Listening to David Lammy on @BBCr4today attempting to justify abolishing trial by jury, it is increasingly and terrifyingly clear that he simply does not understand the issues.

As set out in this thread, the causes of the court backlog are chronic lack of funding and absurd inefficiency. The government has made no proposals to address either. Their answer is to remove juries. Rather than fix the leaking roof, their solution is to burn the house down.

Fun collaboration! All the nitty-gritty about N2B27 and gastruloids. Kudos to all the authors, particularly Tina Balayo (¡que va de primero!)

There's increasing evidence that in organoid/embryoids conditions of cells at start of experiments is crucial/ determines outcome. Much to be learnt still. Taking advantage of mouse #gastruloids, two groups explore this here. Important work to calibrate the field www.biorxiv.org/content/10.1...

Great preprint out from the MicroAge team in @livuni-ilcams.bsky.social! www.biorxiv.org/content/10.1...

Excellent work supporting #modularity of the mammalian #embryo, a role for #hypoxia & how development exploits these features. It shows what we can learn from assemblies of #gastruloids @ spatio-temporal coordination of the modules in AP organization. Putting modules together, extremely informative

Aydan Bulut-Karslioglu@bulutkarslioglu.bsky.social · last yr.

⚠️ I am really excited to share the work of Anastasios Balaskas, an excellent PhD candidate in the lab, with the wider world. Tasos made a significant advance: generating a stem cell-based embryo model that contains both posterior and anterior neural tissues of the late-stage gastrulating embryo.

This was a fabulous collaboration! Thanks @gastruloids.bsky.social and to Suad and Huei who worked incredibly hard to make it happen!
