Join us tomorrow, May 13th, at 11 AM ET/3 PM UTC for our next seminar (a DOUBLE header!) featuring Dr. Jennifer Macalady (@jmacalad) from @GeoscPSU and Dr. Alta Howells from @CUBoulder #astrobiology

SOUND ON. You’re hearing the first howl of a dire wolf in over 10,000 years. Meet Romulus and Remus—the world’s first de-extinct animals, born on October 1, 2024. The dire wolf has been extinct for over 10,000 years. These two wolves were brought back from extinction using genetic edits derived from a complete dire wolf genome, meticulously reconstructed by Colossal from ancient DNA found in fossils dating back 11,500 and 72,000 years. This moment marks not only a milestone for us as a company but also a leap forward for science, conservation, and humanity. From the beginning, our goal has been clear: “To revolutionize history and be the first company to use CRISPR technology successfully in the de-extinction of previously lost species.” By achieving this, we continue to push forward our broader mission on—accepting humanity’s duty to restore Earth to a healthier state. But this isn’t just our moment—it’s one for science, our planet, and humankind. All of which we love and are passionate about. Now, close your eyes and listen to that howl once more. Think about what this means for all of us.

Check out this exciting new paper from Jiang et al.! Mimicking lightning-induced electrochemistry on the early Earth | PNAS pnas.org/doi/abs/10.107…

New preprint: ATP is the energy currency of life as we know it. We show that the use of ATP goes way back in time by the life-essential enzyme nitrogenase and it was a biophysical necessity. In collaboration with the Seefeldt lab, congrats Derek & Holly! biorxiv.org/content/10.110…

We are excited for the inaugural seminar of the LIFE RCN Seminar Series tomorrow! It will be given by Dr. Tori Hoehler from @NASAAmes. The title of his talk is “The Metabolic Rate of the Biosphere and its Components” The seminar will be held at 1PM ET/5PM UTC. #astrobiology

@CharlesCockell Great idea! 🙂

Just out in Nature Communications: cytosine and thymine now added to the list of nucleobases found in meteorites! nature.com/articles/s4146… Also for a commentary of the findings: nasa.gov/feature/goddar…

Don't regret anything in life. If it's good, it's wonderful. If it's bad, it's experience! When you win, you win. When you lose, you learn.
