My lab is attempting ancestral reconstruction of some very large trees using ALEml (amalgamated likelihood). Does anyone know if a multithreaded implementation of ALE is available somewhere? Our HPC is unhappy with us running a single thread for >24h on the bigmem node...

Aggresomes protect mRNA under stress in Escherichia coli
www.nature.com/articles/s41... "prolonged stress leading to ATP depletion in Escherichia coli results in increased aggresome formation, compaction and selective mRNA enrichment within these aggresomes" 🦠 #microsky #rnasky
Aggresomes protect mRNA under stress in Escherichia coli - Nature Microbiology
Ribonucleoprotein aggresomes exclude ribonucleases and protect mRNA to promote rapid translation reactivation and cellular recovery after stress alleviation in Escherichia coli.

🎯How did life get multicellular?

Five simple organisms could have the answer

"Single-celled species that often stick together in colonies have researchers rethinking the origin of animals."

I gave a symposium talk at the European Society for Evolutionary Biology 2025 (#eseb2025) meeting last week and this was my title slide showcasing how I was speaking as an independent scientist because @dalhousieu.bsky.social @dalhousie.bsky.social has locked us out.

ACL Circuit: Gut Signal Switch! 🦠

ACL is a density-dependent signaling mechanism in Bacteroidota that regulates the production of diverse secreted molecules via a unique lysine-based biosynthetic pathway playing an active role in the host.

To me the increasing economical and political power of older people, who have no stake in the future, is a concern. Lack of economic growth also challenges our social fabric, leading to polarization, especially combined with high inequality... but both still easier than climate change...
