Amoeba Discovery

Andy Chandler-Grevatt sitting at a table with piles of Moss Safari books. He is signing one of them. There are stickers, badges and bookmarks on the table in front of him.

A box of books called Moss Safari

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.

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

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!

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 🦑

If you can't be with the forams you love, love the forams you're with #Ammonia

#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.

🔬Over a century ago, Gulielma Lister used her stunning illustrations to bring attention to slime molds—long before they captured the imagination of today’s photography community.

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...

Found out that our publication on the differential abundance of corallicolids in P. clavata was a #TopViewedArticle in Environmental Microbiology last year 🙌 #Protists #Corals #ClimateChange

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

Happy birthday! 🥳 My birthday is tomorrow! 🤓

When the day is grey and rainy, the best kind of inspiration comes from old taxonomic books filled with beautiful illustrations. Here’s a plate of slime molds by Ernst Haeckel published in 1904 – a timeless blend of art and science. 🧪📖🔬

Comparative Genomics Supports Sex and Meiosis in Diverse Amoebozoa Abstract. Sex and reproduction are often treated as a single phenomenon in animals and plants, as in these organisms reproduction implies mixis and meiosis

Another paper: doi.org/10.1093/gbe/...

Sexual reproduction is a poorly studied phenomenon in protists. There are several primitive forms of sexual reproduction, making it difficult to determine when they reproduce sexually and when asexually. Testate amoebae are a good example of such a case.

@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.

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...
