Science News has a more balanced take, with additional quotes from peers.
> Some have also grumbled about Adamala’s efforts to draw attention to the work, which she says was rejected by Cell after one reviewer said SpudCells were not real biology. She then sent the 190-page manuscript to journalists, under embargo, even before she had uploaded it to the preprint server bioRxiv, where her colleagues could read and assess it. She says her group will submit it to a new journal soon. “It’s an unusual way of doing things,” says Kerstin Göpfrich, a synthetic biologist at Heidelberg University.
It would only be effective if the significance of this work is clear. They certainly felt this message needed to reach people, and that it did work makes it self evident they were probably right.
Journalists believing what you tell them says nothing about if the underlying work is actually significant.
The legacy of bad science being picked up is why this is a bad idea, even you personally don’t think it’s an issue the risk reward isn’t about just you.
My paper demonstrating a side channel attack on RSA via hyperthreading was rejected from the crypto preprint archive on the basis that it was "not cryptography".
(Reviewers at J.Crypto subsequently sat on it for a year and then suggested I submit it to a journal on CPU microarchitecture instead.)
Novel research is uniquely susceptible to "cool but it's not part of our field", because that critique is entirely correct until the research gets published!
our paper to a database venue about bringing GPU support to Presto was rejected. one of the reviewers wrote, and I quote verbatim: "the topic of the paper is too practical". I just couldn't help but laughed at it.
Exoplanets also aren't planets. Some things just seem to have definitions with a history that get applied to new discoveries that don't fall within the definition. Distinguishing random rocks in space from planets was done by requiring planets to orbit around the sun, and so planets elsewhere cannot be called planets no matter that it's 1:1 the same thing. Biology probably has a similar history of trying to draw a line somewhere between what was created and what evolved to be part of the 'natural' world
Exoplanets are planets. Also, for clarification, biology is not defined as “the study of things produced exclusively by natural evolution.” Synthetic biology works with biological components and living systems (DNA, proteins, regulatory networks, cells and organisms). It differs from much traditional biology mainly in its constructive, engineering-oriented approach. Synthetic systems are often built precisely to test hypotheses about how natural biological systems function. Claiming it is not biology is wrong IMO.
For anyone else that might be curios, the definition of a planet you will often see quoted online applies to bodies in our Solar System. It comes from the International Astronomical Union in 2006. This is the famous definition that dropped Pluto as a planet. While the criteria are widely quoted, that actual resolution isn't. The resolution:
The IAU...resolves that planets and other bodies, except satellites, in the Solar System be defined into three distinct categories in the following way:
(1) A planet [1] is a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, and (c) has cleared the neighbourhood around its orbit.
(2) A "dwarf planet" is a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape [2], (c) has not cleared the neighbourhood around its orbit, and (d) is not a satellite.
(3) All other objects [3], except satellites, orbiting the Sun shall be referred to collectively as "Small Solar System Bodies".
The definition here only applies to bodies in the Solar System.
Still a bad definition IMO. According to the definition if a catastrophic event were to occur that cluttered the neighborhood of a planet it would cease to be a planet until it was cleaned up. The definition of a planet should be based in the physical attributes of the celestial body itself, not in its role or relationship with other bodies. I'm a bit of an extremist on this front. Even our Moon would be a planet in my opinion. Seems silly when you think about our barren moon but there are for sure habitable moons out there. I can't imagine asking an alien "What planet are you from?" and them responding "erm, actually we are from a moon/planetary satellite".
What they meant when they said "planets" was the 8 (previously 9, previously to that 8, previously 7...) known and named planets in our own solar system. A hypothetical "Journal of Planets" that was actually about solar system astronomy wouldn't necessarily have known what to do with a new paper about 51 Pegasi b published 30 years ago. They're thinking "when we said planets, we actually always meant solar system planets, it just never came up until now".
The reviewer of this paper is saying that by biology they always meant naturally evolved cellular biology, not synthetic biology - there's just never been an example of the latter before.
I think the take is wrong, the receiving journals should be excited to expand their scope rather than frustratedly redefine their scope more narrowly, but definitions and categorization are hard.
Actually, that is the IAU stance. And their definition for exoplanet includes small, non-rounded objects orbiting stars which would be asteroids (or comets or whatever) if they happened to be around the Sun.
All that debacle around dwarf planets to prepare for future observations, and yet the distinction ceases to apply the moment you go outside the Oort cloud...
But really, that's just the naming systems being bad, obviously common people don't think asteroids around other stars are "exoplanets" or should be called that way
I'm not talking about edge cases like asteroids or planetoids or dwarf planets. I'm talking about actual planets. Like a gas giant orbiting a star. It's obviously a planet even if it's not orbiting Sol.
Not defending anyone but it's quite common for people to hold different definitions of words with some unknown presumed context in mind that others don't see in the moment. I'd argue it's the single biggest reason for all arguments in recent human history.
> for people to hold different definitions of words [...] is the single biggest reason for all arguments in recent human history.
IMO this extremely, extraordinarily true. And in my experience, it's somehow even more true for disagreements among scientists. Even though every scientific field is, in some sense, about defining a shared set of extremely precise jargon. (I recall two very well-respected scientists screaming at each other about the definition of "acidity" for instance)
That's fair, but rejecting a paper for that reason seems excessive to me. Even if the reviewer may think that synthetic biology is not biology, they would know that plenty of synthetic biology papers have been published in Cell.
It's frustrating because when trying to engage in intellectually curious dialog on HN sometimes people will attack my character and get upset because our perspectives seem to differ on the meaning of a specific word. When trying to reconcile the meaning sometimes people get upset and dismiss it as "that's just semantics". Semantics is the meaning of words... If our disagreement stems from differing opinions on what the word means how else can we reconcile or discuss the topic constructively?
The last time this happened I think the crux of the debate was the meaning of "unconstrained capitalism". Pretty sure the other person and I agreed on everything (values wise) except the precise meaning of that term, and the misunderstanding led them to accuse me of being unsavory.
These exchanges tend to discourage me from engaging in HN for a while.
