🌊🧪 New in Trends in Ecology & Evolution (OA): "Rare molecules as community architects." Robert Paine's sea star kept a whole tidal community standing. Can a rare molecule, at trace concentrations, do the same? 🔬 Two independent systems suggest maybe, and the piece asks how we'd actually test it.

Qualia goes where curiosity leads. This week, writer Philip Ball goes down a contentious rabbit hole to see if living organisms (including the rabbit) have agency, or do things for their own reasons. Read the latest column: www.quantamagazine.org/is-life-just...

Is Life Just Different? | Quanta Magazine
The idea of ‘biological agency’ — that life devises its own goals and behaves accordingly — complicates our understanding of what it means to be alive. But does it serve a scientific purpose?

I said ~5% of ASLO 2026 attendees were on Bluesky. Real number is closer to 11%. Google misses profiles with custom handles like @water-rox or @drdaphnia or @biogeojem. The Bluesky API doesn't. 29 → 168. Apologies, limno crew. #ASLO2026. docs.google.com/spreadsheets...

trying to ways to recover missed handles: keeps candidates whose displayName or description matches the affiliation/topic Scrape limnology/aquatic-science starter packs — Bluesky has curated lists like "AquaSky" / "Limnology" / "Ecology" packs with hundreds of scientists pre-vetted.

Erika C. Freeman @ecfreewoman.bsky.social · 05/05/2026
Partly my crawl, but it seems ASLO/limnology hasn't migrated to Bluesky the way some biomedical or ML fields have, so even after correcting for my undercount, LinkedIn still beats Bluesky by roughly 8:1 for ASLO-SIL crowd

Erika C. Freeman @ecfreewoman.bsky.social · 05/05/2026
I'm trying to find the aquatic-science crowd on here ahead of ASLO 2026. Out of 1,555 attendees, only ~5% are findable on Bluesky vs 43% on LinkedIn. If you're a limno/biogeochem/DOM person, please wave. #ASLO2026 #limnology

Urban parks enhanced immediate functionality but reduced genomic size and evolutionary flexibility, suggesting that urbanization pushes microbial communities toward functional specialization at the expense of adaptive capacity. 🧪🌐🦠🧬 www.nature.com/articles/s44...
