Researchers observed that certain cows emit chemicals that deter insects. Inspired by this, scientists at the Rothamsted Institute explored if humans produce similar chemicals that repel mosquitoes. They collected human skin odours and conducted experiments using a Y-shaped tube to test mosquito responses. The study revealed that some individuals produce chemicals that hinder mosquitoes' ability to detect them. The team isolated these chemicals to develop a natural insect repellent, potentially impacting mosquito-borne diseases like malaria.

What was the goal of isolating the masking chemicals produced by some people?

What potential impact could the research at Rothamsted have on public health?
