Researchers discover molecular light switch in photoreceptor cells

How our eyes detect and respond to changes in light intensity is determined by specialized cells in the eye called photoreceptors. In addition to converting light into electrical signals, effectively allowing us to see, rod-shaped ...

A protein that pulls the brake on nerve growth

During embryonic development, nerve cells form long, thin extensions that wire up the complex network of the brain. Scientists from the German Center for Neurodegenerative Diseases (DZNE) in Bonn have now identified a protein ...

Highly sensitive sensors to measure the heart and brain activity

Electrical signals measurements such as the ECG (electrocardiogram) can show how the human brain or heart works. Next to electrical signals magnetic signals also reveal something about the activity of these organs. They could ...
