A new technique based on labelled sugar molecules is providing previously unknown insights into the inner ear. A study by the University of Konstanz and Charité-Universitätsmedizin Berlin shows that the cupula in the inner ear of zebrafish completely regenerates within approximately two months. These findings open up a new avenue for research into sudden hearing loss and acute disorders of the sense of balance.

Brain metastases are among the most serious complications of breast cancer. Researchers at Heidelberg University, DKFZ, and UKHD have concluded an investigation of the immune cells in the brain tissue surrounding these breast cancer brain metastases. Their findings: spatial distribution patterns of immune cells are associated with prolonged patient survival. These findings could help to guide use of immunotherapies for breast cancer patients.

The cities of Heidelberg and Mainz want to work closely together in the future: Their aim is to further develop the Neckar-Rhine-Main region as an international innovation and biotech region. To this end, Heidelberg Mayor Würzner and Mainz Mayor Haase signed a MoU at Heidelberg City Hall on Friday, April 24, 2026. Those responsible for the central innovation and development structures of both cities also took part in the signing.

Prof. Dr. Halbritter has served as the new Medical Director of the Department of Nephrology at the Medical Center – University of Freiburg since April 2026. With his expertise, he is enhancing care for patients with kidney disease: The goal is to prevent kidney failure through early diagnosis and the implementation of strategies to slow disease progression. For cases where kidney failure has already occurred, the focus is on organ replacement.

Within biological cells, molecules are constantly in motion. Investigating these motions, however, is still difficult, due to the fact that these processes occur on very small length and time scales. To overcome these challenges, researchers from HITS and MPI-P have developed a simulation method that works rapidly and can predict chemical processes in cells with high precision. Their findings have been published in Nature Communications.
