James Logan: How we're using dogs to sniff out malaria

The video discusses the challenges of detecting malaria, highlighting the role of smell in disease diagnosis. It explores how mosquitoes are attracted to malaria-infected individuals and presents research on using dogs to detect malaria through smell. The video concludes with potential future technologies for disease detection.
