An amazing day, I was 17 and lived about 5 min away from Checkpoint Charlie!
The Berlin Wall, which divided Berlin and Europe for 28 years, fell on 9 November 1989.

Very sad news indeed…
John Gurdon, former Group Leader and Head of @cellbiol-mrclmb.bsky.social has died.
Despite calling himself a "total non-intellectual” his work to reprogramme somatic cells to pluripotent stem cells transformed the field of developmental biology.

We cannot provide invoices at present but are working on a system to do so in the near future. However, you will receive a receipt for your tax-deductible donation. Large teams of people work to keep FlyBase going, and the need is great, so please donate generously.

Flybase is free to use but not free to make. It takes large teams of people and millions of dollars a year to create the knowledgebas and tools for fly research. Please donate generously.
FlyBase needs your help! We ask that European labs continue to contribute to Cambridge, UK FlyBase, whereas US and other non-European labs can contribute to US FlyBase. For more information and how to donate: wiki.flybase.org/wiki/FlyBase...

For something as classic as the Spemann-Mangold organizer first discovered in amphibians, the existence of such an organiser in mammals remains elusive. In this thought provoking review by Kate Mcdole et al, they discuss the evidence for and against such organiser in mouse.

European Fly PIs: please respond to the email we sent out yesterday and help save FlyBase!
We currently have a call for support that has gone out to European labs, to support FlyBase-UK. We are asking our colleagues from labs in the US and other countries to wait for a similar call to them that will go out in the near future, to support the US sites. We thank you for your patience.
URGENT: FlyBase has lost practically all its funding overnight; even user fees are tied up in denied grant funding. 🤬🤯

This incredible community, on whose backs our #Drosophila labs depend, can't be left out to dry.
