MIT and Georgia Tech Build 3D Model That Predicts How Mosquitoes Track Human Targets
Researchers at MIT and Georgia Tech developed the first three-dimensional model of mosquito flight, showing how visual and chemical cues — particularly CO₂ from breath — determine how mosquitoes home in on human targets.
Why it matters
Mosquitoes are the world's deadliest animals, responsible for over 700,000 human deaths per year through diseases like malaria, dengue, and Zika. Understanding exactly how they find hosts opens new pathways for developing more effective repellents, traps, and disease prevention strategies.

Where do you stand?
Should governments prioritize funding research into mosquito-borne disease prevention over treatment?
Should genetically modified mosquitoes that cannot transmit disease be released into the wild to combat malaria?
Should wealthy nations do more to fund mosquito disease prevention in low-income tropical countries?
