My first first-author paper is posted! Glad to have this out! 🦠🚨🕺

We show that pGpp production depletes GTP, inhibits translation, and remodels the transcriptome faster than (p)ppGpp.

Conservation of sporulation genes and a transmembrane-containing Spo0B variant in Paenibacillus Sporulation is a strategy employed by many bacteria to survive harsh environmental conditions. The genus Paenibacillus includes spore-forming species notorious for spoiling pasteurized dairy products ...

Here we show that >90% of Paenibacillus encode a unique Spo0B with a transmembrane domain! TM domain helps it interact with its phosphorelay partners. Congrats to @isabellalin.bsky.social who left for grad school this week and her mentor @cassidyprints.bsky.social! www.biorxiv.org/content/10.1...

Microbial iron oxide respiration coupled to sulfide oxidation - Nature Genomic and biochemical analyses of prokaryotic sulfur metabolism identify diverse microorganisms with the capacity to oxidize sulfide using iron(iii).

The regime halted all federal grants then told UC administration if they pay $1 billion they could have them back.
It’s like ransomware.
UC is a public university system and we cannot do this.
So, no grants = no research and labs will shut down.
Are we great yet?

YebC2 resolves ribosome stalling and increases fitness of cells lacking EF-P and the ABCF ATPase YfmR Author summary Polyproline motifs are essential structural features of many proteins but are difficult for the ribosome to synthesize. EF-P reduces ribosome pausing at polyproline motifs. Here, we sho...

Latest work from the lab - we identify a translation factor, YebC2, that reduces ribosome stalling in B. subtilis!

Columbia Agrees to $200 Million Fine to Settle Fight With Trump

You can never bend the knee enough to appease an authoritarian bully.

This is a devastating blow to academic freedom & freedom of speech at Columbia.

Never in the history of this nation has there been an administration so intent on the utter destruction of higher education as we know it.

Today is a great day to be a Great Lakes aquatic microbial ecologist🤩 Just a few photos from our #LakeMichigan cruise 🌊 Microbial community sampling isn’t so bad especially when your office for the week looks like this🌅

We’re excited to share a new CRISPR-Cas12 genome editing system, highly efficient across multiple brown algae species!

Brown algae transformation has been challenging despite many thoughtful approaches over the years.

We hope this one is kelpful 🌿😅

Reminders to myself and others • Apply often, apply broadly, and diversify funding. • Fight misinformation about science and scientists (publicly and/or privately). • Use social media for advocacy, branding, and SciComm- expand your network. • Maximize your resources- learn how to do science on a budget. • Bring your whole self to science (when you can safely). • Celebrate All of your wins, big and small! • Always keep your options open and approach science and academia with flexibility.

“Approach difficult conversations with empathy.”

Wrapping up #ASMicrobe day 1 with the @bsingletons.bsky.social mixer. Great program to support and welcome first-timers to the conference. Huge shout out to #JoeJames for doing so much to support fellow microbiologists! @ASMICROBIOLOGY.BSKY.SOCIAL

To those who weren’t born yet or those like me who didn’t remember, this is why we have the EPA.

THANK U DREA!!!! Its been so awesome so far💖

Pet peeve: I hate how often ppl claim “all the researchers will just move to Europe/Canada!” You vastly under-estimate how little money there is there vs the USA- and unless that changes ASAP this loss is just going to decimate global science, full stop. 🧪🔭

#ASMMicrobe Day ✌️

Presented my poster and met so many incredible scientists! Please be welcome to come my rapid fire talk tomorrow in AES: Microbial Pioneers: Colonizing Earth’s Unique Habitats at 11:45AM😀

An empty booth at ASM that should have housed the NSF

Well this is f’in sad #ASMicrobe

Hey all - check this post if you’re at #ASMicrobe this weekend.

Let’s have a meet up tomorrow for a photo op of microbiologists on @bsky.app who are at #ASMicrobe!

Be there at 3 PM at the main entrance giant ASM sign!

In person meetups are super fun - please be there!

And plz repost!

I will be presenting my work: “Understanding the Ecological Effects of Floating Photovoltaics on Microbial Communities in Freshwater Ponds”
