Can We Create Artificial Life with Bioelectricity? Summary
- Beyond Traditional Definitions: The question forces us to rethink what we mean by “life” and “artificial.” Are we talking about creating something entirely from scratch, or manipulating existing biological systems?
- Not “Frankenstein”: This isn’t about stitching together body parts. It’s about understanding and harnessing the fundamental principles of biological organization.
- Bioelectricity as a Control Mechanism: Bioelectric signals – patterns of voltage across cells – play a crucial role in shaping living organisms. Manipulating these signals offers a powerful way to control biological form and function.
- “Living Machines”: We’re already creating “living machines” – like xenobots and anthrobots – by rearranging existing cells and exploiting their inherent self-organizing abilities.
- Synthetic Biology: This is a key area of research in *synthetic biology* – the design and construction of new biological systems.
-
Bottom-Up vs. Top-Down:
- Bottom-Up: Trying to build life from scratch, molecule by molecule (extremely difficult).
- Top-Down: Using existing cells and manipulating their bioelectric signals to create new forms and functions (more feasible in the short term).
- The “Anatomical Compiler” Vision: The long-term goal is to develop something like an “anatomical compiler” – a system that can translate a desired biological structure into a set of bioelectric instructions.
- Ethical Considerations: Creating or manipulating life raises profound ethical questions about our responsibilities and the potential consequences.
- Partial, synthetic “life” vs “Life”: Discussions often centre around how to “define”, or even distinguish, bioelectricity as part of research.
- Beyond structure, organization, behaviours: There also remains crucial philsophical concepts that go beyond structure and “behaviors”, consciousness/cognition.
Redefining “Life” and “Artificial”: What Do We Mean?
The question “Can we create artificial life with bioelectricity?” immediately forces us to confront some fundamental questions: What do we *mean* by “life”? And what do we mean by “artificial”?
Traditionally, we’ve distinguished between “living” things (organisms that grow, reproduce, and adapt) and “non-living” things (rocks, machines, etc.). But the line is becoming increasingly blurred, especially as we learn more about the fundamental principles of biological organization.
Are we talking about creating life *entirely from scratch* – building a cell from individual molecules? That’s an incredibly challenging task, and we’re still a long way from achieving it. Or are we talking about something more subtle – taking existing biological components (cells) and rearranging them, manipulating their communication, to create something *new* and *functional*?
Not Frankenstein: Building with Biology, Not Body Parts
It’s important to dispel the image of “Frankenstein” – stitching together body parts to create a monster. That’s *not* what we’re talking about here. We’re talking about understanding and harnessing the *fundamental principles* of biological organization, not just assembling pre-existing parts.
Michael Levin, in his various publications, online talks, considers these implications, and defines very carefully about distinctions, about a latent property/ability – to “bring out” surprising and unqiue behaviors or outcomes – when cells no longer undergo usual restrictions; to do those cutting edge research is never a “playing god”. His concept on possibilities in nature has powerful and far-reaching applications. To do the research represents a search, a finding of such inherent existing capacity (within, not designed). These include discussions regarding concepts including:
- Latent Potential,
- Morphospace.
Bioelectricity: The Conductor of Biological Form
As we’ve explored throughout this series, *bioelectricity* – the patterns of voltage across cells and tissues – plays a crucial role in shaping living organisms. These bioelectric signals act as a kind of “software” that controls how the “hardware” (genes and proteins) is used, guiding development, regeneration, and other processes.
Manipulating bioelectric signals offers a powerful way to *control* biological form and function. It’s like rewriting the instructions that tell cells how to behave and how to organize themselves.
“Living Machines”: We’re Already Doing It (Sort Of)
In a sense, we’re *already* creating “artificial life” – or at least, “artificial living systems” – using bioelectricity. Consider these examples:
- Xenobots: These tiny, self-propelled “machines” are created from frog embryonic cells. They’re not genetically modified; their novel behaviors arise from rearranging the cells and exploiting their inherent self-organizing abilities.
- Anthrobots: Similar to xenobots, but made from *human* tracheal cells. These structures can move around and even promote the repair of damaged nerve tissue *in vitro*.
Scientists have been finding never-before-seen evidence, demonstrating that structure building can extend outside the usual expectations of biology, by creating Xenobots (frog skin tissues self-assembled), Anthrobots (human respiratory-tissue clusters that solves maze).
