Not sure if this belongs in this thread but it is biology related and it is cool. https://digitalcommons.fairfield.edu/cgi/viewcontent.cgi?article=1294&context=engineering-facultypubs Magnetotaxis as a Means for Nanofabrication >Magnetotactic bacteria (MTB), discovered in early 1970s contain single-domain crystals of magnetite (Fe3O4) called magnetosomes that tend to form a chain like structure from the proximal to the distal pole along the long axis of the cell. The ability of these bacteria to sense the magnetic field for displacement, also called magnetotaxis, arises from the magnetic dipole moment of this chain of magnetosomes. In aquatic habitats, these organisms sense the geomagnetic field and traverse the oxic-anoxic interface for optimal oxygen concentration along the field lines. Here we report an elegant use of MTB where magnetotaxis of Magnetospirillum magneticum (classified as AMB-1) could be utilized for controlled navigation over a semiconductor substrate for selective deposition. We examined 50mm long coils made out of 18AWG and 20AWG copper conductors having diameters of 5mm, 10mm and 20mm for magnetic field intensity and heat generation. Based on the COMSOL simulations and experimental data, it is recognized that a compound semiconductor manufacturing technology involving bacterial carriers and carbon-based materials such as graphene and carbon nanotubes would be a desirable choice in the future.

>>31589 >these organisms sense the geomagnetic field and traverse the oxic-anoxic interface for optimal oxygen concentration along the field lines. That's amazingly-interesting. BTW, I wasn't even aware that oxygen molecules would congregate there. Some type of oxygen ions interacting with the field lines I suppose? Thanks, Ribose! >=== -minor edit

https://www.independent.co.uk/tech/robot-mushroom-biohybrid-robotics-cornell-b2610411.html https://www.science.org/doi/10.1126/scirobotics.adk8019 >Many biohybrid robots are powered by animal or plant cells, which are sensitive to specific culture procedures and limited to short life spans. In contrast, fungi can be easily cultured and are robust in extreme conditions. Taking advantage of fungal mycelia’s natural light sensitivity, Mishra et al. developed an electrical interface to both house the mycelia and measure their electrophysiological action potentials. A control model was then developed to use the rhythmic voltage spikes from the living mycelia to control the locomotion of both a soft starfish-inspired robot and a wheeled robot. Robot trajectories could be altered by stimulating the mycelia with ultraviolet light. —Melisa Yashinski

>>34219 Heres something you should keep an eye on. A human connectome would allow a computer to simulate an entire human brain if it bares fruit.

>>34222 >digits There's about a Zeta of synaptic interconnections within the human connectome. AFAICT, we have the most sophisticated -- by far -- neural systems on the planet. So it probably stands to reason that there's much that could be learned by using human neural tissue for such experiments. Thanks for the information, Anon! Cheers. :^)

The very first commercially available biocomputer has been released by cortical labs for "only" $35,000. Cortical labs is also planning to offer wetware as a service. https://gigazine.net/gsc_news/en/20250305-cortical-labs-cl1/

>>37355 Certainly sounds intriguing, Anon. OTOH, I'm wondering just where they 'sourced' those human brain cells for their culture. Skimming the article, I didn't see mention of that. Thanks for the information, Anon! Cheers. >=== -add'l edit

>>37355 >>37356 At what point does it become a "real" brain that's enslaved? As much I love AI and robotics, I don't want WH40K Servitors.

>>37356 They probably got the neurons off of thermofisher or another supplier. https://www.thermofisher.com/us/en/home/life-science/cell-culture/primary-cell-culture/neuronal-cell-culture.html

>>37362 From what I read; the suppliers got the cells from (hopefully) donors.

>>37363 Most cell cultures are from donors. You would have to find out what cell line the neurons came from to make sure they don't come from an unborn baby or something horrible.

>>37364 OK I pulled up the paper with the pong game also done by Cortical Labs. https://www.cell.com/neuron/fulltext/S0896-6273(22)00806-6?_returnURL=https%3A%2F%2Flinkinghub.elsevier.com%2Fretrieve%2Fpii%2FS0896627322008066%3Fshowall%3Dtrue They use human-induced pluripotent stem cells (hiPSCs) https://en.m.wikipedia.org/wiki/Induced_pluripotent_stem_cell These are from adult donors.

>>37366 That's good! Nice research :)

>>37355 If only I had the money

>>37369 If you could find an alternative to the vacuum chamber step you might just be able to build your own. https://pmc.ncbi.nlm.nih.gov/articles/PMC8925300/ >Construction and Implementation of Carbon Fiber Microelectrode Arrays for Chronic and Acute In Vivo Recordings >Multichannel electrode arrays offer insight into the working brain and serve to elucidate neural processes at the single-cell and circuit levels. Development of these tools is crucial for understanding complex behaviors and cognition and for advancing clinical applications. However, it remains a challenge to densely record from cell populations stably and continuously over long time periods. Many popular electrodes, such as tetrodes and silicon arrays, feature large cross-diameters that produce damage upon insertion and elicit chronic reactive tissue responses associated with neuronal death, hindering the recording of stable, continuous neural activity. In addition, most wire bundles exhibit broad spacing between channels, precluding simultaneous recording from a large number of cells clustered in a small area. The carbon fiber microelectrode arrays described in this protocol offer an accessible solution to these concerns. The study provides a detailed method for fabricating carbon fiber microelectrode arrays that can be used for both acute and chronic recordings in vivo. The physical properties of these electrodes make them ideal for stable and continuous long-term recordings at high cell densities, enabling the researcher to make robust, unambiguous recordings from single units across months

