Honored to present our research on archaeal toxin-antitoxin systems at the International Thermophiles Congress 2025—great discussions and inspiring science all around! #Thermophiles2025 #Microbiology @IndiaDST @ANRFIndia @bose_institute

Thermophiles 2025 kicked off on a high note at the University of Münster’s Schloss. Prof. Jenny Littlechild opened the congress, with excellent keynotes by Prof. Sonja-Verena Albers and Prof. William Martin. Great to reconnect with colleagues! #Thermophiles2025

An Asgard archaeon from a modern analog of ancient microbial mats It has been proposed that eukaryotic cells evolved via symbiosis between sulfate-reducing bacteria and hydrogen-producing archaea. Here we describe a highly enriched culture of a novel Asgard archaeon...

📣 New paper alert!
One of the most exciting projects we've done in recent years is now out on BioRxiv: "An Asgard archaeon from a modern analog of ancient microbial mats".

Glimpse into early complex life! ❄️🦠 🔬🧬

Unravelling the role of the A domain and N-terminal alpha-helices of FtsY in archaeal signal recognition particle Signal recognition particle (SRP) system is critical for protein translocation across membranes in all domains of life. In archaea, this pathway relie…

New results from the lab!!!
Our recent study analyzes the archaeal SRP system, focusing on the FtsY protein's N-terminal domain. This work highlights the key role of the A domain and N-terminal alpha helices in generating the functional TC in archaea.

Join us in beautiful York, UK!

Great opportunity for all archaea lovers out there!

Interested in the complexity of gene expression in Archaea? We have three open postdoc positions focussing on the coupling of transcription and translation using functional genomics, structural biology and molecular biology in Finn Werner's lab at UCL. Links below!

Great to see that Department of Science and Technology, Government of India showcased our work on VapBC4 toxin-antitoxin system of Sulfolobus.

The archaeon Sulfolobus acidocaldarius has four different surface filaments. Each of them plays its special role in motility, adhesion, biofilm formation and mating. Our latest cryoEM foray into three of these unique structures is now published: www.nature.com/articles/s41...

What is the role of MinD proteins in Archaea? They are not involved in positioning of the cell division proteins, but might rather position the archaellum machinery at the poles and interact with cytosceletal proteins. New paper alert coming!

Understanding the tolerance of halophilic archaea to stress landscapes The tolerance responses of nine Haloarchaea species were analysed under 70 different conditions, including various salinities, temperatures, oxidative stress and the presence of metals. In general, a...

have you ever heard about sheaths? New paper out on these fascinating envelope structures in #archaea!! See the thread of @sonaida.bsky.social👇

Last day at the @aglab-2024.bsky.social , Bose Institute, and its an emotional one- feeling sad to leave as well as excited for what lies ahead. Grateful for all the memories here and looking forward to joining the Mullins Lab at UCSF to do wonderful science with his team..

Not sure who out there is interested… but …. Let me know if you are interested in joining.

Where are my bacterial (and archaea!) #RNAsky peeps? Mark your calendars for Sept 1-4 next year for the Microbial RNA meeting in Strasbourg. It’s my absolute favorite conference, so an ideal place to be an invited speaker for the first time :) Hope to see lots of folks there! microbialrnameeting.com

Role of VapBC4 toxin-antitoxin system of Sulfolobus acidocaldarius in heat stress adaptation | mBio This research enhances our knowledge of toxin-antitoxin (TA) systems in archaea, specifically in the thermoacidophilic archaeon Sulfolobus acidocaldarius. TA systems are widespread in both bacterial and archaeal genomes, indicating their evolutionary ...

The story is finally out!!! Here, we showed multiple functions of the VapBC4 toxin-antitoxin of Sulfolobus acidocaldarius under stress. Thanks to @archaellum.bsky.social for an excellent collaboration.