Yeah, I have a hard time reconciling this especially since biology and biologic research often involves things like enzymes which both aren't alive and are synthetically created.
I'm certain cell magazine has published articles on novel enzyme discovery.
The problem is this: as an academic you tend to know the reviewer landscape within your field. You have seen this happen to a colleague before, they submitted a paper, it had interesting results - it was forcefully rejected by 1 or 2 extremely negative reviewers. The publication gets delayed, you need to wait another 6 months to get the next set of reviews. Meanwhile, some "colleague" from another lab publishes nearly identical experiments and gets slightly better results. They push onto a pre-pub server and immediately get it into a tier-1 venue. They are now state of the art. You are now merely the person reproducing original work.
My wife has had numerous papers rejected because the reviewer belonged to a competing lab. Took a few tries and a request to exclude a certain reviewer and hey presto! published!
Hard to say but my impression is that most academics are honest and would try not to do this, but also there are rivalries between labs and that tends to encourage "everything they do is bad and we're great" mentalities so it's definitely not surprising.
Yeah, the scientific review process is extremely weird. I've had several papers published and the responses you get from reviews is sometimes complete nonsense. Sometimes it feels like some reviewers do little more than skim your paper or get a power trip off of rejecting people. Lots of politics and people trying to reject ideas that are counter to the ones their own labs are pushing. I don't blame the authors for expecting to get push back from their work, many breakthroughs are usually met with resistance from the status quo.
“This was where the field had been stuck for some time. Researchers before Adamala had figured out different ways to feed and grow synthetic cells and to replicate their DNA. But cell division is a different beast. A typical cell reorganizes its cytoskeleton — a network of protein fibers that provide structural support — to halve its DNA and split. Synthetic biologists could not figure out how to get their cells to undergo this complex process.
So Adamala decided to ditch the cytoskeleton. One day, while tearing through the literature, she came across an interesting mechanism in a paper (opens a new tab). By attaching protein tags to a cell membrane, the synthetic biologist Reinhard Lipowsky (opens a new tab) at the Max Planck Institute of Colloids and Interfaces attracted other proteins to crowd around and physically bend the membrane, forcing the cell to divide. Following this approach, Adamala tweaked a cell-membrane protein and tested it in her protocells. After several tries, it worked.“
I interpreted it as the author adding some internal dialog about how they want to do more research on the article/person in question so they were opening up a new tab so they could learn more. But I can see how this could certainly be some copy/paste artifact.
You stumble upon a news article from 2226. You read it to see who, between Google, OpenAI and Anthropic, won the AI race.
Instead, your learn about Biotic.
It's now the leading polity in the solar system and its environs. It bought Alphabet, OpenAI and Anthropic in a single day back in 2084.
Humans are no longer desired. Their reproduction is capped to an optimal minimum assuring the survival of the species as a relic.
For productive matters, Biotec preferes to rely on its biomachines. Imagine drones giving birth to offspring when traffic is at a peak. It takes more energy, sure. But no factory, nor workers are needed.
If left alone, machines would multiply out of control, instead of rotting to waste like in the olden days.
Interesting thought experiment, but I don't see why automating machines that build and repair other machines wouldn't be sufficient. At the limit, such a machine would be able to repair itself, or repair other long-running machines. I imagine it would come down to wear and efficiency loss.
Manufacturing requires micromanaging every aspect of the process, requiring special machinery, trained workforce (human or not), inventory management.
Reproduction, once we master its blueprint of course, is much less demanding: just provide the ingredients at approximate proportions and the chemistry will work its magic to provide a similar enough unit to achieve the required task.
In this case I'm seeing 'micromanaging' as something akin to automating a Tesla superfactory: machines complete each individual step, we get a working car at the end.
Obviously, we'd have processes built that build machines for each of the individual tasks, or changing tracks to support new car models.
From my perspective, this framework of a factory could map to many other endeavours where we either produce the end product or a machine used for something else.
So, the difference would be whether the machines utilize chemical/biological processes for working, or are made out of steel, at which point it would boil down to economics.
I guess I don't see what's so special about adding 'bio' to these perpetual factories.
I'm not too well read so Mars Express is the first fiction where I came across these themes. Highly recommend. When I watched it 18 months ago I didn't realize real development was ongoing in these scifi-seeming fields
Interesting that this is led by the same Dr. Kate Adamala who ended the right-handed-proteins experiment a couple of years ago. Given how close she was I'm not surprised she's made this work.
the left handed life thing is the only thing that makes me wonder about Adamala's judgement... there zero plausible mechanism for left handed life to succesfully compete.
in case you didn't know, your immune system WILL detect left handed pathogens, possibly more aggressively, and two of the body's mechanisms for fighting infection -- fever and ozonolysis -- are distinctly achiral
Arguably we should push for mirror life for industrial purposes FASTER because biocontrol is easier (they got nothing to eat) and lab escape is far less likely
Perhaps they can eat some carbohidrates, all carbohidrates are chiral, but some bacterias may eat some of the unusual carbohidrates too. But amino acids are beyond any possibility, and fixating nitrogen is hard, so I also think they will starve to death very fast.
Back then, it sounded like making right-handed life was decades away. But with this work, couldn't you just as easily make this kind of synthetic cell right-handed?

It looks like this particular research is conducted at the University of Minnesota
Layman question. How can they determine that the cell divided in a reproducing/growing fashion rather than due to mechanical or other external means because of the methodology they used to trigger the act of breaking up? Or does it not matter in living cells either?
In eukaryotic cells (your cells) the cytoskeleton is needed to shape the cell, position DNA, and most importantly for this study, separate daughter cells allowing replication. Think of the complexity here, you need to make compartments to separate the copies of the genetic material, physically separated during division. Microtubules assemble the "mitotic spindle" and then pulls the sister chromatids apart from each other. After the chromosomes separate, other cytoskeletal filaments (actin and myosin) form a contractile ring, which tightens to create a cleavage furrow. The membrane pinches inward until the cell splits in two.
