Mystery Radiolarian? - Found this in a sample from the south Pacific about 10 years ago - Still asking if anyone knows its name? #protistsonsky

Very excited yesterday when a box of Moss Safari books were delivered! So today was signing the complementary copies with some added Moss Safari goodies to be sent out to those who helped me with the book. Available from pelagicpublishing.com/products/mos... and book shops. 25% off code: MOSS25

Evidence for #recombination, and maybe #meiosis, in free-living #Rhizaria! I wish the results were clearer. As so often we raised more questions than we could answer :) If you are into #sex and the #meiosis-toolkit, this is an important read! #ProtistsOnSky link.springer.com/article/10.1...

Eleutheroschizon duboscqi is a marine protococcidian that parasites the polychaete Scoloplos arminger🪱 . It grows epicellularly, enclosed in a two-membrane parasitophorous sac derived from the host cell, that ends in a protein-rich tail #Midweekmicrobe 📷 Valigurová et al. 2015

Why do some planktonic protists develop a gelatinous matrix? We suggest that this original adaptation is a strategy to cope with ocean oligotrophy: doi.org/10.1111/1462... Led by @n-llopis-m.bsky.social, and thanks to all co-authors, I'm very happy to finally see it out! #protistsonsky

This is the first time I’ve seen a starfish larva in samples from Cromer Pier, so I’m super excited. This is probably Asterias rubens and this is a bipinnaria stage larva. I’ve photostacked the images, it’s not perfect, but it allows us to see all the bits of this very 3D larva. #plankton 🦑

#OTD in 1868 Elsie Sexton was. Born Alice Wilkins Tring, Elsie studied at the Truro School of Art before moving to Plymouth. Through her husband, Louis, she met Director of the MBA Dr Edgar Allen and began illustrating for his scientific publications, eventually publishing her own research in 1908.

Differential apicomplexan presence predicts thermal stress mortality in the Mediterranean coral Paramuricea clavata

An analysis of the microbiome of the Mediterranean coral Paramuricea clavata reveals that its microbial community, specifically microeukaryotes, plays a crucial role in its response to thermal stress...

First study from the lab is out! We describe ApuRs, a new family of microbial rhodopsins unique from apusomonads. ApuRs represent the first anion-conducting rhodopsin channels that can be controlled by UV light, offering potential as new optogenetic tools. #protistsonsky doi.org/10.1101/2025... 👇

@zlatogursky.bsky.social, a leading researcher of heliozoans, shared a gem in a recent exclusive interview: these underrated protists have a rare trait that could open doors in broader biological research. Don’t sleep on the heliozoa. 🔬🧪 #protistsonsky #microsky #evosky #mevosky

It was a very productive week in lab! We now have Naegleria fowleri (brain-eating amoeba) cultures growing, in addition to the Naegleria gruberi (harmless relative) cultures we have been using as a model. Put side-by-side, it is impossible to tell them apart.

🧪 Here’s a quick breakdown of the general structure of testate amoebae — from their shell to the pseudopodia they use to move and feed. You can read the full article on these protists in the first issue of Amoeba Discovery magazine: stefanluketa.com/amoeba-disco... #protistsonsky #systematics

@amoebadiscovery.bsky.social made an iteresting interview with me about #heliozoa and #centrohelids - I think these organisms are really important, understudied and gorgeous 😍 Also lots other intresting reading and beatiful pictures! #protistsonsky link: tinyurl.com/adiscovery1
