-!- anannie_ is now known as anannie | 00:10 | |
fredox | anannie: short answer - signal strength. needs supercondutors | 00:11 |
---|---|---|
anannie | fredox: can't you create a loop and amplify whatever tiny amount of current is generated? | 00:12 |
-!- AshleyWaffle [~quassel@unaffiliated/anastasiawyatt] has quit [Remote host closed the connection] | 00:12 | |
anannie | fredox: How low is the amount of current generated? | 00:13 |
fredox | its so small the resistance of silver is enough too block it | 00:13 |
fredox | like uA or less | 00:14 |
fredox | at mV | 00:14 |
fredox | in pulses measured in ms | 00:14 |
fredox | multiply together = ~0 | 00:14 |
anannie | So can we use gold? | 00:14 |
anannie | we use a fine gold wire with a large number of coils | 00:15 |
fredox | golds worse than silver | 00:15 |
anannie | and optimize the dimensions of the wire for this | 00:15 |
fredox | big superconductor based detectors can pick up the heartbeat from 6ft away | 00:16 |
anannie | oh sorry forgot about that | 00:16 |
gradstudentbot | I don't know what to tell you, I thought would have graduated by now. | 00:16 |
gradstudentbot | The culture got contaminated. | 00:17 |
anannie | how about this fredox I could put in a silver plate and let it generate eddy currents in that...? | 00:17 |
anannie | maybe if I detect the eddy currents by a secondary apparatus I'll be able to pick out the signal? | 00:17 |
anannie | nah that won't work | 00:18 |
anannie | what about just picking up the EM field generated by the heart using an antenna? | 00:18 |
anannie | an antenna is a completely different configuration | 00:20 |
anannie | as compared to a coil hoping to induce current using a magnetic field | 00:20 |
anannie | will that pick things up fredox ? | 00:20 |
fredox | yes | 00:21 |
fredox | will it pick up enough of a signal to distinguish it from background radiation, probably not | 00:22 |
fredox | unless as mentioned earlier its a superconducting antenna | 00:22 |
anannie | but if it's pressed against the chest surely I can filer out the background radiation? | 00:23 |
anannie | * filter | 00:23 |
anannie | background radiation is more or less constant | 00:23 |
anannie | this is variable and closer | 00:24 |
anannie | I'm talking about shrinking all of this and turning it into a pendant that can be worn around the neck | 00:24 |

rigel | anyone following the cultured beef story? | 05:44 |
rigel | fwiw, i think it's pretty hilarious. | 06:17 |
rigel | a bunch of hype about a lab grown beef slab | 06:17 |
rigel | and they just avoid talking about the fact that they needed a bunch of FBS and antibiotics to grow it in the first place | 06:17 |
rigel | so, ethical "benefits" are out the window, as are resource use arguments, since it still requires baby cows | 06:18 |

@kanzure | drazak: welcome back? | 08:46 |
drazak | kanzure: kinda, long time no see | 08:46 |
@kanzure | sup/how goes? | 08:47 |
drazak | not bad, living in vancouver | 08:47 |
drazak | thinking of going back to college | 08:47 |
@kanzure | have you met derek jacoby? | 08:47 |
drazak | not yet | 08:47 |
@kanzure | he's somewhere in vancouver doing a biotech hackerspace | 08:47 |
drazak | oh cool | 08:48 |
drazak | will have to find out about that | 08:48 |
drazak | decided to trawl through recent diybio posts | 08:48 |
drazak | you saw the one from avery louie the other day? | 08:48 |
drazak | that gel is fucking awful | 08:48 |
@kanzure | haha | 08:48 |
drazak | tell me I'm wrong :P | 08:49 |
@kanzure | nope | 08:49 |
@kanzure | avery tends to be methodical, so i'm not sure what's going wrong here | 08:50 |
drazak | I should ask for a copy of his proceedures and see what I can find | 08:50 |
drazak | kanzure: is there sitll a fucking top posting argument going on as well? | 08:51 |
drazak | there's like 1/10 posts that're top posted | 08:52 |
@kanzure | unfortunately nobody understood what top/bottom posting meant | 08:52 |
drazak | yeah | 08:53 |
drazak | and leitl coming in and rules naziing, which is good | 08:53 |
drazak | (about top posting ironically) | 08:53 |
drazak | kanzure: you know I speak my mind on these things, too, if your work looks awful I'm gonna tell you it's fucking awful | 09:00 |
@kanzure | hm? | 09:01 |
@kanzure | if you have some criticism, pile it on | 09:01 |
@kanzure | but i don't see anything yet? | 09:01 |
drazak | oh I'm gonna post in a sec | 09:01 |

