This week, Jana, Manuel, Ahel, and Peter participated in the Young Researchers Meeting (YRM) at the IEB 2026 conference @iebcas.bsky.social, where they presented their research.

Six months in with the Mirava Polyscope super-resolution microscope from Abberior Instruments at the Imaging Facility of IEB — and a great advanced training led by Gero Schlötel.
Hands-on insights, practical tips, and expert guidance. Exactly all we needed.

The HeatDDR doctoral network training school in full swing @iebcas.bsky.social @pecinka-grp.bsky.social @zeiss-microscopy.bsky.social #microscopy #DNAdamage

PhD students from across Europe have arrived in Olomouc for the international HeatDDR training school. This week, they are exploring how plants respond to DNA damage caused by heat stress – a topic closely linked to climate change.

We had the pleasure of hosting an excellent lecture by Christian Fankhauser at the Institute of Experimental Botany in Prague.
Thank you for an inspiring visit, outstanding talk, and the opportunity to exchange ideas during individual meetings.
