Starting this week, I set aside one hour each week to meet ECRs outside my group who want to discuss career development, mentorship, or any non-technical professional questions. Here is a blog that explains my motivation for this and how to schedule a meeting: merenlab.org/2025/11/16/E...

Some really fantastic discussion in this live stream.

It’s Friday: a new episode of #MattersMicrobial! This week, Dr. Julie Maresca joins the #QualityQuorum to discuss microbes and concrete and road salt! Please spread the #GoodMicrobialWord? @ASMicrobiology @univpugetsound @microbe.tv youtu.be/3JpbySeOO20?...

Starting at 7pm Central I will be streaming from the bottom of the ocean off the coast of Uruguay! Feel free to join and ask questions. www.youtube.com/@SchmidtOcean

📣New preprint alert! Check out this new preprint by Zhu et al. that quantifies and compares labile exometabolites from six axenic strains of marine phytoplankton 🌊 to identify key chemical currencies within the marine chemical-microbial network! 🧪🦠

Does anyone by any chance have a Ni-CODH database they could share it with me? Thanks!

I'm tasked with creating a career roadmap for our major (Biology), from enrollment to hire post grad. Does anyone have examples of ones they've done or find useful?

So, so cool to see all these microbial culture focused people all in the same room (in-person or virtual) at the @jgi.doe.gov Cultivation Jamboree!

Have any of my followers implemented a "flipped classroom" for an upper division Environmental Micro (or related) course? I am planning a re-work for my current class for next fall and considering a flipped modality.

Good opportunity to be on Mark's podcast. Highly recommend! #microsky

We've had a bad month for equipment failure this month. Three expensive incubators are down and one of our flow cytometers. How do y'all deal with this financially once startup is gone? Do you budget in proposals for it? Do your departments help? College funds?

ICYMI: Our latest shows what happens to transcriptional and metabolic profiles in a desiccated soil bacterium. To simplify things, I've attached a visual abstract. Comments on the preprint are welcome! #microsky #microbesky www.biorxiv.org/content/10.1...

Please repost: What are the current costs of kit-based RNA extractions per sample? Qiagen quoted my grad student a "discount" that came to $10/sample. That seemed /way/ too high

📣Postdoc opportunity @nordcee.bsky.social , University of Southern Denmark! 📣 Join us and work with Bo Thamdrup and me on microbial dark oxygen production in marine oxygen minimum zones! Please share widely! Deadline: 17 November More information can be found here: tinyurl.com/2vuur3wh

Please share this with anyone who may be interested in a post-doc in Germany: jobs.awi.de/Vacancies/20... This is quite an exciting opportunity to push the boundaries of what is known regarding the molecular basis of the formation and demise of photosymbiotic relationships in marine habitats.

Come be my chair at The University of Arizona! We have great bike riding, hiking, and of course, science! arizona.csod.com/ux/ats/caree...

For y'all y'all from the mid-atlantic-ish area of the US. www.youtube.com/watch?v=UL34... @jenbiddle.bsky.social @surtlab.bsky.social

University of Arizona (kind of) rejects the Trump compact I’m not super happy but I’m not super disappointed…we kinda half assed the reaction here

I'm delighted our paper is out: doi.org/10.1093/isme... With new SAR11 isolate genomes and time-series metagenomes, we reveal coastal and offshore SAR11 ecotypes, identify associated metabolic traits, and pinpoint selective gene sweeps as a likely evolutionary driver to niche partitioning. 🌊🦠

📣#MTTM Annika Gomez is a @simonsfoundation.org Postdoc Fellow in Marine Microbial Ecology in the Dyhrman Group @columbiauniversity.bsky.social. She studies marine viruses that exert a major influence on the fate of organic carbon in phytoplankton 🌊using ‘omics and culturing methods.

What type of #microscopy would allow for watching real time cell division of an anaerobic bacterium (~1 x 0.5 um rod) at resolution high enough to view internal structure? Doubling time of ~2 days. #MicroSky

I finally bit the bullet and got an Athletic Brewing membership (the NA beer company) and it's so worth it. I get the same crisp AHHHHH feeling when I get home and put my legs up while cutting back on alcohol that frankly doesn't make me feel good. And I get to enjoy them on the go.

