:04:13,599
bacteria we'll get to those in a moment you'll need some live bacteria as well

57
00:04:12,159 --> 00:04:17,120
as a oh centrifuge and

58
00:04:15,760 --> 00:04:21,040
naturally safety equipment safety first ladies and

59
00:04:19,120 --> 00:04:25,440
gentlemen now obviously we're going to do this cooking show style since you

60
00:04:22,720 --> 00:04:30,240
guys don't want to wait 24 hours for our dna altered e coli to grow in our

61
00:04:27,360 --> 00:04:35,280
nutrient solution here so we would then take that which instead of looking like

62
00:04:33,280 --> 00:04:39,759
mildly dehydrated but still relatively healthy pee would look like extremely

63
00:04:38,080 --> 00:04:44,240
cloudy you need to go see your doctor pee we take that we throw it into our

64
00:04:42,080 --> 00:04:48,240
centrifuge here for probably somewhere in the neighborhood of

65
00:04:46,320 --> 00:04:52,400
five ten minutes something along those lines we pour off the extra and we end

66
00:04:50,880 --> 00:04:57,919
up with this concentrated e coli

67
00:04:55,360 --> 00:05:02,479
oh don't worry this is not the pathogenic kind this is like

68
00:05:00,000 --> 00:05:07,120
specifically engineered to be safe otherwise they wouldn't let me handle it

69
00:05:06,080 --> 00:05:10,639
right that's true that's true so i will not be

70
00:05:09,360 --> 00:05:13,600
making any unscheduled visits to the bathroom

71
00:05:12,720 --> 00:05:20,800
now oh it stinks okay we can actually use this to create a

72
00:05:18,080 --> 00:05:24,800
reaction check this out so we've got uh hold on i've got my

73
00:05:22,199 --> 00:05:30,000
luciferase and i've got my uh luciferin i want my luciferin i'm gonna

74
00:05:27,280 --> 00:05:32,479
take a hundred microliters of this they don't believe i can do it properly i

75
00:05:31,520 --> 00:05:38,160
know it i'm gonna go down to the first stop

76
00:05:35,720 --> 00:05:41,120
slowly draw wow look at that the system works it's

77
00:05:39,680 --> 00:05:45,520
right at the mark is that is that what it's supposed to do

78
00:05:42,880 --> 00:05:50,320
all right cool here we go then we're going to drop this puppy in here

79
00:05:48,320 --> 00:05:54,560
see you later and watch this oh wow you can actually

80
00:05:52,320 --> 00:05:57,440
see it's working already what yeah yeah yeah yeah don't worry i got

81
00:05:55,840 --> 00:06:02,400
this i got this oh you know i'll shake it first then we'll hit the light

82
00:05:59,520 --> 00:06:06,520
okay go for it go for it oh there's another light damn

83
00:06:06,800 --> 00:06:12,920
whoa that is sick

84
00:06:10,960 --> 00:06:14,560
get it because it's e coli

85
00:06:14,560 --> 00:06:22,560
and this is a completely organic reaction right

86
00:06:20,000 --> 00:06:25,440
glow overheat right that makes sense enzymes see i remember a couple of

87
00:06:24,080 --> 00:06:28,960
things from uh you know grade 10 science

88
00:06:29,440 --> 00:06:35,280
i've been informed it's not heat speeding up the reaction it's actually

89
00:06:32,639 --> 00:06:39,039
oxygen that causes the luciferin to glow more brightly oh wow it's already dying

90
00:06:38,000 --> 00:06:46,800
it's dying oh it's back whoa okay hold on a second whoa whoa

91
00:06:44,160 --> 00:06:49,759
whoa okay so let's just get some oxygen into it no no don't

92
00:06:48,560 --> 00:06:54,560
worry i'm not gonna i'm not gonna i wasn't gonna do that okay but now we'll

93
00:06:52,560 --> 00:06:58,400
probably have more oxygen in the air in here so we shake it do we get a brighter

