Thank you Dr. E!!! Excited to get those electrons flowin’ ⚡️

Thank you!!

Delighted to share that I will be joining the faculty in Earth, Marine, and Environmental Science at UNC Chapel Hill! The Baker Lab will be opening later this summer. Stay tuned 🦠🧫🔬

Chesapeake Community Research Symposium 2026 Home The Chesapeake Community Modeling Program will convene the 2026 edition of our biennial symposium June 1-3, 2026, in Annapolis, Maryland.

Come to the Chesapeake Community Research Symposium and consider submitting an abstract to our session, “Molecular Approaches for Chesapeake Bay Ecology and Biogeochemical Functions: from Genes to Insights”! ccmp2026.chesapeake.org#abstractsubm...

DOE Establishes the Office of Science Advisory Committee The Department of Energy (DOE) today announced the establishment of the Office of Science Advisory Committee (SCAC).

Lost in the many news of last week was this press release about the dissolution of the DOE Office of Science advisory committees and replacement with a new, integrated, single Office of Science Advisory Committee (SCAC): www.energy.gov/science/arti...

Microbial exoenzymes catalyzed the transition to an oxygenated Earth Microbial exoenzymes, extracellular enzymes secreted to degrade complex organic polymers, are essential for recycling carbon and nutrients, thus sustaining primary productivity in todays oceans. Yet, ...

🚨New preprint from our lab!🚨

We trace the evolution of microbial exoenzymes and uncover their role in Earth’s oxygenation. By recycling nutrients, exoenzymes helped fuel cyanobacteria and set off feedbacks that sustained the long-term rise of O₂.

We interrupt your regularly scheduled doom-scrolling with some science pics from our fieldwork on the Chesapeake Bay!

Exclusive: NSF stops awarding new grants and funding existing ones US science funder also plans to screen grant applications for compliance with ‘agency priorities’.

I talked to Nature about the latest development at NSF, which is a five-alarm fire for American science. The scale of immediate impact is massive. We narrowly escaped this affecting @viralemergence.org for now, but will have to shut down in a few months if this stays.

⚒️🧪 Even more sobering to me is that by removing the nodules, which take millions of years to form, the very slow ecosystem recovery will be to a very different state than what was there before.

A signal of our thoughtlessness that could last until the ocean floor itself is subducted.

Eukaryotes’ closest relatives are internally simple syntrophic archaea Eukaryotes are theorized to have originated from an archaeal phylum Promethearchaeota (formerly ‘Asgard’ archaea)[1][1],[2][2]. The first cultured representatives revealed valuable insight[3][3],[4][4...

I absolutely love this work❗️

Isolation of two strains belonging to the order proposed as FECA’s closest relative, ‘Hodarchaeales’, as members of a pure co- and tri-culture with methanogenic partners.

Today, we stand up for science.

What 2 days of sampling looks like 😅

Legitmately thrilled to share our latest work, in which @fernpizza.bsky.social solved an experimental challenge in plasmid biology as old as the field: measuring how plasmids compete and evolve within individual cells!

Firings happening right now at the NSF.

Studies only making reads available may satisfy journal requirements but do not serve the larger community.

If you work with any form of metagenomics/genomics data, and are for open access and FAIR data policies...Please consider making ALL your data public (genomes, proteins, reads, metadata).

Please share! This is a great opportunity for early career geobiologists, geochemists, sedimentologists, microbiologists, and evolutionary biologists

Ridgeline chart showing the distribution of global daily air temperature differences from the pre-industrial reference period (1850-1900), for every year between 1940 and 2024. Each individual year resembles a hill, shaded in a darker shade of red and further to the right for warmer years. The trend is clearly towards warmer years, with 2024 standing out as first year above 1.5C.

NEW: 2024 has just been confirmed as the warmest year on record, and the first to breach the 1.5C threshold.

We used a ridgeline (Joy Division inspired) chart to visualise daily temperature anomalies since 1940.

2024 clearly stands out with 100% of its days above 1.3C and 75% above 1.5C.

Merry Christmas to all those that celebrate, and to my fellow MOT, have a bright first night of Chanukah!

Reposting this again - We are looking for a postdoc to study the physiology, evolution, and cell biology of anaerobic ciliate-methanogen symbioses using 'omics, experiments, and/or microscopy. Still accepting inquiries, and I would love to hear from interested candidates.

Ha no way! I loved geeking out about iron with you!
