Just out: metagenomics with internal standards yields phylogenetically resolved genome ("~cell") counts of bacteria, archaea, and photosynthetic eukaryotes per L of seawater, over the AMT29 Atlantic transect, via "single copy" genes (recA, radA, psbO). Compares with microscopy and flow cytometry.

For a handy summary of what GRUMP is, feel free to view and share the following presentation from the CBIOMES 2025 annual meeting: slides.com/jcmcnch/cbio...

More than 100 scientists who work in Antarctica or care about having a strong U.S. research presence there have signed a letter calling for the U.S. to keep the Palmer in operation. (4/n)

Please Re-Post. Our global GRUMP microbial ocean database is out in Scientific Data! Unfractionated, single universal PCR, with Archaea, Bacteria, and Eukaryotes all on the same scale with the same denominator. Pole to pole, depths to 6000m. Lots of metadata. www.nature.com/articles/s41...

Out in Science! Zakem et al. mechanistically modeled global marine prokaryotic functional diversity, grounded with field data. Shifts in community composition drive respiration and thus biological C storage. This facilitates C cycle projections in a warming ocean www.science.org/doi/10.1126/...

ATTENTION: NSF GRANT RECIPIENTS We received a heads up from a trusted source that you should proactively download/print/screen shot any documentation on research.gov pertaining to your NSF awards, both those that are current and any that have closed in the last 5-6 years. 1/n

Just out - The first global ocean 3-Domain microbial survey where all organisms can be directly compared quantitatively. Unfractionated and amplified from just 2 primers (vetted with mock communities and metagenomics), so all with the same denominator. www.biorxiv.org/content/10.1...

🚨BREAKING. From a program officer at the National Science Foundation, a list of keywords that can cause a grant to be pulled. I will be sharing screenshots of these keywords along with a decision tree. Please share widely. This is a crisis for academic freedom & science.

Colleagues at federal science agencies are receiving these “deferred resignation” emails - essentially comply or resign choices 🧪 - www.opm.gov/fork

Registration and Abstract submission is open for Aquatic Virus Workshop 12 😍 - avw12.sciencesconf.org/resource/pag.... AVW is THE meeting for those exploring viruses infecting little things in water; it will fill up fast. So, register now and come to Banyuls-sur-Mer, a jewel on the Mediterranean.

🌍 Just published in 14+ journals! AMI & global leaders call for microbial solutions to tackle climate change. Let’s harness nature’s power to capture carbon & restore ecosystems—time to act! 🧬🌱 #ClimateAction #MicrobialSolutions #COP29Baku academic.oup.com/sumbio/artic...

Long-term ecological #research projects apart from being highly demanding, it deserves extra respect from the scientific community; funding agencies should consider the benefits of such projects #ecology #science #nature #evolution @ipbes.bsky.social @esci.bsky.social doi.org/10.1038/s415...
