When a heart attack strikes, the body’s attempt to heal leaves behind scar tissue that weakens the heart’s pumping power. Now, scientists from Würzburg and Freiburg have mapped the heart at unprecedented molecular detail, showing how immune and connective tissue cells orchestrate this scarring process. Their findings could lay the foundation for therapies that support heart repair and improve recovery after a heart attack.
Researchers at Helmholtz Munich and the Technical University of Munich (TUM) have developed Nicheformer, the first large-scale foundation model that integrates single-cell analysis with spatial transcriptomics. Trained on more than 110 million cells, it offers a new way to study how cells are organized and interact in tissues – knowledge that is crucial for understanding health and disease.
What audible components of animal communication serve an alerting function? A team of researchers from the University of Konstanz, Tel Aviv University and Bar-Ilan University have analyzed whether the so-called wails, which initiate rock hyraxes’ songs, serve that purpose. They published their results in the journal Animal Behaviour.
