Bluesky has definitely slowed over the last few months. Only ~110 #zebrafish fans joined over the last nine months. I understand people going to other platforms (LinkedIn is nice) but dumbfounded by those that went back to Twitter/X. To support that vile content for random/bot engagement? smh 🤦♂️
Want to know how much the Bluesky #zebrafish community has grown? We now follow half as many shoal members compared to the peak of Twitter (2.2k).
If you work with cool teleost models in biomedical, developmental or evolutionary research, we want to follow you! Reach out if this describes you 🙏 🧪

Really enjoyed this imaging spotlight by @focalplane.bsky.social. The transgenics are 🔥!
Our latest ‘Imaging spotlight’ is from Jan Brugués @brugueslab.bsky.social & Alison Kickuth @alisonkickuth.bsky.social where they discuss the microscopy & microrheology techniques that they used in their research dissecting the mechanics of cytokinesis.

I always wanted to attend this conference while I was in Nebraska but I always had another conflict. Do try to attend if you are in the region or even outside of it! Midwesterners really are a friendly bunch 😊 You won’t regret it!
Save the date! The organizers of the Midwest Zebrafish Meeting would like to personally invite you to attend their next gathering, which will be held June 24–26, 2026, at the Van Andel Institute in Grand Rapids, Michigan. Check out this thread for more details about the conference!👇 #zebrafish 🧪

This is amazing news! And I just heard BioEYES is coming to Kings College London as well 👀
BioEYES is growing its impact globally. With new support, the hands-on science program that introduces students to biology through zebrafish is launching in Accra, Ghana. @bioeyes.bsky.social magazine.krieger.jhu.edu/2026/02/bioe...
BioEYES program expands to Ghana - Arts & Sciences Magazine
The BioEYES program, which brings live fish into classrooms to teach the fundamentals of biology and boost interest in science, is starting in junior high schools in Ghana.

This is not limited to #zebrafish but includes all organismal research. If you can spare 15 minutes, you may help safeguard the future of responsible animal research in the UK. 🙏
As the political climate around animal research becomes less supportive in the UK, it is our interest to argue for & protect organismal biology.
BBSRC opened a survey, which gives us a timely platform. Please fill & share link among colleagues. Deadline: 9/2

It's been 10 years since I came up with the idea of @zebrafishrock.bsky.social & a lot has changed personally. I take the small victories regarding better mental health & a more resilient work-life balance. I can't say how much longer I'll run the account but I'm in a much better place since then. 😊

I hardly watch TV but there’s so many commercials about over-the-counter drugs in the US! I suppose if you feel sick in the UK, you just go to the GP rather than self-medicate.

Made it to Nebraska after 21 hours of travel (Bristol 🚘 London ✈️ Atlanta ✈️ Omaha). With ageing parents, I understand why family don’t want to make the trip anymore. Now if only I didn’t wake up buzzin’ at midnight local time, it’d make my life easier.

Well, it's official. I've finally changed the proofing language in Word to 'English - United Kingdom'. With pronouncing zee-brafish as zeh-brafish, I've fully acclimated to British culture. (No, my accent hasn't changed 😆)

#KnowYourZDM was my (albeit failed) attempt at a collaboration with ZDMS. As a result of my insistence that @zebrafishrock.bsky.social be a pan-zebrafish society forum, most of the societies stay clear of us. 🤷

I used to get imposter syndrome when sharing other people’s stuff for #ZebrafishZunday. I got over it by thinking that if more people (whether it be a friend, family member or even a grant reviewer) see an awesome image and think zebrafish are cool, it collectively makes our lives/research easier.