94
00:06:56,800 --> 00:07:01,960
glow ah hard to say

95
00:07:03,759 --> 00:07:06,319
there it goes

96
00:07:08,960 --> 00:07:16,319
so good for you you made an unhealthy pee looking disease vial that glows

97
00:07:14,319 --> 00:07:20,639
obviously this is not the end game so the next step is we run this through

98
00:07:18,560 --> 00:07:24,319
what's called a nickel column our protein was engineered with a histidine

99
00:07:22,560 --> 00:07:28,560
tag and that is going to be naturally attracted to the nickel along the

100
00:07:26,639 --> 00:07:32,160
outsides of this column as we're pouring it through so what we can do is we pour

101
00:07:30,560 --> 00:07:37,840
the whole thing through all the garbage makes it through to the end then we

102
00:07:34,319 --> 00:07:39,360
actually sever that histidine tag and we

103
00:07:37,840 --> 00:07:42,720
wash it through and we end up with nothing but our

104
00:07:40,960 --> 00:07:47,280
luciferase so this should give us a much stronger

105
00:07:45,919 --> 00:07:53,280
reaction right you guys aren't you guys aren't setting me up here to do a lame demo are you

106
00:07:51,280 --> 00:07:57,520
they wouldn't do that they seem like nice people uh this is my

107
00:07:55,680 --> 00:08:02,639
10 microliters okay just 10 microliters this time

108
00:08:04,879 --> 00:08:09,639
this is the tricky part okay we're ready

109
00:08:12,400 --> 00:08:19,280
there's just one site on our protein where the reaction takes place so you're

110
00:08:17,280 --> 00:08:23,599
gonna see that if we if we kept this completely still

111
00:08:20,960 --> 00:08:27,360
um the like the end product would end up kind of gunking it up and that yellow

112
00:08:25,680 --> 00:08:30,400
glow would actually go away after a while but if we mix it

113
00:08:28,960 --> 00:08:35,360
things get really interesting okay let's kick the lights oh yeah you can actually oh that's so

114
00:08:33,440 --> 00:08:39,680
cool you can see where it's kind of seeping down into it

115
00:08:37,120 --> 00:08:42,320
okay ready oh wow

116
00:08:42,880 --> 00:08:50,720
that's fantastic and it's not cloudy

117
00:08:47,760 --> 00:08:55,440
no trip to the doctor today and the best part is because of the

118
00:08:52,640 --> 00:08:59,279
washing process there is no e coli inside it

119
00:08:57,760 --> 00:09:01,920
honestly though my kids aren't that into yellow glow sticks

120
00:09:00,880 --> 00:09:05,120
so um what can we do about that

121
00:09:04,240 --> 00:09:10,800
oh let's try another color shall we they wouldn't let us do science with our

122
00:09:08,720 --> 00:09:14,240
LTT Store water bottle but they're they're great for drinking out

123
00:09:12,080 --> 00:09:17,040
of all right we've got to use we'll use your flask

124
00:09:19,760 --> 00:09:25,760
there's no pipetting this is just like a dried ready to rock glow stick

125
00:09:27,040 --> 00:09:36,760
oh damn wow the green one's really bright

126
00:09:32,800 --> 00:09:36,760
holy smokes

127
00:09:37,440 --> 00:09:44,320
whoa that is awesome

128
00:09:42,240 --> 00:09:47,440
holy crap i bet you can even see my face andy

129
00:09:45,600 --> 00:09:51,399
okay let me crank it oh my god

130
00:09:51,680 --> 00:09:55,040
oh that is so cool

131
00:09:55,279 --> 00:10:02,240
so then conceivably if you wanted to make like a liter of this

132
00:09:59,600 --> 00:10:05,519
you could just you could do that yeah

133
00:10:03,040 --> 00:10:10,160
this one lasts about 20 minutes okay can you make it last longer

