archelschris_99: this is closer to bodymod than anything else. the EEs in this community are obviously stuck at Arduino level05:44
chris_99heh yeah, i wouldn't say adding some leds has much to do with biology05:46
archelswell, implanting LEDs is all well and good, I have no gripes with that05:48
chris_99sure, but it's not really biohacking05:48
archelsjust the way in which these guys are carrying it out, with a battery that runs out before long—and mostly the stupidly large sizes of the objects they're sticking under their skin05:48
archelssure, but it could conceivably work in symbiosis with it in the near future, e.g. when it comes to optogenetics05:49

chris_99nmz787_i, i had more of a look through that patent it seems they actually are using microlenses, which maybe is novel08:40
chris_99actually i guess some image sensors have those anyway (such as Canons), maybe it just helps reduce noise08:44
nmz787_ii saw that they said 'lenses' but then their comment about no dispersive elements made me think twice08:58
nmz787_ibut yeah microlenses are nothing new08:58
chris_99mmm08:59
chris_99i still don't understand the figures, theres something which looks like a big lens09:01
nmz787_ithe Lytro is a commercial camera with microlenses09:02
chris_99yeah Canon cameras use them09:02
chris_99too09:02
chris_99not for plenoptic stuff09:03
chris_99but for capturing more light afaik09:03
nmz787_iyeah09:03
nmz787_iI think that is pretty common for DSLRs09:03
chris_99which might be what theyre using them here for?09:03
nmz787_ibut that is on the CCD, not further away09:03
nmz787_iif that is what they're doing, idk09:03
chris_99mmm09:03
nmz787_ieven in the Toshiba CCD datasheet I think they recommend an on-chip microlens09:04
nmz787_imaybe they don't call it 'micro'09:04
chris_99ah didn't notice that09:04
nmz787_iI think they showed a half-cylinder lens though, or maybe that image is from a spectrometer building guide09:04

andaresHey, I haven't been able to find much info on ways of assembling arbitrary DNA fragments in cells using something like light to control from the outside12:16
andares(So that you don't need to synthesize oligomers inorganically)12:17
andaresAre there approachrs12:17