Bacteria work slightly differently, since they don't have a eukaryotic cytoskeleton, but they do have cytoskeletal-like proteins (FtsZ), since they divide by building the cell wall inward (I am not an expert on bacteria lol).
SpudCell doesn't have a cytoskeleton, so instead it relies on a physical membrane-rupture strategy. It makes membrane proteins from its own DNA (a-hemolysin), which inserts into the membrane. They help fuse with feeder liposomes for growth. For division, these proteins crowd on the membrane surface, creating mechanical stress which leads to membrane instability, which then splits on its own.
And the synthetic cell doesn't need to do anything about separating genetic material between daughter cells because it's just free-floating DNA that is likely to be in both parts. Right?
The complexity is certainly awesome, however there are all kinds of "free lunches" that we can take advantage of here, I'm paraphrasing (and glazing) Mike Levin here - when you work with biological systems, you are handling an agential material that naturally expresses itself.
I suspect that, once scientists lean more into the right kind of communication with these systems that many substantial leaps forward will be made. I am very excited about it too, mostly because I think it has the potential to positively impact how we see ourselves (humans) in the natural world.
Somewhere here is a science fiction story that humanity is too inexperienced at synthetic biology to create sophisticated forms for manufacturing and have to result to the equivalent of bashing proteins together to make inferior biology to some future humans or other species.
There are multiple FDA-approved lab-grown meats on the market. You can literally go to a handful of restaurants and order lab-grown meat today. The production process is just expensive and it's getting scaled out.
Lab-grown meat seems completely unrelated to synthetic biology. For lab grown meat the problem to my knowledge is that it is very expensive to grow vertebrate cells in the absence of an immune system because every contamination kills the batch.
Interesting. I pasted the article URL into Claude Opus 4.8, along with some questions about uses for cells that couldn't reproduce and Claude thought about it for a while, and then got murdered by the guardrails. I was invited to edit the question and try again; in a different chat. Or use a dumber model.
I suppose I can see why. But at the time I was just curious about the idea of "mule" cells.
I'm curious what you asked? I had Opus 4.8 ingest the URL and give me some ideas about what's possible and it eventually got to AI and self repairing/improving factories along with listing risks etc.
"The idea of a cell that didn't reproduce at all occurred to me. Maybe created by a factory cell. It would be used to change an environment or produce some useful compound. I can imagine manufacturing them to process chemicals, or create mechanical structures. Put a network address in each one and they can be coordinated. The advantage of not reproducing is that they couldn't mutate if they had no reproduction mechanism at all. Can only come from the factory. Of course they could still be susceptible to viruses."
I've done a little googling since, and mule cells are actually a thing. In organisms they are very common. Neurons are an example. Parts of the immune system. There's also a thing in bacteria where cells divide, creating two daughter cells, one that can reproduce and one that can't. The one that can't makes a support structure around the one that can and then dies. This is how sporulation works.
None of this is deep, dark secret stuff. Some clumsy Wikipedia research got me this deep. If that's dangerous we are in deep sh*t.
(I'm not a biologist, I'm an animator who makes visualizations for university courses.)
I vastly prefer the explanation like of Roadside Picnic. They didn't try to create us, they don't care that we're here, and, ultimately, we will never be able to know them in any meaningful sense. ;)
Or another take, life isn't all that special if we can make it this easily.
We have always theorized the start of life but this could actively show that life could have started on a rock floating in space given enough time. No sky daddy and no aliens necessary!
This is great, I assumed we were getting close (and not quite there), so it's great to see the progress. The path from here to building a single-celled organism out of nonlive materials looks very straight.
Scientists seem really busy these days creating synthetic life: advances in AI, human eggs from stem cells and now this - synthetic cells. I somehow feel they are inspired by the Alien movies.
> 'Unlike living natural cells... the synthetic SpudCell can't survive and replicate without feeding on external food and ribosomes'
So in the future when there's a lab leak from the Wuhan Institute of SpudCellular Biology, the SpudCells will devour all biological life they can in order to harvest the building blocks they need. "Just social distance and wear two masks," the Surgeon General tells the CNN correspondent, as he disolves to red gray goo on live TV.
This is so cool! I had once gone in the rabbit-hole of finding artificial life and there were experiments which did multiple phases but none which did the whole thing and I was left wondering why. I am a bit happy to see that someone was working on it (and succeeded!)
There is another submission on Hackernews which talks about: The first early human eggs from stem cells[0] which is an interesting discussion to read through on hackernews as well.
From cells dividing to human generation there is a single step.
Similarly a program that runs on a computer, where its only interactions are strings of numbers is the same as an entity having to interact with the world.
Interesting, we should be able to have LLMs generate full genetic code or Inpaint into existing code that can be installed into a cell as DNA and have it divide out into any custom creature.
We could launch these custom bacteria in stasis to planets around the galaxy and seed life everywhere.
Definitely. An implication of several strands of idealism is that we will be able to create artificial life (with consciousness)... it will just look like biology.
> “It’s a big step forward to this holy grail of making a living thing out of dead components,” said Sijbren Otto, a systems chemist at the Stratingh Institute for Chemistry in the Netherlands who was not involved in the work.
That is the holy grail? I get that the goal is to "grow" biofuels, plastic, fertilizer, drugs, or whatever else we can imagine. But is that worth the many apocalyptic sci-fi outcomes we can imagine?
Yes, mechanically constructing life would be absolutely stupendous for science. The real tragedy of modern sci-fi is that everyone read the books and decided it was reality.
“Penicillin?! A poison from fungus that kills living cells?! Haven’t you played the sci fi game The Last of Us?”
Stories are stories, man. Story-logic is biased towards interesting tales. And “discovery from the natural world turned to human aims with great results” is uninteresting because we do amazing things these days.
I don't spend any time on LW but perhaps that is because I'll have to face that all my ideas have already been explored more eloquently by him and the communities he's part of.
I think the issue is that those stories are rooted very much in the failures of human systems that we see every day. They are us imagining what could go wrong based on what has gone wrong and is going wrong.
It would be a lot easier to set those warnings aside if we didn't have so many examples of the very things they warn about happening in real life.
