On 28 June, it's that time again: the Long Night of Science will take place from 5 pm to midnight in Berlin and also in Adlershof! Come around and take a look behind the scenes of our exciting research.
We will open the doors of our laboratories and BESSY II light source to you, your families and friends. Meet scientists who will tell you about the latest breakthroughs in energy and materials research: batteries, solar cells and catalysts are the focus of our work at HZB!
Children of all ages will also have lots to discover. An extra programme with experiments in our school laboratory awaits you.
> Please find here the programme (BESSY II light source and Kekuléstraße)
And last but not least, some great news: the Long Night of Science is celebrating its 25th anniversary. To mark the occasion, there is a special gift: all tickets cost just 5 euros this year! Info Tickets
We cannot wait to see you at Helmholtz-Zentrum Berlin!
- A duo for BESSY III light sourceSince 1 March 2026, Renske van der Veen and Andreas Jankowiak have formed the leadership team of BESSY III. Together, they will drive forward HZB’s central project: the planning and realisation of BESSY III light source in Berlin-Adlershof. Here, they talk about their motivation, the next steps, and why BESSY III is a a cross-generational project.
- Protein crystallography at BESSY II: faster, better and more and more automaticMany diseases are linked to malfunctions of proteins in the organism. The three-dimensional architecture of these molecules is often highly complex, but it can provide valuable insights into biological processes and the development of drugs. X-ray diffraction at the MX beamlines of BESSY II can be used to decipher the 3D structure of proteins. To date, more than 5000 structures have been solved at the three MX beamlines. Here, we present a review and an outlook with Manfred Weiss, head of the research group for macromolecular crystallography.
- What Zinc concentration in teeth revealsTeeth are composites of mineral and protein, with a bulk of bony dentin that is highly porous. This structure is allows teeth to be both strong and sensitive. Besides calcium and phosphate, teeth contain trace elements such as zinc. Using complementary microscopy imaging techniques, a team from Charité Berlin, TU Berlin and HZB has quantified the distribution of natural zinc along and across teeth in 3 dimensions. The team found that, as porosity in dentine increases towards the pulp, zinc concentration increases 5~10 fold. These results help to understand the influence of widely-used zinc-containing biomaterials (e.g. filling) and could inspire improvements in dental medicine.
