Interested in how cells use genes to create shape, form and function in #embryos as well as in Societal Wellbeing

Curious. Over the last 100 years #longevity has pretty much doubled w little research input, while #fertlity decrases dramatically and yet, all the hype and the funding goes into treating aging as a disease and there is little research and funding for #ReproBio.

Looking forward to my visit to Fac Biologicas @ucm.es (biologicas.ucm.es) in #Madrid, my alma mater, where I studied (and dreamt) 50 years ago!

You have a great, important and much needed initative (www.humanreproduction.uzh.ch/en.html) in an area that needs more attention and better funding. #HumanReproduction requires a bridge between #DevBiol and #Gynecology, as Bob Edwards built.

Can't help but sharing this thought on #Genetics from A. Garcia Bellido (1936-2025). His legacy runs deep through the work of his disciples and readers but it is there.

In 2009 A.Garcia Bellido asked me to try my hand at a history of #Genetics in Spain. With some reluctance (I am no historian, nor pretend to be one), I obliged ijdb.ehu.eus/article/0828....
He helped me with many conversations and, of course, he had to have a place of honour in it (see Appendix I)
A perspective on the development of Genetics in Spain during the XX Century | The International Journal of Developmental Biology
At the beginning of the XXI Century, Spanish Biology lives a period of unprecedented growth and development. This situation owes much to the stability of the last few years and breaks a pattern in which Science was the activity of a few self-taught individuals working within an indifferent environment. The development of Genetics is a good example of these factors. A long isolated period dating back to the 1500s was broken at the beginning of the XX Century through the creation of a number of institutions and, in particular the Junta de Ampliacion de Estudios, which created a seed for scientific development and had a significant effect in the area of Genetics. However, the Spanish civil war destroyed this seed and forced a new beginning. Throughout the second half of the century, steady progress, largely driven by individuals formed abroad and returning to Spain with knowledge and methods, has been the basis for the establishment of a scientific ingrastructure from which Spain is making important contributions to modern biology. The person of Antonio Garcia-Bellido has emerged over the last 40 years as a reference for modern genetics and also as the root of an important, perhaps the only, real school in this area of work.

Thank you www.humanreproduction.uzh.ch/en.html specially @cavazzalab.bsky.social for two days discussing the science, ethics and history of #HumanReproduction. An impressive and much needed multidisciplinary intiative.

The passing of A. Garcia Bellido
es.wikipedia.org/wiki/Antonio...
means another pioneer of #DevBiol leaving the room. An impactful personality who could create an intellectual storm w/ a sentence.

We express our deepest condolences on the passing of Antonio García-Bellido, considered the father of the Spanish school of Developmental Biology and an influential figure in this discipline worldwide. For the #SEBD, his passing represents the loss of its founder and first president. Rest in peace.

Was truly a must to have @neilshubin.bsky.social visiting for a month as a guest Prof. @college-de-france.fr, spending time with colleagues, with lab members 👍 and delivering a superb series of 4 talks (see below)🙏. This is what science is about. I’ll miss the morning coffees ☕️🤘
