Check out this review on brain 🧠capillary ion channels in health and disease… a topic that has evolved (and continues to grow) dramatically over the past decade.🗓️📅

CIHR funding rate: 13.6%. Early 2000s: 30%+. Canada’s new $1.7B Impact+ program recruits talent — but without increased Tri-Council base funding, we risk further strain on an already stretched system. We’re calling for $1B over 5 years. Support here: tinyurl.com/33c5av46

Very pleased with our newest publication! In this study, we identify the Calcineurin-NFAT-DSCR1.4 signaling pathway as a druggable driver of capillary malformations caused by the GNAQ p.R183Q mutation, which is associated with port-wine stains and Sturge-Weber syndrome. 🔗 article: rdcu.be/e2gRC

We are looking for PhD students or Postdocs with an interest in developing and using new methods for functional genetics following our recent work 👉 rdcu.be/e05Oo and academic.oup.com/nar/article/52

Our paper on TCBE-Umax is out in @natbiomedeng.nature.com! We developed these high-efficiency cytosine base editors for zebrafish, enabling rapid functional testing of disease variants. This work is led by a talented scientist, Wei Qin. www.nature.com/articles/s41...

We’re delighted to see this out today! Latest work from the lab reveals insights into the evolution of brain immunity and the developmental and evolutionary plasticity of lymphatic endothelial cells. www.nature.com/articles/s41...

Couldn't be a better way to start 2026! Excited to share our latest publication. Tremendous effort by Rouf and coauthors to investigate how the zebrafish coronary network develops and interacts with the growing cardiac muscle. journals.biologists.com/dev/article/...

I cannot stress enough that you should not do this.

Check out our latest preprint on the cellular mechanical basis of Voronoi tessellations in epithelia! This biophysics study is inspired by disordered tessellations observed in zebrafish hearts 🤓🐟💙 #SulaimaanLim #ChiuFanLeeLab arxiv.org/html/2512.13...

It's not just social media. Looks like visitors to the US from Europe and other countries that are part of the visa waiver program will have to submit an enormous amount of data about themselves and their families, including DNA, if proposed new rules are accepted

🧠 An exciting fully funded 4-year PhD at the Universities of Edinburgh & Manchester with Drs. Ingo Schiessl, Audrey Chagnot, and myself! 📅 Deadline: Jan 9! 📝 Details are below 👇🏻 Please circulate this widely, thanks!

Bat shit crazy. US plans to start checking tourists social media. It will be "mandatory" to hand over the social media info, including email addresses & phone numbers used in the last five years, as well as the names, addresses, numbers, & birthdays of family members. news.sky.com/story/us-pla...

We are actively recruiting graduate students in behavioural & systems neuroscience. Please share with any talented trainees that are looking for a position!

Come join us in Heidelberg for the first German fish meeting 👩‍🔬👨‍🔬🧬🔬🐟🐠

When a larval zebrafish twitches its tail, the vascular endothelium lights up with a calcium signal, mediated by Piezo1. We used to think mechanosensing in endothelial cells was about sensing blood flow, but at least in this case it's about sensing body motion.

“By performing longitudinal live imaging of intubated adult fish we observe vascular regrowth and immune responses to [meningeal cerebrovascular injuries] over time in the same animal with unprecedented resolution” New work from #WeinsteinLab at NIH

Not sure why @lpachter.bsky.social did not post this here. But it is brilliant. Single cell genomics finally makes it to the clinic.

Thinking only of Rosalind Franklin today, and what was stolen from her (and so many other female scientists alongside her).

📅 Save the Date! The 4th Canadian Zebrafish Research Conference will take place on Friday, May 15, 2026, at CHU Sainte-Justine, Montreal (just before the Canadian Neuroscience Conference!) Multiple travel awards available with 2 Postdoctoral Rising Stars Awards! #izfs

I’m sure this guy is great, not the point, but to think the solution to Canadian scoence is to attract a few dozen scientists from abroad is complete nonsense. There are just as good scientists here. The problem is chronic underfunding. But this does not make headlines www.ctvnews.ca/health/artic...

BIG ANNOUNCEMENT📣: I haven’t been this excited to be part of something new in 15 years… Thrilled to reveal the passion project I’ve been working on for the past year and a half!🙀🥳 (thread 👇)