134
00:10:07,920 --> 00:10:16,880
yes so there's a lot of chemistry that goes on it goes into the glow reaction

135
00:10:13,920 --> 00:10:21,600
and by adjusting the additives uh in the reaction we maybe we may be able to make

136
00:10:19,440 --> 00:10:26,079
it glow for longer right or conceivably you could design

137
00:10:24,079 --> 00:10:30,399
you know glow stick capsules that have like a slow release mechanism of some

138
00:10:27,839 --> 00:10:36,560
sort or something along those lines too so also engineering the actual enzyme to

139
00:10:33,839 --> 00:10:36,560
work better

140
00:10:36,959 --> 00:10:43,440
right it's never been done before right so we're already seeing load times that

141
00:10:41,120 --> 00:10:47,920
are really really long like beyond five hours but now we're working to make it

142
00:10:45,360 --> 00:10:50,640
brighter and like more awesome got it

143
00:10:49,279 --> 00:10:55,600
i guess i saw it at the beginning of the video so there's no real surprise to

144
00:10:52,560 --> 00:10:58,160
spoil can we put it in the computer now

145
00:10:55,600 --> 00:11:02,720
let's do it uh oh what the computer's not done alex you had one job

146
00:11:00,959 --> 00:11:07,440
research the video get in touch with these guys write the video build the

147
00:11:04,880 --> 00:11:10,240
computer wrangle me

148
00:11:08,959 --> 00:11:14,839
one job all right let's have some fun here ladies and gentlemen

149
00:11:16,079 --> 00:11:22,000
all right uh hit me with maybe like 300 mils this time

150
00:11:20,480 --> 00:11:26,079
we're gonna we're gonna launch our own line of like graduated cylinders and

151
00:11:23,920 --> 00:11:30,079
beakers for you guys okay so this is where things get a little bit

152
00:11:27,839 --> 00:11:33,839
trickier yeah we're gonna have to run it for a little bit to kind of kick some of

153
00:11:31,920 --> 00:11:38,399
these bubbles out of here okay so so far we've put in what 1300

154
00:11:35,680 --> 00:11:43,839
mils something like that oh no 1200. here we go ladies and gentlemen

155
00:11:40,959 --> 00:11:43,839
uh well

156
00:11:45,040 --> 00:11:51,839
no it's not nowadays

157
00:11:49,440 --> 00:11:56,160
why did it stop and start again okay now we have water on our motherboard

158
00:11:54,160 --> 00:12:00,720
the good news is i think the GPU backplate took the brunt of that

159
00:11:59,360 --> 00:12:03,839
um that's only five mils

160
00:12:04,079 --> 00:12:09,399
is there a way to all that is five mils

161
00:12:10,639 --> 00:12:17,600
oh god this is going to take forever okay well

162
00:12:15,200 --> 00:12:22,560
oh there we go beautiful okay funnel section the good news is we're close

163
00:12:20,959 --> 00:12:25,639
does anyone still know how much water is in here

164
00:12:27,200 --> 00:12:32,560
oh god i have to get all of that in there funnel me

165
00:12:31,440 --> 00:12:35,760
okay okay it's a little smelly

166
00:12:37,040 --> 00:12:41,680
um so do you want to do just a little bit at first and should we do you want

167
00:12:40,320 --> 00:12:44,880
to turn the system off how do you guys want to do this what's going to give us

168
00:12:43,360 --> 00:12:48,079
max effect here this is the big moment

169
00:12:48,639 --> 00:12:57,120
oh that is super cool

170
00:12:54,320 --> 00:12:57,120
okay here we go

171
00:12:59,200 --> 00:13:02,800
are you getting this andy get a close-up

172
00:13:03,200 --> 00:13:07,639
i'm gonna give it another little jet here

173
00:13:09,120 --> 00:13:15,639
okay i'm going i'm going for it now

174
00:13:22,800 --> 00:13:27,519
that is freaking bright

175
00:13:30,240 --> 00:13:35,440
oh that is so cool is the density of this one like uh