kanzureandares: https://groups.google.com/group/enzymaticsynthesis12:19
kanzurechemical oligonucleotide synthesis is always organic chemistry12:19
kanzurealso, dna fragment assembly is usually a separate technique from oligomer synthesis12:20
-!- haskel [~haskell@203.188.241.206] has joined ##hplusroadmap12:20
kanzuree.g. see gibson assembly, cycling ligase reaction, extension pcr, etc.12:20
kanzurehttp://diyhpl.us/wiki/dna/synthesis/notes/12:21
haskelguys, how can we push h+ as fast and as hard as we can?12:21
haskelI don't want to be sitting around, as the clock ticks away12:21
kanzurehaskel: http://diyhpl.us/wiki/transhumanism has an overview, but other than that i would say cheap simplified dna synthesis, more open-source software and more open-source hardware.12:22
haskelkanzure, dna synthesis is just one step, how do you deliver that to all cells in the body? there needs to be cheap/robust/effective means of gene delivery12:23
kanzurewhy do you need to deliver to *all* cells in the body? what12:24
haskelkanzure, if you want a genetic upgrade, it seems reasonable you need for that to happen in most places of your body, unless you're targeting a specific organ or so12:24
kanzureif you need for some crazy reason (btw, i can't really think of a good reason) to deliver genomic changes to every single cell in the entire body, then the ideal method to use would be in-vitro fertilization and somatic cell nuclear transfer prior to the development of an embryo12:25
haskelkanzure, a bit late for us12:25
haskelkanzure, virus based gene delivery is as close as it gets12:25
kanzurewell then stop making ridiculous demands like "every cell"12:25
haskelkanzure, dont set goals low12:25
haskelkanzure, it is theoritcally possible, not practically possible atm, but I think we can aim to get higher and higher coverage12:26
kanzuresounds like you don't actually want the "every cell" requirement?12:26
haskelkanzure, I think its a goal to work towards12:26
haskelkanzure, precision is key to modifying biology, let's rub a little cream here and there and that will do the trick won't get you anywhere12:27
kanzurewhich gene therapy technique uses a cream? i don't understand.12:27
haskelkanzure, not speaking about gene therapy in specific, but more generally, i.e. topical is not the solution12:28
andaresGibson assembly starts with small preexisting overlapping oligomers though right kanzure?12:30
haskelkanzure, my point is once you've synthesized a desired gene, what are you going to do next with it?12:30
andaresCould those themselves be endogenously produced by bacteria and selected somehow?12:30
kanzurehaskel: i don't think that gene therapy vectors are a useful contribution, unless you have a unique method. dna synthesis continues to be too expensive to generate anything in bulk. that's the bottleneck at the moment.12:31
andaresThanks for the link anyways12:31
andaresOmg inkjet DNA synthesizer. Neat12:31
haskelkanzure, assume you take care of that, what then, now you have a ton of some desirable gene X, how do you get it to the cells that need that upgrade?12:31
kanzurehaskel: "what are you going to do next" it doesn't matter. having the tool is extremely important to the debug/test/build lifecycle. turning on that lifecycle is way more important than giving everyone projects ahead of time.12:31
fenni disagree, gene therapy vectors are very important even with "minor" changes to one or two nucleotides (very important if it's a disease-causing mutation)12:31
kanzurehaskel: but if you insist, http://diyhpl.us/wiki/dna/projects/#igem-201312:32
kanzurehaskel: i thought you were already aware of gene therapy... why are you asking me?12:32
haskelkanzure, I get your point, both are important, and from my understanding we can synthesize genes (perhaps not cheaply); so that bit is possible, but there is a delivery black hole that needs to be addressed12:33
kanzurefenn: gene therapy vectors are useful, but i don't see any suggestion here for how to make them cheaper or whethre their cost of synthesis is too high in the first place. so i'm not sure what you're trying to add to haskel's statements.12:33
kanzuregene therapy vectors are not a black hole12:33
kanzurehttp://diyhpl.us/~bryan/papers2/gene-therapy/12:34
fenni'm just saying the quantity of DNA is not the limiting factor with gene therapy12:34
haskelfenn, agree 100%12:34
kanzurewhy bring up quantity of dna?12:35
haskelkanzure, we need A and B for something to happen, A is possible (we can precisely construct DNA/RNA with precise codes) but not efficiently, B is still a bit elusive, so don't you think B deserves attention?12:35
kanzurei'm fairly happy with current gene therapy methods.12:35
andaresI want to try some out12:36
kanzurewhy?12:36
andaresRNAi seems rather accessible12:36
andaresTo make changes, of course! :)12:36
andaresI am interested in knocking out DMRT112:36
haskelkanzure, so let's take the precise DNA/RNA codes we are pretty confident about, and deliver them? why not go for the full proof of concept? instead of focusing on the part thats done but maybe not as efficiently as you like12:36
kanzurei think you would have a neasier time finding someone to test gene therapy on you, than the difficulty you would face finding someone to give you gene therapy treatment for something specific that you choose.12:36
haskelkanzure, I don't believe that at all12:37
kanzureso i suggest if you really want to try gene therapy out for whatever reason, you focus on not picking the target type or treatment type.12:37
kanzurehuh? there are already clinical trials for gene therapy, there just isn't "pick your own gene therapy target" out there at the moment, unless you do it yourself. but he said "i want to try some out", so i assumed he was talking about the thing i said (current stuff).12:37
haskelkanzure, I could get into dna synthesis right now if I wanted to, I have no idea how to start delivery12:37
andaresKanzure, I was thinking DIY (or rather, pipe-dreaming)12:38
kanzureer, what's wrong with the gene therapy literature i just linked you to?12:38
kanzureandares: i see. that makes more sense to me.12:38
kanzureandares: re: gibson assembly, see https://en.wikipedia.org/wiki/Gibson_assembly12:38
andaresBasically, I'd need to get a 25bp DNA fragment synthesized. Then an RNA polymerase kit for producing dsRNA12:38
andaresthen produce SNALP vesicles using some lipids, that teflon machine and a micropore filter12:39
andaresThen mix in the dsRNA with the SNALPs in solution, sonicate and inject12:40