These are not “life” in the traditional sense – they’re not self-replicating organisms that evolve over generations. But they are *living systems* that exhibit novel, designed behaviors. They are “machines” built from biological components, and their behavior is, at least in part, controlled by bioelectricity. It represent an answer that the questions for a “created living form” is already here, not a far future vision – at least at early proof of concept.
Synthetic Biology: Designing Life from the Bottom Up and the Top Down
These “living machines” are examples of *synthetic biology* – a field that aims to design and construct new biological systems, often by combining engineering principles with biological components.
There are two main approaches to synthetic biology:
- Bottom-Up: Trying to build life from scratch, starting with individual molecules (like DNA and proteins) and assembling them into increasingly complex structures. This is an incredibly difficult approach, and we’re still in the very early stages.
- Top-Down: Taking existing biological systems (like cells) and modifying them, rearranging them, or controlling their communication to create new forms and functions. This is the approach used to create xenobots and anthrobots, and it’s proving to be much more feasible in the short term.
Dr. Levin, Dr. Bongard research teams demonstrate some evidence that existing systems exhibit those “unexpected structures/tissue formation”, a new method – going past gene, chemicals, bottom-up arrangement approach.
The “Anatomical Compiler”: Programming Biological Form
The long-term vision for this field is to develop something like an “Anatomical Compiler” – a system that can take a desired biological structure (e.g., a specific organ, a tissue with a particular function) and translate that into a set of bioelectric instructions that will guide cells to build it. Bioelectric and electrical studies suggest possible mechanism that goes past typical signaling (that is relatively limited) .
We aren’t putting together a detailed construction spec and order, much as building blocks. It means there exists top-down approach possible: much as one specifies, “grow new hand”.
This is still a distant goal, but research with xenobots, anthrobots, and other model systems is providing crucial insights into how bioelectricity controls biological form and how we can manipulate it.
Ethical Considerations: Playing with Life
The ability to create or manipulate life, even at this relatively simple level, raises profound ethical questions. Some considers the topic, if done too far, might be too dangerous:
- If we had achieved capabilities to build biological parts, tissues, structures (by bioelectric means, chemicals, or a future “compiler”) at industrial-scales and with extreme complexity/diversity (not the basic form of Xenobots now): what if they become harmful or a source of biological concerns.
- Synthetic minds/life has consciousness: Can newly “arranged” “artificial life” have the ability to “think”? Or to suffer? To “feel pain”? There is simply a lack of proper consciousness, feeling, understanding to define “awareness”. Dr. Levin talks and explains that there’s no real framework; science only shows how cells and system can be controlled and exhibit cognitive traits. The rest (pain, awareness) is unknown. It involves many unknowns.
- Unintended consequences. There are many scientists concerned and have ongoing discussions and talks at public levels (including with Dr Levin), that, by tinkering/experimentation:
- what are some other consequences. How do they evolve or react, what risk could potentially be.
- how to safeguard against runaway and “synthetic biology” creating possible existential/dangerous issues to life and earth’s existing creatures/planet.
We need to consider:
- Our Responsibilities: What are our responsibilities to these new forms of life, even if they are “artificial”? Do they have any moral standing?
- Potential Risks: What are the potential risks of creating or manipulating life? Could we accidentally create something harmful or dangerous?
- Unintended Consequences: Even if our intentions are good, could our interventions have unforeseen and negative consequences?
- Regulation:What type of framework to avoid potential disaster. How much monitoring, safeguarding do these new area of research, capabilities demand.
- Is-ought Even if science has knowledge and “how to”: how does, or can, this capability translate into responsible and correct next-steps (how ought we treat all entities).
These are complex questions with no easy answers. But it’s essential that we grapple with them as we move forward in this exciting and potentially transformative field.
There’s no simple “Neutral choice”. By acting, one changes new, emerging science trajectory (such as accidental sentience or artificial biology that can create “unintended problems”, e.g. defects). By doing nothing, that too involve crucial concerns – cancer, development, health will keep taking victims. Humanity is locked into this position of having great knowledge that goes past older expectations and discoveries (we can no longer “hide” from our own learning); one of these options will always lead to something and a type of outcome. Both Levin, other great thinkers continue discussions with philosophy communities on ideas/direction/ethics on what-ifs (what should, and could, guide best framework), not limited to biology and chemistry.