>>37379 >Development of these tools is crucial for understanding complex behaviors and cognition and for advancing clinical applications. Heh, good luck with that! As a Substance Dualist, I argue that without the intangible 'spark' of the immaterial parts of the human soul, at best you'll only achieve an animated, zombie-esque, especially-clever automaton -- if human-tier """cognition""" is truly your endgoal. >tl;dr Fat chance, through any naturally-derived means. <---> OTOH, if we can reliably achieve the behavioral characteristics of a gud doggo for our robowaifus, then we will have managed a major breakthrough in bio-psycho-neuro studies! At this point, even achieving something like a good birb's perception/reaction systems would be a yuge.step.forward. <---> In the meantime, we are extremely-likely IMO to be able to achieve highly-satisfying & functional 'mind' simulacrums, for pleasing & effective robowaifus in the nearterm-ish, say 10 year's time (shorter even, if the subject population of consumers is constrained to only autists like myself [& most of Anonymous]). >ttl;dr Robowaifus are inevitable, all else being equal.

>>37480 That's pretty interesting. Can you give us the >tl;dr for waste management for such devices?

>>37359 > Servitors The thing is: It's just cells, not a full human brain. The real issue would be keeping those alive, cleaning and replacing. I like this thread and it's good we have it, but it's very experimental and fringe. Biology should only be used very sparsely, and only if there are real advantages. >>37492 >waste management for such devices It seems to consume itself and the carrier material, so basically rot away. Which isn't necessarily a problem if it's cellulose based material. Imagine, you want a sensor in nature and reduce the amount of garbage and no need to collect it later. Or consider that most people on the planet are not good at keeping their garbage out of places where it shouldn't go. Now, if they want to power a small device it's better to give them something that doesn't even require a complex recycling procedure. But also, if it's easier to build locally by makers it creates less dependencies, logistic costs and would be cheaper. For all topics here in this thread, in relation to robowaifus, I think the standard solution for waste is to make it flushable and have her pee it out. Of course, if it can be broken down internally to a less repulsive state it's preferable to do so.

>>37535 POTD Highly-insightful take on the waste issues involved, and of this entire topic generally. The idea of using this as some type of thirdie smol power supply is very intriguing IMO. GG, NoidoDev. Cheers. :^)

>>37535 >The thing is: It's just cells, not a full human brain. Then the question is, what counts a human brain. How many neurons does it take? Oddly reminds me of the abortion debate.

>>37540 >How many neurons does it take? Well according to MIT [1], the average brain has ~ 86.1 +/- 8.1 billion neuronal cells (~ x2) within it's constituent tissue. However, the brain of homo sapiens sapiens isn't your standard brain, and the so-called 'connectome' [2] of the human brain is currently estimated at around 1 Zeta [3] of synaptic interconnections. >tl;dr Its not enough just to slop a bunch of tissue together (even if you could manage to keep it all alive); you still have to have a lifetime's worth of human experiences to "program" it properly! :^) --- 1. https://teachmesomething.mit.edu/tms/how-many-neurons-are-there-human-brain/ 2. https://pmc.ncbi.nlm.nih.gov/articles/PMC3555558/ 3. That's 21 zeros, ie; 1'000'000'000'000'000'000'000

>>37549 That's astounding. God designed a supercomputer beyond our wildest fantasies, and make it fit into a bowling ball, and made it run on the power of 4 smartphones

>>37551 Very well-put, Anon, >That's astounding. It truly is. Beyond imagination, really.

>>37549 So basically a robowaifu with an organic brain would be a baby youd have to raise

>>37556 Assuming it was a fully organic brain then yes, but if computers were used to help it train you could accelerate the training time table. Keep in mind biocomputers are brain cells on a microelectrode array. Gene editing might also help speed things up.

>>37556 Roughly-speaking -- all else being equal -- yes. --- However, there's much more to the human soul than simply our brains! While we can simulate this missing sekrit sauce with an amalgam of various techniques for our robowaifus (and btw quite-satisfactorily for the average male or child, I deem), yet we'll never create that 'spark' of humanity that makes us, well, human. No natural means at our disposal can provide that invisible illumination that radiates from all real humans. >tl;dr Its complicated! :^)

Cortical Labs claims to have working computers of silicon + human neurons. https://corticallabs.com/cl1.html Where did these human neurons come from, I'm wondering?

>>38233 Have they solved the telomere issue? I see that iPSCs are claimed to foster telomerase production. From what I gather, any offspring created through these synthesized gametes would still suffer premature aging with lower life expectancy. Exciting progress overall. I can't help but wonder what the true solution to the telomere dilemma will be. Perhaps a customized bacterium which produces proteins needed to alleviate the myriad issues inherent to iPSCs derived clones? I trust your instincts more than my own on this subject so, I want to know your thoughts.

>>38241 Telomerase is not turned off in all of your cells. Telomerase is active in stem cells, T cells, and a couple others in rare cases.