andaresNot really out of the realm of feasibility for DIY, just dangerous12:41
haskelkanzure, here's a target: telomerase gene therapy, we can precisely print he dna to create telomerase, so we're done right? since delivery is so easy and not an issue and easier than the former?12:41
kanzurehaskel: because i don't see much value in "full proof of concept". i'm completely convinced that gene therapy works for certain definitions of work. telomerase gene therapy is completely unconvincing, though.12:41
haskelkanzure, because i don't see much value in "full proof of concept" are you serious?12:42
kanzure"full proof of concept" is fine if you have a good target-- but so far, nobody has a good target.12:42
kanzureyes, i'm completely serious. telemorase is not a good "proof-of-concept" target.12:42
haskelkanzure, so what's the point if we just want to toy around with and not do anything with it?12:42
haskelkanzure, why not full proof of concept? wtf12:42

kanzurei think you're just making stuff up.12:43
haskelkanzure, please enlighten me12:43
kanzureevidence includes things like how you thought gene therapy was a black hole....12:43
kanzurewell i linked you to a bunch of papers on gene therapy12:43
haskelkanzure, it's far from solved buddy12:44
haskelkanzure, are you an expert in gene therapy?12:44
fenn"The DMRT1 gene is critical in the male sex determination and without this gene the default female characteristic takes over and male characteristic is slight or non-existent." i think i see where this is going... however, "When a DMRT1 gene is lost the most common disease is chromosome 9p deletion, which causes abnormal testicular formation and feminization." so you're too late, the damage has12:44
fennbeen done, pick a different target12:44
kanzurehaskel: fuck experts12:44
haskelkanzure, and there we go12:44
andaresKanzure, is the DNA inkjet printer being worked on actively?12:44
kanzuremost experts can't even be bothered to read most of the literature- it's just authority bullshit12:44
haskelkanzure, for h+ to get anywhere things need to be approached scientifically, rigorously12:45
kanzureandares: uh depends on your definition of active!12:45
kanzurehaskel: that has fucking NOTHING to do with "experts" you coward12:45
andaresFenn, you are mostly correct. But see http://www.nature.com/nature/journal/v476/n7358/full/nature10239.html12:45
haskelkanzure, so you've bothered to read most of the literature, and "experts" havent?12:45
kanzurehaskel: but yes, i've read a lot about gene therapy. at the moment i wouldn't consider myself able to talk with gene therapy "experts" because my mind is full of fluff from dna synthesis and bitcoin, but i could brush up pretty quick i think.12:46
andaresHere we show that sexual fate is also surprisingly labile in the testis: loss of the DMRT1 transcription factor3 in mouse Sertoli cells, even in adults, activates Foxl2 and reprograms Sertoli cells into granulosa cells. In this environment, theca cells form, oestrogen is produced and germ cells appear feminized. 12:46
kanzurehaskel: yeah, one of the things that aubrey de grey is quick to point out is that a lot of gerontology people don't actually read the literature. it's an important step to understand wtf is going on.12:46
haskelkanzure, why do you think gene therapy/delivery is done?12:46
kanzurehaskel: anyway, it's 100% wrong to conclude that only "experts" can do science. correctness is something that exists independent of any institutionally-granted titles.12:46
andaresNeat stuff, eh fenn?12:46
kanzurehaskel: asking whether i am an "expert" is just.. stupid. who the shit cares whether i am an expert? what's important is my level of correctness.12:47

kanzurehaskel: i am also completely unconvinced that i'm "focusing only on one part of a bigger picture". that's an absurd claim, and you need to give some serious evidence to back up that claim for me to accept it.12:48
kanzureandares: yes there are people around who have put in work towards that printer12:48
kanzureandares: at the moment the printer is on hold namely because we never found the right chemist to hire, and also because the assembly steps were not completely designed12:49
kanzureer, dna assembly, not machine assembly12:49
haskelkanzure, please enlighten me then, on what you think the bigger picture is, what you work on, and why that is moving things forward as fast as possible?12:49
andaresKanzure, ah for the annealing?12:49
kanzurehaskel: you can't just wave your hand and get magical phenotype changes. that's not how biology works. nobody knows the exact mapping from genotype to phenotype for all possible changes. telomerase changes aren't going to produce easily observable effects for a long, long time. it's a bad "proof of concept".12:50