We currently have a system where private individuals can fund private science and then deploy the results globally to their own profit with very few mechanisms for enforcing restraint and caution. And we've seen this backfire with horrific consequences over and over again.
Lead in the gasoline. Microplastics in the water. Pesticides widely applied to the biosphere. In my area PCBs are a massive risk due to past soil contamination. In other areas fracking biproducts make the water undrinkable.
Hell the AI rush in the face of climate change. We literally have heatwaves killing massive numbers of people while a tiny handful of investors and the companies they control are drastically increasing our carbon emissions in the race for AI.
It's easy to imagine all the ways in which synthetic life could go horribly wrong, even with out those sci-fi stories, especially since all but the youngest of us have been through a brutal pandemic in living memory.
It's very, very hard to imagine our current system showing proper restraint with this technology.
It's important to emphasize that cars are the leading source of carbon emissions. Anyone fighting against AI on the basis of climate change should be fighting for safe and reliable alternatives to driving everywhere.
This is "whatabboutism" which is a logical fallacy.
Someone doesn't have to talk about the climate impacts of cars every time they talk about the climate impacts of AI. Both have climate impacts, independently of each other, and we should be dealing with the climate impacts of both simultaneously.
Regardless, don't assume the person you are talking to isn't consistent. Peruse my personal blog and you will see that I, in fact, ran a whole city council campaign on a platform of "to fight climate change we should not be driving".
Someone doesn't have to talk about the climate impacts of cars every time they talk about the climate impacts of AI.
Actually they do, because the best way to get cars off the road is to replace many if not most of their occupants with AI.
Private ownership of cars is not the problem. The assumption that people have to drive all over the place to get stuff done is the problem. Let's work on that.
> the best way to get cars off the road is to replace many if not most of their occupants with AI.
I'm so confused by this. Instead of one person driving a car to the store and parking, now the car is driving itself to the store with one person in it, dropping them off, and then either parking, or driving itself around more, back to the house or to a distant parking facility. In crowded cities, the car is just going to drive around the block empty for an hour instead of paying $12 for parking. Single-occupancy vehicles are a big problem now; I don't understand how introducing a bunch of zero-occupancy vehicles are an improvement on that? It seems very obvious to me self-driving cars are going to significantly increase the total number of miles driven every day in the world.
I didn't say anything about self-driving cars. You still need to go to the store, if you don't get your stuff delivered by someone who is (hopefully) delivering to more than one house.
You don't need to go to the office. Neither does your car.
That’s just wrong. Transportation is 24% of carbon emissions with 18% road transportation and about 10% of that from cars. Electricity and heat production is the largest source of carbon emissions.
> cars are the leading source of carbon emissions.
WTF? cars are less than 7% and even including trucks we are barely around 11%. when you look at greenhouse effect instead of "just carbon", the percentages are even tinier.
If you are looking for leading sources of climate change look at electricity/heat, industry and agriculture.
just because (bad) politicians are always talking about cars when talking about climate it doesn't mean the are actually a meaningful component. it is smoke and mirros…
And the most promising of those alternatives is, ironically enough, AI itself. Fighting data centers is literally like fighting nuclear power. If you just want more carbon emissions, then by all means, proceed.
Of course most people who commute to work don't need to be doing that now, but that's the other big elephant in the room with AI. We don't use the intelligence we already have, so what makes us think the emergence of ASI/AGI will change anything?
I'm not a biologist so I can't say for sure, but it seems like it would be a lot easier to edit an existing living organism to produce those products than it would be to create completely from scratch. We already do this with the process known as precision fermentation. We've gotten very good at editing genomes via CRISPR and related techniques and are only getting better
but those guys could probably add components to their cell to make it truly self-supporting although in biology there is a big difference between "barely works" and "high performance"
It seems that eventually you could build much more flexible and powerful if you build from scratch. Hacking existing cells is a shortcut but longer term we may get grey goo.
I don’t think biological cells are likely to lead to grey goo the way nanobots are - we may just end up with green and pink goo instead of animals and plants though.
At one end we're creating artificial life, the other we are creating artificial intelligence.
We're coming at everything we as the human race have known for millennia from both ends, simultaneously. We're recreating that, from scratch.
That is absolutely fucking wild.
Ironically this "holy" grail will end up being the thing that finally puts religious creation myths in their place (i.e. as bullshit) since we will be able to answer with 100% certainty that we are not alone or unique in the universe since we recreated life in the fucking petri dish so why not across the billions and trillions of other planets out there?
> we will be able to answer with 100% certainty that we are not alone or unique in the universe since we recreated life in the fucking petri dish
I don't think we are alone, but this is not logically sound. The conditions in the petri dish might be easily so special that their natural prevalence is < 1 per universe.
The first time this happens in a petri dish will likely have to be under extremely controlled circumstances. But the process will be modified and toyed with once it exists and I think that this will eventually lead to whole spectrum of (quasi?)biological systems that together cover a broad range of environmental conditions.
> Ironically this "holy" grail will end up being the thing that finally puts religious creation myths in their place (i.e. as bullshit) since we will be able to answer with 100% certainty that we are not alone or unique in the universe since we recreated life in the fucking petri dish so why not across the billions and trillions of other planets out there?
You if believe creating life will end religion then you're wrong.
We thought evolutionary theory would do the same, now we got people who believe god directed evolution. Some believe everything evolved from a common ancestor except Humans.
So the believers will adapt to believe that Genesis was talking about exactly this.
> Who thought evolutionary theory would end religion?
Some terribly ill-informed people have. Plus ca change. Sadly, the experience of "Christianity" of many Americans is either caricature or some kind of novel and vulgar fundamentalism they grew up around that sprouted on American soil in the last century or two. Add to that the black legends supplied by the Enlightenment and others and you have a perfect storm of malicious ignorance.
Science can't disprove religion. Consider the "big bang", is that any less of a miracle than "God did it"? Science is like "just give us one miracle and we'll explain the rest".
