Fun fact: this microbe has Deinococcus radiodurans DNA in it and has been evolved over a trillion total cell divisions in Mars nutrients. Now it can grow and make lots of bioplastics from 100% Mars atoms!
Today, Pioneer Labs is announcing our first step towards terraforming Mars. 🚀🌼 With equipment that fits in just a single rocket launch, we can convert Martian dirt, water, and air into enough building materials to construct a small city on Mars. To do it, we made the first microbe for Mars. We found the best microbe on Earth and used evolution to teach it how to source all of its nutrients directly from Martian materials. The first astronauts will be greeted with safe shelter already filled with water, oxygen, and rocket fuel for the return journey. This is the first step toward using biology to make Mars a friendly place for life. It lets us live off the land and helps us build the next great frontier. It's the first of five organisms we need to green Mars ⬇️

Learn more about making the first microbe for Mars in our @AsimovPress podcast with @NikoMcCarty
Breaking: @Pioneer__Labs has engineered a microbe able to live on Mars, consuming solely nutrients found on the planet to create building materials. I interviewed @erika_alden_d, the CEO, to learn how they did it and what might come next. Much of the interview was about bottlenecks to growing life on Mars; the planet has tons of water, but only in the form of ice. (If you melted all that ice, it would create an ocean 100 feet deep across the entire planet!) Similarly, we talked about the dirt. Martian regolith has salts, heavy metals, and perchlorates that are toxic to many organisms. Some microbes on Earth are able to break down these toxins, though, so Pioneer is engineering them to make them better at eating those toxins while adding nutrients back into the soil. This could possibly help support plant life in the future.

Replying to @Pioneer__Labs
@Pioneer__Labs, a nonprofit in California, has made a microbe for Mars. They used rover data to: i) Figure out what is in the dirt on Mars; ii) Recreate that dirt here on Earth (toxins and all); iii) Culture Earth microbes in the dirt to find species that could grow.
Replying to @erika_alden_d
The first microbe for Mars is a safe, useful first step toward terraforming. Read the announcement from @Pioneer__Labs, including links to three new papers: blog.pioneer-labs.org/p/anno…

Life updates: @AsimovPress is officially back, with a renewed focus on original reporting and arguments in biotechnology. Also, we'll be helping (some) scientists launch philanthropic funds around the ideas published in the magazine with @RenPhilanthropy. More on this soon!
It's official: We're back! Asimov Press is returning with a sharper focus on intensive reporting in biotechnology. We're also working with @RenPhilanthropy to build our ideas in the real world. See more: press.asimov.com/articles/ba…

Come join us to do use robotics to fuse genomes together to survive Mars! We build Mars simulation chambers and design Mars greenhouses! This is a junior role - best suited for somebody looking to get into astrobiology and learn a lot across a lot of different subject areas.
We're looking to add a junior team member to help engineer microbes for Mars. You'd run evolution and functional genomics experiments in non-model microbes. Full-time, in person in Emeryville, CA. We review applications as they arrive. Priority deadline August 26; applications close September 15.

Our co-founder Devon Stork is giving a talk at the @exploratorium about our recipe to simulate Martian soil in the lab, and what we've grown in it so far! Get tickets to After Dark this Thursday, July 30, for the 8:30 pm talk - exploratorium.edu/visit/cale…

The Chory Lab is going to be hiring very soon for someone to work on this, please DM me if you are interested in working on a high impact open source lab automation platform, we are working on scaling a community of users and developers as we build out this platform. RTs appreciated 🙏
Using claude code to directly control a liquid handling robot is such a crazy experience

99% of what people know about terraforming Mars comes from the Red Mars trilogy and the board game 🤣 Check out this cool web game that incorporates the real + latest science! 🚀 nature.com/immersive/d41586-…

To engineer microbes for Mars, we needed to figure out exactly what chemistry they’d need to handle. So we talked to all the NASA people and read all the rover papers to figure out the recipe. This is science’s best guess for what Mars dirt + water is, and we grew stuff in it!
How do we simulate Mars here on Earth? We scrutinized Mars rover data so you don’t have to. 😛 Here’s what it tells us about how to simulate Mars on Earth, and which organisms could grow on Mars! 📄 Report: biorxiv.org/content/10.64898…

I thought people were joking about how aggressive the Fable safety filter is and manipulating context to make it seem worse than it is. But damn, I was wrong. My work account gets flagged on every single prompt. My personal one doesn't, but that's mostly for writing, not science.

Every time there's a Claude outage, I wonder if it's because the recursive bootstrapping has begun and all of the compute is going to make the AGI instead of summarizing papers for me.

13 years ago, I read a paper that changed how I think about science. No new experiments, just decades of scattered findings reasoned into one answer to "why are bacteria different from eukaryotes?" My breakdown of Julie Theriot's masterclass: devonstork.com/p/a-demonstra…

Plz stop asking me how to restart Mars’s magnetic field we DONT NEED IT
Terraforming Mars is a hard problem. You need to warm the entire planet by tens of degrees and make enough oxygen for humans to breathe. But you don’t need to create a magnetic field to live outside on a terraformed Mars.

I think the first successful virtual cells are going to model prokaryotes, not eukaryotes. It’s technologies like BioBloom that are going to be the difference between being able to collect enough data and NOT. Thoughts? @ChanZuckerberg @DBBurkhardt @arcinstitute @joncalles
This tube is a library of bacteria with every single-base-pair genome mutation, all DNA-barcoded.🧪Growth + barcode sequencing = data on millions of mutations. 📄 Report: biorxiv.org/content/10.64898… Retweet if you want more data, and read on if you want to use the library! 🧵

When you evolve bacteria, you get a random smattering of mutations. Now, you can measure fitness for every possible SNP mutation in the genome with a single experiment! BioBloom Libraries available on Addgene now! 🧪👇

Automation software is not written in normal languages, and you lose a lot of features because of that! There's really no reason for it either, other than vendors being able to lock you in. So we use @pylabrobot.
Most lab automation software is proprietary, expensive, and painful for anybody who codes, so we ditched it. Our liquid handler runs on Python + PyLabRobot, and we're sharing our protocols open-source.

We spent months thinking about atmosphere models and climate calculations for a habitable Mars. We did not, until now, consider the maximum acceptable arthropod dimensions. 🦟
