Today 🇨🇦 announced the 64 scholars recruited from top US universities for the Canada Global Impact+ Chairs. They sounds like great scientists. But the enormous level of funding funnelled to this program is jaw-dropping when compared to the pitiful success rates at CIHR.

Due to my role at the Terry Fox Research Institute I no longer comment publically on CIHR but this largest funder of Canadian health research made an important statement today: cihr-irsc.gc.ca/e/54795.html and I can’t just watch this beloved agency crash.

What we heard: Strengthening the long-term sustainability of the Project Grant program - CIHR

The purpose of this phase of our engagement has not been to make or announce decisions. It has been to build a shared understanding of the pressures facing the system and to hear from applicants, reviewers and institutions on possible interventions and their implications.

Definitely a legend! It had been a privilege to learn so much from Jim while I was doing my post doc next door.

Legendary myosin researcher Jim Sellers retires after many years of making significant contributions to the field and being an unfailingly generous to colleagues - alway sharing materials, insights and wisdom. A symposium honoring Jim will be held in Sept. www.nhlbi.nih.gov/events/2026/...

Excited to share our new paper, now published in Nature Cell Biology! 🎉 We asked a fundamental question in cell biology: How do cells maintain polarity while migrating? Especially how do cancer cells navigate confined spaces? www.nature.com/articles/s41556-026-01981-1

CD44 restricts EGFR mobility to polarize cytoskeletal signalling modules driving bleb-based migration - Nature Cell Biology

Jha et al. show that the transmembrane protein CD44 restricts EGFR mobility to maintain an EGFR–PI3K–Rac gradient during bleb-based cell migration.

Exciting to see this out in its final form! Wonderful work led by @probablycarmen.bsky.social. Want to know why protrusions are better at initiating immune signaling in #Tcells? Look no further. Link to Carmen’s 🧵 on the preprint bsky.app/profile/prob...

Revised role for actin-rich protrusions in T-cell activation: @franbottanelli.bsky.social @probablycarmen.bsky.social et al reframe them as sites of enhanced receptor activation by exclusion & clustering dynamics, rather than pre-enrichment of signaling components link.springer.com/article/10.1...

Have you ever heard that women have more chances than men of getting grants or positions in academia? Of course you have, and here are my personal views on this. With the shocking revelation that no, it is NOT TRUE ! (1/n)

We look forward to hearing feedback from the community on our #preprint where we used #NETosis as a platform to show that chromatin decompaction inside the nucleus directly regulates cell mechanics. This work identifies long-range biophysical impacts of chromatin in mammalian cells.

Chromatin is a long-range force generator that regulates plasma membrane tension and cell integrity independently of gene expression https://www.biorxiv.org/content/10.1101/2025.10.02.680155v1

If you're interested in biophysics in the context of infection and immunity, we're looking forward to seeing you at the ASCB/EMBO meeting.

Effie Bastounis@effiebastounis.bsky.social · last yr.

Thrilled to organize the “Physical Cell Biology of Immunity & Infection” subgroup at Cell Bio 2025 – ASCB/EMBO with @hawa-racine.bsky.social, @jaumouillelab.bsky.social, Marcus Taylor & Shalini Low-Nam. Seeking exciting interdisciplinary speakers! Abstract deadline: Sept 3 www.ascb.org/cellbio2025

Comment on our @Reproducibility project in @Drosophila immunity. It is a normal that findings—however exciting and important at the time—may later prove to be more complex than initially believed. Re-evaluations is essential to the self-correcting nature of science. www.science.org/content/arti...

Majority of fruit fly immunity studies can be replicated, huge analysis finds

Verification of 50 years of data bolsters immunology research, but identifies “suspicious” papers that don’t hold up

Latest from @ivaskalab.bsky.social @jrwconway.bsky.social in NCB. We find that SHP-2 inhibition stops TNBC invasion and limits metastasis by blocking integrin dephosphorylation! Read more at: www.nature.com/articles/s41...

Dynamic regulation of integrin β1 phosphorylation supports invasion of breast cancer cells - Nature Cell Biology

Conway et al. show that integrin β1 phosphorylation is regulated through balanced activities of tyrosine kinases, such as Src and Arg, and phosphatases, such as PTP-PEST and Shp2, facilitating invadop...

Somehow, I only started to realize this while I became a faculty member. Although, I wonder whether having a better awareness of these challenges would have been discouraging.
