An imaging technique developed by Freiburg researchers provides insights into cardiac arrhythmias that can cause sudden cardiac death in animal models. The changes discovered could explain why even seemingly healthy people are sometimes affected.

Researchers from the Cluster of Excellence CIBSS have demonstrated that an actin scaffold stabilizes the cell nucleus upon mechanical stress. This protective mechanism helps cancer cells to avoid dying during their migration in the body. In the long term, targeted interventions in this mechanism could help to prevent metastases.

Powerful AI systems using synthetic training data

AI systems for image analysis are only as good as the data on which they are trained. The Göppingen-based start-up MIRA Vision has developed a novel method for generating synthetic, photorealistic images, enabling the efficient creation of large, high-quality training datasets. An intuitive platform also allows researchers to evaluate microscopy images with ease.

Since their discovery in 2004, the grid cells in the brain, which are important for our orientation, have been regarded as a kind of “GPS in the head.” However, scientists at the DKFZ and Heidelberg University Hospital have now shown that grid cells work much more flexibly than previously assumed. In experiments with mice, the researchers found that the cells adapt their activity to different reference points depending on the situation.

Why is blood cancer particularly aggressive in some patients? Researchers at Ulm University Hospital have characterised a mutation in the so-called NOTCH1 gene that significantly influences the prognosis of chronic lymphocytic leukaemia (CLL). Remarkably, this mutation is located in the non-coding region of the gene – an area of DNA long considered less relevant for disease mechanisms.
