Introducing ** Incendiamoeba **, a eukaryote that can live at temperatures well beyond what we thought possible. 63C!!

Read @hbrappap.bsky.social thread to see what we’ve already started to learn from this amazing organism!

So happy to announce our new preprint, “A geothermal amoeba sets a new upper temperature limit for eukaryotes.” We cultured a novel amoeba from Lassen Volcanic NP (CA, USA) that divides at 63°C (145°F) 🔥 - a new record for euk growth!

Time to start planning for ASM Microbe 2026! Among the amazing sessions announced (see link), Chris and I are thrilled to be convening “From the Rhizosphere to Pollinators: Studying Agricultural Microbiomes Across Biological Scales”. We can’t wait to see you all there! More details coming soon!
Some fantastic sessions being planned for ASM Microbe 2026, including "Long-term Dynamics of Environmental Microbiomes", and "Eco-evolutionary Dynamics of Phages and Their Roles in Horizontal Gene Transfer". Get your abstract(s) ready, and join us June 4–7, 2026 in D.C. ! asm.org/events/asm-m...

We have a new paper out, led by my PhD student Linda! Ni and Cu are common co-occurring contaminants. They are also synergistic in their toxicity. We examined the mechanisms of this synergism, finding that sulfur assimilation and Fe-S cluster biogenesis are targets.

14 years since we lost Lynn Margulis (November 22, 2011). Still can’t believe she’s gone.
A giant of biology, through her co-creation of the Gaia Hypothesis, & her endosymbiotic theory, she changed the way we see life, evolution, our planet, ourselves. I feel so privileged to have known her.

1/10 Genome maintenance by telomerase is a fundamental process in nearly all eukaryotes. But where does it come from?

Today, we report the discovery of telomerase homologs in a family of antiviral RTs, revealing an unexpected evolutionary origin in bacteria.
