Sheep and pig #gastruloids, @IftachN: www.biorxiv.org/content/10.6...
The accumulating knowledge of the relationship between #SCBEMs and #Embryos, allow us to learn about species similarities and differences in gastrulation and body plan elaboration.

@amartinezarias.bsky.social Agree, and a fun fact I learned from Julie Baker (Stanford)...Da Vinci got it wrong because he didn't find access to human developmental biology! πŸ€”

Happy to share this work from Carlos Camacho de la Maccora that reveals how rates of posterior progenitor addition and anterior vacuolation are balanced across the notochord. With Alberto Ceccarelli and @osvaldo-chara.bsky.social we present a model of long-range communication to provide robustness.

Very interesting and thorough discussion of the history and challenges of the #genotype -> #phenotype mapping.
A genetic approach, of course. Are we missing something in that 'missing #heritability'?

The Upgrade of a Mother’s Brain The brain of pregnant women undergoes profound plastic changes that will impact herself as well as her newborn. Here is a deep dive into this important, fascinating, and often misunderstood process.

Very sad news. Gail Martin (1944-2026) was a figure in developmental biology. She pioneered the field of ES cells.
A great colleague, a friend and a lovely person.

Reading this, ST Coleridge had a comment "The history of man for nine months preceding his birth would, probably, by far more interesting, and contain events of greater moment, than all three score and ten years that follow it."

"surely we are all out of the computation of our age, and every man is some months elder than he bethinks him; for we live, move, have a being, and are subject to the actions of the elements, and the malice of diseases, in the truest microcosm, the womb of our mother”

I agree--reading this book was one of the influences that shaped my career. I also wore out a copy writing this piece about its influence. HIGHLY recommended πŸ§ͺ

Thanks but I am not clear what you make of the claims of the paper (which I still need to look at). Is there anything really new? I find it difficult to believe some of the claims of the press. And of course, the only blueprint in a genome is for another genome.

For anyone interested in the history of molecular biology, I cannot recommend Judson's The Eighth Day of Creation highly enough. One of the great book on the history of science.

I have two copies because a actually wore out the first one (paperback)

Sort of agree. They make a good point raising the problem but when it comes to provide a path out, they're not as forward as I'ld liked The secret is in the cell #MasterBuilder We need a true evolutionary theory from the cell perspective to COMPLEMENT not to substitute the gene's eye view of life

Needless to highlight what I think about this. As underappreciated as it is important #Wntch the way cell populations coordinate and balance cell fate decisions

Seriously, preprinting means your science is accessible to everyone, virtually immediately. No paywalls. Sunlight is also a disinfectant and the number of sloppy preprints I've encountered is tiny.

We now live in a world where lies from authorities have become the norm, and its tough to navigate. At UNC we're currently navigating a new rule from the State BOG mandating that all syllabi be public information. This raises many concerns but my current issue is a set of lies we were told 1/n

Point of no returns: researchers are crossing a threshold in the fight for funding With so little money to go round, the costs of competing for grants can exceed what the grants are worth. When that happens, nobody wins.

Seriously folks we crossed this point some time ago in many fields of research.