New paper: Dried soil bacteria enter dormancy with "frozen" RNA & metabolite profiles—but water vapor alone can wake them up! #Microbiology #SoilScience #Dormancy #ClimateChange #MicroSky

Last day to apply to come work with me on developing AI approaches to understanding pangenome evolution www.jobs.ac.uk/job/DOU184/p...

Tucson wildlife operates on a simple principle: if it can't maim you, it'll destroy your property instead. Today's culprit? Packrats in my engine bay. Chewed straight through the wiring harness to my transmission. Had *just enough* wire left to butt-connect everything back together and limp away.

This was a great read. I feel similarly.

We're looking for two new U of Arizona undergraduate researchers to join our group. More details below. uncultured.carinilab.com/p/were-hirin...

Good opportunity!

👀

We're hiring for several positions (a post-bac researcher in #transcriptomics, a #phage #postdoc, a senior researcher (broad topics) and a graduate student to work on #ciliates) - find info here: www.marine.usf.edu/genomics/app...

UMass Amherst Microbiology is hiring a tenure-track virologist. Come work with me! 🦠🧪 careers.umass.edu/amherst/en-u...

The job is still open. Get your application in ASAP. Or just pass it on to somebody that might be interested.

One more day to apply to our lab's Ph.D. position for fall 2026 bsky.app/profile/mich...

Neat paper! Way back when, we speculated SAR11 could assimilate glycolate by oxidizing to glyoxylate and slapping an ammonia on it to produce glycine. Perhaps other taxa assimilate it similarly. www.nature.com/articles/ism...

One of the biggest things I truly love about Arizona is that we do not partake in the clock tomfoolery twice a year.

SO CLOSE to submitting our last paper that was started pre-pandemic!

What are folks using for calling genes these days in isolate genomes: PGAP, Bakta, or Prokka? This is for a 70% GC genome of a very novel lineage.

New post up about Generative AI in academic research settings. tl;dr : I'm mostly in favor of it, but with increased transparency. open.substack.com/pub/carinila...

We have some full length 16S data from isolates that we'd like to match to ASV-level V4-V5 microbiomes from the same samples. It's pretty messy, especially for strains with multiple copies of 16S rRNA genes. Has anyone encountered this in their work, or in the lit? Any ideas how to approach this?

🚨New preprint from our lab!🚨 We trace the evolution of microbial exoenzymes and uncover their role in Earth’s oxygenation. By recycling nutrients, exoenzymes helped fuel cyanobacteria and set off feedbacks that sustained the long-term rise of O₂. #MicroSky 🧪 🦠 🌎 www.biorxiv.org/content/10.1...

Where are prople depositing metabolomics data these days? Both targeted and untargeted data. TYIA!

I know I'm touching the 3rd rail here, but what is your cost ceiling for open-access APCs, presuming you've already deposited a preprint? In today's funding environment this calculus changes

I am recruiting a Ph.D. student in microbial ecology, evolution, and systems biology for fall 2026. Please share! Details: qevomicrolab.org/Documents/Gr... Apply by October 1 here: forms.gle/38pPS1Ky84HB...

📢 New paper in @nature.com Microbes rock 🎸🤘 with sulfide and iron minerals I am very excited to share our recent study, which describes a previously unknown microbial energy metabolism ⚡⚡⚡🦠🧫⚡⚡⚡ 🆕 Microbial iron oxide respiration coupled to sulfide oxidation - MISO www.nature.com/articles/s41...

Asking for myself: does anyone know an Indigenous women in science at an Ivy League? I am looking for mentoring around navigating the specific elements of Ivy institutions as an early career rooted in community work… and I don’t seem to have any one to ask for advice. It’s lonely out here 🥺

The Weisberg Lab at Oregon State University is recruiting a postdoctoral scholar in molecular microbiology to study mobile genetic element host range and transmission in microbial communities. Please see the full job description here: files-dev.cqls.oregonstate.edu/Weisberg_Lab...