@kanzure | drazak: i expected more from you | 09:46 |
drazak | kanzure: meh I didn't want to dig too hard in my first post in... 3 years? | 09:47 |
@kanzure | nobody will remembre you | 09:47 |
@kanzure | *remember you | 09:47 |
drazak | yeah I know | 09:47 |
drazak | kanzure: to be frank if people posted their lab notebook with their experiment that'd be great | 09:48 |
drazak | kanzure: because otherwise nobody has any idea what in the fuck they're doing | 09:49 |

@kanzure | agreed | 09:51 |
drazak | kanzure: you see the one the other day about someone looking for bacteria for a control? | 09:56 |
@kanzure | a control? | 09:57 |
@kanzure | oh, a control in a project | 09:57 |
@kanzure | no | 09:57 |
drazak | er, bacterial dna as a control | 09:57 |
drazak | not the bug | 09:57 |
@kanzure | nope. why do you mention it? | 09:57 |
drazak | but you could just culture the bacteria and extract the dna | 09:57 |
drazak | looked like it was bsl2 bacteria, prolly gonna have a hard time getting it without having a lab | 09:58 |
drazak | pretty sure some bacteria is gonna cost a lot less than the bacterial dna | 09:59 |
@kanzure | we should be working on that synthesizer | 10:00 |
drazak | there's a synthesizer project? | 10:01 |

@kanzure | https://github.com/kanzure/paperbot | 10:06 |
drazak | ah | 10:09 |
drazak | nice nod to venter | 10:10 |
@kanzure | we were talking with his company but the call didn't go well (ancient history) | 10:11 |
drazak | lol | 10:12 |
drazak | didn't you meet him once | 10:12 |
@kanzure | nope not venter | 10:12 |
drazak | have you actually gotten anywhere with microfluidic chips | 10:12 |
@kanzure | no, i don't think microfluidics is the right v1 | 10:12 |
drazak | agreed | 10:12 |
drazak | the problem with the oone time costs method | 10:13 |
@kanzure | huh? | 10:13 |
drazak | is that you also need a nice microscope to check if your microfluidics arrays are correct | 10:13 |
drazak | page 21 of your pdf | 10:13 |
@kanzure | that's okay, i am willing to own a nice microscope | 10:13 |
drazak | oh? you are? I'm surprised :P | 10:13 |
@kanzure | why's that? | 10:14 |
drazak | I'm kidding | 10:14 |
@kanzure | the real problem with microfluidics is the number of revisions to get it to work, and the cost per revision | 10:14 |
@kanzure | per prototype i mean | 10:14 |
drazak | yea | 10:14 |
drazak | h | 10:14 |
@kanzure | and then the number of bugs that will pop up that you can't fix | 10:14 |
@kanzure | i mean, there's enough problems with the chemistry itself | 10:14 |
drazak | it's pretty bad | 10:15 |
@kanzure | a 12 step process with 5 inputs? yeah, good luck. | 10:15 |
drazak | my uncle had some arrays way back when | 10:15 |
drazak | it was like 2 inputs and all it had to do was let cells adhere to it | 10:15 |
drazak | so they could pass other cells through it | 10:15 |
drazak | and it took 30ish revisions | 10:16 |
@kanzure | http://diyhpl.us/wiki/dna-synthesis.html | 10:16 |
drazak | fix mod_rewrite | 10:16 |
@kanzure | huh? | 10:16 |
drazak | gets rid of the .html at the end | 10:16 |
@kanzure | that already works, though | 10:17 |
@kanzure | maybe i wanted to type .html? | 10:17 |
drazak | oh ok | 10:17 |

chris_99 | i'm curious how fast that kind of tissue would grow | 12:07 |
ParahSailin | you will never produce tissue culture muscle flesh cheaper than chicken meat from entire animals | 12:10 |

