Exosomes (red arrow) are small vesicles that contain proteins and nucleic acids. Researchers at Johannes Gutenberg University Mainz (JGU) have discovered a new form of communication between different cell types in the brain. Nerve cells interact with neighboring glial cells, which results in a transfer of protein and genetic information. Nerve cells are thus protected against stressful growth conditions. The study undertaken by the Mainz-based cell biologists shows how reciprocal communication between the different cell types contributes to neuronal integrity. Their results have been recently published in the journal PLOS Biology.

Scientists from Griffith University have taken part in an international study which has revealed the genetic secrets of how a small bird can survive in one of the most hostile environments on earth.
