The lab is proud to have contributed to the first chromosome-level sea spider genome! Many thanks to Niko Papadopoulos, Georg Brenneis, and Andi Wanninger, who spearheaded the work! #pycnogonida

It’s an honor to have taught the arthropod module at Woods Hole Embryology! I started my daddy-long legs system at Woods Hole as a student when I took the course 16 years ago. What fun to be invited back to teach students to inject spiders and arachnid embryos! Added bonus: Gui Gainett and Limulus!

The lab is delighted to release the first comparative analysis of the arachnid orders Opiliones and Solifugae, using chromosome-level genomes! We look at macrosynteny as a phylogenetic character for resolving chelicerate phylogeny.

A new review paper from the lab—fun times with sea spider and daddy-long legs embryos!

Excited to share our recent review on extraembryonic mesoderm development, just published in Development!

"Extra embryonic mesoderm during development and in in vitro models."

📢New paper in @royalsociety.org Proceedings B!📢

We tracked #eye #development in seven spider species with wildly different visual systems to try and identify the mechanisms underlying their diversity 👀👀👀👀

Microtubules still doing their thing in an early ascidian embryo (Phallusia). Thanks to the Ascidian BioCell Team

Friday is Phalangium day!

marine embryo (ascidian/Phallusia) making a gut (gastrulation)...thanks to the Ascidian BioCell Team. Cell contours are blue, microtubules that separate the chromosomes are magenta

Interested in rare genomic changes and arachnid phylogeny? Check out our preprint here! We’re taking a look at the architecture of Solifugae and Opiliones genomes.

The lab was delighted to host Professor Eileen Hebets, the John T. Emlen lecturer this year! For more on her fantastic work on spider songs and dances, please visit hebetslab.unl.edu.

The lab is delighted to release the first genome for the giant American vinegaroon! The slowly-evolving order Uropygi captures the strongest signature yet of the arachnopulmonate whole genome duplication. #biodiversity #genomics

If you’re ever feeling down, Anoplodactylus has your back.

Very excited about the publication of this review with my dear friend and colleague, Efrat Gavish-Regev!

A scorpion embryo to brighten your day.

Purple: Pax2A. Yellow: Pax2B. Blue: nuclei.

I’m mesmerized by Japanese sea nettles.

Please add? I work on arachnid phylogenomics and comparative development!

Olfaction in spiders. We found that the wall pore sensilla in spiders look similar from the outside to those of insects, but differ ultrastructurally in various ways. Independent evolution!

Let's take a look #UnderTheScope! 👀 🔬 This is an adult Nematostella where stinging cells are labeled with eGFP (green). The Gibson Lab studies these to understand #evolution. (@gelatinoussting.bsky.social) #EvoDevo #CellBiology
