Excited to share our publication on microbes in and on deep sea methane seep carbonates!
Rock-hosted ANME-SRB can be reactivated. Some rocks have a black ANME biofilm! The surface harbors diverse divergent particulate methane monooxygenases. Read here:

I am really happy to have joined the
@kuesellab.bsky.social
in Jena Germany as a Senior Scientist! The people are great and I am looking forward to continuing methanotroph ecophysiology and genomics across ecosystems (aerobic and anaerobic).
Sea spiders (Sericosura) living on methane seep carbonates growing methanotrophs on exoskeleton - in pyramids! - and ingesting them. Many carrying eggs..
Really cool to see this come out, congrats @ Bianca and Shana! – honored to have been part of the collaboration 😊

Women were historically excluded from health studies on the grounds that hormone fluctuations introduced "noise" into the data, and this has left us with a lack of understanding about a range of conditions

If someone tells you "we all have the same number of hours in a week" - ignore them
I spend 3+ hours a week, since 2013, exclusively on ankle pt exercises so I can *walk* every day. (Removing the pt time immediately after surgery)
We all have unique things but it makes our weeks unequal.
Bisson et al. (2025) highlights a hidden GHG pathway: stream banks with active groundwater discharge emit more CO₂ & act as N₂O sources, while non-discharging banks can be N₂O sinks

DEI is under attack, but the stakes are higher than many realize. Universities *must stand firm* in defending it. I lay out why in my latest piece for Nature.
Silence is complicity. Without DEI, we fail our students, our research, and our future.

Geological society of America releases statement in support of science.
Good to see this from the Geological Society of America #StandUpForScience #ScienceForAll 🧪⚒️
Great. Trickle down works for racism, of course.

The @agu.org Biogeosciences newsletter is out w/ DEI committee statement! go.agu.org/index.php/em...
Cool, I am curious how long do you have to/can you keep them like this?
And I am an ally. If you are too, let the world know.
Finally read the below piece from Chanda Prescod-Weinstein, written in 2018 (not tagging intentionally, you can easily find her if you need ;). Exceedingly good and really makes me think about the way we've structured things at UC.
#netDE needs someone!
I’m too overwhelmed with eldercare details for the next month.
I spent some time cleaning up my repo demonstrating how to use the NCBI Datasets REST API to do automated and/or bulk retrieval of genomes, by accession or by taxonomy. It's not super well documented but it does all seem to work :). Enjoy!
Your lab scissors are actually a parafilmase - a highly specialized enzyme that catalyzes the precise cutting of parafilm through a metal-dependent mechanism
NGL, kinda glad to get emails from my big project's head PI that still has pronouns in it. No anticipatory compliance over here.
👍👍. Research without DEI does not seem like a great idea to me.
I thank everyone on ship, the orphanlab and coauthors for making this research possible 🙏, and the funding agencies for funding this research.
📝 Distinct Microbial Communities Within and On Seep Carbonates Support Long-term Anaerobic Oxidation of Methane and Novel pMMO Diversity

🔹 Dormant vs. active communities
🔹 Resilience: Anaerobic CH₄ oxidation reactivates after 300–700 days 🕰️
🔹 A new potential ANME partner
🔹 Unique surface biofilms, including a striking black ANME-SRB biofilm
🔹 Divergent pMMO in Methylophagaceae

At methane seeps, CH₄-derived carbonate rocks serve as CH₄ and C sinks.
• But how do their microbial communities respond to changing seep activity? 🌊💨
• & who lives on the surface vs interior?
