Beyond thrilled to share that our study has been published!
This project encompasses years of work, including my thesis research on Asgard archaea in the @archaeal.bsky.social lab at @utmsi.bsky.social and
@texasscience.bsky.social!!!

Congrats Katy and all others involved. Phenomenal work!!

OPINIE - De nieuwe strategie van RU is een gedurfde visie die de bescheidenheid van zich afschudt, schrijft Mike Jetten : 'we kunnen het ons niet veroorloven een generatie briljante talenten te verliezen omdat ze te uitgeput zijn door bureaucratie & gebrek aan budgetten www.voxweb.nl/opinie/meer-...

Our latest preprint: Together with the team of Jan Löwe, @danieltamarit.bsky.social and many others we discovered and characterized several Asgard tubulin genes and propose that microtubule architecture and dynamics evolved in Asgard archaea prior to eukaryogenesis

Great paper, thanks for sharing!

A Cell So Minimal That It Challenges Definitions of Life | Quanta Magazine The newly described microbe represents a world of parasitic, intercellular biodiversity only beginning to be revealed by genome sequencing.

A newly discovered archaeal cell has a tiny genome and can’t metabolize biomolecules. It’s upending biologists’ definition of a living thing. “These types of organisms have been found before, but not as extreme as this,” said microbiologist Thijs Ettema.

New preprint out: Although sulfate reduction at pH < 3 is reported in acid mine/rock drainage environments, isolated aSRB have never matched this limit. Using axenic planktonic chemostats plus DNA/RNA and lipid analyses, we demonstrate aSRB activity and underlying physiology at AMD-like pH.

Coincidental and exciting! Anaerobic methanotrophic archaea (ANME) do like carbon monoxide - two independent studies showcasing CO metabolism across freshwater and marine ANME (ANME-2d and -2b).

New insights into how microbes regulate methane balance | Radboud University Research by microbiologists Martijn Wissink and Cornelia Welte of Radboud University, among others, is helping us understand how microorganisms regulate the methane balance .

Microbiologists Martijn Wissink and @cuwelte.bsky.social, among others, are helping us understand how microorganisms regulate the methane balance. 🦠 🫧 The scientists have demonstrated how a methane-converting enzyme (MCR) works in detail.
