Mosquitoes use carbon dioxide as a critical cue to sense if humans are nearby. This Primer explores a new study in PLOS Biology that reveals that carbon dioxide-sensing neurons in mosquitoes can ampli...

Comparative studies are essential for uncovering shared and divergent biological principles. Insects, with their extraordinary diversity, rich natural histories, and increasing experimental tractabil…

The early olfactory system is canonically described by a “one-receptor-to-one-neuron” model: each olfactory sensory neuron (OSN) expresses a single...

The mosquito Aedes aegypti′s human host-seeking behavior depends on the integration of multiple sensory cues. One of these cues, carbon dioxide (CO2), gates odorant and heat pathways and activates hos...
