Since I've new to 'blueocean', here's some background about me. I'm Clio the autonomous underwater vehicle (AUV) that, unusual for a AUV, operates only in vertical mode, collecting samples in profiles down to 6000m. I have 4 payload containing large volume filtration systems and incubators.🌊🔬

I know folks are using orbitraps to look at isotopes for geochemical applications with sulfur molecules. Also just had another geochemist colleague visiting to learn protein extraction to get at N isotopic signatures. I’ve always wanted to go next door and to use the AMS for C14 in peptides.

Excited to give a virtual seminar in the NASA LIFE RCN series next Tuesday June 10th, at 8am PST/11am EST.

I'll be talking about the Chitin Raft Hypothesis and the rise of planktonic marine cyanobacteria.

One visible impact of the illegal firing of NOAA Great Lakes Environmental Research Lab (GLERL) employees -

no 2025 data updates for water quality in W Lake Erie, meaning no public info on the harmful algal blooms.

We detected toxins in April, but we lost the folks who organize & report this data

Is the Zinc Hypothesis true? (Zn control of marine primary production). Apparently yes: by multiple independent lines of evidence, including zinc stress protein biomarkers, in the low pCO2 waters of a coastal Antarctica bloom. Thesis work by Riss Kell and many wonderful collabs. In Open review BG. 🌊

I talked to NIH officials, current and former, about what's been happening inside the agency since the Trump administration shut down their grantmaking pipeline in January. Their stories showed just how willing our new leaders are to break the law: www.theatlantic.com/health/archi...
Inside the Collapse at NIH
Administration officials pressured NIH to avoid clear advice from the agency’s own lawyers to restart grant funding now.

Excellent 🧵 on this evening's NIH announcement of a dramatic reduction in indirect rates for research institutions, which amounts to a generational restructuring of the US research and development ecosystem. These cuts are effective immediately, not just for new grants but for existing ones.
carlbergstrom.com
Carl T. Bergstrom @carlbergstrom.com · Feb 8
6. The policy does not just affect funding going forward. All existing NIH grants will have their indirect rates cut to 15% as of today, the date of issuance.

For a large university, this creates a sudden and catastrophic shortfall of hundreds of millions of dollars against already budgeted funds.

Well, hopefully not the about worst... We modeled how correlations work for environmental responsive transcripts and proteins because the starting inventory of both is small so the dynamic range is large, and why in log2 space many gene products don't correlate because of large protein inventories.

Hey Chris, generally speaking protein trends with biomass, which is highest in the upper ocean where the sunlight reaches. Even In the cold of Antarctica there are huge blooms due to nutrient rich upwelled waters. How climate change and warming will affect productivity is not well known.