andaresHaa, true12:53
andaresAh the lavish life of an industry programmer12:53
haskelkanzure, yet it's worked on mice, so what do you think is a better proof of concept; or do you think that doesn't matter, let's just focus on efficiently printing genes and not worry about anything else?12:54
haskeldon't get me wrong, efficently printing genes is important, but I think there is a lot more to it12:54
fennhaskel the point of making lots of DNA cheaply is to speed up research in general12:54
haskelfenn, what research are we speeding up?12:55
fennoh little problems like "what is aging"12:55
fenn"how does the brain work" etc12:55
haskelfenn, that's a bit vauge, printing genes efficiently does not equate to automatic results for "what is aging"12:55
fennof course not12:55
fennbut if you're involved in active research you need to print a lot of genes12:56
kanzuredna synthesis is required because you must have dna molecules to build proteins, molecular machines, reprogram other cells in bulk. you need to do this at large-scale because we currently don't know (or may never know) the actual rules of biochemistry and biophysics. instead, we can iterate over large possibility spaces to find the features and functions that we desire.12:56
kanzureresearch prospects are v. important to speed up, but there's a lot of low-hanging engineering fruit, telomerase doesn't seem to be one of them- mouse results are OK, but i don't care. show me a better demo, like restoring color/infrared vision.12:57
haskelfenn, kanzure, we are able to print genes, and the efficiency is getting there very quickly: http://www.npr.org/sections/health-shots/2015/05/07/404460240/dna-printing-a-big-boon-to-research-but-some-raise-concerns13:01
haskelkanzure, " telomerase doesn't seem to be one of them- mouse results are OK" can you be a bit more specific?13:01
haskelkanzure, I used the specific example of a mouse to give some evidence, can you give a specific example why telomerase gene therapy isn't worth exploring atm?.13:02
kanzurethe mouse results for telomerase modification seem to be OK results, but i don't have 200 years to wait to see whether that works for humans13:02
haskelspecific example/reason whatever13:02
kanzureold people are already way too damaged for those results to matter anyway; it's like trying to fix a 747 crashing into the ocean by flipping a light switch or something.13:03

kanzureoh what was the final price?13:04

-!- erasei [~erasei@x.kaw.cc] has joined ##hplusroadmap13:05
kanzurehaskel: not really; you can perform a lot of rejuvenation work on super old people. but telomerase ain't going to be enough. it's not enough to show results in aging populations, in my opinion. unless you do large-scale statistical studies i guess... but i don't care about populations, i care about individuals.13:05
fennhaskel: anyway after seeing many corporations implement stuff i wanted to do and then ultimately fail or "pivot" or just not do the right thing, i realized it's important to be able do things that need to be done even if it seems like someone else is doing that13:06
kanzureyeah my lack of progress re: speculation on anti-aging therapies has lead me to believe that cryonics will probably be working long before anti-aging.13:06
kanzurehowever, my "young blood rejuvenation" ideas might be an interesting approach towards super-old rejuvenation; however, requires large-scale selective breeding, and i still think cryonics is a better use of that sort of facility, ahead of "young blood rejuvenation" breeding attempts.13:07
haskelkanzure, so you want dramatic results like a old person becoming "young" again, and the best approach to that is investigating printing dna (which is done, though not as efficient as you like, though companies are bridging that efficiency gap very very quickly)13:07
kanzureno, i don't want old->young, i think that's stupid13:07
kanzuredna synthesis is a requirement for working with biological systems. no exception.13:08
haskelkanzure, and dna synthesis is done13:08
kanzurethat there are companies that sell you 1500 bp dna for $5000 is not interesting... that's useless. you can't do anything interesting with that unless you have like $200 billion.13:08
haskelkanzure, the efficiency bit will get there very soon with a lot of for-profit companies at it13:08
kanzurewhich companies do you have in mind? cambrian genomics? oops. twist biosciences? itdna?13:09
haskelkanzure, copying and synthesizing dna are two different things buddy, you pay for 1 synthesized bit, replicate it for much cheaper chemically13:09

