It was a great meeting where I was able to show new work on proteins built with extraterrestrial amino acids! Looking forward for next!

"The symposium brought together researchers focused on diverse and varied ecosystems but united by their goal to discover and characterize microbial dark matter."

Wolbachia uses ankyrin repeats to target specific fly proteins | mBio Molecular interactions drive co-evolutionary arms races between hosts and pathogens. These interactions shape the structure and function of both host and parasite proteins, enabling immunity or virule...

Extremely proud of my student Will Hamilton and the work we've done to characterize Wolbachia ankyrin repeat proteins. TLDR: they do interact with specific Drosophila proteins! journals.asm.org/eprint/KXVNI...

If anyone knows the best companies, services, or labs, please provide me with their names and price range 💸
And we're also open to send samples to any lab that has TEM and would offer a help to scan these two bacteriophages for potential collaboration, so please don't hesitate to contact me 🙏🏻
Thanks

The Ancient Weapons Active in Your Immune System Today | Quanta Magazine Dozens of new discoveries reveal that defenses evolved by bacteria and viruses billions of years ago still define our own innate immune system.

Scientists are learning more about the ancient cellular machinery that underlies our immune system. The findings could lead to new medical treatments and biotechnological tools.

New publication out @natcomms.nature.com! We identify novel viruses that actively infect highly productive chemoautotrophs, and reveal key trophic interactions and virus-host dynamics that impact microbial carbon cycling in aphotic environments.

🚨New pub is live! It was really fun to write this with my friend @carolinamicro.bsky.social. If you're curious about how phylogenomics has shaped our understanding of early life and want guidance on how to do this kind of work yourself, then this review is for you. Enjoy! 🚀

GBE | Cosmopolitan Gene Families With Known Functions Are Hotspots for the Evolution of Novel Genes in Stony Corals Photos: Erin Chille / Debashish Bhattacharya

Stephens, Kulczyk & @bhattacharyalab.bsky.social suggest that dark genes (those with no ascribable biological function) in stony corals originated via bursts of lineage-specific duplication, often from genes with known functions.

Our work on chromatin evolution in brown algae is now published in @natecoevo.nature.com! We show that developmentally complex brown algae evolved without epigenetic silencing pathways long thought universal, underscoring why non-model lineages are important to study. www.nature.com/articles/s41...

Honeybee swarms do not come together and fall apart in the same way 🐝

Hi! You could contact Jasmina Wiemann (@jwiemann.bsky.social) I think she would be great! I would be also interested since I work with the interactions between elements and life constrains in evolution with interests in philo of science!

Despite 150 years of evolution, grasses and Crassulacean succulents use the SAME gene to make subsidiary cells! 🤯

Excited to share our lab's new paper in Current Biology featuring MS student Sydney Schultz's work. We show that a polar alga carries large amount of giant viral DNA in its genome, and many of the viral genes respond to stress - with implications for host adaptation.

An overview of bacterial multicellular formations: biofilms, filaments, free-floating aggregates, motile collectives and fruiting bodies. For each form, we mention an analogous eukaryotic multicellular form (respectively animal epitelia, filaments in fungi, Volvox, Dictyostelium/social animals, Dictyostelium and other slime moulds)

How common is multicellularity in bacteria? And archaea?
And how does it evolve?

We wrote a short review "On the architecture and evolution of prokaryotic multicellularity".

Horizontal gene transfer is often depicted as a process distributing pre-existing functions to novel genetic backgrounds. Yet HGT can also increase the rate of functional innovation after transfer. Here's a brief review on the topic: ecoevorxiv.org/repository/v... #evosky #microsky
