For ANME enthusiasts & for those who wonder how a methanogen turns into a methanotroph 👇New work by Orphanlab Identification of key steps in the evolution of anaerobic methanotrophy in Candidatus Methanovorans (ANME-3) archaea www.science.org/doi/10.1126/... @caltech.edu @mblscience.bsky.social

Been analyzing vacuña bone, tooth (left) and collagen (right) for C/N/O isotopes this week at IsoCamp! @isocampunm.bsky.social

A day to remember: #PBS visited our lab to film a documentary on life's history. We explored everything, microbes, ancient rocks and engineered plants & more! So grateful and lucky to share what we learn and love. Huge thanks to @uwbact.bsky.social & @uwmadison.bsky.social community for the support!

🚨New preprint! Origins of life research is fragmented across disciplines. We built #ChemOrigins, a community curated, searchable database of experimental prebiotic chemistry. Read: www.biorxiv.org/content/10.1... ➡️ chemorigins.bact.wisc.edu For feedback, contact: @brunocuevaszuviria.bsky.social

How did life begin, and why does it matter today? Proud to be one of the organizers of a new @asm.org report supported by the Moore Foundation, exploring the origins of microbes & how understanding it can shape breakthroughs in biotech, climate, and the search for life. ➡️ asm.org/reports/earl...

Accomplishment of the week! Let's go!!! @hollyrucker.bsky.social

Added some amazing prints by @drlperezdiaz.bsky.social to the lab!

🤩 Beautiful video capturing Hypothesis Fund Awardee @betulland.bsky.social's research on Earth's ancient microbes! We're a proud early supporter of this pioneering research, and can't wait to see what Betül discovers next! 💫

Excited to share a new Big Think + John Templeton Foundation interview featuring work from our lab: “Meet the survivors of Earth’s worst days.” Leading thinkers unpack how life persisted through catastrophe. @bigthink.com Watch here → bigthink.com/the-well/ear...

Had my third year committee meeting yesterday (went great!) so I made a cannoli bundt cake to celebrate 🍰 not the best photos but it tasted amazing

The Simons Graduate Fellowship in Ecology & Evolution is a great opportunity to pursue a PhD in our lab (sobollab.wp.txstate.edu), where we study the ecology and evolution of ancient microbial life. Message me if you’re interested in applying! 🌌🦠 www.simonsfoundation.org/grant/simons...

🚀 At #BreakthroughDiscuss2025 in Oxford, we explored "Life As We Don't Yet Know It". Watch Betul's lecture on how rebuilding ancient biosignatures and biological history can guide the search for extraterrestrial life. 🌌🔬 www.youtube.com/watch?v=JHVV...

New preprint: eukaryotic origins! 🥁 We propose that iron -not oxygen- may have delayed the rise of complex life. Our model reframes the “oxygen delay” puzzle: the gap between atmospheric O2 and early eukaryotic fossils may reflect iron-mediated stress, not for O2: www.biorxiv.org/content/10.1...

Excited to give a virtual seminar in the NASA LIFE RCN series next Tuesday June 10th, at 8am PST/11am EST. I'll be talking about the Chitin Raft Hypothesis and the rise of planktonic marine cyanobacteria. 🧪🦠⚒️🌐 #Paleobio #MEvoSky #MicroSky www.lifercn.org/events/2025-...

Science!

Wonderful to have former PhD student Katie McGrath visit us in Madison today! Katie is now a scientist at Roche. ✨ It's always a joy to see you Katie! We miss you and are so proud of all you're doing. Thanks for visiting us! 👩‍🔬✨ #AlumniVisit #WomenInSTEM

Such an inspiring story on following your passion, persistence and becoming a woman that leads the way in Science…

🚨 Know someone ready to dive into ancient microbial mysteries? 🧬 One of the most brilliant and supportive scientists we know, Morgan, is hiring a postdoc for Fall 2025! If you have skills in microbial ‘omics, phylogenetics, or genomics, this is your moment. 🌍🦠 👇 Learn more & share widely!

“You always have that thing in the back of your head: what would you rather be doing? And I was like, I wish I had thought of this experiment.” #HFScout @harmitmalik.bsky.social on @betulland.bsky.social’s work to resurrect Earth's oldest lifeforms. From HF + @scifri.bsky.social: bit.ly/4dXaqv7.

Want a listen that will, as @kacarlab.bsky.social puts it, 'wire you up?' "I will never forget that: I can hold a pen. And I can write. So, now, what do you do with it? What is the biggest question you can ask? What is the most important thing you can do with you life?"

The lab resurrecting ancient proteins to unlock life’s secrets: “I want to change the way we think about the past altogether,” says Dr. Betül Kaçar, an astrobiologist who studies the origin of life. bigthink.com/life/the-lab... Big Think

Forget Jurassic Park 🦖-- Hypothesis Fund Awardee @betulland.bsky.social is resurrecting lifeforms that are way, way older 🦠. Listen now on The Leap! ⬇️

Great piece

🚨 I’m hiring a postdoc for Fall 2025 with experience in microbial ‘omics data analysis and phylogenetics/genomics. Projects will be centered around ancient microbial ecology & evolution. Click here for more information: bpb-us-e1.wpmucdn.com/wp.txstate.e... Please share, thank you 🙏🏻

Take a break from the ugly of life and immerse yourself in the fascinating and uplifting.

At a time when many of us in science are reflecting on our place or path, the story of resilience shared by @kacarlab.bsky.social feels especially meaningful and deeply resonant.

Excited to share what I’ve been working on for the first part of my PhD!

Great interview with Betül @kacarlab.bsky.social on the importance of persistence in scientific exploration!

🧪🪐 Big week for ancient nitrogen! Checkout these three papers from our lab: 1️⃣ Rucker et al.: Engineered ancient nitrogenases to trace 2 billion years of biosignature reliability ➡️ www.biorxiv.org/content/10.1...
