New paper on diatom phylogenomics from our lab. Ten years in the making, but it always took a backseat to student and postdoc papers.

Load a Newick file and intuitively add/remove/resize branches.
Useful for quick conceptual trees, extracting subtrees, or turning ideas into Newick.

Conserved genetic markers reveal widespread diatom sexual reproduction in the global ocean - Nature Communications
Diatoms dominate the oceans, yet sexual reproduction - key to bloom dynamics and species evolvability - is rarely observed. Using a lab-to-field approach, this study presents conserved markers applica...

The amoeba Difflugia bacillifera builds its shell from things that contain silica, and it is not particular about the source. These ones have incorporated whole shells from another testate amoeba (Euglypha), along with diatoms, algal cysts and chunks of rock. #Amoebae #ProtistsOnSky #peatlands

Recent MDPI paper including diagram of a bacterial cell with a mitochondrion 🤦‍♀️ The authors propose a mechanism for the toxicity of silver nanoparticles: "Ag+ ions in AgNPs bombard the bacterial mitochondria’s electron transport chain, resulting in cell death".

The buff-tip moth (Phalera bucephala) has mastered a very particular kind of camouflage.

When they close their wings up, they resemble a broken twig.

Native to large parts of Europe, there's regional pattern variation that reflects the local tree species. This one best resembles birch twigs?

Many amoebae incorporate diatoms in their shells, but Cylindrifflugia bacillariarum is the master. Third and fourth pics are close views of the glue that holds it all together. #ProtistsonSky #Amoebae #Peatlands

Dear @bsky.app, please let @atrupar.com keep posting so we don't have to go to the bad place to see his much needed videos.
lol Bluesky still has a daily video upload limit? Well, I guess I'm done here for the evening. Any help on this @pfrazee.com? Trump is currently being interviewed on ABC but I'll have to take my coverage elsewhere.

I lost my job at the National Science Foundation yesterday, along with 167 of my colleagues, including some dear friends. This was the best job I've ever had, and I thought it would be my last. The PI community has been sympathetic and supportive, without exception. I will miss working for you.
