- Reposted by Noelle HeldThe COBS working group is offering an experimental design workshop before Ocean Sciences in Glasgow in Feb 2026! 🌊 Join us for a day of learning about designing and analysing multiple stressor experiments without getting multiply stressed out. forms.office.com/Pages/Respon...
- Reposted by Noelle Held🌊Curious how multi-nutrient scarcity impacts marine microbes🦠? Excited to announce our #OSM26 session, Glasgow Feb 22-27! Join us in bridging cell biology, modelling & oceanography! tinyurl.com/zzt5s9su @exetermarine.bsky.social @thembauk.bsky.social @proteocean.bsky.social @cmarkmoore.bsky.social
- 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. usc.wd5.myworkdayjobs.com/en-US/Extern...
- Super glad to share two new papers about how nutrient gradients impact alkaline phosphatase in the ocean. This was "that project" which followed from PhD to Postdoc to Assist. Prof, motivated by awesome collaborators! egusphere.copernicus.org/preprints/20... egusphere.copernicus.org/preprints/20...
- 🔥Thanks, Don Beyer and staff!
- The Trump Administration's list of censored scientific terms that get NSF grant proposals flagged contains "women” and “female”, but no mention of “men” or “male.” There is “black” and “indigenous” on this list, but no “white.” The only identity not censored is mine. youtu.be/dHXbpj1Z3UU
- Reposted by Noelle Held🚨 The Trump administration is attempting to seize power beyond what the Constitution allows—giving Elon Musk, an unelected billionaire, unchecked influence. As a federal scientist, expert, or civil servant, you have rights. Don’t let them bully you. These resources can help: act.ucsusa.org/4hqSJoz
- We’ve been sampling the Santa Monica bay since Jan for changes in the marine microbiome due to runoff of debris from the fires. Today I brought a sampling buddy along. We should teach him to pull the cart.
- Reposted by Noelle HeldReiterating my call to fellow federally-funded scientists: Call your reps, tell them how this hurts science and everything good that comes from science (Also non-scientists, and scientists without federal funding! But the more of us who can directly speak to the impacts of these freezes the better)
- The National Science Foundation cancelled over 60 grant review panels today, effectively grinding funding of new projects to a halt. The so-far indefinite pause comes as NSF grapples with the impact Trump's executive orders will have on their grantmaking process. www.npr.org/sections/sho...

- I really wanted a long distance penpal as a kid - so a fun upside of the transientness of early career academia is that I am now sending new years cards to friends all over the world - just posted to Germany, Australia, Switzerland, the UK, Italy, Russia, France, Canada, and Chile!
- Reposted by Noelle HeldWe showed that #metaproteomics based "Stable isotope fingerprinting can directly link intestinal microorganisms with their carbon source and captures diet-induced substrate switching in vivo" www.biorxiv.org/content/10.1... Great work by Angie Mordant and Alfredo Blakeley-Ruiz @alfredob.bsky.social
- More good news to round out the year, Proteocean Lab PhD student Mia Franks is a Wrigley Institute Graduate Fellow! She joins a very cool, very diverse group of student researchers and will quantify nutrient colimitation in the San Pedro Channel. Yay Mia! dornsife.usc.edu/wrigley/2024...
- 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 @michaelmanhart.bsky.social. Let us know what you think! www.pnas.org/doi/10.1073/pnas.2400304121
- This work is transforming my own approach to nutrient incubations and omics data - how can we design these to be more quantitative?
- 5 years ago toda I defended my thesis (thanks for the reminder @maksaito.bsky.social!) 1 year ago today was my first day in LA. Time flies! The dog is not impressed.
- Reposted by Noelle HeldWe're still looking for a postdoc in metabolic modeling and culture-based validation. If it sounds like you, reach out to discuss! www.isme-microbes.org/jobs/postdoc...
- And it takes me two weeks to install a python library.
- Just incredible news on reviving Voyager I. Think of it: a computer chip 15 billion(!) miles away is broken. The solution is to repackage & move key software, w/ code sent via radio signal that takes 22+ hrs to reach that little 46yr old machine. AND IT IS WORKING. blogs.nasa.gov/voyager/2024...
- Starting my rejections garden. Adding a plant for every no. Going strong at 4 months in - I’ll have an epic office garden in no time. Anyway, even though it feels crummy, there can be growth. 🌿
- Has anyone had experience with a preprint being published, along with a bunch of AI text and a fake image, on one of those NFT sites? It grosses me out, not sure of legality??
- Reposted by Noelle HeldMicrobes need many different resources, but do some of these resources simultaneously COLIMIT growth? @proteocean.bsky.social and I provide a new review of this concept, a summary of evidence that colimitation occurs in natural environments, and its causes/consequences. doi.org/10.32942/X2S... 1/6
- Time for another new lab poll - What ultra pure water system does your lab have and do you like it?
- Second growth on HEPES and basically all buffers.
- Cool opportunity if you’d like to postdoc at USC and work across departments in sustainability! Awesomely, the fellowship includes targeted career development! We’re ramping up relevant themes in the proteocean lab, contact me! www.ssf.usc.edu
- In times like these the Oceanography training really pays off - I basically got a PhD in shipping weird stuff halfway across the world.
- First instance of helpless panic waiting for a grant to route through approvals, minutes before agency deadline: ✅ Also, first instance of grant manager angel saving the day: ✅ What right of passage is next?
- Reposted by Noelle HeldOur lab is recruiting a Ph.D. student for fall 2024! If you are interested in the ecology, evolution, and systems biology of microbial communities (especially using theory and modeling), please apply by November 1 according to the attached ad and link qevomicrolab.org/wp-content/u...
- Let’s talk about nutrient (co)limitation as a quantitative property of microbial populations and communities! Plus, we show that colimitation for two essential nutrients is accessible in laboratory conditions. Preprint here: www.biorxiv.org/content/10.1...
- Reposted by Noelle HeldI’m working to find examples on my end, but if anyone would be willing to share a successful NIH K99 related to microbial ecology and/or evolution it would be much appreciated.
