Millions of beating cilia keep airways clean. At the base of each is the transition zone (TZ), a gate that controls which proteins enter and leave. In our paper out today in Science, we used cryo-FIB-ET to image the TZ inside human airway cells www.science.org/doi/10.1126/...

In situ structure of the human ciliary transition zone links linker defects to primary ciliary dyskinesia
The ciliary transition zone (TZ) regulates ciliary proteome composition, yet its molecular architecture, protein content, and contribution to motile ciliopathies remain poorly defined. We applied in situ cryo-electron tomography and subtomogram averaging ...

Workshop announcement graphic shows a classroom scene with the CryoSPARC logo and workshop title, date, and hosting organizations (SickKids and Structura Biotechnology)

Workshop information:
As part of the Canadian Cryo-EM Nexus, The Hospital for Sick Children (SickKids) and Structura Biotechnology are pleased to announce a two-day CryoSPARC workshop:

Beyond consensus refinements: Advanced cryo-EM data processing with CryoSPARC

at SickKids in Toronto on September 24-25, 2026.

Led by experts from Structura, this workshop offers a unique opportunity for participants who already have a sound understanding of cryo-EM and substantial CryoSPARC experience to deepen their skills and become a key resource for cryo-EM image analysis within their institutions.

There is $115 (CAD) charge to partially defray some of the costs of running the workshop, which is sponsored by SickKids and Structura. Attendees will need to bring their own laptop computer and arrange for travel and accommodation.
Please apply before July 24, 2026 using the following link:
