Mosquitoes seek us out by detecting the carbon dioxide we exhale and our natural body odors. A research team from Riverside, California demonstrates that the same group of neurons act as detectors for both, thus establishing them as a prime target for manipulation. They use computational methods to find compounds that alter the mosquitoes' behaviour and potentially help us dodge the relentless mosquitoes -- both by making ourselves invisible to them as well as luring them into traps.
