Proteocean Lab’s first big conference! We love the marine microbes GRC!

[Noelle A. Held @proteocean]

I am hiring a research/technical specialist/manager to help us make the most out of new LC-MS instrumentation at USC! Please share the word and write me for more details. https://t.co/7vS22pvmic...

These experiments are transforming how I think about field experiments and omics datasets - how can we make them more quantitative?

[Noelle A. Held @proteocean]

What does it really mean to be in nutrient colimitation? We demonstrate a distinct growth phenotype and that (co)limitation can (and should!) be quantified. The result of many late afternoon chats with @Michael_Manhart.

The inaugural Alma Dal Co School on Collective Behavior will be in Venice (Sep 29-Oct 4, 2025). This unique school honors Alma (1989-2022), whose brilliant work bridging physics and microbiology revealed how metabolic interactions structure microbial communities. @Alma_DalCo 1/12

The science supply chain is so ridiculous. You can do your best on sustainability in the lab and then VWR sends you stir bars each in a huge, double walled cardboard box. 🙃

I'm back with another non-academic Mom In Science update: she's with her poster at another conference, this time invited! She's thinking about writing it up as a manuscript; that would be so awesome.

[Noelle A. Held @proteocean]

I am so proud of my mom who has been an RN for 40 years, went back for a masters in her 50s, started doing research, and is presenting a poster at a conference for the first time today. I hope I also keep doing new things when I am 62!

[Kavli Institute for Theoretical Physics @KITP_UCSB]

New KITP Program! #MICROECO26
Coarse-graining Microbial Ecology: from Genes to Physiological Strategies to Communities across Environments

Dates: 5/18/26-6/18/26

Update: Mom's poster made the conference website and we're all really excited about it. I'll also point out that her poster is about reducing C-section infections by sending patients home with a cleanser that works but is nice enough that they enjoy using it as self-care. Go mom!

It’s not frivolous if you stick them on your field equipment.

[Noelle A. Held @proteocean]

Proteocean Lab is in the clean room today prepping for field incubations to minimize contamination by trace metals! It’s like entering a dance club - years can go by but I still got it 🍾

[Noelle A. Held @proteocean]

I highly recommend doing a postdoc in the MSE group!

@nonresidentdesi east coast of FL - baby loggerhead seaturtle tracks!

[Noelle A. Held @proteocean]

This is worth protecting.

[Noelle A. Held @proteocean]

I think that microbes experience nutrient limitation in a continuous way, but experiments aren't usually designed to capture that. Thoughts (and massive concept map) from @Michael_Manhart and I in the Microbial Systems and Synthetic Biology themed issue: https://t.co/Jt5hnnuiKV

[Noelle A. Held @proteocean]

It's been a month since ASMS - which talks have stuck with you/should I watch before the recordings disappear in September?

[Noelle A. Held @proteocean]

Pipettes Christmas!!!! #newlab

[Noelle A. Held @proteocean]

p.p.s. Just to show - totally different phenotypes with the normal gene (A&B) vs spontaneous mutation (E) and genetic knockout (G). It's wild!

[Noelle A. Held @proteocean]

What makes a sticky bacterium sticky? Turns out, it can just be one enzyme. The moral of this study was: sequence your freezer stocks!

p.s. the non clumping strain was an absolute nightmare for proteomics, which caused a quarter year stress cycle that ultimately ended up in the sequencing venture and me finally signing up for yoga teacher training. Hah!