kanzurehaskel: we have already explained to you the "then what" part. what was wrong with the previous explanations?13:10
haskelkanzure, you did not explain, you said gene therapy is done, I asked you about that two times why you think it's done, care to elaborate?13:10
kanzurewe seem to be having two wildly different conversations......13:10
kanzureno, "then what" was not a question about gene therapy. you asked "then what" about desktop dna synthesis.13:11
fennit's way past my bedtime and this conversation is way too confrontational and too fast to keep up with13:11
kanzurecan't blame you, seeya13:11
haskelfenn, later, sorry if it is coming off as conforntational, just trying to understand13:11
andaresKanzure, re: DNA synthesis. I'm still not sure I understand if there are any approaches that don't involve externally synthesizing the DNA and then using a vector13:12
kanzurehaskel: i think you would be wise to drop the accusational tone and look more closely at existing technology. also, you should not assume that telomerase is a magic silver bullet. results come from broad technology fundamentals building up over time and technical tools becoming better, not from riding a magic bullet into the singularity.13:12
andaresI was thinking along the lines of toggling in a sequence via light pulses at a bacterial colony13:12
andaresThe Gibbs method seems like it could be a useful component of this13:13
kanzureandares: https://groups.google.com/group/enzymaticsynthesis discusses some theoretical ways to do in vivo dna synthesis as well as other ways to hijack proteins to synthesize both dna, rna and proteins; for example, electronically-controlled and light-controlled polymerase have been proposed, unfortunately nobody knows how to make that work yet.13:13
andaresAh, missed that link before. Thanks13:13
haskelkanzure, telomerase is one direction of many agreed, I mentioned that to give a specific example when you said there are no good gene therapy targets atm13:14
* fenn puts in a good word for GDF1113:14

fennandares i think you'll have to either be very clever with multiple unusual DNA polymerases, or solve the protein folding problem and build a light-directed DNA synthase from scratch13:17
kanzureand http://diyhpl.us/~bryan/papers2/DNA/ http://diyhpl.us/~bryan/papers2/polymerase/ for good measure13:17
kanzureandares: this one also applies to you, http://diyhpl.us/~bryan/papers2/polymerase/13:17
andaresYeah, and I just saw one thread about hijacking telomeraaw13:18
haskelkanzure, I understand there are technical challenges that need to be overcome to print dna, but creating copies is cheap, so with existing tech we can for relatively low cost print dna, then make as many copies as we want to play around with13:18
kanzurehaskel: the problem is one of programming ("which changes?")13:19
andaresApparently it appends 6 nts, and through some magic you can make it an arbitrary 613:19
haskelkanzure, that's an informatics problem13:19
kanzureno... it's not an informatics problem.13:19
haskelkanzure, ......13:19
kanzurebioinformatics is not going to tell you which changes you want that don't already exist13:19
fenncue bad metaphor quote13:19
kanzurethe jrayhawk quote?13:19
haskelkanzure, so what will tell us if not computational methods that can make sense of the huge web of gene/protein etc. interactions?13:20
kanzurelarge-scale dna synthesis of millions of competing different sequences.13:21
andaresthanks again.for all these links, kanzure. You're the best!13:21
haskelkanzure, now is the 1st time you give me a direct statement on how large-scale dna synthesis can be used for practical gain13:21
haskelkanzure, so you're approach is to make dna printing cheaper, print out all sorts of de novo dna, and try them out?13:22
kanzuresort of? i mean, the other reason to have large-scale dna synthesis is for genome synthesis reasons. and then test variations of genomes in microbes and so on. these can be symbiotes of most kinds.13:23
kanzurebut also many other uses of microbial genome synthesis13:23
haskelkanzure, I don't disagree with that, I think you would also need methods of automatically doing that, so you can try out millions of different things in millions of different cells, and then automatically keep track of results13:23
kanzuresuch as downloading genes from the interwebs (instead of begging for plasmids from gated communities)13:23
kanzureyes, it's true that you need to use automation, see http://diyhpl.us/~bryan/papers2/microfluidics/13:24
haskelkanzure, thank you for clarifying your approach, that was what I was trying to get at with "what next", so the what next is: print all sorts of de novo dna and try them out, brute force an understanding of life13:24
kanzurei already mentioned large-scale dna synthesis as necessary for exploring possibility space, ctrl-f on http://gnusha.org/logs/2015-11-16.log13:25
kanzurefor my own purposes i don't really care about understanding (although it's important), i care about engineering13:25
kanzureso e.g. large-scale dna synthesis can be used for the construction of molecular nanotechnology based on proteins13:25

kanzurei dunno, i'm still fond of my ping pong ball sorting machine concept13:29
haskelkanzure, fenn, but you need a system, you can't manually try out all sorts of de novo dna, unless you are using computational methods to engineer the de novo dna, so if you are not using computational methods, you need automation to try out the de novo dna, and if you do that in a large enough scale, then it is essentially brute force13:30
kanzurenobody disagreed about calling it bruteforce13:30
kanzurefenn's disagreement was with your claim that bruteforcing was the goal13:30
fenni guess kanzure and i have a slightly different vision13:30
kanzurewell, reducing research costs is important, but i want to actually use this stuff for my own insane engineering reasons13:31
fenni would use computational methods to engineer the DNA13:31
kanzurei am v. selfish13:31

