We're excited to share with everyone a preprint of our manuscript that resolves the cellular origins of the symbiosome in cnidarian-algal symbiosis through proteomics of the symbiosome, RNAi, and CRISPR/Cas9 experiments. ⬇️

Unfortunately it looks like we won’t be hitting the preorder minimum for these hats unless we get some more orders!

So if you’re interested in a leafcutter ant hat or are considering holiday gifts, please preorder! 🐜🌿

Available below ⬇️

Happy Ctenophore Day!
These glowing ocean drifters look like jellyfish but aren’t! They’re comb jellies, shimmering creatures that light up the sea with rows of beating cilia 💙🌈
Which species can you identify? 👀 Most are raised in @pawelburkhardt.bsky.social lab

They have a huge size range from under a centimetre like these ones to over 40cm!
😂 maybe a scale bar for future then! We dont want the baby Fractos making you uneasy
This #FossilFriday we have wrapped up a wonderful field season in Newfoundland on #Ediacaran life - here are some tiny #Fractofusus for #FractofususFriday from Mistaken Point
Beautiful #Ediacaran fossil light on the E surface at Mistaken Point 🤩
This #FossilFriday we are wrapping up a fantastic week of fieldwork @discoverygeoparknl.bsky.social imaging their #Ediacaran fossils and thinking about what shapes early animal evolution. Thanks so much to Edith at the Coaker Foundation for looking after us so well
Beautiful day out @discoverygeoparknl.bsky.social admiring the tiny Fractofusus on the Johnson surface 😍
Fantastic being back in @discoverygeoparknl.bsky.social mapping out their wonderful #Ediacaran fossils 👌
Jenny stands on a fossil surface, about to image the surface to make 3d model of the surface. A Fractofusus and Hiemaloria from Discovery Geopark

📢 deeptime: an R package that facilitates highly customizable and reproducible visualizations of data over geological time intervals

🔗 doi.org/10.1080/2096...

Fully #openaccess in @bigearthdata1.bsky.social with insight about deeptime📦 development and code examples!

#rstats #geology #paleontology
Plot of global benthic δ18O data for 0 – 5.3 Ma (Lisiecki & Raymo, 2005) with geomagnetic polarity subchrons displayed on the top x-axis and planktic foraminiferal primary biozones plotted on the bottom x-axis using the deeptime package. A mammal phylogeny (Garland et al., 1992) plotted in the fan layout using the ggtree and deeptime packages. The greyscale concentric circles in the background indicate geological stages, whereas the linear colored timescale indicates geological epochs. Early tetrapod occurrence data (Jones et al., 2023) plotted as a taxonomic/biostratigraphic range plot using the geom_points_range() function from the deeptime package. A stratigraphic column of Cretaceous lithostratigraphic units from the San Juan Basin, USA. The deeptime package has been used to add pattern fill which indicate the primary lithologies of the units as reported by the Macrostrat API (Peters et al., 2018) via the rmacrostrat R package (Jones et al., 2024).

Our paper on the genetics of guppy color patterns has now been assigned an issue in NEE: doi.org/10.1038/s415...

With this paper, we also publish all 14,100 guppy photos used in the study, including before and after alignment and ornament extraction:

¡Qué lindo!

Every bit of this south wall in the #MarDelPlataCanyon is vibrant and alive. Read and imagine how a tiny sponge larva or other stationary animal finds a home in a place like this: www.instagram.com/reel/DN37jxs...

Let’s take a deep dive into chemoautotrophy!

Dr. Roxanne Beinart, Associate Professor of Oceanography at the University of Rhode Island, joins the #QualityQuorum to discuss how some marine creatures use bacterial symbioses to provide organic compounds for growth and reproduction.