The big bang theory isn't even incompatible with the idea that 'God did it'; the idea was first proposed by a Catholic priest, as a matter of fact! I think the anti-science stance of evangelicals has eclipsed in the modern consciousness the fact that modern science owes much to the Catholic church.
> This startling idea first appeared in scientific form in 1931, in a paper by Georges Lemaître, a Belgian cosmologist and Catholic priest.
That depends on which religion, doesn't it. The categorical claim doesn't make any sense, because the general notion of "religion" doesn't entail anything that is inherently at odds with science. And if there is a normative sense of what is or isn't religion, then this is even more true, because normativity means there is a correct religion or most correct religion, and you can't be correct without being true.
Some religious traditions, however, do make claims that are wide open to scientific discreditation (like the "Lamanite hypothesis" of Mormonism).
I think this is really the wrong framing. Science can't disprove religion. The question is whether it makes any sense to believe in the religion in the first place, given what observation and science say about the universe. Science can't prove that God didn't create the universe a nano-second ago in exactly the state to produce this temporal evolution, but no one believes that because its not explanatory and also fails a bunch of other, not-necessarily scientific, but rationally motivated epistemological tests.
The way I see this is that science cannot disprove any particular religion, but it can probably offer more compelling explanations for the state of the world than religion can offer. People haven't flocked away from religion because explanations for the state of the world aren't really what people want from religion. They want a sop for their anxieties. they want community, etc. I think believing in nonsense is a real shitty way to get these things, but I'm not most people.
(Disclaimer: on religion I try to be respectful, as an agnostic atheist) I do think our ability to “build tools that create life” is incredible, but to me has a limited argumentative impact on what I guess you could call the “prime mover” question: _But how did everything start?_ Does that seem reasonable or am I downplaying the implications you mentioned?
Thomas Aquinas made the argument that all life comes from other life in the 13th Century. I wouldn't classify it as a modern pivot so much as one of the central philosophical arguments for the existence of a Creator.
Not really. AI isn't intelligent by any stretch. To make that claims requires ignorance of what constitutes "intelligence", especially the most essential element of intelligence, viz., intensionality. LLMs or expert system or whatever absolutely lack intensionality by definition because computation is by definition a purely syntactic process.
> Ironically this "holy" grail will end up being the thing that finally puts religious creation myths in their place
I think you're way out of your depth here and making things up. The first tell is that you use "religion" as a blanket term as if all religious traditions make the same claims, which they absolutely do not. You can discredit, say, Mormonism much more easily than, say, Islam (though, ironically, there is a strange structural similarity between the two).
> we will be able to answer with 100% certainty that we are not alone or unique in the universe since we recreated life [..] so why not across the billions and trillions of other planets out there?
Who exactly claims that human beings or, generally, life on earth is the only life in the universe? None of the major religions do. I'm also going to assume that Christianity (or some caricature of it) is for you the paradigmatic reference point of what constitutes "religion", in which case there is nothing in Christian theology that excludes the possibility of life - even embodied intelligent life - elsewhere in the universe. (The latter is actually interesting from an ontological perspective. If the definition of "human" is "rational animal", then by definition, all rational animals are human. So, from an ontological perspective, even if an intelligent, phylogenetically distinct species were to be found on another planet, ontologically, they would also be human.)
While this is an impressive step forward, there remains an extremely long way, probably of several decades, until being able to design and synthesize a cell comparable in complexity with a bacterium.
The thing that they made is more alive than a crystal, which when placed in a suitable solution will grow and reproduce its own structure, but much less alive than even the simplest known living cells.
Its "life" is similar to that of a brain-dead human, whose body is not left to die by a bunch of machines that pump air into its lungs and nutrients through its blood vessels.
The techniques developed to make this pseudo-cell might evolve eventually into techniques able to make a true cell and it is likely that valuable information can be extracted from experiments with it, but it is very unlikely that any of the ancestors of the living beings has ever had even a remote resemblance with this (because it is far too dependent on continuously receiving complex cellular components and nutrients from outside; simplified parasitic living beings could appear only when there already existed sufficiently complex living hosts for the parasites).
Some components of this thing are growing by reproducing themselves, but like I have said, so does any crystal, thus it is difficult to choose a criterion that will distinguish with certainty what is living from what is non-living.
The growth is followed by a kind of division into 2 vesicles, but that happens by a mechanism very different from any living cell. Many inorganic things will split when growing over a certain size, so again it is hard to decide whether this can be called living.
> Its "life" is similar to that of a brain-dead human, whose body is not left to die by a bunch of machines that pump air into its lungs and nutrients through its blood vessels
A brain-dead human is alive, but just facing systemic collapse, aka death. That's not to imply that what the scientists here have created is alive, but the comparison isn't so apt.
As a multi-cellular organism, a brain-dead human is not alive, even if most of its cells may remain alive as long as they are fed from outside.
OK, what I have said above is not generally true, as some brain-dead humans may be more alive than others, e.g. some integrative functions, like some feedback loops that function through the endocrine system or through the autonomous nervous system, may still be working, connecting some organs with each other.
My comparison was with a very dead brain-dead human, who was reduced to the equivalent of a tissue culture.
These artificial cells also have some components that continue to work like in a living cell, doing some nucleic acid replication and some protein and lipid synthesis from precursors provided from outside, but they lack the capability to perform many of the chemical reactions that would be needed to close the complex network of feedback loops that enable a true living cell to live autonomously.
If you can disassemble and reassemble a thing, you can say you understand it. Not perfectly. But understand it. I’d imagine properly understanding rudimentary cellular biology will come with perks.
(Also, does the Holy Grail imply both a boon and a cost? Or is that just Indian Jones.)
I think one useful application of this would be life built on stuff that doesn't interact with our cells - artifical bases, nucleotides and all. Then we could have non-biological self-replicating robots
Yeah, imagine if one day it will become trivial to blow up the world. Enough people hate humanity that they would do it, by tomorrow if they could. Seems like out exponential growth in technology will eventually lead up to that. If not actual nuclear explosion, then biological weapons. Would we need to enslave humans not to do it. How would that work.
