The Institutional Repositories Working Group of the Spanish Network of University and CSIC Li-braries (REBIUN, https://www.rebiun.org/grupos-trabajo/repositorios) is working on implementingthe openCOST metadata schema as there is an interest in showing information about open accesspublishing costs in a commonly agreed way. The analysis and beta implementation of the metadataschema is being advanced by the DSpace repositories subgroup and ongoing work has focused onidentifying the most relevant metadata given the data model in place in such repositories as wellas the type and granularity of OA publishing cost information collected by their institutions.

Since 2021 the oa.finder displays information on list-price APCs for around 5.000 pure OA journalsas derived from the DOAJ and more than 6.000 hybrid journals that come from an own longitudinaldata collection. The later increased over time adding more publishers and hybrid journals to thecollection. [...]

Several projects in the field of open access transformation share the common goal with openCost ofcreating cost transparency by focussing on interrelated topics and tasks such as funding, financialsustainability, budgeting, monitoring, appropriate workflows and tools, networking, and promoting exchange. Four projects are particularly closely linked: Since 2019, open-access.network has created an information and networking platform on the topic of open access, organised workshops onthe information budget, has published several resources on open access funding, and has launchedfocus groups to connect stakeholders and initiatives and improve their exchange.

Planned upgrades of the European X-Ray Free Electron Laser (EuXFEL) target higher photon energy and a high duty-cycle operation up to CW-operation using a superconducting RF gun with lower gradient. An operation in this regime though critically depends on improvements of the beam slice emittance of the electron gun. [...]

A terahertz (THz) free-electron laser (FEL) is developed at the Photo Injector Test Facility at DESY in Zeuthen (PITZ) to conduct proof-of-principle experiments for the European-XFEL. Narrowband 3 THz pulses with energies up to 100 μJ are generated using a single-pass, high-gain THz FEL driven by high-brightness electron beams. [...]

The dose rates from conventional (CDR) up to ultra-high 1014Gy/s(UHDR) are being enabled by the full FLASHlab@PITZ-beamline, commissioned in August 2025 for radiobiological studies at the Photo-Injector Test facility at DESY in Zeuthen (PITZ) with the Technical University of Applied Sciences Wildau. Dose rate escalation holds potential to expand the therapeutic window of cancer radiotherapy. [...]

FLASH irradiation has emerged as a promising approach to reduce normal tissue toxicity while preserving tumor control, creating a need for sensitive models to study its biological effects. Zebrafish (Danio rerio) embryos provide such a model, offering a vertebrate system with high developmental sensitivity, genetic similarity to humans, and suitability for preclinical radiation biology research. [...]

Zebrafish (Danio rerio) embryos are a well-recognized model organism for assessing toxicological effects due to their approximately 70% genetic similarity to humans, rapid development, and transparent embryonic stages. Investigating toxic effects in zebrafish embryos provides valuable insights into effects of cancer treatment on normal tissue. [...]
