I'm very excited to finally share the main work of my PhD! We explored the evolutionary dynamics of gene regulation and expression during gonad development in primates. We cover among others: X chromosome dynamics (incl. in a developing XXY testis), gene regulatory networks and cell type evolution.

This week we are bringing you MBARI: From the Vault. We’re sharing content curated by the team of experts responsible for our video archive. Get the inside scoop on some of the most interesting and unique observations they’ve made over the last few decades!

A great article highlighting the broader implications of the three parallel recent papers from our group and our wonderful colleagues in Spain and Belgium...

Maria Sibylla Merian, naturalist and scientific illustrator, was born #OnThisDay in 1647. She collected insects and raised silkworms as a girl, and was one of the first naturalists to observe insects directly and document metamorphosis.

The beauty of embryogenesis. Can you see the blood flowing in rhythm with the heartbeat? #sharkembryo 🦈

openRxiv has arrived! We’re thrilled to announce the launch of openRxiv as an independent, researcher-led nonprofit to oversee bioRxiv and medRxiv, the world’s leading preprint servers for life and health sciences. openrxiv.org/introducing-... #openRxiv #OpenScience #Preprints #bioRxiv #medRxiv

How does gene regulation shape brain evolution? Our new preprint dives into this question in the context of mammalian cerebellum development! rb.gy/dbcxjz Led by @ioansarr.bsky.social, @marisepp.bsky.social and @tyamadat.bsky.social, in collaboration with @steinaerts.bsky.social

The revised version of our #Platynereis #connectome paper is now out: https://elifesciences.org/reviewed-preprints/97964 Cell-type-level annotation of the whole organisms, including synaptic and desmosomal connectomes. Can be explored with CATMAID here […] [Original post on biologists.social]

So excited to announce that our study on the development and evolution of pallial cell types and structures in birds, led by @bassi-z.bsky.social, is now out in @science.org! www.science.org/doi/10.1126/...

This paper provides now solid evidence that the xenacoelomorph male gonopore is homologous to the bilaterian hindgut. www.biorxiv.org/content/10.1...

@stevestuwill.bsky.social you posted on 𝕏 on Dec 5, 2020 this stunning video - why not repeat on 🔵bsky ? (sorry, I did)... "Time-lapse footage of a vampire amoeba: a microscopic organism that feeds on algal cells by breaking through their cell walls and sucking out their insides." #ProtistsOnSky

Just a gorgeous #Purkinje neuron all by itself in the cerebellum. Only with #lightsheet #microscopy on a whole #cleared sample could you ever hope to catch a lone reporter expressing cell in it’s entirety. #science 🧪

For my first post on 🦋, I am incredibly excited to share that my PhD paper has been published in #ScienceAdvances! We compared the development of the anterior neuroectoderm to uncover how the chordate #forebrain evolved 🧠. Have a look at the summary 🧵 below! www.science.org/doi/10.1126/...