I agree with your conclusion. We start by enslaving certain classes of humans like Peter Thiel or Elon Musk. Anyone with more than $1B gets the collar. Populism is a helluva drug.
> Some have also grumbled about Adamala’s efforts to draw attention to the work, which she says was rejected by Cell after one reviewer said SpudCells were not real biology. She then sent the 190-page manuscript to journalists, under embargo, even before she had uploaded it to the preprint server bioRxiv, where her colleagues could read and assess it. She says her group will submit it to a new journal soon. “It’s an unusual way of doing things,” says Kerstin Göpfrich, a synthetic biologist at Heidelberg University.
https://www.science.org/content/article/lab-created-spudcell...
That's being kind; it's a complete overreaction, simply put.
Uploading the manuscript to a preprint server and/or submitting to another journal, which Adamala is doing/planning to do, is the normal response.
Sending it to journalists beforehand is what I consider an overreaction.
The legacy of bad science being picked up is why this is a bad idea, even you personally don’t think it’s an issue the risk reward isn’t about just you.
(Reviewers at J.Crypto subsequently sat on it for a year and then suggested I submit it to a journal on CPU microarchitecture instead.)
Novel research is uniquely susceptible to "cool but it's not part of our field", because that critique is entirely correct until the research gets published!
The IAU...resolves that planets and other bodies, except satellites, in the Solar System be defined into three distinct categories in the following way:
(1) A planet [1] is a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, and (c) has cleared the neighbourhood around its orbit.
(2) A "dwarf planet" is a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape [2], (c) has not cleared the neighbourhood around its orbit, and (d) is not a satellite.
(3) All other objects [3], except satellites, orbiting the Sun shall be referred to collectively as "Small Solar System Bodies".
The definition here only applies to bodies in the Solar System.
Still a bad definition IMO. According to the definition if a catastrophic event were to occur that cluttered the neighborhood of a planet it would cease to be a planet until it was cleaned up. The definition of a planet should be based in the physical attributes of the celestial body itself, not in its role or relationship with other bodies. I'm a bit of an extremist on this front. Even our Moon would be a planet in my opinion. Seems silly when you think about our barren moon but there are for sure habitable moons out there. I can't imagine asking an alien "What planet are you from?" and them responding "erm, actually we are from a moon/planetary satellite".
<<insert nerd screeching about the word planet>>
Bizarre argument.
Imagine writing this.
The reviewer of this paper is saying that by biology they always meant naturally evolved cellular biology, not synthetic biology - there's just never been an example of the latter before.
I think the take is wrong, the receiving journals should be excited to expand their scope rather than frustratedly redefine their scope more narrowly, but definitions and categorization are hard.
All that debacle around dwarf planets to prepare for future observations, and yet the distinction ceases to apply the moment you go outside the Oort cloud...
But really, that's just the naming systems being bad, obviously common people don't think asteroids around other stars are "exoplanets" or should be called that way
https://en.wikipedia.org/wiki/WISE_0855%E2%88%920714
IMO this extremely, extraordinarily true. And in my experience, it's somehow even more true for disagreements among scientists. Even though every scientific field is, in some sense, about defining a shared set of extremely precise jargon. (I recall two very well-respected scientists screaming at each other about the definition of "acidity" for instance)
It's frustrating because when trying to engage in intellectually curious dialog on HN sometimes people will attack my character and get upset because our perspectives seem to differ on the meaning of a specific word. When trying to reconcile the meaning sometimes people get upset and dismiss it as "that's just semantics". Semantics is the meaning of words... If our disagreement stems from differing opinions on what the word means how else can we reconcile or discuss the topic constructively?
The last time this happened I think the crux of the debate was the meaning of "unconstrained capitalism". Pretty sure the other person and I agreed on everything (values wise) except the precise meaning of that term, and the misunderstanding led them to accuse me of being unsavory.
These exchanges tend to discourage me from engaging in HN for a while.
Yeah, I have a hard time reconciling this especially since biology and biologic research often involves things like enzymes which both aren't alive and are synthetically created.
I'm certain cell magazine has published articles on novel enzyme discovery.
TL;DR politics breaks everything.
I've done that once in an anonymous chat group with about 35 people in it.
So Adamala decided to ditch the cytoskeleton. One day, while tearing through the literature, she came across an interesting mechanism in a paper (opens a new tab). By attaching protein tags to a cell membrane, the synthetic biologist Reinhard Lipowsky (opens a new tab) at the Max Planck Institute of Colloids and Interfaces attracted other proteins to crowd around and physically bend the membrane, forcing the cell to divide. Following this approach, Adamala tweaked a cell-membrane protein and tested it in her protocells. After several tries, it worked.“
This is the novel bit.
It’s this. I noticed after posting, found it funny and so left it in.
From my point of view: a team combined all the tricks in the community into one machine and we finally created a new life form to play with!
Instead, your learn about Biotic.
It's now the leading polity in the solar system and its environs. It bought Alphabet, OpenAI and Anthropic in a single day back in 2084.
Humans are no longer desired. Their reproduction is capped to an optimal minimum assuring the survival of the species as a relic.
For productive matters, Biotec preferes to rely on its biomachines. Imagine drones giving birth to offspring when traffic is at a peak. It takes more energy, sure. But no factory, nor workers are needed.
If left alone, machines would multiply out of control, instead of rotting to waste like in the olden days.
Reproduction, once we master its blueprint of course, is much less demanding: just provide the ingredients at approximate proportions and the chemistry will work its magic to provide a similar enough unit to achieve the required task.
Obviously, we'd have processes built that build machines for each of the individual tasks, or changing tracks to support new car models.
From my perspective, this framework of a factory could map to many other endeavours where we either produce the end product or a machine used for something else.
So, the difference would be whether the machines utilize chemical/biological processes for working, or are made out of steel, at which point it would boil down to economics.
I guess I don't see what's so special about adding 'bio' to these perpetual factories.
