@nicolasrivron.bsky.social and I look to recruit a postdoc through the VIP3 rogramme to investigate post-implantation development of blastoids. Contact us if you are interested, and let your colleagues who could be interested know!

I'm now on Bluesky!🤗 Excited to share our preprint, reviving Kristy Red-Horse's interest in the placenta from her PhD ~20 years ago! We find using 3D imaging that the mouse placenta is far more invasive than previously thought. Furthermore, we find a surprise from our favorite chemokine CXCL12...🧵:

Hi all! 👋 leeboratory.bsky.social and I are recruiting a VIP³ postdoc to join our teams and decode the genetic logic of how blastoids transit to the post-implantation stage. MolBio, genetics and computational approaches. If this sounds like you (or someone you know), we’d love to hear from you! 🚀

Watson was deeply influential to me as a genomicist, but not how you may assume From stealing Rosalind Franklin's lab notes to his frequent sexist & racist bioessentialist comments later in life, he showed how the scientific community would still worship a terrible person Don't idolize bad people

The ethical framework for embryo models needs clarity and simplicity. The spirit of the integrated/non-integrated distinction was to more prominently regulate models that could potentially develop into a fetus. Hafez Ismaili M’hamdi discusses this. www.progress.org.uk/complexity-w...

Properly understood, the integrated/non-integrated distinction was not just a technical shorthand for the presence or absence of particular tissues.

Have you ever wondered how your back formed? The human embryo makes a neural tube (future spinal cord) and somites (trunk muscle/bone) from ~d20. They’re formed at the same time and place, so we used human Trunk-like Structures (hTLS) to investigate their ‘co-development’… (1/7)