176
00:13:34,480 --> 00:13:37,920
higher or something

177
00:13:38,800 --> 00:13:43,760
but why is it sitting at the bottom like that it's time

178
00:13:44,959 --> 00:13:50,079
oh look we spilled some

179
00:13:48,320 --> 00:13:53,040
now that's an easy way to find a leak in your water cooling system

180
00:13:56,480 --> 00:14:01,440
that is so cool

181
00:14:01,680 --> 00:14:07,040
that is a very different effect isn't it

182
00:14:05,040 --> 00:14:15,040
compared to when you have like a uv light and then a uv reactive additive in the

183
00:14:10,800 --> 00:14:17,839
water because the the water itself

184
00:14:15,040 --> 00:14:17,839
is what's glowing

185
00:14:19,440 --> 00:14:23,839
that is crazy cool

186
00:14:24,000 --> 00:14:30,079
now obviously constantly topping up your computer's

187
00:14:27,519 --> 00:14:35,440
enzymes is not a very practical way to get it to light up not to mention that

188
00:14:32,560 --> 00:14:39,519
once you've got micro particles whipping around in your loop

189
00:14:37,199 --> 00:14:43,279
the damage to your CPU block is going to make the rust in our whole room water

190
00:14:40,880 --> 00:14:48,480
cooling system look like a piece of cake but it's not like this is being sold as

191
00:14:45,760 --> 00:14:53,440
an ek cryo fuel competitor so the good news for nyoka's plan

192
00:14:51,040 --> 00:14:58,079
creating glow sticks is that for that use it might just be perfect in your

193
00:14:56,480 --> 00:15:03,120
typical dollar store glow stick the chemicals used to create the light

194
00:15:00,560 --> 00:15:07,360
effect are so nasty that it's probably a good thing that we couldn't find a

195
00:15:04,639 --> 00:15:11,120
proper recipe in this classic episode of Channel Super Fun

196
00:15:08,800 --> 00:15:14,560
and even worse to contain these chemicals very sturdy plastic is needed

197
00:15:13,760 --> 00:15:20,000
so every time a glow stick gets cracked

198
00:15:17,760 --> 00:15:26,399
it'll be bright and admittedly very fun for an hour or two

199
00:15:23,360 --> 00:15:29,040
then it'll sit not breaking down for a

200
00:15:26,399 --> 00:15:34,639
thousand years the bio-based fluid however is much less toxic i mean you

201
00:15:32,240 --> 00:15:39,680
could take the contents of an ioka glow stick like this one and just dump it

202
00:15:37,760 --> 00:15:44,560
afterwards or even drink it if you really wanted to and the plastic around

203
00:15:41,839 --> 00:15:50,079
it is biodegradable too it's also even possible to use this method thank you to

204
00:15:47,360 --> 00:15:54,079
create reusable glow sticks since you can just flush the glow solution down

205
00:15:51,920 --> 00:16:00,560
the drain and fill it again to recharge it now admittedly these glow sticks aren't

206
00:15:57,920 --> 00:16:04,639
cost effective at the moment but this technology has the potential to scale

207
00:16:02,320 --> 00:16:07,600
really well and glow sticks are just one example of the type of reaction that can

208
00:16:06,399 --> 00:16:12,240
be made more sustainable using biotechnology everything from clothing

209
00:16:09,839 --> 00:16:16,959
to pharmaceuticals to literal burgers can be made in this fashion haha um i

210
00:16:15,440 --> 00:16:21,839
made you guys watch a science lecture disguised as a computer video gotcha and

211
00:16:19,920 --> 00:16:26,399
now it's over for this message from our sponsor war thunder war thunder is a

224
00:17:13,199 --> 00:17:17,919
actually made a fair bit of progress since we made that but it's still really cool
