A time resolved X-ray tomography by Paul H. Kamm, HZB, has won the second Jury prize and is the winner of the Helmholtz Imaging conference Partizipants Choice Award in this year’s competition. It shows a 3D snapshot of a laser welding process. Among the 20 most beautiful images is also a microscopy image of a solar cell by Yannic Kerkhoff and Daniel Abou Ras, HZB.

At Helmholtz, more than 8,000 doctoral candidates conduct research. Eleven of them have now been honored for their original and outstanding work, among them Dr Israel Ibukun Olaniyan from the HZB. His doctoral thesis "Ferroelectricity at the nanoscale in epitaxial BaTiO₃ on silicon" in the group of Professor Catherine Dubourdieu represents a step towards a new nanoelectronics based on topological defects, that can potentially help to create an energy efficient information technology.

The team at the IRIS beamline at BESSY II has created a new experimental option: They achieved infrared nanoscopy with a spatial resolution of around 50 nm at very long THz wavelengths. This was possible thanks to a temporal pattern of light pulses known as the low-alpha operating mode at BESSY II. Worldwide, BESSY II is the only synchrotron light source at which users could perform nanoscopy in a single setup from 25 to 4000 cm^-1, a unique opportunity for ultra-broadband characterisation of complex materials at the nanoscale in both the life sciences and materials sciences.

The thinner an iron film, the more easily it can be demagnetised by a laser pulse. Researchers at the University of Duisburg-Essen, working with Helmholtz-Zentrum Berlin and other partners, have discovered why: the key lies in the magnetic order at the material's interfaces. In the long term, these findings could contribute to the development of new technologies for magnetic data storage. The results have been published in the scientific journal Advanced Science.

Artificial intelligence is increasingly being used to predict the properties of new materials. A research team from Jena and the United States now shows in a study published in the journal Nature Computational Science that when language models are used for this purpose, they reliably identify which types of atoms a material contains. However, they make insufficient use of information about how those atoms are arranged in space. Neither larger models nor additional training data resolve this weakness. For material properties that depend strongly on structure, AI models specifically designed to process spatial relationships are therefore the more reliable choice. (DOI: 10.1038/s43588-026-01045-2)

We mourn the loss of our former colleague Roland Steitz who passed away far too soon on 7 October 2026 at the age of 66, following a long battle with a treacherous illness. He was an internationally renowned expert in neutron research and was deeply committed to fostering connections within the neutron community worldwide. 

We mourn the loss of our former colleague Dr Andreas Gaupp who passed away far too soon on 8 October 2026 at the age of 78. With his passing, we have lost a brilliant thinker, a valued colleague and a mentor who, over the decades, had a decisive influence on the Helmholtz-Zentrum Berlin and the synchrotron radiation community.

A team at HZB has, for the first time, reported polar vortices in (BaTiO₃/SrTiO₃)₁₀ superlattices on silicon. These results expand the range of materials and substrates on which polar topological textures can occur and open up new options for incorporating complex ferroelectric states into silicon-based technologies.

Our warmest congratulations go to Peter Hegemann, Professor of Neuroscience and Experimental Biophysics at Humboldt University in Berlin. Together with Prof. Georg Nagel (Julius Maximilian University of Würzburg) and Prof. Karl Deisseroth (Stanford University, USA), he has been awarded the 2026 Nobel Prize in Physiology or Medicine. We are delighted for him, his team, Humboldt University and the entire Berlin scientific community.

Science is a key social and economic factor for Berlin. It creates jobs and adds value, attracts talent from all over the world, and enriches city life. To ensure that Berlin remains one of the world’s leading centres of science in the future, science must feature even more prominently on the political agenda. This is what BR50 stands for: over 50 non-university research institutions, including the HZB, are joining forces in this network. Following the election in Berlin, BR50 is now addressing politicians with a position paper, accompanied by the campaign “𝗪𝗶𝗿 𝗳𝗼𝗿𝘀𝗰𝗵𝗲𝗻 𝗳ü𝗿 𝗕𝗲𝗿𝗹𝗶𝗻.”
