The #UConn Microbial Ecophysiology Lab studies the biology of methane-producing microbes (methanogens or methanogenic archaea) and their role in ecosystems & host-associated microbiomes.

We are people who do science, but we also actively work to include diverse perspectives in higher education.

Out in Science Advances: Our #cryoEM structure of HFTV1, a virus infecting the halophile #archaea. *First full atomic structure (containing all structural proteins) of any tailed virus!* Congrats and thanks to all co-authors and our fantastic collaborators! www.science.org/doi/10.1126/...
Cryo-EM resolves the structure of the archaeal dsDNA virus HFTV1 from head to tail
This structure of an archaeal tailed virus (arTV) provides detailed insights into arTV assembly and infection mechanisms.

Secretion Days was a great meeting! Congratulations to the organisers and speakers, you were fantastic!!! Special kudos for the outstanding keynote speaker @archaellum.bsky.social I fell in love with archaea ❤️ and I am super excited to realise there is still so much to be discovered and be learnt

Our October issue is out now!

The images are negatively stained electron micrographs taken from archaella bundles isolated from the archaeon Sulfolobus acidocaldarius.

The fiscal year is over.

So how was the NIH appropriation committed?

A long thread with institute by institute results about where the money went.

Getting ready for a presentation about Skype a Scientist, so I was crunching the numbers on what we've done this year & no wonder I'm tired.

Philly event attendees: 433
Zines distributed: 5,900
Seed packets distributed: 10,000
Online event attendees: 1,355
Classrooms matched w/scientists: 3,488
A ppt slide that says "weaving science into everyday" with 6 examples, including "getting coffee, at a street festival, trick or treating, on the road, at a community meeting, at the corner bar" and each of those has a picture associated like a squid zine at coffee, a table of squid stuff with a man dressed as a squid for street festival, squid postcards and candy for trick or treating, the squidmobile for road, me taking in front of people for community meeting, and bar coasters for corner bar

We kicked off the new school year with the launch of the BioFoundry for Extreme and Exceptional Fungi, Archaea and Bacteria (ExFAB). The new facility will allow researchers to make novel discoveries using previously unstudied microbes that could generate advances in biotechnology & biomanufacturing.

New in JB: In this minireview, Rotaru, Kotoky et al. explore the Kotoky review the surface biology of Methanosarcina, an archaeon, with respect to their EET strategies, and biogeochemical and industrial roles. Some cool biology!

I had a great time participating in the @vaam-microbes.bsky.social Archaea Meeting at the @synmikro.bsky.social of @unimarburg.bsky.social this week. The wonderful talks once again demonstrated how important the research of the third domain of life is 🤓 🔬 🧫 .

Stability vs flexibility: reshaping archaeal membranes in silico

This ‘fundamental’ study characterises the mechanics and stability of bolalipids from archaeal membranes using a minimalist, physics-based computational model.

Isolation of Marsarchaeota, now named Tardisphaerales. Added to my pile of shame (to be read papers).