And yes, science it seems is advancing faster than we might be aware of.
in case you didn't know, your immune system WILL detect left handed pathogens, possibly more aggressively, and two of the body's mechanisms for fighting infection -- fever and ozonolysis -- are distinctly achiral
Arguably we should push for mirror life for industrial purposes FASTER because biocontrol is easier (they got nothing to eat) and lab escape is far less likely
> (they got nothing to eat)
They can eat fat that are not chiral.
Perhaps they can eat some carbohidrates, all carbohidrates are chiral, but some bacterias may eat some of the unusual carbohidrates too. But amino acids are beyond any possibility, and fixating nitrogen is hard, so I also think they will starve to death very fast.

It looks like this particular research is conducted at the University of Minnesota
In eukaryotic cells (your cells) the cytoskeleton is needed to shape the cell, position DNA, and most importantly for this study, separate daughter cells allowing replication. Think of the complexity here, you need to make compartments to separate the copies of the genetic material, physically separated during division. Microtubules assemble the "mitotic spindle" and then pulls the sister chromatids apart from each other. After the chromosomes separate, other cytoskeletal filaments (actin and myosin) form a contractile ring, which tightens to create a cleavage furrow. The membrane pinches inward until the cell splits in two.
Bacteria work slightly differently, since they don't have a eukaryotic cytoskeleton, but they do have cytoskeletal-like proteins (FtsZ), since they divide by building the cell wall inward (I am not an expert on bacteria lol).
SpudCell doesn't have a cytoskeleton, so instead it relies on a physical membrane-rupture strategy. It makes membrane proteins from its own DNA (a-hemolysin), which inserts into the membrane. They help fuse with feeder liposomes for growth. For division, these proteins crowd on the membrane surface, creating mechanical stress which leads to membrane instability, which then splits on its own.
I suspect that, once scientists lean more into the right kind of communication with these systems that many substantial leaps forward will be made. I am very excited about it too, mostly because I think it has the potential to positively impact how we see ourselves (humans) in the natural world.
(not just grumpy because that's what I did my PhD research on)
Out of curiosity, do you use Claude a lot and did you pick up the saying from it?
Are you Claude?
Or just a coincidence?
I suppose I can see why. But at the time I was just curious about the idea of "mule" cells.
"The idea of a cell that didn't reproduce at all occurred to me. Maybe created by a factory cell. It would be used to change an environment or produce some useful compound. I can imagine manufacturing them to process chemicals, or create mechanical structures. Put a network address in each one and they can be coordinated. The advantage of not reproducing is that they couldn't mutate if they had no reproduction mechanism at all. Can only come from the factory. Of course they could still be susceptible to viruses."
I've done a little googling since, and mule cells are actually a thing. In organisms they are very common. Neurons are an example. Parts of the immune system. There's also a thing in bacteria where cells divide, creating two daughter cells, one that can reproduce and one that can't. The one that can't makes a support structure around the one that can and then dies. This is how sporulation works.
None of this is deep, dark secret stuff. Some clumsy Wikipedia research got me this deep. If that's dangerous we are in deep sh*t.
(I'm not a biologist, I'm an animator who makes visualizations for university courses.)
Also, go MN!
Or like a grad student didn’t dispose of their work properly and are desperately trying to distract from their scandal.
We have always theorized the start of life but this could actively show that life could have started on a rock floating in space given enough time. No sky daddy and no aliens necessary!
So in the future when there's a lab leak from the Wuhan Institute of SpudCellular Biology, the SpudCells will devour all biological life they can in order to harvest the building blocks they need. "Just social distance and wear two masks," the Surgeon General tells the CNN correspondent, as he disolves to red gray goo on live TV.

Similarly a program that runs on a computer, where its only interactions are strings of numbers is the same as an entity having to interact with the world.
We could launch these custom bacteria in stasis to planets around the galaxy and seed life everywhere.

That is the holy grail? I get that the goal is to "grow" biofuels, plastic, fertilizer, drugs, or whatever else we can imagine. But is that worth the many apocalyptic sci-fi outcomes we can imagine?

Thank you for sharing your site as well :)
It would be a lot easier to set those warnings aside if we didn't have so many examples of the very things they warn about happening in real life.
We currently have a system where private individuals can fund private science and then deploy the results globally to their own profit with very few mechanisms for enforcing restraint and caution. And we've seen this backfire with horrific consequences over and over again.
Lead in the gasoline. Microplastics in the water. Pesticides widely applied to the biosphere. In my area PCBs are a massive risk due to past soil contamination. In other areas fracking biproducts make the water undrinkable.
Hell the AI rush in the face of climate change. We literally have heatwaves killing massive numbers of people while a tiny handful of investors and the companies they control are drastically increasing our carbon emissions in the race for AI.
It's easy to imagine all the ways in which synthetic life could go horribly wrong, even with out those sci-fi stories, especially since all but the youngest of us have been through a brutal pandemic in living memory.
It's very, very hard to imagine our current system showing proper restraint with this technology.
Someone doesn't have to talk about the climate impacts of cars every time they talk about the climate impacts of AI. Both have climate impacts, independently of each other, and we should be dealing with the climate impacts of both simultaneously.
Regardless, don't assume the person you are talking to isn't consistent. Peruse my personal blog and you will see that I, in fact, ran a whole city council campaign on a platform of "to fight climate change we should not be driving".
Actually they do, because the best way to get cars off the road is to replace many if not most of their occupants with AI.
Private ownership of cars is not the problem. The assumption that people have to drive all over the place to get stuff done is the problem. Let's work on that.
I'm so confused by this. Instead of one person driving a car to the store and parking, now the car is driving itself to the store with one person in it, dropping them off, and then either parking, or driving itself around more, back to the house or to a distant parking facility. In crowded cities, the car is just going to drive around the block empty for an hour instead of paying $12 for parking. Single-occupancy vehicles are a big problem now; I don't understand how introducing a bunch of zero-occupancy vehicles are an improvement on that? It seems very obvious to me self-driving cars are going to significantly increase the total number of miles driven every day in the world.
You don't need to go to the office. Neither does your car.
WTF? cars are less than 7% and even including trucks we are barely around 11%. when you look at greenhouse effect instead of "just carbon", the percentages are even tinier.
