Insects use their sense of smell to find food, mating partners or to avoid danger. Carbon dioxide is an important cue for insects. Interestingly, fruitflies reject it strongly, while mosquitoes use it to find human or animal hosts for blood feeding. CO2 and its detection is a field of active research, because we hope to contribute knowledge to the fight against malaria and other deadly diseases. Certain genes could have played an important role during evolution making mosquitoes attracted and fruitflies repelled by CO2. more
Our movements are controlled by nerve cells located in the spinal cord. Before birth, these cells have to be connected with the correct muscles, some of which are situated far away from the spinal cord, like the muscles of the lower leg. To reach their destination, the processes of nerve cells have to cover large distances, growing through different tissues. How do they find their way in this complex environment? Scientists from the Max Planck Institute of Neurobiology use genetic and cell biological methods to study the molecular signals that help the growing nerves navigate through the body. more