@nmz787 | drazak: vancouver WA or BC? | 12:30 |
@nmz787 | fredox: yes kanzure was right, i've been targeting 1 micron cubed, it has millisecond diffusion times, and reagent savings are 10^6 even with like 66% yield per addition step | 12:31 |
@nmz787 | over $.30 per base | 12:31 |
rigel | ParahSailin: the use of FBS, as i noted above, was critical to this lab-beef (as it is to much of tissue culture) | 12:32 |
rigel | i liken it to building a giant fan to power your windmills | 12:32 |
ParahSailin | rigel: yeah pretty much | 12:32 |
@nmz787 | why dont people just grow CNS deficient cows? | 12:32 |
ParahSailin | have you seen how dumb cows are? | 12:32 |
@nmz787 | but the arguments are about pain or ending their consciousness | 12:33 |
ParahSailin | oh | 12:33 |
@nmz787 | so just remove that sensor | 12:33 |
rigel | there are two arguments | 12:33 |
rigel | one is about ethics | 12:33 |
ParahSailin | well thats just silliness and irrational sentiments | 12:33 |
@nmz787 | isnt the ethics one re pain? | 12:33 |
rigel | the other is about resource costs and meeting demand, which is supposed to increase | 12:33 |
@nmz787 | no nerves, no pain | 12:33 |
-!- randalla1ordon [~randall@71-34-95-45.ptld.qwest.net] has joined ##hplusroadmap | 12:33 | |
rigel | the ethics one is mooted by the use of FBS | 12:33 |
chris_99 | what's CNS nmz787? | 12:33 |
@nmz787 | no one bitches about all the soy babies 'edamame' people eat | 12:34 |
@nmz787 | central nervous system | 12:34 |
rigel | i made a joke about how if you don't name the cow it doesnt have a soul yet | 12:34 |
@nmz787 | rigel: ahh i see, diff issue | 12:34 |
chris_99 | how would that work, nmz787? | 12:34 |
ParahSailin | oysters are pretty efficient at meat production and they're practically vegetables | 12:34 |
@nmz787 | chris_99: i imagine you'd lose the jaw mastication thing with no nerves, but factory farming can probably pre-grind all the food | 12:35 |

ParahSailin | dumber cow = chicken | 12:36 |
rigel | so this is really all just science as conspicuous consumption | 12:36 |
@nmz787 | ParahSailin: but not ethically | 12:36 |
@nmz787 | but chickens are a decent example of working without having a head | 12:36 |
ParahSailin | dont dignify irrational sentimentality with ethics | 12:36 |

@nmz787 | pshh | 12:37 |
chris_99 | nmz787, wasn't he not actually headless then | 12:37 |
@nmz787 | is that where pain is felt? | 12:37 |
@nmz787 | chris_99: i guess if what ParahSailin said is true | 12:37 |
@kanzure | i don't understand what you're trying to argue for | 12:38 |
@kanzure | whether or not they feel pain is immaterial to how much meat they produce | 12:38 |
gradstudentbot | I forgot to make a control group. | 12:38 |
@nmz787 | 'This includes the corticospinal tract (motor), the posterior column-medial lemniscus pathway (fine touch, vibration sensation and proprioception) and the spinothalamic tract (pain, temperature, itch and crude touch). ' | 12:38 |
@nmz787 | :( | 12:38 |
ParahSailin | kanzure: some people thing feeling pain is the essential quality that determines whether we should treat something as another human or not | 12:38 |
@nmz787 | kanzure: the arguments veggie people make is about hurting the organism though IME | 12:38 |
@kanzure | are you angry that other lifeforms have neurons? i don't understand your moral objection to chickens having neurons. | 12:39 |
@nmz787 | i dont, since i feel plants are dying just the same | 12:39 |
@nmz787 | i ate a shitload of raspberrie fetuses yesterday | 12:39 |
@nmz787 | fetal rasperry serum with frozen and churned cow teat serum is amazing | 12:40 |