fenni am not convinced that telomerase is important, but gene therapy needs some work for sure13:42
haskelfenn, agreed, I definitely think telomerase is worth exploring, it's had an effect on mice, and it has a clear physical link to cell aging, and there is a clear method to restore telomeres13:43

fennwell DMAE but they're practically the same thing13:46
andaresOh, do you send away for your "app" to be synthesized?13:47
haskelfenn, but choline is involved in a lot of things, whereas literally the only purpose of telomerase is to restore telomeres which shorten each time the cell divides, that can't be good for your genes13:48
fennuh that doesn't sound like the biology we all know and love13:49
fenn"the only purpose" is your simplified mental model13:49
Aurelius_Work'literally the only purpose' makes me twitch and I don't even know/like biology13:50
FourFire...13:50
haskelfenn, it's been a while for me, is there any other established role of telomerase ?13:50
FourFirehaskel, the mammilian cell isn't even fully mapped, by anyone.13:50
fenni have no idea what telomeres are for13:50
fenn(yes i know about the hayflick limit)13:50
haskelfenn, they are the buffer zone to your actual genes13:51
haskelfenn, each time the cell divides they get a bit shorter13:51
FourFireAFAIK the telomere is a correlation assumption: "oh the dna gets fucked up when these things run out, then that must be why blah blah"13:51
haskelFourFire, well dna gets shorter, so eventually that will eat into useful genes right?13:52
haskelFourFire, so a way to prevent that is to lengthen the telomeres, which I understand telomerase will do13:52
FourFirehaskel, sure, but it's a massive assumption to believe that is the sole, or evne main purpose of a given molecule.13:52
kanzurehaskel: what exactly was your objection to whole body stem cell replacement therapies? e.g. http://www.sens.org/research/research-blog/aged-stem-cells-and-niches-rejuvenated-systemic-factors-implications-wilt13:53
kanzureoh wait, bad link13:53

kanzureuh apparently i don't have a WILT paper... wtf.13:54
fennyeah linking to a video is surprising from you13:54
kanzurewell, i literally can't find a thing about WILT13:55
haskelFourFire, is there any other established role of telomerase? (there may be some other role telomerase plays, but I think atm that is the only role we have established)13:55
kanzureand sens foundation is still around13:55
kanzureso lack of availability of WILT explanation is really surprising13:55
fenn'telomeres may have a role in the prevention of cancer. This is because the telomeres act as a sort of time-delay "fuse"'13:55
FourFirehaskel, I don't know, I think it's unknown in general, a great deal about Mammal cells is unknown in general13:56
kanzureworld-class scientific modeling there, folks13:56
haskelfenn, but is that not through the same mechanism of action, keep telomeres long?13:56
fennaubrey's solution is to kill telomerase because tumors use it to bypass the hayflick limit13:56
kanzureand also replace all yer stem cells once a decade because loldamage13:56
haskelfenn, aubrey is not god, and in fact he looks like the spitting image of a snake oil salesman to me13:57
kanzurenobody claimed he was god13:57
kanzureperhaps you are confusing him with father time?13:57
fennwell whatever, i'm just explaining what WILT is so you don't have to watch a video13:57
haskelfenn, sorry for coming off a bit harsh, thanks for the explanation13:58
FourFireI want to substantially change how DNA information is stored13:58
kanzureFourFire: have you considered using molecules?13:58
haskelFourFire, indeed, my point is simply that atm it is the only established role13:58
haskelFourFire, which is in contrast to many other chemicals/proteins which play multiple multiple roles13:59
FourFireI'd like to, if I can do it quickly enough, find a way to store the three bit encoding across a parity of multiple DNA molecules for each given sequence (so duplicate chromosomes) but I don't know exactly how that's going to work.13:59
FourFirehaskel, sure.13:59

kanzure"Given the problems with DBS research, and with growing evidence of bias in much clinical trial research conducted, it's perhaps no surprise that many of the doctors and specialists involved in these DBS trials were paid by device manufacturers and/or provided with research funding.