If you are looking for leading sources of climate change look at electricity/heat, industry and agriculture.
just because (bad) politicians are always talking about cars when talking about climate it doesn't mean the are actually a meaningful component. it is smoke and mirros…
Of course most people who commute to work don't need to be doing that now, but that's the other big elephant in the room with AI. We don't use the intelligence we already have, so what makes us think the emergence of ASI/AGI will change anything?
Its really easy now to engineer novel deadly viruses thanks to alphafold3

Natural life tends to evolve, which may have consequences for production.
For example, quorn production has to be restarted from a seed population after ~1000 hours because it tends to evolve colonial variants that break the product standards: https://www.davidmoore.org.uk/21st_century_guidebook_to_fung...
Their "minimal" cell is not quite a minimum product because it depends on prebuilt ribosomes and can't reproduce on it's own. No danger of gray goo!
This is more like it
https://www.jcvi.org/research/first-minimal-synthetic-bacter...
but those guys could probably add components to their cell to make it truly self-supporting although in biology there is a big difference between "barely works" and "high performance"
At one end we're creating artificial life, the other we are creating artificial intelligence.
We're coming at everything we as the human race have known for millennia from both ends, simultaneously. We're recreating that, from scratch.
That is absolutely fucking wild.
Ironically this "holy" grail will end up being the thing that finally puts religious creation myths in their place (i.e. as bullshit) since we will be able to answer with 100% certainty that we are not alone or unique in the universe since we recreated life in the fucking petri dish so why not across the billions and trillions of other planets out there?
What a time to be alive.
I don't think we are alone, but this is not logically sound. The conditions in the petri dish might be easily so special that their natural prevalence is < 1 per universe.
How does it affect religious ideas per se? its something many religious people long to find https://www.theatlantic.com/culture/2026/06/disclosure-day-a...
We thought evolutionary theory would do the same, now we got people who believe god directed evolution. Some believe everything evolved from a common ancestor except Humans.
So the believers will adapt to believe that Genesis was talking about exactly this.
Mainstream Christianity was not biblical literalist anyway. Read what Augustine or Origen had to say about interpreting Genesis.
Some terribly ill-informed people have. Plus ca change. Sadly, the experience of "Christianity" of many Americans is either caricature or some kind of novel and vulgar fundamentalism they grew up around that sprouted on American soil in the last century or two. Add to that the black legends supplied by the Enlightenment and others and you have a perfect storm of malicious ignorance.
> This startling idea first appeared in scientific form in 1931, in a paper by Georges Lemaître, a Belgian cosmologist and Catholic priest.
excerpt from https://www.amnh.org/learn-teach/curriculum-collections/cosm...
That depends on which religion, doesn't it. The categorical claim doesn't make any sense, because the general notion of "religion" doesn't entail anything that is inherently at odds with science. And if there is a normative sense of what is or isn't religion, then this is even more true, because normativity means there is a correct religion or most correct religion, and you can't be correct without being true.
Some religious traditions, however, do make claims that are wide open to scientific discreditation (like the "Lamanite hypothesis" of Mormonism).
The way I see this is that science cannot disprove any particular religion, but it can probably offer more compelling explanations for the state of the world than religion can offer. People haven't flocked away from religion because explanations for the state of the world aren't really what people want from religion. They want a sop for their anxieties. they want community, etc. I think believing in nonsense is a real shitty way to get these things, but I'm not most people.
You can’t win
I’m no 7 day creationist but haha my guy…
> Ironically this "holy" grail will end up being the thing that finally puts religious creation myths in their place
I think you're way out of your depth here and making things up. The first tell is that you use "religion" as a blanket term as if all religious traditions make the same claims, which they absolutely do not. You can discredit, say, Mormonism much more easily than, say, Islam (though, ironically, there is a strange structural similarity between the two).
> we will be able to answer with 100% certainty that we are not alone or unique in the universe since we recreated life [..] so why not across the billions and trillions of other planets out there?
Who exactly claims that human beings or, generally, life on earth is the only life in the universe? None of the major religions do. I'm also going to assume that Christianity (or some caricature of it) is for you the paradigmatic reference point of what constitutes "religion", in which case there is nothing in Christian theology that excludes the possibility of life - even embodied intelligent life - elsewhere in the universe. (The latter is actually interesting from an ontological perspective. If the definition of "human" is "rational animal", then by definition, all rational animals are human. So, from an ontological perspective, even if an intelligent, phylogenetically distinct species were to be found on another planet, ontologically, they would also be human.)
Kurzweil puts it between 2029-2032 and that seems right to me
https://en.wikipedia.org/wiki/Technological_singularity
The thing that they made is more alive than a crystal, which when placed in a suitable solution will grow and reproduce its own structure, but much less alive than even the simplest known living cells.
Its "life" is similar to that of a brain-dead human, whose body is not left to die by a bunch of machines that pump air into its lungs and nutrients through its blood vessels.
The techniques developed to make this pseudo-cell might evolve eventually into techniques able to make a true cell and it is likely that valuable information can be extracted from experiments with it, but it is very unlikely that any of the ancestors of the living beings has ever had even a remote resemblance with this (because it is far too dependent on continuously receiving complex cellular components and nutrients from outside; simplified parasitic living beings could appear only when there already existed sufficiently complex living hosts for the parasites).
Some components of this thing are growing by reproducing themselves, but like I have said, so does any crystal, thus it is difficult to choose a criterion that will distinguish with certainty what is living from what is non-living.
The growth is followed by a kind of division into 2 vesicles, but that happens by a mechanism very different from any living cell. Many inorganic things will split when growing over a certain size, so again it is hard to decide whether this can be called living.

(Also, does the Holy Grail imply both a boon and a cost? Or is that just Indian Jones.)
Custom metabolic pathways to manufacture materials could be more easily implemented with cells that are fully synthetic.
If the entire cell is synthetic its more easy to simulate it's full behavior and then it's faster to iterate on it during development.
Anytime you do something interesting or useful someone accuses you of trying to build the apocalypse.
