📢 New paper in @nature.com

Microbes rock 🎸🤘 with sulfide and iron minerals

I am very excited to share our recent study, which describes a previously unknown microbial energy metabolism ⚡⚡⚡🦠🧫⚡⚡⚡

New paper alert! We suggest caution in the analyses of viral auxiliary metabolic genes and propose a new overarching term - 'auxiliary viral genes' (AVGs) to describe different types of such genes. @simrouxvirus.bsky.social #phagesky #Microsky www.nature.com/articles/s41...

I had such a great time doing this podcast! Thanks @markowenmartin.bsky.social for the chance to talk about snails and their microbial friends.
New week-new episode of the #MattersMicrobial podcast!! Dr. Roxanne Beinart of the University of Rhode Island joins the #QualityQuorum to chat about the work her group does on deep sea chemoautrophic communities & symbioses! Please spread the #GoodMicrobialWord?

Hydrology Paper of the Day @maggielangwig.bsky.social on how viruses evolved near deep-sea hydrothermal vents: a global perspective on genomes and taxonomy; how viruses are related; similarities along hydrothermal fields; host abundance and hydrothermal geology; and future research.
Very excited this part of my PhD is out 🎉 We describe vent viral and microbial traits that govern viral biogeography and contribute to mounting evidence that these communities are highly endemic, and thus likely vulnerable to disruptive activities like deep sea mining

The Tufts graduate student detained by federal authorities in Somerville has been sent to a Louisiana detention facility, despite a federal judge’s order telling US Immigration and Customs Enforcement not to remove her from Massachusetts without notice.

NEW: Sources tell my office that Treasury Secretary Bessent has granted DOGE *full* access to this system. Social Security and Medicare benefits, grants, payments to government contractors, including those that compete directly with Musk's own companies. All of it.

I made a 2024 resolution to watch 100 movies new to me. I ended up watching 101! And then because I am nerd I decided to turn my movies into figures and data!

I did all this in R, which allowed me to make new figures and challenge my skills! I used all the Wes Anderson color package.
