The European Union is supporting the project over a period of five years to the tune of just under eight million euros.

Zebrafish can completely replace damaged heart muscle cells: The affected organ becomes fully functional again. Researchers at Ulm University have discovered that a specific cell-to-cell communication signal helps them to cope better with replication stress. This stress inhibits tissue regeneration in humans and mammals as they age. In Zebrafish a signalling protein ensures that the cells of the damaged organ continue to divide and thus multiply.

A protein with contradictory properties: Despite its large negative surface charge, it has a strong tendency to take up electrons, which are also negatively charged. The researchers discovered positively charged calcium ions inside the protein very near the electrons, counteracting their charge. They see this as a natural way of handling opposing electrical charges and allowing the protein to optimally fulfill its biological function.

New polymer for wound care - 09/01/2025

Thermoresponsive adhesive for pain-free removal of wound dressings

Plasters or wound dressings can only perform their intended function if they adhere securely to the skin.
