On behalf of the International Union of Crystallography (IUCr), it is with immense excitement and joy that we cordially extend our warmest invitation to you to join the IUCr for the Twenty-Seventh Congress and General Assembly, set to be held in the magnificent city of Calgary, located in the heart of Alberta, Canada from August 11th-18th, 2026.

Calgary, a city renowned for its breathtaking natural beauty and warm hospitality, has been chosen as the host for this remarkable occasion. Nestled amidst stunning landscapes and boasting a rich cultural heritage, this vibrant metropolis promises to provide an unforgettable experience for all attendees.

For the first time in 12 years, IMC returns to Europe, bringing together more than 3,000 microscopists, imaging specialists, and instrument manufacturers from across six continents.

This promises to be an excellent meeting for structural biologists in general, and for electron microscopists in particular.

The 19th International Conference on X-ray Absorption Fine Structure (XAFS2026) will be held in Chiang Mai, Thailand, from 21 to 26 June 2026. Organized under the auspices of the International X-ray Absorption Society (IXAS), this triennial event serves as the foremost global forum for researchers and practitioners in the field of X-ray absorption spectroscopy.

XAFS2026 will bring together scientists, beamline specialists, and interdisciplinary experts to exchange knowledge, foster collaboration, and explore emerging frontiers in XAFS-related research. The scientific program will encompass eleven main topics:

• Advanced X-ray spectroscopies

• Computational and theoretical methods

• Materials science

• Catalysis

• Environmental sciences

• Biological systems

• Geosciences

• Energy-related applications

• Industrial and applied research

• Instrumentation and beamline development

• Cultural heritage and archaeology

Hosted in one of Southeast Asia's most culturally vibrant cities, XAFS2026 is committed to promoting inclusivity, accessibility, and international engagement. The conference welcomes participation from all career stages and geographic regions.

The course aims at providing a comprehensive overview of the whole image 
processing pipeline in Electron Tomography (ET) from the movie alignment 
of the tilt series, 3D reconstruction of the tomogram, particle 
identification, and subtomogram averaging, *all inside Scipion 
integration framework*.

The course is aimed at researchers of all levels wanting to adopt 
electron microscopy as one of the tools at their disposal for 
elucidating biological structures.

This 5-day course is largely aimed at structural biologists with EM maps suitable for modelling building and refinement.  This course will host some of the leading software developers and provide ample contact time to allow delegates to discuss their data in detail alongside traditional lectures and tutorials.  This is a comprehensive course for EM model building covering advanced use of LocScale, ModelAngelo, Buccaneer, findMySequence-checkMySequence, EM_placement, Coot/Moorhen, TEMPy-REFF, ISOLDE, Refmac-Servalcat, Privateer, new validation tools and AlphaFold-DB & EMDB/PDBe updates. It will cover all aspects of modelling building including: map optimisation, automated model building, model fitting, medium resolution refinement, high resolution refinement, interactive refinement, validation and deposition.
