@michaeltconnelly.bsky.social et al. sequenced 342 Pocillopora coral samples from the Eastern Tropical Pacific, revealing four distinct species; algal symbiont community profiling identified dominant symbionts that varied according to host species. 🔗 doi.org/10.1093/gbe/evaf235 #genome #evolution

Last postdoc pub finally out!! This one was a doozy, but really enjoyable to work on. Involved some creative problem solving in regards to analysis of transcriptomic data from complex experimental designs. In the end I learned A LOT from this team and think the final product is pretty cool.

#ProtistsOnSky no 'swimming' by 𝘝𝘢𝘮𝘱𝘺𝘳𝘦𝘭𝘭𝘢, definitively no 'staying still'. just a relaxed walk towards the lunch...

Els coralls dormen com nosaltres, però la seva simbiosi no descansa 🪸 📕 Un equip de recerca de l’ @ibe-barcelona.bsky.social ha descobert que els coralls descansen a la nit tot i no tenir sistema nerviós, mentre que els seus microorganismes continuen actius. 💤  👉https://shorturl.at/wC0eU

Cool web story on our diel coral research! Check it out here: shorturl.at/qx9K6

✅ For the first time, it has been observed in situ that "sleep" helps maintain the host-microbe balance in very primitive organisms, a mechanism that could be extremely ancient in animal evolution.

🌙 When the sun sets, corals recover from the stress accumulated during the day, caused by the intense activity of their symbiotic microorganisms. 💤 #DiscoveringLife #ConservingBiodiversity 👉https://doi.org/10.1016/j.chom.2026.01.004

Corals sleep like us, but their symbiosis does not rest🪸 📕 A research team from the @ibe-barcelona.bsky.social has discovered that corals rest at night despite not having a nervous system, while their microbes remain active.🧵 #UnravellingEvolution 👉https://shorturl.at/qx9K6

🚨New Pub Alert🚨 We present a system-level molecular framework of natural diel regulation in the stony coral P. strigosa, integrating host & symbiodiniaceae transcriptomics with microbiome dynamics over 6hr intervals. Amazing to publish this PhD work @miamirosenstiel.bsky.social 👉 shorturl.at/TzYEr

A lot of great discussion at @univmiami.bsky.social IDSC Day 2026 about advances in AI & Machine Learning- including critical ethics issues. Presented our newest work adapting protein language models (PLMs) in corals to enhance functional annotations. Thanks for hosting such an awesome event IDSC!

Emergency sampling in the USVI as part of our NSF Diadema project. Didn’t even know I was coming down here yesterday at breakfast; today flew down, and was in the water within 45 mins of arrival. Unfortunately, it’s happening at our site (but this is good for our study). Urchins are dying…

Out now in Environmental Microbiome! 🧬 By re-analyzing microbialite sequencing data, we show that chromerid algae (the closest photosynthetic relatives of apicomplexans) are consistent and widespread associates of microbialites across diverse marine and freshwater environments worldwide 🌎

Emergency for Caribbean collaborators: There appears to be Diadema mortality somewhat reminiscent of the 2022 die off occurring right now in the USVI. If anyone hears of wider occurrences in the region please let us know! Please re-post!

New preprint out! Using ~75k environmental OTUs + 77 fossil calibrations, we reconstructed a Proterozoic timeline of eukaryote evolution. Our results show crown eukaryotes were already diversifying >1.6 Ga, long before the first undisputed fossils (~1.05 Ga). 🔗 DOI: www.biorxiv.org/content/10.6...

🧪 Dr. Emily Aguirre's final dissertation chapter is published! She isolated a putative bacterial symbiont then cocultured it with axenic algal symbionts to ask how it impacted growth and gene expression - results were unexpected but do support a beneficial relationship - read more here rdcu.be/eUKQz
